Mining Claim Activity on Federal Land in the United States
Causey, J. Douglas
2007-01-01
Several statistical compilations of mining claim activity on Federal land derived from the Bureau of Land Management's LR2000 database have previously been published by the U.S Geological Survey (USGS). The work in the 1990s did not include Arkansas or Florida. None of the previous reports included Alaska because it is stored in a separate database (Alaska Land Information System) and is in a different format. This report includes data for all states for which there are Federal mining claim records, beginning in 1976 and continuing to the present. The intent is to update the spatial and statistical data associated with this report on an annual basis, beginning with 2005 data. The statistics compiled from the databases are counts of the number of active mining claims in a section of land each year from 1976 to the present for all states within the United States. Claim statistics are subset by lode and placer types, as well as a dataset summarizing all claims including mill site and tunnel site claims. One table presents data by case type, case status, and number of claims in a section. This report includes a spatial database for each state in which mining claims were recorded, except North Dakota, which only has had two claims. A field is present that allows the statistical data to be joined to the spatial databases so that spatial displays and analysis can be done by using appropriate geographic information system (GIS) software. The data show how mining claim activity has changed in intensity, space, and time. Variations can be examined on a state, as well as a national level. The data are tied to a section of land, approximately 640 acres, which allows it to be used at regional, as well as local scale. The data only pertain to Federal land and mineral estate that was open to mining claim location at the time the claims were staked.

This study describes event rates and associated costs from non-fatal work-related motor vehicle traffic crash (WR MVTC) injuries on public roads in New Zealand based on an analysis of the Accident Compensation Corporation (ACC) entitlement claims database. WR MVTC injury claims between July 2004 and June 2006 were identified from the ACC Motor Vehicle Account. Cross-sectional analyses were performed to describe the characteristics of the claims. Injury rates were estimated where appropriate. The overall age-standardised rate of non-fatal WR MVTC injury claims during the study period was 109 per 100,000 workers per year. The majority of claimants were male (75%) and New Zealand (NZ) European (67%), and one in three of these injuries occurred among plant and machine operators and assemblers. In contrast to rates of road traffic injury resulting in deaths and hospital admissions in NZ, younger and older workers had similar proportionate representation in the claims data. The total cost associated with the 1968 claims made during the 12 months from July 2004 to June 2005 was approximately NZ$6 million, with an average cost per claim of NZ$2884. To our knowledge this is the first published analysis of non-fatal WR MVTC injury claims in New Zealand. These analyses identify industry and demographic groups that appear to be at increased risk of WR MVTC injuries that could be targeted for preventive interventions. However, a number of limitations in the database, including uncertainties regarding the definition and coding of crashes deemed as "work-related", under-reporting of claims, and lack of a reliable indicator of injury severity significantly compromised our ability to interpret the results. Considerable improvement in the quality and reporting of claims data is required to facilitate the utility of this information to inform injury prevention strategies.

Background The Claim Evaluation Tools database contains multiple-choice items for measuring people’s ability to apply the key concepts they need to know to be able to assess treatment claims. We assessed items from the database using Rasch analysis to develop an outcome measure to be used in two randomised trials in Uganda. Rasch analysis is a form of psychometric testing relying on Item Response Theory. It is a dynamic way of developing outcome measures that are valid and reliable. Objectives To assess the validity, reliability and responsiveness of 88 items addressing 22 key concepts using Rasch analysis. Participants We administrated four sets of multiple-choice items in English to 1114 people in Uganda and Norway, of which 685 were children and 429 were adults (including 171 health professionals). We scored all items dichotomously. We explored summary and individual fit statistics using the RUMM2030 analysis package. We used SPSS to perform distractor analysis. Results Most items conformed well to the Rasch model, but some items needed revision. Overall, the four item sets had satisfactory reliability. We did not identify significant response dependence between any pairs of items and, overall, the magnitude of multidimensionality in the data was acceptable. The items had a high level of difficulty. Conclusion Most of the items conformed well to the Rasch model’s expectations. Following revision of some items, we concluded that most of the items were suitable for use in an outcome measure for evaluating the ability of children or adults to assess treatment claims.

Published reports have shown the prevalence and incidence of gastroesophageal reflux disease (GERD) is increasing in Japan. The objective of this study is to examine change in GERD incidence, and to understand current patient demographics, medical costs, treatment status, and the suitability of current treatment based on analysis of an insurance claims database. An insurance claims database with data on ∼1.9 million company employees from January 2005 to May 2015 was used. Prevalence, demographics, and medical costs were analyzed by cross-sectional analysis, and incidence and treatment status were analyzed by longitudinal analysis among newly-diagnosed GERD patients. GERD prevalence in 2014 was 3.3% among 20-59 year-olds, accounting for 40,134 people in the database, and GERD incidence increased from 0.63% in 2009 to 0.98% in 2014. In 2014, mean medical cost per patient per month for GERD patients aged 20-59 was JPY 31,900 (USD 266 as of January 2016), which was ∼2.4-times the mean national healthcare cost. The most frequently prescribed drugs for newly-diagnosed GERD patients were proton pump inhibitors (PPIs). Although PPIs were prescribed more often in patients with more doctor visit months, over 20% of patients that made frequent doctor visits (19 or more visits during a 24 calendar months period) were prescribed PPIs during only 1 calendar month or not at all. The database included only reimbursable claims data and, therefore, did not cover over-the-counter drugs. The database also consisted of employee-based claims data, so included little data on people aged 60 years and older. Given the increasing incidence of GERD in Japan there is a need for up-to-date information on GERD incidence. This study suggests that some GERD patients may not be receiving appropriate treatment according to Japanese guidelines, which is needed to improve symptom control.

Many pharmacoepidemiologic studies using large-scale databases have recently been utilized to evaluate the safety and effectiveness of drugs in Western countries. In Japan, however, conventional methodology has been applied to postmarketing surveillance (PMS) to collect safety and effectiveness information on new drugs to meet regulatory requirements. Conventional PMS entails enormous costs and resources despite being an uncontrolled observational study method. This study is aimed at examining the possibility of database research as a more efficient pharmacovigilance approach by comparing a health care claims database and PMS with regard to the characteristics and safety profiles of sertraline-prescribed patients. The characteristics of sertraline-prescribed patients recorded in a large-scale Japanese health insurance claims database developed by MinaCare Co. Ltd. were scanned and compared with the PMS results. We also explored the possibility of detecting signals indicative of adverse reactions based on the claims database by using sequence symmetry analysis. Diabetes mellitus, hyperlipidemia, and hyperthyroidism served as exploratory events, and their detection criteria for the claims database were reported by the Pharmaceuticals and Medical Devices Agency in Japan. Most of the characteristics of sertraline-prescribed patients in the claims database did not differ markedly from those in the PMS. There was no tendency for higher risks of the exploratory events after exposure to sertraline, and this was consistent with sertraline's known safety profile. Our results support the concept of using database research as a cost-effective pharmacovigilance tool that is free of selection bias . Further investigation using database research is required to confirm our preliminary observations. Copyright © 2018. Published by Elsevier Inc.
The role of insurance claims databases in drug therapy outcomes research.
Lewis, N J; Patwell, J T; Briesacher, B A

The use of insurance claims databases in drug therapy outcomes research holds great promise as a cost-effective alternative to post-marketing clinical trials. Claims databases uniquely capture information about episodes of care across healthcare services and settings. They also facilitate the examination of drug therapy effects on cohorts of patients and specific patient subpopulations. However, there are limitations to the use of insurance claims databases including incomplete diagnostic and provider identification data. The characteristics of the population included in the insurance plan, the plan benefit design, and the variables of the database itself can influence the research results. Given the current concerns regarding the completeness of insurance claims databases, and the validity of their data, outcomes research usually requires original data to validate claims data or to obtain additional information. Improvements to claims databases such as standardisation of claims information reporting, addition of pertinent clinical and economic variables, and inclusion of information relative to patient severity of illness, quality of life, and satisfaction with provided care will enhance the benefit of such databases for outcomes research.

This study aims to quantify the magnitude of missed dispensings in commercial claims databases. A retrospective cohort study has been used linking PharMetrics, a commercial claims database, to a prescription database (LRx) that captures pharmacy dispensings independently of payment method, including cash transactions. We included adults with dispensings for opioids, diuretics, antiplatelet medications, or anticoagulants. To determine the degree of capture of dispensings, we calculated the number of subjects with the following: (1) same number of dispensings in both databases; (2) at least one dispensing, but not all dispensings, missed in PharMetrics; and (3) all dispensings missing in PharMetrics. Similar analyses were conducted using dispensings as the unit of analysis. To assess whether a dispensing in LRx was in PharMetrics, the dispensing in PharMetrics had to be for the same medication class and within ±7 days in LRx. A total of 1 426 498 subjects were included. Overall, 68% of subjects had the same number of dispensings in both databases. In 13% of subjects, PharMetrics identified ≥1 dispensing but also missed ≥1 dispensing. In 19% of the subjects, PharMetrics missed all the dispensings. Taking dispensings as the unit of analysis, 25% of the dispensings present in LRx were not captured in PharMetrics. These patterns were similar across all four classes of medications. Of the dispensings missing in PharMetrics, 48% involved a subject who had >1 health insurance plan. Commercial claims databases provide an incomplete picture of all prescriptions dispensed to patients. The lack of capture goes beyond cash transactions and potentially introduces substantial misclassification bias. © 2017 The Authors.

An enormous amount of information relevant to public health is being generated directly by online communities. To explore the feasibility of creating a dataset that links patient-reported outcomes data, from a Web-based survey of US patients with multiple sclerosis (MS) recruited on open Internet platforms, to health care utilization information from health care claims databases. The dataset was generated by linkage analysis to a broader MS population in the United States using both pharmacy and medical claims data sources. US Facebook users with an interest in MS were alerted to a patient-reported survey by targeted advertisements. Eligibility criteria were diagnosis of MS by a specialist (primary progressive, relapsing-remitting, or secondary progressive), ≥12-month history of disease, age 18-65 years, and commercial health insurance. Participants completed a questionnaire including data on demographic and disease characteristics, current and earlier therapies, relapses, disability, health-related quality of life, and employment status and productivity. A unique anonymous profile was generated for each survey respondent. Each anonymous profile was linked to a number of medical and pharmacy claims datasets in the United States. Linkage rates were assessed and survey respondents' representativeness was evaluated based on differences in the distribution of characteristics between the linked survey population and the general MS population in the claims databases. The advertisement was placed on 1,063,973 Facebook users' pages generating 68,674 clicks, 3719 survey attempts, and 651 successfully completed surveys, of which 440 could be linked to any of the claims databases for 2014 or 2015 (67.6% linkage rate). Overall, no significant differences were found between patients who were linked and not linked for educational status, ethnicity, current or prior disease-modifying therapy (DMT) treatment, or presence of a relapse in the last 12 months. The frequencies of the most common MS symptoms did not differ significantly between linked patients and the general MS population in the databases. Linked patients were slightly younger and less likely to be men than those who were not linkable. Linking patient-reported outcomes data, from a Web-based survey of US patients with MS recruited on open Internet platforms, to health care utilization information from claims databases may enable rapid generation of a large population of representative patients with MS suitable for outcomes analysis.

Emergency department (ED) use in Quebec may be measured from varied sources, eg, patient's self-reports, hospital medical charts, and provincial health insurance claims databases. Determining the relative validity of each source is complicated because none is a gold standard. We sought to compare the validity of different measures of ED use without arbitrarily assuming one is perfect. Data were obtained from a nursing liaison intervention study for frail seniors visiting EDs at 4 university-affiliated hospitals in Montreal. The number of ED visits during 2 consecutive follow-up periods of 1 and 4 months after baseline was obtained from patient interviews, from medical charts of participating hospitals, and from the provincial health insurance claims database. Latent class analysis was used to estimate the validity of each source. The impact of the following covariates on validity was evaluated: hospital visited, patient's demographic/clinical characteristics, risk of functional decline, nursing liaison intervention, duration of recall, previous ED use, and previous hospitalization. The patient's self-report was found to be the least accurate (sensitivity: 70%, specificity: 88%). Claims databases had the greatest validity, especially after defining claims made on consecutive days as part of the same ED visit (sensitivity: 98%, specificity: 98%). The validity of the medical chart was intermediate. Lower sensitivity (or under-reporting) on the self-report appeared to be associated with higher age, low comorbidity and shorter length of recall. The claims database is the most valid method of measuring ED use among seniors in Quebec compared with hospital medical charts and patient-reported use.
Practice Benchmarking in the Age of Targeted Auditing
Langdale, Ryan P.; Holland, Ben F.
2012-01-01
The frequency and sophistication of health care reimbursement auditing has progressed rapidly in recent years, leaving many oncologists wondering whether their private practices would survive a full-scale Office of the Inspector General (OIG) investigation. The Medicare Part B claims database provides a rich source of information for physicians seeking to understand how their billing practices measure up to their peers, both locally and nationally. This database was dissected by a team of cancer specialists to uncover important benchmarks related to targeted auditing. All critical Medicare charges, payments, denials, and service ratios in this article were derived from the full 2010 Medicare Part B claims database. Relevant claims were limited by using Medicare provider specialty codes 83 (hematology/oncology) and 90 (medical oncology), with an emphasis on claims filed from the physician office place of service (11). All charges, denials, and payments were summarized at the Current Procedural Terminology code level to drive practice benchmarking standards. A careful analysis of this data set, combined with the published audit priorities of the OIG, produced germane benchmarks from which medical oncologists can monitor, measure and improve on common areas of billing fraud, waste or abuse in their practices. Part II of this series and analysis will focus on information pertinent to radiation oncologists. PMID:23598847

To determine the characteristics of medical negligence claims arising from otological practice. Retrospective analysis of medical negligence claims contained in the National Health Service Litigation Authority (NHSLA) database. Claims relating to otology and neurotology between 1995 and 2010 were obtained from the NHSLA database and analyzed for cause of injury, type of injury, outcome of claim and costs. Over 15 years there were 137 claims in otology, representing 26% of all the claims in otolaryngology. Of these, 116 have been closed, and 84% of closed claims resulted in payment. Of the 97 successful claims, 63 were related to operative complications. This included six cases of wrong side/site surgery, and 15 cases of inadequate informed consent. The most common injuries claimed were hearing loss, facial paralysis, and additional/unnecessary surgery. Middle ear ventilation and mastoid surgery were the procedures most commonly associated with a successful claim. There were 15 successful claims of misdiagnosis/delayed diagnosis, with chronic suppurative otitis media the condition most frequently missed. There were nine successful claims related to outpatient procedures, of which seven were for aural toilet and six claims of medical mismanagement, including three cases of ototoxicity from topical medications. There were also four successful claims for morbidity due to delayed surgery. This is the first study to report outcomes of negligence claims in otology. Claims in otology are associated with a high success rate. A significant proportion of claims are not related to surgery and represent areas where safety should also be addressed.

Mining Claim Activity on Federal Land for the Period 1976 through 2003
Causey, J. Douglas
2005-01-01
Previous reports on mining claim records provided information and statistics (number of claims) using data from the U.S. Bureau of Land Management's (BLM) Mining Claim Recordation System. Since that time, BLM converted their mining claim data to the Legacy Repost 2000 system (LR2000). This report describes a process to extract similar statistical data about mining claims from LR2000 data using different software and procedures than were used in the earlier work. A major difference between this process and the previous work is that every section that has a mining claim record is assigned a value. This is done by proportioning a claim between each section in which it is recorded. Also, the mining claim data in this report includes all BLM records, not just the western states. LR2000 mining claim database tables for the United States were provided by BLM in text format and imported into a Microsoft? Access2000 database in January, 2004. Data from two tables in the BLM LR2000 database were summarized through a series of database queries to determine a number that represents active mining claims in each Public Land Survey (PLS) section for each of the years from 1976 to 2002. For most of the area, spatial databases are also provided. The spatial databases are only configured to work with the statistics provided in the non-spatial data files. They are suitable for geographic information system (GIS)-based regional assessments at a scale of 1:100,000 or smaller (for example, 1:250,000).

Acromegaly, a rare endocrine disorder, results from excessive growth hormone secretion, leading to multisystem-associated morbidities. Using 2 large nationwide databases, we estimated the annual incidence and prevalence of acromegaly in the U.S. We used 2008 to 2013 data from the Truven Health MarketScan ® Commercial Claims and Encounters Database and IMS Health PharMetrics healthcare insurance claims databases, with health plan enrollees <65 years of age. Study patients had ≥2 claims with acromegaly (International Classification of Diseases, 9th Revision, Clinical Modification Code [ICD-9CM] 253.0), or 1 claim with acromegaly and 1 claim for pituitary tumor, pituitary surgery, or cranial stereotactic radiosurgery. Annual incidence was calculated for each year from 2009 to 2013, and prevalence in 2013. Estimates were stratified by age and sex. Incidence was up to 11.7 cases per million person-years (PMPY) in MarketScan and 9.6 cases PMPY in PharMetrics. Rates were similar by sex but typically lowest in ≤17 year olds and higher in >24 year olds. The prevalence estimates were 87.8 and 71.0 per million per year in MarketScan and PharMetrics, respectively. Prevalence consistently increased with age but was similar by sex in each database. The current U.S. incidence of acromegaly may be up to 4 times higher and prevalence may be up to 50% higher than previously reported in European studies. Our findings correspond with the estimates reported by a recent U.S. study that used a single managed care database, supporting the robustness of these estimates in this population. Our study indicates there are approximately 3,000 new cases of acromegaly per year, with a prevalence of about 25,000 acromegaly patients in the U.S. CT = computed tomography GH = growth hormone IGF-1 = insulin-like growth factor 1 ICD-9-CM Code = International Classification of Diseases, 9th Revision, Clinical Modification Codes MRI = magnetic resonance imaging PMPY = per million person-years.

To explore epidemiological trends in type 2 diabetes mellitus (T2D) in the US between 2007 and 2012 using a large US claims database, with a particular focus on demographics, prevalence, newly-diagnosed cases, and comorbidities. Truven Health MarketScan® Databases were used to identify patients with claims evidence of T2D in the years 2007 and 2012. Newly-diagnosed T2D was characterized by an absence of any T2D claims or related drug claims for 6months preceding the index claim. Demographic and comorbidity characteristics of the prevalent and new-onset T2D groups were compared and analyzed descriptively for trends over time. The overall prevalence of T2D remained stable from 2007 (1.24 million cases/15.07 million enrolled; 8.2%) to 2012 (2.04 million cases/24.52 million enrolled; 8.3%), while the percentage of newly-diagnosed cases fell dramatically from 2007 (152,252 cases; 1.1%) to 2012 (147,011 cases; 0.65%). The mean age of patients with prevalent T2D was similar in 2007 (60.6y) and 2012 (60.0y), while the mean age of newly-diagnosed T2D patients decreased by 3years from 2007 (57.7y) to 2012 (54.8y). Hypertension and hyperlipidemia were the most common comorbidities, evident in 50-75% of T2D patients, and increased markedly from 2007 to 2012 in both prevalent and new-onset T2D populations. Cardiovascular disease decreased slightly in prevalent (-0.9%) and new-onset (-2.8%) cases. This large US health claims database analysis suggests stabilization in prevalence and declining incidence of T2D over a recent 5-year period, a downward shift in age at T2D diagnosis, but increases in several comorbidities.

As Japan becomes a super-aging society, presentation of the best ways to provide medical care for the elderly, and the direction of that care, are important national issues. Elderly people have multi-morbidity with numerous medical conditions and use many medical resources for complex treatment patterns. This increases the likelihood of inappropriate medical practices and an evidence-practice gap. The present study aimed to: derive findings that are applicable to policy from an elucidation of the actual state of medical care for the elderly; establish a foundation for the utilization of National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), and present measures for the utilization of existing databases in parallel with NDB validation.Cross-sectional and retrospective cohort studies were conducted using the NDB built by the Ministry of Health, Labor and Welfare of Japan, private health insurance claims databases, and the Kyoto University Hospital database (including related hospitals). Medical practices (drug prescription, interventional procedures, testing) related to four issues-potential inappropriate medication, cancer therapy, chronic kidney disease treatment, and end-of-life care-will be described. The relationships between these issues and clinical outcomes (death, initiation of dialysis and other adverse events) will be evaluated, if possible.
ADA perceived disability claims: a decision-tree analysis.

The purpose of this study is to examine the possible interactions of predictor variables pertaining to perceived disability claims contained in a large governmental database. Specifically, it is a retrospective analysis of US Equal Employment Opportunity Commission (EEOC) data for the entire population of workplace discrimination claims based on the "regarded as disabled" prong of the Americans with Disabilities Act (ADA) definition of disability. The study utilized records extracted from a "master database" of over two million charges of workplace discrimination in the Integrated Mission System of the EEOC. This database includes all ADA-related discrimination allegations filed from July 26, 1992 through December 31, 2008. Chi squared automatic interaction detection (CHAID) was employed to analyze interaction effects of relevant variables, such as issue (grievance) and industry type. The research question addressed by CHAID is: What combination of factors are associated with merit outcomes for people making ADA EEOC allegations who are "regarded as" having disabilities? The CHAID analysis shows how merit outcome is predicted by the interaction of relevant variables. Issue was found to be the most prominent variable in determining merit outcome, followed by industry type, but the picture is made more complex by qualifications regarding age and race data. Although discharge was the most frequent grievance among charging parties in the perceived disability group, its merit outcome was significantly less than that for the leading factor of hiring.
Computer-aided auditing of prescription drug claims.
Iyengar, Vijay S; Hermiz, Keith B; Natarajan, Ramesh
2014-09-01
We describe a methodology for identifying and ranking candidate audit targets from a database of prescription drug claims. The relevant audit targets may include various entities such as prescribers, patients and pharmacies, who exhibit certain statistical behavior indicative of potential fraud and abuse over the prescription claims during a specified period of interest. Our overall approach is consistent with related work in statistical methods for detection of fraud and abuse, but has a relative emphasis on three specific aspects: first, based on the assessment of domain experts, certain focus areas are selected and data elements pertinent to the audit analysis in each focus area are identified; second, specialized statistical models are developed to characterize the normalized baseline behavior in each focus area; and third, statistical hypothesis testing is used to identify entities that diverge significantly from their expected behavior according to the relevant baseline model. The application of this overall methodology to a prescription claims database from a large health plan is considered in detail.

A comparative and quantitative analysis of various laser velocimeter signal processors is difficult because standards for characterizing signal bursts have not been established. This leaves the researcher to select a signal processor based only on manufacturers' claims without the benefit of direct comparison. The present paper proposes the use of a database of digitized signal bursts obtained from a laser velocimeter under various configurations as a method for directly comparing signal processors.

Accidental falls are very common in older hospital patients -- accounting for 32% of reported adult patient safety incidents in UK National Health Service (NHS) hospitals and occurring with similar frequency in settings internationally. In countries where the population is ageing, and care is provided in inpatient settings, falls prevention is therefore a significant and growing risk-management issue. Falls may lead to a variety of harms and costs, are cited in formal complaints and can lead to claims of clinical negligence. The NHS Litigation Authority (NHSLA) negligence claims database provides a novel opportunity to systematically analyse such (falls-related) claims made against NHS organisations in England and to learn lessons for risk-management systems and claims recording. To describe the circumstances and injuries most frequently cited in falls-related claims; to investigate any association between the financial impact (total cost), and the circumstances of or injuries resulting from falls in "closed" claims; to draw lessons for falls risk management and for future data capture on falls incidents and resulting claims analysis; to identify priorities for future research. A keyword search was run on the NHSLA claims database for April 1995 to February 2006, to identify all claims apparently relating to falls. Claims were excluded from further analysis if, on scrutiny, they had not resulted from falls, or if they were still "open" (ie, unresolved). From the narrative descriptions of closed claims (ie, those for which the financial outcome was known), we developed categories of "principal" and "secondary" injury/harm and "principal" and "contributory" circumstance of falls. For each category, it was determined whether cases had resulted in payment and what total payments (damages and costs) were awarded. The proportions of contribution-specific injuries or circumstances to the number of cases and to the overall costs incurred were compared in order to identify circumstances that tend to be more costly. Means were compared and tested through analysis of variance (ANOVA). The association between categorical variables was tested using the chi-square test. Of 668 claims identified by word search, 646 met inclusion criteria. The results presented are for the 479 of these that were "closed" at the time of the census. Of these, 290 (60.5%) had resulted in payment of costs or damages, with the overall total payment being 6,200,737 pound (mean payment 12,945 pound). All claims were settled out of court, so no legal rulings on establishing liability or causation of injury are available. "Falls whilst walking;" "from beds or trolleys" ("with and without bedrails applied") or "transferring/from a chair" were the most frequent source of these claims (n = 308, 64.2%). Clear secondary contributory circumstances were identified in 190 (39.7%) of closed claims. The most common circumstances cited were "perioperative/procedural incidents" (60, 12.5%) and "requests for bedrails being ignored" (54, 11.3%). For primary injuries, "hip/femoral/pelvic fracture" accounted for 203 (42.4%) of closed claims with total payments of 3,228,781 pound (52.1% of all payments), with a mean payment 15,905 pound per closed case. A "secondary" contributory circumstance could be attributed in 133 (27.8%) of cases. Of these, "delay in diagnosis of injury," "recurrent falls during admission" and "fatalities relating to falls" were the commonest circumstances (n = 59, 12.2%). Although falls are the highest volume patient safety incident reported in hospital trusts in England, they result in a relatively small number of negligence claims and receive a relatively low total payment (0.019% in both cases). The mean payment in closed claims is also relatively small. This may reflect the high average age of the people who fall and difficulty in establishing causation, especially where individuals are already frail when they fall. The patterns of claims and the narrative descriptions provide wider lessons for improving risk-management strategies. However, the inherent limitations and biases in the data routinely recorded for legal purposes suggest that for more informative research or actuarial claims analysis, more comprehensive and systematic data to be recorded for each incident claim are needed.

We determined the characteristics of medical negligence claims following tonsillectomy. Claims relating to tonsillectomy between 1995 and 2010 were obtained from the National Health Service Litigation Authority database. The number of open and closed claims was determined, and data were analyzed for primary injury claimed, outcome of claim, and associated costs. Over 15 years, there were 40 claims of clinical negligence related to tonsillectomy, representing 7.7% of all claims in otolaryngology. There were 34 closed claims, of which 32 (94%) resulted in payment of damages. Postoperative bleeding was the most common injury, with delayed recognition and treatment of bleeding alleged in most cases. Nasopharyngeal regurgitation as a result of soft palate fistulas or excessive tissue resection was the next-commonest cause of a claim. The other injuries claimed included dentoalveolar injury, bums, tonsillar remnants, and temporomandibular joint dysfunction. Inadequate informed consent was claimed in 5 cases. Clinical negligence claims following tonsillectomy have a high success rate. Although postoperative bleeding is the most common cause of negligence claims, a significant proportion of claims are due to rare complications of surgery. Informed consent should be tailored to the individual patient and should include a discussion of common and serious complications.
Pharmacoepidemiology resources in Ireland-an introduction to pharmacy claims data.
Sinnott, Sarah-Jo; Bennett, Kathleen; Cahir, Caitriona

Administrative health data, such as pharmacy claims data, present a valuable resource for conducting pharmacoepidemiological and health services research. Often, data are available for whole populations allowing population level analyses. Moreover, their routine collection ensures that the data reflect health care utilisation in the real-world setting compared to data collected in clinical trials. The Irish Health Service Executive-Primary Care Reimbursement Service (HSE-PCRS) community pharmacy claims database is described. The availability of demographic variables and drug-related information is discussed. The strengths and limitations associated using this database for conducting research are presented, in particular, internal and external validity. Examples of recently conducted research using the HSE-PCRS pharmacy claims database are used to illustrate the breadth of its use. The HSE-PCRS national pharmacy claims database is a large, high-quality, valid and accurate data source for measuring drug exposure in specific populations in Ireland. The main limitation is the lack of generalisability for those aged <70 years and the lack of information on indication or outcome.
Prevalence rates for depression by industry: a claims database analysis.
Wulsin, Lawson; Alterman, Toni; Timothy Bushnell, P; Li, Jia; Shen, Rui
2014-11-01
To estimate and interpret differences in depression prevalence rates among industries, using a large, group medical claims database. Depression cases were identified by ICD-9 diagnosis code in a population of 214,413 individuals employed during 2002-2005 by employers based in western Pennsylvania. Data were provided by Highmark, Inc. (Pittsburgh and Camp Hill, PA). Rates were adjusted for age, gender, and employee share of health care costs. National industry measures of psychological distress, work stress, and physical activity at work were also compiled from other data sources. Rates for clinical depression in 55 industries ranged from 6.9 to 16.2 %, (population rate = 10.45 %). Industries with the highest rates tended to be those which, on the national level, require frequent or difficult interactions with the public or clients, and have high levels of stress and low levels of physical activity. Additional research is needed to help identify industries with relatively high rates of depression in other regions and on the national level, and to determine whether these differences are due in part to specific work stress exposures and physical inactivity at work. Claims database analyses may provide a cost-effective way to identify priorities for depression treatment and prevention in the workplace.

To develop and validate a predictive model for first severe chronic obstructive pulmonary disease (COPD) exacerbation using health insurance claims data and to validate the risk measure of controller medication to total COPD treatment (controller and rescue) ratio (CTR). A predictive model was developed and validated in 2 managed care databases: Truven Health MarketScan database and Reliant Medical Group database. This secondary analysis assessed risk factors, including CTR, during the baseline period (Year 1) to predict risk of severe exacerbation in the at-risk period (Year 2). Patients with COPD who were 40 years or older and who had at least 1 COPD medication dispensed during the year following COPD diagnosis were included. Subjects with severe exacerbations in the baseline year were excluded. Risk factors in the baseline period were included as potential predictors in multivariate analysis. Performance was evaluated using C-statistics. The analysis included 223,824 patients. The greatest risk factors for first severe exacerbation were advanced age, chronic oxygen therapy usage, COPD diagnosis type, dispensing of 4 or more canisters of rescue medication, and having 2 or more moderate exacerbations. A CTR of 0.3 or greater was associated with a 14% lower risk of severe exacerbation. The model performed well with C-statistics, ranging from 0.711 to 0.714. This claims-based risk model can predict the likelihood of first severe COPD exacerbation. The CTR could also potentially be used to target populations at greatest risk for severe exacerbations. This could be relevant for providers and payers in approaches to prevent severe exacerbations and reduce costs.

Administrative claims contain detailed medication, diagnosis, and procedure data, but the lack of clinical outcomes for rheumatoid arthritis (RA) historically has limited their use in comparative effectiveness research. A claims-based algorithm was developed and validated to estimate effectiveness for RA from data for adherence, dosing, and treatment modifications. To implement the claims-based algorithm in a U.S. managed care database to estimate biologic cost per effectively treated patient. The cohort included patients with RA aged 18-63 years in the Optum Research Database who initiated biologic treatment between January 2007 and December 2010 and were continuously enrolled 6 months before through 12 months after the first claim for the biologic (the index date). Patients were categorized as effectively treated by the claims-based algorithm if they met all of the following 6 criteria in the 12-month post-index period: (1) a medication possession ratio ≥ 80% for subcutaneous biologics, or at least as many infusions as specified in U.S. labeling for intravenous biologics; (2) no increase in biologic dose; (3) no switch in biologics; (4) no new nonbiologic disease-modifying antirheumatic drug; (5) no new or increased oral glucocorticoid treatment; and (6) no more than 1 glucocorticoid injection. Drug costs (all biologics) and administration costs (intravenous biologics) were obtained from allowed amounts on claims. Biologic cost per effectively treated patient was defined as total 1-year biologic cost divided by the number of patients categorized by the algorithm as effectively treated with that index biologic. Sensitivity analysis was conducted to examine the total health care costs per effectively treated patient during the first year of biologic therapy. A total of 5,474 individuals were included in the analysis. The index biologic was categorized as effective by the algorithm for 28.9% of patients overall, including 30.6% for subcutaneous biologics and 22.1% for intravenous biologics. The index biologic was categorized as effective in the first year for 32.7% of etanercept (794/2,425), 32.3% of golimumab (40/124), 30.2% of abatacept (89/295), 27.7% of adalimumab (514/1,857), and 19.0% of infliximab (147/773) patients. Mean 1-year biologic cost per effectively treated patient, as defined in the algorithm, was lowest for etanercept ($43,935), followed by golimumab ($49,589), adalimumab ($52,752), abatacept ($62,300), and infliximab ($101,402). The rank order in the sensitivity analysis was the same, except for golimumab and etanercept. Using a claims-based algorithm in a large commercial claims database, etanercept was the most effective and had the lowest biologic cost per effectively treated patient with RA.

Improvements in anesthesia gas delivery equipment and provider training may increase patient safety. The authors analyzed patient injuries related to gas delivery equipment claims from the American Society of Anesthesiologists Closed Claims Project database over the decades from 1970s to the 2000s. After the Institutional Review Board approval, the authors reviewed the Closed Claims Project database of 9,806 total claims. Inclusion criteria were general anesthesia for surgical or obstetric anesthesia care (n = 6,022). Anesthesia gas delivery equipment was defined as any device used to convey gas to or from (but not involving) the airway management device. Claims related to anesthesia gas delivery equipment were compared between time periods by chi-square test, Fisher exact test, and Mann-Whitney U test. Anesthesia gas delivery claims decreased over the decades (P < 0.001) to 1% of claims in the 2000s. Outcomes in claims from 1990 to 2011 (n = 40) were less severe, with a greater proportion of awareness (n = 9, 23%; P = 0.003) and pneumothorax (n = 7, 18%; P = 0.047). Severe injuries (death/permanent brain damage) occurred in supplemental oxygen supply events outside the operating room, breathing circuit events, or ventilator mishaps. The majority (85%) of claims involved provider error with (n = 7) or without (n = 27) equipment failure. Thirty-five percent of claims were judged as preventable by preanesthesia machine check. Gas delivery equipment claims in the Closed Claims Project database decreased in 1990-2011 compared with earlier decades. Provider error contributed to severe injury, especially with inadequate alarms, improvised oxygen delivery systems, and misdiagnosis or treatment of breathing circuit events.
A Contemporary Medicolegal Analysis of Outpatient Medication Management in Chronic Pain.
Abrecht, Christopher R; Brovman, Ethan Y; Greenberg, Penny; Song, Ellen; Rathmell, James P; Urman, Richard D
2017-11-01
Opioids are frequently used in chronic pain management but are associated with significant morbidity and mortality in some patient populations. An important avenue for identifying complications-including serious or rare complications-is the study of closed malpractice claims. The present study is intended to complement the existing closed claims literature by drawing on claims from a more recent timeframe through a partnership with a large malpractice carrier, the Controlled Risk Insurance Company (CRICO). The goal of this study was to identify patient medical comorbidities and aberrant drug behaviors, as well as prescriber practices associated with patient injury and malpractice claims. Another objective was to identify claims most likely to result in payments and use this information to propose a strategy for reducing medicolegal risk. The CRICO Strategies Comparative Benchmarking System is a database of claims drawing from >350,000 malpractice claims from Harvard-affiliated institutions and >400 other academic and community institutions across the United States. This database was queried for closed claims from January 1, 2009, to December 31, 2013, and identified 37 cases concerning noninterventional, outpatient chronic pain management. Each file consisted of a narrative summary, including expert witness testimony, as well as coded fields for patient demographics, medical comorbidities, the alleged damaging event, the alleged injurious outcome, the total financial amount incurred, and more. We performed an analysis using these claim files. The mean patient age was 43.5 years, with men representing 59.5% of cases. Payments were made in 27% of cases, with a median payment of $72,500 and a range of $7500-$687,500. The majority of cases related to degenerative joint disease of the spine and failed back surgery syndrome; no patients in this series received treatment of malignant pain. Approximately half (49%) of cases involved a patient death. The use of long-acting opioids and medical conditions affecting the cardiac and pulmonary systems were more closely associated with death than with other outcomes. The nonpain medical conditions present in this analysis included obesity, obstructive sleep apnea, chronic obstructive pulmonary disease, hypertension, and coronary artery disease. Other claims ranged from alleged addiction to opioids from improper prescribing to alleged abandonment with withdrawal of care. The CRICO analysis suggested that patient behavior contributed to over half of these claims, whereas deficits in clinical judgment contributed to approximately 40% of the claims filed. Claims related to outpatient medication management in pain medicine are multifactorial, stemming from deficits in clinical judgment by physicians, noncooperation in care by patients, and poor clinical documentation. Minimization of both legal risk and patient harm can be achieved by carefully selecting patients for chronic opioid therapy and documenting compliance and improvement with the treatment plan. Medical comorbidities such as obstructive sleep apnea and the use of long-acting opioids may be particularly dangerous. Continuing physician education on the safest and most effective approaches to manage these medications in everyday practice will lead to both improved legal security and patient safety.

Non-unions and malunions are recognised to be complications of the treatment of long bone fractures. No previous work has looked at the implications of these complications from a medicolegal perspective. A complete database of litigation claims in Trauma and Orthopaedic Surgery was obtained from the NHS Litigation Authority. Two separate modalities of the treatment of long bone fractures were examined i) non-union and ii) acquired deformity. The type of complaint, whether defended or not, and costs were analysed. There were claims of which 97 related to non-union and 32 related to postoperative limb deformity. The total cost was £8.2 million over a 15-year period in England and Wales. Femoral and tibial non-unions were more expensive particularly if they resulted in amputation. Rotational deformity cost nearly twice as much as angulation deformities. The cosmetic appearances of rotational malalignment and amputation results in higher compensation; this reinforces an outward perception of outcome as being more important than harmful effects. Notwithstanding the limitations of this database, there are clinical lessons to be gained from these litigation claims. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.
Operating room fires: a closed claims analysis.
Mehta, Sonya P; Bhananker, Sanjay M; Posner, Karen L; Domino, Karen B
2013-05-01
To assess patterns of injury and liability associated with operating room (OR) fires, closed malpractice claims in the American Society of Anesthesiologists Closed Claims Database since 1985 were reviewed. All claims related to fires in the OR were compared with nonfire-related surgical anesthesia claims. An analysis of fire-related claims was performed to identify causative factors. There were 103 OR fire claims (1.9% of 5,297 surgical claims). Electrocautery was the ignition source in 90% of fire claims. OR fire claims more frequently involved older outpatients compared with other surgical anesthesia claims (P < 0.01). Payments to patients were more often made in fire claims (P < 0.01), but payment amounts were lower (median $120,166) compared to nonfire surgical claims (median $250,000, P < 0.01). Electrocautery-induced fires (n = 93) increased over time (P < 0.01) to 4.4% claims between 2000 and 2009. Most (85%) electrocautery fires occurred during head, neck, or upper chest procedures (high-fire-risk procedures). Oxygen served as the oxidizer in 95% of electrocautery-induced OR fires (84% with open delivery system). Most electrocautery-induced fires (n = 75, 81%) occurred during monitored anesthesia care. Oxygen was administered via an open delivery system in all high-risk procedures during monitored anesthesia care. In contrast, alcohol-containing prep solutions and volatile compounds were present in only 15% of OR fires during monitored anesthesia care. Electrocautery-induced fires during monitored anesthesia care were the most common cause of OR fires claims. Recognition of the fire triad (oxidizer, fuel, and ignition source), particularly the critical role of supplemental oxygen by an open delivery system during use of the electrocautery, is crucial to prevent OR fires. Continuing education and communication among OR personnel along with fire prevention protocols in high-fire-risk procedures may reduce the occurrence of OR fires.

Although China experienced great improvement in their health system, disputes between patients and doctors have increasingly intensified, reaching an unprecedented level. Retrospective analysis of medical malpractice litigation can discover the characteristics and fundamental cause of these disagreements. We analyzed medical malpractice litigation data from 1998 to 2011 for characteristics of claims via a litigation database within a nationwide database of cases (1086 cases) in China, including claims, liabilities, injures, and compensation payments. Among the cases analyzed, 76 percent of claims received compensation in civil judgment (640 out of 841), while 93 percent were fault liability in paid judgment (597 out of 640). The average time span between the occurrence of the injury dispute and closure of claims was 3 years. Twenty-two percent of claims (183 of 841) were caused by injury, poisoning, and other external causes. Seventy-nine percent of claims (472 of 597) were contributed to by errors in medical technology. The median damage compensation payment for death was significantly lower than for serious injuries (P < 0.001; death, $13270 [IQR, $7617-$23181]; serious injury, $23721 [IQR, $10367-$57058]). Finally, there was no statistically significant difference in the median mental compensation between minor injury, serious injury, and death (P = 0.836). The social reasons for the conflict and high payment were catastrophic out-of-pocket health-care expense in addition to the high expectations for treatment in China. There were no distinguishing features between China and other countries with respect to time of suits, facilities, and specialties in these claims. The compensation for damages in different medical injuries was unfair in China.
An Analysis of the Number of Medical Malpractice Claims and Their Amounts

Starting from an extensive database, pooling 9 years of data from the top three insurance brokers in Italy, and containing 38125 reported claims due to alleged cases of medical malpractice, we use an inhomogeneous Poisson process to model the number of medical malpractice claims in Italy. The intensity of the process is allowed to vary over time, and it depends on a set of covariates, like the size of the hospital, the medical department and the complexity of the medical operations performed. We choose the combination medical department by hospital as the unit of analysis. Together with the number of claims, we also model the associated amounts paid by insurance companies, using a two-stage regression model. In particular, we use logistic regression for the probability that a claim is closed with a zero payment, whereas, conditionally on the fact that an amount is strictly positive, we make use of lognormal regression to model it as a function of several covariates. The model produces estimates and forecasts that are relevant to both insurance companies and hospitals, for quality assurance, service improvement and cost reduction. PMID:27077661

Clinical documentation is a critical tool in supporting care provided to patients. Sound documentation provides a picture of clinical events that can be used to improve patient care. However, many other uses for clinical documentation are equally important. Such documentation informs clinical decision support tools, creates a legal record of patient care, assists in financial reimbursement of services, and serves as a repository for secondary data analysis. Conversely, poor documentation can impair patient safety and increase malpractice risk exposure by reflecting poor or inaccurate information that ultimately may guide patient care decisions.Through an examination of anesthesia-related closed claims, a descriptive qualitative study emerged, which explored the antecedents and consequences of documentation quality in the claims reviewed. A secondary data analysis utilized a database generated by the American Association of Nurse Anesthetists Foundation closed claim review team. Four major themes emerged from the analysis. Themes 1, 2, and 4 primarily describe how poor documentation quality can have negative consequences for clinicians. The third theme primarily describes how poor documentation quality that can negatively affect patient safety.

The frequency and features of malpractice lawsuits against dentists in Chile are not well known. To determine the magnitude and frequency of professional liability claims against dentists. A retrospective analysis of the Medical Liability Unit of the Legal Medical Service of Chile database. This public organization deals with most professional liability claims in Chile. Between 2007 and 2012, 3,990 expert opinions about liability of health care professionals were requested. Odontology was the fifth specialty most commonly sued and dentists, the second most frequently sued professionals. Sixty nine percent of cases originated in private clinics, which is coincident with a higher frequency of dentists working in private practice. Most petitioners were adult women and most claims originated from surgical interventions and infections. In 35% of claims against dentists, a violation of Lex Artis was confirmed, compared with 9% of all expert opinions that generated in the unit. Claims against dentists are more common than previously thought and these professionals should adopt preventive measures to avoid them.

Purpose To estimate and interpret differences in depression prevalence rates among industries, using a large, group medical claims database. Methods Depression cases were identified by ICD-9 diagnosis code in a population of 214,413 individuals employed during 2002–2005 by employers based in western Pennsylvania. Data were provided by Highmark, Inc. (Pittsburgh and Camp Hill, PA). Rates were adjusted for age, gender, and employee share of health care costs. National industry measures of psychological distress, work stress, and physical activity at work were also compiled from other data sources. Results Rates for clinical depression in 55 industries ranged from 6.9 to 16.2 %, (population rate = 10.45 %). Industries with the highest rates tended to be those which, on the national level, require frequent or difficult interactions with the public or clients, and have high levels of stress and low levels of physical activity. Conclusions Additional research is needed to help identify industries with relatively high rates of depression in other regions and on the national level, and to determine whether these differences are due in part to specific work stress exposures and physical inactivity at work. Clinical significance Claims database analyses may provide a cost-effective way to identify priorities for depression treatment and prevention in the workplace. PMID:24907896
Practice databases and their uses in clinical research.
Tierney, W M; McDonald, C J
1991-04-01
A few large clinical information databases have been established within larger medical information systems. Although they are smaller than claims databases, these clinical databases offer several advantages: accurate and timely data, rich clinical detail, and continuous parameters (for example, vital signs and laboratory results). However, the nature of the data vary considerably, which affects the kinds of secondary analyses that can be performed. These databases have been used to investigate clinical epidemiology, risk assessment, post-marketing surveillance of drugs, practice variation, resource use, quality assurance, and decision analysis. In addition, practice databases can be used to identify subjects for prospective studies. Further methodologic developments are necessary to deal with the prevalent problems of missing data and various forms of bias if such databases are to grow and contribute valuable clinical information.

Administrative health care claims data are used for epidemiologic, health services, and outcomes cancer research and thus play a significant role in policy. Cancer stage, which is often a major driver of cost and clinical outcomes, is not typically included in claims data. Evaluate algorithms used in a dataset of cancer patients to identify patients with metastatic breast (BC), lung (LC), or colorectal (CRC) cancer using claims data. Clinical data on BC, LC, or CRC patients (between January 1, 2007 and March 31, 2010) were linked to a health care claims database. Inclusion required health plan enrollment ≥3 months before initial cancer diagnosis date. Algorithms were used in the claims database to identify patients' disease status, which was compared with physician-reported metastases. Generic and tumor-specific algorithms were evaluated using ICD-9 codes, varying diagnosis time frames, and including/excluding other tumors. Positive and negative predictive values, sensitivity, and specificity were assessed. The linked databases included 14,480 patients; of whom, 32%, 17%, and 14.2% had metastatic BC, LC, and CRC, respectively, at diagnosis and met inclusion criteria. Nontumor-specific algorithms had lower specificity than tumor-specific algorithms. Tumor-specific algorithms' sensitivity and specificity were 53% and 99% for BC, 55% and 85% for LC, and 59% and 98% for CRC, respectively. Algorithms to distinguish metastatic BC, LC, and CRC from locally advanced disease should use tumor-specific primary cancer codes with 2 claims for the specific primary cancer >30-42 days apart to reduce misclassification. These performed best overall in specificity, positive predictive values, and overall accuracy to identify metastatic cancer in a health care claims database.

Administrative claims databases provide a wealth of data for assessing the effect of treatments in clinical practice. Our aim was to propose methodology for real-world studies in multiple sclerosis (MS) using these databases. In three large US administrative claims databases: MarketScan, PharMetrics Plus and Department of Defense (DoD), patients with MS were selected using an algorithm identified in the published literature and refined for accuracy. Algorithms for detecting newly diagnosed ('incident') MS cases were also refined and tested. Methodology based on resource and treatment use was developed to differentiate between relapses with and without hospitalization. When various patient selection criteria were applied to the MarketScan database, an algorithm requiring two MS diagnoses at least 30 days apart was identified as the preferred method of selecting patient cohorts. Attempts to detect incident MS cases were confounded by the limited continuous enrollment of patients in these databases. Relapse detection algorithms identified similar proportions of patients in the MarketScan and PharMetrics Plus databases experiencing relapses with (2% in both databases) and without (15-20%) hospitalization in the 1 year follow-up period, providing findings in the range of those in the published literature. Additional validation of the algorithms proposed here would increase their credibility. The methods suggested in this study offer a good foundation for performing real-world research in MS using administrative claims databases, potentially allowing evidence from different studies to be compared and combined more systematically than in current research practice.

Purpose The purpose of this paper is to determine the characteristics of healthcare facilities that produce the most efficient inpatient orthopedic surgery using a large-scale medical claims database in Japan. Design/methodology/approach Reimbursement claims data were obtained from April 1 through September 30, 2014. Input-oriented Banker-Charnes-Cooper model of data envelopment analysis (DEA) was employed. The decision-making unit was defined as a healthcare facility where orthopedic surgery was performed. Inputs were defined as the length of stay, the number of beds, and the total costs of expensive surgical devices. Output was defined as total surgical fees for each surgery. Efficiency scores of healthcare facilities were compared among different categories of healthcare facilities. Findings The efficiency scores of healthcare facilities with a diagnosis-procedure combination (DPC) reimbursement were significantly lower than those without DPC ( p=0.0000). All the efficiency scores of clinics with beds were 1. Their efficiency scores were significantly higher than those of university hospitals, public hospitals, and other hospitals ( p=0.0000). Originality/value This is the first research that applied DEA for orthopedic surgery in Japan. The healthcare facilities with DPC reimbursement were less efficient than those without DPC. The clinics with beds were the most efficient among all types of management bodies of healthcare facilities.

The purpose of this study was to identify patterns of admission, discharge, and readmission between hospital and long-term care facility among a group of Florida long-term care facility residents with pressure ulcers whose care was paid for by Medicaid. A patient-specific, longitudinal claims history database was constructed from data provided by the Florida Department of Health and Rehabilitative Services. This database was used to determine and analyze hospital admissions for pressure ulcer care among Medicaid recipients cared for in a long-term care facility. Analysis of the data determined that more than half of the Medicaid-covered long-term care facility residents who formed the target study group (54.57%) had multiple hospital admissions associated with pressure ulcers. Pressure ulcer hospital admissions amounted to a program cost of $9.9 million.

Fenofibrate and statins reduced the risk of diabetic retinopathy (DR) related treatment in clinical trials. We aimed to determine whether lipid-lowering medication use reduce the risk of DR and its treatments in patients with type 2 diabetes using a real-world health claims database. This was an observational analysis using a nation-wide health claims database of the Japan Medical Data Center (JMDC). Type 2 diabetes was defined by the ICD-10 codes with glucose-lowering medication use. Lipid-lowering medication use at least one year was confirmed by the Anatomical Therapeutic Chemical Classification System. DR and diabetic macular edema (DME) were determined by ICD-10; DR related treatments were determined by health insurance claims. A propensity score for lipid-lowering medication use was estimated, and a doubly robust estimator using the inverse probability weighting model with regression adjustment was obtained to estimate odds ratios (OR) with 95% confidence interval (95%CI) for cumulative incidence of DR and its treatments over 3 years. There were 69,070 persons with type 2 diabetes at baseline. DR developed in 5,687 persons over 3 years. Lipid-lowering medication use was associated with decreased risk of incidence of DR (OR 0.772, 95%CI 0.720-0.827; p<0.001). Lipid-lowering medication use was also associated with decreased incidence of DME, any treatments for DR, laser photocoagulation, and vitrectomy in patients with DR at baseline. In a population of patients with type 2 diabetes with a variety of risk profile, lipid-lowering medication use reduced the risk of DR and its treatments of laser photocoagulation and vitrectomy.

Objective To explore trends in demographics, comorbidities, anti-diabetic drug usage, and healthcare utilization costs in patients with newly-diagnosed type 2 diabetes mellitus (T2DM) using a large US claims database. Methods For the years 2007 and 2012, Truven Health Marketscan Research Databases were used to identify adults with newly-diagnosed T2DM and continuous 12-month enrollment with prescription benefits. Variables examined included patient demographics, comorbidities, inpatient utilization patterns, healthcare costs (inpatient and outpatient), drug costs, and diabetes drug claim patterns. Results Despite an increase in the overall database population between 2007-2012, the incidence of newly-diagnosed T2DM decreased from 1.1% (2007) to 0.65% (2012). Hyperlipidemia and hypertension were the most common comorbidities and increased in prevalence from 2007 to 2012. In 2007, 48.3% of newly-diagnosed T2DM patients had no claims for diabetes medications, compared with 36.2% of patients in 2012. The use of a single oral anti-diabetic drug (OAD) was the most common diabetes medication-related claim (46.2% of patients in 2007; 56.7% of patients in 2012). Among OAD monotherapy users, metformin was the most commonly used and increased from 2007 (74.7% of OAD monotherapy users) to 2012 (90.8%). Decreases were observed for sulfonylureas (14.1% to 6.2%) and thiazolidinediones (7.3% to 0.6%). Insulin, predominantly basal insulin, was used by 3.9% of patients in 2007 and 5.3% of patients in 2012. Mean total annual healthcare costs increased from $13,744 in 2007 to $15,175 in 2012, driven largely by outpatient services, although costs in all individual categories of healthcare services (inpatient and outpatient) increased. Conversely, total drug costs per patient were lower in 2012 compared with 2007. Conclusions Despite a drop in the rate of newly-diagnosed T2DM from 2007 to 2012 in the US, increased total medical costs and comorbidities per individual patient suggest that the clinical and economic trends for T2DM are not declining.

Healthcare claims databases have been used in several studies to characterize the risk and burden of chemotherapy-induced febrile neutropenia (FN) and effectiveness of colony-stimulating factors against FN. The accuracy of methods previously used to identify FN in such databases has not been formally evaluated. Data comprised linked electronic medical records from Geisinger Health System and healthcare claims data from Geisinger Health Plan. Subjects were classified into subgroups based on whether or not they were hospitalized for FN per the presumptive "gold standard" (ANC <1.0×10(9)/L, and body temperature ≥38.3°C or receipt of antibiotics) and claims-based definition (diagnosis codes for neutropenia, fever, and/or infection). Accuracy was evaluated principally based on positive predictive value (PPV) and sensitivity. Among 357 study subjects, 82 (23%) met the gold standard for hospitalized FN. For the claims-based definition including diagnosis codes for neutropenia plus fever in any position (n=28), PPV was 100% and sensitivity was 34% (95% CI: 24-45). For the definition including neutropenia in the primary position (n=54), PPV was 87% (78-95) and sensitivity was 57% (46-68). For the definition including neutropenia in any position (n=71), PPV was 77% (68-87) and sensitivity was 67% (56-77). Patients hospitalized for chemotherapy-induced FN can be identified in healthcare claims databases--with an acceptable level of mis-classification--using diagnosis codes for neutropenia, or neutropenia plus fever.

Background Oxycodone controlled release (CR) and oxymorphone extended release (ER) are frequently prescribed long-acting opioids, which are approved for twice-daily dosing. The US Food and Drug Administration approved a reformulated crush-resistant version of oxycodone CR in April 2010. Objective To compare the daily average consumption (DACON) for oxycodone CR and for oxymorphone ER before and after the introduction of the reformulated, crush-resistant version of oxycodone CR. Methods This was a retrospective claims database analysis using pharmacy claims from the MarketScan database for the period from January 2010 through March 2011. The interrupted time series analysis was used to evaluate the impact of the introduction of reformulated oxycodone CR on the DACON of the 2 drugs—oxycodone CR and oxymorphone ER. The source of the databases included private-sector health data from more than 150 medium and large employers. All prescription claims containing oxycodone CR and oxymorphone ER dispensed to members from January 1, 2010, to March 31, 2011, were included in the analysis. Prescription claims containing duplicate National Drug Codes, missing member identification, invalid quantities or inaccurate days supply of either drug, and DACON values of <1 and >500 were removed. Results The database yielded 483,063 prescription claims for oxycodone CR and oxymorphone ER from January 1, 2010, to March 31, 2011. The final sample consisted of 411,404 oxycodone CR prescriptions (traditional and reformulated) dispensed to 85,150 members and 62,656 oxymorphone ER prescriptions dispensed to 11,931 members. Before the introduction of reformulated oxycodone CR, DACON values for the highest strength available for each of the 2 drugs were 0.51 tablets higher for oxycodone CR than for oxymorphone ER, with mean DACON values of 3.5 for oxycodone CR and 3.0 for oxymorphone ER (P <.001). The differences of mean DACON between the 2 drugs for all lower strengths were 0.46 tablets, with mean DACON values of 2.7 for oxycodone CR and 2.3 for oxymorphone ER (P <.001). After the introduction of the new formulation, the difference in mean DACON between the 2 drugs was slightly lower: 0.45 tablets for the highest-strength and 0.40 tablets for the lower-strength pairs. Regression analyses showed that the immediate and overall impact of the reformulation of oxycodone CR on the DACON of oxycodone CR was minimal, whereas no changes were seen in the DACON of oxymorphone ER. The estimated DACON for oxycodone CR decreased by 0.1 tablets, or 3.7% (P <.001), 6 months after the new formulation was introduced. Conclusion The mean DACON was 0.4 tablets per day higher for oxycodone CR compared with oxymorphone ER for all dosage strengths for the entire study period. After the introduction of the reformulated oxycodone CR, the DACON for this drug was slightly mitigated; however, there was a minimal impact on the mean differences between oxycodone CR and oxymorphone ER.

Flood damage prediction models are essential building blocks in flood risk assessments. Little research has been dedicated so far to damage of small-scale urban floods caused by heavy rainfall, while there is a need for reliable damage models for this flood type among insurers and water authorities. The aim of this paper is to investigate a wide range of damage-influencing factors and their relationships with rainfall-related damage, using decision tree analysis. For this, district-aggregated claim data from private property insurance companies in the Netherlands were analysed, for the period of 1998-2011. The databases include claims of water-related damage, for example, damages related to rainwater intrusion through roofs and pluvial flood water entering buildings at ground floor. Response variables being modelled are average claim size and claim frequency, per district per day. The set of predictors include rainfall-related variables derived from weather radar images, topographic variables from a digital terrain model, building-related variables and socioeconomic indicators of households. Analyses were made separately for property and content damage claim data. Results of decision tree analysis show that claim frequency is most strongly associated with maximum hourly rainfall intensity, followed by real estate value, ground floor area, household income, season (property data only), buildings age (property data only), ownership structure (content data only) and fraction of low-rise buildings (content data only). It was not possible to develop statistically acceptable trees for average claim size, which suggest that variability in average claim size is related to explanatory variables that cannot be defined at the district scale. Cross-validation results show that decision trees were able to predict 22-26% of variance in claim frequency, which is considerably better compared to results from global multiple regression models (11-18% of variance explained). Still, a large part of the variance in claim frequency is left unexplained, which is likely to be caused by variations in data at subdistrict scale and missing explanatory variables.

Voltage-gated sodium channels (VGSCs) are drug targets for the treatment of epilepsy. Recently, a decreased risk of cancer associated with sodium channel-blocking antiepileptic drugs (AEDs) has become a research focus of interest. The purpose of this study was to test the hypothesis that the use of sodium channel-blocking AEDs are inversely associated with cancer, using different methodologies, algorithms, and databases. A total of 65,146,507 drug-reaction pairs from the first quarter of 2004 through the end of 2013 were downloaded from the US Food and Drug Administration Adverse Event Reporting System. The reporting odds ratio (ROR) and information component (IC) were used to detect an inverse association between AEDs and cancer. Upper limits of the 95% confidence interval (CI) of < 1 and < 0 for the ROR and IC, respectively, signified inverse associations. Furthermore, using a claims database, which contains 3 million insured persons, an event sequence symmetry analysis (ESSA) was performed to identify an inverse association between AEDs and cancer over the period of January 2005 to May 2014. The upper limit of the 95% CI of adjusted sequence ratio (ASR) < 1 signified an inverse association. In the FAERS database analyses, significant inverse associations were found between sodium channel-blocking AEDs and individual cancers. In the claims database analyses, sodium channel-blocking AED use was inversely associated with diagnoses of colorectal cancer, lung cancer, gastric cancer, and hematological malignancies, with ASRs of 0.72 (95% CI: 0.60 - 0.86), 0.65 (0.51 - 0.81), 0.80 (0.65 - 0.98), and 0.50 (0.37 - 0.66), respectively. Positive associations between sodium channel-blocking AEDs and cancer were not found in the study. Multi-methodological approaches using different methodologies, algorithms, and databases suggest that sodium channel-blocking AED use is inversely associated with colorectal cancer, lung cancer, gastric cancer, and hematological malignancies.

Accuracy was evaluated principally based on positive predictive value (PPV) and sensitivity. Results Among 357 study subjects, 82 (23%) met the gold standard for hospitalized FN. For the claims-based definition including diagnosis codes for neutropenia plus fever in any position (n=28), PPV was 100% and sensitivity was 34% (95% CI: 24–45).

For the definition including neutropenia in any position (n=71), PPV was 77% (68–87) and sensitivity was 67% (56–77). Conclusions Patients hospitalized for chemotherapy-induced FN can be identified in healthcare claims databases--with an acceptable level of mis-classification--using diagnosis codes for neutropenia, or neutropenia plus fever.

In the National Health Service (NHS), clinical negligence claims and associated compensations are constantly rising. The aim of this study is to identify the size, trends, and causes of litigations claims in relation to esophagogastric (EG) cancer in the NHS. Data requests were submitted to the NHS Litigation Authority (NHSLA) for the period of January 2003 to December 2013. Data were reviewed, categorized clinically, and analyzed in terms of causes and costs behind claims. In this time period, there were 163 claims identified from the NHSLA database. Ninety-five (58.3%) claims were successful with a pay out of £6.25 million. An increasing overall claim frequency and success rate were found over the last few years. Majority of the claims were from gastric cancer 84 (88.4%). The commonest cause of complaint in successful claims was delay or failure in diagnosis (21.1%) and treatment (17.9%). There were only 10.5% successful intraoperative claims, of which 50% were due to unnecessary or additional procedures. The frequency and success rates of malpractice claims in EG cancer are rising. The failure or delay in diagnosing and treatment in EG malignancy are the common cause for successful litigation claims. The findings further reinforce the need to improve early diagnosis. © The Authors 2017. Published by Oxford University Press on behalf of International Society for Diseases of the Esophagus.

Wade, Rolin L; Patel, Jeetvan G; Hill, Jerrold W; De, Ajita P; Harrison, David J
2017-09-01
Nonadherence to statin medications is associated with increased risk of cardiovascular disease and poses a challenge to lipid management in patients who are at risk for atherosclerotic cardiovascular disease. Numerous studies have examined statin adherence based on administrative claims data; however, these data may underestimate statin use in patients who participate in generic drug discount programs or who have alternative coverage. To estimate the proportion of patients with missing statin claims in a claims database and determine how missing claims affect commonly used utilization metrics. This retrospective cohort study used pharmacy data from the PharMetrics Plus (P+) claims dataset linked to the IMS longitudinal pharmacy point-of-sale prescription database (LRx) from January 1, 2012, through December 31, 2014. Eligible patients were represented in the P+ and LRx datasets, had ≥1 claim for a statin (index claim) in either database, and had ≥ 24 months of continuous enrollment in P+. Patients were linked between P+ and LRx using a deterministic method. Duplicate claims between LRx and P+ were removed to produce a new dataset comprised of P+ claims augmented with LRx claims. Statin use was then compared between P+ and the augmented P+ dataset. Utilization metrics that were evaluated included percentage of patients with ≥ 1 missing statin claim over 12 months in P+; the number of patients misclassified as new users in P+; the number of patients misclassified as nonstatin users in P+; the change in 12-month medication possession ratio (MPR) and proportion of days covered (PDC) in P+; the comparison between P+ and LRx of classifications of statin treatment patterns (statin intensity and patients with treatment modifications); and the payment status for missing statin claims. Data from 965,785 patients with statin claims in P+ were analyzed (mean age 56.6 years; 57% male). In P+, 20.1% had ≥ 1 missing statin claim post-index; 13.7% were misclassified as nonstatin users; and 14.9% were misclassified as new statin users. MPR was higher in the augmented P+ dataset versus the P+ dataset alone for all patients (79.4% vs. 76.7%, P < 0.001) and new users (61.4% vs. 58.7%, P < 0.001). Similarly, mean PDC was higher in the P+ dataset augmented with LRx versus the P+ dataset alone for all patients (76.0% vs. 74.0%, P < 0.001) and new users (58.5% vs. 56.5%, P < 0.001). Most patients received moderate-intensity statins; few changes in dose, intensity, or discontinuation of statins were observed when the P+ dataset was augmented. The most common reasons for missing data were payment by an alternate third-party program (66.3%) and use of cash, coupon, or discount cards (18.7%). Augmenting commercial claims data with point-of-sale data provides a more accurate assessment of statin use than claims data alone.

The concept of evidence-based medicine (EBM) has promulgated among healthcare professionals in recent years, on the other hand, the problem of underuse of useful clinical evidence is coming to be important. This is called as evidence-practice gap. The major concern about evidence-practice gap is insufficient implementation of evidence-based effective treatment, however, the perspective can be extended to measures to improve drug safety and prevention of drug related adverse events. First, this article reviews the characteristics of the database of receipt (healthcare claims) and the usefulness for research purpose of pharmacoepidemiology. Second, as the real example of the study on evidence-practice gap by using the receipt database, the case of ergot-derived anti-Parkinson drugs, of which risk of valvulopathy has been identified, is introduced. The receipt analysis showed that more than 70% of Parkinson's disease patients prescribed with cabergoline or pergolide did not undergo echocardiography despite the revision of the product label recommendation. Afterwards, the issues of pharmaceutical risk management and risk communication will be discussed.
Predicting failure to return to work.
Mills, R
2012-08-01
The research question is: is it possible to predict, at the time of workers' compensation claim lodgement, which workers will have a prolonged return to work (RTW) outcome? This paper illustrates how a traditional analytic approach to the analysis of an existing large database can be insufficient to answer the research question, and suggests an alternative data management and analysis approach. This paper retrospectively analyses 9018 workers' compensation claims from two different workers' compensation jurisdictions in Australia (two data sets) over a 4-month period in 2007. De-identified data, submitted at the time of claim lodgement, were compared with RTW outcomes for up to 3 months. Analysis consisted of descriptive, parametric (analysis of variance and multiple regression), survival (proportional hazards) and data mining (partitioning) analysis. No significant associations were found on parametric analysis. Multiple associations were found between the predictor variables and RTW outcome on survival analysis, with marked differences being found between some sub-groups on partitioning--where diagnosis was found to be the strongest discriminator (particularly neck and shoulder injuries). There was a consistent trend for female gender to be associated with a prolonged RTW outcome. The supplied data were not sufficient to enable the development of a predictive model. If we want to predict early who will have a prolonged RTW in Australia, workers' compensation claim forms should be redesigned, data management improved and specialised analytic techniques used. © 2011 The Author.

Administrative claims and electronic health records are valuable resources for evaluating pharmaceutical effects during pregnancy. However, direct measures of gestational age are generally not available. Establishing a reliable approach to infer the duration and outcome of a pregnancy could improve pharmacovigilance activities. We developed and applied an algorithm to define pregnancy episodes in four observational databases: three US-based claims databases: Truven MarketScan® Commercial Claims and Encounters (CCAE), Truven MarketScan® Multi-state Medicaid (MDCD), and the Optum ClinFormatics® (Optum) database and one non-US database, the United Kingdom (UK) based Clinical Practice Research Datalink (CPRD). Pregnancy outcomes were classified as live births, stillbirths, abortions and ectopic pregnancies. Start dates were estimated using a derived hierarchy of available pregnancy markers, including records such as last menstrual period and nuchal ultrasound dates. Validation included clinical adjudication of 700 electronic Optum and CPRD pregnancy episode profiles to assess the operating characteristics of the algorithm, and a comparison of the algorithm’s Optum pregnancy start estimates to starts based on dates of assisted conception procedures. Distributions of pregnancy outcome types were similar across all four data sources and pregnancy episode lengths found were as expected for all outcomes, excepting term lengths in episodes that used amenorrhea and urine pregnancy tests for start estimation. Validation survey results found highest agreement between reviewer chosen and algorithm operating characteristics for questions assessing pregnancy status and accuracy of outcome category with 99–100% agreement for Optum and CPRD. Outcome date agreement within seven days in either direction ranged from 95–100%, while start date agreement within seven days in either direction ranged from 90–97%. In Optum validation sensitivity analysis, a total of 73% of algorithm estimated starts for live births were in agreement with fertility procedure estimated starts within two weeks in either direction; ectopic pregnancy 77%, stillbirth 47%, and abortion 36%. An algorithm to infer live birth and ectopic pregnancy episodes and outcomes can be applied to multiple observational databases with acceptable accuracy for further epidemiologic research. Less accuracy was found for start date estimations in stillbirth and abortion outcomes in our sensitivity analysis, which may be expected given the nature of the outcomes. PMID:29389968

This study describes a large database of closed medical professional liability (MPL) claims involving family physicians in the United States. The purpose of this report is to provide information for practicing family physicians that will be useful in improving the quality of care, thereby reducing the incidence of patient injury and the consequent frequency of MPL claims. The Physician Insurers Association of America (PIAA) established a registry of closed MPL claims in 1985. This registry contains data describing 239,756 closed claims in the United States through 2008. The registry is maintained for educational programs that are designed to improve quality of care and reduce patient injury MPL claims. We summarized this closed claims database. Of 239,756 closed claims, 27,556 (11.5%) involved family physicians. Of these 27,556 closed claims, 8797 (31.9%) resulted in a payment, and the average payment was $164,107. In the entire registry, 29.5% of closed claims were paid, and the average payment was $209,156. The most common allegation among family medicine closed claims was diagnostic error, and the most prevalent diagnosis was acute myocardial infarction, which represented 24.1% of closed claims with diagnostic errors. Diagnostic errors related to patients with breast cancer represented the next most common condition, accounting for 21.3% of closed claims with diagnostic errors. MPL issues are common and are important to all practicing family physicians. Knowledge of the details of liability claims should assist practicing family physicians in improving quality of care, reducing patient injury, and reducing the incidence of MPL claims.

We investigated the epidemiology of upper urinary tract stone disease in Taiwan using a nationwide, population based database. This study was based on the National Health Insurance Research Database of Taiwan, which contains data on all medical beneficiary claims from 22.72 million enrollees, accounting for almost 99% of the Taiwanese population. The Longitudinal Health Insurance Database 2005, a subset of the National Health Insurance Research Database, contains data on all medical benefit claims from 1997 through 2010 for a subset of 1 million beneficiaries randomly sampled from the 2005 enrollment file. For epidemiological analysis we selected subjects whose claims records included the diagnosis of upper urinary tract urolithiasis. The age adjusted rate of medical care visits for upper urinary tract urolithiasis decreased by 6.5% from 1,367/100,000 subjects in 1998 to 1,278/100,000 in 2010. There was a significantly decreasing trend during the 13-year period in visits from female and all subjects (r(2) = 0.86, p = 0.001 and r(2) = 0.52, p = 0.005, respectively). In contrast, an increasing trend was noted for male subjects (r(2) = 0.45, p = 0.012). The age adjusted prevalence in 2010 was 9.01%, 5.79% and 7.38% in male, female and all subjects, respectively. The overall recurrence rate at 1 and 5 years was 6.12% and 34.71%, respectively. Male subjects had a higher recurrence rate than female subjects. Our study provides important information on the epidemiology of upper urinary tract stone disease in Taiwan, helping to quantify the burden of urolithiasis and establish strategies to decrease the risk of urolithiasis.

Mortality and complications of acute myocardial infarction (AMI) in France have declined over the last twenty years, but still remain high. Practice guidelines recommend secondary prevention measures to reduce these. Insurance claims databases can be used to assess the management of post MI and other cardiovascular outcomes in everyday practice. A cohort study was performed in a 1/97 representative sample of the French nationwide claims and hospitalisation database (EGB database). All adults with a documented hospitalisation for MI between 2007 and 2011 were included, and followed for three years. Data was extracted on demographics, the index admission, reimbursed medication, comorbidities, post-MI events and death. During the study period, 1977 individuals hospitalised for an MI were identified, with a mean (±SD) age of 63.8 (±14.3) years, 65.8% were men, 82.4% had hypertension and 37.6% hypercholesterolaemia. The mean duration of hospitalisation was seven days and 8.3% of patients died during hospitalisation. After discharge, the majority of patients received secondary prevention with statins (92.2%), anti-platelet drugs (95.6%), beta-blockers (86.0%) and angiotensin converting enzyme inhibitors (71.4%). After three years of follow-up post-discharge, cumulative mortality was 20.5% [18.4%;22.5%] and the cumulative incidence of reinfarction and stroke/TIA were 4.7% [95% CI: 3.7%;5.7%] and 4.1% [3.1%;5.0%], respectively. Despite high use of secondary prevention at discharge, mortality and incidence of serious cardiovascular events following MI remain high. This underscores the need to improve secondary prevention.

To establish a baseline pattern of care across academic and community settings, it is important to examine the contemporary treatment of acromegaly. We characterized medical treatment patterns for acromegaly in the US to develop a basis for tracking concordance with guidelines. Acromegaly patients were identified in two commercial claims databases for this retrospective analysis. Study subjects had ≥2 medical claims with acromegaly (ICD-9-CM code 253.0) and ≥1 claim for pharmacotherapy (bromocriptine, cabergoline, octreotide SA, octreotide LAR, lanreotide, or pegvisomant) in the study timeframe (1 January 2002-31 December 2013). Patients were considered newly treated if they were continuously enrolled for ≥6 months before first observed treatment and had no claim for pharmacologic treatment during that time. Outcomes included various pharmacotherapies, including combination treatments, and differences between lines of therapy. A total of 3150 patients had ≥1 pharmacotherapy (mean age: 46.5 years; 50.1% were female); 1471 were newly treated. Somatostatin receptor ligands (SRLs) were the most common drug class used first line (57.2%); cabergoline (27.8%) was the most common treatment, followed by octreotide LAR (22.3%) and lanreotide (19.7%). SRLs were also the most commonly used second-line (42.8%) and third-line pharmacotherapies (43.9%), with combination therapy (23.2%) and octreotide LAR (19.8%) as the most commonly used treatments, respectively. This study, representing the largest claims-based analysis of acromegaly to date, used two databases across a 12 year period to examine complex treatment patterns in a difficult-to-study disease. Although wide variation in acromegaly treatment patterns exists in US clinical practice, in first-line, second-line, and third-line therapy, SRL was the most commonly used drug class. Drug combinations also varied considerably across lines of therapy. The switching between different monotherapies and varied use of drugs in combination may suggest an unmet need for alternative treatment options. Our claims-based technique of examining treatment patterns may be used for other rare diseases, although high censoring rates may be a challenge.

Pharmacoepidemiological research using administrative databases has become increasingly popular for chronic rhinosinusitis (CRS); however, without a validated case definition the cohort evaluated may be inaccurate resulting in biased and incorrect outcomes. The objective of this study was to develop and validate a generalizable administrative database case definition for CRS using International Classification of Diseases, 9th edition (ICD-9)-coded claims. A random sample of 100 patients with a guideline-based diagnosis of CRS and 100 control patients were selected and then linked to a Canadian physician claims database from March 31, 2010, to March 31, 2015. The proportion of CRS ICD-9-coded claims (473.x and 471.x) for each of these 200 patients were reviewed and the validity of 7 different ICD-9-based coding algorithms was evaluated. The CRS case definition of ≥2 claims with a CRS ICD-9 code (471.x or 473.x) within 2 years of the reference case provides a balanced validity with a sensitivity of 77% and specificity of 79%. Applying this CRS case definition to the claims database produced a CRS cohort of 51,000 patients with characteristics that were consistent with published demographics and rates of comorbid asthma, allergic rhinitis, and depression. This study has validated several coding algorithms; based on the results a case definition of ≥2 physician claims of CRS (ICD-9 of 471.x or 473.x) within 2 years provides an optimal level of validity. Future studies will need to validate this administrative case definition from different health system perspectives and using larger retrospective chart reviews from multiple providers. © 2016 ARS-AAOA, LLC.

Situational awareness errors may play an important role in the genesis of patient harm. The authors examined closed anesthesia malpractice claims for death or brain damage to determine the frequency and type of situational awareness errors. Surgical and procedural anesthesia death and brain damage claims in the Anesthesia Closed Claims Project database were analyzed. Situational awareness error was defined as failure to perceive relevant clinical information, failure to comprehend the meaning of available information, or failure to project, anticipate, or plan. Patient and case characteristics, primary damaging events, and anesthesia payments in claims with situational awareness errors were compared to other death and brain damage claims from 2002 to 2013. Anesthesiologist situational awareness errors contributed to death or brain damage in 198 of 266 claims (74%). Respiratory system damaging events were more common in claims with situational awareness errors (56%) than other claims (21%, P < 0.001). The most common specific respiratory events in error claims were inadequate oxygenation or ventilation (24%), difficult intubation (11%), and aspiration (10%). Payments were made in 85% of situational awareness error claims compared to 46% in other claims (P = 0.001), with no significant difference in payment size. Among 198 claims with anesthesia situational awareness error, perception errors were most common (42%), whereas comprehension errors (29%) and projection errors (29%) were relatively less common. Situational awareness error definitions were operationalized for reliable application to real-world anesthesia cases. Situational awareness errors may have contributed to catastrophic outcomes in three quarters of recent anesthesia malpractice claims.Situational awareness errors resulting in death or brain damage remain prevalent causes of malpractice claims in the 21st century.

The objective of this study was to evaluate differences in calories, nutrient content, overall healthfulness, and use of sweetener ingredients between products with and without sugar claims. Consumers assume products with sugar claims are healthier and lower in calories. It is therefore important claims be found on comparatively healthier items. This study is a cross-sectional analysis of the University of Toronto's 2013 Food Label Database. Subcategories where at least 5% of products (and n ≥ 5) carried a sugar claim were included (n = 3048). Differences in median calorie content, nutrient content, and overall healthfulness, using the Food Standards Australia/New Zealand Nutrient Profiling Scoring criterion, between products with and without sugar claims, were determined. Proportion of products with and without claims that had excess free sugar levels (≥10% of calories from free sugar) and that contained sweeteners was also determined. Almost half (48%) of products with sugar claims contained excess free sugar, and a greater proportion contained sweeteners than products without such claims (30% vs 5%, χ 2 = 338.6, p < 0.0001). Overall, products with sugar claims were "healthier" and had lower median calorie, free sugar, total sugar, and sodium contents than products without claims. At the subcategory level, reductions in free sugar contents were not always met with similar reductions in calorie contents. This study highlights concerns with regards to the nutritional composition of products bearing sugar claims. Findings can support educational messaging to assist consumer interpretation of sugar claims and can inform changes in nutrition policies, for example, permitting sugar claims only on products with calorie reductions and without excess free sugar.

Malpractice claims that arise during the perioperative care of patients receiving orthopaedic procedures will frequently involve both orthopaedic surgeons and anesthesiologists. The Anesthesia Closed Claims database contains anesthesia malpractice claim data that can be used to investigate patient safety events arising during the care of orthopaedic patients and can provide insight into the medicolegal liability shared by the two specialties. (1) How do orthopaedic anesthetic malpractice claims differ from other anesthesia claims with regard to patient and case characteristics, common events and injuries, and liability profile? (2) What are the characteristics of patients who had neuraxial hematomas after spinal and epidural anesthesia for orthopaedic procedures? (3) What are the characteristics of patients who had orthopaedic anesthesia malpractice claims for central ischemic neurologic injury occurring during shoulder surgery in the beach chair position? (4) What are the characteristics of patients who had malpractice claims for respiratory depression and respiratory arrests in the postoperative period? The Anesthesia Closed Claims Project database was the source of data for this study. This national database derives data from a panel of liability companies (national and regional) and includes closed malpractice claims against anesthesiologists representing > 30% of practicing anesthesiologists in the United States from all types of practice settings (hospital, surgery centers, and offices). Claims for damage to teeth or dentures are not included in the database. Patient characteristics, type of anesthesia, damaging events, outcomes, and liability characteristics of anesthesia malpractice claims for events occurring in the years 2000 to 2013 related to nonspine orthopaedic surgery (n = 475) were compared with claims related to other procedures (n = 1592) with p < 0.05 as the criterion for statistical significance and two-tailed tests. Odds ratios and their 95% confidence intervals were calculated for all comparisons. Three types of claims involving high-impact injuries in patients undergoing nonspine orthopaedic surgery were identified through database query for in-depth descriptive review: neuraxial hematoma (n = 10), central ischemic neurologic injury in the beach chair position (n = 9), and injuries caused by postoperative respiratory depression (n = 23). Nonspine orthopaedic anesthesia malpractice claims were more frequently associated with nerve injuries (125 of 475 [26%], odds ratio [OR] 2.12 [1.66-2.71]) and events arising from the use of regional anesthesia (125 of 475 [26%], OR 6.18 (4.59-8.32) than in malpractice claims in other areas of anesthesia malpractice (230 of 1592 [14%] and 87 of 1592 [6%], respectively, p < 0.001 for both comparisons). Ninety percent (nine of 10) of patients with claims for neuraxial hematomas were receiving anticoagulant medication and all had severe long-term injuries, most with a history of significant delay in diagnosis and treatment after first appearance of signs and symptoms. Central ischemic injuries occurring during orthopaedic surgery in the beach chair position did not occur solely in patients who would have been considered at high risk for ischemic stroke. Patients with malpractice claims for injuries resulting from postoperative respiratory depression events had undergone lower extremity procedures (20 of 23 [87%]) and most events (22 of 23 [96%]) occurred on the day of surgery or the first postoperative day. Nonspine orthopaedic anesthesia malpractice claims more frequently cited nerve injury and events arising from the use of regional anesthesia than other surgical anesthesia malpractice claims. This may reflect the frequency of regional anesthesia in orthopaedic cases rather than increased risk of injury associated with regional techniques. When neuraxial procedures and anticoagulation regimens are used concurrently, care pathways should emphasize clear lines of responsibility for coordination of care and early investigation of any unusual neurologic findings that might indicate neuraxial hematoma. We do not have a good understanding of the factors that render some patients vulnerable to the rare occurrence of intraoperative central ischemic injury in the beach chair position, but providers should carefully calculate cerebral perfusion pressure relative to measured blood pressure for patients in the upright position. Postoperative use of multiple opioids by different concurrent modes of administration warrant special precautions with consideration given to the provision of care in settings with enhanced respiratory monitoring. The limitations of retrospective closed claims database review prevent conclusions regarding causation. Nonetheless, the collection of relatively rare events with substantial clinical detail provides valuable data to generate hypotheses about causation with potential for future study to improve patient safety. Level III, therapeutic study.

The high number of negative opinions from the European Food Safety Authority (EFSA) to the requests for authorization of health claims is largely due to the design of human intervention studies, including the inappropriate choice of outcome variables (OVs) and of their methods of measurement (MMs). The present manuscript reports the results of an investigation aimed to collect, collate and critically analyse the information in relation to claimed effects, OVs and MMs, in the context of protection against oxidative damage and cardiovascular health compliant with Regulation 1924/2006. Claimed effects, OVs and the related MMs were collected from EFSA Guidance documents and applications for authorization of health claims under Articles 13.5 and 14. The OVs and their MMs were evaluated only if the claimed effect was sufficiently defined and was considered beneficial by EFSA. The collection, collation and critical analysis of the relevant scientific literature consisted in the definition of the keywords, the PubMed search strategies and the creation of databases of references. The critical analysis of the OVs and their MMs was performed on the basis of the literature review and was aimed at defining the appropriateness of OVs and MMs in the context of the specific claimed effects. The information provided in this document could serve to EFSA for the development of further guidance on the scientific requirements for health claims, as well as to the stakeholders for the proper design of human intervention studies aimed to substantiate such health claims.

Rainstorm damage caused by malfunctioning of urban drainage systems and water intrusion due to defects in the building envelope can be considerable. Little research on this topic focused on the collection of damage data, the understanding of damage mechanisms and the deepening of data analysis methods. In this paper, the relative contribution of different failure mechanisms to the occurrence of rainstorm damage are investigated, as well as the extent to which these mechanisms relate to weather variables. For a case study in Rotterdam, the Netherlands, a property level home insurance database of around 3100 water-related damage claims was analysed. Records include comprehensive transcripts of communication between insurer, insured and damage assessment experts, which allowed claims to be classified according to their actual damage cause. Results show that roof and wall leakage is the most frequent failure mechanism causing precipitation-related claims, followed by blocked roof gutters, melting snow and sewer flooding. Claims related to sewer flooding were less present in the data, but are associated with significantly larger claim sizes than claims in the majority class, i.e. roof and wall leakages. Rare events logistic regression analysis revealed that maximum rainfall intensity and rainfall volume are significant predictors for the occurrence probability of precipitation-related claims. Moreover, it was found that claims associated with rainfall intensities smaller than 7-8 mm in a 60 min window are mainly related to failures processes in the private domain, such as roof and wall leakages. For rainfall events that exceed the 7-8 mm h-1 threshold, failure of systems in the public domain, such as sewer systems, start to contribute considerably to the overall occurrence probability of claims. The communication transcripts, however, lacked information to be conclusive about to extent to which sewer-related claims were caused by overloading of sewer systems or failure of system components.

The objectives of this study were to investigate the agreement between medical history questionnaire data and claims data and to identify the factors that were associated with discrepancies between these data types. Data from self-reported questionnaires that assessed an individual's history of hypertension, diabetes mellitus, dyslipidemia, stroke, heart disease, and pulmonary tuberculosis were collected from a general health screening database for 2014. Data for these diseases were collected from a healthcare utilization claims database between 2009 and 2014. Overall agreement, sensitivity, specificity, and kappa values were calculated. Multiple logistic regression analysis was performed to identify factors associated with discrepancies and was adjusted for age, gender, insurance type, insurance contribution, residential area, and comorbidities. Agreement was highest between questionnaire data and claims data based on primary codes up to 1 year before the completion of self-reported questionnaires and was lowest for claims data based on primary and secondary codes up to 5 years before the completion of self-reported questionnaires. When comparing data based on primary codes up to 1 year before the completion of self-reported questionnaires, the overall agreement, sensitivity, specificity, and kappa values ranged from 93.2 to 98.8%, 26.2 to 84.3%, 95.7 to 99.6%, and 0.09 to 0.78, respectively. Agreement was excellent for hypertension and diabetes, fair to good for stroke and heart disease, and poor for pulmonary tuberculosis and dyslipidemia. Women, younger individuals, and employed individuals were most likely to under-report disease. Detailed patient characteristics that had an impact on information bias were identified through the differing levels of agreement.

People are frequently confronted with untrustworthy claims about the effects of treatments. Uncritical acceptance of these claims can lead to poor, and sometimes dangerous, treatment decisions, and wasted time and money. Resources to help people learn to think critically about treatment claims are scarce, and they are widely scattered. Furthermore, very few learning-resources have been assessed to see if they improve knowledge and behavior. Our objectives were to develop the Critical thinking and Appraisal Resource Library (CARL). This library was to be in the form of a database containing learning resources for those who are responsible for encouraging critical thinking about treatment claims, and was to be made available online. We wished to include resources for groups we identified as 'intermediaries' of knowledge, i.e. teachers of schoolchildren, undergraduates and graduates, for example those teaching evidence-based medicine, or those communicating treatment claims to the public. In selecting resources, we wished to draw particular attention to those resources that had been formally evaluated, for example, by the creators of the resource or independent research groups. CARL was populated with learning-resources identified from a variety of sources-two previously developed but unmaintained inventories; systematic reviews of learning-interventions; online and database searches; and recommendations by members of the project group and its advisors. The learning-resources in CARL were organised by 'Key Concepts' needed to judge the trustworthiness of treatment claims, and were made available online by the James Lind Initiative in Testing Treatments interactive (TTi) English (www.testingtreatments.org/category/learning-resources).TTi English also incorporated the database of Key Concepts and the Claim Evaluation Tools developed through the Informed Healthcare Choices (IHC) project (informedhealthchoices.org). We have created a database of resources called CARL, which currently contains over 500 open-access learning-resources in a variety of formats: text, audio, video, webpages, cartoons, and lesson materials. These are aimed primarily at 'Intermediaries', that is, 'teachers', 'communicators', 'advisors', 'researchers', as well as for independent 'learners'. The resources included in CARL are currently accessible at www.testingtreatments.org/category/learning-resources. We hope that ready access to CARL will help to promote the critical thinking about treatment claims, needed to help improve healthcare choices.

Background Routine cytomegalovirus (CMV) screening during pregnancy is not recommended in the United States and the extent to which it is performed is unknown. Using a medical claims database, we computed rates of CMV-specific testing among pregnant women. Methods We used medical claims from the 2009 Truven Health MarketScan® Commercial databases. We computed CMV-specific testing rates using CPT codes. Results We identified 77,773 pregnant women, of whom 1,668 (2%) had a claim for CMV-specific testing. CMV-specific testing was significantly associated with older age, Northeast or urban residence, and a diagnostic code for mononucleosis. We identified 44 women with a diagnostic code for mononucleosis, of whom 14% had CMV-specific testing. Conclusions Few pregnant women had CMV-specific testing, suggesting that screening for CMV infection during pregnancy is not commonly performed. In the absence of national surveillance for CMV infections during pregnancy, healthcare claims are a potential source for monitoring practices of CMV-specific testing. PMID:23198949

Korea's National Healthcare Program, the National Health Insurance Service (NHIS), a government-affiliated agency under the Korean Ministry of Health and Welfare, covers the entire Korean population. The NHIS supervises all medical services in Korea and establishes a systematic National Health Information database (DB). A health information DB system including all of the claims, medications, death information, and health check-ups, both in the general population and in patients with various diseases, is not common worldwide. On June 9, 2014, the NHIS signed a memorandum of understanding with the Korean Diabetes Association (KDA) to provide limited open access to its DB. By October 31, 2017, seven papers had been published through this collaborative research project. These studies were conducted to investigate the past and current status of type 2 diabetes mellitus and its complications and management in Korea. This review is a brief summary of the collaborative projects between the KDA and the NHIS over the last 3 years. According to the analysis, the national health check-up DB or claim DB were used, and the age category or study period were differentially applied. Copyright © 2018 Korean Diabetes Association.

The study objective is to compare the annual total medical and indirect costs of newly treated and untreated employees with multiple sclerosis (MS). A retrospective database analysis of employer medical, drug, and disability claims database (Ingenix Employer database, 1999-2005; 17 large US companies) was conducted for employees 18-64 years of age with > or =1 MS diagnosis after January 1, 2002. Employees with > or =1 MS disease-modifying drug (DMD) claim comprised the newly treated group; employees with MS but no DMD at any time comprised the untreated, comparison group. Index date was the day after the most recent claim (treated, DMD claim; untreated, MS claim) meeting the following requirements: continuous health coverage for 3 months before (baseline period) and 12 months after the index date (study period) and actively employed during baseline. Total medical costs and indirect (work loss) costs over the 1-year study period (2006 $US) were compared for DMD-treated and untreated MS employees, adjusting for baseline characteristics, including comorbidities. During the baseline, MS employees who became treated (n = 258) were younger (40.9 vs. 44.4 years, p < 0.0001) and had a higher proportion of women (72 vs. 62%, p = 0.007) than the untreated group of MS employees who never received DMD treatment (n = 322). The 3-month baseline MS-related medical costs were higher among treated MS employees ($2520 vs. $1012, p < 0.0001). There was a nonsignificant trend toward higher baseline non-MS-related medical costs in untreated versus treated MS employees. Risk-adjusted total annual medical costs ($4393 vs. $6187, p < 0.0001) and indirect costs ($2252 vs. $3053, p < 0.0001) were significantly lower for treated MS employees than for untreated MS employees. Initiation of MS disease-modifying drugs was associated with substantial significant medical and indirect savings for employees with MS. Study findings should be considered in the context of the study limitations (e.g., analytic focus on employees with at least 12-month follow-up; lack of clinical detail on MS severity).

Wallace, E; Lowry, J; Smith, S M; Fahey, T
2013-01-01
Objectives The aim of this systematic review was to examine the epidemiology of malpractice claims in primary care. Design A computerised systematic literature search was conducted. Studies were included if they reported original data (≥10 cases) pertinent to malpractice claims, were based in primary care and were published in the English language. Data were synthesised using a narrative approach. Setting Primary care. Participants Malpractice claimants. Primary outcome Malpractice claim (defined as a written demand for compensation for medical injury). We recorded: medical misadventure cited in claims, missed/delayed diagnoses cited in claims, outcome of claims, prevalence of claims and compensation awarded to claimants. Results Of the 7152 articles retrieved by electronic search, a total of 34 studies met the inclusion criteria and were included in the narrative analysis. Twenty-eight studies presented data from medical indemnity malpractice claims databases and six studies presented survey data. Fifteen studies were based in the USA, nine in the UK, seven in Australia, one in Canada and two in France. The commonest medical misadventure resulting in claims was failure to or delay in diagnosis, which represented 26–63% of all claims across included studies. Common missed or delayed diagnoses included cancer and myocardial infarction in adults and meningitis in children. Medication error represented the second commonest domain representing 5.6–20% of all claims across included studies. The prevalence of malpractice claims in primary care varied across countries. In the USA and Australia when compared with other clinical disciplines, general practice ranked in the top five specialties accounting for the most claims, representing 7.6–20% of all claims. However, the majority of claims were successfully defended. Conclusions This review of malpractice claims in primary care highlights diagnosis and medication error as areas to be prioritised in developing educational strategies and risk management systems.

Abstract The use of claims database to study lymphomas in real-life conditions is a crucial issue in the future. In this way, it is essential to develop validated algorithms for the identification of lymphomas in these databases. The aim of this study was to assess the validity of diagnosis codes in the French health insurance database to identify incident cases of lymphomas according to results of a regional cancer registry, as the gold standard. Between 2010 and 2013, incident lymphomas were identified in hospital data through 2 algorithms of selection. The results of the identification process and characteristics of incident lymphomas cases were compared with data from the Tarn Cancer Registry. Each algorithm's performance was assessed by estimating sensitivity, predictive positive value, specificity (SPE), and negative predictive value. During the period, the registry recorded 476 incident cases of lymphomas, of which 52 were Hodgkin lymphomas and 424 non-Hodgkin lymphomas. For corresponding area and period, algorithm 1 provides a number of incident cases close to the Registry, whereas algorithm 2 overestimated the number of incident cases by approximately 30%. Both algorithms were highly specific (SPE = 99.9%) but moderately sensitive. The comparative analysis illustrates that similar distribution and characteristics are observed in both sources. Given these findings, the use of claims database can be consider as a pertinent and powerful tool to conduct medico-economic or pharmacoepidemiological studies in lymphomas. PMID:29480830
Malpractice claims for endoscopy
Hernandez, Lyndon V; Klyve, Dominic; Regenbogen, Scott E
2013-01-01
AIM: To summarize the magnitude and time trends of endoscopy-related claims and to compare total malpractice indemnity according to specialty and procedure. METHODS: We obtained data from a comprehensive database of closed claims from a trade association of professional liability insurance carriers, representing over 60% of practicing United States physicians. Total payments by procedure and year were calculated, and were adjusted for inflation (using the Consumer Price Index) to 2008 dollars. Time series analysis was performed to assess changes in the total value of claims for each type of procedure over time. RESULTS: There were 1901 endoscopy-related closed claims against all providers from 1985 to 2008. The specialties include: internal medicine (n = 766), gastroenterology (n = 562), general surgery (n = 231), general and family practice (n = 101), colorectal surgery (n = 87), other specialties (n = 132), and unknown (n = 22). Colonoscopy represented the highest frequencies of closed claims (n = 788) and the highest total indemnities ($54 093 000). In terms of mean claims payment, endoscopic retrograde cholangiopancreatography (ERCP) ranked the highest ($374 794) per claim. Internists had the highest number of total claims (n = 766) and total claim payment ($70 730 101). Only total claim payments for colonoscopy and ERCP seem to have increased over time. Indeed, there was an average increase of 15.5% per year for colonoscopy and 21.9% per year for ERCP after adjusting for inflation. CONCLUSION: There appear to be differences in malpractice coverage costs among specialties and the type of endoscopic procedure. There is also evidence for secular trend in total claim payments, with colonoscopy and ERCP costs rising yearly even after adjusting for inflation. PMID:23596540
A Review of the Use of Medicare Claims Data in Plastic Surgery Outcomes Research
Mahmoudi, Elham; Kotsis, Sandra V.
2015-01-01
Summary: With a growing national emphasis in data transparency and reporting of public health data, it is essential for researchers to know more about Medicare claims data, the largest and most reliable source of health-care utilization and expenditure for individuals older than 65 years in the United States. This article provides an overview of Medicare claims data for plastic surgery outcomes research. We highlight essential information on various files included in Medicare claims data, strengths and limitations of the data, and ways to expand the use of existing data for research purposes. As of now, Medicare data are limited in providing adequate information regarding severity of diagnosed conditions, health status of individuals, and health outcomes after certain procedures. However, the data contain all health-care utilization and expenditures for services that are covered by Medicare Parts A, B, and D (inpatient, outpatient, ambulatory-based and physician-based services, and prescription drugs). Additionally, Medicare claims data can be used for longitudinal analysis of variations in utilization and cost of health-care services at the patient level and provider level. Linking Medicare claims data with other national databases and utilizing the ICD-10 coding system would further expand the use of these datasets in health services research. PMID:26579336
Failures to replicate blocking are surprising and informative-Reply to Soto (2018).

The blocking effect has inspired numerous associative learning theories and is widely cited in the literature. We recently reported a series of 15 experiments that failed to obtain a blocking effect in rodents. On the basis of those consistent failures, we claimed that there is a lack of insight into the boundary conditions for blocking. In his commentary, Soto (2018) argued that contemporary associative learning theory does provide a specific boundary condition for the occurrence of blocking, namely the use of same- versus different-modality stimuli. Given that in 10 of our 15 experiments same-modality stimuli were used, he claims that our failure to observe a blocking effect is unsurprising. We disagree with that claim, because of theoretical, empirical, and statistical problems with his analysis. We also address 2 other possible reasons for a lack of blocking that are referred to in Soto's (2018) analysis, related to generalization and salience, and dissect the potential importance of both. Although Soto's (2018) analyses raise a number of interesting points, we see more merit in an empirically guided analysis and call for empirical testing of boundary conditions on blocking.

The cost of adherence mismeasurement in serious mental illness: a claims-based analysis.

To quantify how adherence mismeasurement affects the estimated impact of adherence on inpatient costs among patients with serious mental illness (SMI). Proportion of days covered (PDC) is a common claims-based measure of medication adherence. Because PDC does not measure medication ingestion, however, it may inaccurately measure adherence. We derived a formula to correct the bias that occurs in adherence-utilization studies resulting from errors in claims-based measures of adherence. We conducted a literature review to identify the correlation between gold-standard and claims-based adherence measures. We derived a bias-correction methodology to address claims-based medication adherence measurement error. We then applied this methodology to a case study of patients with SMI who initiated atypical antipsychotics in 2 large claims databases. Our literature review identified 6 studies of interest. The 4 most relevant ones measured correlations between 0.38 and 0.91. Our preferred estimate implies that the effect of adherence on inpatient spending estimated from claims data would understate the true effect by a factor of 5.3, if there were no other sources of bias. Although our procedure corrects for measurement error, such error also may amplify or mitigate other potential biases. For instance, if adherent patients are healthier than nonadherent ones, measurement error makes the resulting bias worse. On the other hand, if adherent patients are sicker, measurement error mitigates the other bias. Measurement error due to claims-based adherence measures is worth addressing, alongside other more widely emphasized sources of bias in inference.
A Contemporary Medicolegal Analysis of Implanted Devices for Chronic Pain Management.
Abrecht, Christopher R; Greenberg, Penny; Song, Ellen; Urman, Richard D; Rathmell, James P
2017-04-01
Analysis of closed malpractice claims allows the study of rare but serious complications and likely results in improved patient safety by raising awareness of such complications. Clinical studies and closed claims analyses have previously reported on the common complications associated with intrathecal drug delivery systems (IDDS) and spinal cord stimulators (SCS). This study provides a contemporary analysis of claims from within the past 10 years. We performed a closed claims analysis for a period January 1, 2009 to December 31, 2013 for cases with pain medicine as the primary service. These cases were identified using the Controlled Risk Insurance Company (CRICO) Comparative Benchmarking System (CBS), a database containing more than 300,000 malpractice claims from more than 400 academic and community institutions, representing approximately 30% of malpractice cases in the United States. The clinical narratives, which included medical files, claims files, depositions, and expert witness testimony, were reviewed by the authors, as were the CRICO coded variables, which included algorithmically determined contributing factors to the patient injury. Intrathecal drug delivery systems represented 17 of the closed claims; spinal cord stimulators represented 11 of the closed claims. The most common chronic pain diagnoses for which a device was implanted included failed back surgery syndrome and spasticity. The average total incurred for pain medicine claims was $166,028. Damaging events included IDDS refill errors (eg, subcutaneous administration of medication, reprogramming errors), intraoperative nerve damage, and postoperative infection (eg, epidural abscess, meningitis). High-severity outcomes included nerve damage (eg, paraplegia) and death. Medium-severity outcomes included drug reactions (eg, respiratory arrest from opioid overdose) and the need for reoperation. For both IDDS and SCS, deficits in technical skill were the most common contributing factor to injury, followed by deficits in clinical judgment, communication, and documentation. Implanted devices used for pain management involve a significant risk of morbidity and mortality. Proper education of providers and patients is essential. Providers must acquire the technical skills required for the implantation and refilling of these devices and the clinical skills required for the identification and management of complications such as intrathecal granuloma. Proper patient selection and clear communication between the provider and the patient about these possible complications are of paramount importance.

Background The objective of this study was to characterize insulin use and examine factors associated with persistence to mealtime insulin among patients with type 2 diabetes (T2D) on stable basal insulin therapy initiating mealtime insulin therapy. Methods Insulin use among patients with T2D initiating mealtime insulin was investigated using Thomson Reuters MarketScan® research databases from July 2001 through September 2006. The first mealtime insulin claim preceded by 6 months with 2 claims for basal insulin was used as the index event. A total of 21 months of continuous health plan enrollment was required. Patients were required to have a second mealtime insulin claim during the 12-month follow-up period. Persistence measure 1 defined non-persistence as the presence of a 90-day gap in mealtime insulin claims, effective the date of the last claim prior to the gap. Persistence measure 2 required 1 claim per quarter to be persistent. Risk factors for non-persistence were assessed using logistic regression. Results Patients initiating mealtime insulin (n = 4752; 51% male, mean age = 60.3 years) primarily used vial/syringe (87%) and insulin analogs (60%). Patients filled a median of 2, 3, and 4 mealtime insulin claims at 3, 6, and 12 months, respectively, with a median time of 76 days between refills. According to measure 1, persistence to mealtime insulin was 40.7%, 30.2%, and 19.1% at 3, 6, and 12 months, respectively. Results for measure 2 were considerably higher: 74.3%, 55.3%, and 42.2% of patients were persistent at 3, 6, and 12 months, respectively. Initiating mealtime insulin with human insulin was a risk factor for non-persistence by both measures (OR < 0.80, p < 0.01). Additional predictors of non-persistence at 12 months included elderly age, increased insulin copayment, mental health comorbidity, and polypharmacy (p < 0.05 for all). Conclusions Mealtime insulin use and persistence were both considerably lower than expected, and were significantly lower for human insulin compared to analogs. PMID:21226935

Inquiry-based instruction in biology has been the focus of educational research conducted by Unnes biology department students in collaboration with their university supervisors. This study aimed to describe the methodological aspects, inquiry teaching methods critically, and to analyse the results claims, of the selected four student research reports, grounded in inquiry, based on the database of Unnes biology department 2014. Four experimental quantitative research of 16 were selected as research objects by purposive sampling technique. Data collected through documentation study was qualitatively analysed regarding methods used, quality of inquiry syntax, and finding claims. Findings showed that the student research was still the lack of relevant aspects of research methodology, namely in appropriate sampling procedures, limited validity tests of all research instruments, and the limited parametric statistic (t-test) not supported previously by data normality tests. Their consistent inquiry syntax supported the four mini-thesis claims that inquiry-based teaching influenced their dependent variables significantly. In other words, the findings indicated that positive claims of the research results were not fully supported by good research methods, and well-defined inquiry procedures implementation.

We performed a retrospective cohort study in South Korea to clarify the role of occupational exposure, especially to welding, in the etiology of Parkinson's disease (PD). We constructed a database of subjects classified into an exposure group (blue-collar workers) and a non-exposure group (white-collar workers) in two shipbuilding companies. Jobs of blue-collar workers were categorized into the first group of welding, the second group of fitting, grinding and finishing, cutting, and the other group. To determine new cases of PD during the follow-up period (1992-2003), we used the physician billing claims database of the National Health Insurance Corporation. For the detected PD patients in the physician billing claims database, a neurologist in our research team confirmed the appropriateness of each diagnosis by reviewing medical charts. Based on the review, we confirmed the numbers of new cases of PD and calculated the relative risk (RR) and the 95% confidence intervals (CI) by Cox regression analysis. In a backward selection procedure, 'age' was a significant independent variable but exposure was not. Furthermore, the RR in welders (high exposure group) was also insignificant and less than that in others (very low exposure group). This longitudinal study of shipbuilding workers supports our previous case-control studies suggesting that exposure to manganese does not increase the risk of PD.
Healthcare resource use in advanced prostate cancer patients treated with docetaxel.

Although the treatment of metastatic castrate-resistant prostate cancer (mCRPC) has improved with newer therapies, there is little understanding how these therapies have impacted resource use and associated expenditures; available estimates are dated. The current study examined contemporary healthcare utilization and associated costs for mCRPC patients and how these measures changed over time. This retrospective cohort analysis used medical and pharmaceutical insurance claims data from a large non-payer-owned integrated claims database of US commercial insurers. Amongst all patients with a prostate cancer diagnosis (n=256,464), those with ≥ 1 docetaxel claim (docetaxel cohort, n=3642) were identified as mCRPC patients. Within the docetaxel cohort, an additional 6-months follow-up cohort (n=2862) was identified, i.e., patients with at least 6 months of follow-up after the first docetaxel claim. Resource utilization and costs were identified for all-cause hospitalizations, emergency room (ER) visits, physician visits and ambulatory visits, and prostate cancer-related prescription treatments. Significant increases in the mean per-patient-per-month (PPPM) count for the docetaxel cohort were observed for all medical resources measured (hospitalizations and ER, physician, and ambulatory visits) in the post-docetaxel period compared with the pre-docetaxel period (p<0.0001); similar significant increases were observed for the 6-months follow-up cohort in the last 6 months (prior to lost to follow-up date) compared with the period preceding the last 6 months (p<0.0408 ambulatory visits, p<0.0001 all other resources). Total docetaxel cohort costs (mean [standard deviation]) rose from an average PPPM cost of US$2593 (3208) in the pre-docetaxel period to US$5847 (6990) in the post-docetaxel period (p<0.0001); each of the individual resources measured (hospitalization, all healthcare visits, and prescription costs) demonstrated significant increases (p<0.0001). Retrospective study design. This large database analysis showed a significant increase in use of healthcare resources and associated costs among mCRPC patients following first-line docetaxel treatment.

This report examines relationships between the acceptance of compensation claims, and employee and workplace characteristics for healthcare workers in British Columbia, Canada to determine suitability of using only accepted claims for occupational epidemiology research. A retrospective cohort of full-time healthcare workers was constructed from an active incident surveillance database. Incidents filed for compensation over a 1-year period were examined for initial claim decision within a 6-month window relative to sub-sector of employment, age, sex, seniority, occupation of workers, and injury category. Compensation costs and duration of time lost for initially accepted claims were also investigated. Multiple logistic regression models with generalised estimating equations (GEEs) were used to calculate adjusted relative odds (ARO) of claims decision accounting for confounding factors and clustering effects. Employees of three health regions in British Columbia filed 2274 work-related claims in a year, of which 1863 (82%) were initially accepted for compensation. Proportion of claims accepted was lowest in community care (79%) and corporate office settings (79%) and highest in long-term care settings (86%). Overall, 46% of claims resulting from allergy/irritation were accepted, in contrast to 98% acceptance of claims from cuts and puncture wounds. Licensed practical nurses had the lowest odds of claims not accepted compared with registered nurses (ARO (95% CI) = 0.55 (0.33 to 0.91)), whereas management/administrative staff had the highest odds (ARO = 2.91 (1.25 to 6.79)) of claims not accepted. A trend was observed with higher seniority of workers associated with lower odds of non-acceptance of claims. Analysis from British Columbia's healthcare sector suggests variation in workers' compensation acceptance exists across sub-sectors, occupations, seniority of workers, and injury categories. The patterns observed, however, were independent of age and sex of workers. Results suggest that when using workers' compensation datasets, local adjudication regulations and factors associated with acceptance of claims should be taken into consideration.

A challenge in the use of insurance claims databases for epidemiologic research is accurate identification and verification of medical conditions. This report describes the development and validation of claims-based algorithms to identify colonic ischemia, hospitalized complications of constipation, and irritable bowel syndrome (IBS). From the research claims databases of a large healthcare company, we selected at random 120 potential cases of IBS and 59 potential cases each of colonic ischemia and hospitalized complications of constipation. We sought the written medical records and were able to abstract 107, 57, and 51 records, respectively. We established a 'true' case status for each subject by applying standard clinical criteria to the available chart data. Comparing the insurance claims histories to the assigned case status, we iteratively developed, tested, and refined claims-based algorithms that would capture the diagnoses obtained from the medical records. We set goals of high specificity for colonic ischemia and hospitalized complications of constipation, and high sensitivity for IBS. The resulting algorithms substantially improved on the accuracy achievable from a naïve acceptance of the diagnostic codes attached to insurance claims. The specificities for colonic ischemia and serious complications of constipation were 87.2 and 92.7%, respectively, and the sensitivity for IBS was 98.9%.

The US Food and Drug Administration is considering an application for a biosimilar version of infliximab, which has been available in South Korea since November 2012. The aim of the present study was to examine the utilization patterns of both branded and biosimilar infliximab and other tumor necrosis factor (TNF) inhibitors in South Korea before and after the introduction of this biosimilar infliximab. Using claims data from April 2009 to March 2014 from the Korean Health Insurance Review and Assessment Service database, which includes the entire South Korean population, the number of claims for biosimilar infliximab was assessed. A segmented linear regression model was used to examine the utilization patterns of infliximab (the branded and biosimilar versions) and other TNF inhibitors (adalimumab and etanercept) before and after the introduction of the biosimilar infliximab. In total, 20,976 TNF inhibitor users were identified from the South Korean claims database, including 983 with a prescription claim for biosimilar infliximab. Among all of the claims for any version of infliximab, the proportion of biosimilar infliximab claims increased to 19% through March 2014. Before November 2012, each month there were 33 (95% confidence interval [95% CI] 32, 35) more infliximab claims, 44 (95% CI 40, 48) more etanercept claims, and 50 (95% CI 47, 53) more adalimumab claims. After November 2012, there were significant changes in the slopes for trend in usage, with additional increases in the use of branded and biosimilar infliximab (9 more claims per month, 95% CI 2, 17) and decreases in the use of etanercept (-52 claims per month, 95% CI -66, -38) and adalimumab (-21 claims per month, 95% CI -35, -6). During the first 15 months since its introduction in South Korea, one-fifth of all infliximab claims were for the biosimilar version. Introduction of biosimilar infliximab may affect the use of other TNF inhibitors, and the magnitude of change in usage will likely differ in other countries. © 2016, American College of Rheumatology.

Background For the pending National Claims Database in Japan, researchers will not have access to death information in the enrollment files. We developed and evaluated a claims-based definition of death. Methodology/Principal Findings We used healthcare claims and enrollment data between January 2005 and August 2009 for 195,193 beneficiaries aged 20 to 74 in 3 private health insurance unions. We developed claims-based definitions of death using discharge or disease status and Charlson comorbidity index (CCI). We calculated sensitivity, specificity and positive predictive values (PPVs) using the enrollment data as a gold standard in the overall population and subgroups divided by demographic and other factors. We also assessed bias and precision in two example studies where an outcome was death. The definition based on the combination of discharge/disease status and CCI provided moderate sensitivity (around 60%) and high specificity (99.99%) and high PPVs (94.8%). In most subgroups, sensitivity of the preferred definition was also around 60% but varied from 28 to 91%. In an example study comparing death rates between two anticancer drug classes, the claims-based definition provided valid and precise hazard ratios (HRs). In another example study comparing two classes of anti-depressants, the HR with the claims-based definition was biased and had lower precision than that with the gold standard definition. Conclusions/Significance The claims-based definitions of death developed in this study had high specificity and PPVs while sensitivity was around 60%. The definitions will be useful in future studies when used with attention to the possible fluctuation of sensitivity in some subpopulations. PMID:23741526

We examined the association between long work hours, assembly line work and stress-related diseases utilizing objective health and employment data from an employer's administrative databases. A North American automobile manufacturing company provided data for claims for sickness, accident and disability insurance (work absence of at least 4 days) for cardiovascular disease (CVD), hypertension and psychological disorders, employee demographics, and facility hours worked per year for 1996-2001. Age-adjusted claim rates and age-adjusted rate ratios were calculated using Poisson regression, except for comparisons between production and skilled trades workers owing to lack of age denominator data by job category. Associations between overtime hours and claim rates by facility were examined by Poisson regression and multi-level Poisson regression. Claims for hypertension, coronary heart disease, CVD, and psychological disorders were associated with facility overtime hours. We estimate that a facility with 10 more overtime hours per week than another facility would have 4.36 more claims for psychological disorders, 2.33 more claims for CVD, and 3.29 more claims for hypertension per 1,000 employees per year. Assembly plants had the highest rates of claims for most conditions. Production workers tended to have higher rates of claims than skilled trades workers. Data from an auto manufacturer's administrative databases suggest that autoworkers working long hours, and assembly-line workers relative to skilled trades workers or workers in non-assembly facilities, have a higher risk of hypertension, CVD, and psychological disorders. Occupational disease surveillance and disease prevention programs need to fully utilize such administrative data. Copyright © 2013 Wiley Periodicals, Inc.

Prices are a significant driver of health care cost in the United States. Existing research on the politics of health system reform has emphasized the limited nature of policy entrepreneurs' efforts at solving the problem of rising prices through direct regulation at the state level. Yet this literature fails to account for how change agents in the states gradually reconfigured the politics of prices, forging new, transparency-based policy instruments called all-payer claims databases (APCDs), which are designed to empower consumers, purchasers, and states to make informed market and policy choices. Drawing on pragmatist institutional theory, this article shows how APCDs emerged as the dominant model for reforming health care prices. While APCD advocates faced significant institutional barriers to policy change, we show how they reconfigured existing ideas, tactical repertoires, and legal-technical infrastructures to develop a politically and technologically robust reform. Our analysis has important implications for theories of how change agents overcome structural barriers to health reform. Copyright © 2017 by Duke University Press.

There is an increasing need for the development of approaches to measure quality, costs and resource utilization patterns among allogeneic hematopoietic cell transplant (HCT) patients. Administrative claims data provide an opportunity to examine service utilization and costs, particularly from the payer’s perspective. However, because administrative claims data are primarily designed for reimbursement purposes, challenges arise when using it for research. We use a case study with data derived from the 2007–2011 Truven Health MarketScan Research database to discuss opportunities and challenges for the use of administrative claims data to examine the costs and service utilization of allogeneic HCT and chemotherapy alone for patients with acute myeloid leukemia (AML). Starting with a cohort of 29,915 potentially eligible patients with a diagnosis of AML, we were able to identify 211 patients treated with HCT and 774 treated with chemotherapy only where we were sufficiently confident of the diagnosis and treatment path to allow analysis. Administrative claims data provide an avenue to meet the need for health care costs, resource utilization, and outcome information. However, when using these data, a balance between clinical knowledge and applied methods is critical to identifying a valid study cohort and accurate measures of costs and resource utilization.

ABSTRACT Purpose: Intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents including ranibizumab and aflibercept are used to treat patients with ocular disorders such as neovascular age-related macular degeneration (nAMD); however, the injections are associated with rare instances of severe ocular inflammation. This study compared severe ocular inflammation rates in patients treated with ranibizumab versus aflibercept. Methods: United States physician-level claims data covering an 18-month period for each therapy were analyzed. The primary analysis compared severe ocular inflammation event rates per 1000 injections. Sensitivity and subgroup analyses evaluated the impact of factors including intraocular surgery, intravitreal antibiotic administration, and previous intravitreal injections. Results: The analysis included 432,794 injection claims (ranibizumab n = 253,647, aflibercept n = 179,147); significantly, more unique severe ocular inflammation events occurred in patients receiving aflibercept than ranibizumab (1.06/1000 injections, 95% confidence interval [CI], 0.91–1.21, vs. 0.64/1000 injections, 95% CI 0.54–0.74; p < 0.0001). Comparable results were observed for analyses of patients who had undergone glaucoma or cataract surgeries, had antibiotic-associated endophthalmitis, had non-antibiotic-associated endophthalmitis, and were non-treatment-naive. In contrast, no significant differences in severe ocular inflammation claims were recorded in treatment-naive patients who had no record of anti-VEGF treatment in the 6 months preceding the index claim. No significant change occurred in the rate of severe ocular inflammation claims over time following ranibizumab treatment. Conclusions: Severe ocular inflammation was more frequent following intravitreal injection with aflibercept than with ranibizumab during routine clinical use in patients with nAMD. This highlights the importance of real-world, post-approval, observational monitoring of novel medicines, and may aid clinical decision-making, including choice of anti-VEGF agent. PMID:26855278

Rivaroxaban has been shown to have similar efficacy but less major bleeding than warfarin in randomized trials of patients experiencing venous thromboembolism (VTE). This report sought to assess healthcare costs up to 12-months following an index VTE in patients prescribed either rivaroxaban or warfarin. This study analyzed claims from the MarketScan Commercial Claims and Encounters Database from November 2011-July 2015. It selected adults newly-diagnosed with VTE (deep vein thrombosis [DVT] or pulmonary embolism [PE]) if they had an outpatient prescription claim for rivaroxaban or warfarin within 7-days of the index event. Warfarin users were 2:1 propensity-score matched to rivaroxaban users and followed until the end of insurance coverage, end of data availability or 12-months of follow-up. Total per patient healthcare costs, including inpatient, outpatient, and overall pharmacy costs, were compared using a multivariable generalized linear model. In total, 10,929 rivaroxaban patients were matched to 21,858 warfarin patients. Mean follow-up for rivaroxaban and warfarin patients was 317- and 321-days for those experiencing an index DVT, and 313- and 318-days for those with PE. Mean overall treatment costs per patient were lower for rivaroxaban vs warfarin users (-$1,116, p = .0016). This cost difference was driven by lower inpatient (-$622) and outpatient (-$1,156) treatment costs, and the higher pharmacy costs ($661) were, therefore, fully offset. Results were similar when analysis was restricted to DVT patients. No significant difference in total costs was observed in patients experiencing an index PE. Claims databases are subject to inaccuracies and missing data. Prescription claims may not fully reflect actual medication utilization. Despite propensity-score matching and regression, residual confounding cannot be excluded. Rivaroxaban was associated with significantly lower total per patient VTE treatment costs, despite higher pharmacy costs. These savings are the result of decreased inpatient and outpatient healthcare utilization costs associated with rivaroxaban.

Keratinocyte carcinoma (nonmelanoma skin cancer) accounts for substantial burden in terms of high incidence and health care costs but is excluded by most cancer registries in North America. Administrative health insurance claims databases offer an opportunity to identify these cancers using diagnosis and procedural codes submitted for reimbursement purposes. To apply recursive partitioning to derive and validate a claims-based algorithm for identifying keratinocyte carcinoma with high sensitivity and specificity. Retrospective study using population-based administrative databases linked to 602 371 pathology episodes from a community laboratory for adults residing in Ontario, Canada, from January 1, 1992, to December 31, 2009. The final analysis was completed in January 2016. We used recursive partitioning (classification trees) to derive an algorithm based on health insurance claims. The performance of the derived algorithm was compared with 5 prespecified algorithms and validated using an independent academic hospital clinic data set of 2082 patients seen in May and June 2011. Sensitivity, specificity, positive predictive value, and negative predictive value using the histopathological diagnosis as the criterion standard. We aimed to achieve maximal specificity, while maintaining greater than 80% sensitivity. Among 602 371 pathology episodes, 131 562 (21.8%) had a diagnosis of keratinocyte carcinoma. Our final derived algorithm outperformed the 5 simple prespecified algorithms and performed well in both community and hospital data sets in terms of sensitivity (82.6% and 84.9%, respectively), specificity (93.0% and 99.0%, respectively), positive predictive value (76.7% and 69.2%, respectively), and negative predictive value (95.0% and 99.6%, respectively). Algorithm performance did not vary substantially during the 18-year period. This algorithm offers a reliable mechanism for ascertaining keratinocyte carcinoma for epidemiological research in the absence of cancer registry data. Our findings also demonstrate the value of recursive partitioning in deriving valid claims-based algorithms.

Billions of dollars have been spent on the goal of making healthcare data available to clinicians and researchers in the hopes of improving healthcare and lowering costs. However, the problems of data governance, distribution, and accessibility remain challenges for the healthcare system to overcome. In this study, we discuss some of the issues around holding, reporting, and distributing data, including the newest "big data" challenge: making the data accessible to researchers and policy makers. This article presents a case study in "big healthcare data" involving the Health Care Cost Institute (HCCI). HCCI is a nonprofit, nonpartisan, independent research institute that serves as a voluntary repository of national commercial healthcare claims data. Governance of large healthcare databases is complicated by the data-holding model and further complicated by issues related to distribution to research teams. For multi-payer healthcare claims databases, the 2 most common models of data holding (mandatory and voluntary) have different data security requirements. Furthermore, data transport and accessibility may require technological investment. HCCI's efforts offer insights from which other data managers and healthcare leaders may benefit when contemplating a data collaborative.

The O'Neill Institute for National and Global Health Law at Georgetown University, the World Health Organization, and the Lawyers Collective have come together to develop a searchable Global Health and Human Rights Database that maps the intersection of health and human rights in judgments, international and regional instruments, and national constitutions. Where states long remained unaccountable for violations of health-related human rights, litigation has arisen as a central mechanism in an expanding movement to create rights-based accountability. Facilitated by the incorporation of international human rights standards in national law, this judicial enforcement has supported the implementation of rights-based claims, giving meaning to states' longstanding obligations to realize the highest attainable standard of health. Yet despite these advancements, there has been insufficient awareness of the international and domestic legal instruments enshrining health-related rights and little understanding of the scope and content of litigation upholding these rights. As this accountability movement evolves, the Global Health and Human Rights Database seeks to chart this burgeoning landscape of international instruments, national constitutions, and judgments for health-related rights. Employing international legal research to document and catalogue these three interconnected aspects of human rights for the public's health, the Database's categorization by human rights, health topics, and regional scope provides a comprehensive means of understanding health and human rights law. Through these categorizations, the Global Health and Human Rights Database serves as a basis for analogous legal reasoning across states to serve as precedents for future cases, for comparative legal analysis of similar health claims in different country contexts, and for empirical research to clarify the impact of human rights judgments on public health outcomes.

Musculoskeletal disorder costs and medical claim filing in the US retail trade sector.
Bhattacharya, Anasua; Leigh, J Paul
2011-01-01
The average costs of Musculoskeletal Disorder (MSD) and odds ratios for filing medical claims related to MSD were examined. The medical claims were identified by ICD 9 codes for four US Census regions within retail trade. Large private firms' medical claims data from Thomson Reuters Inc. MarketScan databases for the years 2003 through 2006 were used. Average costs were highest for claims related to lumbar region (ICD 9 Code: 724.02) and number of claims were largest for low back syndrome (ICD 9 Code: 724.2). Whereas the odds of filing an MSD claim did not vary greatly over time, average costs declined over time. The odds of filing claims rose with age and were higher for females and southerners than men and non-southerners. Total estimated national medical costs for MSDs within retail trade were $389 million (2007 USD).

To analyze medical costs and healthcare resource utilization (HRU) associated with everolimus-based therapy or chemotherapy among post-menopausal women with hormone-receptor-positive, human-epidermal-growth-factor-receptor-2-negative (HR+/HER2-) metastatic breast cancer (mBC). Patients with HR+/HER2- mBC who discontinued a non-steroidal aromatase inhibitor and began a new line of treatment with everolimus-based therapy or chemotherapy (index therapy/index date) between July 20, 2012 and April 30, 2014 were identified from two large claims databases. All-cause, BC-related, and adverse event (AE)-related medical costs (in 2014 USD) and all-cause HRU per patient per month (PPPM) were analyzed for both treatment groups across patients' first four lines of therapies for mBC. Adjusted differences in costs and HRU between the everolimus and chemotherapy treatment group were estimated pooling all lines and using multivariable generalized linear models, accounting for difference in patient characteristics. A total of 3298 patients were included: 902 everolimus-treated patients and 2636 chemotherapy-treated patients. Compared to chemotherapy, everolimus was associated with significantly lower all-cause (adjusted mean difference = $3455, p < 0.01) and BC-related ($2510, p < 0.01) total medical costs, with inpatient ($1344, p < 0.01) and outpatient costs ($1048, p < 0.01) as the main drivers for cost differences. Everolimus was also associated with significantly lower AE-related medical costs ($1730, p < 0.01), as well as significantly lower HRU (emergency room incidence rate ratio [IRR] = 0.83; inpatient IRR = 0.74; inpatient days IRR = 0.65; outpatient IRR = 0.71; BC-related outpatient IRR = 0.57; all p < 0.01). This retrospective claims database analysis of commercially-insured patients with HR+/HER2- mBC in the US showed that everolimus was associated with substantial all-cause, BC-related, and AE-related medical cost savings and less utilization of healthcare resources relative to chemotherapy.

Securing the airway is one of the most important responsibilities in anaesthesia. Injuries related to airway management can occur. Analysis from closed claims can help to identify patterns of injury, risk factors and areas for improvement. All claims to The Norwegian System of Compensation to Patients from 1 January 2001 to 31 December 2015 within the medical specialty of anaesthesiology were studied. Data were extracted from this database for patients and coded by airway management procedures. Of 400 claims for injuries related to airway management, 359 were classified as 'non-severe' and 41 as 'severe'. Of the severe cases, 37% of injuries occurred during emergency procedures. Eighty-one claims resulted in compensation, and 319 were rejected. A total of €1,505,344 was paid to the claimants during the period. Claims of dental damage contributed to a numerically important, but financially modest, proportion of claims. More than half of the severe cases were caused by failed intubation or a misplaced endotracheal tube. Anaesthesia procedures are not without risk, and injuries can occur when securing the airway. The most common injury was dental trauma. Clear patterns of airway management that resulted in injuries are not apparent from our data, but 37% of severe cases were related to emergency procedures which suggest the need for additional vigilance. Guidelines for difficult intubation situations are well established, but adherence to such guidelines varies. Good planning of every general anaesthesia should involve consideration of possible airway problems and assessment of pre-existing poor dentition. © 2017 The Acta Anaesthesiologica Scandinavica Foundation.

Aims This claims data-based study compares the intensity of diabetes care in community dwellers and nursing home residents with dementia. Methods Delivery of diabetes-related medical examinations (DRMEs) was compared via logistic regression in 1,604 community dwellers and 1,010 nursing home residents with dementia. The intra-individual effect of nursing home transfer was evaluated within mixed models. Results Delivery of DRMEs decreases with increasing care dependency, with more community-living individuals receiving DRMEs. Moreover, DRME provision decreases after nursing home transfer. Conclusion Dementia patients receive fewer DRMEs than recommended, especially in cases of higher care dependency and particularly in nursing homes. This suggests lacking awareness regarding the specific challenges of combined diabetes and dementia care. PMID:28413415

To propose a unifying set of definitions for prescription adherence research utilizing electronic health record prescribing databases, prescription dispensing databases, and pharmacy claims databases and to provide a conceptual framework to operationalize these definitions consistently across studies. We reviewed recent literature to identify definitions in electronic database studies of prescription-filling patterns for chronic oral medications. We then develop a conceptual model and propose standardized terminology and definitions to describe prescription-filling behavior from electronic databases. The conceptual model we propose defines 2 separate constructs: medication adherence and persistence. We define primary and secondary adherence as distinct subtypes of adherence. Metrics for estimating secondary adherence are discussed and critiqued, including a newer metric (New Prescription Medication Gap measure) that enables estimation of both primary and secondary adherence. Terminology currently used in prescription adherence research employing electronic databases lacks consistency. We propose a clear, consistent, broadly applicable conceptual model and terminology for such studies. The model and definitions facilitate research utilizing electronic medication prescribing, dispensing, and/or claims databases and encompasses the entire continuum of prescription-filling behavior. Employing conceptually clear and consistent terminology to define medication adherence and persistence will facilitate future comparative effectiveness research and meta-analytic studies that utilize electronic prescription and dispensing records.

Duration of oral antibiotic therapy in acne has not been widely studied. Recent guidelines suggest it should be limited to 3 to 6 months. We sought to compare the duration of oral antibiotic use with recent guidelines and determine the potential cost-savings related to shortened durations. This is a retrospective cohort study from the MarketScan Commercial Claims and Encounters database. Claims data were used to determine duration and costs of antibiotic therapy. The mean course duration was 129 days. The majority (93%) of courses were less than 9 months. Among the 31,634 courses, 18,280 (57.8%) did not include concomitant topical retinoid therapy. The mean (95% confidence interval) duration with and without topical retinoid use was 133 (131.5-134.7) days and 127 (125.4-127.9) days, respectively. The mean excess direct cost of antibiotic treatment for longer than 6 months was $580.99/person. Claims cannot be attributed to a specific diagnosis or provider. The database does not provide information on acne severity. Duration of antibiotic use is decreasing when compared with previous data. However, 5547 (17.53%) courses exceeded 6 months, highlighting an opportunity for reduced antibiotic use. If courses greater than 6 months were shortened to 6 months, savings would be $580.99/person.

Understanding background comorbidity rates in psoriasis can provide perspective for adverse events associated with new therapies. We sought to assess the extent of comorbidities in psoriasis patients by use of the Truven Health Analytics MarketScan database. MarketScan, comprising commercial claims representative of a large US-insured population, had 1.22 million patients with ≥1 claim with a psoriasis diagnosis between January 1, 2008, and December 31, 2014. Patients ≥18 years of age who had ≥2 health claims in any diagnosis field for psoriasis (International Classification of Diseases, 9th Revision, Clinical Modification 696.1) with a psoriasis diagnosis (index) date between July 1, 2008, and June 30, 2014, were included to allow follow-up observation time. Prevalence and incidence of 24 comorbidities were assessed in 469,097 psoriasis patients; the most common comorbidities were hyperlipidemia (45.64% and 30.83%, respectively), hypertension (42.19% and 24.19%), depression (17.91% and 12.68%), type 2 diabetes mellitus (17.45% and 8.44%), and obesity (14.38% and 11.57%). A limitation of the study was that only a certain insured population was represented. Comorbidity rates align with those described in the literature and support the concept that psoriasis patients have high rates of cardiometabolic comorbidities. This analysis highlights the potential utility of very large insurance databases for determining comorbidity prevalence in psoriasis, which may aid health care providers in managing psoriasis.

The objectives of this study were to quantify the proportion of US patients with newly diagnosed rheumatoid arthritis (RA) in whom disease-modifying antirheumatic drug (DMARD) therapy was initiated within 12 months following diagnosis, to determine mean time to initiation, to compare the characteristics of initiators versus noninitiators, and to identify factors associated with noninitiation. A retrospective study was conducted using claims from the databases of commercial managed care and Medicare supplemental managed care to identify patients with claims containing codes for RA dated January 1, 2004, through September 30, 2008. The percentage of patients with RA and a prescription for a DMARD within 12 months after the index date (initiators) was evaluated. The characteristics of DMARD initiators and noninitiators during the preindex period were compared, including demographic and clinical characteristics, health care resource utilization, and cost variables. The probability of DMARD initiation was determined using survival analysis. Multivariate analysis was performed to estimate mean time from diagnosis to DMARD initiation based on demographic and clinical variables. Of 26,911 patients with newly diagnosed RA identified in the database searches, 63% had been prescribed a DMARD within 12 months after diagnosis. DMARD initiators were significantly more likely to have had a rheumatologist visit and rheumatoid factor testing and were more likely to have received a corticosteroid and/or an NSAID (all, P < 0.001). DMARD initiators had significantly lower total costs ($10,534 vs $12,725, respectively) and pharmacy drug costs ($2438 vs $2822) over the preindex period compared with noninitiators (both, P < 0.001). Independent factors associated with a greater likelihood of DMARD initiation included a rheumatologist visit, rheumatoid factor testing, NSAID use, and corticosteroid use. Age ≥85 years and the presence of comorbidities were associated with a significantly lower likelihood of DMARD initiation. Among managed care enrollees in the present analysis, 37% of patients newly diagnosed with RA were not being treated with DMARDs in the first 12 months after diagnosis. Time to DMARD initiation plateaued after 90 days, suggesting that if a patient was not prescribed a DMARD soon after RA diagnosis, he or she was not likely to receive one.

Harmful medication errors, or preventable adverse drug events (ADEs), are a prominent quality and cost issue in healthcare. Injectable medications are important therapeutic agents, but they are associated with a greater potential for serious harm than oral medications. The national burden of preventable ADEs associated with inpatient injectable medications and the associated medical professional liability (MPL) costs have not been previously described in the literature. To quantify the economic burden of preventable ADEs related to inpatient injectable medications in the United States. Medical error data (MedMarx 2009-2011) were utilized to derive the distribution of errors by injectable medication types. Hospital data (Premier 2010-2011) identified the numbers and the types of injections per hospitalization. US payer claims (2009-2010 MarketScan Commercial and Medicare 5% Sample) were used to calculate the incremental cost of ADEs by payer and by diagnosis-related group (DRG). The incremental cost of ADEs was defined as inclusive of the time of inpatient admission and the following 4 months. Actuarial calculations, assumptions based on published literature, and DRG proportions from 17 state discharge databases were used to derive the probability of preventable ADEs per hospitalization and their annual costs. MPL costs were assessed from state- and national-level industry reports, premium rates, and from closed claims databases between 1990 and 2011. The 2010 American Hospital Association database was used for hospital-level statistics. All costs were adjusted to 2013 dollars. Based on this medication-level analysis of reported harmful errors and the frequency of inpatient administrations with actuarial projections, we estimate that preventable ADEs associated with injectable medications impact 1.2 million hospitalizations annually. Using a matched cohort analysis of healthcare claims as a basis for evaluating incremental costs, we estimate that inpatient preventable ADEs associated with injectable medications increase the annual US payer costs by $2.7 billion to $5.1 billion, averaging $600,000 in extra costs per hospital. Across categories of injectable drugs, insulin had the highest risk per administration for a preventable ADE, although errors in the higher-volume categories of anti-infective, narcotic/analgesic, anticoagulant/thrombolytic and anxiolytic/sedative injectable medications harmed more patients. Our analysis of liability claims estimates that MPL associated with injectable medications totals $300 million to $610 million annually, with an average cost of $72,000 per US hospital. The incremental healthcare and MPL costs of preventable ADEs resulting from inpatient injectable medications are substantial. The data in this study strongly support the clinical and business cases of investing in efforts to prevent errors related to injectable medications.

Noninfectious uveitis (NIU) is a collection of intraocular inflammatory disorders that may be associated with significant visual impairment. To our knowledge, few studies have investigated NIU prevalence overall or stratified by inflammation location, severity, presence of systemic conditions, age, or sex. To estimate NIU prevalence using a large, retrospective, administrative claims database. This analysis used the OptumHealth Reporting and Insights database to estimate 2012 NIU prevalence. Analysis was conducted in September 2016. The large administrative insurance claims database includes 14 million privately insured individuals in 69 self-insured companies spanning diverse industries. Included in the study were patients with NIU with 2 or more uveitis diagnoses on separate days in 2012 and continuous enrollment in a health plan for all of 2012 and categorized by inflammation site. We estimated overall NIU prevalence by inflammation site, severity, sex, and age. Patients with anterior NIU were categorized by the presence of systemic conditions. Of the approximately 4 million eligible adult patients, approximately 2.1 million were women, and of the 932 260 children, 475 481 were boys. The adult prevalence of NIU was 121 cases per 100 000 persons (95% CI, 117.5-124.3). The pediatric NIU prevalence was 29 cases per 100 000 (95% CI, 26.1-33.2). Anterior NIU accounted for 81% (3904 cases) of adult NIU cases (98 per 100 000; 95% CI, 94.7-100.9) and 75% (207 cases) of pediatric NIU cases (22 per 100 000; 95% CI, 19.3-25.4). The prevalences of noninfectious intermediate, posterior, and panuveitis were, for adults, 1 (95% CI, 0.8-1.5), 10 (95% CI, 9.4-11.5), and 12 (95% CI, 10.6-12.7) per 100 000, respectively, and for pediatric patients, 0 (95% CI, 0.1-1.1), 3 (95% CI, 1.8-4.1), and 4 (95% CI, 2.9-5.6) per 100 000, respectively. The prevalence of NIU increased with age and was higher among adult females than males. Application of these estimates to the US population suggests that NIU affected approximately 298 801 American adults (95% CI, 290 512-307 324) and 21 879 children (95% CI, 19 360-24 626) in 2015. The estimated prevalence of NIU was 121 cases per 100 000 for adults (95% CI, 117.5-124.3) and 29 per 100 000 for children (95% CI, 26.1-33.2). Prevalence was estimated using administrative claims from a commercially insured population, which may have a different prevalence than other segments of the US population. A better understanding of the prevalence of NIU will help to determine the number of patients affected.

Background Harmful medication errors, or preventable adverse drug events (ADEs), are a prominent quality and cost issue in healthcare. Injectable medications are important therapeutic agents, but they are associated with a greater potential for serious harm than oral medications. The national burden of preventable ADEs associated with inpatient injectable medications and the associated medical professional liability (MPL) costs have not been previously described in the literature. Objective To quantify the economic burden of preventable ADEs related to inpatient injectable medications in the United States. Methods Medical error data (MedMarx 2009–2011) were utilized to derive the distribution of errors by injectable medication types. Hospital data (Premier 2010–2011) identified the numbers and the types of injections per hospitalization. US payer claims (2009–2010 MarketScan Commercial and Medicare 5% Sample) were used to calculate the incremental cost of ADEs by payer and by diagnosis-related group (DRG). The incremental cost of ADEs was defined as inclusive of the time of inpatient admission and the following 4 months. Actuarial calculations, assumptions based on published literature, and DRG proportions from 17 state discharge databases were used to derive the probability of preventable ADEs per hospitalization and their annual costs. MPL costs were assessed from state- and national-level industry reports, premium rates, and from closed claims databases between 1990 and 2011. The 2010 American Hospital Association database was used for hospital-level statistics. All costs were adjusted to 2013 dollars. Results Based on this medication-level analysis of reported harmful errors and the frequency of inpatient administrations with actuarial projections, we estimate that preventable ADEs associated with injectable medications impact 1.2 million hospitalizations annually. Using a matched cohort analysis of healthcare claims as a basis for evaluating incremental costs, we estimate that inpatient preventable ADEs associated with injectable medications increase the annual US payer costs by $2.7 billion to $5.1 billion, averaging $600,000 in extra costs per hospital. Across categories of injectable drugs, insulin had the highest risk per administration for a preventable ADE, although errors in the higher-volume categories of anti-infective, narcotic/analgesic, anticoagulant/thrombolytic and anxiolytic/sedative injectable medications harmed more patients. Our analysis of liability claims estimates that MPL associated with injectable medications totals $300 million to $610 million annually, with an average cost of $72,000 per US hospital. Conclusion The incremental healthcare and MPL costs of preventable ADEs resulting from inpatient injectable medications are substantial. The data in this study strongly support the clinical and business cases of investing in efforts to prevent errors related to injectable medications. PMID:24991335

Jaramillo and Destouni claim that freshwater consumption is beyond the planetary boundary, based on high estimates of water cycle components, different definitions of water consumption, and extrapolation from a single case study. The difference from our analysis, based on mainstream assessments of global water consumption, highlights the need for clearer definitions of water cycle components and improved models and databases.

This study was the first of its kind to analyze the finance protection in New Rural Cooperative Medical Scheme in China using a claim database analysis. A claim database analysis of all hospitalizations reimbursed from the New Rural Cooperative Medical Scheme between January 2005 and December 2008 in Panyu district of Guangzhou covering 108,414 discharges was conducted to identify the difference in real reimbursement rate among 5 hospitalization cost categories by sex, age, and hospital type and to investigate the distributions of hospital-type choices among age and hospitalization cost categories. The share of total cost reimbursed was only 34% on average, and increased with age but decreased with higher hospitalization cost, undermining catastrophic coverage. Older people were more likely to be hospitalized at lower level hospitals with higher reimbursement rate. The mean cost per hospitalization and average length of stay increased whereas the real reimbursement rate decreased with hospital level among the top 4 diseases with the same ICD-10 diagnostic code (3-digit level) for each age group. Providing better protection against costly medical needs will require shifting the balance of objectives somewhat away from cost control toward more generous reimbursement, expanding the list of treatments that the insurance will cover, or some other policy to provide adequate care at lower cost facilities where more of the cost is now covered.
Malpractice in distal radius fracture management: an analysis of closed claims.
DeNoble, Peter H; Marshall, Astrid C; Barron, O Alton; Catalano, Louis W; Glickel, Steven Z
2014-08-01
Distal radius fractures comprise the majority of hand- and wrist-related malpractice claims. We hypothesized that a majority of lawsuits would be for malunions resulting from nonsurgical treatment. Additional goals of this study were to quantify costs associated with claims, determine independent risk factors for making an indemnity payment, and illustrate trends over time. Seventy closed malpractice claims filed for alleged negligent treatment of distal radius fractures by orthopedic surgeons insured by the largest medical professional liability insurer in New York State (NYS) from 1981 to 2005 were reviewed. We separately reviewed defendants' personal closed malpractice claim histories from 1975 to 2011. Overall incidence of malpractice claims among distal radius fractures treated in NYS was calculated using the NYS Statewide Planning and Research Cooperative System database and the 2008 American Academy of Orthopedic Surgeons census data. The overall incidence of malpractice claims for distal radius fracture management was low. Malunion was the most common complaint across claims regardless of treatment type. Claims for surgically treated fractures increased over time. A majority of claims documented poor doctor-patient relationships. Male plaintiffs in this group were significantly older than males treated for distal radius fractures in NYS. Most defendants had a history of multiple malpractice suits, all were male, and only a small percentage were fellowship-trained in hand surgery. Defendants lacking American Board of Orthopedic Surgery certification were significantly more likely to make indemnity payments. Thirty-eight of 70 cases resulted in an indemnity payment. Malunion and poor doctor-patient relationships are the major features of malpractice litigation involving distal radius fracture management. Older defendant age and lack of American Board of Orthopedic Surgery certification increase the likelihood of making an indemnity payment. Economic and decision analyses II.

SCRIPDB: a portal for easy access to syntheses, chemicals and reactions in patents
Heifets, Abraham; Jurisica, Igor
2012-01-01
The patent literature is a rich catalog of biologically relevant chemicals; many public and commercial molecular databases contain the structures disclosed in patent claims. However, patents are an equally rich source of metadata about bioactive molecules, including mechanism of action, disease class, homologous experimental series, structural alternatives, or the synthetic pathways used to produce molecules of interest. Unfortunately, this metadata is discarded when chemical structures are deposited separately in databases. SCRIPDB is a chemical structure database designed to make this metadata accessible. SCRIPDB provides the full original patent text, reactions and relationships described within any individual patent, in addition to the molecular files common to structural databases. We discuss how such information is valuable in medical text mining, chemical image analysis, reaction extraction and in silico pharmaceutical lead optimization. SCRIPDB may be searched by exact chemical structure, substructure or molecular similarity and the results may be restricted to patents describing synthetic routes. SCRIPDB is available at http://dcv.uhnres.utoronto.ca/SCRIPDB. PMID:22067445

To determine the prevalence and duration of social security benefits (SSBs) claims to registered workers with asthma in Brazil by the Brazilian National Institute of Social Security in 2008. This was a retrospective, descriptive study, based on information obtained from the Brazilian Unified Benefit System database, on the number of SSB claims granted to registered workers with asthma in 2008. The reference population was the monthly mean number of workers registered in the Brazilian Social Registry Database in 2008. The variables studied were type of economic activity, gender, age, and type/duration of the SSB claim. The relationship between work and asthma was evaluated by the prevalence ratio (PR) between work-related and non-work-related SSB claims for asthma. In 2008, 2,483 SSB claims were granted for asthma, with a prevalence of 7.5 allowances per 100,000 registered workers. The prevalence was higher among females than among males (PR = 2.1 between the sexes). Workers > 40 years of age were 2.5 times more likely to be granted an SSB claim for asthma than were younger workers. The prevalence was highest among workers engaged in the following types of economic activity: sewage, wood and wood product manufacturing, and furniture manufacturing (78.8, 22.4, and 22.2 claims/100,000 registered workers, respectively). The median (interquartile range) duration of SSB claims for asthma was 49 (28-87) days. Asthma is a major cause of sick leave, and its etiology has a strong occupational component. This has a major impact on employers, employees, and the social security system. Being female, being > 40 years of age, and working in the areas of urban sanitation/sewage, wood and wood product manufacturing, and furniture manufacturing increase the chance of sick leave due to asthma.

To determine healthcare claim patterns associated using nonsteroidal anti-inflammatory drugs (NSAIDs) for rheumatoid arthritis (RA). The CADEUS study randomly identified NSAID users within the French health insurance database. One-year claims data were extracted, and NSAID indication was obtained from prescribers. Logistic regression was used in a development sample to identify claim patterns predictive of RA and models applied to a validation sample. Analyses were stratified on the dispensation of immunosuppressive agents or specific antirheumatism treatment, and the area under the receiver operating characteristic curve was used to estimate discriminant power. NSAID indication was provided for 26,259 of the 45,217 patients included in the CADEUS cohort; it was RA for 956 patients. Two models were constructed using the development sample (n = 13,143), stratifying on the dispensation of an immunosuppressive agent or specific antirheumatism treatment. Discriminant power was high for both models (AUC > 0.80) and was not statistically different from that found when applied to the validation sample (n = 13,116). The models derived from this study may help to identify patients prescribed NSAIDs who are likely to have RA in claims databases without medical data such as treatment indication.

To identify and assess billing, procedural, or diagnosis code, or pharmacy claim-based algorithms used to identify acute bronchospasm in administrative and claims databases. We searched the MEDLINE database from 1991 to September 2012 using controlled vocabulary and key terms related to bronchospasm, wheeze and acute asthma. We also searched the reference lists of included studies. Two investigators independently assessed the full text of studies against pre-determined inclusion criteria. Two reviewers independently extracted data regarding participant and algorithm characteristics. Our searches identified 677 citations of which 38 met our inclusion criteria. In these 38 studies, the most commonly used ICD-9 code was 493.x. Only 3 studies reported any validation methods for the identification of bronchospasm, wheeze or acute asthma in administrative and claims databases; all were among pediatric populations and only 2 offered any validation statistics. Some of the outcome definitions utilized were heterogeneous and included other disease based diagnoses, such as bronchiolitis and pneumonia, which are typically of an infectious etiology. One study offered the validation of algorithms utilizing Emergency Department triage chief complaint codes to diagnose acute asthma exacerbations with ICD-9 786.07 (wheezing) revealing the highest sensitivity (56%), specificity (97%), PPV (93.5%) and NPV (76%). There is a paucity of studies reporting rigorous methods to validate algorithms for the identification of bronchospasm in administrative data. The scant validated data available are limited in their generalizability to broad-based populations. Copyright © 2013 Elsevier Ltd. All rights reserved.
Mapping the literature of transcultural nursing*
Murphy, Sharon C.
2006-01-01
Overview: No bibliometric studies of the literature of the field of transcultural nursing have been published. This paper describes a citation analysis as part of the project undertaken by the Nursing and Allied Health Resources Section of the Medical Library Association to map the literature of nursing. Objective: The purpose of this study was to identify the core literature and determine which databases provided the most complete access to the transcultural nursing literature. Methods: Cited references from essential source journals were analyzed for a three-year period. Eight major databases were compared for indexing coverage of the identified core list of journals. Results: This study identifies 138 core journals. Transcultural nursing relies on journal literature from associated health sciences fields in addition to nursing. Books provide an important format. Nearly all cited references were from the previous 18 years. In comparing indexing coverage among 8 major databases, 3 databases rose to the top. Conclusions: No single database can claim comprehensive indexing coverage for this broad field. It is essential to search multiple databases. Based on this study, PubMed/MEDLINE, Social Sciences Citation Index, and CINAHL provide the best coverage. Collections supporting transcultural nursing require robust access to literature beyond nursing publications. PMID:16710461

Post-marketing safety studies of medicines often rely on administrative claims databases to identify adverse outcomes following drug exposure. Valid ascertainment of outcomes is essential for accurate results. We aim to quantify the validity of diagnostic codes for serious hypocalcemia and dermatologic adverse events from insurance claims data among women with postmenopausal osteoporosis (PMO). We identified potential cases of serious hypocalcemia and dermatologic events through ICD-9 diagnosis codes among women with PMO within claims from a large US healthcare insurer (June 2005-May 2010). A physician adjudicated potential hypocalcemic and dermatologic events identified from the primary position on emergency department (ED) or inpatient claims through medical record review. Positive predictive values (PPVs) and 95% confidence intervals (CIs) quantified the fraction of potential cases that were confirmed. Among 165,729 patients with PMO, medical charts were obtained for 40 of 55 (73%) potential hypocalcemia cases; 16 were confirmed (PPV 40%, 95% CI 25-57%). The PPV was higher for ED than inpatient claims (82 vs. 24%). Among 265 potential dermatologic events (primarily urticaria or rash), we obtained 184 (69%) charts and confirmed 128 (PPV 70%, 95% CI 62-76%). The PPV was higher for ED than inpatient claims (77 vs. 39%). Diagnostic codes for hypocalcemia and dermatologic events may be sufficient to identify events giving rise to emergency care, but are less accurate for identifying events within hospitalizations.

Objectives To determine in a large claims database the healthcare utilization and costs associated with treatment of alcohol dependence with medications vs no medication and across 4 US Food and Drug Administration (FDA)–approved medications. Study Design Claims database analysis. Methods Eligible adults with alcohol dependence claims (n = 27,135) were identified in a commercial database (MarketScan; Thomson Reuters Inc, Chicago, Illinois). Following propensity score–based matching and inverse probability weighting on demographic, clinical, and healthcare utilization variables, patients who had used an FDA-approved medication for alcohol dependence (n = 2977) were compared with patients who had not (n = 2977). Patients treated with oral naltrexone hydrochloride (n = 2064), oral disulfiram (n = 2076), oral acamprosate calcium (n = 5068), or extended-release injectable naltrexone (naltrexone XR) (n = 295) were also compared for 6-month utilization rates of alcoholism medication, inpatient detoxification days, alcoholism-related inpatient days, and outpatient services, as well as inpatient charges. Results Patients who received alcoholism medications had fewer inpatient detoxification days (706 vs 1163 days per 1000 patients, P <.001), alcoholism-related inpatient days (650 vs 1086 days, P <.001), and alcoholism-related emergency department visits (127 vs 171, P = .005). Among 4 medications, the use of naltrexone XR was associated with fewer inpatient detoxification days (224 days per 1000 patients) than the use of oral naltrexone (552 days, P = .001), disulfiram (403 days, P = .049), or acamprosate (525 days, P <.001). The group receiving naltrexone XR also had fewer alcoholism-related inpatient days than the groups receiving disulfiram or acamprosate. More patients in the naltrexone XR group had an outpatient substance abuse visit compared with patients in the oral alcoholism medication groups. Conclusion Patients who received an alcoholism medication had lower healthcare utilization than patients who did not. Naltrexone XR showed an advantage over oral medications in healthcare utilization and costs. PMID:21348558

Using diagnosis code-based algorithms is the primary method of identifying patient cohorts for retrospective studies; nevertheless, many databases lack reliable diagnosis code information. To develop precise algorithms based on medication claims/prescriber visits (MCs/PVs) to identify psoriasis (PsO) patients and psoriatic patients with arthritic conditions (PsO-AC), a proxy for psoriatic arthritis, in Canadian databases lacking diagnosis codes. Algorithms were developed using medications with narrow indication profiles in combination with prescriber specialty to define PsO and PsO-AC. For a 3-year study period from July 1, 2009, algorithms were validated using the PharMetrics Plus database, which contains both adjudicated medication claims and diagnosis codes. Positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity of the developed algorithms were assessed using diagnosis code as the reference standard. Chosen algorithms were then applied to Canadian drug databases to profile the algorithm-identified PsO and PsO-AC cohorts. In the selected database, 183,328 patients were identified for validation. The highest PPVs for PsO (85%) and PsO-AC (65%) occurred when a predictive algorithm of two or more MCs/PVs was compared with the reference standard of one or more diagnosis codes. NPV and specificity were high (99%-100%), whereas sensitivity was low (≤30%). Reducing the number of MCs/PVs or increasing diagnosis claims decreased the algorithms' PPVs. We have developed an MC/PV-based algorithm to identify PsO patients with a high degree of accuracy, but accuracy for PsO-AC requires further investigation. Such methods allow researchers to conduct retrospective studies in databases in which diagnosis codes are absent.

The aim of this study was to assess the clinical characteristics and trends in valganciclovir use among infants diagnosed with congenital cytomegalovirus (CMV) disease in the United States. We analyzed data from medical claims dated 2009-2015 from the Truven Health MarketScan ® Commercial Claims and Encounters and Medicaid databases. We identified infants with a live birth code in the first claim who were continuously enrolled for at least 45 days. Among infants diagnosed with congenital CMV disease, identified by an ICD-9-CM or ICD-10-CM code for congenital CMV infection or CMV disease within 45 days of birth, we assessed data from claims containing codes for any CMV-associated clinical condition within the same period, and data from claims for hearing loss and/or valganciclovir within the first 180 days of life. In the commercial and Medicaid databases, we identified 257 (2.5/10,000) and 445 (3.3/10,000) infants, respectively, diagnosed with congenital CMV disease, among whom 135 (53%) and 282 (63%) had ≥1 CMV-associated condition, 30 (12%) and 32 (7%) had hearing loss, and 41 (16%) and 78 (18%) had a claim for valganciclovir. Among infants with congenital CMV disease who had a claim for valganciclovir, 37 (90%) among commercially insured infants and 68 (87%) among Medicaid-insured infants had ≥1 CMV-associated condition and/or hearing loss. From 2009 to 2015, the percentages with a claim for valganciclovir increased from 0% to 29% among commercially insured infants and from 4% to 37% among Medicaid-insured infants (P < 0.0001). During 2009-2015, there was a strong upward trend in valganciclovir claims among insured infants who were diagnosed with congenital CMV disease, the majority of whom had CMV-associated conditions and/or hearing loss.

Looking a gift horse in the mouth: Evaluation of wide-field asteroid photometric surveys

It has recently become possible to do a photometric survey of many asteroids at once, rather than observing single asteroids one (or occasionally a couple) at a time. We evaluate two such surveys. Dermawan et al. (Dermawan et al. [2011]. Publ. Astron. Soc. Jpn. 63, S555-S576) observed one night on the Subaru 8.2 m telescope, and Masiero et al. (Masiero, J., Jedicke, R., Durech, J., Gwen, S., Denneau, L., Larsen, J. [2009]. Icarus 204, 145-171) observed six nights over 2 weeks with the 3.6 m CFHT. Dermawan claimed 83 rotation periods from 127 detected asteroids; Masiero et al. claimed 218 rotation periods from 828 detections. Both teams claim a number of super-fast rotators (P < 2.2 h) among main belt asteroids larger than 250 m diameter, some up to several km in diameter. This would imply that the spin rate distribution of main belt asteroids differs from like-sized NEAs, that there are larger super-fast rotators (monolithic asteroids) in the main belt than among NEAs. Here we evaluate these survey results, applying the same criteria for reliability of results that we apply to all results listed in our Lightcurve Database (Warner, B.D., Harris, A.W., Pravec, P. [2009a]. Icarus 202, 134-146). In doing so, we assigned reliability estimates judged sufficient for inclusion in statistical studies for only 27 out of 83 (33%) periods claimed by Dermawan, and only 87 out of 218 (40%) periods reported by Masiero et al.; none of the super-fast rotators larger than about 250 m diameter claimed by either survey received a reliability rating judged sufficient for analysis. We find no reliable basis for the claim of different rotation properties between main belt and near-Earth asteroids. Our analysis presents a cautionary message for future surveys.
Automatable algorithms to identify nonmedical opioid use using electronic data: a systematic review.

Improved methods to identify nonmedical opioid use can help direct health care resources to individuals who need them. Automated algorithms that use large databases of electronic health care claims or records for surveillance are a potential means to achieve this goal. In this systematic review, we reviewed the utility, attempts at validation, and application of such algorithms to detect nonmedical opioid use. We searched PubMed and Embase for articles describing automatable algorithms that used electronic health care claims or records to identify patients or prescribers with likely nonmedical opioid use. We assessed algorithm development, validation, and performance characteristics and the settings where they were applied. Study variability precluded a meta-analysis. Of 15 included algorithms, 10 targeted patients, 2 targeted providers, 2 targeted both, and 1 identified medications with high abuse potential. Most patient-focused algorithms (67%) used prescription drug claims and/or medical claims, with diagnosis codes of substance abuse and/or dependence as the reference standard. Eleven algorithms were developed via regression modeling. Four used natural language processing, data mining, audit analysis, or factor analysis. Automated algorithms can facilitate population-level surveillance. However, there is no true gold standard for determining nonmedical opioid use. Users must recognize the implications of identifying false positives and, conversely, false negatives. Few algorithms have been applied in real-world settings. Automated algorithms may facilitate identification of patients and/or providers most likely to need more intensive screening and/or intervention for nonmedical opioid use. Additional implementation research in real-world settings would clarify their utility. © The Author 2017.

Cochleovestibular symptoms, such as vertigo, tinnitus, and sudden deafness, are common manifestations of microvascular diseases. However, it is unclear whether these symptoms occurred preceding the diagnosis of peripheral artery occlusive disease (PAOD). Therefore, the aim of this case-control study was to investigate the risk of PAOD among patients with vertigo, tinnitus, and sudden deafness using a nationwide, population-based health claim database in Taiwan. We identified 5,340 adult patients with PAOD diagnosed between January 1, 2006 and December 31, 2010 and 16,020 controls, frequency matched on age interval, sex, and year of index date, from the Taiwan National Health Insurance Research Database. Risks of PAOD in patients with vertigo, tinnitus, or sudden deafness were separately evaluated with multivariate logistic regression analyses. Of the 5,340 patients with PAOD, 12.7%, 6.7%, and 0.3% were diagnosed with vertigo, tinnitus, and sudden deafness, respectively. In the controls, 10.6%, 6.1%, and 0.3% were diagnosed with vertigo (P < 0.001), tinnitus (P = 0.161), and sudden deafness (P = 0.774), respectively. Results from the multivariate logistic regression analyses showed that the risk of PAOD was significantly increased in patients with vertigo (adjusted odds ratio = 1.12, P = 0.027) but not in those with tinnitus or sudden deafness. A modest increase in the risk of PAOD was observed among Taiwanese patients with vertigo, after adjustment for comorbidities.

To estimate the employer costs associated with employee obesity. The study used cross-sectional analysis of employee health-risk assessment, disability, workers' compensation, and medical claims data from 2006 to 2008. The study took place in the United States from 2006 to 2008. A panel database with 29,699 employees drawn from a panel of employers and observed for 3 years each (N = 89,097) was used. Workdays lost owing to illness and disability; the cost of medical, short-term disability, and workers' compensation claims; and employees' adjusted body mass indices (BMI) were measured. We model the number and probability of workdays lost from illness, short-term disability, and workers' compensation events; short-term disability and workers' compensation payments; and health care spending as a function of BMI. We estimate spline regression models and fit results using a third-degree fractional polynomial. Probability of disability, workers' compensation claims, and number of days missed owing to any cause increase with BMI above 25, as do total employer costs. The probability of a short-term disability claim increases faster for employees with hypertension, hyperlipidemia, or diabetes. Normal weight employees cost on average $3830 per year in covered medical, sick day, short-term disability, and workers' compensation claims combined; morbidly obese employees cost more than twice that amount, or $8067, in 2011 dollars. Obesity is associated with large employer costs from direct health care and insurance claims and indirect costs from lost productivity owing to workdays lost because of illness and disability.

Lopéz-Galán, Belinda; De Magistris, Tiziana
2017-02-01
Introduction: Although previous studies have provided relevant information regarding the progress in the implementation of Regulation (EC) No 1924/2006 of the European Union. So far it not determined the prevalence of relevant nutrition claims in preventing obesity in the Spanish market. Objective: To determine the prevalence of relevant nutritional claims related to prevent the obesity in the Spanish market. Material and methods: A database with 9 food product categories and it nutritional claims was created. Three supermarket chains were included because they represent the 40% of market share. Only the nutritional claims that mention nutrients related obesity was considered. Results: A total of 4,568 products were examined and a total of 900 nutrition claims were found in 20% of the products found. The most frequent nutrients referred in the nutritional claims were fat (42%), sugar (32%), dietary fibre (20%) and salt (6%). Conclusions: In accordance with previous studies, findings reported a low prevalence of nutritional claims indicating that agrifood sector should include more nutritional claims to help consumers making better food choices.
Validity of juvenile idiopathic arthritis diagnoses using administrative health data.
Stringer, Elizabeth; Bernatsky, Sasha
2015-03-01
Administrative health databases are valuable sources of data for conducting research including disease surveillance, outcomes research, and processes of health care at the population level. There has been limited use of administrative data to conduct studies of pediatric rheumatic conditions and no studies validating case definitions in Canada. We report a validation study of incident cases of juvenile idiopathic arthritis in the Canadian province of Nova Scotia. Cases identified through administrative data algorithms were compared to diagnoses in a clinical database. The sensitivity of algorithms that included pediatric rheumatology specialist claims was 81-86%. However, 35-48% of cases that were identified could not be verified in the clinical database depending on the algorithm used. Our case definitions would likely lead to overestimates of disease burden. Our findings may be related to issues pertaining to the non-fee-for-service remuneration model in Nova Scotia, in particular, systematic issues related to the process of submitting claims.
Malpractice litigation and nursing home quality of care.

To assess the potential deterrent effect of nursing home litigation threat on nursing home quality. We use a panel dataset of litigation claims and Nursing Home Online Survey Certification and Reporting (OSCAR) data from 1995 to 2005 in six states: Florida, Illinois, Wisconsin, New Jersey, Missouri, and Delaware, for a total of 2,245 facilities. Claims data are from Westlaw's Adverse Filings database, a proprietary legal database, on all malpractice, negligence, and personal injury/wrongful death claims filed against nursing facilities. A lagged 2-year moving average of the county-level number of malpractice claims is used to represent the threat of litigation. We use facility fixed-effects models to examine the relationship between the threat of litigation and nursing home quality. We find significant increases in registered nurse-to-total staffing ratios in response to rising malpractice threat, and a reduction in pressure sores among highly staffed facilities. However, the magnitude of the deterrence effect is small. Deterrence in response to the threat of malpractice litigation is unlikely to lead to widespread improvements in nursing home quality. This should be weighed against other benefits and costs of litigation to assess the net benefit of tort reform. © Health Research and Educational Trust.

The Ebola outbreak of 2013–15 infected more than 28 000 people and claimed more lives than all previous filovirus outbreaks combined. Governmental agencies, clinical teams, and the world scientific community pulled together in a multifaceted response ranging from prevention and disease control, to evaluating vaccines and therapeutics in human trials. As this epidemic is finally coming to a close, refocusing on long-term prevention strategies becomes paramount. Given the very real threat of future filovirus outbreaks, and the inherent uncertainty of the next outbreak virus and geographic location, it is prudent to consider the extent and implications of known natural diversity in advancing vaccines and therapeutic approaches. To facilitate such consideration, we have updated and enhanced the content of the filovirus portion of Los Alamos Hemorrhagic Fever Viruses Database. We have integrated and performed baseline analysis of all family Filoviridae sequences deposited into GenBank, with associated immune response data, and metadata, and we have added new computational tools with web-interfaces to assist users with analysis. Here, we (i) describe the main features of updated database, (ii) provide integrated views and some basic analyses summarizing evolutionary patterns as they relate to geo-temporal data captured in the database and (iii) highlight the most conserved regions in the proteome that may be useful for a T cell vaccine strategy.

To determine productivity loss and indirect costs with deep vein thrombosis (DVT) and pulmonary embolism (PE). Medical and pharmacy claims with short-term disability (STD) and long-term disability (LTD) claims from 2007 to 2010 were analyzed from the Integrated Benefits Institute's Health and Productivity Benchmarking (IBI-HPB) database (STD and LTD claims) and IMS LifeLink™ data (medical and pharmacy claims), which were indirectly linked using a weighting approach matching from IBI-HPB patients' demographic distribution. A total of 5442 DVT and 6199 PE claims were identified. Employees with DVT lost 57 STD and 440 LTD days per disability incident. The average per claim productivity loss from STD and LTD was $7414 and $58181, respectively. Employees with PE lost 56 STD and 364 LTD days per disability incident. The average per claim productivity loss from STD and LTD was $7605 and $48,751, respectively. Deep vein thrombosis and PE impose substantial economic burdens.

Context Suicidal behavior has gained attention as an adverse outcome of prescription drug use. Hospitalizations for intentional self-harm, including suicide, can be identified in administrative claims databases using external cause of injury codes (E-codes). However, rates of E-code completeness in US government and commercial claims databases are low due to issues with hospital billing software. Objective To develop an algorithm to identify intentional self-harm hospitalizations using recorded injury and psychiatric diagnosis codes in the absence of E-code reporting. Methods We sampled hospitalizations with an injury diagnosis (ICD-9 800–995) from 2 databases with high rates of E-coding completeness: 1999–2001 British Columbia, Canada data and the 2004 U.S. Nationwide Inpatient Sample. Our gold standard for intentional self-harm was a diagnosis of E950-E958. We constructed algorithms to identify these hospitalizations using information on type of injury and presence of specific psychiatric diagnoses. Results The algorithm that identified intentional self-harm hospitalizations with high sensitivity and specificity was a diagnosis of poisoning; toxic effects; open wound to elbow, wrist, or forearm; or asphyxiation; plus a diagnosis of depression, mania, personality disorder, psychotic disorder, or adjustment reaction. This had a sensitivity of 63%, specificity of 99% and positive predictive value (PPV) of 86% in the Canadian database. Values in the US data were 74%, 98%, and 73%. PPV was highest (80%) in patients under 25 and lowest those over 65 (44%). Conclusions The proposed algorithm may be useful for researchers attempting to study intentional self-harm in claims databases with incomplete E-code reporting, especially among younger populations.

To investigate the factors associated with outcomes and medical costs for percutaneous nephrolithotomy (PCNL). The present study uses a subset of the National Health Insurance Research Database (NHIRD), known as the Longitudinal Health Insurance Database 2005 (LHID 2005), which contains the data of all medical benefit claims from 1997 to 2010 for a subset of 1 million enrollees randomly drawn from the population of 22.72 million persons who were enrolled in 2005. The claims data for all subjects with a diagnosis of urolithiasis who underwent PCNL were analyzed. Hospital and surgeon case volume were classified by quartile. The correlations of all patient, surgeon, and hospital variables with the outcomes and medical costs of PCNL were analyzed by generalized estimating equations. A total of 995 subjects received PCNL. In univariate analysis, PCNL performed by high-volume surgeons (≥12) cost 26% less ($2684 vs $1986) and resulted in a 34.3% shorter hospital stay (6.5 vs 9.9 days) compared with low-volume surgeons (≤3). In multivariate analysis, surgeon volume was a significant predictor for medical cost, length of stay, and intensive care unit transfer but not complications and mortality. Surgeon volume was associated with lower medical costs and shorter length of stay after PCNL. Surgeon volume, however, was not an independent predictor of complications and mortality. Our findings have important implications for urologists and policymakers with regard to the cost and effectiveness of PCNL.

Few studies explore the magnitude of the disease burden and health care utilization imposed by renal disease among patients with hepatitis C virus (HCV). We aimed to describe the characteristics, outcomes, and health care utilization and costs of patients with HCV with and without renal impairment. This retrospective analysis used 2 administrative claims databases: the US commercially insured population in Truven Health MarketScan® data (aged 20-64 years), and the US Medicare fee-for-service population in the Medicare 20% sample (aged ≥65 years). Baseline characteristics and comorbid conditions were identified from claims during 2011; patients were followed for up to 1 year (beginning January 1, 2012) to identify health outcomes of interest and health care utilization and costs. In the MarketScan and Medicare databases, 35,965 and 10,608 patients with HCV were identified, 8.5 and 26.5% with evidence of renal disease (chronic kidney disease [CKD] or end-stage renal disease [ESRD]). Most comorbid conditions and unadjusted outcome rates increased across groups from patients with no evidence of renal disease to non-ESRD CKD to ESRD. Health care utilization followed a similar pattern, as did the costs. Our findings suggest that HCV patients with concurrent renal disease have significantly more comorbidity, a higher likelihood of negative health outcomes, and higher health care utilization and costs. © 2017 S.

Recently, published studies have reported conflicting results regarding the association between efavirenz exposure and the risk of suicidality among patients with human immunodeficiency virus. The objective of this analysis was to compare the rate of suicidality among patients initiating efavirenz-containing versus efavirenz-free antiretroviral (ARV) regimens.This retrospective cohort study used US administrative claims data for commercially and Medicaid-insured individuals for the years 2006 to 2013. ARV-naive patients aged ≥12 years initiating an efavirenz-containing or efavirenz-free ARV regimen with ≥6 months of continuous insurance enrollment prior to ARV initiation were selected. The primary outcome was suicidality, defined as the occurrence of any medical claim with a diagnosis code for suicidal ideation or an inpatient or emergency department medical claim for suicide attempt. Unadjusted incidence rates were calculated and propensity score-adjusted hazard ratios were estimated to account for differences in patient characteristics.There were 19,983 patients (efavirenz-containing, n = 11,187; efavirenz-free, n = 8796) in the commercial database and 5154 patients (efavirenz-containing, n = 2224; efavirenz-free, n = 2930) in the Medicaid database. Unadjusted incidence rates (95% confidence interval [CI]) of suicidality per 1000 person-years were: commercial, efavirenz-containing (3.3 [2.4-4.4]), efavirenz-free (4.0 [2.7-5.8]); Medicaid, efavirenz-containing (25.7 [18.8-34.4]), efavirenz-free (40.6 [31.9-50.9]). In propensity score-adjusted analyses, efavirenz use was not associated with suicidality: adjusted hazard ratio (95% CI) of suicidality compared with efavirenz-free regimen, commercial, 1.029 (0.636-1.665); Medicaid, 0.902 (0.617-1.319).This analysis found no conclusive evidence of an increased risk of suicidality among patients initiating an efavirenz-containing ARV regimen. However, channeling bias may exist even after adjusting for measured patient characteristics.

Endometriosis is a painful, chronic disease affecting 5.5 million women and girls in the United States and Canada and millions more worldwide. The usual age range of women diagnosed with endometriosis is 20 to 45 years. Endometriosis has an estimated prevalence of 10% among women of reproductive age, although estimates of prevalence vary greatly. Endometriosis is the most common gynecological cause of chronic pelvic pain, but published information on its associated medical care costs is scarce. The aim of this study was to determine (1) the prevalence of endometriosis in the United States, (2) the amount of health care services used by women coded with endometriosis in a commercial medical claims database during 1999 to 2003, and (3) the endometriosis-related costs for 2003, the most recent data available at the time the study was performed. This study was a retrospective review of administrative data for commercial payers, which included enrollment, eligibility, and claims payment data contained in the Medstat Marketscan database for approximately 4 million commercial insurance members. All claims and membership data were extracted for each woman aged 18 to 55 years who had at least 1 medical or hospital claim with a diagnosis code for endometriosis (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes 617.00-617.99) for 1999 through 2003. Claims data from 1999 through 2003 were used to determine prevalence and health care resource utilization (i.e., annual admission rate, annual surgical rate, distribution of endometriosis-related surgeries, and prevalence of comorbid conditions). The cost analysis was based on claims from 2003 only. Cost was defined as the payer-allowed charge, which equals the net payer cost plus member cost share. The prevalence of women with medical claims (inpatient and/or outpatient) containing ICD-9-CM codes for endometriosis was 1.1% for the age band of 30 to 39 years and 0.7% over the entire age span of 18 to 55 years. The medical costs per patient per month (PPPM) for women with endometriosis were 63% greater ($706 PPPM) than those of the average woman per member per month ($433) in 2003; inpatient hospital costs accounted for 32% of total direct medical costs. Between 1999 and 2003, these women with endometriosis who were identified by either inpatient and/or outpatient claims had high rates of hospital admission (53% for any reason; 38% for an endometriosis-related reason) and a high annual surgical procedure rate (64%). Additionally, women with endometriosis frequently suffered from comorbid conditions, and these conditions were associated with greater PPPM costs of 15% to 50% for women with an endometriosis diagnosis code, depending on the condition. Interstitial cystitis was associated with 50% greater cost ($1,061 PPPM); depression, 41% ($997 PPPM); migraine, 40% ($988 PPPM); irritable bowel syndrome, 34% ($943 PPPM); chronic fatigue syndrome, 29% ($913 PPPM); abdominal pain, 20% ($846 PPPM); and infertility, 15% ($813 PPPM). Women with endometriosis have a high hospital admission rate and surgical procedure rate and a high incidence of comorbid conditions. Consequently, these women incur total medical costs that are, on average, 63% higher than medical costs for the average woman in a commercially insured group.
[Surgical assessment of complications after thyroid gland operations].
Dralle, H
2015-01-01
The extent, magnitude and technical equipment used for thyroid surgery has changed considerably in Germany during the last decade. The number of thyroidectomies due to benign goiter have decreased while the extent of thyroidectomy, nowadays preferentially total thyroidectomy, has increased. Due to an increased awareness of surgical complications the number of malpractice claims is increasing. In contrast to surgical databases the frequency of complications in malpractice claims reflects the individual impact of complications on the quality of life. In contrast to surgical databases unilateral and bilateral vocal fold palsy are therefore at the forefront of malpractice claims. As guidelines are often not applicable for the individual surgical expert review, the question arises which are the relevant criteria for the professional expert witness assessing the severity of the individual complication. While in surgical databases major complications after thyroidectomy, such as vocal fold palsy, hypoparathyroidism, hemorrhage and infections are equally frequent (1-3 %), in malpractice claims vocal fold palsy is significantly more frequent (50 %) compared to hypoparathyroidism (15 %), hemorrhage and infections (about 5 % each). To avoid bilateral nerve palsy intraoperative nerve monitoring has become of utmost importance for surgical strategy and malpractice suits alike. For surgical expert review documentation of individual risk-oriented indications, the surgical approach and postoperative management are highly important. Guidelines only define the treatment corridors of good clinical practice. Surgical expert reviews in malpractice suits concerning quality of care and causality between surgical management, complications and sequelae of complications are therefore highly dependent on the grounds and documentation of risk-oriented indications for thyroidectomy, intraoperative and postoperative surgical management.

Long-term outcomes after stepping down asthma medications are not well described. This study was a retrospective time-to-event analysis of individuals diagnosed with asthma who stepped down their asthma controller medications using a US claims database spanning 2000 to 2012. Four-month intervals were established and a step-down event was defined by a ≥ 50% decrease in days-supplied of controller medications from one interval to the next; this definition is inclusive of step-down that occurred without health-care provider guidance or as a consequence of a medication adherence lapse. Asthma stability in the period prior to step-down was defined by not having an asthma exacerbation (inpatient visit, ED visit, or dispensing of a systemic corticosteroid linked to an asthma visit) and having fewer than two rescue inhaler claims in a 4-month period. The primary outcome in the period following step-down was time-to-first asthma exacerbation. Thirty-two percent of the 26,292 included individuals had an asthma exacerbation in the 24-month period following step-down of asthma controller medication, though only 7% had an ED visit or hospitalization for asthma. The length of asthma stability prior to stepping down asthma medication was strongly associated with the risk of an asthma exacerbation in the subsequent 24-month period: < 4 months' stability, 44%; 4 to 7 months, 34%; 8 to 11 months, 30%; and ≥ 12 months, 21% (P < .001). In a large, claims-based, real-world study setting, 32% of individuals have an asthma exacerbation in the 2 years following a step-down event.

Online mapping, miniaturization of computing devices, the "cloud", Global Navigation Satellite System (GNSS) and cell tower triangulation all coalesce into an entirely novel infrastructure for numerous innovative map applications. This impacts the planning of human activities, navigating and tracking these activities as they occur, and finally documenting their outcome for either a single user or a network of connected users in a larger context. In this paper, we provide an example of a simple geospatial application making use of this model, which we will use to explain the basic steps necessary to deploy an application involving a web service hosting geospatial information and a client software consuming the web service through an API. The application allows an insurance claim specialist to add claims to a cloud-based database including a claim location. A field agent then uses a smartphone application to query the database by proximity, and heads out to capture photographs as supporting documentation for the claim. Once the photos have been uploaded to the web service, a second web service for image matching is called in order to try and match the current photograph to previously submitted assets. Image matching is used as a pre-verification step to determine whether the coverage of the respective object is sufficient for the claim specialist to process the claim. The development of the application was based on Microsoft's® Bing Maps™, Windows Phone™, Silverlight™, Windows Azure™ and Visual Studio™, and was completed in approximately 30 labour hours split among two developers.

End-stage renal disease (ESRD) is a major public health problem with increasing prevalence and costs. An understanding of the long-term trends in dialysis rates and outcomes can help inform health policy. We determined the optimal case definition for the diagnosis of ESRD using administrative claims data in the province of Manitoba over a 7-year period. We determined the sensitivity, specificity, predictive value and overall accuracy of 4 administrative case definitions for the diagnosis of ESRD requiring chronic dialysis over different time horizons from Jan. 1, 2004, to Mar. 31, 2011. The Manitoba Renal Program Database served as the gold standard for confirming dialysis status. During the study period, 2562 patients were registered as recipients of chronic dialysis in the Manitoba Renal Program Database. Over a 1-year period (2010), the optimal case definition was any 2 claims for outpatient dialysis, and it was 74.6% sensitive (95% confidence interval [CI] 72.3%-76.9%) and 94.4% specific (95% CI 93.6%-95.2%) for the diagnosis of ESRD. In contrast, a case definition of at least 2 claims for dialysis treatment more than 90 days apart was 64.8% sensitive (95% CI 62.2%-67.3%) and 97.1% specific (95% CI 96.5%-97.7%). Extending the period to 5 years greatly improved sensitivity for all case definitions, with minimal change to specificity; for example, for the optimal case definition of any 2 claims for dialysis treatment, sensitivity increased to 86.0% (95% CI 84.7%-87.4%) at 5 years. Accurate case definitions for the diagnosis of ESRD requiring dialysis can be derived from administrative claims data. The optimal definition required any 2 claims for outpatient dialysis. Extending the claims period to 5 years greatly improved sensitivity with minimal effects on specificity for all case definitions.

Administrative health care databases offer an efficient and accessible, though as-yet unvalidated, approach to studying outcomes of patients with chronic kidney disease and end-stage renal disease (ESRD). The objective of this study is to determine the validity of outpatient physician billing derived algorithms for defining chronic dialysis compared to a reference standard ESRD registry. A cohort of incident dialysis patients (Jan. 1-Dec. 31, 2008) and prevalent chronic dialysis patients (Jan 1, 2008) was selected from a geographically inclusive ESRD registry and administrative database. Four administrative data definitions were considered: at least 1 outpatient claim, at least 2 outpatient claims, at least 2 outpatient claims at least 90 days apart, and continuous outpatient claims at least 90 days apart with no gap in claims greater than 21 days. Measures of agreement of the four administrative data definitions were compared to a reference standard (ESRD registry). Basic patient characteristics are compared between all 5 patient groups. 1,118,097 individuals formed the overall population and 2,227 chronic dialysis patients were included in the ESRD registry. The three definitions requiring at least 2 outpatient claims resulted in kappa statistics between 0.60-0.80 indicating "substantial" agreement. "At least 1 outpatient claim" resulted in "excellent" agreement with a kappa statistic of 0.81. Of the four definitions, the simplest (at least 1 outpatient claim) performed comparatively to other definitions. The limitations of this work are the billing codes used are developed in Canada, however, other countries use similar billing practices and thus the codes could easily be mapped to other systems. Our reference standard ESRD registry may not capture all dialysis patients resulting in some misclassification. The registry is linked to on-going care so this is likely to be minimal. The definition utilized will vary with the research objective.

Osteoporosis, osteoporosis-related fractures, and diabetes are considerable health burdens in Japan. Diabetes in patients with osteoporosis has been reported to be associated with increased fracture risk. This retrospective analysis of a Japanese hospital claims database investigated the real-world effect of type 2 diabetes mellitus (T2DM) on the incidence of clinical fractures, costs, and healthcare resource utilization in patients with osteoporosis and a subgroup of patients prescribed raloxifene. Women aged ≥50 years diagnosed with osteoporosis who had a first prescription claim for osteoporosis treatment with a pre-index period ≥12 months and a post-index period of 30 months were selected from a database extract (April 2008-July 2013). Patients prescribed raloxifene were classed as a subgroup. Patients diagnosed with T2DM constituted the T2DM group; all other patients (excluding patients with type 1 diabetes mellitus) constituted the non-diabetes mellitus (non-DM) group. Groups were matched by exact matching, using selected baseline characteristics. Patient demographic and clinical characteristics were compared using chi-squared tests, t-tests, or Wilcoxon rank sum tests. Time to first fracture was examined using Kaplan-Meier survival analysis. Overall, the T2DM and non-DM groups had 7580 and 7979 patients, respectively; following matching, there were 3273 patients per group. In the raloxifene subgroup, the T2DM and non-DM groups had 668 and 699 patients, respectively; following matching, there were 239 patients per group. At baseline, the T2DM group (overall and raloxifene subgroup) had significantly higher healthcare resource utilization and comorbidities. During the post-index period, a similar pattern was observed in the overall group, even after matching; the T2DM group also had a higher incidence of fracture. In the raloxifene subgroup, after matching, there were no significant differences in fracture incidence or costs and fewer differences in healthcare resource utilization between the T2DM and non-DM groups. These findings suggest that comorbid T2DM increases fracture incidence in patients with osteoporosis, compared with patients without DM. Increases in fracture incidence were accompanied by greater costs and healthcare resource utilization, which are important considerations for clinical practice in Japan. Further research investigating the use of raloxifene for treatment of osteoporosis with comorbid T2DM may also be warranted.

Following a lengthy strike, several hundred delivery drivers filed workers compensation claims for occupational hearing loss. We were asked to evaluate the noise exposure of the drivers during their in-plant tasks. In-plant exposures were not predictive of any hearing loss. A comparison of audiometric data for the claimants revealed consistent hearing loss independent of duration of employment or age. These discrepancies between observations and common understanding of dose-response relationships between noise exposure and hearing loss led to further investigation, ultimately resulting in the dismissal of all claims against the employer who then filed an action against the claimant's attorneys and physician under the Racketeering in Corrupt Organizations Act (RICO). The details of the legal complaint, which reads like a detective novel, can be found at the United States District Court for the Southern District of New York [93 Civ. 7222 (LAP)].

This was a retrospective analysis of 3951 workers' compensation claimants between 1981 and 2009 representing municipal workplaces. A BMI scale composed of seven levels, including two overweight tiers, was used. Higher BMI levels were related to more lost workdays, indemnity costs, and total costs. Medical care costs were virtually the same in overweight and obese claimants and moderately higher than claimants with recommended BMIs. Males were more likely to incur workers' compensation claims than females across all BMI tiers; yet, obese females incurred twice as many lost workdays and indemnity costs, and nearly 50% higher medical costs and total costs than obese men. Elevated levels of BMI negatively influence several workers' compensation outcome measures.

After the launch of dipeptidyl peptidase-4 (DPP-4), a new oral hypoglycemic drug (OHD), in December 2009, severe hypoglycemia cases were reported in Japan. Although the definite cause was unknown, co-administration with sulfonylureas (SU) was suspected as one of the potential risk factors. The Japan Association for Diabetes Education and Care (JADEC) released a recommendation in April 2010 to lower the dose of three major SUs (glimepiride, glibenclamide, and gliclazide) when adding a DPP-4 inhibitor. To evaluate the effectiveness of this risk minimization action along with labeling changes, dispensing records for 114,263 patients prescribed OHDs between December 2008 and December 2010 were identified in the Nihon-Chouzai pharmacy claims database. The adherence to the recommended dosing of SU co-prescribed with DPP-4 inhibitors increased from 46.3% before to 63.8% after the JADEC recommendation (p < 0.01 by time-series analysis), while no change was found in those for SU monotherapy and SU with other OHD co-prescriptions. The adherence was significantly worse for those receiving a glibenclamide prescription. The JADEC recommendation, along with labeling changes, appeared to have a favorable effect on the risk minimization action in Japan. In these instances, a pharmacy claims database can be a useful tool to evaluate risk minimization actions. PMID:24300302

Use of large databases for orthopedic research has become extremely popular in recent years. Each database varies in the methods used to capture data and the population it represents. The purpose of this study was to evaluate how these databases differed in reported demographics, comorbidities, and postoperative complications for primary total hip arthroplasty (THA) patients. Primary THA patients were identified within National Surgical Quality Improvement Programs (NSQIP), Nationwide Inpatient Sample (NIS), Medicare Standard Analytic Files (MED), and Humana administrative claims database (HAC). NSQIP definitions for comorbidities and complications were matched to corresponding International Classification of Diseases, 9th Revision/Current Procedural Terminology codes to query the other databases. Demographics, comorbidities, and postoperative complications were compared. The number of patients from each database was 22,644 in HAC, 371,715 in MED, 188,779 in NIS, and 27,818 in NSQIP. Age and gender distribution were clinically similar. Overall, there was variation in prevalence of comorbidities and rates of postoperative complications between databases. As an example, NSQIP had more than twice the obesity than NIS. HAC and MED had more than 2 times the diabetics than NSQIP. Rates of deep infection and stroke 30 days after THA had more than 2-fold difference between all databases. Among databases commonly used in orthopedic research, there is considerable variation in complication rates following THA depending upon the database used for analysis. It is important to consider these differences when critically evaluating database research. Additionally, with the advent of bundled payments, these differences must be considered in risk adjustment models. Copyright © 2017 Elsevier Inc. All rights reserved.

Starting from the famous phrase “extraordinary claims require extraordinary evidence,” we will present the evidence supporting the concept that human visual perception may have non-local properties, in other words, that it may operate beyond the space and time constraints of sensory organs, in order to discuss which criteria can be used to define evidence as extraordinary. This evidence has been obtained from seven databases which are related to six different protocols used to test the reality and the functioning of non-local perception, analyzed using both a frequentist and a new Bayesian meta-analysis statistical procedure. According to a frequentist meta-analysis, the null hypothesis can be rejected for all six protocols even if the effect sizes range from 0.007 to 0.28. According to Bayesian meta-analysis, the Bayes factors provides strong evidence to support the alternative hypothesis (H1) over the null hypothesis (H0), but only for three out of the six protocols. We will discuss whether quantitative psychology can contribute to defining the criteria for the acceptance of new scientific ideas in order to avoid the inconclusive controversies between supporters and opponents.

Background Cochleovestibular symptoms, such as vertigo, tinnitus, and sudden deafness, are common manifestations of microvascular diseases. However, it is unclear whether these symptoms occurred preceding the diagnosis of peripheral artery occlusive disease (PAOD). Therefore, the aim of this case-control study was to investigate the risk of PAOD among patients with vertigo, tinnitus, and sudden deafness using a nationwide, population-based health claim database in Taiwan. Methods We identified 5,340 adult patients with PAOD diagnosed between January 1, 2006 and December 31, 2010 and 16,020 controls, frequency matched on age interval, sex, and year of index date, from the Taiwan National Health Insurance Research Database. Risks of PAOD in patients with vertigo, tinnitus, or sudden deafness were separately evaluated with multivariate logistic regression analyses. Results Of the 5,340 patients with PAOD, 12.7%, 6.7%, and 0.3% were diagnosed with vertigo, tinnitus, and sudden deafness, respectively. In the controls, 10.6%, 6.1%, and 0.3% were diagnosed with vertigo (P < 0.001), tinnitus (P = 0.161), and sudden deafness (P = 0.774), respectively. Results from the multivariate logistic regression analyses showed that the risk of PAOD was significantly increased in patients with vertigo (adjusted odds ratio = 1.12, P = 0.027) but not in those with tinnitus or sudden deafness. Conclusions A modest increase in the risk of PAOD was observed among Taiwanese patients with vertigo, after adjustment for comorbidities. PMID:27631630

We describe and compare the availability and accessibility of administrative healthcare databases (AHDB) in several Asia-Pacific countries: Australia, Japan, South Korea, Taiwan, Singapore, China, Thailand, and Malaysia. The study included hospital records, reimbursement databases, prescription databases, and data linkages. Databases were first identified through PubMed, Google Scholar, and the ISPOR database register. Database custodians were contacted. Six criteria were used to assess the databases and provided the basis for a tool to categorise databases into seven levels ranging from least accessible (Level 1) to most accessible (Level 7). We also categorised overall data accessibility for each country as high, medium, or low based on accessibility of databases as well as the number of academic articles published using the databases. Fifty-four administrative databases were identified. Only a limited number of databases allowed access to raw data and were at Level 7 [Medical Data Vision EBM Provider, Japan Medical Data Centre (JMDC) Claims database and Nihon-Chouzai Pharmacy Claims database in Japan, and Medicare, Pharmaceutical Benefits Scheme (PBS), Centre for Health Record Linkage (CHeReL), HealthLinQ, Victorian Data Linkages (VDL), SA-NT DataLink in Australia]. At Levels 3-6 were several databases from Japan [Hamamatsu Medical University Database, Medi-Trend, Nihon University School of Medicine Clinical Data Warehouse (NUSM)], Australia [Western Australia Data Linkage (WADL)], Taiwan [National Health Insurance Research Database (NHIRD)], South Korea [Health Insurance Review and Assessment Service (HIRA)], and Malaysia [United Nations University (UNU)-Casemix]. Countries were categorised as having a high level of data accessibility (Australia, Taiwan, and Japan), medium level of accessibility (South Korea), or a low level of accessibility (Thailand, China, Malaysia, and Singapore). In some countries, data may be available but accessibility was restricted based on requirements by data custodians. Compared with previous research, this study describes the landscape of databases in the selected countries with more granularity using an assessment tool developed for this purpose. A high number of databases were identified but most had restricted access, preventing their potential use to support research. We hope that this study helps to improve the understanding of the AHDB landscape, increase data sharing and database research in Asia-Pacific countries.

Use of large clinical and administrative databases for orthopaedic research has increased exponentially. Each database represents unique patient populations and varies in their methodology of data acquisition, which makes it possible that similar research questions posed to different databases might result in answers that differ in important ways. (1) What are the differences in reported demographics, comorbidities, and complications for patients undergoing primary TKA among four databases commonly used in orthopaedic research? (2) How does the difference in reported complication rates vary depending on whether only inpatient data or 30-day postoperative data are analyzed? Patients who underwent primary TKA during 2010 to 2012 were identified within the National Surgical Quality Improvement Programs (NSQIP), the Nationwide Inpatient Sample (NIS), the Medicare Standard Analytic Files (MED), and the Humana Administrative Claims database (HAC). NSQIP is a clinical registry that captures both inpatient and outpatient events up to 30 days after surgery using clinical reviewers and strict definitions for each variable. The other databases are administrative claims databases with their comorbidity and adverse event data defined by diagnosis and procedure codes used for reimbursement. NIS is limited to inpatient data only, whereas HAC and MED also have outpatient data. The number of patients undergoing primary TKA from each database was 48,248 in HAC, 783,546 in MED, 393,050 in NIS, and 43,220 in NSQIP. NSQIP definitions for comorbidities and surgical complications were matched to corresponding International Classification of Diseases, 9 Revision/Current Procedural Terminology codes and these coding algorithms were used to query NIS, MED, and HAC. Age, sex, comorbidities, and inpatient versus 30-day postoperative complications were compared across the four databases. Given the large sample sizes, statistical significance was often detected for small, clinically unimportant differences; thus, the focus of comparisons was whether the difference reached an absolute difference of twofold to signify an important clinical difference. Although there was a higher proportion of males in NIS and NSQIP and patients in NIS were younger, the difference was slight and well below our predefined threshold for a clinically important difference. There was variation in the prevalence of comorbidities and rates of postoperative complications among databases. The prevalence of chronic obstructive pulmonary disease (COPD) and coagulopathy in HAC and MED was more than twice that in NIS and NSQIP (relative risk [RR] for COPD: MED versus NIS 3.1, MED versus NSQIP 4.5, HAC versus NIS 3.6, HAC versus NSQIP 5.3; RR for coagulopathy: MED versus NIS 3.9, MED versus NSQIP 3.1, HAC versus NIS 3.3, HAC versus NSQIP 2.7; p < 0.001 for all comparisons). NSQIP had more than twice the obesity as NIS (RR 0.35). Rates of stroke within 30 days of TKA had more than a twofold difference among all databases (p < 0.001). HAC had more than twice the rates of 30-day complications at all endpoints compared with NSQIP and more than twice the 30-day infections as MED. A comparison of inpatient and 30-day complications rates demonstrated more than twice the amount of wound infections and deep vein thromboses is captured when data are analyzed out to 30 days after TKA (p < 0.001 for all comparisons). When evaluating research utilizing large databases, one must pay particular attention to the type of database used (administrative claims, clinical registry, or other kinds of databases), time period included, definitions utilized for specific variables, and the population captured to ensure it is best suited for the specific research question. Furthermore, with the advent of bundled payments, policymakers must meticulously consider the data sources used to ensure the data analytics match historical sources. Level III, therapeutic study.

Hemophilia B requires replacement therapy with factor IX (FIX) coagulation products to treat and prevent bleeding episodes. A recently introduced extended half-life (EHL) recombinant FIX replacement product provided the opportunity to compare the amount of dispensed factor and expenditures for EHL treatment compared with a standard half-life (SHL) product. To determine factor international units (IUs) dispensed and expenditures associated with switching from nonacog alfa, the most commonly used SHL replacement product, to eftrenonacog alfa, an EHL FIX replacement product. Two U.S. claims databases were analyzed. A large national specialty pharmacy dispensation claims database was used to identify the number of IUs dispensed and monthly charges for all patients with hemophilia B from April 2015 to June 2016. Truven Health MarketScan Research Databases (January 2010-July 2016) were used to identify IUs and expenditures for patients with claims data for at least 3 months before and after switching from the SHL to the EHL product. Medians for IUs and expenditures are presented to accommodate for skewness of data distribution. The national specialty pharmacy database analysis included 296 patients with moderate or severe hemophilia B (233 on SHL; 94 on EHL). Median monthly factor dispensed was 11% lower (2,142 IU) in the EHL versus SHL cohort over the study period, while individual monthly reductions ranged from 32% to 47% (9,838 IU to 16,514 IU). Using the wholesale acquisition cost, the median per-patient monthly factor expenditures over the 15-month study period were 94% higher ($23,005) for the EHL than for the SHL product. Individual median monthly expenditure differences ranged from 15% ($6,562) to 49% ($19,624). In the Truven database, 14 patients switched from the SHL to the EHL product. The amount of factor dispensed was variable; in the 1-year period before and after the switch from the SHL to the EHL product, mean IUs dispensed decreased by 3,005 IU, while median IUs dispensed increased by 4,775 IU. Factor replacement expenditures were higher after switching from the SHL to the EHL product in each of the 3-month periods examined before versus after the switch. This analysis of real-world data showed that switching from the SHL to the EHL product was associated with higher expenditures. Increased expenditures noted in the first 3 months after switching may be related to initial stocking up of the EHL product, but expenditures were sustained throughout the 1-year period of data analysis. Further analysis of these findings with larger numbers of patients should be explored. This study was sponsored by Pfizer.

Objective. To assess the potential deterrent effect of nursing home litigation threat on nursing home quality. Data Sources/Study Setting. We use a panel dataset of litigation claims and Nursing Home Online Survey Certification and Reporting (OSCAR) data from 1995 to 2005 in six states: Florida, Illinois, Wisconsin, New Jersey, Missouri, and Delaware, for a total of 2,245 facilities. Claims data are from Westlaw's Adverse Filings database, a proprietary legal database, on all malpractice, negligence, and personal injury/wrongful death claims filed against nursing facilities. Study Design. A lagged 2-year moving average of the county-level number of malpractice claims is used to represent the threat of litigation. We use facility fixed-effects models to examine the relationship between the threat of litigation and nursing home quality. Principal Findings. We find significant increases in registered nurse-to-total staffing ratios in response to rising malpractice threat, and a reduction in pressure sores among highly staffed facilities. However, the magnitude of the deterrence effect is small. Conclusions. Deterrence in response to the threat of malpractice litigation is unlikely to lead to widespread improvements in nursing home quality. This should be weighed against other benefits and costs of litigation to assess the net benefit of tort reform. PMID:23741985

Delayed coverage of pathogens including meticillin-resistant Staphylococcus aureus (MRSA) in pneumonia and bacteraemia has been associated with increased mortality and length of hospital stay (LOS). However, less is known about the impact of delayed appropriate coverage in complicated skin and skin-structure infections (cSSSIs). To evaluate the clinical and economic outcomes associated with early versus late use of vancomycin in the management of patients hospitalized for cSSSIs. Retrospective analysis was performed using an inpatient claims database of >500 US hospitals in 2005. Using prescription claims, patients with primary or secondary cSSSI admissions were classified into three groups: 1 = early vancomycin monotherapy; 2 = early vancomycin combination therapy; 3 = late vancomycin therapy. Outcomes studied included LOS and inpatient hospital costs. One-way analysis of variance was used for unadjusted analysis and multivariate regression methods were used to control for co-variates. A total of 34,942 patients (27.78% of all patients with cSSSIs) were treated with vancomycin. Mean age was 54.7 years and 54.3% of the patients were males. Mean unadjusted total LOS was 8.46, 9.44 and 13.2 days, and hospital costs in 2005 values were USD10 211.94, USD12 361.94 and USD18 344.00 for groups 1, 2 and 3, respectively. In-hospital mortality rate was highest in group 3 (4.18%) and lowest in group 1 (1.75%). Generalized linear models used to control for potential confounding variables between early versus late vancomycin use suggest that among cSSSI patients late vancomycin use is an independent predictor of higher LOS and costs. In this large inpatient database, later vancomycin use in patients with cSSSIs appears to be significantly associated with higher LOS and total costs.

Our objective was to evaluate the utility of the national database (NDB) based on health insurance claims data for antimicrobial use (AMU) surveillance in medical institutions in Japan. The population-weighted total AMU expressed as defined daily doses (DDDs) per 1000 inhabitants per day (DID) was measured by the NDB. The data were compared with our previous study measured by the sales data. Trend analysis of DID from 2011 to 2013 and subgroup analysis stratified by antimicrobial category and age group were performed. There was a significant linear correlation between the AMUs measured by the sales data and the NDB. Total oral and parenteral AMUs (expressed in DID) were 1.04-fold from 12.654 in 2011 to 13.202 in 2013 and 1.13-fold from 0.734 to 0.829, respectively. Percentage of oral form among total AMU was high with more than 94% during the study period. AMU in the children group (0-14 years) decreased from 2011 to 2013 regardless of dosage form, although the working age group (15-64 years) and elderly group (65 and above years) increased. Oral AMU in the working age group was approximately two-thirds of those in the other age groups. In contrast, parenteral AMU in the elderly group was extremely high compared to the other age groups. The trend of AMU stratified by antimicrobial category and age group were successfully measured using the NDB, which can be a tool to monitor outcome indices for the national action plan on antimicrobial resistance.

We evaluated the effectiveness of a policy allowing for the sale of over-the-counter drugs outside of pharmacies by examining its effect on number of monthly outpatient visits for acute upper respiratory infections, dyspepsia, and migraine. We used medical claims data extracted from the Korean National Health Insurance Cohort Database from 2009 to 2013. The Korean National Health Insurance Cohort Database comprises a nationally representative sample of claims - about 2% of the entire population - obtained from the medical record data held by the Korean National Health Insurance Corporation (which has data on the entire nation). The analysis included26,284,706 person-months of 1,042,728 individuals. An interrupted-time series analysis was performed. Outcome measures were monthly outpatient visits for acute upper respiratory infections, dyspepsia, and migraine. To investigate the effect of the policy, we compared the number of monthly visits before and after the policy's implementation in 2012. For acute upper respiratory infections, monthly outpatient visits showed a decreasing trend before the policy (ß = -0.0003);after it, a prompt change and increasing trend in monthly outpatient visits were observed, but these were non-significant. For dyspepsia, the trend was increasing before implementation (ß = -0.0101), but this reversed after implementation(ß = -0.007). For migraine, an increasing trend was observed before the policy (ß = 0.0057). After it, we observed a significant prompt change (ß = -0.0314) but no significant trend. Deregulation of selling over-the-counter medication outside of pharmacies reduced monthly outpatient visits for dyspepsia and migraine symptoms, but not acute upper respiratory infections.

Current chronic obstructive pulmonary disease (COPD) exacerbation risk prediction models are based on clinical data not easily accessible to national quality-of-care organizations and payers. Models developed from data sources available to these organizations are needed. This study aimed to validate a risk measure constructed using pharmacy claims in patients with COPD. Administrative claims data were used to construct a risk model to test and validate the ratio of controller (maintenance) medications to total COPD medications (CTR) as an independent risk measure for COPD exacerbations. The ability of the CTR to predict the risk of COPD exacerbations was also assessed. This was a retrospective study using health insurance claims data from the Truven MarketScan database (2006-2011), whereby exacerbation risk factors of patients with COPD were observed over a 12-month period and exacerbations monitored in the following year. Exacerbations were defined as moderate (emergency department or outpatient treatment with oral corticosteroid dispensings within 7 d) or severe (hospital admission) on the basis of diagnosis codes. Models were developed and validated using split-sample data from the MarketScan database and further validated using the Reliant Medical Group database. The performance of prediction models was evaluated using C-statistics. A total of 258,668 patients with COPD from the MarketScan database were included. A CTR of greater than or equal to 0.3 was significantly associated with a reduced risk for any (adjusted odds ratio [OR], 0.91; 95% confidence interval [CI], 0.85-0.97); moderate (OR, 0.93; 95% CI, 0.87-1.00), or severe (OR, 0.87; 95% CI, 0.80-0.95) exacerbation. The CTR, at a ratio of greater than or equal to 0.3, was predictive in various subpopulations, including those without a history of asthma and those with or without a history of moderate/severe exacerbations. The C-statistics ranged from 0.750 to 0.761 for the development set and 0.714 to 0.761 in the validation sets, indicating the CTR performed well in predicting exacerbation risk. The ratio of controller to total medications dispensed for COPD is a measure that can easily be calculated using only pharmacy claims data. A CTR of greater than or equal to 0.3 can potentially be used as a quality-of-care measurement for prevention of exacerbations.

To identify the demographic and clinical characteristics of commercially insured and Medicaid patients with a diagnosis of opioid dependence or abuse and to describe the pharmacological and nonpharmacological treatments received by these patients. This was a retrospective observational study using de-identified administrative claims data. The analysis included commercially insured and Medicaid patient data extracted from the Truven Health MarketScan® Commercial and Medicaid Databases. Patients with a diagnosis of opioid dependence or abuse from 2008 to 2014 (earliest diagnosis = index date) and a minimum of 6 months of pre-index and postindex continuous enrollment in the database. Baseline demographic and clinical characteristics, medication-assisted treatment (MAT), and treatment other than MAT received following diagnosis, and the clinical practice setting in which patients received any opioid dependence-related care were reported. Data from commercially insured (N = 103,768) and Medicaid (N = 50,552) patients were analyzed. Common comorbid conditions included chronic pain (48.6 percent Commercial, 56.8 percent Medicaid), depressive disorder (24.0 percent Commercial, 32.8 percent Medicaid), and other substance abuse disorders (13.3 percent Commercial, 23.7 percent Medicaid). Nearly one third of both Commercial (31.6 percent) and Medicaid (33.6 percent) patients did not have any claims for psychosocial therapy or MAT during the follow-up period. Only 24.3 percent of Commercial patients and 20.4 percent of Medicaid patients had evidence of claims for both MAT and psychosocial treatment anytime following diagnosis. The results suggest that there are opportunities to improve care through comprehensive and coordinated treatment for opioid dependence/abuse. Policies aimed at improving treatment access may be warranted.

Context: Gaelic games (Gaelic football and hurling) are indigenous Irish sports with increasing global participation in recent years. Limited information is available on longitudinal injury trends. Reviews of insurance claims can reveal the economic burden of injury and guide cost-effective injury-prevention programs. Objective: To review Gaelic games injury claims from 2007–2014 for male players to identify the costs and frequencies of claims. Particular attention was devoted to lower limb injuries due to findings from previous epidemiologic investigations of Gaelic games. Design: Descriptive epidemiology study. Setting: Open-access Gaelic Athletic Association Annual Reports from 2007–2014 were reviewed to obtain annual injury-claim data. Patients or Other Participants: Gaelic Athletic Association players. Main Outcome Measure(s): Player age (youth or adult) and relationships between lower limb injury-claim rates and claim values, Gaelic football claims, hurling claims, youth claims, and adult claims. Results: Between 2007 and 2014, €64 733 597.00 was allocated to 58 038 claims. Registered teams had annual claim frequencies of 0.36 with average claim values of €1158.4 ± 192.81. Between 2007 and 2014, average adult claims were always greater than youth claims (6217.88 versus 1036.88), while Gaelic football claims were always greater than hurling claims (5395.38 versus 1859.38). Lower limb injuries represented 60% of all claims. The number of lower limb injury claims was significantly correlated with annual injury-claim expenses (r = 0.85, P = .01) and adult claims (r = 0.96, P = .01) but not with youth claims (r = 0.69, P = .06). Conclusions: Reducing lower limb injuries will likely reduce injury-claim expenses. Effective injury interventions have been validated in soccer, but whether such changes can be replicated in Gaelic games remains to be investigated. Injury-claim data should be integrated into current elite injury-surveillance databases to monitor the cost effectiveness of current programs. PMID:26967548

Nutrition and health claims are displayed to influence consumers' food choices. This study assessed the extent and nature of nutrition and health claims on the front-of-pack of 'healthy' and 'less-healthy' packaged foods in New Zealand. Foods from eight categories, for which consumption may affect the risk of obesity and diet-related chronic diseases, were selected from the 2014 Nutritrack database. The internationally standardised International Network for Food and Obesity/Non-Communicable Diseases Research, Monitoring and Action Support (INFORMAS) taxonomy was used to classify claims on packages. The Nutrient Profiling Scoring Criterion (NPSC) was used to classify products as 'healthy' or 'less healthy'. In total, 7526 products were included, with 47 % (n 3557) classified as 'healthy'. More than one-third of products displayed at least one nutrition claim and 15 % featured at least one health claim on the front-of-pack. Claims were found on one-third of 'less-healthy' products; 26 % of those products displayed nutrition claims and 7 % featured health claims. About 45 % of 'healthy' products displayed nutrition claims and 23 % featured health claims. Out of 7058 individual claims, the majority (69 %) were found on 'healthy' products. Cereals displayed the greatest proportion of nutrition and health claims (1503 claims on 564 products), of which one-third were displayed on 'less-healthy' cereals. Such claims could be misleading consumers' perceptions of nutritional quality of foods. It needs to be explored how current regulations on nutrition and health claims in New Zealand could be further strengthened (e.g. using the NPSC for nutrition claims, including general health claims as per the INFORMAS taxonomy) to ensure consumers are protected and not misled.

Disease management programmes (DMPs) were implemented in Germany in 2002. Their evaluation is required by law. Beyond the mandatory evaluation, a growing number of published studies evaluate the DMP for diabetes mellitus type 2 in a control-group design. As patients opt into the programme on a voluntary basis it is necessary to adjust the inherent selection bias between groups. The aim of this study is to review published studies which evaluate the diabetes DMP using a control-group design with respect to the methods used. A systematic literature review of electronic databases (PUBMED, Cochrane Library, EMBASE, MEDPILOT) and a hand search of reference lists of the relevant publications was conducted to identify studies evaluating the DMP diabetes mellitus in a control-group design. 8 studies were included in the systematic literature review. 4 studies gathered retrospective claims data from sickness funds, one from physician's records, one study used prospective data from ambulatory care, and 2 studies were based on one patient survey. Methods used for adjustment of selection bias included exact matching, matching using propensity score methods, age-adjusted and sex-separated analysis, and adjustment in a regression model/analysis of covariance. One study did not apply adjustment methods. The intervention period ranged from 1 day to 4 years. Considered outcomes of studies (surrogate parameter, diabetes complications, mortality, quality of life, and claim data) depended on the database. In the evaluation of the DMP diabetes mellitus based on a control-group design neither the database nor the methods used for selection bias adjustment were consistent in the available studies. Effectiveness of DMPs cannot be judged based on this review due to heterogeneity of study designs. To allow for a comprehensive programme evaluation standardised minimum requirements for the evaluation of DMPs in the control group design are required. © Georg Thieme Verlag KG Stuttgart · New York.

Muscle-related events, or myopathies, are a commonly reported adverse event associated with statin use. In June 2011, the US FDA released a Drug Safety Communication that provided updated product labeling with dosing restrictions for simvastatin to minimize the risk of myopathies. Our objective was to describe prescribing patterns of simvastatin in combination with medications known to increase the risk of myopathies following updated product labeling dosing restrictions in June 2011. A retrospective observational analysis was carried out, in which administrative claims data were utilized to identify prescribing patterns of simvastatin in combination with calcium channel blockers (CCBs) and other pre-specified drug therapies. Prescribing patterns were analyzed on a monthly basis 24 months prior to and 9 months following product label changes. Incidence of muscle-related events was also analyzed. In June 2011, a total of 60% of patients with overlapping simvastatin-CCB claims and 94% of patients with overlapping simvastatin-non-CCB claims were prescribed an against-label combination. As of March 2012, a total of 41% and 93% of patients continued to be prescribed against-label simvastatin-CCB and simvastatin-non-CCB combinations, respectively. The most commonly prescribed dose of simvastatin was 20 mg (39%). Against-label combinations were most commonly prescribed at a simvastatin dose of 40 mg (56%). Amlodipine was the most commonly prescribed CCB in combination with simvastatin (70%) and the most common CCB prescribed against-label (67%). Despite improvements in prescribing practices, many patients are still exposed to potentially harmful simvastatin combinations. Aggressive changes in simvastatin prescribing systems and processes are needed to improve compliance with FDA labeling to improve medication and patient safety.

To describe the development of the Claim Evaluation Tools, a set of flexible items to measure people's ability to assess claims about treatment effects. Methodologists and members of the community (including children) in Uganda, Rwanda, Kenya, Norway, the UK and Australia. In the iterative development of the items, we used purposeful sampling of people with training in research methodology, such as teachers of evidence-based medicine, as well as patients and members of the public from low-income and high-income countries. Development consisted of 4 processes: (1) determining the scope of the Claim Evaluation Tools and development of items; (2) expert item review and feedback (n=63); (3) cognitive interviews with children and adult end-users (n=109); and (4) piloting and administrative tests (n=956). The Claim Evaluation Tools database currently includes a battery of multiple-choice items. Each item begins with a scenario which is intended to be relevant across contexts, and which can be used for children (from age 10 and above), adult members of the public and health professionals. People with expertise in research methods judged the items to have face validity, and end-users judged them relevant and acceptable in their settings. In response to feedback from methodologists and end-users, we simplified some text, explained terms where needed, and redesigned formats and instructions. The Claim Evaluation Tools database is a flexible resource from which researchers, teachers and others can design measurement instruments to meet their own requirements. These evaluation tools are being managed and made freely available for non-commercial use (on request) through Testing Treatments interactive (testingtreatments.org).

This study investigated the real-world persistence rate and switches of teriparatide-treated patients using a claims database in Japan. The persistence rate of teriparatide at 12 months was 34.9%, and approximately one-third of the patients were not treated with any osteoporosis drugs after teriparatide. Improvement in persistence and switches are desired. We aimed to elucidate the persistence rates and switches before and after teriparatide treatment in real-world osteoporosis patients based on data from a medical claims database in Japan. We reviewed the records of patients with diagnoses of osteoporosis who were prescribed teriparatide at least once from January 2005 to June 2017. Patients with a follow-up ≤ 90 days before the first and ≤ 90 days after the last prescription of teriparatide were excluded. Discontinuation was defined as no treatment for > 90 days. We investigated treatment duration, compared characteristics of patients with persistence ≤ 12 and > 12 months, and osteoporotic medications before and after teriparatide by weekly or daily teriparatide. Among the 553 patients extracted for the study, 81.9% were women, 45.6% were aged ≥ 65 years, and 67.3% had a fracture. The most common fracture site was the spine (39.2%). The overall persistence rate of teriparatide > 12 months was 34.9% (weekly, 23.5%; daily, 43.1%). The subjects with persistence > 12 months comprised a higher proportion of women and they had a higher prevalence of rib and sternum fractures than those with ≤ 12 months. After teriparatide, 38.2% were switched to active vitamin D3, 35.1% to bisphosphonates, and 13.7% to denosumab allowing duplication. However, 34.0% of the patients were not switched to any subsequent medication for osteoporosis. Persistence rate over 12 months of teriparatide treatment was 34.9% in Japan. Approximately one-third of patients had no subsequent treatment immediately after teriparatide. Monitoring persistence and considering subsequent drugs for osteoporosis are necessary for teriparatide treatment.
Travel Distance and the Use of Inpatient Care among Patients with Schizophrenia

This study examines the variations in the use of inpatient care that can be explained by travel distance among patients with schizophrenia living in Taiwan. Data were drawn from the Psychiatric Inpatient Medical Claims Database. We used mediation analysis and multilevel analysis to identify associations. Travel distance did not significantly account for lower readmission rates after an index admission, but significantly explained the longer length of stay of an index admission by 9.3 days (P < 0.001, 85% of variation) between remote and non-remote regions. Policies are discussed aimed at reducing the impact of travel distance on rural mental health care through inter-disciplinary collaboration and telepsychiatry. PMID:18512144

Accident data play an important role in vehicle safety development. Accident data sources are generally limited in terms of how much information is provided on driver states and behaviour prior to an accident. However, the precise limitations vary between databases, due to differences in analysis focus and data collection procedures between organisations. If information about a specific accident can be retrieved from more than one data source it should be possible to combine the available information sets to facilitate data from one source to compensate for limitations in the other(s). To investigate the viability of such compensation, this study identified a set of accidents recorded in two different data sources. The first data source investigated was an accident mail survey and the second data source insurance claims documents consisting predominantly of insurance claims completed by the involved road users. An analysis of survey variables was compared to a case analysis including word data derived from the same survey and filed insurance claims documents. For each accident, the added value of having access to more than one source of information was assessed. To limit the scope of this study, three particular topics were investigated: available information on low vigilance (e.g., being drowsy, ill); secondary task distraction (e.g., talking with passengers, mobile phone use); and distraction related to the driving task (e.g., looking for approaching vehicles). Results suggest that for low vigilance and secondary task distraction, a combination of the mail survey and insurance claims documents provide more reliable and detailed pre-crash information than survey variables alone. However, driving related distraction appears to be more difficult to capture. In order to gain a better understanding of the above issues and how frequently they occur in accidents, the data sources and analysis methods suggested here may be combined with other investigation methods such as in-depth accident investigations and pre-crash data recordings.

Quality of Pharmaceutical Advertisements in Medical Journals: A Systematic Review
Othman, Noordin; Vitry, Agnes; Roughead, Elizabeth E.
2009-01-01
Background Journal advertising is one of the main sources of medicines information to doctors. Despite the availability of regulations and controls of drug promotion worldwide, information on medicines provided in journal advertising has been criticized in several studies for being of poor quality. However, no attempt has been made to systematically summarise this body of research. We designed this systematic review to assess all studies that have examined the quality of pharmaceutical advertisements for prescription products in medical and pharmacy journals. Methods and Findings Studies were identified via searching electronic databases, web library, search engine and reviewing citations (1950 – February 2006). Only articles published in English and examined the quality of information included in pharmaceutical advertisements for prescription products in medical or pharmacy journals were included. For each eligible article, a researcher independently extracted the data on the study methodology and outcomes. The data were then reviewed by a second researcher. Any disagreements were resolved by consensus. The data were analysed descriptively. The final analysis included 24 articles. The studies reviewed advertisements from 26 countries. The number of journals surveyed in each study ranged from four to 24 journals. Several outcome measures were examined including references and claims provided in advertisements, availability of product information, adherence to codes or guidelines and presentation of risk results. The majority of studies employed a convenience-sampling method. Brand name, generic name and indications were usually provided. Journal articles were commonly cited to support pharmaceutical claims. Less than 67% of the claims were supported by a systematic review, a meta-analysis or a randomised control trial. Studies that assessed misleading claims had at least one advertisement with a misleading claim. Two studies found that less than 28% of claims were unambiguous clinical claims. Most advertisements with quantitative information provided risk results as relative risk reduction. Studies were conducted in 26 countries only and then the generalizability of the results is limited. Conclusions Evidence from this review indicates that low quality of journal advertising is a global issue. As information provided in journal advertising has the potential to change doctors' prescribing behaviour, ongoing efforts to increase education about drug promotion are crucial. The results from our review suggest the need for a global pro-active and effective regulatory system to ensure that information provided in medical journal advertising is supporting the quality use of medicines.

Health care utilization databases have been increasingly used for studies of rheumatoid arthritis (RA). However, the accuracy of RA diagnoses in these data has been inconsistent. Using medical records and a standardized abstraction form, we examined the positive predictive value (PPV) of several algorithms to define RA diagnosis using claims data: A) at least two visits coded for RA (ICD-9, 714); B) at least three visits coded for RA; and C) at least two visits to a rheumatologist for RA. We also calculated the PPVs for the subgroups identified by these algorithms combined with pharmacy claims data for at least one disease-modifying anti-rheumatic drug (DMARD) prescription. We invited 9,482 Medicare beneficiaries with pharmacy benefits in Pennsylvania to participate; 2% responded and consented for review of their medical records. There was no difference in characteristics between respondents and non-respondents. Using 'RA diagnosis per rheumatologists' as the gold standard, the PPVs were 55.7% for at least two claims coded for RA, 65.5% for at least three claims for RA, and 66.7% for at least two rheumatology claims for RA. The PPVs of these algorithms in patients with at least one DMARD prescription increased to 86.2%-88.9%. When fulfillment of 4 or more of the ACR RA criteria was used as the gold standard, the PPVs of the algorithms combined with at least one DMARD prescriptions were 55.6%-60.7%. To accurately identify RA patients in health care utilization databases, algorithms that include both diagnosis codes and DMARD prescriptions are recommended.

Before preventive actions can be suggested for sports injuries at the national level, a solid surveillance system is required in order to study their epidemiology, risk factors and mechanisms. There are guidelines for sports injury data collection and classifications in the literature for that purpose. In Sweden, 90% of all athletes (57/70 sports federations) are insured with the same insurance company and data from their database could be a foundation for studies on acute sports injuries at the national level. To evaluate the usefulness of sports injury insurance claims data in sports injury surveillance at the national level. A database with 27 947 injuries was exported to an Excel file. Access to the corresponding text files was also obtained. Data were reviewed on available information, missing information and dropouts. Comparison with ASIDD (Australian Sports Injury Data Dictionary) and existing consensus statements in the literature (football (soccer), rugby union, tennis, cricket and thoroughbred horse racing) was performed in a structured manner. Comparison with ASIDD showed that 93% of the suggested data items were present in the database to at least some extent. Compliance with the consensus statements was generally high (13/18). Almost all claims (83%) contained text information concerning the injury. Relatively high-quality sports injury data can be obtained from a specific insurance company at the national level in Sweden. The database has the potential to be a solid base for research on acute sports injuries in different sports at the national level. Published by the BMJ Publishing Group Limited.

Integrative medicine is claimed to improve symptoms of lupus nephritis. No systematic reviews have been performed for the application of integrative medicine for lupus nephritis on patients with systemic lupus erythematosus (SLE). Thus, this review will aim to evaluate the current evidence on the efficacy of integrative medicine for the management of lupus nephritis in patients with SLE. The following electronic databases will be searched for studies published from their dates of inception February 2018: Medline, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL), as well as 6 Korean medical databases (Korea Med, the Oriental Medicine Advanced Search Integrated System [OASIS], DBpia, the Korean Medical Database [KM base], the Research Information Service System [RISS], and the Korean Studies Information Services System [KISS]), and 1 Chinese medical database (the China National Knowledge Infrastructure [CNKI]). Study selection, data extraction, and assessment will be performed independently by 2 researchers. The risk of bias (ROB) will be assessed using the Cochrane ROB tool. This systematic review will be published in a peer-reviewed journal and disseminated both electronically and in print. The review will be updated to inform and guide healthcare practice and policy.

The duration of oral antibiotic acne therapy for adolescents compared with guidelines was recently investigated; however it was uncertain if duration of antibiotics for adult acne therapy differed. This study aimed to evaluate duration of oral antibiotics for adult acne compared with guidelines and determine possible cost-savings. This was a retrospective cohort study of MarketScan Commercial Claims and Encounters database that incorporated claims data to determine duration and costs of antibiotic treatment among adults ages 21 years and older. Of 17,448 courses, 84.5% (14,737) aligned with duration guidelines, although 12,040 (69.0%) courses did not include concomitant topical retinoid therapy. Mean savings of $592.26 per person could result if prolonged courses met guidelines. Mean (median) costs of generic and branded formulations for the most frequent course duration (90-179 days) were $103.77 ($54.27) and $1421.61 ($1462.25), respectively. Actual patient prescription adherence is uncertain and database lacks information regarding acne severity, patient physical characteristics, and clinical outcomes. The majority of oral antibiotic course durations follow guidelines, although topical retinoids are underused. Costs of antibiotic therapy were lower for shorter courses and those using generic medications; the cost-effectiveness of these modifications has not been investigated.

Patients with rheumatoid arthritis (RA) commonly switch between tumor necrosis factor (TNF) inhibitors after failing to control disease activity. Much of the clinical data that support switching to a second TNF agent when one agent fails to work has come from small, short-term studies. We utilized a US insurance claims database to determine patterns of use such as dose escalation, time to discontinuation, and switching between TNF inhibitors in patients with RA. A retrospective analysis was performed using an insurance claims database in the US from 2000 to 2005. TNF inhibitor use, time to switch, dose escalation, and continuation times were analyzed in patients with RA. Nine thousand seventy-four patients with RA started TNF inhibitors during the period 2000 to 2005. Etanercept was the most commonly used TNF inhibitor; infliximab had the highest duration of continuation, about 50% at 2 years. In addition, infliximab showed higher rates of dose escalation compared to etanercept and adalimumab. For all TNF inhibitors, time to switching decreased from 2000 to 2005. TNF inhibitor use patterns changed from 2000 to 2005, with more frequent changes among the different TNF inhibitors and a shorter duration of treatment before the change. Only about 50% of TNF inhibitors are still continued at 2 years, reflecting the difference between randomized clinical trials and real-world experience.

To study the contemporary, real-world clinical and economic burden associated with angina after percutaneous coronary intervention (PCI). Angina adversely affects quality of life and medical costs, yet data on real-world prevalence of angina following PCI and its associated economic consequences are limited. In a multi-payer administrative claims database, we identified adults with incident inpatient PCI admissions between 2008 and 2011 who had at least 12 months of continuous medical and pharmacy benefits before and after the procedure. Patients were followed for up to 36 months. Using claims, we ascertained post-PCI outcomes: angina or chest pain, acute myocardial infarction, acute coronary syndrome, repeat PCI, healthcare service utilization, and costs. Among 51,710 study patients (mean age 61.8, 72% male), post-PCI angina or chest pain was present in 28% by 12 months and 40% by 36 months. Compared with patients who did not experience chest pain, angina or ACS, total healthcare costs in the first year after the index PCI were 1.8 times greater for patients with angina or chest pain ($32,437 vs. $17,913, P < 0.001). These cost differentials continued to 36 months. Angina after PCI is a frequent and expensive outcome. Further research is needed to identify risk factors and potentially improve outcomes for post-PCI angina. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.
Sources of Safety Data and Statistical Strategies for Design and Analysis: Postmarket Surveillance.
Izem, Rima; Sanchez-Kam, Matilde; Ma, Haijun; Zink, Richard; Zhao, Yueqin
2018-03-01
Safety data are continuously evaluated throughout the life cycle of a medical product to accurately assess and characterize the risks associated with the product. The knowledge about a medical product's safety profile continually evolves as safety data accumulate. This paper discusses data sources and analysis considerations for safety signal detection after a medical product is approved for marketing. This manuscript is the second in a series of papers from the American Statistical Association Biopharmaceutical Section Safety Working Group. We share our recommendations for the statistical and graphical methodologies necessary to appropriately analyze, report, and interpret safety outcomes, and we discuss the advantages and disadvantages of safety data obtained from passive postmarketing surveillance systems compared to other sources. Signal detection has traditionally relied on spontaneous reporting databases that have been available worldwide for decades. However, current regulatory guidelines and ease of reporting have increased the size of these databases exponentially over the last few years. With such large databases, data-mining tools using disproportionality analysis and helpful graphics are often used to detect potential signals. Although the data sources have many limitations, analyses of these data have been successful at identifying safety signals postmarketing. Experience analyzing these dynamic data is useful in understanding the potential and limitations of analyses with new data sources such as social media, claims, or electronic medical records data.

Detailed reviews of closed malpractice claims have provided insights into the most common events resulting in litigation and helped improve anesthesia care. In the past 10 years, there have been multiple safety advancements in the practice of obstetric anesthesia. We investigated the relationship among contributing factors, patient injuries, and legal outcome by analyzing a contemporary cohort of closed malpractice claims where obstetric anesthesiology was the principal defendant. The Controlled Risk Insurance Company (CRICO) is the captive medical liability insurer of the Harvard Medical Institutions that, in collaboration with other insurance companies and health care entities, contributes to the Comparative Benchmark System database for research purposes. We reviewed all (N = 106) closed malpractice cases related to obstetric anesthesia between 2005 and 2015 and compared the following classes of injury: maternal death and brain injury, neonatal death and brain injury, maternal nerve injury, and maternal major and minor injury. In addition, settled claims were compared to the cases that did not receive payment. χ, analysis of variance, Student t test, and Kruskal-Wallis tests were used for comparison between the different classes of injury. The largest number of claims, 54.7%, involved maternal nerve injury; 77.6% of these claims did not receive any indemnity payment. Cases involving maternal death or brain injury comprised 15.1% of all cases and were more likely to receive payment, especially in the high range (P = .02). The most common causes of maternal death or brain injury were high neuraxial blocks, embolic events, and failed intubation. Claims for maternal major and minor injury were least likely to receive payment (P = .02) and were most commonly (34.8%) associated with only emotional injury. Compared to the dropped/denied/dismissed claims, settled claims more frequently involved general anesthesia (P = .03), were associated with delays in care (P = .005), and took longer to resolve (3.2 vs 1.3 years; P < .0001). Obstetric anesthesia remains an area of significant malpractice liability. Opportunities for practice improvement in the area of severe maternal injury include timely recognition of high neuraxial block, availability of adequate resuscitative resources, and the use of advanced airway management techniques. Anesthesiologists should avoid delays in maternal care, establish clear communication, and follow their institutional policy regarding neonatal resuscitation. Prevention of maternal neurological injury should be directed toward performing neuraxial techniques at the lowest lumbar spine level possible and prevention/recognition of retained neuraxial devices.

This study aimed to investigate national prescription trends of benzodiazepines (BZD) for adults between 2007 and 2011 using Health Insurance Review and Assessment Service (HIRA) database in South Korea. Data analysis was performed by claim unit or patient unit. For the analysis of patient unit, each claim was merged by the same patient. Defined daily dose (DDD) was used to analyze the data in terms of dose and periods of BZD prescription. We identified a total of 22,361,449 adult patients who had BZD prescription at least once in 1,989,263 claims during 5 years. The average national BZD prescription prevalence for 1 year was 23.7%, 7.9%, 4.7%, and 3.2% of >= 1 day supply, >= 30 days supply, >= 90 days supply, and >= 180 days supply, respectively. The trends for 5 years were very similar. Among study population, 87.7% visited only non-psychiatric departments and the most frequent indication was gastrointestinal related diseases. BZD consumption expressed as DDDs per 1,000 inhabitants per day was 109.2. BZD consumption tended to be ~ 4 x higher in elderly than that of non-elderly (268.6 vs. 60.0 in male and 367.7 vs. 90.9 in female). Our study indicated the possibilities for inappropriate prescription of BZD, and the limitation policy on continuous prescription over 30 days supply did not seem to be effective. The effective interventions including an educational program for appropriate prescription of BZD should be considered.

This study's objective was to describe characteristics, treatment patterns, and economic outcomes of type 2 diabetes mellitus (T2DM) patients initiating injectable antidiabetic medications in Japan. Adults (≥ 18 years) with T2DM, ≥ 2 claims for injectable antidiabetics between 1 August 2011 and 31 July 2015 (first claim = index date), no evidence of type 1 diabetes mellitus, ≤ 1 claim for insulin, no claims for GLP-1RA before index, and continuous enrollment for 6 months before (baseline) and 12 months after index (follow-up) were selected from the Japan Medical Center Database. Patient characteristics and outcomes during the baseline and follow-up periods were described overall and by provider, using the proxy setting of index medication [hospital (including outpatient departments) for specialists; clinic for general practitioner (GP)]. Of the 2683 patients included (mean age: 50 years, 67% male), 1879 (70%) initiated injectable antidiabetics with specialists and 804 (30%) with GPs. The specialist cohort had a significantly greater comorbidity burden, but lower HbA1c levels during baseline, and was more likely to receive intensified treatment at index than the GP cohort. Almost 40% of patients (almost 30% of GP cohort) did not use antidiabetics during baseline; the remaining patients received oral medications, primarily from GPs. During follow-up, patients used the index medication for approximately 7 months. Independent of specialist vs. GP setting, patients received antidiabetics and medications for T2DM-related comorbidities and complications during the baseline and follow-up periods from the same provider, primarily GPs. The overall average healthcare costs were ¥350,404 during baseline and ¥1,856,727 during follow-up. In Japan, most T2DM patients initiated injectable antidiabetics with specialists vs. GPs. There were considerable differences in characteristics of patients treated by specialists vs. GPs. After initiation, injectable antidiabetics were largely prescribed by GPs. Future research should evaluate the factors associated with different provider practices and communication channels between specialists and GPs to improve patient management. Eli Lilly and Co.

Women were required to have 12 months of continuous insurance coverage prior to the insertion (baseline) and at least 12-months after (follow-up). Discontinuation was defined as presence of an insurance claim for pregnancy-related services, hysterectomy, female sterilization, a claim for another contraceptive method, or removal of the index contraceptive without re-insertion within 30 days. Using Cox regression we examined the potential impact of ENG implant vs. LNG-IUS 13.5 on the likelihood for discontinuation after controlling for patient characteristics. A total of 3680 (mean age: 25.4 years) LNG-IUS 13.5 and 23,770 (mean age: 24.6 years) ENG implant users met the selection criteria. Prior to insertion, 56.6% of LNG-IUS 13.5 and 42.1% of ENG implant users had used contraceptives, with oral contraceptives being most common (LNG-IUS 13.5: 42.1%; ENG implant: 28.5%). Among users of LNG-IUS 13.5 and ENG implant, rates of discontinuation were similar during the 12-month follow-up (LNG-IUS 13.5: 24.9%; ENG implant: 24.0%). Regression results showed that women using LNG-IUS 13.5 vs. ENG implant had similar likelihood for discontinuation (hazard ratio: 0.97, 95% confidence interval: 0.90-1.05, p=.41). In the real-world US setting, women aged 18-44 using LNG-IUS 13.5 and ENG implant have similar discontinuation rates after 12 months. In the United States, women aged 18-44 using levonorgestrel intrauterine system (13.5 mg) and subdermal etonogestrel implant have similar discontinuation rates after 12 months.

Objective We describe and compare the availability and accessibility of administrative healthcare databases (AHDB) in several Asia-Pacific countries: Australia, Japan, South Korea, Taiwan, Singapore, China, Thailand, and Malaysia. Methods The study included hospital records, reimbursement databases, prescription databases, and data linkages. Databases were first identified through PubMed, Google Scholar, and the ISPOR database register. Database custodians were contacted. Six criteria were used to assess the databases and provided the basis for a tool to categorise databases into seven levels ranging from least accessible (Level 1) to most accessible (Level 7). We also categorised overall data accessibility for each country as high, medium, or low based on accessibility of databases as well as the number of academic articles published using the databases. Results Fifty-four administrative databases were identified. Only a limited number of databases allowed access to raw data and were at Level 7 [Medical Data Vision EBM Provider, Japan Medical Data Centre (JMDC) Claims database and Nihon-Chouzai Pharmacy Claims database in Japan, and Medicare, Pharmaceutical Benefits Scheme (PBS), Centre for Health Record Linkage (CHeReL), HealthLinQ, Victorian Data Linkages (VDL), SA-NT DataLink in Australia]. At Levels 3–6 were several databases from Japan [Hamamatsu Medical University Database, Medi-Trend, Nihon University School of Medicine Clinical Data Warehouse (NUSM)], Australia [Western Australia Data Linkage (WADL)], Taiwan [National Health Insurance Research Database (NHIRD)], South Korea [Health Insurance Review and Assessment Service (HIRA)], and Malaysia [United Nations University (UNU)-Casemix]. Countries were categorised as having a high level of data accessibility (Australia, Taiwan, and Japan), medium level of accessibility (South Korea), or a low level of accessibility (Thailand, China, Malaysia, and Singapore). In some countries, data may be available but accessibility was restricted based on requirements by data custodians. Conclusions Compared with previous research, this study describes the landscape of databases in the selected countries with more granularity using an assessment tool developed for this purpose. A high number of databases were identified but most had restricted access, preventing their potential use to support research. We hope that this study helps to improve the understanding of the AHDB landscape, increase data sharing and database research in Asia-Pacific countries. PMID:27123180

This study aimed to explore the predictors of the selection between brand name drug (BR) and generic drug (GE) and to clarify the quantitative relationship about selection. We identified "incident users" who dispensed statins between April 2008 and June 2011 in commercially databases consisted of dispensing claims databases (DCD) of out-of-hospital pharmacies and hospital claims databases (HCD) of in-house pharmacies in Japan. Predictors of the selection between BR and GE, including price difference (PD), the price of BR, their interaction and percent change of the price of GE relative to BR were explored by logistic regression using DCD and HCD separately. We extracted records of 670 patients who have opportunity for selection both BR and GE. Logistic regression analysis demonstrated that PD, the price of BR, interaction between them, and prescriber affiliation were factors significantly associated with the selection in the DCD; logit (p)=9.735-0.251×PD-0.071×the price of BR+0.002×PD×the price of BR-1.816×affiliation+0.220×gender-0.008×age+0.038×monthly medical fee. PD was inversely proportional to BR choice in DCD and lead to the opposite result in HCD. Numerical simulation of selection revealed that the quantitative relationships heavily depend on situations. PD and the price of BR are predictors of the selection between BR and GE interactively in out-of-hospital pharmacies, but not in in-house pharmacies of medical facilities. Results may support policies which increase the power of out-of-hospital pharmacies for selection. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Management of patients with neuroendocrine tumors of the gastrointestinal tract or pancreas (GEP-NENs) poses diagnostic and therapeutic challenges. This study described the medico-legal claims reported to a national governmental system that oversees compensation to patients with GEP-NENs Materials and Methods: An electronic search of the Norwegian System of Compensation to Patients database was performed to identify claims evaluated between 2005-2016. The clinical information and the medico-legal evaluation were reviewed. We identified seven patients, five women and two men, with a median age of 57 (range=47-73) years. Delayed diagnosis (median diagnostic delay of 18 (range=6-48) months) was the main cause for claims in six out of the seven patients). Four patients received financial compensation based on the claim judgement. This review of claims that were evaluated by the Norwegian System of Compensation to Patients showed that a timely diagnosis of GEP-NENs remains a clinical challenge.

Nanoscale science and engineering (NSE) have seen rapid growth and expansion in new areas in recent years. This paper provides an international patent analysis using the U.S. Patent and Trademark Office (USPTO) data searched by keywords of the entire text: title, abstract, claims, and specifications. A fraction of these patents fully satisfy the National Nanotechnology Initiative definition of nanotechnology (which requires exploiting specific phenomena and direct manipulation at the nanoscale), while others only make use of NSE tools and methods of investigation. In previous work we proposed an integrated patent analysis and visualization framework of patent content mapping for the NSE field and of knowledge flow pattern identification until 2002. In this paper, the results are updated for 2003, and the new trends are presented.

In 2001, the University of Michigan Health System (UMHS) implemented a novel medical error disclosure program. This study analyzes the effect of this program on gastroenterology (GI)-related claims and costs. This was a review of claims in the UMHS Risk Management Database (1990-2010), naming a gastroenterologist. Claims were classified according to pre-determined categories. Claims data, including incident date, date of resolution, and total liability dollars, were reviewed. Mean total liability incurred per claim in the pre- and post-implementation eras was compared. Patient encounter data from the Division of Gastroenterology was also reviewed in order to benchmark claims data with changes in clinical volume. There were 238,911 GI encounters in the pre-implementation era and 411,944 in the post-implementation era. A total of 66 encounters resulted in claims: 38 in the pre-implementation era and 28 in the post-implementation era. Of the total number of claims, 15.2% alleged delay in diagnosis/misdiagnosis, 42.4% related to a procedure, and 42.4% involved improper management, treatment, or monitoring. The reduction in the proportion of encounters resulting in claims was statistically significant (P=0.001), as was the reduction in time to claim resolution (1,000 vs. 460 days) (P<0.0001). There was also a reduction in the mean total liability per claim ($167,309 pre vs. $81,107 post, 95% confidence interval: 33682.5-300936.2 pre vs. 1687.8-160526.7 post). Implementation of a novel medical error disclosure program, promoting transparency and quality improvement, not only decreased the number of GI-related claims per patient encounter, but also dramatically shortened the time to claim resolution.

The absence of ongoing surveillance for childhood asthma in Montreal, Quebec, prompted the present investigation to assess the validity and practicality of administrative databases as a foundation for surveillance. To explore the consistency between cases of asthma identified through physician billings compared with hospital discharge summaries. Rates of service use for asthma in 1998 among Montreal children aged one, four and eight years were estimated. Correspondence between the two databases (physician billing claims versus medical billing claims) were explored during three different time periods: the first day of hospitalization, during the entire hospital stay, and during the hospital stay plus a one-day margin before admission and after discharge ('hospital stay +/- 1 day'). During 1998, 7.6% of Montreal children consulted a physician for asthma at least once and 0.6% were hospitalized with a principal diagnosis of asthma. There were no contemporaneous physician billings for asthma 'in hospital' during hospital stay +/- 1 day for 22% of hospitalizations in which asthma was the primary diagnosis recorded at discharge. Conversely, among children with a physician billing for asthma 'in hospital', 66% were found to have a contemporaneous in-hospital record of a stay for 'asthma'. Both databases of hospital and medical billing claims are useful for estimating rates of hospitalization for asthma in children. The potential for diagnostic imprecision is of concern, especially if capturing the exact number of uses is more important than establishing patterns of use.

Effective treatment for rheumatoid arthritis (RA) may lead to lower overall and RA-related healthcare utilization. We evaluated healthcare utilization before and after initiation of the tumor necrosis factor inhibitor etanercept in patients with moderate to severe RA. This retrospective cohort study used data from the MarketScan ® claims database. Data from adult patients with RA newly exposed to etanercept between January 1, 2010 and December 31, 2013 were analyzed. Patients had at least one inpatient or outpatient claim for RA and at least one claim for etanercept (first claim was index date). Etanercept compliance was determined on the basis of proportion of days covered (PDC). Primary outcome was change in overall and RA-related healthcare utilization in the year before and year after etanercept initiation. McNemar's test and paired t test, respectively, were used to determine statistical significance for dichotomous and continuous variables. Data from 6737 patients were analyzed; mean age was 49.8 years and 77.3% were female. Overall outpatient services, office visits, outpatient hospital services, laboratory visits, and emergency department visits were significantly lower in the post-index period compared to pre-index. RA-related pharmacotherapy use (oral corticosteroids, opioid analgesics, nonsteroidal anti-inflammatory drugs, and nonbiologic disease-modifying antirheumatic drugs) was significantly lower in the post-index period compared to pre-index. Rates of RA-related total joint arthroplasty, joint reconstructions, and soft tissue procedures were similar in pre-index and post-index periods. High etanercept compliance (PDC ≥80%) was associated with significantly lower rates of RA-related outpatient services, office visits, diagnostic imaging studies, and joint reconstructions compared with noncompliance. Overall healthcare utilization decreased after etanercept initiation. Patients who were most compliant with etanercept had significantly lower utilization than less compliant patients. Amgen, Inc.

Psoriasis is a multifactorial, inflammatory, skin disease associated with various comorbidities. The cost of those comorbidities is not well characterized. The present study assesses the incremental burden of comorbidities on healthcare resource utilization, direct costs and indirect costs associated with short-term disabilities among patients with psoriasis in the United States. A retrospective, U.S. cohort analysis was conducted using a large claims database. Adult psoriasis patients with at least two diagnoses of psoriasis during the years 2010 and 2011 (one psoriasis diagnosis had to happen in the year 2010) and with continuous enrollment of medical and pharmacy benefits in the years 2010 and 2011 were included. Psoriasis patients were categorized and compared according to the presence or absence of pre-selected comorbidities in the year 2010. Adjusted annual direct (costs associated with outpatient, emergency room, and inpatient claims, and outpatient pharmacy claims) and indirect costs (short-term disabilities) was assessed in patients with and without comorbidities using a regression analysis, controlling for age, gender, and psoriasis severity in year 2010. In total, 56,406 patients (mean [SD]) age, 51.6 [14.6] years) were included in the analysis. The most prevalent comorbidities were hypertension (34.3%), hyperlipidemia (33.5%), cardiovascular disease (17.7%), diabetes (14.2%), and psoriatic arthritis (9.9%). Psoriasis patients with comorbidities used more healthcare resources than those without comorbidities. The incidence rate ratio (IRR) (95% CI) for patients with cardiovascular disease was 1.5 (1.4 - 1.5) for outpatient visits, 2.6 (2.4 - 2.8) for hospitalizations, and 2.3 (2.2 - 2.5) for ER visits, showing higher IRRs across all three types of resource use. The mean annual adjusted direct cost differences (i.e., incremental adjusted costs) in psoriasis patients with and without comorbidities were $9914.3, $8386.5, and $8275.1 for psoriatic arthritis, peripheral vascular disease, and cardiovascular disease, respectively. The mean annual incremental adjusted indirect costs of short-term disabilities were $1333, $1195, $994.9, and $996.6 for cerebrovascular disease, obesity, peripheral vascular disease, and depression, respectively. The presence of comorbidities was associated with higher healthcare resource utilization and costs among patients with psoriasis.

Objective: Attention-deficit/hyperactivity disorder (ADHD) is linked to an increased risk of injury in children. This retrospective analysis evaluated the risk and type of injury associated with ADHD in adults. Method: Data were taken from the MarketScan databases, which provide details of health care claims and productivity data for individuals and their dependents with access to employer-sponsored health plans. Adults (aged 18–64 years) with ≥ 2 ADHD-related diagnostic claims (using ICD-9-CM codes) between 2002 and 2007 and evidence of ADHD treatment in 2006 (n = 31,752) were matched to controls without ADHD (1:3; n = 95,256) or individuals with a depression diagnosis (using ICD-9-CM codes; 1:1; n = 29,965). Injury claims were compared between cohorts, and multivariate analyses controlled for differences that remained after matching. Results: Injury claims were more common in individuals with ADHD than in non-ADHD controls (21.5% vs 15.7%; P < .0001) or individuals with depression (21.4% vs 20.5%; P = .008). Multivariate analyses indicated that the relative risk of injury claims was higher in individuals with ADHD than in the non-ADHD control (odds ratio [OR] = 1.32; 95% CI, 1.27–1.37; P < .01) and depression (OR = 1.13; 95% CI, 1.07–1.18; P < .01) groups. Injury claims increased total direct health care expenditure; total expenditures for ADHD patients with injuries were $6,482 compared with $3,722 for ADHD patients without injuries (P < .0001). Comparison of injury-related costs were similar between ADHD patients and non-ADHD controls ($1,109 vs $1,041, respectively), but higher for depression patients than for ADHD patients ($1,792 vs $1,084; P < .01). Injury claim was also associated with increased short-term disability expenditures, as ADHD patients with injury incurred higher mean cost than those without injury ($1,303 vs $620; P = .0001), but lower than those with injury in the depression cohort (vs $2,152; P = .0099) Conclusions: Adults with ADHD were more likely to incur injury claims than non-ADHD controls or adults with depression in this sample selected on the basis of claims data rather than clinical referrals. Most injuries were relatively minor; however, individuals with injuries incurred higher total direct health care costs than those without injuries. Furthermore, the ratio of indirect costs due to workplace absence to direct health care costs was higher for adults with ADHD than for adults with depression, demonstrating not only the impact of ADHD in the workplace, but also the importance of accounting for productivity data in calculating the true economic burden of ADHD in adults.

Patient support programs have a positive effect on adherence to therapy. Certolizumab pegol (CZP) is a tumor necrosis factor antagonist for the treatment of Crohn's disease. To assess, using real-world claims data, whether home health nurse assistance had an effect on patients' adherence to CZP and to measure its impact on health care use and costs. A retrospective analysis of medical and pharmacy claims data from the IQVIA Real-World Data Adjudicated Claims Database was conducted using data from January 1, 2007 through September 30, 2015. CZP patients with Crohn's disease were eligible to receive self-administration instructions from a nurse or nurse-administered CZP injections, or both. These services were provided by CIMplicity ® , a home health nurse program sponsored by UCB Pharma. Cohorts were based on patients with and without nurse assistance and were matched based on gender and categorical age. Adherence to CZP was determined using the medication possession ratio (MPR) and proportion of days covered (PDC). A Kaplan-Meier analysis was performed to compare time to discontinuation of CZP between the two cohorts. Multivariate regression analyses were performed, adjusting for additional covariates to compare the effect of CZP with and without nurse assistance on hospitalization and total health care costs. Patients with at least 12 months of continuous enrollment post-index date were evaluated for adherence to CZP (n=276 in each cohort). The mean and median PDC and MPR values were higher with nurse assistance than without. Time to discontinuation was significantly longer in patients who received CZP with nurse assistance than without ( P =0.0004). Results from the multivariate analyses showed a significant reduction in all-cause hospitalization (-55.8%; P =0.0026) and total health care costs (-14.3%; P =0.0045) with nurse assistance. This analysis suggests that home health nurse assistance increases adherence to CZP and reduces health care costs in patients with Crohn's disease.

Objective To characterize weight-loss claims and disclaimers present on websites for commercial weight-loss programs and compare them to results from published randomized controlled trials (RCT). Methods We performed a content analysis of all homepages and testimonials available on the websites of 24 randomly selected programs. Two team members independently reviewed each page and abstracted information from text and images to capture relevant content including demographics, weight loss, and disclaimers. We performed a systematic review to evaluate the efficacy of these programs by searching MEDLINE and Cochrane Database of Systematic Reviews, and abstracted mean weight change from each included RCT. Results Overall, the amount of weight loss portrayed in the testimonials was extreme across all programs examined (range median weight loss 10.7 to 49.5 kg). Only 10 out of the 24 programs had eligible RCTs. Median weight losses reported in testimonials exceeded that achieved by trial participants. Most programs with RCTs (78%) provided disclaimers stating that the testimonial's results were non-typical and/or giving a range of typical weight loss. Conclusion Weight loss claims within testimonials were higher than results from RCTs. Future studies should examine whether commercial programs' advertising practices influence patients' expectations or satisfaction with modest weight loss results. PMID:28865085
Secondary Use of Claims Data from the Austrian Health Insurance System with i2b2: A Pilot Study.
Endel, Florian; Duftschmid, Georg
2016-01-01
In conformity with increasing international efforts to reuse routine health data for scientific purposes, the Main Association of Austrian Social Security Organisations provides pseudonymized claims data of the Austrian health care system for clinical research. We aimed to examine, whether an integration of the corresponding database into i2b2 would be possible and provide benefits. We applied docker-based software containers and data transformations to set up the system. To assess the benefits of i2b2 we plan to reenact the task of cohort formation of an earlier research project. The claims database was successfully integrated into i2b2. The docker-based installation approach will be published as git repository. The assessment of i2b2's benefits is currently work in progress and will be presented at the conference. Docker enables a flexible, reproducible, and resource-efficient installation of i2b2 within the restricted environment implied by our highly secured target system. First preliminary tests indicated several potential benefits of i2b2 compared to the methods applied during the earlier research project.

To develop the infant and toddler disease score (IDS), a population-based predictive tool of morbidity status in infants and toddlers, based on data from administrative claims. A prospective cohort study was conducted, including 35,580 children less than 2 years of age in June 2003 from the French "ERASME" database (mean follow-up 13 months). The outcome variable was incident hospitalization during the follow-up year, that is, before the second birthday for infants and before the third for toddlers. Risk factors before inclusion (age, health care use, medications) were assessed in a 50% random sample (construction sample) by a logistic regression model. Beta coefficients were summed up to obtain the IDS. The IDS was then validated for the remaining 50% of the study population (validation sample). The major variables significantly associated with the outcome were long-term disability, younger age, and >or=1 hospitalization before inclusion. The risks of hospitalization estimated by the IDS were concordant in the construction and validation samples. The IDS is a useful index for the risk of hospitalization of infants and toddlers in relation to their morbidity status and may be used for adjustment in pharmacoepidemiologic studies using administrative claims databases.
Are foods with fat-related claims useful for weight management?
Schermel, Alyssa; Wong, Christina L; L'Abbé, Mary R
2016-01-01
Many consumers believe that foods labelled with fat claims (e.g. low fat) are lower in calories than comparable regular foods and are therefore helpful for weight management. However, it is unknown whether such foods are actually lower in calories. Our aims were to determine 1) the relative proportion of foods carrying fat claims among various food categories within the Canadian marketplace; and 2) whether foods with fat claims are actually lower in calories than comparable foods without claims. The Food Label Information Program 2010, a database of Canadian foods developed at the University of Toronto, was used to compare the calorie content of products with and without fat claims within a given food subcategory, as defined by Schedule M of the Food and Drug Regulations. Median differences of 25% or greater were deemed nutritionally significant, as that is the minimum difference required for comparative claims such as "reduced" and "lower" in the Food and Drug Regulations. Fat claims were present on up to 68% of products in a given food subcategory. Products with fat claims were not significantly lower in both fat and calories compared to comparable products without fat claims in more than half of the subcategories (24 out of 40) analyzed. Conversely, in 16 subcategories, foods with fat claims were at least 25% lower in calories; however, for many of these foods, the absolute difference in calories was small, i.e., for 9 of the 16 subcategories, the absolute difference between foods with and without fat claims was <50 calories, even though the relative percent difference was high. This research suggests that foods with fat claims may be misleading consumers and undermining their efforts to manage body weight or prevent obesity. Copyright © 2015 Elsevier Ltd.

Use of administrative medical databases in population-based research.
Gavrielov-Yusim, Natalie; Friger, Michael
2014-03-01
Administrative medical databases are massive repositories of data collected in healthcare for various purposes. Such databases are maintained in hospitals, health maintenance organisations and health insurance organisations. Administrative databases may contain medical claims for reimbursement, records of health services, medical procedures, prescriptions, and diagnoses information. It is clear that such systems may provide a valuable variety of clinical and demographic information as well as an on-going process of data collection. In general, information gathering in these databases does not initially presume and is not planned for research purposes. Nonetheless, administrative databases may be used as a robust research tool. In this article, we address the subject of public health research that employs administrative data. We discuss the biases and the limitations of such research, as well as other important epidemiological and biostatistical key points specific to administrative database studies.

Although Internet-based surveys are becoming more common, little is known about agreement between administrative claims data and Internet-based survey self- and proxy-reported health care resource utilization (HCRU) data. This analysis evaluated the level of agreement between self- and proxy-reported HCRU data, as recorded through an Internet-based survey, and administrative claims-based HCRU data. The Child and Household Influenza-Illness and Employee Function study collected self- and proxy-reported HCRU data monthly between November 2007 and May 2008. Data included the occurrence and number of visits to hospitals, emergency departments, urgent care centers, and outpatient offices for a respondent's and his or her household members' care. Administrative claims data from the MarketScan® Databases were assessed during the same time and evaluated relative to survey-based metrics. Only data for individuals with employer-sponsored health care coverage linkable to claims were included. The Kappa (κ) statistic was used to evaluate visit concordance, and the intraclass correlation coefficient was used to describe frequency consistency. Agreement for presence of a health care visit and the number of visits were similar for self- and proxy-reported HCRU data. There was moderate to substantial agreement related to health care visit occurrence between survey-based and claims-based HCRU data for inpatient, emergency department, and office visits (κ: 0.47-0.77). There was less agreement on health care visit frequencies, with intraclass correlation coefficient values ranging from 0.14 to 0.71. This study's agreement values suggest that Internet-based surveys are an effective method to collect self- and proxy-reported HCRU data. These results should increase confidence in the use of the Internet for evaluating disease burden. Copyright © 2012 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Oncology patient-reported claims: maximising the chance for success.
Kitchen, H; Rofail, D; Caron, M; Emery, M-P

To review Patient Reported Outcome (PRO) labelling claims achieved in oncology in Europe and in the United States and consider the benefits, and challenges faced. PROLabels database was searched to identify oncology products with PRO labelling approved in Europe since 1995 or in the United States since 1998. The US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) websites and guidance documents were reviewed. PUBMED was searched for articles on PRO claims in oncology. Among all oncology products approved, 22 were identified with PRO claims; 10 in the United States, 7 in Europe, and 5 in both. The language used in the labelling was limited to benefit (e.g. "…resulted in symptom benefits by significantly prolonging time to deterioration in cough, dyspnoea, and pain, versus placebo") and equivalence (e.g. "no statistical differences were observed between treatment groups for global QoL"). Seven products used a validated HRQoL tool; two used symptom tools; two used both; seven used single-item symptom measures (one was unknown). The following emerged as likely reasons for success: ensuring systematic PRO data collection; clear rationale for pre-specified endpoints; adequately powered trials to detect differences and clinically significant changes; adjusting for multiplicity; developing an a priori statistical analysis plan including primary and subgroup analyses, dealing with missing data, pooling multiple-site data; establishing clinical versus statistical significance; interpreting failure to detect change. End-stage patient drop-out rates and cessation of trials due to exceptional therapeutic benefit pose significant challenges to demonstrating treatment PRO improvement. PRO labelling claims demonstrate treatment impact and the trade-off between efficacy and side effects ultimately facilitating product differentiation. Reliable and valid instruments specific to the desired language, claim, and target population are required. Practical considerations include rationale for study endpoints, transparency in assumptions, and attention to subtle variations in data.

End-stage patient drop-out rates and cessation of trials due to exceptional therapeutic benefit pose significant challenges to demonstrating treatment PRO improvement. Conclusions: PRO labelling claims demonstrate treatment impact and the trade-off between efficacy and side effects ultimately facilitating product differentiation. Reliable and valid instruments specific to the desired language, claim, and target population are required. Practical considerations include rationale for study endpoints, transparency in assumptions, and attention to subtle variations in data. PMID:22276055

To determine the temporal relationship between vasectomy, varicocele, and hypogonadism diagnosis. Many young men undergo their first thorough genitourinary examination in their adult lives at the time of vasectomy consultation, providing a unique opportunity for diagnosis of asymptomatic varicoceles. Varicoceles have recently been implicated as a possible reversible contributor to hypogonadism. Hypogonadism may be associated with significant adverse effect, including decreased libido, impaired cognitive function, and increased cardiovascular events. Early diagnosis and treatment of hypogonadism may prevent these adverse sequelae. Data were collected from the Truven Health Analytics MarketScan database, a large outpatient claims database. We reviewed records between 2003 and 2010 for male patients between the ages of 25 and 50 years with International Classification of Diseases, Ninth Revision codes for hypogonadism, vasectomy, and varicocele, and queried dates of first claim. A total of 15,679 men undergoing vasectomies were matched with 156,790 men with nonvasectomy claims in the same year. Vasectomy patients were diagnosed with varicocele at an earlier age (40.9 vs 42.5 years; P=.009). We identified 224,817 men between the ages of 25 and 50 years with a claim of hypogonadism, of which 5883 (2.6%) also had a claim of varicocele. Men with hypogonadism alone were older at presentation compared with men with an accompanying varicocele (41.3 [standard deviation±6.5] vs 34.9 [standard deviation±6.1]; P<.001). Men undergoing vasectomies are diagnosed with varicoceles at a younger age than age-matched controls. Men with varicoceles present with hypogonadism earlier than men without varicoceles. Earlier diagnosis of varicocele at the time of vasectomy allows for earlier detection of hypogonadism. Copyright © 2014 Elsevier Inc. All rights reserved.

Asthma is associated with a substantial economic burden on the German Statutory Health Insurance. To determine costs and resource utilization associated with asthma and to analyze the impact of disease severity on subgroups based on age and gender. A claims database analysis from the statutory health insurance perspective was conducted. Patients with an ICD-10-GM code of asthma were extracted from a 10% sample of a large German sickness fund. Five controls for each asthma patient matched by age and gender were randomly selected from the same database. Costs and resource utilization were calculated for each individual in the asthma and control group. Incremental asthma-related costs were calculated as the mean cost difference. Based on prescribed asthma medication, patients were classified as intermittent or persistent. In addition, age groups of ≤ 5, 6-18, and >18 years were analyzed separately and gender differences were investigated. Overall, 49,668 individuals were included in the asthma group. On average, total annual costs per patient were €753 higher (p = 0.000) compared to the control group (€2,168 vs. €1,415). Asthma patients had significantly higher (p = 0.000) outpatient (€217), inpatient (€176), and pharmacy costs (€259). Incremental asthma-related total costs were higher for patients with persistent asthma compared to patients with intermittent asthma (€1,091 vs. €408). Women aged >18 years with persistent asthma had the highest difference in costs compared to their controls (€1,207; p < 0.0001). Corresponding healthcare resource utilization was significantly higher in the asthma group (p = 0.000). The treatment of asthma is associated with an increased level of healthcare resource utilization and significantly higher healthcare costs. Asthma imposes a substantial economic burden on sickness funds.

The analysis of flood exposure at a national scale for the French insurance market must combine the generation of a probabilistic event set of all possible but not yet occurred flood situations with hazard and damage modeling. In this study, hazard and damage models are calibrated on a 1995-2012 historical event set, both for hazard results (river flow, flooded areas) and loss estimations. Thus, uncertainties in the deterministic estimation of a single event loss are known before simulating a probabilistic event set. To take into account at least 90% of the insured flood losses, the probabilistic event set must combine the river overflow (small and large catchments) with the surface runoff due to heavy rainfall, on the slopes of the watershed. Indeed, internal studies of CCR claim database has shown that approximately 45% of the insured flood losses are located inside the floodplains and 45% outside. 10% other percent are due to seasurge floods and groundwater rise. In this approach, two independent probabilistic methods are combined to create a single flood loss distribution: generation of fictive river flows based on the historical records of the river gauge network and generation of fictive rain fields on small catchments, calibrated on the 1958-2010 Météo-France rain database SAFRAN. All the events in the probabilistic event sets are simulated with the deterministic model. This hazard and damage distribution is used to simulate the flood losses at the national scale for an insurance company (MACIF) and to generate flood areas associated with hazard return periods. The flood maps concern river overflow and surface water runoff. Validation of these maps is conducted by comparison with the address located claim data on a small catchment (downstream Argens).

The Occupational Disease Surveillance System (ODSS) was established in Ontario, Canada by linking a cohort of workers with data created from Workplace Safety and Insurance Board (WSIB) claims to administrative health databases. The aim of this study was to use ODSS to identify high-risk industry and occupation groups for lung cancer in Ontario. Workers in the WSIB lost time claims database were linked to the Ontario Cancer Registry using subjects' health insurance numbers, name, sex, birthdate and death date (if applicable). Several occupations and industries known to be at increased risk were outlined a priori to examine whether ODSS could replicate these associations. Age-adjusted, sex-stratified Cox proportional hazard models compared the risk of lung cancer within one industry/occupation versus all other groups in the cohort. Workers with a lung cancer diagnosis prior to cohort entry were excluded for analysis, leaving 2 187 762 workers for analysis. During the 1983 to 2014 follow-up, 34 661 workers in the cohort were diagnosed with lung cancer. Among expected high-risk industries, elevated risks were observed among workers in quarries/sand pits and construction industries for both sexes, and among males in metal mines, iron foundries, non-metallic mineral products industries and transportation industries. Excess risk was also observed among occupations in drilling/blasting, other mining/quarrying, mineral ore treating, excavating/grading/paving, truck driving, painting, bus driving and construction. This current surveillance system identified several established high-risk groups for lung cancer and could be used for ongoing surveillance of occupational lung cancer in Ontario. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

To determine the most appropriate methods for estimating the prevalence and incidence of coronary heart disease (CHD), the associated risk factors, and health care costs in a corporate setting. Using medical insurance claims data for the period of 2005-2009 from 18 companies in the Thomson Reuters MarketScan reg database, we evaluated three alternative methods. Prevalence of CHD ranged from 2.1% to 4.0% using a method requiring a second confirmatory claim. Annual incidence of CHD ranged from 1.0% to 1.6% using a method requiring 320 days of benefits enrollment in the previous year, and one claim for a diagnosis of CHD. Alternative methods for determining the epidemiologic and cost burden of CHD using insurance claims data were explored. These methods can inform organizations that want to quantify the health and cost burden of various diseases common among an employed population.

Taiwan's global budgeting for hospital health care, in comparison to other countries, assigns a regional budget cap for hospitals' medical benefits claimed on the basis of fee-for-service (FFS) payments. This study uses a stays-hospitals-years database comprising acute myocardial infarction inpatients to examine whether the reimbursement policy mitigates the medical benefits claimed to a third-payer party during 2000-2008. The estimated results of a nested random-effects model showed that hospitals attempted to increase their medical benefit claims under the influence of initial implementation of global budgeting. The magnitudes of hospitals' responses to global budgeting were significantly attributed to hospital ownership, accreditation status, and market competitiveness of a region. The results imply that the regional budget cap superimposed on FFS payments provides only blunt incentive to the hospitals to cooperate to contain medical resource utilization, unless a monitoring mechanism attached with the payment system.

Nutrient claims are a commonly used marketing tactic, but the association between claims and nutritional quality of products is unknown. The objective of this study was to examine trends in the proportion of packaged food and beverage purchases with a nutrient claim, whether claims are associated with improved nutritional profile, and whether the proportion of purchases with claims differs by race/ethnicity or socioeconomic status. This cross-sectional study examined nutrient claims on more than 80 million food and beverage purchases from a transaction-level database of 40,000 US households from 2008 to 2012. χ 2 Tests were used to examine whether the proportion of purchases with a low/no-content claim changed over time or differed by race/ethnicity or household socioeconomic status. Pooled transactions were examined using t-tests to compare products' nutritional profiles overall and by food and beverage group. Thirteen percent of food and 35% of beverage purchases had a low-content claim. Prevalence of claims among purchases did not change over time. Low-fat claims were most prevalent for both foods and beverages (10% and 19%, respectively), followed by low-calorie (3% and 9%), low-sugar (2% and 8%), and low-sodium (2% for both) claims. Compared to purchases with no claim, purchases with any low-content claim had lower mean energy, total sugar, total fat, and sodium densities. However, the association between particular claim types and specific nutrient densities varied substantially, and purchases featuring a given low-content claim did not necessarily offer better overall nutritional profiles or better profiles for the claimed nutrient, relative to products without claims. In addition, there was substantial heterogeneity in associations between claims and nutrient densities within food and beverage groups. Variations in nutrient density by claim type and food and beverage group suggests that claims may have differential utility for certain foods or nutrients and, in some cases, may mislead about the overall nutritional quality of the food.

To estimate biologic cost per effectively treated patient with rheumatoid arthritis (RA) using a claims-based algorithm for effectiveness. Patients with RA aged 18-63 years in the IMS PharMetrics Plus database were categorized as effectively treated if they met all six criteria: (1) a medication possession ratio ≥80% (subcutaneous) or at least as many infusions as specified in US labeling (intravenous); (2) no biologic dose increase; (3) no biologic switch; (4) no new non-biologic disease-modifying anti-rheumatic drug; (5) no new or increased oral glucocorticoid; and (6) ≤1 glucocorticoid injection. Biologic cost per effectively treated patient was defined as total cost of the index biologic (drug plus intravenous administration) divided by the number of patients categorized by the algorithm as effectively treated. Similar methods were used for the index biologic in the second year and for a second biologic after a switch. Rates that the index biologic was categorized as effective in the first year were 31.0% etanercept (2243/7247), 28.6% adalimumab (1426/4991), 28.6% abatacept (332/1160), 27.2% golimumab (71/261), and 20.2% infliximab (474/2352). Mean biologic cost per effectively treated patient, per the algorithm, was $50,141 etanercept, $53,386 golimumab, $56,942 adalimumab, $73,516 abatacept, and $114,089 infliximab. Biologic cost per effectively treated patient, using this algorithm, was lower for patients who continued the index biologic in the second year and higher after switching. When a claims-based algorithm was applied to a large commercial claims database, etanercept was categorized as the most effective and had the lowest estimated 1-year biologic cost per effectively treated patient. This proxy for effectiveness from claims databases was validated against a clinical effectiveness scale, but analyses of the second year or the year after a biologic switch were not included in the validation. Costs of other medications were not included in cost calculations.

This drug utilization study aimed to investigate prescription patterns and trends for anti-rheumatic drug use in Japanese patients with rheumatoid arthritis (RA), clarifying if patients with RA in Japan are being treated according to EULAR recommendations and ACR guidelines. We used a large-scale claims database consisting of the medical claims of employee health insurance recipients, which included approximately one million insured people. The claims data for incident 5,126 patients with diagnosis codes of RA between January 1, 2005 and October 31, 2011 were analyzed. The number of patients who received disease modifying anti-rheumatic drugs (DMARDs) including biologics as initial therapy was 629 (12.3 %), while the others received non-DMARD therapy only. During the study period, use of methotrexate (MTX) and biologics as first-line drugs increased from 1.9 to 8.0 % and from 0 to 1.6 %, respectively (p < 0.001 for both), while that of non-steroidal anti-inflammatory drugs (NSAIDs) decreased (p = 0.004). Time from first RA diagnosis to the start of treatment with DMARDs decreased significantly from 2005 to 2010. These findings suggest that many early RA patients in Japan do not yet receive aggressive treatment, albeit that this prescribing practice has gradually changed to better comply with clinical recommendations. The current, obsolete Japanese RA guidelines require urgent updating to reflect the most recent knowledge and care with effective treatment modalities.

Electronic healthcare databases (EHDs) are used increasingly for post-marketing drug safety surveillance and pharmacoepidemiology in Europe and North America. However, few studies have examined the potential of these data sources in China. Three major types of EHDs in China (i.e., a regional community-based database, a national claims database, and an electronic medical records [EMR] database) were selected for evaluation. Forty core variables were derived based on the US Mini-Sentinel (MS) Common Data Model (CDM) as well as the data features in China that would be desirable to support drug safety surveillance. An email survey of these core variables and eight general questions as well as follow-up inquiries on additional variables was conducted. These 40 core variables across the three EHDs and all variables in each EHD along with those in the US MS CDM and Observational Medical Outcomes Partnership (OMOP) CDM were compared for availability and labeled based on specific standards. All of the EHDs' custodians confirmed their willingness to share their databases with academic institutions after appropriate approval was obtained. The regional community-based database contained 1.19 million people in 2015 with 85% of core variables. Resampled annually nationwide, the national claims database included 5.4 million people in 2014 with 55% of core variables, and the EMR database included 3 million inpatients from 60 hospitals in 2015 with 80% of core variables. Compared with MS CDM or OMOP CDM, the proportion of variables across the three EHDs available or able to be transformed/derived from the original sources are 24-83% or 45-73%, respectively. These EHDs provide potential value to post-marketing drug safety surveillance and pharmacoepidemiology in China. Future research is warranted to assess the quality and completeness of these EHDs or additional data sources in China.

To report utilization trends in diagnostic imaging among commercially insured Massachusetts residents from 2009 to 2013. Current Procedural Terminology codes were used to identify diagnostic imaging claims in the Massachusetts All-Payer Claims Database for the years 2009 to 2013. We reported utilization and spending annually by imaging modality using total claims, claims per 1,000 individuals, total expenditures, and average per claim payments. The number of diagnostic imaging claims per insured MA resident increased only 0.6% from 2009 to 2013, whereas nonradiology claims increased by 6% annually. Overall diagnostic imaging expenditures, adjusted for inflation, were 27% lower in 2009 than 2013, compared with an 18% increase in nonimaging expenditures. Average payments per claim were lower in 2013 than 2009 for all modalities except nuclear medicine. Imaging procedure claims per 1,000 MA residents increased from 2009 to 2013 by 13% in MRI, from 147 to 166; by 17% in ultrasound, from 453 to 530; and by 12% in radiography (x-ray), from 985 to 1,100. However, CT claims per 1,000 fell by 37%, from 341 to 213, and nuclear medicine declined 57%, from 89 claims per 1,000 to 38. Diagnostic imaging utilization exhibited negligible growth over the study period. Diagnostic imaging expenditures declined, largely the result of falling payments per claim in most imaging modalities, in contrast with increased utilization and spending on nonimaging services. Utilization of MRI, ultrasound, and x-ray increased from 2009 to 2013, whereas CT and nuclear medicine use decreased sharply, although CT was heavily impacted by billing code changes.

Medical research using governments' health claims databases: with or without patients' consent?
Tsai, Feng-Jen; Junod, Valérie
2018-03-01
Taking advantage of its single-payer, universal insurance system, Taiwan has leveraged its exhaustive database of health claims data for research purposes. Researchers can apply to receive access to pseudonymized (coded) medical data about insured patients, notably their diagnoses, health status and treatments. In view of the strict safeguards implemented, the Taiwanese government considers that this research use does not require patients' consent (either in the form of an opt-in or in the form of an opt-out). A group of non-governmental organizations has challenged this view in the Taiwanese Courts, but to no avail. The present article reviews the arguments both against and in favor of patients' consent for re-use of their data in research. It concludes that offering patients an opt-out would be appropriate as it would best balance the important interests at issue.

Probiotics are microorganisms that have a beneficial effect on the health of the host. However, before these effects can be referred to as beneficial to human health, such claims need to be evaluated by regulatory institutes such as the European Food Safety Authority (EFSA). The EFSA Panel on Dietetic Products, Nutrition and allergies (NDA) has published their opinions regarding health claims including probiotics, most of which were rejected in the past years. Using the EFSA database, the NDA dossiers published between 2005 and 2013 were analysed to provide an overview on what grounds certain health effects were accepted as beneficial and others not. The NDA Panel distinguishes between claims that are definitely beneficial, possibly beneficial or non-beneficial to human health. Overall, 78% of all analysed health claims are considered by the NDA Panel as (possibly) beneficial to human health, in particular the gut health effects. Since, in many cases, the scientific substantiation of a particular health claim was deemed insufficient, most applications were turned down. For future health claim applications concerning probiotics to be successful, they should include specific statements on what exactly the microorganism affects, and the scientific substantiation of the particular health claim should be based on the targeted (general) population.
Obesity and trends in malpractice claims for physicians and surgeons.

The increasing prevalence of obesity has altered the practice of medicine and surgery, with the emergence of new operations and medications. We hypothesized that the landscape of medical malpractice claims has also changed. We queried the Physician Insurers Association of American database for 1990 through 1999 and 2000 through 2009 for cases corresponding to International Classification of Diseases, 9th edition, codes for obesity. We extracted adjudicatory outcome, closed and paid claims data, indemnity payments, primary alleged error codes, National Association of Insurance Commissioners severity of injury class, procedural codes, and medical specialty data. A total of 411 obesity claims were filed from 1990 to 1999 and 1,591 obesity claims were filed from 2000 to 2009. General surgery was the specialty with the greatest number of obesity claims from 1990 to 1999 and was second to family practice for 2000 to 2009. Although the percentage of paid general surgery obesity claims has decreased significantly from 69% in 1990-1999 to 36% in 2000-2009, the mean indemnity payments have increased substantially ($94,000 to $368,000). Recently, the percentage of paid general surgery obesity claims has significantly decreased; however, individual and total indemnity payments have increased. Obesity continues to impact general surgery malpractice substantially. Efforts to manage this component of physician and hospital practices must continue. Copyright © 2013 Mosby, Inc.

Participation of local communities in the Measurement, Reporting and Verification (MRV) of forest changes has been promoted as a strategy that lowers the cost of MRV and increases their engagement with REDD+. This systematic review of literature assessed the claims of participatory MRV (PMRV) in achieving REDD+ outcomes. We identified 29 PMRV publications that consisted of 20 peer-reviewed and 9 non peer-reviewed publications, with 14 publications being empirically based studies. The evidence supporting PMRV claims was categorized into empirical finding, citation or assumption. Our analysis of the empirical studies showed that PMRV projects were conducted in 17 countries in three tropical continents and across various forest and land tenure types. Most of these projects tested the feasibility of participatory measurement or monitoring, which limited the participation of local communities to data gathering. PMRV claims of providing accurate local biomass measurements and lowering MRV cost were well-supported with empirical evidence. Claims that PMRV supports REDD+ social outcomes that affect local communities directly, such as increased environmental awareness and equity in benefit sharing, were supported with less empirical evidence than REDD+ technical outcomes. This may be due to the difficulties in measuring social outcomes and the slow progress in the development and implementation of REDD+ components outside of experimental research contexts. Although lessons from other monitoring contexts have been used to support PMRV claims, they are only applicable when the enabling conditions can be replicated in REDD+ contexts. There is a need for more empirical evidence to support PMRV claims on achieving REDD+ social outcomes, which may be addressed with more opportunities and rigorous methods for assessing REDD+ social outcomes. Integrating future PMRV studies into local REDD+ implementations may help create those opportunities, while increasing the participation of local communities as local REDD+ stakeholders. Further development and testing of participatory reporting framework are required to integrate PMRV data with the national database. Publication of empirical PMRV studies is encouraged to guide when, where and how PMRV should be implemented. PMID:27812110

Objective To characterize demographics, clinical characteristics, and treatment patterns of patients with cluster headache (CH). Background CH is an uncommon trigeminal autonomic cephalalgia with limited evidence‐based treatment options. Patients suffer from extremely painful unilateral headache attacks and autonomic symptoms with episodic and chronic cycles. Design/Methods This retrospective analysis used insurance claims from Truven Health Analytics MarketScan® research databases from 2009 to 2014. Two cohorts were compared: CH patients (with ≥2 CH claims) were propensity score matched with 4 non‐headache controls, all with continuous enrollment for 12 months before and after the date of first CH claim or matched period among controls. Results CH patients (N = 7589) were mainly male (57.4%) and 35‐64 years old (73.2%), with significantly more claims for comorbid conditions vs controls (N = 30,341), including depressive disorders (19.8% vs 10.0%), sleep disturbances (19.7% vs 9.1%), anxiety disorders (19.2% vs 8.7%), and tobacco use disorders (12.8% vs 5.3%), with 2.5 times greater odds of suicidal ideation (all P < .0001). Odds of drug dependence were 3‐fold greater among CH patients (OR = 2.8 [95% CI 2.3‐3.4, P < .0001]). CH patients reported significantly greater use of prescription medications compared with controls; 25% of CH patients had >12 unique prescription drug claims. Most commonly prescribed drug classes for CH patients included: opiate agonists (41%), corticosteroids (34%), 5HT‐1 agonists (32%), antidepressants (31%), NSAIDs (29%), anticonvulsants (28%), calcium antagonists (27%), and benzodiazepines (22%). Only 30.4% of CH patients received recognized CH treatments without opioids during the 12‐month post‐index period. These patients were less likely to visit emergency departments or need hospitalizations (26.8%) as compared to CH patients with no pharmacy claims for recognized CH treatments or opioids (33.6%; P < .0001). Conclusions The burden of CH is associated with significant co‐morbidity, including substance use disorders and suicidal ideation, and treatment patterns indicating low use of recognized CH treatments.

Real-world data comparing tofacitinib with biologic disease-modifying antirheumatic drugs (bDMARDs) are limited. To compare characteristics, treatment patterns, and costs of patients with rheumatoid arthritis (RA) receiving tofacitinib versus the most common bDMARDs (adalimumab [ADA], etanercept [ETN], and abatacept [ABA]) following a single bDMARD in a U.S. administrative claims database. This study was a retrospective cohort analysis of patients aged ≥ 18 years with an RA diagnosis (ICD-9-CM codes 714.0x-714.4x; 714.81) and 1 previous bDMARD filling ≥ 1 tofacitinib or bDMARD claim in the Truven MarketScan Commercial and Medicare Supplemental claims databases (November 1, 2012-October 31, 2014). Monotherapy was defined as absence of conventional synthetic DMARDs within 90 days post-index. Persistence was evaluated using a 60-day gap. Adherence was assessed using proportion of days covered (PDC). RA-related total, pharmacy, and medical costs were evaluated in the 12-month pre- and post-index periods. Treatment patterns and costs were adjusted using linear models including a common set of clinically relevant variables of interest (e.g., previous RA treatments), which were assessed separately using t-tests and chi-squared tests. Overall, 392 patients initiated tofacitinib; 178 patients initiated ADA; 118 patients initiated ETN; and 191 patients initiated ABA. Tofacitinib patients were older versus ADA patients (P = 0.0153) and had a lower proportion of Medicare supplemental patients versus ABA patients (P = 0.0095). Twelve-month pre-index bDMARD use was greater in tofacitinib patients (77.6%) versus bDMARD cohorts (47.6%-59.6%). Tofacitinib patients had greater 12-month pre-index RA-related total costs versus bDMARD cohorts (all P < 0.0001) and greatest index use of monotherapy (P = 0.0080 vs. ABA). A similar (all P > 0.10) proportion of patients were persistent with tofacitinib (42.6%) versus ADA (37.6%), ETN (42.4%), and ABA (43.5%). Mean PDC was 0.55 for tofacitinib versus 0.57 (ADA), 0.59 (ETN), and 0.44 (ABA; P = 0.0003). Adjusted analyses generated similar findings to the unadjusted treatment patterns. Tofacitinib had lower adjusted 12-month post-index mean RA-related total costs ($23,568) versus ADA ($29,278; P < 0.0001), ETN ($26,885; P = 0.0248), and ABA ($30,477; P < 0.0001). In this study, tofacitinib was more commonly used as monotherapy and yielded at least comparable persistence and adherence with lower adjusted mean RA-related total costs versus ADA, ETN, and ABA. Further analysis is warranted given the greater 12-month pre-index bDMARD use and RA-related costs for tofacitinib versus bDMARDs. This study was sponsored by Pfizer.

Relapse is a common measure of disease activity in relapsing-remitting multiple sclerosis (MS). The objective of this study was to test the content validity of an operational algorithm for detecting relapse in claims data. A claims-based relapse detection algorithm was tested by comparing its detection rate over a 1-year period with relapses identified based on medical chart review. According to the algorithm, MS patients in a US healthcare claims database who had either (1) a primary claim for MS during hospitalization or (2) a corticosteroid claim following a MS-related outpatient visit were designated as having a relapse. Patient charts were examined for explicit indication of relapse or care suggestive of relapse. Positive and negative predictive values were calculated. Medical charts were reviewed for 300 MS patients, half of whom had a relapse according to the algorithm. The claims-based criteria correctly classified 67.3% of patients with relapses (positive predictive value) and 70.0% of patients without relapses (negative predictive value; kappa 0.373: p < 0.001). Alternative algorithms did not improve on the predictive value of the operational algorithm. Limitations of the algorithm include lack of differentiation between relapsing-remitting MS and other types, and that it does not incorporate measures of function and disability. The claims-based algorithm appeared to successfully detect moderate-to-severe MS relapse. This validated definition can be applied to future claims-based MS studies.

This study describes the availability and characteristics of databases in Asian-Pacific countries and assesses the feasibility of a distributed network approach in the region. A web-based survey was conducted among investigators using healthcare databases in the Asia-Pacific countries. Potential survey participants were identified through the Asian Pharmacoepidemiology Network. Investigators from a total of 11 databases participated in the survey. Database sources included four nationwide claims databases from Japan, South Korea, and Taiwan; two nationwide electronic health records from Hong Kong and Singapore; a regional electronic health record from western China; two electronic health records from Thailand; and cancer and stroke registries from Taiwan. We identified 11 databases with capabilities for distributed network approaches. Many country-specific coding systems and terminologies have been already converted to international coding systems. The harmonization of health expenditure data is a major obstacle for future investigations attempting to evaluate issues related to medical costs.

To review the evidence supporting the validity of billing, procedural, or diagnosis code, or pharmacy claim-based algorithms used to identify patients with rheumatoid arthritis (RA) in administrative and claim databases. We searched the MEDLINE database from 1991 to September 2012 using controlled vocabulary and key terms related to RA and reference lists of included studies were searched. Two investigators independently assessed the full text of studies against pre-determined inclusion criteria and extracted the data. Data collected included participant and algorithm characteristics. Nine studies reported validation of computer algorithms based on International Classification of Diseases (ICD) codes with or without free-text, medication use, laboratory data and the need for a diagnosis by a rheumatologist. These studies yielded positive predictive values (PPV) ranging from 34 to 97% to identify patients with RA. Higher PPVs were obtained with the use of at least two ICD and/or procedure codes (ICD-9 code 714 and others), the requirement of a prescription of a medication used to treat RA, or requirement of participation of a rheumatologist in patient care. For example, the PPV increased from 66 to 97% when the use of disease-modifying antirheumatic drugs and the presence of a positive rheumatoid factor were required. There have been substantial efforts to propose and validate algorithms to identify patients with RA in automated databases. Algorithms that include more than one code and incorporate medications or laboratory data and/or required a diagnosis by a rheumatologist may increase the PPV. Copyright © 2013 Elsevier Ltd.

To identify and assess diagnosis, procedure and pharmacy dispensing codes used to identify stillbirths and spontaneous abortion in administrative and claims databases from the United States or Canada. We searched the MEDLINE database from 1991 to September 2012 using controlled vocabulary and key terms related to stillbirth or spontaneous abortion. We also searched the reference lists of included studies. Two investigators independently assessed the full text of studies against pre-determined inclusion criteria. Two reviewers independently extracted data regarding participant and algorithm characteristics and assessed each study's methodological rigor using a pre-defined approach. Ten publications addressing stillbirth and four addressing spontaneous abortion met our inclusion criteria. The International Classification of Diseases, Ninth Revision (ICD-9) codes most commonly used in algorithms for stillbirth were those for intrauterine death (656.4) and stillborn outcomes of delivery (V27.1, V27.3-V27.4, and V27.6-V27.7). Papers identifying spontaneous abortion used codes for missed abortion and spontaneous abortion: 632, 634.x, as well as V27.0-V27.7. Only two studies identifying stillbirth reported validation of algorithms. The overall positive predictive value of the algorithms was high (99%-100%), and one study reported an algorithm with 86% sensitivity. However, the predictive value of individual codes was not assessed and study populations were limited to specific geographic areas. Additional validation studies with a nationally representative sample are needed to confirm the optimal algorithm to identify stillbirths or spontaneous abortion in administrative and claims databases.'

To estimate healthcare service utilisation costs of patients with rheumatoid arthritis in France and to estimate the fraction of these costs attributable to RA. The "Échantillon généraliste des bénéficiaires" (EGB) is a 1/97 random sample of the main national claims database covering the French population. A cohort of patients with rheumatoid arthritis was constituted of all adults benefiting from full coverage for rheumatoid arthritis (ICD-10 M05-06) on 1st january 2009. A control group matched for age and gender was identified. Health expenditures were assessed from the payer's perspective for the year 2010. The annual per capita reimbursed total health expenditure was €6,404 in 2010, an amount around two times higher than in the control group €3,095 (P<0.0001). The main contributors to this extra cost were outpatient care (+€2,407; 72.7%), including medication (+€1,686; 50.0%), and inpatient care (+€903; 27.3%). Patients treated by biological agents generated an age-adjusted per capita annual expenditure about three times higher than untreated patients (€15,757 versus €4,640). Only half of medical expenditure by patients with rheumatoid arthritis is attributable to their disease and use of biological agents has become a major driver of cost.

Tribulus terrestris (TT) is a dicotyledonous herbal plant of the Zygophyllaceae family. In ancient medicine, extracts of the aerial parts and fruits have been used for its diuretic, tonic, and aphrodisiac properties. Today, TT is widely used by athletes and bodybuilders based on the belief, fueled by claims in marketing information, that it can enhance testosterone concentrations. To assess TT's effect on testosterone levels in human and animals, an electronic literature search out using seven databases and the patent database up to August 2013 was carried out. Randomized control trials, which included healthy human subjects ingesting TT as sole or combined supplement, along with animal studies with TT as a sole treatment across a number of species were included. Eleven studies met the inclusion criteria, including one patent application. The results showed that trials varied in duration, dosage and supplementation with TT as sole or combined treatment, rendering meta-analysis impossible. A limited number of animal studies displayed a significant increase in serum testosterone levels after TT administration, but this effect was only noted in humans when TT was part of a combined supplement administration. Literature available for the effectiveness of TT on enhancing testosterone concentrations is limited. Evidence to date suggests that TT is ineffective for increasing testosterone levels in humans, thus marketing claims are unsubstantiated. The nitric oxide release effect of TT may offer a plausible explanation for the observed physiological responses to TT supplementation, independent of the testosterone level.

To assess whether type of long-term care service is a risk factor of the incidence of pressure ulcers among older adults with dementia who are receiving long-term care insurance (LTCI). Data from LTCI beneficiaries (benefit level 1 or 2) with dementia, aged 60 and older (n = 7841), in the Korean Elderly Cohort data set from 2008 to 2013 were used. Type of long-term care service was categorized into home or institutional care using the LTCI Claims Database. The National Health Insurance Claims Database was used to identify the incidence of pressure ulcers as the outcome variable in a survival analysis using the time-dependent Cox proportional hazard model. Of the 7841 participants, 98 (1.2%) exhibited pressure ulcers. Compared with beneficiaries receiving home care, those receiving institutional care had a higher adjusted hazard ratio for pressure ulcers (hazard ratio 6.48, 95% confidence interval 3.48-10.86). These associations were particularly strong among beneficiaries without pressure ulcers during the mandatory assessment for benefit eligibility and who were partially ambulatory. Beneficiaries receiving institutional care were more likely to have pressure ulcers than were those receiving home care. The government must monitor the quality of institutional long-term care services and encourage service providers to improve such care.

Indexing of Patents of Pharmaceutical Composition in Online Databases
NASA Astrophysics Data System (ADS)
Online searching of patents of pharmaceutical composition is generally considered to be very difficult. It is due to the fact that the patent databases include extensive technical information as well as legal information so that they are not likely to have index proper to the pharmaceutical composition or even if they have such index, the scope and coverage of indexing is ambiguous. This paper discusses how patents of pharmaceutical composition are indexed in online databases such as WPl, CA, CLAIMS, USP and PATOLIS. Online searching of patents of pharmaceutical composition are also discussed in some detail.

To compare the healthcare costs of pre-dialysis chronic kidney disease (CKD) patients cared for in a nephrology clinic setting versus other care settings. An analysis of health claims between 01/2002 and 09/2007 from the Ingenix Impact Database was conducted. Inclusion criteria were ≥ 18 years of age, ≥ 1 ICD-9 claim for CKD, and ≥ 1 estimated glomerular filtration rate (eGFR) value of < 60 mL/min/1.73 m(2). Patients were classified in the nephrology care cohort if they were treated in a nephrology clinic setting at least once during the study period. Univariate and multivariate analyses were conducted to compare average annualized healthcare costs of patients in nephrology care versus other care settings. Among the 20,135 patients identified for analysis, 1,547 patients were cared for in a nephrology clinic setting. Nephrology care was associated with lower healthcare costs with an unadjusted cost savings of $3,049 ($11,303 vs. $14,352, p = 0.0014) and a cost ratio of 0.8:1 relative to other care settings. After adjusting for covariates, nephrology care remained associated with lower costs (adjusted cost savings: $2,742, p = 0.006). Key limitations included potential inaccuracies of claims data, the lack of control for patients' ethnicity in the calculation of eGFR values, and the presence of potential biases due to the observational design of the study. The current study demonstrated that pre-dialysis CKD patients treated in nephrology clinics were associated with significantly lower healthcare costs compared with patients treated in other healthcare settings.

Ontological interpretation of biomedical database content.

Biological databases store data about laboratory experiments, together with semantic annotations, in order to support data aggregation and retrieval. The exact meaning of such annotations in the context of a database record is often ambiguous. We address this problem by grounding implicit and explicit database content in a formal-ontological framework. By using a typical extract from the databases UniProt and Ensembl, annotated with content from GO, PR, ChEBI and NCBI Taxonomy, we created four ontological models (in OWL), which generate explicit, distinct interpretations under the BioTopLite2 (BTL2) upper-level ontology. The first three models interpret database entries as individuals (IND), defined classes (SUBC), and classes with dispositions (DISP), respectively; the fourth model (HYBR) is a combination of SUBC and DISP. For the evaluation of these four models, we consider (i) database content retrieval, using ontologies as query vocabulary; (ii) information completeness; and, (iii) DL complexity and decidability. The models were tested under these criteria against four competency questions (CQs). IND does not raise any ontological claim, besides asserting the existence of sample individuals and relations among them. Modelling patterns have to be created for each type of annotation referent. SUBC is interpreted regarding maximally fine-grained defined subclasses under the classes referred to by the data. DISP attempts to extract truly ontological statements from the database records, claiming the existence of dispositions. HYBR is a hybrid of SUBC and DISP and is more parsimonious regarding expressiveness and query answering complexity. For each of the four models, the four CQs were submitted as DL queries. This shows the ability to retrieve individuals with IND, and classes in SUBC and HYBR. DISP does not retrieve anything because the axioms with disposition are embedded in General Class Inclusion (GCI) statements. Ambiguity of biological database content is addressed by a method that identifies implicit knowledge behind semantic annotations in biological databases and grounds it in an expressive upper-level ontology. The result is a seamless representation of database structure, content and annotations as OWL models.

The authors analyzed all medical malpractice claims from 2000 to 2008 using cases from the national database of the judicial system of Taiwan. The objective was to describe the factors associated with malpractice claims in Taiwan, a non-Western country that does not have a common law heritage. Emergency physicians (EPs) were the most likely to be sued and made the highest median payments. Most lawsuits involved death or permanent injury. Eighty-two percent of the cases were settled in the physician's favor. © 2012 by the Society for Academic Emergency Medicine.

To estimate direct and indirect costs in patients with a diagnosis of cluster headache in the US. Adult patients (18-64 years of age) enrolled in the Marketscan Commercial and Medicare Databases with ≥2 non-diagnostic outpatient (≥30 days apart between the two outpatient claims) or ≥1 inpatient diagnoses of cluster headache (ICD-9-CM code 339.00, 339.01, or 339.02) between January 1, 2009 and June 30, 2014, were included in the analyses. Patients had ≥6 months of continuous enrollment with medical and pharmacy coverage before and after the index date (first cluster headache diagnosis). Three outcomes were evaluated: (1) healthcare resource utilization, (2) direct healthcare costs, and (3) indirect costs associated with work days lost due to absenteeism and short-term disability. Direct costs included costs of all-cause and cluster headache-related outpatient, inpatient hospitalization, surgery, and pharmacy claims. Indirect costs were based on an average daily wage, which was estimated from the 2014 US Bureau of Labor Statistics and inflated to 2015 dollars. There were 9,328 patients with cluster headache claims included in the analysis. Cluster headache-related total direct costs (mean [standard deviation]) were $3,132 [$13,396] per patient per year (PPPY), accounting for 17.8% of the all-cause total direct cost. Cluster headache-related inpatient hospitalizations ($1,604) and pharmacy ($809) together ($2,413) contributed over 75% of the cluster headache-related direct healthcare cost. There were three sub-groups of patients with claims associated with indirect costs that included absenteeism, short-term disability, and absenteeism + short-term disability. Indirect costs PPPY were $4,928 [$4,860] for absenteeism, $803 [$2,621] for short-term disability, and $3,374 [$3,198] for absenteeism + disability. Patients with cluster headache have high healthcare costs that are associated with inpatient admissions and pharmacy fulfillments, and high indirect costs associated with absenteeism and short-term disability.

The public gets most of its information about genetic research from the media. It has been suggested that media representations may involve exaggeration, called "genohype." To examine the accuracy and nature of media coverage of genetic research, we reviewed the reporting of single-gene discoveries and associated technologies in major daily newspapers in Canada, the United States, Great Britain and Australia. We used neutral search terms to identify articles about gene discoveries and associated technologies hosted on the Dow Jones Interactive and Canadian NewsDisk databases from January 1995 to June 2001. We compared the contents, claims and conclusions of the scientific journal article with those of the associated newspaper article. Coders subjectively assigned the newspaper articles to 1 of 3 categories: moderately to highly exaggerated claims, slightly exaggerated claims or no exaggerated claims. We used classification tree software to identify the variables that contributed to the assignment of each newspaper article to 1 of the 3 categories: attention structure (positioning in the newspaper and length of the article), authorship, research topic, source of information other than the scientific paper, type and likelihood of risks and benefits, discussion of controversy, valuation tone (positive or negative), framing (e.g., description of research, celebration of progress, report of economic prospects or ethical perspective), technical accuracy (either omissions or errors that changed the description of the methods or interpretation of the results) and use of metaphors. We examined 627 newspaper articles reporting on 111 papers published in 24 scientific and medical journals. Only 11% of the newspaper articles were categorized as having moderately to highly exaggerated claims; the majority were categorized as having no claims (63%) or slightly exaggerated claims (26%). The classification analysis ranked the reporting of risks as the most important variable in determining the categorization of newspaper articles. Only 15% of the newspaper articles and 5% of the scientific journal articles discussed costs or risks, whereas 97% of the newspaper articles and 98% of the scientific journal articles discussed the likelihood of benefits of the research. Our data suggest that the majority of newspaper articles accurately convey the results of and reflect the claims made in scientific journal articles. Our study also highlights an overemphasis on benefits and under-representation of risks in both scientific and newspaper articles. The cause and nature of this trend is uncertain.

Risk-adjusted operative mortality is the most important quality metric in cardiac surgery for determining The Society of Thoracic Surgeons (STS) Composite Score for star ratings. Accurate 30-day status is required to determine STS operative mortality. The goal of this study was to determine the effect of unknown or missing 30-day status on risk-adjusted operative mortality in a regional STS Adult Cardiac Surgery Database cooperative and demonstrate the ability to correct these deficiencies by matching with an administrative database. STS Adult Cardiac Surgery Database data were submitted by 27 hospitals from five hospital systems to the Texas Quality Initiative (TQI), a regional quality collaborative. TQI data were matched with a regional hospital claims database to resolve unknown 30-day status. The risk-adjusted operative mortality observed-to-expected (O/E) ratio was determined before and after matching to determine the effect of unknown status on the operative mortality O/E. TQI found an excessive (22%) unknown 30-day status for STS isolated coronary artery bypass grafting cases. Matching the TQI data to the administrative claims database reduced the unknowns to 7%. The STS process of imputing unknown 30-day status as alive underestimates the true operative mortality O/E (1.27 before vs 1.30 after match), while excluding unknowns overestimates the operative mortality O/E (1.57 before vs 1.37 after match) for isolated coronary artery bypass grafting. The current STS algorithm of imputing unknown 30-day status as alive and a strategy of excluding cases with unknown 30-day status both result in erroneous calculation of operative mortality and operative mortality O/E. However, external validation by matching with an administrative database can improve the accuracy of clinical databases such as the STS Adult Cardiac Surgery Database.

The Centers for Disease Control and Prevention estimates that 28.9 million adults had diabetes in 2012 in the US, though many patients are undiagnosed or not managing their condition. This study provides US national and state estimates of insured adults with type 2 diabetes who are diagnosed, receiving exams and medication, managing glycemic levels, with diabetes complications, and their health expenditures. Such information can be used for benchmarking and to identify gaps in diabetes detection and management. The study combines analysis of survey data with medical claims analysis for the commercially insured, Medicare, and Medicaid populations to estimate the number of adults with diagnosed type 2 diabetes and undiagnosed diabetes by insurance type, age, and sex. Medical claims analysis used the 2012 de-identified Normative Health Information database covering a nationally representative commercially insured population, the 2011 Medicare 5% Sample, and the 2008 Medicaid Mini-Max. Among insured adults in 2012, approximately 16.9 million had diagnosed type 2 diabetes, 1.45 million had diagnosed type 1 diabetes, and 6.9 million had undiagnosed diabetes. Of those with diagnosed type 2, approximately 13.0 million (77%) received diabetes medication-ranging from 70% in New Jersey to 82% in Utah. Suboptimal percentages had claims indicating recommended exams were performed. Of those receiving diabetes medication, 43% (5.6 million) had medical claims indicating poorly controlled diabetes-ranging from 29% with poor control in Minnesota and Iowa to 53% in Texas. Poor control was correlated with higher prevalence of neurological complications (+14%), renal complications (+14%), and peripheral vascular disease (+11%). Patients with poor control averaged $4,860 higher average annual health care expenditures-ranging from $6,680 for commercially insured patients to $4,360 for Medicaid and $3,430 for Medicare patients. This study highlights the large number of insured adults with undiagnosed type 2 diabetes by insurance type and state. Furthermore, this study sheds light on other gaps in diabetes care quality among patients with diagnosed diabetes and corresponding poorly controlled diabetes. These findings underscore the need for improvements in data collection and diabetes screening and management, along with policies that support these improvements.

In 2006, Fairbanks, AK, reported its first cases of fatal anaphylaxis as a result of Hymenoptera stings concurrent with an increase in insect reactions observed throughout the state. This study was designed to determine whether Alaska medical visits for insect reactions have increased. We conducted a retrospective review of three independent patient databases in Alaska to identify trends of patients seeking medical care for adverse reactions after insect-related events. For each database, an insect reaction was defined as a claim for the International Classification of Diseases, Ninth Edition (ICD-9), codes E9053, E906.4, and 989.5. Increases in insect reactions in each region were compared with temperature changes in the same region. Each database revealed a statistically significant trend in patients seeking care for insect reactions. Fairbanks Memorial Hospital Emergency Department reported a fourfold increase in patients in 2006 compared with previous years (1992-2005). The Allergy, Asthma, and Immunology Center of Alaska reported a threefold increase in patients from 1999 to 2002 to 2003 to 2007. A retrospective review of the Alaska Medicaid database from 1999 to 2006 showed increases in medical claims for insect reactions among all regions, with the largest percentage of increases occurring in the most northern areas. Increases in insect reactions in Alaska have occurred after increases in annual and winter temperatures, and these findings may be causally related.

There are no estimates of the nationwide incidence of motor neuron disease (MND) in France. We used the French health insurance information system to identify incident MND cases (2012-2014), and compared incidence figures to those from three external sources. We identified incident MND cases (2012-2014) based on three data sources (riluzole claims, hospitalisation records, long-term chronic disease benefits), and computed MND incidence by age, gender, and geographic region. We used French mortality statistics, Limousin ALS registry data, and previous European studies based on administrative databases to perform external comparisons. We identified 6553 MND incident cases. After standardisation to the United States 2010 population, the age/gender-standardised incidence was 2.72/100,000 person-years (males, 3.37; females, 2.17; male:female ratio = 1.53, 95% CI1.46-1.61). There was no major spatial difference in MND distribution. Our data were in agreement with the French death database (standardised mortality ratio = 1.01, 95% CI = 0.96-1.06) and Limousin ALS registry (standardised incidence ratio = 0.92, 95% CI = 0.72-1.15). Incidence estimates were in the same range as those from previous studies. We report French nationwide incidence estimates of MND. Administrative databases including hospital discharge data and riluzole claims offer an interesting approach to identify large population-based samples of patients with MND for epidemiologic studies and surveillance.

In recent decades, the frequency of Medical Only (MO) and Lost Time (LT) workers' compensation claims has decreased, while average severity (medical and indemnity costs) has increased. The aim of this study was to compare claim frequency, mix, and severity (cost) over two periods using a claim cohort follow-up method. Sixty-two thousand five hundred thirty-three claims during two periods (1999 to 2002 and 2003 to 2006) were followed seven years postinjury. Descriptive analysis and significant testing methods were used to compare claim frequency and costs. The number of claims per $1 M of premium decreased 50.4% for MO claims and 35.6% for LT claims, consequently increasing the LT claim proportion. The average cost of LT claims did not increase. The severity increase is attributable to the proportional change in LT and MO claims. While the number of LT claims decreased, the inflation-adjusted average cost of LT claims did not increase.

We evaluated the effectiveness of warning letters published by the pharmaceutical regulatory agency in Japan on communication of drug safety and risk by quantitative analysis of the national health insurance claims database (NHICD). We then explored what factors may have affected risk communication. We measured the implementation rate of the hepatitis virus-monitoring test among methotrexate (MTX)-treated patients; a warning letter had been issued regarding the use of MTX, as it apparently activates the hepatitis virus. Data from the NHICD, which include 99·3% of Japanese residents, were used. A total of 4,933,481 patients with rheumatoid arthritis (RA) (January-June, 2010) were the focus of this study. The implementation rate of the hepatitis virus-monitoring test increased from 1·4% before to 1·8% after the warning letter announcement. Logistic regression analysis suggested that the installation of a drug information management room is one of the important factors affecting risk communication. Further analysis revealed that the hepatitis virus monitoring rates in hospitals without drug information management rooms increased from 2·3% to 4·1% due to the issue of the warning letter. The warning letter from the regulatory agency plays an important role in risk communication in hospitals without drug information management rooms. © 2015 John Wiley & Sons Ltd.

[Urological diseases most frequently involved in medical professional liability claims].
Vargas-Blasco, César; Gómez-Durán, Esperanza L; Arimany-Manso, Josep; Pera-Bajo, Francisco
2014-03-01
Clinical safety and medical professional liability are international major concerns, especially in surgical specialties such as urology. This article analyzes the claims filed at the Council of Medical Colleges of Catalonia between 1990 and 2012, exploring urology procedures. The review of the 173 cases identified in the database highlighted the importance of surgical procedures (74%). Higher frequencies related to scrotal-testicular pathology (34%), especially testicular torsion (7.5%) and vasectomy (19.6%), and prostate pathology (26 %), more specifically the surgical treatment of benign prostatic hyperplasia (17.9%). Although urology is not among the specialties with the higher frequency of claims, there are special areas of litigation in which it is advisable to implement improvements in clinical safety.

An orthopaedic malpractice claim alleges that the patient sustained a preventable iatrogenic injury. The analysis of a representative series of malpractice claims provides a unique view of alleged orthopaedic adverse events, revealing what can potentially go wrong across a spectrum of practice settings and anatomic locations. The goal of this study was to identify high-impact targets in order to institute measures to reduce claims through efforts focused on patient safety. The authors investigated 464 consecutive closed malpractice claims from the nation's largest insurer of medical liability. We analyzed the claims by anatomical site, type of care rendered, type of allegation, and payment. We calculated an "impact factor" for each claim type by dividing the percentage of total payments for each type by the percentage of total claims for that type. Our analysis revealed major concerns regarding patient safety within this series of malpractice claims. One-third of the claims alleged permanent disabling injuries, including amputations, brain damage, and major nerve damage. The highest impact allegations were failure to protect structures in the surgical field (41% of total payments to plaintiffs, 15% of all claims, impact factor of 2.7) and failure to prevent, diagnose, and/or treat complications of treatment (16% of total payments, 7% of all claims, impact factor of 2.3). Spine procedures had high impact (1.9), representing 28% of dollars paid and 15% of claims, with 45% of spine claims involving death or severe permanent injury. Failure of implant positioning was commonly alleged in hip and knee arthroplasty. In claims related to fracture care, the most common allegations were related to malunions, nonunions, dislocations, failure to protect structures in the surgical field, infection, and treatment complications. Total payment for the eighty-eight claims paid was $17,917,614 (U.S. dollars adjusted to 2009). Regarding clinical relevance, this analysis suggests risk areas for targeted efforts to improve patient safety and reduce malpractice claims.
Influencing factors leading to malpractice litigation in radical prostatectomy.
Colaco, Marc; Sandberg, Jason; Badlani, Gopal
2014-06-01
The litigious nature of the medical-legal environment is a major concern for American physicians with an estimated cost of $10 billion. In this study we identify the causes of litigation in cases of radical prostatectomy as well as the factors that contribute to verdicts or settlements resulting in indemnity payments. Publicly available verdict reports were recorded using the Westlaw® legal database. To identify pertinent cases we used the search terms "medical malpractice" and "prostate" or "prostatectomy" with dates ranging from 2000 to 2013. Cases were evaluated for alleged cause of malpractice, resulting injury, findings and indemnity payment (if any). The database search yielded 222 cases, with 25 being relevant to radical prostatectomy. Of these cases 24.0% were settled out of court and the remaining 76.0% went to trial. Of those cases that went to trial 20.8% saw patients awarded damages. There was no significant difference in awards between verdict and settlement. Overall 36.0% of patients claimed that they did not receive proper informed consent and 16.0% claimed that the surgery was not the proper standard of care. Thirteen of the cases claimed negligence in the performance of the surgery with the bulk of these claims being the result of rectal perforation. The main issues that arise in radical prostatectomy malpractice litigation are those of informed consent and clinical performance. Comprehensive preoperative counseling, when combined with proper surgical technique, may minimize the impact of litigation.

Tracking and trending rates of injuries and illnesses classified as musculoskeletal disorders caused by ergonomic risk factors such as overexertion and repetitive motion (MSDs) and slips, trips, or falls (STFs) in different industry sectors is of high interest to many researchers. Unfortunately, identifying the cause of injuries and illnesses in large datasets such as workers' compensation systems often requires reading and coding the free form accident text narrative for potentially millions of records. To alleviate the need for manual coding, this paper describes and evaluates a computer auto-coding algorithm that demonstrated the ability to code millions of claims quickly and accurately by learning from a set of previously manually coded claims. The auto-coding program was able to code claims as a musculoskeletal disorders, STF or other with approximately 90% accuracy. The program developed and discussed in this paper provides an accurate and efficient method for identifying the causation of workers' compensation claims as a STF or MSD in a large database based on the unstructured text narrative and resulting injury diagnoses. The program coded thousands of claims in minutes. The method described in this paper can be used by researchers and practitioners to relieve the manual burden of reading and identifying the causation of claims as a STF or MSD. Furthermore, the method can be easily generalized to code/classify other unstructured text narratives. Published by Elsevier Ltd.

This retrospective analysis assessed the capability of active and passive safety surveillance systems to track product-specific safety events in the USA for branded and generic enoxaparin, a complex injectable subject to immune-related and other adverse events (AEs). Analysis of heparin-induced thrombocytopenia (HIT) incidence was performed on benefit claims for commercial and Medicare supplemental-insured individuals newly treated with enoxaparin under pharmacy benefit (1 January 2009 - 30 June 2012). Additionally, spontaneous reports from the FDA AE Reporting System were reviewed to identify incidence and attribution of enoxaparin-related reports to specific manufacturers. Specific, dispensed products were identifiable from National Drug Codes only in pharmacy-benefit databases, permitting sensitive comparison of HIT incidence in nearly a third of patients treated with brand or generic enoxaparin. After originator medicine's loss of exclusivity, only 5% of spontaneous reports were processed by generic manufacturers; reports attributable to specific generics were approximately ninefold lower than expected based on market share. Claims data were useful for active surveillance of enoxaparin generics dispensed under pharmacy benefits but not for products administered under medical benefits. These findings suggest that the current spontaneous reporting system will not distinguish product-specific safety signals for products distributed by multiple manufacturers, including biosimilars.

Ghana introduced the National Health Insurance Scheme (NHIS) in 2003 to provide financial access to health care for all residents. This article analyzed claims reimbursement data of the NHIS to assess the value of the benefit package to the insured and responsiveness of the service to the financial needs of health services providers. Medical claims data reported between January 1, 2010, and December 31, 2014, were retrieved from the database of Ashiedu Keteke District Office of the National Health Insurance Authority. The incurred claims ratio, promptness of claims settlements, and claims adjustment rate were analyzed over the 5-year period. In all, 644,663 medical claims with a cost of Ghana cedi (GHS) 11.8 million (US $3.1 million) were reported over the study period. The ratio of claims cost to contributions paid increased from 4.3 to 7.2 over the 2011-2013 period, and dropped to 5.0 in 2014. The proportion of claims settled beyond 90 days also increased from 26% to 100% between 2011 and 2014. Generally, the amount of claims adjusted was low; however, it increased consistently from 1% to about 4% over the 2011-2014 period. The reasons for claims adjustments included provision of services to ineligible members, overbilling of services, and misapplication of diagnosis related groups. There is increased value of the NHIS benefit package to subscribers; however, the scheme's responsiveness to the financial needs of health services providers is low. This calls for a review of the NHIS policy to improve financial viability and service quality. Copyright © 2016 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Medical malpractice claims in relation to colorectal malignancy in the national health service.
Markides, G A; Newman, C M
2014-01-01
Under the current increased financial constraints affecting the National Health Service (NHS), clinical negligence claims and associated compensations are constantly rising. Our aim was to identify the magnitude, trends and causes of malpractice claims in relation to a common pathology such as colorectal malignancy in the NHS. Data requests were submitted to the NHS Litigation Authority (NHSLA) and to the Medical Defence Union (MDU) and Medical Protection Society (MPS). Data were reviewed, categorized clinically and analysed in terms of causes and costs behind claims. Data from the MPS and MDU were unavailable. In all, 169 claims were identified from the NHSLA database between 2003 and 2012; 123 (73%) cases had been closed, 80 (65%) of which were successful. An increasing overall claim frequency and success rate were found over the last few years. Total litigation expenses were £8.6 million, with 39% paid out as legal expenses. The commonest cause of complaint in successful claims was in relation to diagnostic delays or failures (58%, £5.1 million), with a delay or failure by the clinician to take action in response to an abnormal investigation result being a major factor. The occurrence of peri-operative complications (20%, £1.6 million) was the second commonest cause. Average frequency and success rates of malpractice claims in secondary care in the NHS are rising, leading to significant overall payouts. The failure or delay in diagnosing colorectal malignancy or its postoperative complications is a common cause behind malpractice claims. Improvement in these areas could enhance patient care and reduce future claims. Colorectal Disease © 2013 The Association of Coloproctology of Great Britain and Ireland.
Musculoskeletal disorders and associated healthcare costs among family members of injured workers.
Asfaw, Abay; Pana-Cryan, Regina; Bushnell, Tim; Sauter, Steven
2015-11-01
Research has infrequently looked beyond the injured worker when gauging the burden of occupational injury. We explored the relationship between occupational injury and musculoskeletal disorders (MSDs) among family members of injured workers. We used 2005 and 2006 Truven Health Analytics databases, which contain information on workers' compensation and family healthcare claims. We used descriptive analyses, and negative binomial and two-part models. Family members of severely injured workers had a 15% increase in the total number of MSD outpatient claims and a 34% increase in the mean cost of MSD claims compared to family members of non-severely injured workers within 3 months after injury. Extrapolating cost results to the national level implies that severe occupational injury would be associated with between $29 and $33 million additional cost of family member outpatient MSD claims. Occupational injury can impose a formerly unrecognized health burden on family members of injured workers. Published 2015.

The weights-of-evidence analysis, a quantitative mineral resource mapping tool, is used to delineate favorable areas for epithermal gold deposits and to predict future exploration activity of the mineral industry for similar deposits in a four-county area (222 x 277 km), including the Okanogan and Colville National Forests of northeastern Washington. Modeling is applied in six steps: (1) building a spatial digital database, (2) extracting predictive evidence for a particular deposit, based on an exploration model, (3) calculating relative weights for each predictive map, (4) combining the geologic evidence maps to predict the location of undiscovered mineral resources and (5) measuring the intensity of recent exploration activity by use of mining claims on federal lands, and (6) combining mineral resource and exploration activity into an assessment model of future mining activity. The analysis is accomplished on a personal computer using ArcView GIS platform with Spatial Analyst and Weights-of-Evidence software. In accord with the descriptive model for epithermal gold deposits, digital geologic evidential themes assembled include lithologic map units, thrust faults, normal faults, and igneous dikes. Similarly, geochemical evidential themes include placer gold deposits and gold and silver analyses from stream sediment (silt) samples from National Forest lands. Fifty mines, prospects, or occurrences of epithermal gold deposits, the training set, define the appropriate a really-associated terrane. The areal (or spatial) correlation of each evidential theme with the training set yield predictor theme maps for lithology, placer sites and normal faults. The weights-of-evidence analysis disqualified the thrust fault, dike, and gold and silver silt analyses evidential themes because they lacked spatial correlation with the training set. The decision to accept or reject evidential themes as predictors is assisted by considering probabilistic data consisting of weights and contrast values calculated for themes according to areal correlation with the training sites. Predictor themes having acceptable weights and contrast values are combined into a preliminary model to predict the locations of undiscovered epithermal gold deposits. This model facilitates ranking of tracts as non-permissive, permissive or favorable categories based on exclusionary, passive, and active criteria through evaluation of probabilistic data provided by interaction of predictor themes. The method is very similar to the visual inspection method of drawing conclusions from anomalies on a manually overlain system of maps. This method serves as a model for future mineral assessment procedures because of its objective nature. To develop a model to predict future exploration activity, the locations of lode mining claims were summarized for 1980, 1985, 1990, and 1996. Land parcels containing historic claims were identified either as those with mining claims present in 1980 or valid claims present in 1985. Current claim parcels were identified as those containing valid lode claims in either 1990 or 1996. A consistent parcel contains both historic and current claims. The epithermal gold and mining claim activity models were combined into an assessment (or mineral resource-activity) model to assist in land use decisions by providing a prediction of mineral exploration activity on federal land in the next decade. Ranks in the assessment model are: (1) no activity, (2) low activity, (3) low to moderate activity, (4) moderate activity and (5) high activity.

Tofacitinib is an oral Janus kinase inhibitor indicated for the treatment of rheumatoid arthritis (RA). Tofacitinib can be administered as a monotherapy or in combination with conventional synthetic disease-modifying antirheumatic drugs (DMARDs). This study describes RA patients' characteristics, treatment patterns, and costs for those initiating tofacitinib treatment as monotherapy or combination therapy, using US claims data from clinical practice. A retrospective cohort analysis of patients aged ≥18 years with RA (International Classification of Diseases, Ninth Revision code 714.xx) and with ≥1 tofacitinib claim in the Truven Marketscan (TM) or the Optum Clinformatics (OC) database. Index was defined as the first tofacitinib fill date (November 2012-June 2014). Patients were continuously enrolled for ≥12 months before and after index. Adherence was assessed using the proportion of days covered (PDC) and medication possession ratio (MPR). Persistence was evaluated using a 1.5× days' supply gap or switch. All-cause and RA-related costs in the 12-month pre- and post-index periods were evaluated. Unadjusted and adjusted analyses were conducted on data on treatment patterns and costs stratified by monotherapy status. A total of 337 (TM) and 118 (OC) tofacitinib patients met the selection criteria; 52.2% (TM) and 50.8% (OC) received monotherapy and 83.7% (TM) and 76.3% (OC) had pre-index biologic DMARD experience. Twelve-month mean PDC values were 0.56 (TM) and 0.53 (OC), and 12-month mean MPR was 0.84 (TM) and 0.80 (OC), with persistence of 140.0 (TM) and 124.6 (OC) days. Between 12-month pre- and post-index periods, mean (SD) 12-month RA-related medical costs decreased by $5784 ($31,832) in TM and $6103 ($25,897) in OC (both, P < 0.05), whereas total costs increased by $3996 ($30,397) in TM (P < 0.05) and $1390 ($26,603) in OC. There were no significant differences in adherence, persistence, or all-cause/RA-related costs between monotherapy and combination therapy in unadjusted/adjusted analyses. This analysis adds to the existing tofacitinib knowledge base and will enable informed clinical and policy decision making based on valuable datasets independent of randomized controlled trials.

2012-07-01
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, and patients with AF are at an increased risk for stroke. Thromboprophylaxis with vitamin K antagonists reduces the annual incidence of stroke by approximately 60%, but appropriate thromboprophylaxis is prescribed for only approximately 50% of eligible patients. Health plans may help to improve quality of care for patients with AF by analyzing claims data for care improvement opportunities. To analyze pharmacy and medical claims data from a large integrated commercial database to determine the risk for stroke and the appropriateness of anticoagulant use based on guideline recommendations for patients with AF. This descriptive, retrospective claims data analysis used the Anticoagulant Quality Improvement Analyzer software, which was designed to analyze health plan data. The data for this study were obtained from a 10% randomly selected sample from the PharMetrics Integrated Database. This 10% sample resulted in almost 26,000 patients with AF who met the inclusion criteria for this study. Patients with a new or existing diagnosis of AF between July 2008 and June 2010 who were aged ≥18 years were included in this analysis. The follow-up period was 1 year. Demographics, stroke risk level (CHADS2 and CHA2DS2-VASc scores), anticoagulant use, and inpatient stroke hospitalizations were analyzed through the analyzer software. Of the 25,710 patients with AF (CHADS2 score 0-6) who were eligible to be included in this study, 9093 (35%) received vitamin K antagonists and 16,617 (65%) did not receive any anticoagulant. Of the patients at high risk for stroke, as predicted by CHADS2, 39% received an anticoagulant medication. The rates of patients receiving anticoagulant medication varied by age-group-16% of patients aged <65 years, 22% of those aged 65 to 74 years, and 61% of elderly ≥75 years. Among patients hospitalized for stroke, only 28% were treated with an anticoagulant agent in the outpatient setting before admission. Our findings support the current literature, indicating that many patients with AF are not receiving appropriate thromboprophylaxis to counter their risk for stroke. Increased use of appropriate anticoagulation, particularly in high-risk patients, has the potential to reduce the incidence of stroke along with associated fatalities and morbidities.

The Clinical and Economic Burden of Hyperkalemia on Medicare and Commercial Payers.
Fitch, Kathryn; Woolley, J Michael; Engel, Tyler; Blumen, Helen
2017-06-01
Hyperkalemia (serum potassium >5.0 mEq/L) may be caused by reduced kidney function and drugs affecting the renin-angiotensin-aldosterone system and is often present in patients with chronic kidney disease (CKD). To quantify the burden of hyperkalemia in US Medicare fee-for-service and commercially insured populations using real-world claims data, focusing on prevalence, comorbidities, mortality, medical utilization, and cost. A descriptive, retrospective claims data analysis was performed on patients with hyperkalemia using the 2014 Medicare 5% sample and the 2014 Truven Health Analytics MarketScan Commercial Claims and Encounter databases. The starting study samples required patient insurance eligibility during ≥1 months in 2014. The identification of hyperkalemia and other comorbidities required having ≥1 qualifying claims in 2014 with an appropriate International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code in any position. To address the differences between patients with and without hyperkalemia, CKD subsamples were analyzed separately. Mortality rates were calculated in the Medicare sample population only. The claims were grouped into major service categories; the allowed costs reflected all costs incurred by each cohort divided by the total number of member months for that cohort. The prevalence of hyperkalemia in the Medicare and commercially insured samples was 2.3% and 0.09%, respectively. Hyperkalemia was associated with multiple comorbidities, most notably CKD. The prevalence of CKD in the Medicare and the commercially insured members with hyperkalemia was 64.8% and 31.8%, respectively. After adjusting for CKD severity, the annual mortality rate for Medicare patients with CKD and hyperkalemia was 24.9% versus 10.4% in patients with CKD without hyperkalemia. The allowed costs in patients with CKD and hyperkalemia in the Medicare and commercially insured cohorts were more than twice those in patients with CKD without hyperkalemia. Inpatient care accounted for >50% of costs in patients with CKD and hyperkalemia. Hyperkalemia is associated with substantial clinical and economic burden among US commercially insured and Medicare populations.

In Japan, there have been approximately 50 000 deaths from gastric cancer annually for over 40 years with little variation. It has been reported that most gastric cancers in Japan are caused by Helicobacter pylori infection. H. pylori eradication therapy was approved for patients with chronic gastritis by the Japanese national health insurance scheme in February 2013 for patients with an endoscopic diagnosis of chronic gastritis is positive for H. pylori. We examined the effect on gastric cancer death rate 4 years after expansion of health insurance coverage. We conducted an epidemiological study and analyzed trends in prescription for H. pylori eradication therapy. We used the electronic medical claims database from Hokkaido, Japan to evaluate the impact of expansion of national health insurance coverage for H. pylori eradication therapy on deaths from gastric cancer. Data on deaths from gastric cancer were obtained from the Japanese Ministry of Health, Labour and Welfare and the Cancer Statistics in Japan (2015). Analysis of electronic claims records was performed using the National Database, mainly focusing on Hokkaido. Prescriptions for H. pylori eradication therapy and the number of patients treated for gastric cancer were also extracted from the Hokkaido database. Approximately 1.5 million prescriptions for H. pylori eradication therapy were written annually. Gastric cancer deaths fell each year: 48 427 in 2013, 47 903 in 2014, 46 659 in 2015, and 45 509 in 2016, showing a significant decrease after expansion of insurance coverage for H. pylori eradication therapy (P<.0001). Prescriptions for H. pylori eradication therapy increased markedly after approval of the gastritis indication by the national health insurance scheme and was associated with a significant decrease in gastric cancer deaths. © 2017 The Authors.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening diseases; however, it is hard to estimate their incidence due to the rarity of these diseases. We evaluated the incidence of SJS and TEN using a nationwide administrative database. We used a national medical insurance review system (Health Insurance Review and Assessment) database which contained the claim data of the entire nation from 2009 to 2013 to estimate the accurate incidence of SJS and TEN in Korea. The diagnostic codes of L511 (SJS) or L512 (TEN) from the International Classification of Diseases-10th revision were used to define the target study population. We also retrospectively followed up a 2011 SJS and TEN cohort for 24 months in order to assess the in-hospital mortality, related complications and total claims cost due to SJS and TEN. A total of 1,167 (938 SJS and 229 TEN) cases were newly diagnosed from 2010 to 2013. The age- and sex-standardized annual incidences estimated in this study were 3.96 to 5.03 in SJS and 0.94 to 1.45 in TEN per million. There was no significant change in annual incidence throughout the study periods. When analyzed by 10-year age groups, the annual incidence was the lowest in group 20-29 years and the highest in group 70 for both SJS and TEN. Based on the 2011 cohort analysis, the in-hospital mortality were 5.7 and 15.1% for SJS and TEN, respectively. The mortality increased with age, particularly, after 40 years of age. Among the complications related with SJS or TEN, ocular sequelae was the most common (43.1 and 43.4% of SJS and TEN patients, respectively) followed by urethral sequelae (5.7 and 9.4% of SJS and TEN patients, respectively). Overall, our data suggest that SJS, and TEN are infrequent but constantly arise throughout the years.

This study analyzed workers' compensation patients after surgical or nonoperative treatment of clavicle fractures to identify factors that influence the time for return to work and total health care reimbursement claims. We hypothesized that return to work for operative patients would be faster. The International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes and Current Procedural Terminology codes were used to retrospectively query the Workers' Compensation national database. The outcomes of interest were the number of days for return to full work after surgery and total reimbursement for health care-related claims. The primary independent variable was treatment modality. There were 169 claims for clavicle fractures within the database (surgical, n = 34; nonoperative, n = 135). The average health care claims reimbursed were $29,136 ± $26,998 for surgical management compared with $8366 ± $14,758 for nonoperative management (P < .001). We did not find a statistically significant difference between surgical (196 ± 287 days) and nonoperative (69 ± 94 days) treatment groups in their time to return to work (P = .06); however, there was high variability in both groups. Litigation was an independent predictor of prolonged return to work (P = .007) and higher health care costs (P = .003). Workers' compensation patients treated for clavicle fractures return to work at roughly the same time whether they are treated surgically or nonoperatively, with surgery being roughly 3 times more expensive. There was a substantial amount of variability in return to work timing by subjects in both groups. Litigation was a predictor of longer return to work timing and higher health care costs.

(1) To identify work-related fatal and non-fatal hospitalised injuries using multiple data sources, (2) to compare case-ascertainment from external data sources with accepted workers' compensation claims and (3) to investigate the characteristics of work-related fatal and hospitalised injuries not captured by workers' compensation. Work-related fatal injuries were ascertained from vital statistics, coroners and hospital discharge databases using payment and diagnosis codes and injury and work descriptions; and work-related (non-fatal) injuries were ascertained from the hospital discharge database using admission, diagnosis and payment codes. Injuries for British Columbia residents aged 15-64 years from 1991 to 2009 ascertained from the above external data sources were compared to accepted workers' compensation claims using per cent captured, validity analyses and logistic regression. The majority of work-related fatal injuries identified in the coroners data (83%) and the majority of work-related hospitalised injuries (95%) were captured as an accepted workers' compensation claim. A work-related coroner report was a positive predictor (88%), and the responsibility of payment field in the hospital discharge record a sensitive indicator (94%), for a workers' compensation claim. Injuries not captured by workers' compensation were associated with female gender, type of work (natural resources and other unspecified work) and injury diagnosis (eg, airway-related, dislocations and undetermined/unknown injury). Some work-related injuries captured by external data sources were not found in workers' compensation data in British Columbia. This may be the result of capturing injuries or workers that are ineligible for workers' compensation, or the result of injuries that go unreported to the compensation system. Hospital discharge records and coroner reports may provide opportunities to identify workers (or family members) with an unreported work-related injury and to provide them with information for submitting a workers' compensation claim.

Objectives (1) To identify work-related fatal and non-fatal hospitalised injuries using multiple data sources, (2) to compare case-ascertainment from external data sources with accepted workers’ compensation claims and (3) to investigate the characteristics of work-related fatal and hospitalised injuries not captured by workers’ compensation. Methods Work-related fatal injuries were ascertained from vital statistics, coroners and hospital discharge databases using payment and diagnosis codes and injury and work descriptions; and work-related (non-fatal) injuries were ascertained from the hospital discharge database using admission, diagnosis and payment codes. Injuries for British Columbia residents aged 15–64 years from 1991 to 2009 ascertained from the above external data sources were compared to accepted workers’ compensation claims using per cent captured, validity analyses and logistic regression. Results The majority of work-related fatal injuries identified in the coroners data (83%) and the majority of work-related hospitalised injuries (95%) were captured as an accepted workers’ compensation claim. A work-related coroner report was a positive predictor (88%), and the responsibility of payment field in the hospital discharge record a sensitive indicator (94%), for a workers’ compensation claim. Injuries not captured by workers’ compensation were associated with female gender, type of work (natural resources and other unspecified work) and injury diagnosis (eg, airway-related, dislocations and undetermined/unknown injury). Conclusions Some work-related injuries captured by external data sources were not found in workers’ compensation data in British Columbia. This may be the result of capturing injuries or workers that are ineligible for workers’ compensation, or the result of injuries that go unreported to the compensation system. Hospital discharge records and coroner reports may provide opportunities to identify workers (or family members) with an unreported work-related injury and to provide them with information for submitting a workers’ compensation claim.

The National Flood Insurance Program (NFIP) was established in 1968 to curtail unfettered development on US floodplains and spiraling taxpayer expenditures for disaster relief. Currently NFIP underwrites >5 million policies, providing >1.25 trillion in coverage, and taking in >3.5 billion in annual premiums. Cumulative flood-damage payouts to date exceed premiums collected by >$20 billion. Our group has obtained nationwide databases of NFIP flood-damage claims back to 1972, annual policies since 1994, and selective Federal Emergency Management Agency (FEMA) repetitive losses. Attributes include property, claims, and loss characteristics. Other attributes were stripped to maintain policyholder anonymity. At present, locations are to the nearest 0.1° lat/long, zip code, and by community. We combine NFIP data with GIS information from a variety of other sources. Over the past 44 years, 1,625,470 non-zero flood claims are documented. Numbers of claims and losses have increased over time, even with extreme events (Hurricanes Katrina and Sandy) excluded. Flood losses have occurred within 100-year floodplains (1% annual exceedance), in coastal hazard zones, and 25% of claims occur outside of mapped flood-hazard areas. We hypothesize that a many losses outside of FEMA's designated Special Flood Hazard Area (SFHA) correlate with (1) outdated map panels, (2) contrasting levels of enforcement and mitigation by state. Other distributed flood losses represent stormwater/drainage damage. Claim rates substantially exceed 1%, both in and outside the SFHA, and for "pre-FIRM" and "post-FIRM" structures. This suggests that ≥100-year floods are occurring more frequently than statutory frequencies suggest. For US homeowners, this suggests that flood insurance is a good deal in a variety of settings. The NFIP data analyzed here contrasts with our group's previous, largely model-driven research. Such empirical flood data exclude model assumptions, but add dizzying array of human and political factors into the resulting spatial and temporal patterns. Parsing out the hydrologic, climatic, social, and political factors influencing flood risk and resilience is crucial for sound management of NFIP and other programs. The US Congress will debate reauthorization and possible revision of NFIP in 2017.
Big Data in Organ Transplantation: Registries and Administrative Claims
Massie, Allan B.; Kucirka, Lauren; Segev, Dorry L.
2015-01-01
The field of organ transplantation benefits from large, comprehensive, transplant-specific national datasets available to researchers. In addition to the widely-used OPTN-based registries (the UNOS and SRTR datasets) and USRDS datasets, there are other publicly available national datasets, not specific to transplantation, which have historically been underutilized in the field of transplantation. Of particular interest are the Nationwide Inpatient Sample (NIS) and State Inpatient Databases (SID), produced by the Agency for Healthcare Research and Quality (AHRQ). The United States Renal Data System (USRDS) database provides extensive data relevant to studies of kidney transplantation. Linkage of publicly available datasets to external data sources such as private claims or pharmacy data provides further resources for registry-based research. Although these resources can transcend some limitations of OPTN-based registry data, they come with their own limitations, which must be understood to avoid biased inference. This review discusses different registry-based data sources available in the United States, as well as the proper design and conduct of registry-based research. PMID:25040084

The objective of this study was to examine the quantity and accuracy of dietary supplement (DS) information through magazines with high adolescent readership. Eight (8) magazines (3 teen and 5 adult with high teen readership) were selected. A content analysis for DS was conducted on advertisements and editorials (i.e., articles, advice columns, and bulletins). Noted claims/cautions regarding DS were evaluated for accuracy using Medlineplus.gov and Naturaldatabase.com. Claims for dietary supplements with three or more types of ingredients and those in advertisements were not evaluated. Advertisements were evaluated with respect to size, referenced research, testimonials, and Dietary Supplement Health and Education Act of 1994 (DSHEA) warning visibility. Eighty-eight (88) issues from eight magazines yielded 238 DS references. Fifty (50) issues from five magazines contained no DS reference. Among teen magazines, seven DS references were found: five in the editorials and two in advertisements. In adult magazines, 231 DS references were found: 139 in editorials and 92 in advertisements. Of the 88 claims evaluated, 15% were accurate, 23% were inconclusive, 3% were inaccurate, 5% were partially accurate, and 55% were unsubstantiated (i.e., not listed in reference databases). Of the 94 DS evaluated in advertisements, 43% were full page or more, 79% did not have a DSHEA warning visible, 46% referred to research, and 32% used testimonials. Teen magazines contain few references to DS, none accurate. Adult magazines that have a high teen readership contain a substantial amount of DS information with questionable accuracy, raising concerns that this information may increase the chances of inappropriate DS use by adolescents, thereby increasing the potential for unexpected effects or possible harm.
Drug Use among Seniors on Public Drug Programs in Canada, 2012.
Proulx, Jeff; Hunt, Jordan
2015-01-01
Seniors take more drugs than younger Canadians because, on average, they have a higher number of chronic conditions. Although taking multiple medications may be necessary to manage these conditions, it is important to consider the benefits and risks of each medication and the therapeutic goals of the patient. This article provides an in-depth look at the number and types of drugs used by seniors using drug claims data from the CIHI's National Prescription Drug Utilization Information System Database, representing approximately 70% of seniors in Canada. In 2012, almost two-thirds (65.9%) of seniors on public drug programs had claims for five or more drug classes, while 27.2% had claims for 10 or more, and 8.6% had claims for 15 or more. The most commonly used drug class was statins, used by nearly half (46.6%) of seniors. Nearly two-thirds (60.9%) of seniors living in long-term care (LTC) facilities had claims for 10 or more drug classes. Proton pump inhibitors were the most commonly used drug class among seniors living in LTC facilities (used by 37.0% of seniors in LTC facilities), while statins ranked seventh (29.8%).

Developing data-driven local solutions to address rising health care costs requires valid and reliable local data. Traditionally, local public health agencies have relied on birth, death, and specific disease registry data to guide health care planning, but these data sets provide neither health information across the lifespan nor information on local health care utilization patterns and costs. Insurance claims data collected by local hospitals for administrative purposes can be used to create valuable population health data sets. The Camden Coalition of Healthcare Providers partnered with the 3 health systems providing emergency and inpatient care within Camden, New Jersey, to create a local population all-payer hospital claims data set. The combined claims data provide unique insights into the health status, health care utilization patterns, and hospital costs on the population level. The cross-systems data set allows for a better understanding of the impact of high utilizers on a community-level health care system. This article presents an introduction to the methods used to develop Camden's hospital claims data set, as well as results showing the population health insights obtained from this unique data set.

To evaluate the effectiveness of direct pulp capping under general practice conditions. It was hypothesized that direct pulp capping is an effective procedure in the majority of cases and prevents the need for root canal treatment or extraction. Claims data were collected from the digital database of a major German national health insurance company. Only patients who had been insurance members for the entire 3 year period 2010 to 2012 were eligible. Kaplan-Meier survival analyses were conducted for all teeth with direct pulp capping. Success was defined as not undergoing root canal treatment. Survival was defined as not undergoing extraction. Differences between survival functions were tested with the log rank test. A total of 148 312 teeth were included. The overall success rate was 71.6% at 3 years. The overall survival rate was 95.9% at 3 years. The success rates for single-rooted teeth (71.8%) and multirooted teeth (71.5%) were similar although significantly different (P < 0.001). Best 3-year success rates were found at low (79.7%; <18 years.) and very high age (81.8%; >85 years.). After direct pulp capping, more than two-thirds of the affected teeth did not undergo root canal treatment within 3 years. Although this study has the typical limits of a claims data analysis, it can be concluded that direct pulp capping is an effective intervention to avoid root canal treatment and extraction in a general practice setting. © 2015 International Endodontic Journal.

Following the modern raising of public awareness, the numbers of malpractice litigation are increasing in the health care delivery system in Japan despite the extensive efforts of physicians. Authors reviewed the issues of litigation and the reasons for court decision from the healthcare-related negligence lawsuits in the past 15 years in Japan and investigated the cautionary points for reducing potential litigation. Healthcare-related negligence lawsuits between January 2001 and December 2015 were retrieved and sorted in each clinical field from the database in Courts in Japan and investigated on the proportional factors of the claims and court decisions in the neurosurgical field. During the period, 446 of healthcare-related court decisions including 41 against neurosurgeons (9.2%) were retrieved. Three of 41 decisions retrieved were decisions to retries for lower court decisions. In 38 claims against the neurosurgeons, 26 identified the negligence and 12 dismissed. In 26 decisions in favor of the plaintiffs, identified negligence in diagnosis in 4, clinical judgment in 3, technical skills in 5, clinical management in 7 and process of informed consent in 7. Five out of 18 decisions after 2006 were identified as negligence in an informed consent process, and additional one, who was mainly identified in inadequate technical skills also identified existing an inadequate informed consent process as a fundamental cause of litigation. Neurosurgeons are a higher risk group for malpractice litigation in Japan and adequate informed consent is important to reduce the risk of litigation.

The distribution of medico-legal claims in English anaesthetic practice is unreported. We studied National Health Service Litigation Authority claims related to anaesthesia since 1995. All claims were reviewed by three clinicians and variously categorised, including by type of incident, claimed outcome and cost. Anaesthesia-related claims account for 2.5% of all claims and 2.4% of the value of all claims. Of 841 relevant claims 366 (44%) were related to regional anaesthesia, 245 (29%) obstetric anaesthesia, 164 (20%) inadequate anaesthesia, 95 (11%) dental damage, 71 (8%) airway (excluding dental damage), 63 (7%) drug related (excluding allergy), 31 (4%) drug allergy related, 31 (4%) positioning, 29 (3%) respiratory, 26 (3%) consent, 21 (2%) central venous cannulation and 18 (2%) peripheral venous cannulation. Defining which cases are, from a medico-legal viewpoint, 'high risk' is uncertain, but the clinical categories with the largest number of claims were regional anaesthesia, obstetric anaesthesia, inadequate anaesthesia, dental damage and airway, those with the highest overall cost were regional anaesthesia, obstetric anaesthesia, and airway and those with the highest mean cost per closed claim were respiratory, central venous cannulation and drug error excluding allergy. The data currently available have limitations but offer useful information. A closed claims analysis similar to that in the USA would improve the clinical usefulness of analysis.

The purpose of the research was to conduct a quality indicator analysis of studies investigating peer-tutoring for students with a disability in adapted physical education. An electronic search was conducted among English journals published from 1960 to November 2012. Databases included ERIC, PsycINFO, and SPORTDiscus. Fifteen research studies employing group-experimental (Gersten et al., 2005) or single-subject designs (Horner et al., 2005) met inclusion criteria. Each study was assessed for the presence and clarity of quality indicators. Group designs met an average of 62.5% essential and 69% desirable indicators. An average of 80% of indicators was present for single-subject designs. Results suggest claims of peer-tutoring being an evidence-based practice are premature. Recommendations for clarifying and applying the quality indicators are offered. Copyright © 2013 Elsevier Ltd. All rights reserved.

This study of Department of Defense (DoD) civilian employees Workers' Compensation (WC) claims for chargeback year 2000 through 2012 aimed to analyze the frequency, rates, and costs of WC claims representing 5% of the DoD annual personnel budget. A multiyear cross-sectional study of WC claims data identified the top five most frequent causes, natures, and anatomical sites; changes in frequency, worker age, costs, and time were evaluated for trends. The annual frequency and rate of new DoD WC claims decreased over time, whereas costs per new claim have increased. New claim frequencies, rates, and costs aggregated in older age groups. The increasing trend in costs of each claim and the overall program costs presents a need for case management. Analysis of WC claims data is necessary to help target injury prevention efforts and reduce program costs.

Assess whether Medicare data are useful for monitoring tissue allograft safety and utilization. We used health care claims (billing) data from 2007 for 35 million fee-for-service Medicare beneficiaries, a predominantly elderly population. Using search terms for transplant-related procedures, we generated lists of ICD-9-CM and CPT(®) codes and assessed the frequency of selected allograft procedures. Step 1 used inpatient data and ICD-9-CM procedure codes. Step 2 added non-institutional provider (e.g., physician) claims, outpatient institutional claims, and CPT codes. We assembled preliminary lists of diagnosis codes for infections after selected allograft procedures. Many ICD-9-CM codes were ambiguous as to whether the procedure involved an allograft. Among 1.3 million persons with a procedure ascertained using the list of ICD-9-CM codes, only 1,886 claims clearly involved an allograft. CPT codes enabled better ascertainment of some allograft procedures (over 17,000 persons had corneal transplants and over 2,700 had allograft skin transplants). For spinal fusion procedures, CPT codes improved specificity for allografts; of nearly 100,000 patients with ICD-9-CM codes for spinal fusions, more than 34,000 had CPT codes indicating allograft use. Monitoring infrequent events (infections) after infrequent exposures (tissue allografts) requires large study populations. A strength of the large Medicare databases is the substantial number of certain allograft procedures. Limitations include lack of clinical detail and donor information. Medicare data can potentially augment passive reporting systems and may be useful for monitoring tissue allograft safety and utilization where codes clearly identify allograft use and coding algorithms can effectively screen for infections.

Hospitals' risk-standardized mortality rates and outlier status (significantly higher/lower rates) are reported by the Centers for Medicare and Medicaid Services (CMS) for acute myocardial infarction (AMI) patients using Medicare claims data. New York now has AMI claims data with blood pressure and heart rate added. The objective of this study was to see whether the appended database yields different hospital assessments than standard claims data. New York State clinically appended claims data for AMI were used to create 2 different risk models based on CMS methods: 1 with and 1 without the added clinical data. Model discrimination was compared, and differences between the models in hospital outlier status and tertile status were examined. Mean arterial pressure and heart rate were both significant predictors of mortality in the clinically appended model. The C statistic for the model with the clinical variables added was significantly higher (0.803 vs. 0.773, P<0.001). The model without clinical variables identified 10 low outliers and all of them were percutaneous coronary intervention hospitals. When clinical variables were included in the model, only 6 of those 10 hospitals were low outliers, but there were 2 new low outliers. The model without clinical variables had only 3 high outliers, and the model with clinical variables included identified 2 new high outliers. Appending even a small number of clinical data elements to administrative data resulted in a difference in the assessment of hospital mortality outliers for AMI. The strategy of adding limited but important clinical data elements to administrative datasets should be considered when evaluating hospital quality for procedures and other medical conditions.

Few studies specifically address lawsuits involving Mohs surgery. To better characterize the types of medical professional liability claims involving Mohs surgery. Retrospective legal document review of an online national database. Any legal proceeding involving the search words Mohs and cancer was included. Number of medical professional liability claims involving Mohs surgery for factors including year of litigation, location, physician specialty, injury sustained, cause of legal action, and verdict. Forty-two cases were identified, which occurred from 1989 to 2011. Of the cases identified, 26 involved non-Mohs surgeons as the primary defendant, mostly due to a delay of or failure in diagnosis (n = 16), cosmetic outcome issues (n = 8), lack of informed consent (n = 7), and a delay of or failure in referral to a Mohs surgeon (n = 6). Common causes for litigation against Mohs surgeons as the primary defendant (n = 16) were lack of proper informed consent (n = 5) and cosmetic outcome issues (n = 4). Only 1 case against a Mohs surgeon was judged for the plaintiff. The most common lawsuits pertaining to Mohs surgery list non-Mohs surgeons as the primary defendants. Closer coordination between non-Mohs surgeons and Mohs surgeons may help minimize risk to both parties and lead to better patient care. Small sample size is the primary limitation, in part owing to exclusion of out-of-court settlements from the database.

Large, population-based administrative healthcare databases can be used to identify patients with chronic kidney disease (CKD) when serum creatinine laboratory results are unavailable. We examined the validity of algorithms that used combined hospital encounter and physician claims database codes for the detection of CKD in Ontario, Canada. We accrued 123,499 patients over the age of 65 from 2007 to 2010. All patients had a baseline serum creatinine value to estimate glomerular filtration rate (eGFR). We developed an algorithm of physician claims and hospital encounter codes to search administrative databases for the presence of CKD. We determined the sensitivity, specificity, positive and negative predictive values of this algorithm to detect our primary threshold of CKD, an eGFR <45 mL/min per 1.73 m² (15.4% of patients). We also assessed serum creatinine and eGFR values in patients with and without CKD codes (algorithm positive and negative, respectively). Our algorithm required evidence of at least one of eleven CKD codes and 7.7% of patients were algorithm positive. The sensitivity was 32.7% [95% confidence interval: (95% CI): 32.0 to 33.3%]. Sensitivity was lower in women compared to men (25.7 vs. 43.7%; p <0.001) and in the oldest age category (over 80 vs. 66 to 80; 28.4 vs. 37.6 %; p < 0.001). All specificities were over 94%. The positive and negative predictive values were 65.4% (95% CI: 64.4 to 66.3%) and 88.8% (95% CI: 88.6 to 89.0%), respectively. In algorithm positive patients, the median [interquartile range (IQR)] baseline serum creatinine value was 135 μmol/L (106 to 179 μmol/L) compared to 82 μmol/L (69 to 98 μmol/L) for algorithm negative patients. Corresponding eGFR values were 38 mL/min per 1.73 m² (26 to 51 mL/min per 1.73 m²) vs. 69 mL/min per 1.73 m² (56 to 82 mL/min per 1.73 m²), respectively. Patients with CKD as identified by our database algorithm had distinctly higher baseline serum creatinine values and lower eGFR values than those without such codes. However, because of limited sensitivity, the prevalence of CKD was underestimated.

IMPORTANCE Despite professional recommendations to delay elective colon resection for patients with uncomplicated diverticulitis, early surgery (after <3 preceding episodes) appears to be common. Several factors have been suggested to contribute to early surgery, including increasing numbers of younger patients, a lower threshold to operate laparoscopically, and growing recognition of “smoldering” (or nonrecovering) diverticulitis episodes. However, the relevance of these factors in early surgery has not been well tested, and most prior studies have focused on hospitalizations, missing outpatient events and making it difficult to assess guideline adherence in earlier interventions. OBJECTIVE To describe patterns of episodes of diverticulitis before surgery and factors associated with earlier interventions using inpatient, outpatient, and antibiotic prescription claims. DESIGN, SETTING, AND PARTICIPANTS This investigation was a nationwide retrospective cohort study from January 1, 2009, to December 31, 2012. The dates of the analysis were July 2014 to May 2015. Participants were immunocompetent adult patients (age range, 18-64 years) with incident, uncomplicated diverticulitis. EXPOSURE Elective colectomy for diverticulitis. MAIN OUTCOMES AND MEASURES Inpatient, outpatient, and antibiotic prescription claims for diverticulitis captured in the MarketScan (Truven Health Analytics) databases. RESULTS Of 87 461 immunocompetent patients having at least 1 claim for diverticulitis, 6.4% (n = 5604) underwent a resection. The final study cohort comprised 3054 nonimmunocompromised patients who underwent elective resection for uncomplicated diverticulitis, of whom 55.6% (n = 1699) were male. Before elective surgery, they had a mean (SD) of 1.0 (0.9) inpatient claims, 1.5 (1.5) outpatient claims, and 0.5 (1.2) antibiotic prescription claims related to diverticulitis. Resection occurred after fewer than 3 episodes in 94.9% (2897 of 3054) of patients if counting inpatient claims only, in 80.5% (2459 of 3054) if counting inpatient and outpatient claims only, and in 56.3% (1720 of 3054) if counting all types of claims. Based on all types of claims, patients having surgery after fewer than 3 episodes were of similar mean age compared with patients having delayed surgery (both 47.7 years, P = .91), were less likely to undergo laparoscopy (65.1% [1120 of 1720] vs 70.8% [944 of 1334], P = .001), and had more time between the last 2 episodes preceding surgery (157 vs 96 days, P < .001). Patients with health maintenance organization or capitated insurance plans had lower rates of early surgery (50.1% [247 of 493] vs 57.4% [1429 of 2490], P = .01) than those with other insurance plan types. CONCLUSIONS AND RELEVANCE After considering all types of diverticulitis claims, 56.3% (1720 of 3054) of elective resections for uncomplicated diverticulitis occurred after fewer than 3 episodes. Earlier surgery was not explained by younger age, laparoscopy, time between the last 2 episodes preceding surgery, or financial risk-bearing for patients. In delivering value-added surgical care, factors driving early, elective resection for diverticulitis need to be determined. PMID:26864286

Background The public gets most of its information about genetic research from the media. It has been suggested that media representations may involve exaggeration, called “genohype.” To examine the accuracy and nature of media coverage of genetic research, we reviewed the reporting of single-gene discoveries and associated technologies in major daily newspapers in Canada, the United States, Great Britain and Australia. Methods We used neutral search terms to identify articles about gene discoveries and associated technologies hosted on the Dow Jones Interactive and Canadian NewsDisk databases from January 1995 to June 2001. We compared the contents, claims and conclusions of the scientific journal article with those of the associated newspaper article. Coders subjectively assigned the newspaper articles to 1 of 3 categories: moderately to highly exaggerated claims, slightly exaggerated claims or no exaggerated claims. We used classification tree software to identify the variables that contributed to the assignment of each newspaper article to 1 of the 3 categories: attention structure (positioning in the newspaper and length of the article), authorship, research topic, source of information other than the scientific paper, type and likelihood of risks and benefits, discussion of controversy, valuation tone (positive or negative), framing (e.g., description of research, celebration of progress, report of economic prospects or ethical perspective), technical accuracy (either omissions or errors that changed the description of the methods or interpretation of the results) and use of metaphors. Results We examined 627 newspaper articles reporting on 111 papers published in 24 scientific and medical journals. Only 11% of the newspaper articles were categorized as having moderately to highly exaggerated claims; the majority were categorized as having no claims (63%) or slightly exaggerated claims (26%). The classification analysis ranked the reporting of risks as the most important variable in determining the categorization of newspaper articles. Only 15% of the newspaper articles and 5% of the scientific journal articles discussed costs or risks, whereas 97% of the newspaper articles and 98% of the scientific journal articles discussed the likelihood of benefits of the research. Interpretation Our data suggest that the majority of newspaper articles accurately convey the results of and reflect the claims made in scientific journal articles. Our study also highlights an overemphasis on benefits and under-representation of risks in both scientific and newspaper articles. The cause and nature of this trend is uncertain. PMID:15111473

Women with mental illness are at increased risk of developing and dying from breast cancer and are thus in urgent need of breast cancer preventive care. This study examined the use of screening mammography by Taiwanese women with mental disabilities and analyzed factors affecting this use. 17,243 Taiwanese women with mental disabilities aged 50-69 years were retrospectively included as study subjects. Linked patient data were obtained from three national databases in Taiwan (the 2008 database of physically and mentally disabled persons, the Health Promotion Administration's 2007-2008 mammography screening data, and claims data from the National Health Insurance Research Database). Besides descriptive statistics and bivariate analysis, logistic regression analysis was also performed to examine factors affecting screening mammography use. The 2007-2008 mammography screening rate for Taiwanese women with mental disabilities was 8.79% (n=1515). Variables that significantly influenced screening use were income, education, presence of catastrophic illness/injury, severity of mental disability, and usage of other preventive care services. Screening was positively correlated with income and education. Those with catastrophic illness/injury were more likely to be screened (odds ratio [OR], 1.40; 95% CI=1.15-1.72). Severity of disability was negatively correlated with screening, with very severe, severe, and moderate disability being associated with 0.34-0.69 times the odds of screening as mild disability. In Taiwan, women with mental disabilities receive far less mammography screening than women in general. Copyright © 2014 Elsevier Ltd. All rights reserved.

This study aimed to describe treatment patterns and estimate health care resource utilization and associated costs among Japanese women with dysmenorrhea, using a claims database. This was a retrospective analysis using health insurance data from the Japan Medical Data Center, assessing female patients aged 18-49 years with newly diagnosed primary or secondary dysmenorrhea. Treatment pattern analyses focused on hormonal medications, analgesics, hemostatic agents, traditional Chinese medicine (TCM), and gynecological surgeries. Data were collected on health care resource utilization and costs associated with medications, imaging procedures, and inpatient and outpatient care in both patients and matched controls. The analysis included 6,315 women with dysmenorrhea (3,441 primary; 2,874 secondary). The most commonly prescribed initial therapies were low-dose estrogen progestins (LEPs, 37.7%) and TCM (30.0%), with substantial differences between primary (LEPs: 27.4%, TCM: 38.8%) and secondary (LEPs: 50.2%, TCM: 19.5%) dysmenorrhea cohorts. Surgery was conducted in <5% of all patients. Both primary and secondary cohorts of dysmenorrhea had significantly higher mean total health care costs compared to controls within the 1-year period following diagnosis (Case-primary: 191,680 JPY [1,916 USD]; secondary: 246,488 JPY [2,465 USD], Control-primary: 83,615 JPY [836 USD]; secondary: 90,711 JPY [907 USD]) ( p <0.0001). After adjusting for baseline characteristics, these costs were 2.2 and 2.9 times higher for primary and secondary dysmenorrhea cohorts, respectively, compared with matched controls, (both p <0.0001). The main driver of these excess costs was outpatient care, with eight additional physician visits per year among dysmenorrhea patients compared to controls ( p <0.0001). Considerable heterogeneity in treatment patterns was observed, with relatively low utilization of LEPs in patients with primary dysmenorrhea and those treated by internal medicine physicians. Total annual health care costs were approximately 2-3 times higher in patients with dysmenorrhea compared to women without the condition.

The prevalence of diabetes has increased worldwide. To obtain nationwide data on accountability and utilization of health resources among diabetes patients in Taiwan, an analysis of the claims data for the National Health Insurance (NHI) from 2000 to 2009 was conducted. One-third of the NHI claims database was randomly sampled from 2000 to 2009. Diabetes was defined by three or more outpatient visits with diagnostic codes [International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM): 250 or A code: A181] within 1 year, or one inpatient discharge diagnosis. Accountability items and NHI codes of various metabolic parameters and examinations were identified. Medical utilization was measured by the frequency and cost of care associated with ambulatory visits, hospitalizations, and emergency care within each year. The annual check-up frequency for various examinations significantly increased from 2000 to 2009. Both the average outpatient department (OPD) cost per diabetes patient/year and the average inpatient department (IPD) cost per time increased 1.34-fold in the past decade. The average OPD cost per diabetes patient and average IPD cost of each admission for diabetes patients was four times and 1.4 times compare with the general population, respectively. The annual average medical cost of each diabetes patient affected with both micro- and macrovascular complications was four times compared with those without vascular complications. There was an increasing trend for diabetes patients to visit regional hospital for OPD and IPD, whereas visits to the local hospital decreased in the past decade. Due to the increased frequency of annual check-ups after various examinations, the quality of diabetes management has improved in the past decade in Taiwan. As diabetes patients affected with both micro- and macrovascular complications incurred costs four times compared with those without complications, it is worth screening high-risk individuals to ensure earlier intervention and thus reduce diabetic complications and healthcare expenditure.

The analysis of flood exposure at a national scale for the French insurance market must combine the generation of a probabilistic event set of all possible (but which have not yet occurred) flood situations with hazard and damage modeling. In this study, hazard and damage models are calibrated on a 1995-2010 historical event set, both for hazard results (river flow, flooded areas) and loss estimations. Thus, uncertainties in the deterministic estimation of a single event loss are known before simulating a probabilistic event set. To take into account at least 90 % of the insured flood losses, the probabilistic event set must combine the river overflow (small and large catchments) with the surface runoff, due to heavy rainfall, on the slopes of the watershed. Indeed, internal studies of the CCR (Caisse Centrale de Reassurance) claim database have shown that approximately 45 % of the insured flood losses are located inside the floodplains and 45 % outside. Another 10 % is due to sea surge floods and groundwater rise. In this approach, two independent probabilistic methods are combined to create a single flood loss distribution: a generation of fictive river flows based on the historical records of the river gauge network and a generation of fictive rain fields on small catchments, calibrated on the 1958-2010 Météo-France rain database SAFRAN. All the events in the probabilistic event sets are simulated with the deterministic model. This hazard and damage distribution is used to simulate the flood losses at the national scale for an insurance company (Macif) and to generate flood areas associated with hazard return periods. The flood maps concern river overflow and surface water runoff. Validation of these maps is conducted by comparison with the address located claim data on a small catchment (downstream Argens).

Hospital workers are a diverse population with high rates of musculoskeletal disorders (MSDs). The risk of MSD leading to workers' compensation (WC) claims is likely to show a gradient by socioeconomic status (SES) that may be partly explained by working conditions. A single community hospital provided workforce demographics and WC claim records for 2003-2005. An ergonomic job exposure matrix (JEM) was developed for these healthcare jobs from direct observation of physical workload and extraction of physical and psychosocial job requirements from the O*NET online database. Occupational exposures and SES categories were assigned to workers through their O*NET job titles. Univariate and multivariate Poisson regression analyses were performed to estimate the propensity to file an injury claim in relation to individual factors, occupational exposures, and SES. The jobs with the highest injury rates were nurses, semi-professionals, and semi-skilled. Increased physical work and psychological demands along with low job tenure were associated with an increase in risk, while risk decreased with psychosocial rewards and supervisor support. Both occupational and individual factors mediated the relationship between SES and rate of injury claims. Physical and organizational features of these hospital jobs along with low job tenure predicted WC injury claim risk and explained a substantial proportion of the effects of SES. Further studies that include lifestyle risk factors and control for prior injuries and co-morbidities are warranted to strengthen the current study findings.

This is a descriptive study to analyse overall costs of medical scheme beneficiaries using lipid-lowering agents. The purpose of the analysis was to relate claims for lipid-lowering agents to utilisation and costs of drugs and services. An analysis was undertaken of physician visits, cardiac-related disease co-morbidities and hospitalisation. Any medication or dose changes were also analysed, including those after hospitalisation. A total of 100 691 patients were identified, clustered around the age groups of 40 to 70 years, of whom 60% were males. The cohort consisted ethnically mainly of whites (68%), with an even distribution (6-9%) of Asian, black and Coloured subjects. Of these patients, approximately a third had recorded co-morbidities, mainly hypertension (58.6%) and the more prevalent cardiovascular (ischaemic heart disease, coronary artery disease) and metabolic disorders. While drug costs accounted for approximately 28% of total costs, hospitalisation cost (66%) was by far the greatest cost driver. Whereas drug costs appeared to have decreased over the period of analysis, hospitalisation costs had increased dramatically. Patients appeared to be stable on initial prescribed drug therapy with a relatively low incidence of switching (< 25%), mainly to the generic, simvastatin. Adherence to statin therapy was remarkably high at 85%. Despite the manifold shortcomings, mainly due to the lack of ICD10 coding and information on critical clinical parameters, the study gives some brief insights into the burden of managing patients with cardiovascular diseases and provides a basis for improving future studies.

Telehealth technologies promise to increase access to care, particularly in underserved communities. However, little is known about how private payer reimbursements vary between telehealth and non-telehealth services. We use the largest private claims database in the United States provided by the Health Care Cost Institute to identify telehealth claims and compare average reimbursements to non-telehealth claims. We find average reimbursements for telehealth services are significantly lower than those for non-telehealth for seven of the ten most common services. For example, telehealth reimbursements for office visits for evaluation and management of established patients with low complexity were 30% lower than the corresponding non-telehealth service. Reimbursements by clinical diagnosis code also tended to be lower for telehealth than non-telehealth claims. Widespread adoption of telehealth may be hampered by lower reimbursements for telehealth services relative to face-to-face services. This may result in lower incentives for providers to invest in telehealth technologies that do not result in significant cost savings to their practice, even if telehealth improves patient outcomes.

The self-controlled case series (SCCS) offers potential as an statistical method for risk identification involving medical products from large-scale observational healthcare data. However, analytic design choices remain in encoding the longitudinal health records into the SCCS framework and its risk identification performance across real-world databases is unknown. To evaluate the performance of SCCS and its design choices as a tool for risk identification in observational healthcare data. We examined the risk identification performance of SCCS across five design choices using 399 drug-health outcome pairs in five real observational databases (four administrative claims and one electronic health records). In these databases, the pairs involve 165 positive controls and 234 negative controls. We also consider several synthetic databases with known relative risks between drug-outcome pairs. We evaluate risk identification performance through estimating the area under the receiver-operator characteristics curve (AUC) and bias and coverage probability in the synthetic examples. The SCCS achieves strong predictive performance. Twelve of the twenty health outcome-database scenarios return AUCs >0.75 across all drugs. Including all adverse events instead of just the first per patient and applying a multivariate adjustment for concomitant drug use are the most important design choices. However, the SCCS as applied here returns relative risk point-estimates biased towards the null value of 1 with low coverage probability. The SCCS recently extended to apply a multivariate adjustment for concomitant drug use offers promise as a statistical tool for risk identification in large-scale observational healthcare databases. Poor estimator calibration dampens enthusiasm, but on-going work should correct this short-coming.
Is there a relationship between depression and crying? A review.

To conduct a systematic examination of the relationship between depression and crying by reviewing all relevant theory and empirical data including the performance of crying items in measures of depression. Review of the extant literature on depression and crying using PubMed, PsychInfo and Google Scholar databases. Scores on crying items of depression inventories correlate moderately with overall depression severity. Otherwise, there is surprisingly little evidence for the widespread claim that depression leads to more frequent and/or easier crying. There is also little empirical support for the competing claim that severely depressed individuals lose their capacity to cry. Current claims about the relationship between depression and crying lack a robust empirical foundation. Assessment instruments and diagnostic systems for mood disorders are inconsistent in how they handle crying as a symptom. Further work to investigate the causes and the context of crying in depressed patients is needed.

Background Population-based estimates of the prevalence of thyrotoxicosis (TTX), the frequency of antithyroid drug (ATD) use, and risk of adverse events in pregnant women and their infants are lacking. Therefore, our objective was to obtain epidemiologic estimates of these parameters within a large population-based sample of pregnant women with TTX. Methods A retrospective claims analysis was performed from the MarketScan Commercial Claims and Encounters health insurance database for the period 2005–2009. Women aged 15–44 years, enrolled for at least 2 years, and who had a pregnancy during the study period were included. Diagnosis of TTX was based on International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes using narrow (TTX-1=ICD 242.0) and broad (TTX-2=ICD 242.0 or 242.9) definitions. ATD use was based on prescriptions filled for propylthiouracil (PTU) or methimazole (MMI). Adverse events in mothers and infants were determined from the ICD-9-CM diagnosis codes recorded on submitted claims. Results The database contained 904,497 eligible women. The average yearly prevalence per 1000 pregnant women was 2.46 for TTX-1 and 5.88 for TTX-2. Thirty-nine percent used ATD at any time during the study period. Compared to women without a TTX diagnosis, there was more than a twofold increase for liver disease among women with TTX (odds ratio [OR]=2.08, p<0.001) and a 13% increased risk for congenital anomalies (OR=1.13, p=0.014), but no association was observed with ATD use. The rates of congenital defects (per 1000 infants) associated with ATD use were 55.6 for MMI, 72.1 for PTU, and 65.8 for untreated women with TTX, compared to 58.8 among women without TTX. Conclusions There was some indication of an elevated risk of liver disease and congenital anomalies in women with TTX, but the risk did not appear to be related to the ATD use. There seems to be a higher pregnancy termination rate for women with TTX on MMI, which likely reflects elective pregnancy terminations. PMID:23194469

Objective To determine the bias associated with frequency of visits by physicians in adjusting for illness, using diagnoses recorded in administrative databases. Setting Claims data from the US Medicare program for services provided in 2007 among 306 US hospital referral regions. Design Cross sectional analysis. Participants 20% sample of fee for service Medicare beneficiaries residing in the United States in 2007 (n=5 153 877). Main outcome measures The effect of illness adjustment on regional mortality and spending rates using standard and visit corrected illness methods for adjustment. The standard method adjusts using comorbidity measures based on diagnoses listed in administrative databases; the modified method corrects these measures for the frequency of visits by physicians. Three conventions for measuring comorbidity are used: the Charlson comorbidity index, Iezzoni chronic conditions, and hierarchical condition categories risk scores. Results The visit corrected Charlson comorbidity index explained more of the variation in age, sex, and race mortality across the 306 hospital referral regions than did the standard index (R2=0.21 v 0.11, P<0.001) and, compared with sex and race adjusted mortality, reduced regional variation, whereas adjustment using the standard Charlson comorbidity index increased it. Although visit corrected and age, sex, and race adjusted mortality rates were similar in hospital referral regions with the highest and lowest fifths of visits, adjustment using the standard index resulted in a rate that was 18% lower in the highest fifth (46.4 v 56.3 deaths per 1000, P<0.001). Age, sex, and race adjusted spending as well as visit corrected spending was more than 30% greater in the highest fifth of visits than in the lowest fifth, but only 12% greater after adjustment using the standard index. Similar results were obtained using the Iezzoni and the hierarchical condition categories conventions for measuring comorbidity. Conclusion The rates of visits by physicians introduce substantial bias when regional mortality and spending rates are adjusted for illness using comorbidity measures based on the observed number of diagnoses recorded in Medicare’s administrative database. Adjusting without correction for regional variation in visit rates tends to make regions with high rates of visits seem to have lower mortality and lower costs, and vice versa. Visit corrected comorbidity measures better explain variation in age, sex, and race mortality than observed measures, and reduce observational intensity bias. PMID:23430282

It is well known that the tobacco industry has placed articles in scientific literature to maintain controversy over the dangers of tobacco use, while claiming that smokers are well-informed about risk. This study illuminates an industry attempt to directly undermine popular understanding of the hazards of smoking using an industry-created organization called Associates for Research in the Science of Enjoyment (ARISE). Searches of tobacco industry documents contained in the Legacy Tobacco Documents Library, British American Tobacco Documents Library, and British Columbia's Tobacco Industry documents were performed as well as searches of the LexisNexis database for news articles on ARISE published between 1989 and 2005. Qualitative analysis focused on industry motives, media strategies, and rhetorical tactics; quantitative content analysis focused on media coverage. Between 1989 and 2005, at least 846 articles appeared in the European, Australian, and US press mentioning ARISE, its members, or its activities. Many of these articles presented two themes: smoking was a healthful 'pleasure', and health promotion practices, including cessation, were stressful and unhealthy. Few articles included responses from health advocates, questioned ARISE's claims, or mentioned its funding. ARISE successfully planted stories in the press, designed to allay the health concerns of smokers and to discredit health promotion information and practices. ARISE's later interest in food suggests that counterfactual 'health' messages on almost any topic could be promoted similarly, regardless of their implausibility.

To evaluate the association between objective and subjective knowledge on HIV/AIDS and condom use. Analysis of a database from an anonymous, self-applied, randomized survey conducted between 1995 and 1996. Study subjects were 1,410 adolescents of four socioeconomic strata from Guadalajara, Mexico. Objective knowledge was assessed with 24 questions regarding HIV/AIDS, and subjective knowledge with the question "how much do you think you know about HIV/AIDS?" The variables associated with condom use were identified using logistic regression analysis and by calculating odds ratios with a 95% confidence interval. The degree of objective knowledge was "average", differentiated by socioeconomic strata (p < 0.001), and was higher in adolescents from medium and high socioeconomic strata (p < 0.008). Regarding subjective knowledge, adolescents from the low, medium, and high socioeconomic strata claimed to know "a little", and the ones from the lowest stratum claimed to know "very little". Condom use was higher in males (35.4%), and in adolescents from high socioeconomic strata (p < 0.005), than in females (15.3%) (p < 0.001). Although there was a correlation between objective and subjective knowledge (r = 0.37, p < 0.001), a higher degree of subjective knowledge was associated with condom use (p < 0.001). Subjective knowledge, belonging to medium and high socioeconomic strata and being male, were predictors of condom use.

We reported previously the results of a 6-month controlled trial in which the use of a commercially available electronic prescribing system with integrated clinical decision support and evidence-based message capability was associated with significantly lower primary care drug costs. The original study focused on new prescriptions, defined as claims for a medication that the patient had not received in the previous 12 months. The main objectives of this follow-up report were to (a) determine if the 6-month savings on new prescriptions were sustained during 12 months of follow-up, (b) evaluate the impact of the computerized decision support system (CDSS) on all pharmacy claims and per-member-per-month (PMPM) expenditures, and (c) evaluate the prescribing behaviors within 8 high-cost therapeutic categories that were frequently targeted by the electronic messages to prescribers to help verify that the drug cost savings were due to the recommendations in the electronic prescribing system. Two database queries were performed to identify additional pharmacy claims data for all Network Health Plan patients who were cared for by the 38 primary care clinicians (32 physicians, 4 nurse practitioners, and 2 physician assistants) included in our original 6-month study. This follow-up analysis (a) identified all new prescription claims for the 2 groups of clinicians throughout the 12-month follow-up period (June 2002 through May 2003) and (b) assessed all pharmacy claims during the same 12-month period to provide more complete savings estimates and to examine between-group differences in PMPM expenditures. During 12 months of follow-up, clinicians using the electronic prescribing system continued to have lower prescription costs than the controls. Clinicians using the electronic prescribing system had average costs for 26,674 new prescriptions that were dollar 4.12 lower (95% confidence interval, dollar 1.53-dollar 6.71; P=0.003) and PMPM expenditures that were dollar 0.57 lower than expected based on the changes observed for 24,507 new prescriptions written by clinicians in the control group. The average drug cost savings on new prescriptions were dollar 482 per prescriber per month (PPPM), based upon prescription cost and dollar 465 PPPM based upon PMPM analysis. When all pharmacy claims (156,429) were analyzed, the intervention group.s average prescription cost was dollar 2.57 lower and their PMPM expenditures were dollar 1.07 lower than expected based on the changes observed in the control group. The average drug cost savings on all pharmacy claims were dollar 863 PPPM based on average prescription cost and dollar 873 PPPM based on PMPM analysis. The proportion of prescriptions for highcost drugs that were the target of the CDSS messages to prescribers was a relative 17.5% lower among the intervention group (35.8%) compared with the control group (43.4%; P=0.03). An electronic prescribing system with integrated decision support shifted prescribing behavior away from high-cost therapies and significantly lowered prescription drug costs. The savings associated with altered prescribing behavior offset the monthly subscription cost of the system.

To show how reweighting can correct for unit nonresponse bias in an occupational health surveillance survey by using data from administrative databases in addition to classic sociodemographic data. In 2010, about 10,000 workers covered by a French health insurance fund were randomly selected and were sent a postal questionnaire. Simultaneously, auxiliary data from routine health insurance and occupational databases were collected for all these workers. To model the probability of response to the questionnaire, logistic regressions were performed with these auxiliary data to compute weights for correcting unit nonresponse. Corrected prevalences of questionnaire variables were estimated under several assumptions regarding the missing data process. The impact of reweighting was evaluated by a sensitivity analysis. Respondents had more reimbursement claims for medical services than nonrespondents but fewer reimbursements for medical prescriptions or hospitalizations. Salaried workers, workers in service companies, or who had held their job longer than 6 months were more likely to respond. Corrected prevalences after reweighting were slightly different from crude prevalences for some variables but meaningfully different for others. Linking health insurance and occupational data effectively corrects for nonresponse bias using reweighting techniques. Sociodemographic variables may be not sufficient to correct for nonresponse.

Objectives Neonatal hypoglycaemia is a potential cause of neonatal morbidity, and on rare but tragic occasions causes long-term neurodevelopmental harm with consequent emotional and practical costs for the family. The organisational cost to the NHS includes the cost of successful litigation claims. The purpose of the review was to identify themes that could alert clinicians to common pitfalls and thus improve patient safety. Design The NHS Litigation Authority (NHS LA) Claims Management System was reviewed to identify and review 30 claims for injury secondary to neonatal hypoglycaemia, which were notified to the NHS LA between 2002 and 2011. Setting NHS LA. Patients Anonymised documentation relating to 30 neonates for whom claims were made relating to neonatal hypoglycaemia. Dates of birth were between 1995 and 2010. Interventions Review of documentation held on the NHS LA database. Main outcome measures Identifiable risk factors for hypoglycaemia, presenting clinical signs, possible deficits in care, financial costs of litigation. Results All claims related to babies of at least 36 weeks’ gestation. The most common risk factor for hypoglycaemia was low birth weight or borderline low birth weight, and the most common reported presenting sign was abnormal feeding behaviour. A number of likely deficits in care were reported, all of which were avoidable. In this 10-year reporting period, there were 25 claims for which damages were paid, with a total financial cost of claims to the NHS of £162 166 677. Conclusions Acknowledging that these are likely to be the most rare but most seriously affected cases, the clinical themes arising from these cases should be used for further development of training and guidance to reduce harm and redivert NHS funds from litigation to direct care.

Background: Clinical studies that use observational databases, such as administrative claims and electronic health records, to evaluate the effects of medical products have become commonplace. These studies begin by selecting a particular study design, such as a case control, cohort, or self-controlled design, and different authors can and do choose different designs for the same clinical question. Furthermore, published papers invariably report the study design but do not discuss the rationale for the specific choice. Studies of the same clinical question with different designs, however, can generate different results, sometimes with strikingly different implications. Even within a specific study design, authors make many different analytic choices and these too can profoundly impact results. In this paper, we systematically study heterogeneity due to the type of study design and due to analytic choices within study design. Methods and findings: We conducted our analysis in 10 observational healthcare databases but mostly present our results in the context of the GE Centricity EMR database, an electronic health record database containing data for 11.2 million lives. We considered the impact of three different study design choices on estimates of associations between bisphosphonates and four particular health outcomes for which there is no evidence of an association. We show that applying alternative study designs can yield discrepant results, in terms of direction and significance of association. We also highlight that while traditional univariate sensitivity analysis may not show substantial variation, systematic assessment of all analytical choices within a study design can yield inconsistent results ranging from statistically significant decreased risk to statistically significant increased risk. Our findings show that clinical studies using observational databases can be sensitive both to study design choices and to specific analytic choices within study design. Conclusion: More attention is needed to consider how design choices may be impacting results and, when possible, investigators should examine a wide array of possible choices to confirm that significant findings are consistently identified.

Food composition databases are critical to assess and plan dietary intakes. Dietary supplement databases are also needed because dietary supplements make significant contributions to total nutrient intakes. However, no uniform system exists for classifying dietary supplement products and indexing their ingredients in such databases. Differing approaches to classifying these products make it difficult to retrieve or link information effectively. A consistent approach to classifying information within food composition databases led to the development of LanguaL™, a structured vocabulary. LanguaL™ is being adapted as an interface tool for classifying and retrieving product information in dietary supplement databases. This paper outlines proposed changes to the LanguaL™ thesaurus for indexing dietary supplement products and ingredients in databases. The choice of 12 of the original 14 LanguaL™ facets pertinent to dietary supplements, modifications to their scopes, and applications are described. The 12 chosen facets are: Product Type; Source; Part of Source; Physical State, Shape or Form; Ingredients; Preservation Method, Packing Medium, Container or Wrapping; Contact Surface; Consumer Group/Dietary Use/Label Claim; Geographic Places and Regions; and Adjunct Characteristics of food.

Pediatric radiology malpractice claims - characteristics and comparison to adult radiology claims.
Breen, Micheál A; Dwyer, Kathy; Yu-Moe, Winnie; Taylor, George A
2017-06-01
Medical malpractice is the primary method by which people who believe they have suffered an injury in the course of medical care seek compensation in the United States and Canada. An increasing body of research demonstrates that failure to correctly diagnose is the most common allegation made in malpractice claims against radiologists. Since the 1994 survey by the Society of Chairmen of Radiology in Children's Hospitals (SCORCH), no other published studies have specifically examined the frequency or clinical context of malpractice claims against pediatric radiologists or arising from pediatric imaging interpretation. We hypothesize that the frequency, character and outcome of malpractice claims made against pediatric radiologists differ from those seen in general radiology practice. We searched the Controlled Risk Insurance Co. (CRICO) Strategies' Comparative Benchmarking System (CBS), a private repository of approximately 350,000 open and closed medical malpractice claims in the United States, for claims related to pediatric radiology. We further queried these cases for the major allegation, the clinical environment in which the claim arose, the clinical severity of the alleged injury, indemnity paid (if payment was made), primary imaging modality involved (if applicable) and primary International Classification of Diseases, 9th revision (ICD-9) diagnosis underlying the claim. There were a total of 27,056 fully coded claims of medical malpractice in the CBS database in the 5-year period between Jan. 1, 2010, and Dec. 31, 2014. Of these, 1,472 cases (5.4%) involved patients younger than 18 years. Radiology was the primary service responsible for 71/1,472 (4.8%) pediatric cases. There were statistically significant differences in average payout for pediatric radiology claims ($314,671) compared to adult radiology claims ($174,033). The allegations were primarily diagnosis-related in 70% of pediatric radiology claims. The most common imaging modality implicated in pediatric radiology claims was radiography. The highest payouts in pediatric radiology pertained to missed congenital and developmental anomalies (average $1,222,932) such as developmental dysplasia of the hip and congenital central nervous system anomalies. More than half of pediatric radiology claims arose in the ambulatory setting. Pediatric radiology is not immune from claims of medical malpractice and these claims result in high monetary payouts, particularly for missed diagnoses of congenital and developmental anomalies. Our data suggest that efforts to reduce diagnostic error in the outpatient radiology setting, in the interpretation of radiographs, and in the improved diagnosis of fractures and congenital and developmental anomalies would be of particular benefit to the pediatric radiology community.
A Review of Calibration Transfer Practices and Instrument Differences in Spectroscopy.
Workman, Jerome J
2018-03-01
Calibration transfer for use with spectroscopic instruments, particularly for near-infrared, infrared, and Raman analysis, has been the subject of multiple articles, research papers, book chapters, and technical reviews. There has been a myriad of approaches published and claims made for resolving the problems associated with transferring calibrations; however, the capability of attaining identical results over time from two or more instruments using an identical calibration still eludes technologists. Calibration transfer, in a precise definition, refers to a series of analytical approaches or chemometric techniques used to attempt to apply a single spectral database, and the calibration model developed using that database, for two or more instruments, with statistically retained accuracy and precision. Ideally, one would develop a single calibration for any particular application, and move it indiscriminately across instruments and achieve identical analysis or prediction results. There are many technical aspects involved in such precision calibration transfer, related to the measuring instrument reproducibility and repeatability, the reference chemical values used for the calibration, the multivariate mathematics used for calibration, and sample presentation repeatability and reproducibility. Ideally, a multivariate model developed on a single instrument would provide a statistically identical analysis when used on other instruments following transfer. This paper reviews common calibration transfer techniques, mostly related to instrument differences, and the mathematics of the uncertainty between instruments when making spectroscopic measurements of identical samples. It does not specifically address calibration maintenance or reference laboratory differences.

Surgical exposure during total knee arthroplasty (TKA) requires mobilization technique of the patella. Proponents of minimally invasive TKA claim that lateral retraction, rather than eversion, of the patella may be beneficial. Many randomized controlled studies attempt to identify this issue; however, no final conclusion arrives. With this systemic review and meta-analysis, we intended to test whether patella eversion during TKA had deleterious effects. A comprehensive literature search was performed in PubMed, MEDLINE, EMBASE and other internet database. We retrieved all the relevant studies designed to interpret this issue. The searching time frame was from the establishing of these databases until July 2014. Six randomized controlled trials assessing a total of 414 patients and 451 knees were included. The duration of surgery was much shorter (p = 0.003), and the length of skin incision was much longer (p < 0.00001). No significant difference was found on other measurements, including length of hospital stay, quadriceps strength, complications, straight leg raise, Visual Analogue Scale score and functional scores. Patella eversion could decrease the duration of the surgery; nevertheless, the length of skin incision was longer; no significant difference was found on other measurements, especially the quadriceps strength and complications which were concerned. Patella eversion and patella lateral retraction could achieve similar clinical outcomes. Systematic review and meta-analysis, Level I.

This study aimed to determine whether a multi-faceted model of management of work related musculoskeletal disorders reduced compensation claim costs and days of compensation for injured workers. An intervention including early reporting, employee centred case management and removal of barriers to return to work was instituted in 16 selected companies with a combined remuneration over $337 million. Outcomes were evaluated by an administrative dataset from the Victorian WorkCover Authority database. A 'quasi experimental' pre-post design was employed with 492 matched companies without the intervention used as a control group and an average of 21 months of post-intervention follow-up. Primary outcomes were average number of days of compensation and average cost of claims. Secondary outcomes were total medical costs and weekly benefits paid. Information on 3,312 claims was analysed. In companies where the intervention was introduced the average cost of claims was reduced from $6,019 to $3,913 (estimated difference $2,329, 95 % CI $1,318-$3,340) and the number of days of compensation decreased from 33.5 to 14.1 (HR 0.77, 95 % CI 0.67-0.88). Medical costs and weekly benefits costs were also lower after the intervention (p < 0.05). Reduction in claims costs were noted across industry types, injury location and most employer sizes. The model of claims management investigated was effective in reducing the number of days of compensation, total claim costs, total medical costs and the amount paid in weekly benefits. Further research should investigate whether the intervention improves non-financial outcomes in the return to work process.

Electronic nicotine delivery systems (ENDS), or e-cigarettes, are heavily marketed online. The purpose of our study was to perform a systematic identification and evaluation of claims made within ENDS retailer and manufacturer websites, and the legal status of such claims. We employed a systematic search protocol with popular search engines using 6 terms: (1) e-cigarettes; (2) e-cigs; (3) e-juice; (4) e-liquid; (5) e-hookah; and (6) vape pen. We analyzed English-language websites where ENDS are sold for implicit and explicit health-related claims. A legal analysis determined whether such claims are permissible under the US Food and Drug Administration's regulations. The vast majority of ENDS manufacturer (N = 78) and retailer (N = 32) websites made at least one health-related claim (77% and 65%, respectively). Modified risk claims and secondhand smoke-related claims were most prevalent, with an average of 2 claims per site. Health-related claims are plentiful within ENDS manufacturer and retailer websites. Results demonstrate that these sites focus on potential benefits while minimizing or eliminating information about possible harmful effects of ENDS. These claims are subject to the current regulatory authority by the FDA, and pose a risk of misinforming consumers.

While the clinical benefits of dalfampridine extended-release (D-ER) have been established in patients with multiple sclerosis (MS) through multiple clinical trials, there is limited real-world data on D-ER use, in particular the persistent use of D-ER, and associated acute care resource utilization and costs. To examine the real-world association of D-ER use and inpatient admissions and costs among patients with MS. This study was a retrospective observational claims analysis of the MarketScan database (April 2009-March 2014). Eligible patients consisted of adult enrollees aged 18-64 years who had (a) 12 months of continuous private plan enrollment preceding (baseline) and following (follow-up) the first D-ER claim; (b) ≥ 2 MS diagnosis codes with ≥ 1 during the baseline period; (c) ≥ 2 consecutive D-ER claims; and (d) no alternate gait-impairing etiologies during the baseline and follow-up periods. Patients were separated into 2 D-ER cohorts in the main analysis: persistent (≥ 360 days of D-ER supply) and nonpersistent (< 360 days of supply) users. Sensitivity analyses were conducted, examining additional breakdowns of days of supply within the nonpersistent cohort. Inpatient admissions (all-cause and MS-related) and health care expenditures were calculated and compared between the cohorts during follow-up using Wilcoxon rank-sum and chi-square tests. Regression models were conducted, controlling for age, sex, MS relapses, comorbidities, disease-modifying therapy use, and other baseline factors, including inpatient admissions and costs. Of 1,598 eligible patients, 719 (45.0%) were persistent D-ER users, and 879 (55.0%) were nonpersistent D-ER users. The 2 cohorts had similar demographic and clinical characteristics, with mean (SD) ages of 51.0 (8.4) and 50.6 (8.6) years and were 71.3% and 66.6% female, respectively. Compared with nonpersistent D-ER use, persistent D-ER use was associated with lower odds of all-cause inpatient admissions (OR = 0.58, P = 0.010) and MS-related inpatient admissions (OR = 0.50, P = 0.004). Persistent use was also associated with lower inpatient expenditures for all-cause admissions ($669 vs. $1,515, P = 0.002) and MS-related admissions ($388 vs. $891, P = 0.008). Persistent D-ER use was associated with significantly lower rates of all-cause and MS-related inpatient admissions and costs.

To compare the annual cost of statins in the United States and in the United Kingdom. Matched-cohort cost analysis. U.K. General Practice Research Database (GPRD), and MarketScan Commercial Claims and Encounters Database, a large, U.S. self-insured medical claims database. We initially identified 1.6 million people in the GPRD who were younger than 65 years of age in 2005. These people were then matched by year of birth and sex with 1.6 million people in the U.S. database. From this matched pool, we estimated that 280,000 people aged 55-64 years from each country in 2005 were prescribed at least one drug. Of these, 91,474 (33%) in the U.S. were prescribed a statin compared with 68,217 (24%) in the U.K. After excluding those who did not receive statins continuously or who switched statins during the year, there remained 61,470 in the U.S. and 45,788 in the U.K. who were prescribed a single statin preparation continuously during 2005 (annual statin users). We estimated and compared drug costs (presented in 2005 U.S. dollars) separately in the two countries. Estimated drug costs were determined by random sampling. Estimated annual costs/patient in the U.S. ranged from $313 for generic lovastatin to $1428 for nongeneric simvastatin. In the U.K., annual costs/patient ranged from $164 for generic simvastatin to $509 for nongeneric atorvastatin. The total annual cost of the continuous receipt of statins in the U.S. was $64.9 million compared with $15.7 million in the U.K. In June 2006, after our study results were analyzed, the U.S. Food and Drug Administration approved generic simvastatin. We thus derived cost estimates for simvastatin use during 2006 and found that more than 60% of simvastatin users switched to the generic product, which reduced the cost/pill by more than 50%. The cost paid for statins in the U.S. for people younger than 65 years, who were insured by private companies, was approximately 400% higher than comparable costs paid by the government in the U.K. Available generic statins were substantially less expensive than those that were still under patent in both countries. © 2012, Pharmacotherapy Publications, Inc.

To estimate the national prevalence and racial/ethnic differences in psychiatric diagnoses and pharmacologic treatment in a US Medicaid beneficiary population of youth with systemic lupus erythematosus (SLE). We included youth aged 10 to 18 years with a diagnosis of SLE (defined as ≥ 3 outpatient visit claims with an International Classification of Diseases, 9th ed. code of 710.0, each > 30 days apart) in the US Medicaid Analytic Extract database from 2006 and 2007. This database contains all inpatient and outpatient Medicaid claims from 49 states and the District of Columbia. We calculated the prevalence of psychiatric diagnoses and treatment, and used logistic regression to compare depression and anxiety diagnoses, antidepressant, and anxiolytic use among racial/ethnic groups. Of 970 youth with SLE, 15% were white, 42% were African American, 27% were Latino, and 16% were of other races/ethnicities. Diagnoses of depression were present for 19%, anxiety for 7%, acute stress/adjustment for 6%, and other psychiatric disorders for 18%. Twenty percent were prescribed antidepressants, 7% were prescribed anxiolytics, 6% were prescribed antipsychotics, and 5% were prescribed stimulants. In adjusted analyses, African Americans were less likely than whites to be diagnosed with depression (OR 0.56, 95% CI 0.34-0.90) or anxiety (OR 0.49, 95% CI 0.25-0.98), or to be prescribed anxiolytics (OR 0.23, 95% CI 0.11-0.48). We present population-level estimates showing high psychiatric morbidity in youth with SLE, but less prevalent diagnosis and treatment in African Americans. Mental health interventions should address potential racial/ethnic disparities in care.

Permanent hypocalcaemia is the most common and serious complication after total thyroidectomy (TT). This study examined the impact of central neck dissection (CND) and institutional volume on rates of permanent hypocalcaemia by analysing data held in the nationwide claim database of South Korea. Data from patients who underwent TT due to thyroid carcinoma from 2007-2013 were obtained from the Health Insurance Review and Assessment Service database. Of these, patients prescribed more than 1000 mg of elemental calcium for more than 288 days during the first 360 days postsurgery were defined as having permanent hypocalcaemia. In total, 192 333 patients (32 988 male and 159 345 female) were eligible for analysis. Of these, 52 707 (27·4%) underwent TT alone and 139 626 (72·6%) underwent TT plus CND. The incidence of permanent hypocalcaemia was greater in the TT plus CND group than in the TT alone group (5·4% vs 4·6%, P < 0·001). The age- and sex-adjusted risk for permanent hypocalcaemia in the TT plus CND group was 1·20 (P < 0·001). CND did not raise the rates of permanent hypocalcaemia in institutes with a low volume of annual cases (<200), whereas permanent hypocalcaemia was more common in the TT plus CND group than in the TT alone group (3·5% vs 2·9%, P = 0·002) in institutes with a large volume of annual cases (≥800). TT plus CND was associated with a greater risk of permanent hypocalcaemia than TT alone. Surgeons should consider the risk of permanent hypocalcaemia when deciding whether to perform CND. © 2016 John Wiley & Sons Ltd.

Despite the prevalence of therapies available to patients at highest coronary heart disease risk, only a minority of type 2 diabetes mellitus (T2DM) patients reach desired cholesterol treatment levels, with limited data regarding their outcomes. To examine "real-world" effectiveness of initiating treatment with either colesevelam or ezetimibe among individuals with evidence of T2DM and hypercholesterolemia (HCh). Key outcomes included treatment patterns and cardiovascular (CV) events. This retrospective administrative claims-based study utilized medical, pharmacy, and enrollment data linked to laboratory results information from a large United States health plan (January 1, 2006, to March 31, 2011) and included individuals with recorded evidence of T2DM and HCh. The index date was the date of first pharmacy claim for colesevelam or ezetimibe, with cohort assignment based on index medication. Assessments included baseline characteristics, follow-up treatment patterns, and composite CV event, with propensity score matching to correct for sample selection bias. In total, 4231 individuals were identified with evidence of HCh and T2DM (ezetimibe n = 3384; colesevelam n = 847). After matching, the baseline characteristics between cohorts were rendered to be similar. Mean days of persistent medication use was lower with colesevelam compared with ezetimibe (P < 0.001). Compared with ezetimibe, a smaller percentage of individuals in the colesevelam cohort experienced a follow-up composite CV event, and adjusted Cox model results suggested decreased risk (hazard ratio = 0.58; P = 0.004) of a follow-up composite CV event. In this health care database analysis among patients with HCh and T2DM, colesevelam was associated with decreased risk of a composite CV event compared with ezetimibe, despite lower persistence. © The Author(s) 2014.

Abstract Objective To validate a risk index that estimates the likelihood of overdose or serious opioid-induced respiratory depression (OIRD) among medical users of prescription opioids. Subjects and Methods A case-control analysis of 18,365,497 patients with an opioid prescription from 2009 to 2013 in the IMS PharMetrics Plus commercially insured health plan claims database (CIP). An OIRD event occurred in 7,234 cases. Four controls were selected per case. Validity of the Risk Index for Overdose or Serious Opioid-induced Respiratory Depression (RIOSORD), developed previously using Veterans Health Administration (VHA) patient data, was assessed. Multivariable logistic regression was used within the CIP study population to develop a slightly refined RIOSORD. The composition and performance of the CIP-based RIOSORD was evaluated and compared with VHA-based RIOSORD. Results VHA-RIOSORD performed well in discriminating OIRD events in CIP (C-statistic = 0.85). Additionally, re-estimation of logistic model coefficients in CIP yielded a 0.90 C-statistic. The resulting comorbidity and pharmacotherapy variables most highly associated with OIRD and retained in the CIP-RIOSORD were largely concordant with VHA-RIOSORD. These variables included neuropsychiatric and cardiopulmonary disorders, impaired drug excretion, opioid characteristics, and concurrent psychoactive medications. The average predicted probability of OIRD ranged from 2% to 83%, with excellent agreement between predicted and observed incidence across risk classes. Conclusions RIOSORD had excellent predictive accuracy in a large population of US medical users of prescription opioids, similar to its performance in VHA. This practical risk index is designed to support clinical decision-making for safer opioid prescribing, and its clinical utility should be evaluated prospectively. PMID:28340046

Assess algorithms for linking patients across de-identified databases without compromising confidentiality. Hospital discharges from 11 Mayo Clinic hospitals during January 2008-September 2012 (assessment and validation data). Minnesota death certificates and hospital discharges from 2009 to 2012 for entire state (application data). Cross-sectional assessment of sensitivity and positive predictive value (PPV) for four linking algorithms tested by identifying readmissions and posthospital mortality on the assessment data with application to statewide data. De-identified claims included patient gender, birthdate, and zip code. Assessment records were matched with institutional sources containing unique identifiers and the last four digits of Social Security number (SSNL4). Gender, birthdate, and five-digit zip code identified readmissions with a sensitivity of 98.0 percent and a PPV of 97.7 percent and identified postdischarge mortality with 84.4 percent sensitivity and 98.9 percent PPV. Inclusion of SSNL4 produced nearly perfect identification of readmissions and deaths. When applied statewide, regions bordering states with unavailable hospital discharge data had lower rates. Addition of SSNL4 to administrative data, accompanied by appropriate data use and data release policies, can enable trusted repositories to link data with nearly perfect accuracy without compromising patient confidentiality. States maintaining centralized de-identified databases should add SSNL4 to data specifications. © Health Research and Educational Trust.

There has been a surge in the academic publication output based on secondary analyses of the data from the Taiwan's National Health Insurance claim records. It has become a challenge to comprehend such a rapid expansion of the literature. Therefore, this study aimed to explore the conceptual content of National Health Insurance Research Database-based cancer research, using the abstract of articles extracted from PubMed between 2002 and 2015. Search terms including "National Health Insurance Research Database (NHIRD) AND Taiwan," "Taiwan AND population-based," and "Taiwan AND nationwide" were used to search in PubMed with the publication date limited to between 1997 and 2015. The retrieved articles were manually screened to retain only those that were cancer-related and were based on secondary data analysis of the NHIRD. A total 589 articles were selected for subsequent text mining using the R software. Among the 589 articles, the top 5 most studied cancer types were breast (16.3%), lung (11.4%), colorectal (10.4%), liver (8.3%), and prostate (7.5%). The articles that received the highest number of citations by PubMed Central articles were cited 92 times. The top 3 most frequently occurred keywords in the abstracts of the 589 articles were cancer, patient, and risk, with 3670, 2535, and 1652 times, respectively. Analysis of key conception indicated that the most common conceptions were diabetes, survival, breast cancer, lung cancer, and colorectal cancer. In conclusion, in this study of 589 published articles on secondary data analysis of the NHIRD, indexed by PubMed between 2002 and 2015, we found that while the risk factors of cancer, treatment of cancer, and survival of cancer patients were popular research topics, end-of-life cancer care issues were less studied. Further studies should explore these areas since they are as important as treatment of the disease itself for many patients.

With aging and obesity trends, the incidence and prevalence of osteoarthritis (OA) is expected to rise in Canada, increasing the demand for health resources. Resource planning to meet this increasing need requires estimates of the anticipated number of OA patients. Using administrative data from Alberta, we estimated OA incidence and prevalence rates and examined their sensitivity to alternative case definitions. We identified cases in a linked data set spanning 1993 to 2010 (population registry, Discharge Abstract Database, physician claims, Ambulatory Care Classification System, and prescription drug data) using diagnostic codes and drug identification numbers. In the base case, incident cases were captured for patients with an OA diagnostic code for at least 2 physician visits within 2 years or any hospital admission. Seven alternative case definitions were applied and compared. Age- and sex-standardized incidence and prevalence rates were estimated to be 8.6 and 80.3 cases per 1,000 population, respectively, in the base case. Physician claims data alone captured 88% of OA cases. Prevalence rate estimates required 15 years of longitudinal data to plateau. Compared to the base case, estimates are sensitive to alternative case definitions. Administrative databases are a key source for estimating the burden and epidemiologic trends of chronic diseases such as OA in Canada. Despite their limitations, these data provide valuable information for estimating disease burden and planning health services. Estimates of OA are mostly defined through physician claims data and require a long period of longitudinal data. © 2015, American College of Rheumatology.

Little published literature exists regarding malignancy risk in pediatric psoriasis patients. To compare malignancy risk in biologic-naïve pediatric psoriasis patients with a matched pediatric population without psoriasis. This retrospective cohort study used IMS LifeLink Health Plan Claims data covering 1998-2008. Cancer incidence was compared with the US Surveillance, Epidemiology, and End Results (SEER) data using standardized incidence ratios (SIR), and between cohorts using Cox models. Among 9045 pediatric psoriasis patients and 77,206 comparators, 18 probable or highly probable cancers were identified. Pediatric psoriasis patients had a nonsignificantly lower incidence than comparators (hazard ratio [HR] 0.43, 95% confidence interval [CI] 0.05-3.54). The HR increased to 1.67 (95% CI 0.54-5.18) when cancer diagnosed during the first 90 days of follow-up was included. The pediatric psoriasis cohort had a significantly increased lymphoma rate compared with SEER (SIR 5.42, 95% CI 1.62-12.94), but no significant increase relative to the comparator cohort. Misclassification of disease and outcome might have occurred with patients in the claims database. Patients with pediatric psoriasis showed no significant increase in overall cancer risk compared with those without psoriasis. A potential increased risk for lymphoma was observed when compared with the general population. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

Background Hospital workers are a diverse population with high rates of musculoskeletal disorders (MSDs). The risk of MSD leading to workers’ compensation (WC) claims is likely to show a gradient by socioeconomic status (SES) that may be partly explained by working conditions. Methods A single community hospital provided workforce demographics and WC claim records for 2003–2005. An ergonomic job exposure matrix (JEM) was developed for these healthcare jobs from direct observation of physical workload and extraction of physical and psychosocial job requirements from the O*NET online database. Occupational exposures and SES categories were assigned to workers through their O*NET job titles. Univariate and multivariate Poisson regression analyses were performed to estimate the propensity to file an injury claim in relation to individual factors, occupational exposures, and SES. Results The jobs with the highest injury rates were nurses, semi-professionals, and semi-skilled. Increased physical work and psychological demands along with low job tenure were associated with an increase in risk, while risk decreased with psychosocial rewards and supervisor support. Both occupational and individual factors mediated the relationship between SES and rate of injury claims. Conclusions Physical and organizational features of these hospital jobs along with low job tenure predicted WC injury claim risk and explained a substantial proportion of the effects of SES. Further studies that include lifestyle risk factors and control for prior injuries and co-morbidities are warranted to strengthen the current study findings. PMID:19479820

Introduction Tracking and trending rates of injuries and illnesses classified as musculoskeletal disorders caused by ergonomic risk factors such as overexertion and repetitive motion (MSDs) and slips, trips, or falls (STFs) in different industry sectors is of high interest to many researchers. Unfortunately, identifying the cause of injuries and illnesses in large datasets such as workers’ compensation systems often requires reading and coding the free form accident text narrative for potentially millions of records. Method To alleviate the need for manual coding, this paper describes and evaluates a computer auto-coding algorithm that demonstrated the ability to code millions of claims quickly and accurately by learning from a set of previously manually coded claims. Conclusions The auto-coding program was able to code claims as a musculoskeletal disorders, STF or other with approximately 90% accuracy. Impact on industry The program developed and discussed in this paper provides an accurate and efficient method for identifying the causation of workers’ compensation claims as a STF or MSD in a large database based on the unstructured text narrative and resulting injury diagnoses. The program coded thousands of claims in minutes. The method described in this paper can be used by researchers and practitioners to relieve the manual burden of reading and identifying the causation of claims as a STF or MSD. Furthermore, the method can be easily generalized to code/classify other unstructured text narratives. PMID:23206504

The aim of this study was to develop and validate an insurance claims-based algorithm for identifying urinary retention (UR) in epilepsy patients receiving antiepileptic drugs to facilitate safety monitoring. Data from the HealthCore Integrated Research Database(SM) in 2008-2011 (retrospective) and 2012-2013 (prospective) were used to identify epilepsy patients with UR. During the retrospective phase, three algorithms identified potential UR: (i) UR diagnosis code with a catheterization procedure code; (ii) UR diagnosis code alone; or (iii) diagnosis with UR-related symptoms. Medical records for 50 randomly selected patients satisfying ≥1 algorithm were reviewed by urologists to ascertain UR status. Positive predictive value (PPV) and 95% confidence intervals (CI) were calculated for the three component algorithms and the overall algorithm (defined as satisfying ≥1 component algorithms). Algorithms were refined using urologist review notes. In the prospective phase, the UR algorithm was refined using medical records for an additional 150 cases. In the retrospective phase, the PPV of the overall algorithm was 72.0% (95%CI: 57.5-83.8%). Algorithm 3 performed poorly and was dropped. Algorithm 1 was unchanged; urinary incontinence and cystitis were added as exclusionary diagnoses to Algorithm 2. The PPV for the modified overall algorithm was 89.2% (74.6-97.0%). In the prospective phase, the PPV for the modified overall algorithm was 76.0% (68.4-82.6%). Upon adding overactive bladder, nocturia and urinary frequency as exclusionary diagnoses, the PPV for the final overall algorithm was 81.9% (73.7-88.4%). The current UR algorithm yielded a PPV > 80% and could be used for more accurate identification of UR among epilepsy patients in a large claims database. Copyright © 2016 John Wiley & Sons, Ltd.

Cluster analysis (CA) is a frequently used applied statistical technique that helps to reveal hidden structures and "clusters" found in large data sets. However, this method has not been widely used in large healthcare claims databases where the distribution of expenditure data is commonly severely skewed. The purpose of this study was to identify cost change patterns of patients with end-stage renal disease (ESRD) who initiated hemodialysis (HD) by applying different clustering methods. A retrospective, cross-sectional, observational study was conducted using the Truven Health MarketScan® Research Databases. Patients aged ≥18 years with ≥2 ESRD diagnoses who initiated HD between 2008 and 2010 were included. The K-means CA method and hierarchical CA with various linkage methods were applied to all-cause costs within baseline (12-months pre-HD) and follow-up periods (12-months post-HD) to identify clusters. Demographic, clinical, and cost information was extracted from both periods, and then examined by cluster. A total of 18,380 patients were identified. Meaningful all-cause cost clusters were generated using K-means CA and hierarchical CA with either flexible beta or Ward's methods. Based on cluster sample sizes and change of cost patterns, the K-means CA method and 4 clusters were selected: Cluster 1: Average to High (n = 113); Cluster 2: Very High to High (n = 89); Cluster 3: Average to Average (n = 16,624); or Cluster 4: Increasing Costs, High at Both Points (n = 1554). Median cost changes in the 12-month pre-HD and post-HD periods increased from $185,070 to $884,605 for Cluster 1 (Average to High), decreased from $910,930 to $157,997 for Cluster 2 (Very High to High), were relatively stable and remained low from $15,168 to $13,026 for Cluster 3 (Average to Average), and increased from $57,909 to $193,140 for Cluster 4 (Increasing Costs, High at Both Points). Relatively stable costs after starting HD were associated with more stable scores on comorbidity index scores from the pre-and post-HD periods, while increasing costs were associated with more sharply increasing comorbidity scores. The K-means CA method appeared to be the most appropriate in healthcare claims data with highly skewed cost information when taking into account both change of cost patterns and sample size in the smallest cluster.

The aim of this study was to compare the frequency and liability costs associated with radiology malpractice claims relative to other medical services and to evaluate the clinical context and case disposition associated with radiology malpractice claims. This HIPAA-compliant study was exempted from institutional review board approval. The Comparative Benchmarking System database, a repository of more than 300,000 medical malpractice cases in the United States, was queried for closed claims over a five-year period (2008-2012). Claims were categorized by the medical service primarily responsible for the claim and the paid total loss. For all cases in which radiology was the primary responsible service, the case abstracts were evaluated to determine injury severity, claimant type by setting, claim allegation, process of care involved, case disposition, modality involved, and body section. Intracategory comparisons were made on the basis of the frequency of indemnity payment and total indemnity payment for paid cases, using χ(2) and Wilcoxon rank-sum tests. Radiology was the eighth most likely responsible service to be implicated in a medical malpractice claim, with a median total paid loss (indemnity payment plus defense cost plus administrative expense) per closed case of $30,091 (mean, $205,619 ± $508,883). Radiology claims were most commonly associated with high- and medium-severity injuries (93.3% [820 of 879]; 95% confidence interval [CI], 91.7%-94.95%), the outpatient setting (66.3% [581 of 876]; 95% CI, 63.0%-69.2%), and diagnosis-related allegations (ie, failure to diagnose or delayed diagnosis) (57.3% [504 of 879]; 95% CI, 54.0%-60.6%). A high proportion of claims pertained to cancer diagnoses (44.0% [222 of 504]; 95% CI, 39.7%-48.3%). A total of 62.3% (548 of 879; 95% CI, 59.1%-65.5%) of radiology claims were closed without indemnity payments; 37.7% (331 of 879; 95% CI, 34.5%-40.9%) were closed with a median indemnity payment of $175,000 (range, $112-$6,691,762; mean $481,094 ± $727,636). Radiology malpractice claims most commonly involve diagnosis-related allegations in the outpatient setting, particularly cancer diagnoses, with approximately one-third of claims resulting in payouts to the claimants.

Repeat workers' compensation claims: risk factors, costs and work disability
2011-01-01
Background The objective of our study was to describe factors associated with repeat workers' compensation claims and to compare the work disability arising in workers with single and multiple compensation claims. Methods All initial injury claims lodged by persons of working age during a five year period (1996 to 2000) and any repeat claims were extracted from workers' compensation administrative data in the state of Victoria, Australia. Groups of workers with single and multiple claims were identified. Descriptive analysis of claims by affliction, bodily location, industry segment, occupation, employer and workplace was undertaken. Survival analysis determined the impact of these variables on the time between the claims. The economic impact and duration of work incapacity associated with initial and repeat claims was compared between groups. Results 37% of persons with an initial claim lodged a second claim. This group contained a significantly greater proportion of males, were younger and more likely to be employed in manual occupations and high-risk industries than those with single claims. 78% of repeat claims were for a second injury. Duration between the claims was shortest when the working conditions had not changed. The initial claims of repeat claimants resulted in significantly (p < 0.001) lower costs and work disability than the repeat claims. Conclusions A substantial proportion of injured workers experience a second occupational injury or disease. These workers pose a greater economic burden than those with single claims, and also experience a substantially greater cumulative period of work disability. There is potential to reduce the social, health and economic burden of workplace injury by enacting prevention programs targeted at these workers. PMID:21696637

The use of full-population databases is under-explored to study the use, quality and costs of end-of-life care. Using the case of Belgium, we explored: (1) which full-population databases provide valid information about end-of-life care, (2) what procedures are there to use these databases, and (3) what is needed to integrate separate databases. Technical and privacy-related aspects of linking and accessing Belgian administrative databases and disease registries were assessed in cooperation with the database administrators and privacy commission bodies. For all relevant databases, we followed procedures in cooperation with database administrators to link the databases and to access the data. We identified several databases as fitting for end-of-life care research in Belgium: the InterMutualistic Agency's national registry of health care claims data, the Belgian Cancer Registry including data on incidence of cancer, and databases administrated by Statistics Belgium including data from the death certificate database, the socio-economic survey and fiscal data. To obtain access to the data, approval was required from all database administrators, supervisory bodies and two separate national privacy bodies. Two Trusted Third Parties linked the databases via a deterministic matching procedure using multiple encrypted social security numbers. In this article we describe how various routinely collected population-level databases and disease registries can be accessed and linked to study patterns in the use, quality and costs of end-of-life care in the full population and in specific diagnostic groups.

The central role of the propensity score analysis (PSA) in observational studies is for causal inference; as such, PSA is often used for making causal claims in research articles. However, there are still some issues for researchers to consider when making claims of causality using PSA results. This summary first briefly reviews PSA, followed by…
The Clinical and Economic Burden of Hyperkalemia on Medicare and Commercial Payers
Fitch, Kathryn; Woolley, J. Michael; Engel, Tyler; Blumen, Helen

Background Hyperkalemia (serum potassium >5.0 mEq/L) may be caused by reduced kidney function and drugs affecting the renin-angiotensin-aldosterone system and is often present in patients with chronic kidney disease (CKD). Objective To quantify the burden of hyperkalemia in US Medicare fee-for-service and commercially insured populations using real-world claims data, focusing on prevalence, comorbidities, mortality, medical utilization, and cost. Methods A descriptive, retrospective claims data analysis was performed on patients with hyperkalemia using the 2014 Medicare 5% sample and the 2014 Truven Health Analytics MarketScan Commercial Claims and Encounter databases. The starting study samples required patient insurance eligibility during ≥1 months in 2014. The identification of hyperkalemia and other comorbidities required having ≥1 qualifying claims in 2014 with an appropriate International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code in any position. To address the differences between patients with and without hyperkalemia, CKD subsamples were analyzed separately. Mortality rates were calculated in the Medicare sample population only. The claims were grouped into major service categories; the allowed costs reflected all costs incurred by each cohort divided by the total number of member months for that cohort. Results The prevalence of hyperkalemia in the Medicare and commercially insured samples was 2.3% and 0.09%, respectively. Hyperkalemia was associated with multiple comorbidities, most notably CKD. The prevalence of CKD in the Medicare and the commercially insured members with hyperkalemia was 64.8% and 31.8%, respectively. After adjusting for CKD severity, the annual mortality rate for Medicare patients with CKD and hyperkalemia was 24.9% versus 10.4% in patients with CKD without hyperkalemia. The allowed costs in patients with CKD and hyperkalemia in the Medicare and commercially insured cohorts were more than twice those in patients with CKD without hyperkalemia. Inpatient care accounted for >50% of costs in patients with CKD and hyperkalemia. Conclusion Hyperkalemia is associated with substantial clinical and economic burden among US commercially insured and Medicare populations. PMID:28794824

A retrospective, longitudinal study examined changes in participation in fitness-related activities and hospital claims over 5 years amongst members of an incentivized health promotion program offered by a private health insurer. A 3-year retrospective observational analysis measuring gym visits and participation in documented fitness-related activities, probability of hospital admission, and associated costs of admission. A South African private health plan, Discovery Health and the Vitality health promotion program. 304,054 adult members of the Discovery medical plan, 192,467 of whom registered for the health promotion program and 111,587 members who were not on the program. Members were incentivised for fitness-related activities on the basis of the frequency of gym visits. Changes in electronically documented gym visits and registered participation in fitness-related activities over 3 years and measures of association between changes in participation (years 1-3) and subsequent probability and costs of hospital admission (years 4-5). Hospital admissions and associated costs are based on claims extracted from the health insurer database. The probability of a claim modeled by using linear logistic regression and costs of claims examined by using general linear models. Propensity scores were estimated and included age, gender, registration for chronic disease benefits, plan type, and the presence of a claim during the transition period, and these were used as covariates in the final model. There was a significant decrease in the prevalence of inactive members (76% to 68%) over 5 years. Members who remained highly active (years 1-3) had a lower probability (p < .05) of hospital admission in years 4 to 5 (20.7%) compared with those who remained inactive (22.2%). The odds of admission were 13% lower for two additional gym visits per week (odds ratio, .87; 95% confidence interval [CI], .801-.949). We observed an increase in fitness-related activities over time amongst members of this incentive-based health promotion program, which was associated with a lower probability of hospital admission and lower hospital costs in the subsequent 2 years.

Competing cues: Older adults rely on knowledge in the face of fluency.
Brashier, Nadia M; Umanath, Sharda; Cabeza, Roberto; Marsh, Elizabeth J
2017-06-01
Consumers regularly encounter repeated false claims in political and marketing campaigns, but very little empirical work addresses their impact among older adults. Repeated statements feel easier to process, and thus more truthful, than new ones (i.e., illusory truth). When judging truth, older adults' accumulated general knowledge may offset this perception of fluency. In two experiments, participants read statements that contradicted information stored in memory; a post-experimental knowledge check confirmed what individual participants knew. Unlike young adults, older adults exhibited illusory truth only when they lacked knowledge about claims. This interaction between knowledge and fluency extends dual-process theories of aging.

Objectives Electronic nicotine delivery systems (ENDS), or e-cigarettes, are heavily marketed online. The purpose of our study was to perform a systematic identification and evaluation of claims made within ENDS retailer and manufacturer websites, and the legal status of such claims. Methods We employed a systematic search protocol with popular search engines using 6 terms: (1) e-cigarettes; (2) e-cigs; (3) e-juice; (4) e-liquid; (5) e-hookah; and (6) vape pen. We analyzed English-language websites where ENDS are sold for implicit and explicit health-related claims. A legal analysis determined whether such claims are permissible under the US Food and Drug Administration’s regulations. Results The vast majority of ENDS manufacturer (N = 78) and retailer (N = 32) websites made at least one health-related claim (77% and 65%, respectively). Modified risk claims and secondhand smoke-related claims were most prevalent, with an average of 2 claims per site. Conclusions Health-related claims are plentiful within ENDS manufacturer and retailer websites. Results demonstrate that these sites focus on potential benefits while minimizing or eliminating information about possible harmful effects of ENDS. These claims are subject to the current regulatory authority by the FDA, and pose a risk of misinforming consumers. PMID:27446984

Based on a literature search, there are limited data on the economic burden of systemic lupus erythematosus (SLE), particularly in patients with lupus nephritis. The objective of this study was to compare health care resource utilization and direct medical care costs over a period of 12 months in patients with a history of SLE with or without nephritis. Patients aged >or=18 years with >or=1 claim for an immunosuppressive/disease-modifying antirheumatic drug, antimalarial agent, NSAID/cyclooxygenase-2 inhibitor, or other SLE-related treatment (eg, opioid and combination analgesic, antianxiety agent, antihyperlipidemic agent, antihypertensive agent, bisphosphonate, vitamin D) dated between January 1, 2007, and December 31, 2007, were identified using a nationally representative, US commercial insurance claims database. The date of the first dispensation of the treatment represented the index date. Patients were required to have >or=2 claims containing a diagnosis of SLE during a 6-month preindex period through 3 months postindex and to have continuous health plan enrollment for 6 months before and 12 months after the index date. Patients with >or=1 claim containing a diagnosis of nephritis during the preindex period were identified. Health care resource utilization and direct medical care cost data were assessed over a period of 12 months; paid amounts were used as a proxy for costs and were expressed in year-2008 US dollars. A total of 15,590 patients with SLE were identified (13,828 women, 1762 men; mean age, 48 years); 1068 (6.9%) had a history of nephritis. The mean age of patients with SLE without nephritis was significantly greater compared with the group with nephritis (47.9 vs 46.5 years, respectively; P < 0.001), and a greater proportion of this group were women (89.0% vs 84.7%; P < 0.001). Over a period of 12 months, 30.3% of patients with nephritis were hospitalized compared with 13.6% of those without nephritis (P < 0.001); the mean lengths of hospital stays were 16.52 and 9.69 days (P < 0.001) in patients with and without nephritis, respectively. Patients with nephritis also underwent more outpatient laboratory tests (mean, 64.42 vs 30.96; P < 0.001) and had a significantly higher mean number of intravenous infusions (mean, 1.7 vs 1.1; P < 0.001), and total 12-month follow-up costs were significantly greater in patients with nephritis compared with those without nephritis (mean, $30,652 vs $12,029; P < 0.001). Costs associated with inpatient and outpatient care were 252% and 146% higher in patients with SLE with nephritis, respectively. Outpatient costs were associated with approximately half of the total costs in patients with or without nephritis; pharmacy costs accounted for 20% of the total costs in patients with SLE and nephritis and 27% of total costs among those without nephritis. Significantly higher costs also were found in patients with nephritis when only SLE-related costs were assessed and after differences in patient characteristics and comorbidities were adjusted through multivariate analyses (all, P < 0.05). The present data analysis found that patients with SLE with nephritis consumed significantly more health care resources, with >2.5-fold the costs, compared with those without nephritis. The majority (84%) of added costs were attributable to inpatient hospitalizations and outpatient services, and 16% were attributable to pharmacy services. Copyright 2009 Excerpta Medica Inc.

Video game training does not enhance cognitive ability: A comprehensive meta-analytic investigation.
Sala, Giovanni; Tatlidil, K Semir; Gobet, Fernand
2018-02-01
As a result of considerable potential scientific and societal implications, the possibility of enhancing cognitive ability by training has been one of the most influential topics of cognitive psychology in the last two decades. However, substantial research into the psychology of expertise and a recent series of meta-analytic reviews have suggested that various types of cognitive training (e.g., working memory training) benefit performance only in the trained tasks. The lack of skill generalization from one domain to different ones-that is, far transfer-has been documented in various fields of research such as working memory training, music, brain training, and chess. Video game training is another activity that has been claimed by many researchers to foster a broad range of cognitive abilities such as visual processing, attention, spatial ability, and cognitive control. We tested these claims with three random-effects meta-analytic models. The first meta-analysis (k = 310) examined the correlation between video game skill and cognitive ability. The second meta-analysis (k = 315) dealt with the differences between video game players and nonplayers in cognitive ability. The third meta-analysis (k = 359) investigated the effects of video game training on participants' cognitive ability. Small or null overall effect sizes were found in all three models. These outcomes show that overall cognitive ability and video game skill are only weakly related. Importantly, we found no evidence of a causal relationship between playing video games and enhanced cognitive ability. Video game training thus represents no exception to the general difficulty of obtaining far transfer. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

A minimally invasive endoscopic treatment that utilizes radio-frequency energy (RFE) has received increased attention as an appropriate middle-ground approach in the treatment of refractory gastroesophageal reflux disease (GERD) and as an alternative to complicated and invasive surgical procedures. The objective of this study was to develop a longitudinal budget impact analysis from the payer perspective to estimate the direct medical costs of treatment for the refractory GERD patient population and to estimate the budgetary impact of further extending the RFE treatment option to other target populations. A retrospective analysis of claims designed to assess the longitudinal costs and budget impact on payer expenditures associated with managing and treating GERD surgically (Nissen fundoplication [NF]), endoscopically (RFE), or medically was performed. Both Medicare and commercially insured claims databases were interrogated for such population-level analyses. At current adoption rates (less than 1% of procedures), RFE demonstrated overall cost savings ranging from 7.3% to 50.5% in the 12-month time period following the index procedure (inclusive of procedure costs) when compared to medical management and fundoplication across the commercial and Medicare patient populations. Increasing the total number of RFE procedures to 2% of total cases performed generated per-member, per-month (PMPM) savings of $0.28 in the Medicare population and $0.37 in the commercially insured population. Further increases yielded higher PMPM savings. Adding to the clinical importance of RFE in filling the gap between medical and surgical management, this economic analysis demonstrates to payers that the adoption of RFE can create notable savings to their plans when compared to surgery or medical management.

Anticonvulsant medications are commonly used for off-label indications. However, managed care organizations can restrict utilization of medication to indicated uses only. To evaluate the pattern of off-label use of second-generation anticonvulsants after implementing a formulary change. We did a retrospective analysis of an administrative pharmacy claims database for a managed care plan with more than 1 million members continuously enrolled during 2004-2005. The study evaluated off-label use and explored pharmacy utilization patterns (by physician specialty, region, plan type, age, sex, copayment) across the study population following the formulary change. A total of 10,185 patients had at least 1 pharmacy claim (total of 137,638 claims) for a second-generation anticonvulsant during the study period. Most members were female (68%), and 4.9% were <18 years old. A total of 3986 of 4698 patients (84.8%) and 4600 of 5487 patients (83.8%) had anticonvulsants prescribed for off-label use in 2004 and 2005, respectively (P = .162). The off-label usage pattern varied for individual anticonvulsants in 2004 and 2005 (P <.050), which may have been because of the change to nonpreferred coverage. Primary care physicians accounted for 41.3% of the prescribing of second-generation anticonvulsants for off-label uses, followed by neurologists (9.4%), psychiatrists (2.8%), and other (46.5%). The coverage change resulted in cost savings for the plan of $0.16 per member per month. The off-label usage pattern varied for individual anticonvulsants in 2004 and 2005. Future considerations for controlling off-label use may include requiring prior authorization and provider education.

The objective was to expand on prior work by developing and validating a new algorithm to identify multiple myeloma (MM) patients in administrative claims. Two files were constructed to select MM cases from MarketScan Oncology Electronic Medical Records (EMR) and controls from the MarketScan Primary Care EMR during January 1, 2000-March 31, 2014. Patients were linked to MarketScan claims databases, and files were merged. Eligible cases were age ≥18, had a diagnosis and visit for MM in the Oncology EMR, and were continuously enrolled in claims for ≥90 days preceding and ≥30 days after diagnosis. Controls were age ≥18, had ≥12 months of overlap in claims enrollment (observation period) in the Primary Care EMR and ≥1 claim with an ICD-9-CM diagnosis code of MM (203.0×) during that time. Controls were excluded if they had chemotherapy; stem cell transplant; or text documentation of MM in the EMR during the observation period. A split sample was used to develop and validate algorithms. A maximum of 180 days prior to and following each MM diagnosis was used to identify events in the diagnostic process. Of 20 algorithms explored, the baseline algorithm of 2 MM diagnoses and the 3 best performing were validated. Values for sensitivity, specificity, and positive predictive value (PPV) were calculated. Three claims-based algorithms were validated with ~10% improvement in PPV (87-94%) over prior work (81%) and the baseline algorithm (76%) and can be considered for future research. Consistent with prior work, it was found that MM diagnoses before and after tests were needed.

This study aimed to assess the nutritional quality of food products marketed at children, with and without nutrient claims, using two different approaches. Analyses were performed based on a data set with food composition and labelling data from every packaged food marketed at children sold in a major Brazilian supermarket (n=535). Foods were classified as 'healthier' and 'less healthy' according to the UK/Ofcom nutrient profile model and to the NOVA classification based on the level of food processing. Pearson's χ 2 test was used to compare proportions between models. Agreement was assessed using Cohen's κ-statistic (P<0.05). The NOVA model was stricter than the UK/Ofcom model, classifying more products as 'less healthy' (91.4%) compared with the nutrient profile-based model (75.0%; P<0.001). Agreement between models was 79.4% (k=0.30), because 72.9% (n=390) of products were categorised as 'less healthy' by both models, and 6.5% (n=35) as 'healthier'. Half of the food products marketed at children from the database (270; 50.5%) bore nutrient claims. From these products with nutrient claims, 95.9% (92.8-98.0) were classified as 'less healthy' by the NOVA model, whereas this percentage was 74.1% (68.4-79.2) according to the UK/Ofcom model (P<0.05). The high number of foods with low nutritional quality being marketed at children via product packaging and nutrient claims should be of concern to policy makers wanting to improve children's diets and to tackle childhood obesity. The implementation of nutritional quality criteria to ensure that foods targeted at children should be eligible to bear nutrient claims on their labels could avoid a situation where claims mask the overall nutritional status of a food.

Objective To determine the incidence and impact of recurrent workplace injury and disease over the period 1995–2008. Design Population-based cohort study using data from the state workers’ compensation system database. Setting State of Victoria, Australia. Participants A total of 448 868 workers with an accepted workers’ compensation claim between 1 January 1995 and 31 December 2008 were included into this study. Of them, 135 349 had at least one subsequent claim accepted for a recurrent injury or disease during this period. Main outcome measures Incidence of initial and recurrent injury and disease claims and time lost from work for initial and recurrent injury and disease. Results Over the study period, 448 868 workers lodged 972 281 claims for discrete occurrences of work-related injury or disease. 53.4% of these claims were for recurrent injury or disease. On average, the rates of initial claims dropped by 5.6%, 95% CI (−5.8% to −5.7%) per annum, while the rates of recurrent injuries decreased by 4.1%, 95% CI (−4.2% to −0.4%). In total, workplace injury and disease resulted in 188 978 years of loss in full-time work, with 104 556 of them being for the recurrent injury. Conclusions Recurrent work-related injury and disease is associated with a substantial social and economic impact. There is an opportunity to reduce the social, health and economic burden of workplace injury by enacting secondary prevention programmes targeted at workers who have incurred an initial occupational injury or disease.

Duloxetine is approved to treat diabetic peripheral neuropathic pain (DPNP) in the US. The study objective was to examine the predictors of duloxetine compliance, and its association with healthcare costs among DPNP patients. The study used administrative claims databases to identify non-depressed DPNP patients with a duloxetine prescription dispensed between October 1, 2004 and December 31, 2006. Two cohorts of patients were constructed based on compliance to duloxetine therapy over 1-year follow-up with high compliance defined as a medication possession ratio (MPR) > or =0.80. All-cause, diabetes-, and DPNP-related healthcare costs during 1-year follow-up were estimated. Logistic regressions were performed to examine how average daily dose (ADD) of duloxetine and other factors may influence compliance. Multivariate regressions were estimated to examine the association between compliance and healthcare costs. The study included 1,380 commercially insured (mean age 55 years) and 974 patients with employer-sponsored Medicare supplemental insurance (mean age 75 years). In both populations, patients with an ADD >30 mg were more likely to be compliant with the therapy compared with those with an ADD of < or =30 mg (odds ratio ranged 1.79-3.38, all p<0.05). Controlling for differences in demographics, clinical and economic characteristics, commercially insured low duloxetine compliance patients had greater all-cause ($5,334, p<0.05) and diabetes-related healthcare costs ($3,414, p<0.05) than high-compliance patients, with the biggest difference from inpatient costs (all-cause: $7,508; diabetes-related: $3,785, all p<0.05). Similar trends were found in the Medicare supplemental insured population; however, differences in all-cause healthcare costs were not significant. DPNP patients with a higher ADD of duloxetine over a 1-year follow-up period were more compliant with the therapy. Duloxetine patients with high compliance were also associated with lower healthcare costs. Due to the use of a retrospective cohort design on administrative claims database, limitations of this analysis include a lack of formal diagnostic testing of patients, and inability to infer causality or measure factors such as DPNP severity that are not captured in such database.

Social media analysis has rarely been applied to the study of specific questions in outcomes research. The aim was to test the applicability of social media analysis to outcomes research using automated listening combined with filtering and analysis of data by specialists. After validation, the process was applied to the study of patterns of treatment switching in multiple sclerosis (MS). A comprehensive listening and analysis process was developed that blended automated listening with filtering and analysis of data by life sciences-qualified analysts and physicians. The population was patients with MS from the United States. Data sources were Facebook, Twitter, blogs, and online forums. Sources were searched for mention of specific oral, injectable, and intravenous (IV) infusion treatments. The representativeness of the social media population was validated by comparison with community survey data and with data from three large US administrative claims databases: MarketScan, PharMetrics Plus, and Department of Defense. A total of 10,260 data points were sampled for manual review: 3025 from Twitter, 3771 from Facebook, 2773 from Internet forums, and 691 from blogs. The demographics of the social media population were similar to those reported from community surveys and claims databases. Mean age was 39 (SD 11) years and 14.56% (326/2239) of the population was older than 50 years. Women, patients aged 30 to 49 years, and those diagnosed for more than 10 years were represented by more data points than other patients were. Women also accounted for a large majority (82.6%, 819/991) of reported switches. Two-fifths of switching patients had lived with their disease for more than 10 years since diagnosis. Most reported switches (55.05%, 927/1684) were from injectable to oral drugs with switches from IV therapies to orals the second largest switch (15.38%, 259/1684). Switches to oral drugs accounted for more than 80% (927/1114) of the switches away from injectable therapies. Four reasons accounted for more than 90% of all switches: severe side effects, lack of efficacy, physicians' advice, and greater ease of use. Side effects were the main reason for switches to oral or to injectable therapies and search for greater efficacy was the most important factor in switches to IV therapies. Cost of medication was the reason for switching in less than 0.5% of patients. Social intelligence can be applied to outcomes research with power to analyze MS patients' personal experiences of treatments and to chart the most common reasons for switching between therapies.

Disputed claims and delayed payments are among the principal sources of provider and vendor dissatisfaction with managed care payment systems. Timely and accurate claims-payment systems are essential to ensure provider and vendor satisfaction, fiscal stability, and regulatory compliance. A focused analysis of conditions contributing to late payment of claims can disclose problems in provider, vendor, or payer operational and billing procedures, contracting processes, information systems, or human resources management. Resolution of these conditions equips claims-processing staff with tools to resolve problem claims promptly, thereby lowering costs.

There has been a steady increase in cases reported to the Norwegian System of Patient Injury Compensation (NPE). We wished to look into what might characterise those cases of central and peripheral nerve blockade for anaesthesia that led to compensation claims. Cases with codes for central and peripheral blockade within the field of anaesthesiology were retrieved from the NPE database for the period 2001 – 14. The cases were evaluated on the basis of variables including sex, age, type of anaesthesia, diagnosis, type of injury, site of injury, damages received, and written descriptions of treatment and injury. The expert reports were anonymised and reviewed in detail. A total of 339 patient compensation claims relating to nerve blockade were identified, of which 149 concerned spinal anaesthesia, 142 epidural anaesthesia, 21 combined spinal and epidural anaesthesia and 27 peripheral nerve blockade. The group consisted of 236 women and 103 men, and the average age was 46 years. The 339 cases comprised 0.8 % of all cases reported to the NPE in this period. A total of 107 claims resulted in compensation. Eighty-two million Norwegian kroner were paid out in total. Peripheral and central nerve blockade accounts for only a small proportion of cases handled by the NPE. Only one in three applicants had their claim upheld, but when claims were upheld, the injuries were often severe and led to substantial pay-outs.

Health insurance claims (ie, receipts) record patient health care treatments and expenses and, although created for the health care payment system, are potentially useful for research. Combining different types of receipts generated for the same patient would dramatically increase the utility of these receipts. However, technical problems, including standardization of disease names and classifications, and anonymous linkage of individual receipts, must be addressed. In collaboration with health insurance societies, all information from receipts (inpatient, outpatient, and pharmacy) was collected. To standardize disease names and classifications, we developed a computer-aided post-entry standardization method using a disease name dictionary based on International Classification of Diseases (ICD)-10 classifications. We also developed an anonymous linkage system by using an encryption code generated from a combination of hash values and stream ciphers. Using different sets of the original data (data set 1: insurance certificate number, name, and sex; data set 2: insurance certificate number, date of birth, and relationship status), we compared the percentage of successful record matches obtained by using data set 1 to generate key codes with the percentage obtained when both data sets were used. The dictionary's automatic conversion of disease names successfully standardized 98.1% of approximately 2 million new receipts entered into the database. The percentage of anonymous matches was higher for the combined data sets (98.0%) than for data set 1 (88.5%). The use of standardized disease classifications and anonymous record linkage substantially contributed to the construction of a large, chronologically organized database of receipts. This database is expected to aid in epidemiologic and health services research using receipt information.

To identify relevant factors involved in obstetrics and gynecology (OG) professional liability claims to help archive better management of risks. Analysis of 885 OG claims opened between 1986 and 2010, with the identification of the most common events leading to a claim, the economical and juridical characteristics of the claims, as well as the relevant trends over the study period. Most claims related to obstetrics. Labor, delivery and its complications accounted for 33.1% of the claims; 12.77% related specifically to cesarean. Oncological diseases, fetus death during labor and delivery, neurologically impaired infant and histerectomy-related problems were the most frequently claimed events. Most cases ended up without an indemnity payment and 37.7% of closed files were solved by an out-of-court procedure. Average payment was higher for the obstetric procedures than for those concerning gynecology cases. The proportion of claims relating to obstetrics increased during the study period, as well as the average payment. OG is at high-risk for malpractice claims, but compensation awards are not frequent. However, particular events, such as retained foreign objects, tubal ligation, ultrasound diagnosis or neurologically impaired newborns, deserve special attention regarding medico-legal issues.

Osteoporosis therapies: evidence from health-care databases and observational population studies.
Silverman, Stuart L
2010-11-01
Osteoporosis is a well-recognized disease with severe consequences if left untreated. Randomized controlled trials are the most rigorous method for determining the efficacy and safety of therapies. Nevertheless, randomized controlled trials underrepresent the real-world patient population and are costly in both time and money. Modern technology has enabled researchers to use information gathered from large health-care or medical-claims databases to assess the practical utilization of available therapies in appropriate patients. Observational database studies lack randomization but, if carefully designed and successfully completed, can provide valuable information that complements results obtained from randomized controlled trials and extends our knowledge to real-world clinical patients. Randomized controlled trials comparing fracture outcomes among osteoporosis therapies are difficult to perform. In this regard, large observational database studies could be useful in identifying clinically important differences among therapeutic options. Database studies can also provide important information with regard to osteoporosis prevalence, health economics, and compliance and persistence with treatment. This article describes the strengths and limitations of both randomized controlled trials and observational database studies, discusses considerations for observational study design, and reviews a wealth of information generated by database studies in the field of osteoporosis.

The aim of this analysis was to implement a claims-based algorithm to estimate biologic cost per effectively treated patient for biologics approved for moderate to severe rheumatoid arthritis (RA). This retrospective analysis included commercially insured adults (aged 18-63 years) with RA in a commercial database, who initiated biologic treatment with abatacept, adalimumab, etanercept, golimumab, or infliximab between 2007 and 2010. The algorithm defined effectiveness as having all of the following: high adherence, no biologic dose increase, no biologic switching, no new nonbiologic disease-modifying antirheumatic drug, no increased or new oral glucocorticoid use, and no more than 1 glucocorticoid injection. For each biologic, cost per effectively treated patient was defined as total drug and administration costs (from allowed amounts on claims), divided by the number of patients categorized as effectively treated. Of 15,351 patients, 12,018 (78.3%) were women, and the mean (SD) age was 49.7 (9.6) years. The algorithm categorized treatment as effective in the first year for 30% (1899/6374) of etanercept, 30% (1396/4661) of adalimumab, 20% (560/2765) of infliximab, 27% (361/1338) of abatacept, and 29% (62/213) of golimumab treated patients. The 1-year biologic cost per effectively treated patient, as defined by the algorithm, was nominally lower for subcutaneously injected biologics than for infused biologics. The 1-year biologic cost per effectively treated patient, as defined by the algorithm, was lowest for etanercept ($49,952), followed by golimumab ($50,189), adalimumab ($52,858), abatacept ($71,866), and infliximab ($104,333). Algorithm-defined effectiveness was similar for biologics other than infliximab. The 1-year biologic cost per effectively treated patient, as defined by the algorithm, was nominally lower for subcutaneously injected biologics than for infused biologics.

The objective of this study was to evaluate medical comorbidity patterns in patients with a narcolepsy diagnosis in the United States. This was a retrospective medical claims data analysis. Truven Health Analytics MarketScan® Research Databases were accessed to identify individuals ≥18 years of age with ≥1 diagnosis code for narcolepsy (International Classification of Diseases (ICD)-9, 347.0, 347.00, 347.01, 347.1, 347.10, or 347.11) continuously insured between 2006 and 2010, and controls without narcolepsy matched 5:1 on age, gender, region, and payer. Narcolepsy and control subjects were compared for frequency of comorbid conditions, identified by the appearance of >1 diagnosis code(s) mapped to a Clinical Classification System (CCS) level 1 category any time during the study period, and on specific subcategories, including recognized narcolepsy comorbidities of obstructive sleep apnea (OSA) and depression. The final study group included 9312 subjects with narcolepsy and 46,559 controls (each group: average age, 46.1 years; 59% female). As compared with controls, patients with narcolepsy showed a statistically significant excess prevalence in all the CCS multilevel categories, the only exceptions being conditions originating in the perinatal period and pregnancy/childbirth complications. The greatest excess prevalence in the narcolepsy cohort was seen for mental illness (31.1% excess prevalence; odds ratio (OR) 3.8, 95% confidence interval (CI) 3.6, 4.0), followed by diseases of the digestive system (21.4% excess prevalence; OR 2.7, 95% CI 2.5, 2.8) and nervous system/sense organs (excluding narcolepsy; 20.7% excess prevalence; OR 3.7, 95% CI 3.4, 3.9). In this claims analysis, a narcolepsy diagnosis was associated with a wide range of comorbid medical illness claims, at significantly higher rates than matched controls. Copyright © 2016.

The purpose of this evaluation was to study the relationship of nurse care coordination (NCC) to the costs of Medicare and Medicaid in a community-based care program called Missouri Care Options (MCO). A retrospective cohort design was used comparing 57 MCO clients with NCC to 80 MCO clients without NCC. Total cost was measured using Medicare and Medicaid claims databases. Fixed effects analysis was used to estimate the relationship of the NCC intervention to costs. Controlling for high resource use on admission, monthly Medicare costs were lower ($686) in the 12 months of NCC intervention (p =.04) while Medicaid costs were higher ($203; p=.03) for the NCC group when compared to the costs of MCO group.

The use of health and nutrition content claims in infant formula advertising is restricted by many governments in response to WHO policies and WHA resolutions. The purpose of this study was to determine whether such prohibited claims could be observed in Australian websites that advertise infant formula products. A comprehensive internet search was conducted to identify websites that advertise infant formula available for purchase in Australia. Content analysis was used to identify prohibited claims. The coding frame was closely aligned with the provisions of the Australian and New Zealand Food Standard Code, which prohibits these claims. The outcome measures were the presence of health claims, nutrition content claims, or references to the nutritional content of human milk. Web pages advertising 25 unique infant formula products available for purchase in Australia were identified. Every advertisement (100%) contained at least one health claim. Eighteen (72%) also contained at least one nutrition content claim. Three web pages (12%) advertising brands associated with infant formula products referenced the nutritional content of human milk. All of these claims appear in spite of national regulations prohibiting them indicating a failure of monitoring and/or enforcement. Where countries have enacted instruments to prohibit health and other claims in infant formula advertising, the marketing of infant formula must be actively monitored to be effective. © 2016 John Wiley & Sons Ltd.

The Canadian Study of Health and Aging (CSHA) was a cohort study that included 528 Nova Scotian community-dwelling participants. Linkage of CSHA and provincial Medical Services Insurance (MSI) data enabled examination of health care utilization in this subsample. This article discusses methodological and ethical issues of database linkage and explores variation in the use of health services by demographic variables and health status. Utilization over 24 months following baseline was extracted from MSI's physician claims, hospital discharge abstracts, and Pharmacare claims databases. Twenty-nine subjects refused consent for access to their MSI file; health card numbers for three others could not be retrieved. A significant difference in healthcare use by age and self-rated health was revealed. Linkage of population-based data with provincial administrative health care databases has the potential to guide health care planning and resource allocation. This process must include steps to ensure protection of confidentiality. Standard practices for linkage consent and routine follow-up should be adopted. The Canadian Study of Health and Aging (CSHA) began in 1991-92 to explore dementia, frailty, and adverse health outcomes (Canadian Study of Health and Aging Working Group, 1994). The original CSHA proposal included linkage to provincial administrative health care databases by the individual CSHA study centers to enhance information on health care utilization and outcomes of study participants. In Nova Scotia, the Medical Services Insurance (MSI) administration, which drew the sampling frame for the original CSHA, did not retain the list of corresponding health card numbers. Furthermore, consent for this access was not asked of participants at the time of the first interview. The objectives of this study reported here were to examine the feasibility and ethical considerations of linking data from the CSHA to MSI utilization data, and to explore variation in health services use by demographic and health status characteristics in the Nova Scotia community cohort.

To analyze the preoperative factors associated with the need for secondary surgery following primary urethroplasty. This study utilized a subset of the National Health Insurance Research Database, which includes the data on all paid medical benefit claims from 1997 to 2007, for 1 million beneficiaries in 2005. We analyzed the claims data for all patients with hypospadias who had undergone primary urethroplasty. The characteristics of the patients, surgeons, and hospitals associated with surgical outcomes were analyzed to investigate possible associations with the need for secondary surgery. Among 52,705 live male newborn babies, 218 were diagnosed with hypospadias, of whom 89 received repair surgery. A total of 75 (84.3%) male newborn babies received single hypospadias surgery, and 14 (15.7%) underwent more than two surgical procedures. Univariate analysis demonstrated that the type of hypospadias and the surgeon caseload volume were significantly associated with the need for additional hypospadias surgery (p = 0.02 and p = 0.03, respectively). In multivariate analysis, the type of hypospadias (distal vs. proximal, odds ratio, 0.25; p = 0.03) and the surgeon caseload volume (high vs. low, odds ratio, 0.04; p = 0.05) were significantly correlated with secondary operation. The type of hypospadias and the surgeon caseload volume were significantly associated with the need for secondary hypospadias surgery. The findings of this study provide important information on the outcomes of hypospadias repair for parents and specialists. Copyright © 2017. Published by Elsevier Taiwan.

Observational healthcare data offer the potential to identify adverse drug reactions that may be missed by spontaneous reporting. The self-controlled cohort analysis within the Temporal Pattern Discovery framework compares the observed-to-expected ratio of medical outcomes during post-exposure surveillance periods with those during a set of distinct pre-exposure control periods in the same patients. It utilizes an external control group to account for systematic differences between the different time periods, thus combining within- and between-patient confounder adjustment in a single measure. To evaluate the performance of the calibrated self-controlled cohort analysis within Temporal Pattern Discovery as a tool for risk identification in observational healthcare data. Different implementations of the calibrated self-controlled cohort analysis were applied to 399 drug-outcome pairs (165 positive and 234 negative test cases across 4 health outcomes of interest) in 5 real observational databases (four with administrative claims and one with electronic health records). Performance was evaluated on real data through sensitivity/specificity, the area under receiver operator characteristics curve (AUC), and bias. The calibrated self-controlled cohort analysis achieved good predictive accuracy across the outcomes and databases under study. The optimal design based on this reference set uses a 360 days surveillance period and a single control period 180 days prior to new prescriptions. It achieved an average AUC of 0.75 and AUC >0.70 in all but one scenario. A design with three separate control periods performed better for the electronic health records database and for acute renal failure across all data sets. The estimates for negative test cases were generally unbiased, but a minor negative bias of up to 0.2 on the RR-scale was observed with the configurations using multiple control periods, for acute liver injury and upper gastrointestinal bleeding. The calibrated self-controlled cohort analysis within Temporal Pattern Discovery shows promise as a tool for risk identification; it performs well at discriminating positive from negative test cases. The optimal parameter configuration may vary with the data set and medical outcome of interest.

Dissemination of misleading drug information through social media can be detrimental to the health of the public. This study, carried out in Bahrain, evaluated the truthfulness of 22 social media claims about drugs (72.7%), dietary supplements (22.7%), and toxic bisphenol-A (4.5%). They circulated on WhatsApp platform, as case studies. We categorized claims as objectively true, false, or potentially misleading. The content analysis revealed that "potentially misleading" claims were the most frequent messages (59.1%). They tend to exaggerate the efficacy or safety without sufficient evidence to substantiate claims. False claims (27.3%) were likely due to unfair competition or deception. Overall, 13.6% of the messages were objectively true claims that could withstand regulatory scrutiny. Majority of the drug-related messages on social media were potentially misleading or false claims that lacked credible evidence to support them. In the public interest, regulatory authorities should monitor such information disseminated via social media platforms.

In Sweden, patient malpractice claims are handled administratively and compensated if an independent physician review confirms patient injury resulting from medical error. Full access to all malpractice claims and hospital discharge data for the country provided a unique opportunity to assess the validity of patient claims as indicators of medical error and patient injury. To determine: (1) the percentage of patient malpractice claims validated by independent physician review, (2) actual malpractice claims rates (claims frequency / clinical volume) and (3) differences between Swedish and other national malpractice claims rates. DESIGN, SETTING AND MATERIAL: Swedish national malpractice claims and hospital discharge data were combined, and malpractice claims rates were determined by county, hospital, hospital department, surgical procedure, patient age and sex and compared with published studies on medical error and malpractice. From 1997 to 2004, there were 23 364 inpatient malpractice claims filed by Swedish patients treated at hospitals reporting 11 514 798 discharges. The overall claims rate, 0.20%, was stable over the period of study and was similar to that found in other tort and administrative compensation systems. Over this 8-year period, 49.5% (range 47.0-52.6%) of filed claims were judged valid and eligible for compensation. Claims rates varied significantly across hospitals; surgical specialties accounted for 46% of discharges, but 88% of claims. There were also large differences in claims rates for procedures. Patient-generated malpractice claims, as collected in the Swedish malpractice insurance system and adjusted for clinical volumes, have a high validity, as assessed by standardised physician review, and provide unique new information on malpractice risks, preventable medical errors and patient injuries. Systematic collection and analysis of patient-generated quality of care complaints should be encouraged, regardless of the malpractice compensation system in use.

Health technology assessment (HTA) has been continuously used for value-based healthcare decisions over the last decade. Healthcare databases represent an important source of information for HTA, which has seen a surge in use in Western countries. Although HTA agencies have been established in Asia-Pacific region, application and understanding of healthcare databases for HTA is rather limited. Thus, we reviewed existing databases to assess their potential for HTA in Thailand where HTA has been used officially and Japan where HTA is going to be officially introduced. Existing healthcare databases in Thailand and Japan were compiled and reviewed. Databases' characteristics e.g. name of database, host, scope/objective, time/sample size, design, data collection method, population/sample, and variables were described. Databases were assessed for its potential HTA use in terms of safety/efficacy/effectiveness, social/ethical, organization/professional, economic, and epidemiological domains. Request route for each database was also provided. Forty databases- 20 from Thailand and 20 from Japan-were included. These comprised of national censuses, surveys, registries, administrative data, and claimed databases. All databases were potentially used for epidemiological studies. In addition, data on mortality, morbidity, disability, adverse events, quality of life, service/technology utilization, length of stay, and economics were also found in some databases. However, access to patient-level data was limited since information about the databases was not available on public sources. Our findings have shown that existing databases provided valuable information for HTA research with limitation on accessibility. Mutual dialogue on healthcare database development and usage for HTA among Asia-Pacific region is needed.
Neonatal hypoglycaemia: learning from claims.

Neonatal hypoglycaemia is a potential cause of neonatal morbidity, and on rare but tragic occasions causes long-term neurodevelopmental harm with consequent emotional and practical costs for the family. The organisational cost to the NHS includes the cost of successful litigation claims. The purpose of the review was to identify themes that could alert clinicians to common pitfalls and thus improve patient safety. The NHS Litigation Authority (NHS LA) Claims Management System was reviewed to identify and review 30 claims for injury secondary to neonatal hypoglycaemia, which were notified to the NHS LA between 2002 and 2011. NHS LA. Anonymised documentation relating to 30 neonates for whom claims were made relating to neonatal hypoglycaemia. Dates of birth were between 1995 and 2010. Review of documentation held on the NHS LA database. Identifiable risk factors for hypoglycaemia, presenting clinical signs, possible deficits in care, financial costs of litigation. All claims related to babies of at least 36 weeks' gestation. The most common risk factor for hypoglycaemia was low birth weight or borderline low birth weight, and the most common reported presenting sign was abnormal feeding behaviour. A number of likely deficits in care were reported, all of which were avoidable. In this 10-year reporting period, there were 25 claims for which damages were paid, with a total financial cost of claims to the NHS of £162 166 677. Acknowledging that these are likely to be the most rare but most seriously affected cases, the clinical themes arising from these cases should be used for further development of training and guidance to reduce harm and redivert NHS funds from litigation to direct care.

This study performs premium analysis for copula models with regression marginals. For illustration purpose, the copula models are fitted to the Malaysian motor insurance claims data. In this study, we consider copula models from Archimedean and Elliptical families, and marginal distributions of Gamma and Inverse Gaussian regression models. The simulated results from independent model, which is obtained from fitting regression models separately to each claim category, and dependent model, which is obtained from fitting copula models to all claim categories, are compared. The results show that the dependent model using Frank copula is the best model since the risk premiums estimated under this model are closely approximate to the actual claims experience relative to the other copula models.
A current appraisal of health- and nutrition-related claims in magazine food advertisements.

2013-01-01
This article reports a content analysis of health- and nutrition-related claims used in food advertisements in popular women's and men's magazines. The authors analyzed 734 food ads and 100 magazine issues. Their research shows that nutrient content claims (i.e., ones that focus on a specific nutrient component such as "low in fat") are the most predominantly used, followed by general nutrition claims, structure/function claims, and healthy claims. The least used category is health claims, in which the advertised food is linked to reduced risk of a disease or health problem. The use of health- and nutrition-related claims differs across different food groups and types of magazines.

The chronic nature of human immunodeficiency virus (HIV) infection requires lifelong highly active antiretroviral (ARV) therapy (HAART) to continuously suppress HIV-1 viral replication, thus reducing morbidity and mortality. HAART is restricted by complex dosing, drug-drug interactions (DDIs) and toxicities. To determine the prevalence of possible DDIs between ARV drugs in different age groups in a section of the private primary health care sector in South Africa. A quantitative, retrospective drug utilization review was performed on 47 085 ARV prescriptions claimed through a national medicine claims database during 2006. Possible DDIs identified were classified according to a clinical significance rating as described by Tatro [Drug Interaction Facts 2005. St Louis, MO: Facts and Comparisons (2005)]. The total number of patients who received prescriptions that were claimed through the medicine claims database was 275 424, of whom 25.11% were males, 28.28% were females and the gender of 46.61% patients was unknown. Of the total number of patients, 3.27% were HIV patients of which an average of 5.23 +/- 3.86 ARV prescriptions (n = 47 085) per patient were claimed for representing 4.73% of the total number of prescriptions claimed during the study period (N = 993 804). HIV patients received an average of 2.36 +/- 0.61 ARVs per prescription. Only 4.95% of the prescriptions had one ARV medicine item, 56.04% two, 37.10% three, 1.75% four and <1% had more than four. Of 960 DDIs identified, 1.88% were for patients < or =6 years, 4.27% for patients >6 years and < or =12 years, 0.63% for patients >12 and < or =19 years, 32.40% for patients <19 years and < or =40 years, 60.21% for patients <40 years and < or =60 years and 0.63% for patients >60 years with patients <40 years and < or =60 years having the highest number of DDIs and patients older than 60 years the lowest. The majority of DDIs between the ARVs presented in significance levels 2 and 4. The most important interactions were between: indinavir (IDV) and ritonavir (n = 199); efavirenz (EFV) and lopinavir/ritonavir (n = 65) and EFV and IDV (n = 60) all interacting at level 2. The importance of using drug utilization study as an identification tool to provide insight into the prescribing and utilization patterns of ARV drugs, to provide optimal therapy for patients infected with HIV is emphasized.

Objective Assess algorithms for linking patients across de-identified databases without compromising confidentiality. Data Sources/Study Setting Hospital discharges from 11 Mayo Clinic hospitals during January 2008–September 2012 (assessment and validation data). Minnesota death certificates and hospital discharges from 2009 to 2012 for entire state (application data). Study Design Cross-sectional assessment of sensitivity and positive predictive value (PPV) for four linking algorithms tested by identifying readmissions and posthospital mortality on the assessment data with application to statewide data. Data Collection/Extraction Methods De-identified claims included patient gender, birthdate, and zip code. Assessment records were matched with institutional sources containing unique identifiers and the last four digits of Social Security number (SSNL4). Principal Findings Gender, birthdate, and five-digit zip code identified readmissions with a sensitivity of 98.0 percent and a PPV of 97.7 percent and identified postdischarge mortality with 84.4 percent sensitivity and 98.9 percent PPV. Inclusion of SSNL4 produced nearly perfect identification of readmissions and deaths. When applied statewide, regions bordering states with unavailable hospital discharge data had lower rates. Conclusion Addition of SSNL4 to administrative data, accompanied by appropriate data use and data release policies, can enable trusted repositories to link data with nearly perfect accuracy without compromising patient confidentiality. States maintaining centralized de-identified databases should add SSNL4 to data specifications. PMID:26073819

This study examined the extent to which older adults identified in a statewide abuse hotline registry utilized behavioral health services. This is important as mental health issues have been identified as a high priority for filling gaps in services for victims of mistreatment. We compared Medicaid and Medicare claims data for two groups of older adults: those using health services and identified within a statewide abuse hotline information system and those claimants not identified within the hotline database. Behavioral health service use was greater among those identified in the abuse hotline database. The penetration rate (percentage of service users out of all enrollees) for Medicaid behavioral health service claims was more than twice that of other service users, with costs of services about 30% greater. Analyses of Medicare data revealed that the penetration rate for those in the hotline data was almost 6 times greater at approximately twice the cost compared to other service users. The results provide evidence for previous assumptions that mistreated individuals experience a higher rate of behavioral health disorders. As mental health screening by adult protective services is rarely conducted, the results suggest the need to train investigators and other service providers to screen older adults for behavioral health and substance-abuse issues as well as physical signs of abuse. Further research on the relationship of abuse to behavioral health might focus on collection of additional data involving more specific victim-related characteristics and comparisons of cases of mistreatment versus self-neglect.

The large majority of caesarean sections in the UK are now carried out under neuraxial anaesthesia. Although this technique is widely accepted as being the safest option in most circumstances, the use of regional anaesthesia increases the risk of patients experiencing intra-operative discomfort or pain. Pain during operative obstetric delivery is the commonest successful negligence claim relating to regional anaesthesia against obstetric anaesthetists in the UK. In the following article, using a database of over 360 cases spanning 21 years, we break down and examine the recurrent components of medicolegal claims concerning pain during caesarean section and consider how anaesthetists might avoid litigation. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

Different structures and coding schemes may limit rapid evaluation of a large pool of potential drug safety signals using multiple longitudinal healthcare databases. To overcome this restriction, a semi-automated approach utilising common data model (CDM) and robust pharmacoepidemiologic methods was developed; however, its performance needed to be evaluated. Twenty-three established drug-safety associations from publications were reproduced in a healthcare claims database and four of these were also repeated in electronic health records. Concordance and discrepancy of pairwise estimates were assessed between the results derived from the publication and results from this approach. For all 27 pairs, an observed agreement between the published results and the results from the semi-automated approach was greater than 85% and Kappa coefficient was 0.61, 95% CI: 0.19-1.00. Ln(IRR) differed by less than 50% for 13/27 pairs, and the IRR varied less than 2-fold for 19/27 pairs. Reproducibility based on the intra-class correlation coefficient was 0.54. Most covariates (>90%) in the publications were available for inclusion in the models. Once the study populations and inclusion/exclusion criteria were obtained from the literature, the analysis was able to be completed in 2-8 h. The semi-automated methodology using a CDM produced consistent risk estimates compared to the published findings for most selected drug-outcome associations, regardless of original study designs, databases, medications and outcomes. Further assessment of this approach is useful to understand its roles, strengths and limitations in rapidly evaluating safety signals.

For the last century, there has been a continuing debate about the nature of emotion. In the most recent offering in this scientific dialogue, Lench, Flores, and Bench (2011) reported a meta-analysis of emotion induction research and claimed support for the natural kind hypothesis that discrete emotions (e.g., happiness, sadness, anger, and anxiety) elicit specific changes in cognition, judgment, behavior, experience, and physiology. In this article, we point out that Lench et al. (2011) is not the final word on the emotion debate. First, we point out that Lench et al.'s findings do not support their claim that discrete emotions organize cognition, judgment, experience, and physiology because they did not demonstrate emotion-consistent and emotion-specific directional changes in these measurement domains. Second, we point out that Lench et al.'s findings are in fact consistent with the alternative (a psychological constructionist approach to emotion). We close by appealing for a construct validity approach to emotion research, which we hope will lead to greater consensus on the operationalization of the natural kind and psychological construction approaches, as well as the criteria required to finally resolve the emotion debate.

Inflammatory bowel disease (IBD) is a chronic disease of the gastrointestinal tract attributed to aberrant activity of the immune system. Increasing evidence suggests that patients with IBD are at an increased risk of inflammatory skin diseases (ISDs). We sought to clarify the association between IBD and ISDs using a nationwide health claims database maintained in Korea. We interrogated Korean health claim database data from 2009 to 2013. We enrolled all patients with IBD, and age- and sex-matched control subjects, and evaluated the risks of ISDs, including psoriasis, rosacea, and atopic dermatitis, and the risks of autoimmune skin diseases, including vitiligo and alopecia areata. We used multivariable logistic regression to this end. ISDs including rosacea, psoriasis, and atopic dermatitis were significantly associated with IBD, whereas the associations between IBD and autoimmune skin diseases including vitiligo and alopecia areata were less marked or nonexistent. Ulcerative colitis and Crohn's disease were both associated with ISDs. We were unable to distinguish phenotypes and severities of skin diseases. IBD was significantly associated with ISDs, but less so or not at all with autoimmune skin diseases. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

This study aimed to estimate and identify determinants of direct medical costs associated with rheumatoid arthritis (RA) in Turkey using nationwide real-world data. Using the Turkish National Health Insurance Database (2009-2011), RA patients (ages 18-99) were identified using International Classification of Disease Tenth Revision Clinical Modification (ICD-10-CM) codes. Patients were required to have two RA diagnoses at least 60 days apart and were grouped as prevalent and incident cases. The date of the first RA claim was identified for each patient and designated as the index date. Total healthcare costs were examined over the 12-month period following the index date. Descriptive and multivariate analyses are provided. Generalized linear models were used to calculate expected annual costs for incident and prevalent RA patients after controlling for age, gender, region, comorbid conditions and medication. A total of 2,613 patients met all inclusion criteria (693 incident; 1,920 prevalent patients). Prevalent patients were older, less likely to reside in the Marmara region, had higher comorbidity index scores and were more likely to use non-steroidal anti-inflammatory drugs, biologics and disease-modifying anti-rheumatic drugs relative to incident patients. Average direct annual costs were

Background Idiopathic inflammatory myopathies (IIMs) are a rare group of autoimmune syndromes characterized by chronic muscle inflammation and muscle weakness with no known cause. Little is known about their incidence and prevalence. This study reports the incidence and prevalence of IIMs among commercially insured and Medicare and Medicaid enrolled populations in the US. Methods We retrospectively examined medical claims with an IIM diagnosis (ICD-9-CM 710.3 [dermatomyositis (DM)], 710.4 [polymyositis (PM)], 728.81[interstitial myositis]) in the MarketScan® databases to identify age- and gender-adjusted annual IIM incidence and prevalence for 2004–2008. Sensitivity analysis was performed for evidence of a specialist visit (rheumatologist/ neurologist/dermatologist), systemic corticosteroid or immunosuppressant use, or muscle biopsy. Results We identified 2,990 incident patients between 2004 and 2008 (67% female, 17% Medicaid enrollees, 27% aged ≥65 years). Overall adjusted IIM incidence for 2004–2008 for commercial and Medicare supplemental groups combined were 4.27 cases (95% CI, 4.09-4.44) and for Medicaid, 5.23 (95% CI 4.74-5.72) per 100,000 person-years (py). Disease sub-type incidence rates per 100,000-py were 1.52 (95% CI 1.42-1.63) and 1.70 (1.42-1.97) for DM, 2.46 (2.33-2.59) and 3.53 (3.13-3.94) for PM, and 0.73 (0.66-0.81) and 0.78 (0.58-0.97) for interstitial myositis for the commercial/Medicare and Medicaid cohorts respectively. Annual incidence fluctuated over time with the base MarketScan populations. There were 7,155 prevalent patients, with annual prevalence ranging from 20.62 to 25.32 per 100,000 for commercial/Medicare (83% of prevalent cases) and from 15.35 to 32.74 for Medicaid. Conclusions We found higher IIM incidence than historically reported. Employer turnover, miscoding and misdiagnosing, care seeking behavior, and fluctuations in database membership over time can influence the results. Further studies are needed to confirm the incidence and prevalence of IIM. PMID:22703603

The objective of this study was to examine the relationship of work loss associated with gastro- the relationship of work loss associated with gastro- the relationship of work loss associated with gastro-esophageal reflux disease (GERD) and peptic ulcer disease (GERD) and peptic ulcer disease (PUD) in a large population of employed individuals in the United States (US) and quantify the individuals in the United States (US) and quantify the economic impact of these diseases to the employer. A proprietary database that contained work place absence, disability and workers' compensation data in addition to prescription drug and medical claims was used to answer the objectives. Employees with a medical claim with an ICD-9 code for GERD or PUD were identified from 1 January 1997 to 31 December 2000. A cohort of controls was identified for the same time period using the method of frequency matching on age, gender, industry type, occupational status, and employment status. Work absence rates and health care costs were compared between the groups after adjusting for demo graphic, and employment differences using analysis of covariance models. There were significantly lower (p < 0.05) prescription, and outpatient costs in the controls compared to the disease groups, although the eta-square values were very low. The mean work absence attributed to sick days was 2.8 (+/- 2.3) for controls, 3.4 (+/- 2.5) for GERD, 3.2 (+/- 2.6) for PUD, and 3.2 (+/- 2.3) days for GERD + PUD. For work loss, a significantly higher (p < 0.05) rate of adjusted all-cause absenteeism and sickness-related absenteeism were observed between the disease groups versus the controls. In particular, controls had an average of 1.2 to 1.6 days and 0.4 to 0.6 lower all-cause and sickness-related absenteeism compared to the disease groups. The incremental economic impact projected to a hypothetical employed population was estimated to be $3441 for GERD, $1374 for PUD, and $4803 for GERD + PUD per employee per year compared to employees without these diseases. Direct medical cost and work absence in employees with GERD, PUD and GERD + PUD represent a significant burden to employees and employers.

The objective of this retrospective analysis was to assess the correlation of comorbid depression and/or anxiety to patterns of treatment, healthcare utilization, and associated costs among diabetic peripheral neuropathic pain (DPNP) patients, employing a large US administrative claims database. Patients under age 65 with commercial insurance and patients aged 65 and older with employer-sponsored Medicare supplemental insurance were selected for the study if they had at least one diagnosis of DPNP in 2005. The first observed DPNP claim was considered the 'index date.' All individuals had a 12-month pre-index and 12-month follow-up period. For both populations, two subgroups were constructed for individuals with depression and/or anxiety (DPNP-DA cohort) or without these disorders (DPNP-only cohort). Patients' demographic characteristics, clinical characteristics, and medication use were compared over the pre-index period. Healthcare expenditures and resource utilization were measured for the post-index period. Two-part models were used to examine the impact of comorbid depression and/or anxiety on healthcare utilization and costs, controlling for demographic and clinical characteristics. The study identified 11,854 DPNP-only and 1512 DPNP-DA patients in the Medicare supplemental cohort, and 11,685 and 2728 in the commercially insured cohort. Compared to DPNP-only patients over the follow-up period, a significantly higher percentage of DPNP-DA patients were dispensed pain and DPNP-related medication. All components of healthcare utilization, except home healthcare visits and physician office visits, were more likely to be provided to DPNP-DA patients versus the DPNP-only cohort (all p < 0.01). Controlling for differences in demographic and clinical characteristics, DPNP-DA patients had significantly higher total costs than those of DPNP-only patients for Medicare ($9134, p < 0.01) and commercially insured patients ($11,085, p < 0.01). Due to the use of a retrospective administrative claims database, limitations of this study include the potential for selection bias between study cohorts, mis-identification of DPNP and/or depression, and inability to assess indirect costs as well as use and cost of over-the-counter medications. These findings indicate that the healthcare costs were significantly higher for DPNP patients comorbid with depression and/or anxiety relative to those without such disorders.

This is the first study of workers' compensation injuries and costs in Department of Defense workers that examined whether any demographic factors including age, sex, occupation, and nature of injury altered the risks or costs of an injury or illness over time. Department of Defense Workers' Compensation claims for period 2000 to 2008 were analyzed (n = 142,115) using Defense Portal Analysis and Defense Manpower Data Center to calculate injury rates and costs. Regression analysis was done using SPSS to examine the change in the risk of injury or illness over time from 2000 to 2008. The age group of 30 to 34 years had the lowest costs per claim and highest claims rate, 332 per 10,000. The age group of 65 to 70 years had the lowest claims rate of 188 per 10,000 but the highest costs per claim. Claims cost increased $69 for each 5-year group, and older workers had a threefold increase in costs per claim. Younger workers get hurt more often, but older workers tend to have more expensive claims.

Background Health technology assessment (HTA) has been continuously used for value-based healthcare decisions over the last decade. Healthcare databases represent an important source of information for HTA, which has seen a surge in use in Western countries. Although HTA agencies have been established in Asia-Pacific region, application and understanding of healthcare databases for HTA is rather limited. Thus, we reviewed existing databases to assess their potential for HTA in Thailand where HTA has been used officially and Japan where HTA is going to be officially introduced. Method Existing healthcare databases in Thailand and Japan were compiled and reviewed. Databases’ characteristics e.g. name of database, host, scope/objective, time/sample size, design, data collection method, population/sample, and variables were described. Databases were assessed for its potential HTA use in terms of safety/efficacy/effectiveness, social/ethical, organization/professional, economic, and epidemiological domains. Request route for each database was also provided. Results Forty databases– 20 from Thailand and 20 from Japan—were included. These comprised of national censuses, surveys, registries, administrative data, and claimed databases. All databases were potentially used for epidemiological studies. In addition, data on mortality, morbidity, disability, adverse events, quality of life, service/technology utilization, length of stay, and economics were also found in some databases. However, access to patient-level data was limited since information about the databases was not available on public sources. Conclusion Our findings have shown that existing databases provided valuable information for HTA research with limitation on accessibility. Mutual dialogue on healthcare database development and usage for HTA among Asia-Pacific region is needed. PMID:26560127
Feminism and psychology: critiques of methods and epistemology.
Eagly, Alice H; Riger, Stephanie
2014-10-01
Starting in the 1960s, many of the critiques of psychological science offered by feminist psychologists focused on its methods and epistemology. This article evaluates the current state of psychological science in relation to this feminist critique. The analysis relies on sources that include the PsycINFO database, the Publication Manual of the American Psychological Association (American Psychological Association, 2010), and popular psychology methods textbooks. After situating the feminist critique within the late-20th-century shift of science from positivism to postpositivism, the inquiry examines feminists' claims of androcentric bias in (a) the underrepresentation of women as researchers and research participants and (b) researchers' practices in comparing women and men and describing their research findings. In most of these matters, psychology manifests considerable change in directions advocated by feminists. However, change is less apparent in relation to some feminists' criticisms of psychology's reliance on laboratory experimentation and quantitative methods. In fact, the analyses documented the rarity in high-citation journals of qualitative research that does not include quantification. Finally, the analysis frames feminist methodological critiques by a consideration of feminist epistemologies that challenge psychology's dominant postpositivism. Scrutiny of methods textbooks and journal content suggests that within psychological science, especially as practiced in the United States, these alternative epistemologies have not yet gained substantial influence.

Self-ligating brackets (SLBs) are widely adopted in clinic owing to their claimed superiorities. Here, we collected and analysed all randomized controlled clinical trials (RCTs) comparing SLBs with conventional brackets (CBs) and thereby investigated whether SLBs can relieve discomfort or promote oral hygiene. Electronic databases including MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, World Health Organization International Clinical Trials Registry Platform, Chinese BioMedical Literature Database and the China National Knowledge Infrastructure were searched to find out RCTs comparing active or passive SLBs with CBs. Two reviewers extracted the data and assessed risks of bias independently. Any disagreement between them was resolved through discussion with a third reviewer. Meta-analysis was conducted on Review Manager 5.3. A total of 12 RCTs with 575 participants were included, and eight of the trials were synthesized quantitatively. Two trials were assessed as low risk of bias, whereas others as unclear risk of bias. Passive SLBs and CBs are not significantly different in plaque control. SLBs and CBs are not significantly different in discomfort reduction at any of four time points (4 h, 24 h, 3 days and 7 days). Clinical evidences from existing RCTs suggest that SLBs do not outperform CBs in reliving discomfort or promoting oral health in clinic. © 2016 John Wiley & Sons A/S.

To evaluate the extent to which balance in unmeasured characteristics of patients with type 2 diabetes (T2DM) was achieved in claims data, by comparing against more detailed information from linked electronic health records (EHR) data. Within a large US commercial insurance database and using a cohort design, we identified patients with T2DM initiating linagliptin or a comparator agent within class (ie, another dipeptidyl peptidase-4 inhibitor) or outside class (ie, pioglitazone or a sulphonylurea) between May 2011 and December 2012. We focused on comparators used at a similar stage of diabetes to linagliptin. For each comparison, 1:1 propensity score (PS) matching was used to balance >100 baseline claims-based characteristics, including proxies of diabetes severity and duration. Additional clinical data from EHR were available for a subset of patients. We assessed representativeness of the claims-EHR-linked subset, evaluated the balance of claims- and EHR-based covariates before and after PS-matching via standardized differences (SDs), and quantified the potential bias associated with observed imbalances. From a claims-based study population of 166 613 patients with T2DM, 7219 (4.3%) patients were linked to their EHR data. Claims-based characteristics in the EHR-linked and EHR-unlinked patients were similar (SD < 0.1), confirming the representativeness of the EHR-linked subset. The balance of claims-based and EHR-based patient characteristics appeared to be reasonable before PS-matching and generally improved in the PS-matched population, to be SD < 0.1 for most patient characteristics and SD < 0.2 for select laboratory results and body mass index categories, which was not large enough to cause meaningful confounding. In the context of pharmacoepidemiological research on diabetes therapy, choosing appropriate comparison groups paired with a new-user design and 1:1 PS matching on many proxies of diabetes severity and duration improves balance in covariates typically unmeasured in administrative claims datasets, to the extent that residual confounding is unlikely. © 2017 John Wiley & Sons Ltd.

Recent advances in data collection during routine health care in the form of Electronic Health Records (EHR), medical device data (e.g., infusion pump informatics, physiological monitoring data, and insurance claims data, among others, as well as biological and experimental data, have created tremendous opportunities for biological discoveries for clinical application. However, even with all the advancement in technologies and their promises for discoveries, very few research findings have been translated to clinical knowledge, or more importantly, to clinical practice. In this paper, we identify and present the initial work addressing the relevant challenges in three broad categories: data, accessibility, and translation. These issues are discussed in the context of a widely used detailed database from an intensive care unit, Medical Information Mart for Intensive Care (MIMIC III) database.
Scientific relevance of Swiss property insurance data on flood risks and losses

The databases of Swiss flood insurance companies build a valuable but to date rarely used source of information for flood risk research. Detailed insights into the Swiss flood insurance system are crucial to evaluate the potential of the different databases for scientific analysis. Even though the flood insurance system modalities are mainly regulated on cantonal level there are some common principles that apply throughout Switzerland. First of all coverage against floods (and other particular natural hazards) is an integral part of every fire insurance policy for buildings or contents in Switzerland. This coupling of insurance as well as the statutory obligation to insure buildings in most of the cantons and movables in some of the cantons lead to a very high penetration. Second, in case of damage, the reinstatement costs (value as new) are compensated and third there are no (or little) deductible and co-pay. Thus the different datasets of the flood insurance companies would allow a very comprehensive data analysis. Moreover, insurance companies not only store electronically data about losses (typically date, amount of claims payment, cause of damage, identity of the insured object or policyholder) but also about insured objects. For insured objects the (insured) value and the details on the policy and its holder are the main feature to record. On buildings the insurance companies usually computerize additional information such as location, volume, year of construction or purpose of use. For the 19 (of total 26) cantons with a cantonal monopoly insurer the data of these insurance establishments have the additional value to represent (almost) the entire building stock of the respective canton. However, scientists face a wide range of the opportunities and challenges when using insurance data for flood research. The origin of flood insurance data implies that they are not generated for research but for business management. The presentation will highlighted pro and cons as well as challenges of different aspects such as data compilation and geocoding, spatial and temporal coverage of data, data generation regarding the purpose of efficient and correct management of policies and claims, data protection regulations, differences in the use of technical key terms between risk research and insurance business to answer the questions how relevant and useful are the flood insurance data for flood risk analysis. An outlook will be provided how to encourage the (data) exchange between flood risk business and research.
Framing and Claiming: How Information-Framing Affects Expected Social Security Claiming Behavior.
Brown, Jeffrey R; Kapteyn, Arie; Mitchell, Olivia S
2016-03-01
This paper provides evidence that Social Security benefit claiming decisions are strongly affected by framing and are thus inconsistent with expected utility theory. Using a randomized experiment that controls for both observable and unobservable differences across individuals, we find that the use of a "breakeven analysis" encourages early claiming. Respondents are more likely to delay when later claiming is framed as a gain, and the claiming age is anchored at older ages. Additionally, the financially less literate, individuals with credit card debt, and those with lower earnings are more influenced by framing than others.

Flavonoids are frequently used as dietary supplements in the absence of research evidence regarding health benefits or toxicity. Furthermore, ingested doses could far exceed those received from diet in the course of normal living. Some flavonoids exhibit binding to estrogen receptors (ERs) with consequential vigilance by regulatory authorities at the U.S. EPA and FDA. Regulatory authorities must consider both beneficial claims and potential adverse effects, warranting the increases in research that has spanned almost two decades. Here, we report pathway enrichment of 14 targets from the Comparative Toxicogenomics Database (CTD) and the Herbal Ingredients’ Targets (HIT) database for 22 flavonoids that bind ERs. The selected flavonoids are confirmed ER binders from our earlier studies, and were here found in mainly involved in three types of biological processes, ER regulation, estrogen metabolism and synthesis, and apoptosis. Besides cancers, we conjecture that the flavonoids may affect several diseases via apoptosis pathways. Diseases such as amyotrophic lateral sclerosis, viral myocarditis and non-alcoholic fatty liver disease could be implicated. More generally, apoptosis processes may be importantly evolved biological functions of flavonoids that bind ERs and high dose ingestion of those flavonoids could adversely disrupt the cellular apoptosis process.

Due to its phenomenal growth requiring neither nitrogen fertilizer nor arable land and its biomass composition, the mosquito fern Azolla is a candidate crop to yield food, fuels and chemicals sustainably. To advance Azolla domestication, we research its dissemination, storage and transcriptome. Methods for dissemination, cross-fertilization and cryopreservation of the symbiosis Azolla filiculoides-Nostoc azollae are tested based on the fern spores. To study molecular processes in Azolla including spore induction, a database of 37 649 unigenes from RNAseq of microsporocarps, megasporocarps and sporophytes was assembled, then validated. Spores obtained year-round germinated in vitro within 26 d. In vitro fertilization rates reached 25%. Cryopreservation permitted storage for at least 7 months. The unigene database entirely covered central metabolism and to a large degree covered cellular processes and regulatory networks. Analysis of genes engaged in transition to sexual reproduction revealed a FLOWERING LOCUS T-like protein in ferns with special features induced in sporulating Azolla fronds. Although domestication of a fern-cyanobacteria symbiosis may seem a daunting task, we conclude that the time is ripe and that results generated will serve to more widely access biochemicals in fern biomass for a biobased economy.

Association of major depression and diabetes in medically indigent Puerto Rican adults.
Disdier-Flores, Orville M
2010-03-01
Studies have found that major depression and diabetes mellitus are strongly associated. The main goal of this study was to evaluate the association between major depression and diabetes in a large medically indigent population of Puerto Rican adults living on the island. A secondary database analysis through a cross-sectional design was used for this study. Participants were selected from the Puerto Rico Commonwealth Health Plan database, beneficiaries of the public health sector. Adult's subjects with at least one claim during 2002 were included. The final sample consisted of 1,026,625 adult insured. The International Classification of Diseases (ICD-9) was used for disease classifications. The prevalence of diabetes was 14.6% in subjects with major depression and 9.7% for those without major depression (POR 1.59, p < 0.001). The strength of this association remained after adjusting for obesity and sex. Prevalence of diabetes appears to be significantly higher in Puerto Rican adults with major depression compared to those without this psychiatric disorder. Longitudinal prospective studies and randomized controlled trials are needed to shed light on the temporal or causal relationship and to test whether effective prevention and treatment can reduce the risk of developing diabetes.

The objective of this study was to develop and validate coding algorithms for epilepsy using ICD-coded inpatient claims, physician claims, and emergency room (ER) visits. 720/2049 charts from 2003 and 1533/3252 charts from 2006 were randomly selected for review from 13 neurologists' practices as the "gold standard" for diagnosis. Epilepsy status in each chart was determined by 2 trained physicians. The optimal algorithm to identify epilepsy cases was developed by linking the reviewed charts with three administrative databases (ICD 9 and 10 data from 2000 to 2008) including hospital discharges, ER visits and physician claims in a Canadian health region. Accepting chart review data as the gold standard, we calculated sensitivity, specificity, positive, and negative predictive value for each ICD-9 and ICD-10 administrative data algorithm (case definitions). Of 18 algorithms assessed, the most accurate algorithm to identify epilepsy cases was "2 physician claims or 1 hospitalization in 2 years coded" (ICD-9 345 or G40/G41) and the most sensitive algorithm was "1 physician clam or 1 hospitalization or 1 ER visit in 2 years." Accurate and sensitive case definitions are available for research requiring the identification of epilepsy cases in administrative health data. Copyright © 2012 Elsevier B.V. All rights reserved.
Administrative database research has unique characteristics that can risk biased results.
van Walraven, Carl; Austin, Peter
2012-02-01
The provision of health care frequently creates digitized data--such as physician service claims, medication prescription records, and hospitalization abstracts--that can be used to conduct studies termed "administrative database research." While most guidelines for assessing the validity of observational studies apply to administrative database research, the unique data source and analytical opportunities for these studies create risks that can make them uninterpretable or bias their results. Nonsystematic review. The risks of uninterpretable or biased results can be minimized by; providing a robust description of the data tables used, focusing on both why and how they were created; measuring and reporting the accuracy of diagnostic and procedural codes used; distinguishing between clinical significance and statistical significance; properly accounting for any time-dependent nature of variables; and analyzing clustered data properly to explore its influence on study outcomes. This article reviewed these five issues as they pertain to administrative database research to help maximize the utility of these studies for both readers and writers. Copyright © 2012 Elsevier Inc.

The objective of this analysis was to compare adherence at 6 months and 12 months across levothyroxine formulations for patients with hypothyroidism. This retrospective analysis utilized insurance claims data from a commercially insured population from January 1, 2000 through March 31, 2016. Patients were included if they were diagnosed with hypothyroidism and initiated treatment with generic levothyroxine, Levoxyl, Synthroid, Unithroid, or Tirosint. Patients were excluded if they were younger than age 18, were diagnosed with thyroid cancer, received a prescription for liothyronine, or did not have continuous insurance coverage over the study period. Adherence, defined by the proportion of days covered (PDC) ≥ 80%, was examined using multivariable analyses for both 6 and 12 months post-initiation on therapy Results: The study identified 580,331 patients who fit the study criteria. At 6 months, 40.3% of patients were found to be non-adherent, while 51.9% were non-adherent at 12 months. Synthroid was associated with significantly higher adherence compared to all other levothyroxine formulations at both 6 and 12 months. Compared to generic levothyroxine, the likelihood of being adherent at 12 months was highest for Synthroid (OR = 1.44; 95% CI = 1.43-1.46), followed by Levoxyl (OR = 1.20 95% CI = 1.17-1.23). Tirosint and Unithroid were associated with significantly lower adherence at 12 months compared to generic levothyroxine (OR = 0.65; 95% CI = 0.57-0.75 and OR = 0.79; 95% CI = 0.71-0.89, respectively). This large, retrospective real-world study demonstrated that adherence to levothyroxine remains a concern among patients with hypothyroidism, and that differences in adherence may exist across levothyroxine formulations.

Complex regional pain syndrome is a challenging condition that includes a broad spectrum of sensory, autonomic, and motor features predominantly in extremities recovering from a trauma. Few large-scale studies have addressed occurrence of and factors associated with complex regional pain syndrome (CRPS) following orthopedic treatment. The present study aimed to identify factors associated with post-treatment development of CRPS. Using the Danish Patient Compensation Association's database, we identified 647 patients claiming post-treatment CRPS between 1992 and 2015. Age, gender, initial diagnosis, treatment, and amount of compensation were extracted. Multivariate logistic regressions were performed to identify variables associated with approval of the claim. For carpal tunnel syndrome (CTS) patients, we registered whether symptoms were bilateral or unilateral and if neurophysiology prior to treatment was pathologic. The following ratios were found: women:men was 4:1, primary diagnosis to the upper limb:lower limb was 2.5:1, and surgical:nonsurgical treatment was 3:1. Mean age was 47.5 ± 13.7 years, and no intergender difference was detected. Antebrachial fracture (23%) and CTS (9%) were the most common primary conditions. Surgical treatment was associated with approval of the claim (odds ratio 3.5, 95% confidence interval 2.3 to 5.3; P < 0.001). Half of CTS patients had normal neurophysiology prior to surgery; among patients with unilateral symptoms, 71.4% had normal neurophysiology. Female gender, surgical treatment, and treatment to the upper limb were risk factors. Elective surgery accounted for a large number of post-treatment CRPS patients. In CTS patients developing CRPS, normal neurophysiological examination findings were common, and it could be suspected that these patients were suffering from an pre-clinical stage of CRPS, not CTS. © 2017 World Institute of Pain.

The objective of the study is to examine the epidemiologic data of closed malpractice medical claims against emergency departments (EDs) in Taiwanese civil courts and to identify high-risk diseases. We conducted a retrospective study and reviewed the verdicts from the national database of the Taiwan judicial system that pertained to EDs. Between 2003 and 2012, a total of 63 closed medical claims were included. Seven cases (11.1%) resulted in an indemnity payment, 55.6% of the cases were closed in the district court, but appeals were made to the supreme court in 12 cases (19.1%). The mean incident-to-litigation closure time was 57.7 ± 26.8 months. Of the cases with indemnity paid, 5 cases (71.4%) were deceased, and 2 cases (28.6%) were gravely injured. All cases with indemnity paid were determined to be negligent by a medical appraisal. The gravely injured patients had more indemnity paid than deceased patients ($299800 ± 37000 vs $68700 ± 29300). The most common medical conditions involved were infectious diseases (27.0%), central nervous system bleeding (15.9%), and trauma cases (12.7%). It was also found that 71.4% of the allegations forming the basis of the lawsuit were diagnosis related. Emergency physicians (EPs) in Taiwan have similar medico-legal risk as American EPs, with an annual risk of being sued of 0.63%. Almost 90% of EPs win their cases but spend 58 months in litigation, and the mean indemnity payment was $134738. Cases with indemnity paid were mostly categorized as having diagnosis errors, with the leading cause of error as failure to order an appropriate diagnostic test. Copyright © 2014 Elsevier Inc.

Impact of Frontloading of Skilled Nursing Visits on the Incidence of 30-day Hospital Readmission
O'Connor, Melissa; Hanlon, Alexandra; Bowles, Kathryn H.
2014-01-01
Hospitalization among older adults receiving skilled home health services continues to be prevalent. Frontloading of skilled nursing visits, defined as providing 60% of the planned skilled nursing visits within the first two weeks of home health episode, is one way home health agencies have attempted to reduce the need for readmission among this chronically ill population. This was a retrospective observational study using data from five Medicare-owned, national assessment and claim databases from 2009. An independent randomized sample of 4,500 Medicare-reimbursed home health beneficiaries was included in the analyses. Propensity score analysis was used to reduce known confounding among covariates prior to the application of logistic analysis. Although whether skilled nursing visits were frontloaded or not was not a significant predictor of 30-day hospital readmission (p=0.977), additional research is needed to refine frontloading and determine the type of patients who are most likely to benefit from it.

Although clinical theories of posttraumatic stress disorder (PTSD) claim that in this condition trauma memories tend to be disorganized and fragmented, this has been disputed by some autobiographical memory researchers, such as Rubin, Berntsen, and their colleagues (e.g., Rubin et al., 2016). In this article I review the evidence for and against the fragmentation hypothesis and identify important sources of methodological variability between the studies. This analysis suggests that fragmentation and disorganization are associated with differences in the type of narrative (specifically, with detailed rather than general narratives) and in the focus of the analysis (specifically, with a local focus on sections of text concerned with the worst moments of the trauma rather than with a global focus on the text as a whole). The implication is that apparently discrepant data and discrepant views can be accommodated within a more comprehensive formulation of memory impairment in PTSD.

Images on food and dietary supplement packaging might lead people to infer (appropriately or inappropriately) certain health benefits of those products. Research on this issue largely involves direct questions, which could (a) elicit inferences that would not be made unprompted, and (b) fail to capture inferences made implicitly. Using a novel memory-based method, in the present research, we explored whether packaging imagery elicits health inferences without prompting, and the extent to which these inferences are made implicitly. In 3 experiments, participants saw fictional product packages accompanied by written claims. Some packages contained an image that implied a health-related function (e.g., a brain), and some contained no image. Participants studied these packages and claims, and subsequently their memory for seen and unseen claims were tested. When a health image was featured on a package, participants often subsequently recognized health claims that-despite being implied by the image-were not truly presented. In Experiment 2, these recognition errors persisted despite an explicit warning against treating the images as informative. In Experiment 3, these findings were replicated in a large consumer sample from 5 European countries, and with a cued-recall test. These findings confirm that images can act as health claims, by leading people to infer health benefits without prompting. These inferences appear often to be implicit, and could therefore be highly pervasive. The data underscore the importance of regulating imagery on product packaging; memory-based methods represent innovative ways to measure how leading (or misleading) specific images can be.

Patient safety is a major concern worldwide, but particularly high rates of adverse events are reported in the surgery setting. Angiology and vascular surgery is of special interest due to the complexity of the pathologies involved and the esthetic component of some of its procedures. In this study we identified the most frequent factors that apply to vascular surgery claims to determine areas of special risk in vascular surgery, with an aim to improve patient safety. We performed a retrospective and descriptive study of the claims pertaining to vascular surgery from the database of the Service of Professional Liability (SRP) of the Official College of Physicians of Barcelona. The time frame of data collection was from 1986 to 2009. We analyzed both the clinical and legal characteristics of the cases. Of the total of 6952 registered claims during the 23-year period, 91 (1.3%) were related to the practice of vascular surgery. Of these, 53.8% were related to venous pathology and 46.1% to arterial pathology. Neurologic damage was the main motive for claims (15.3%), followed by thromboembolic disease (14.2%), burns as a result of cosmetic treatment (12%), and amputation (10.9%). The neurologic damage in relation to vein pathology registered the greatest proportion of cases with professional liability (30.8%), followed by burns (19.2%), forgotten gauze (11.5%), and amputations (11.5%). Angiology and vascular surgery does not seem to be a specialty with a high risk for claims, but complications, such as thromboembolic disease and neurologic damage after varicose vein intervention, do occur and deserve special attention so improvements can be made to patient safety.

Optimization of prescribing in older adults is needed. The STOPP criteria provide a systematic way of identifying potentially inappropriate prescribing in this population. Previous research indicates poor concordance between benzodiazepine prescribing and STOPP. To determine the extent and predictors of benzodiazepine and zopiclone (BZD-Z) pharmacy dispensations in older adults with a history of a recent fall, in concordance with STOPP. Prescription claims data from the Nova Scotia Seniors' Phamacare Program were linked with fall-related injury data from the CIHI Discharge Abstract Database. Adults aged ≥ 66 years making a claim for a BZD-Z in the 100 days prior to fall-related hospitalization were identified. Their BZD-Z claims in the 100 days following discharge were also identified. Descriptive statistics, trend tests and logistical regression modelling were performed to examine predictors for continued use of BZD-Z post-fall. Over 5 years, from a pool of 8,271 older adults discharged following a fall-related hospitalization, 1,789 (21.6%) had made a claim for a BZD-Z in the 100 days prior to admission. Of these, 82% were women. Younger age and female sex were predictors of continuing BZD-Z dispensations post-fall. In the 100 days following discharge, 74.2% (n=1327) made a claim for at least one BZD-Z. BZD-Z use continued in 74% of patients following discharge from a fall-related hospitalization, representing limited concordance with the STOPP criterion. Such hospitalizations and follow-up care present an opportunity to address an ongoing modifiable risk factor.

Biometric databases form an essential tool in the fight against international terrorism, organised crime and fraud. Various government and law enforcement agencies have their own biometric databases consisting of combination of fingerprints, Iris codes, face images/videos and speech records for an increasing number of persons. In many cases personal data linked to biometric records are incomplete and/or inaccurate. Besides, biometric data in different databases for the same individual may be recorded with different personal details. Following the recent terrorist atrocities, law enforcing agencies collaborate more than before and have greater reliance on database sharing. In such an environment, reliable biometric-based identification must not only determine who you are but also who else you are. In this paper we propose a compact content-based video signature and indexing scheme that can facilitate retrieval of multiple records in face biometric databases that belong to the same person even if their associated personal data are inconsistent. We shall assess the performance of our system using a benchmark audio visual face biometric database that has multiple videos for each subject but with different identity claims. We shall demonstrate that retrieval of relatively small number of videos that are nearest, in terms of the proposed index, to any video in the database results in significant proportion of that individual biometric data.

Health management is becoming increasingly complex, given a range of care options and the need to balance costs and quality. The ability to measure and understand drivers of costs is critical for healthcare organizations to effectively manage their patient populations. Healthcare decision makers can leverage real-world evidence to explore the value of disease-management interventions in shifting total cost trends. To develop a real-world, evidence-based estimator that examines the impact of disease-management interventions on the total cost of care (TCoC) for a patient population with nonvalvular atrial fibrillation (NVAF). Data were collected from a patient-level real-world evidence data set that uses the IMS PharMetrics Health Plan Claims Database. Pharmacy and medical claims for patients meeting the inclusion or exclusion criteria were combined in longitudinal cohorts with a 180-day preindex and 360-day follow-up period. Descriptive statistics, such as mean and median patient costs and event rates, were derived from a real-world evidence analysis and were used to populate the base-case estimates within the TCoC estimator, an exploratory economic model that was designed to estimate the potential impact of several disease-management activities on the TCoC for a patient population with NVAF. Using Microsoft Excel, the estimator is designed to compare current direct costs of medical care to projected costs by varying assumptions on the impact of disease-management activities and applying the associated changes in cost trends to the affected populations. Disease-management levers are derived from literature-based concepts affecting costs along the NVAF disease continuum. The use of the estimator supports analyses across 4 US geographic regions, age, cost types, and care settings during 1 year. All patients included in the study were continuously enrolled in their health plan (within the IMS PharMetrics Health Plan Claims Database) between July 1, 2010, and June 30, 2012. Patients were included in the final analytic file and were indexed based on (1) the service date of the first claim within the selection window (December 28, 2010-July 11, 2011) with a diagnosis of NVAF, or (2) the service date of the second claim for an NVAF medication of interest during the same selection window. The model estimates the current trends in national benchmark data for a hypothetical health plan with 1 million covered lives. The annual total direct healthcare costs (allowable and patient out-of-pocket costs) of managing patients with NVAF in this hypothetical plan are estimated at $184,981,245 ($25,754 per patient, for 7183 patients). A potential 25% improvement from the base-case disease burden and disease management could translate into TCoC savings from reducing the excess costs related to hypertension (-5.3%) and supporting the use of an appropriate antithrombotic treatment that prevents ischemic stroke (-0.7%) and reduces bleeding events (-0.1%). The use of the TCoC estimator supports population health management by providing real-world evidence benchmark data on NVAF disease burden and by quantifying the potential value of disease-management activities in shifting cost trends.

Background Health management is becoming increasingly complex, given a range of care options and the need to balance costs and quality. The ability to measure and understand drivers of costs is critical for healthcare organizations to effectively manage their patient populations. Healthcare decision makers can leverage real-world evidence to explore the value of disease-management interventions in shifting total cost trends. Objective To develop a real-world, evidence-based estimator that examines the impact of disease-management interventions on the total cost of care (TCoC) for a patient population with nonvalvular atrial fibrillation (NVAF). Methods Data were collected from a patient-level real-world evidence data set that uses the IMS PharMetrics Health Plan Claims Database. Pharmacy and medical claims for patients meeting the inclusion or exclusion criteria were combined in longitudinal cohorts with a 180-day preindex and 360-day follow-up period. Descriptive statistics, such as mean and median patient costs and event rates, were derived from a real-world evidence analysis and were used to populate the base-case estimates within the TCoC estimator, an exploratory economic model that was designed to estimate the potential impact of several disease-management activities on the TCoC for a patient population with NVAF. Using Microsoft Excel, the estimator is designed to compare current direct costs of medical care to projected costs by varying assumptions on the impact of disease-management activities and applying the associated changes in cost trends to the affected populations. Disease-management levers are derived from literature-based concepts affecting costs along the NVAF disease continuum. The use of the estimator supports analyses across 4 US geographic regions, age, cost types, and care settings during 1 year. Results All patients included in the study were continuously enrolled in their health plan (within the IMS PharMetrics Health Plan Claims Database) between July 1, 2010, and June 30, 2012. Patients were included in the final analytic file and were indexed based on (1) the service date of the first claim within the selection window (December 28, 2010-July 11, 2011) with a diagnosis of NVAF, or (2) the service date of the second claim for an NVAF medication of interest during the same selection window. The model estimates the current trends in national benchmark data for a hypothetical health plan with 1 million covered lives. The annual total direct healthcare costs (allowable and patient out-of-pocket costs) of managing patients with NVAF in this hypothetical plan are estimated at $184,981,245 ($25,754 per patient, for 7183 patients). A potential 25% improvement from the base-case disease burden and disease management could translate into TCoC savings from reducing the excess costs related to hypertension (−5.3%) and supporting the use of an appropriate antithrombotic treatment that prevents ischemic stroke (−0.7%) and reduces bleeding events (−0.1%). Conclusions The use of the TCoC estimator supports population health management by providing real-world evidence benchmark data on NVAF disease burden and by quantifying the potential value of disease-management activities in shifting cost trends.

Acromegaly is a chronic disorder characterized by excess growth hormone secretion and elevated insulin-like growth factor-1 levels most often caused by a pituitary adenoma. Clinical presentation of the disease includes coarsening of the facial features, soft-tissue swelling of the hands and feet, and overgrowth of the frontal skull and protrusion of the jaw, as well as joint symptoms. Acromegaly is associated with several comorbidities, including diabetes, cardiovascular disease, and arthropathy, which, if left untreated, can lead to early mortality. Surgery to remove the adenoma is the first-line treatment for many patients, but more than 50% of patients will require additional pharmacologic or radiation therapy. To (a) determine the clinical and economic burden of illness among patients with acromegaly using administrative claims data from a large, commercially insured population in the United States and (b) estimate the most frequent acromegaly-related comorbidities and health care resource utilization and costs among these patients. This retrospective, observational cohort study used administrative claims data from the HealthCore Integrated Research Database, containing a geographically diverse spectrum of longitudinal claims data from the largest database of commercially insured patients in the United States. Patients were aged ≥ 20 years and fulfilled ≥ 1 of the following criteria during the intake period (March 31, 2008-July 31, 2012): ≥ 2 independent diagnostic codes for acromegaly, ≥ 1 acromegaly diagnosis code and ≥ 1 acromegaly-related procedure code, or ≥ 1 acromegaly diagnosis code and ≥ 1 medical claim for acromegaly-related therapy. The index date was defined as the date of the first medical claim for acromegaly within the intake period. Assessed outcomes included prevalence of acromegaly diagnosis and incidence of new acromegaly diagnoses during the study period (January 1, 2008-July 31, 2013), acromegaly-related comorbidities, and pharmacotherapy use. Because 2008 and 2012 data were incomplete, incidence rates were only reported for 2009, 2010, and 2011. Total and acromegaly-related health care resource utilization and annual health care costs were analyzed during a 12-month post-index observational period. In total, 757 patients with acromegaly met the selection criteria for this study, with a mean age of 49.3 years (53.6% female). The total prevalence of acromegaly was 41.7 cases per million. Acromegaly incidence was 15.0, 13.3, and 9.5 cases per million in 2009, 2010, and 2011, respectively. The top 5 acromegaly-related comorbidities were hypertension, diabetes, hypothyroidism, arthropathy/arthralgia/synovitis, and sleep apnea. During the study period, 51% of patients (n = 385) used acromegaly-related pharmacologic therapy, with the most common being cabergoline and octreotide (used by 12.4% and 12.2% of patients, respectively). Overall, 18.8% of patients incurred an acromegaly-related inpatient stay; 97.0% used outpatient services other than emergency room (ER) or physician visits; 74.8% had a physician office visit; and 1.8% visited the ER for acromegaly-related reasons. In the 12-month post-index period, 37.0% of patients filed claims for acromegaly-related prescription drugs, and patients with greater than 1 claim had an average of 7.6 prescriptions. The most expensive acromegaly-related costs in this study population were inpatient hospitalizations ($6,754) and prescription drugs ($6,147). Consistent with previous studies, this study confirms that acromegaly is a rare condition associated with multiple comorbidities. Notably, 18.8% of this study population required an inpatient hospital admission during the 12-month post-index period, possibly because of severe comorbidities. Because acromegaly-related costs were driven by hospitalizations and pharmacotherapy, improved management of the disease may reduce the clinical and economic burden experienced by patients with acromegaly.

Applications of ENF criterion in forensic audio, video, computer and telecommunication analysis.
Grigoras, Catalin
2007-04-11
This article reports on the electric network frequency criterion as a means of assessing the integrity of digital audio/video evidence and forensic IT and telecommunication analysis. A brief description is given to different ENF types and phenomena that determine ENF variations. In most situations, to reach a non-authenticity opinion, the visual inspection of spectrograms and comparison with an ENF database are enough. A more detailed investigation, in the time domain, requires short time windows measurements and analyses. The stability of the ENF over geographical distances has been established by comparison of synchronized recordings made at different locations on the same network. Real cases are presented, in which the ENF criterion was used to investigate audio and video files created with secret surveillance systems, a digitized audio/video recording and a TV broadcasted reportage. By applying the ENF Criterion in forensic audio/video analysis, one can determine whether and where a digital recording has been edited, establish whether it was made at the time claimed, and identify the time and date of the registering operation.

Health administrative data can be a valuable tool for disease surveillance and research. Few studies have rigorously evaluated the accuracy of administrative databases for identifying rheumatoid arthritis (RA) patients. Our aim was to validate administrative data algorithms to identify RA patients in Ontario, Canada. We performed a retrospective review of a random sample of 450 patients from 18 rheumatology clinics. Using rheumatologist-reported diagnosis as the reference standard, we tested and validated different combinations of physician billing, hospitalization, and pharmacy data. One hundred forty-nine rheumatology patients were classified as having RA and 301 were classified as not having RA based on our reference standard definition (study RA prevalence 33%). Overall, algorithms that included physician billings had excellent sensitivity (range 94-100%). Specificity and positive predictive value (PPV) were modest to excellent and increased when algorithms included multiple physician claims or specialist claims. The addition of RA medications did not significantly improve algorithm performance. The algorithm of "(1 hospitalization RA code ever) OR (3 physician RA diagnosis codes [claims] with ≥1 by a specialist in a 2-year period)" had a sensitivity of 97%, specificity of 85%, PPV of 76%, and negative predictive value of 98%. Most RA patients (84%) had an RA diagnosis code present in the administrative data within ±1 year of a rheumatologist's documented diagnosis date. We demonstrated that administrative data can be used to identify RA patients with a high degree of accuracy. RA diagnosis date and disease duration are fairly well estimated from administrative data in jurisdictions of universal health care insurance.

Diagnostic errors are an underrecognized source of patient harm, and cardiovascular disease can be challenging to diagnose in the ambulatory setting. Although malpractice data can inform diagnostic error reduction efforts, no studies have examined outpatient cardiovascular malpractice cases in depth. A study was conducted to examine the characteristics of outpatient cardiovascular malpractice cases brought against general medicine practitioners. Some 3,407 closed malpractice claims were analyzed in outpatient general medicine from CRICO Strategies' Comparative Benchmarking System database-the largest detailed database of paid and unpaid malpractice in the world-and multivariate models were created to determine the factors that predicted case outcomes. Among the 153 patients in cardiovascular malpractice cases for whom patient comorbidities were coded, the majority (63%) had at least one traditional cardiac risk factor, such as diabetes, tobacco use, or previous cardiovascular disease. Cardiovascular malpractice cases were more likely to involve an allegation of error in diagnosis (75% vs. 47%, p <0.0001), have high clinical severity (86% vs. 49%, p <0.0001) and result in death (75% vs. 27%, p <0.0001), as compared to noncardiovascular cases. Initial diagnoses of nonspecific chest pain and mimics of cardiovascular pain (for example, esophageal disease) were common and independently increased the likelihood of a claim resulting in a payment (p <0.01). Cardiovascular malpractice cases against outpatient general medicine physicians mostly occur in patients with conventional risk factors for coronary artery disease and are often diagnosed with common mimics of cardiovascular pain. These findings suggest that these patients may be high-yield targets for preventing diagnostic errors in the ambulatory setting. Copyright © 2017 The Authors. Published by Elsevier Inc.

To develop a software solution that supports management and clinical review of patient data from electronic medical records databases or claims databases for pharmacoepidemiological drug safety studies. We used open source software to build a data management system and an internet application with a Flex client on a Java application server with a MySQL database backend. The application is hosted on Amazon Elastic Compute Cloud. This solution named Phynx supports data management, Web-based display of electronic patient information, and interactive review of patient-level information in the individual clinical context. This system was applied to a dataset from the UK General Practice Research Database (GPRD). Our solution can be setup and customized with limited programming resources, and there is almost no extra cost for software. Access times are short, the displayed information is structured in chronological order and visually attractive, and selected information such as drug exposure can be blinded. External experts can review patient profiles and save evaluations and comments via a common Web browser. Phynx provides a flexible and economical solution for patient-level review of electronic medical information from databases considering the individual clinical context. It can therefore make an important contribution to an efficient validation of outcome assessment in drug safety database studies.

Pharmacoeconomic models of Helicobacter (H) pylori eradication have been frequently cited but never validated. Examine retrospectively whether H pylori pharmacoeconomic models direct decision makers to cost-effective therapeutic choices. We first replicated and then validated 2 models, replacing model assumptions with empirical data from a multipayer claims database. Database subjects were 435 commercially insured U.S. patients treated with bismuthmetronidazole- tetracycline (BMT), proton pump inhibitor (PPI)-clarithromycin, or PPI-amoxicillin. Patients met >1 clinical requirement (ulcer disease, gastritis/duodenitis, stomach function disorder, abdominal pain, H pylori infection, endoscopy, or H pylori assay). Sensitivity analyses included only patients with ulcer diagnosis or gastrointestinal specialist care. Outcome measures were: (1) rates of eradication retreatment; (2) use of office visits, hospitalizations, endoscopies, and antisecretory medication; and (3) cost per effectively treated (nonretreated) patient. Model results overstated the cost-effectiveness of PPI-clarithromycin and underestimated the cost-effectiveness of BMT. Prior to empirical adjustment, costs per effectively treated patient were 1,001 US dollars, 980 US dollars, and 1,730 US dollars for BMT, PPIclarithromycin, and PPI-amoxicillin, respectively. Estimates after adjustment were US dollars for BMT, 1,118 US dollars for PPI-clarithromycin, and 1,131 US dollars for PPI-amoxicillin. Key model assumptions that proved retrospectively incorrect were largely unsupported by either empirical evidence or systematic assessment of expert opinion. Organizations with access to medical and pharmacy claims databases should test key assumptions of influential models to determine their validity. Journal peer-review processes should pay particular attention to the basis of model assumptions.
The benefits of data linkage for firefighter injury surveillance

Background While survey data are available for national estimates of fire events and firefighter fatalities, data on firefighter injury at the national and local levels remain incomplete and unreliable. Data linkage provides a vehicle to maximise case detection and deepen injury description for the US fire service. Methods By linking departmental Human Resources records, despatch data, workers' compensation and first reports of injury, researchers were able to describe reported non-fatal injuries to 3063 uniformed members of the Philadelphia Fire Department (PFD), for the period of 2005 through 2013. Results Among all four databases, the overall linkage rate was 56%. Among three of the four databases, the linkage rate was 88%. Because there was duplication of some variables among the datasets, we were able to deeply describe all the linked injuries in the master database. 45.5% of uniformed PFD members reported at least one injury during the study period. Strains, falls, burns and struck-by injuries were the most common causes. Burns resulted in the highest lost time claim payout, and strains accounted for the highest medical claim cost. More than 70% of injuries occurred in the first 15 years of experience. Discussion Data linkage provided three new benefits: (1) creation of a new variable—years of experience, (2) reduction of misclassification bias when determining cause of injury, leading to more accurate estimates of cost and (3) visualisation of injury rates when controlling for the number of fire department responses, allowing for the generation of hypotheses to investigate injury hot spots.

To review the evidence on the provision of psychotherapy for claimants who are suffering from depression and receiving wage replacement benefits. A literature review was performed using PubMed and EMBASE. Results from three studies are discussed. The first is a systematic review and individual patient data meta-analysis of randomized controlled trials to assess the relative effectiveness of cognitive behavioral therapy (CBT) for depression in patients receiving disability benefits. A non-significant trend showed that the effect of CBT was greater in patients receiving benefits (34 patients) than those not receiving disability benefits (193 patients) on the Beck Depression Inventory; mean difference (95% confidence interval [CI]) = -4.46 (-12.21 to 3.30). The second study is an analysis of a large insurance administrative database consisting of 10,338 long-term disability claims for depression. Receipt of psychotherapy was associated with faster claim closure (hazard ratio = 1.42; 95% CI = 1.33 to 1.52). The third study evaluated the effectiveness of standard CBT vs work-focused CBT in 168 employees with common mental health problems (depression, anxiety and adjustment disorders). Employees receiving work-focused CBT returned to work 65 days earlier on average than those receiving standard CBT. Limited evidence shows that psychotherapy is effective in claimants suffering from depression who are in receipt of wage replacement benefits. At this time, clinicians and insurers should continue to recommend psychotherapy as a treatment management strategy for claimants with depression. Larger comparative trials, conducted in collaboration with disability insurers, will lead to increased confidence in estimates.

Given the availability of extensive digitized healthcare data from medical records, claims and prescription information, it is now possible to use hypothesis-free, data-driven approaches to mine medical databases for novel insight. The goal of this analysis was to demonstrate the use of artificial intelligence based methods such as Bayesian networks to open up opportunities for creation of new knowledge in management of chronic conditions. Hospital level Medicare claims data containing discharge numbers for most common diagnoses were analyzed in a hypothesis-free manner using Bayesian networks learning methodology. While many interactions identified between discharge rates of diagnoses using this data set are supported by current medical knowledge, a novel interaction linking asthma and renal failure was discovered. This interaction is non-obvious and had not been looked at by the research and clinical communities in epidemiological or clinical data. A plausible pharmacological explanation of this link is proposed together with a verification of the risk significance by conventional statistical analysis. Potential clinical and molecular pathways defining the relationship between commonly used asthma medications and renal disease are discussed. The study underscores the need for further epidemiological research to validate this novel hypothesis. Validation will lead to advancement in clinical treatment of asthma & bronchitis, thereby, improving patient outcomes and leading to long term cost savings. In summary, this study demonstrates that application of advanced artificial intelligence methods in healthcare has the potential to enhance the quality of care by discovering non-obvious, clinically relevant relationships and enabling timely care intervention.

Predictive factors associated with increased risk of medical malpractice litigation have been identified, including severity of injury, physician sex, and error in diagnosis. However, there is a paucity of literature investigating informed consent in spinal surgery malpractice. To investigate the failure to obtain informed consent as an allegation in medical malpractice claims for patients undergoing a spinal procedure. In this retrospective cohort study, a national medicolegal database was searched for malpractice claim cases related to spinal surgery for all years available (ie, January 1, 1980, through December 31, 2015). Failure to obtain informed consent and associated medical malpractice case verdict. A total of 233 patients (117 [50.4%] male and 116 [49.8%] female; 80 with no informed consent allegation and 153 who cited lack of informed consent) who underwent spinal surgery and filed a malpractice claim were studied (mean [SD] age, 47.1 [13.1] years in the total group, 45.8 [12.9] years in the control group, and 47.9 [13.3] years in the informed consent group). Median interval between year of surgery and year of verdict was 5.4 years (interquartile range, 4-7 years). The most common informed consent allegations were failure to explain risks and adverse effects of surgery (52 [30.4%]) and failure to explain alternative treatment options (17 [9.9%]). In bivariate analysis, patients in the control group were more likely to require additional surgery (45 [56.3%] vs 53 [34.6%], P = .002) and have more permanent injuries compared with the informed consent group (46 [57.5%] vs 63 [42.0%], P = .03). On multivariable regression analysis, permanent injuries were more often associated with indemnity payment after a plaintiff verdict (odds ratio [OR], 3.12; 95% CI, 1.46-6.65; P = .003) or a settlement (OR, 6.26; 95% CI, 1.06-36.70; P = .04). Informed consent allegations were significantly associated with less severe (temporary or emotional) injury (OR, 0.52; 95% CI, 0.28-0.97; P = .04). In addition, allegations of informed consent were found to be predictive of a defense verdict vs a plaintiff ruling (OR, 0.41; 95% CI, 0.17-0.98; P = .046) or settlement (OR, 0.01; 95% CI, 0.001-0.15; P < .001). Lack of informed consent is an important cause of medical malpractice litigation. Although associated with a lower rate of indemnity payments, malpractice lawsuits, including informed consent allegations, still present a time, money, and reputation toll for physicians. The findings of this study can therefore help to improve preoperative discussions to protect spinal surgeons from malpractice claims and ensure that patients are better informed.

In this paper we aim to discuss how Portuguese prisoners know and what they feel about surveillance mechanisms related to the inclusion and deletion of the DNA profiles of convicted criminals in the national forensic database. Through a set of interviews with individuals currently imprisoned we focus on the ways this group perceives forensic DNA technologies. While the institutional and political discourses maintain that the restricted use and application of DNA profiles within the national forensic database protects individuals' rights, the prisoners claim that police misuse of such technologies potentially makes it difficult to escape from surveillance and acts as a mean of reinforcing the stigma of delinquency. The prisoners also argue that additional intensive and extensive use of surveillance devices might be more protective of their own individual rights and might possibly increase potential for exoneration.

Massive parallelization of serial inference algorithms for a complex generalized linear model
Suchard, Marc A.; Simpson, Shawn E.; Zorych, Ivan; Ryan, Patrick; Madigan, David
2014-01-01
Following a series of high-profile drug safety disasters in recent years, many countries are redoubling their efforts to ensure the safety of licensed medical products. Large-scale observational databases such as claims databases or electronic health record systems are attracting particular attention in this regard, but present significant methodological and computational concerns. In this paper we show how high-performance statistical computation, including graphics processing units, relatively inexpensive highly parallel computing devices, can enable complex methods in large databases. We focus on optimization and massive parallelization of cyclic coordinate descent approaches to fit a conditioned generalized linear model involving tens of millions of observations and thousands of predictors in a Bayesian context. We find orders-of-magnitude improvement in overall run-time. Coordinate descent approaches are ubiquitous in high-dimensional statistics and the algorithms we propose open up exciting new methodological possibilities with the potential to significantly improve drug safety.

Patients with coronary artery disease with diabetes, a history of acute coronary syndromes, cerebrovascular atherosclerotic disease, or peripheral arterial disease are at particularly high risk for a cardiovascular (CV) event and can be defined as having high-risk atherosclerotic cardiovascular disease (ASCVD). The objective of this study is to examine healthcare resource utilization (HRU) and total healthcare costs (THC) for patients with ASCVD in a commercially insured population. A retrospective cohort study was conducted using a large, US employer-based, claims database. Patients with an ASCVD diagnosis between October 1, 2008 to September 30, 2009 who met eligibility requirements were included. All-cause and ASCVD-related HRU and THC for the first and second year of follow-up were examined for all patients and by the number of arterial beds affected. Adjusted THC were compared across groups with and without polyvascular disease. The analysis included 152,290 patients with ASCVD. Use of CV-related medications, hospitalizations, and office visits were highest among patients with three arterial beds affected. Mean all-cause THC for patients with ASCVD were ∼$19,000 per patient in Year 1 or Year 2, with medical costs as the main driver. ASCVD-related THC were also similar for Year 1 ($8699) and Year 2 ($7925) across all patients. Adjusted all-cause and ASCVD-related THC for both years were greatest for patients with three affected arterial beds compared with one or two affected beds (p < 0.001 for each comparison). This is the first study in a managed care setting to systematically estimate all-cause and ASCVD-related THC for an aggregated population of ASCVD patients at high risk for a CV event. The economic burden of ASCVD in working-age patients in the US is substantial. Significantly higher HRU and costs were found in patients with polyvascular disease compared with those with only one affected bed.

Conflicting evidence exists regarding predictors of and antithrombotic benefit on mortality in hospitalised acutely-ill medical patients. We compared mortality risk within 90 days post-discharge among medically ill patients who did and did not receive antithrombotics. This retrospective claims analysis included patients ≥ 40 years with nonsurgical hospitalisation ≥ 2 days between 2005 and 2009 using the HealthCore Integrated Research Database. Antithrombotic use (i.e. anticoagulants and antiplatelets) post-discharge was captured from pharmacy claims. All-cause mortality was determined from Social Security Death Index; cause of death was identified from National Death Index database. Kaplan-Meier survival curves were generated and hazard ratios (HR) for mortality risk were estimated using Cox proportional hazards models. Patients prescribed anticoagulants or antiplatelets post-discharge had lower risk of short-term mortality. For the anticoagulant model, the most significant predictors of mortality were malignant/benign neoplasms (hazard ratio [HR] 1.6, 95% confidence interval [CI] 1.5-1.7), liver disease (HR 1.6, 95% CI 1.5-1.7), anticoagulant omission (HR 1.6, 95% CI 1.4-1.8), gastrointestinal or respiratory tract intubations (HR 1.5, 95% CI 1.3-1.7), and blood dyscrasias (HR 1.4, 95% CI 1.4-1.5). For the antiplatelet model, the most significant predictors of mortality were antiplatelet omission (HR 3.7, 95% CI 3.3-4.1), liver disease (HR 1.6, 95% CI 1.4-1.7), malignant/benign neoplasms (HR 1.6, 95% CI 1.5-1.6), gastrointestinal or respiratory tract intubations (HR 1.5, 95% CI 1.3-1.7), and blood dyscrasias (HR 1.4, 95% CI 1.4-1.5). These mortality risk factors may guide future studies assessing potential benefits of antithrombotics in specific subsets of patients.

For many years, the standard of care for patients diagnosed with deep vein thrombosis (DVT) has been low-molecular-weight heparin (LMWH) bridging to an oral Vitamin-K antagonist (VKA). The availability of new non-VKA oral anticoagulants (NOAC) agents as monotherapy may reduce the likelihood of hospitalization for DVT patients. To compare hospital visit costs of DVT patients treated with rivaroxaban and LMWH/warfarin. A retrospective claim analysis was conducted using the MarketScan Hospital Drug Database for care provided between January 2011 and December 2013. Adult patients using rivaroxaban or LMWH/warfarin with a primary diagnosis of DVT during the first day of a hospital visit were identified (i.e., index hospital visit). Based on propensity-score methods, historical LMWH/warfarin patients (i.e., patients who received LMWH/warfarin before the approval of rivaroxaban) were matched 4:1 to rivaroxaban patients. The hospital-visit cost difference between these groups was evaluated for the index hospital visit, as well as for total hospital-visit costs (i.e., including index and subsequent hospital visit costs). All rivaroxaban users (n = 134) in the database were well-matched with four LMWH/warfarin users (n = 536). The mean hospital-visit costs were $5257 for the rivaroxaban cohort and $6764 in the matched-cohort of patients using LMWH/warfarin. The $1508 cost difference was statistically significant between cohorts (95% CI = [-$2296; -$580]; p-value = 0.002). Total hospital-visit costs were lower for rivaroxaban compared to LMWH/warfarin users within 1, 2, 3, and 6 months after index visit (significantly lower within 1 and 3 months, p-values <0.05) LIMITATIONS: Limitations were inherent to administrative-claims data, completeness of baseline characteristics, adjustments restricted to observational factors, and lastly the sample size of the rivaroxaban cohort. The availability of rivaroxaban significantly reduced the costs of hospital visits in patients with DVT treated with rivaroxaban compared to LMWH/warfarin.

After the successful launch in May 2003, the Hayabusa (MUSES-C) mission of JAXA/ISAS will collect surface materials (e.g., regolith) of several hundred mg to several g in total from the S-type near Earth asteroid (25143) Itokawa in late 2005 and bring them back to ground laboratories in the summer of 2007. The retrieved samples will be given initial analysis at the JAXA/ISAS astromaterial curation facility, which is currently in the preparation for its construction, by the Hayabusa Asteroidal Sample Preliminary Examination Team (HASPET). HASPET is consisted of the ISAS Hayabusa team, the international partners from NASA and Australia and all-Japan meteoritic scientists to be selected as outsourcing parts of the initial analyses. The initial analysis to characterize general aspects of returned samples can consume only 15 % of its total mass and must complete the whole analyses including the database building before international AO for detailed analyses within the maximum of 1 year. Confident exercise of non-destructive, micro-analyses whenever possible are thus vital for the HASPET analysis. In the purpose to survey what kinds and levels of micro-analysis techniques in respective fields, from major elements and mineralogy to trace and isotopic elements and organics, are available in Japan at present, ISAS has conducted the HASPET open competitions in 2000-01 and 2004. The initial evaluation was made by multiple domestic peer reviews. Applicants were then provided two kinds of unknown asteroid sample analogs in order to conduct proposed analysis with self-claimed amount of samples in self-claimed duration. After the completion of multiple, international peer reviews, the Selection Committee compiled evaluations and recommended the finalists of each round. The final members of the HASPET will be appointed about 2 years prior to the Earth return. Then they will conduct a test-run of the whole initial analysis procedures at the ISAS astromaterial curation facility and their respective analysis facilities. This talk also summarizes the curation facility design and plans of initial analysis procedure flow.
Representing inequities in the distribution of socio-economic benefits and environmental risk.
Louis, Garric E; Magpili, Luna M
2002-10-01
There is currently no standard method for analyzing claims of environmental inequity. Neither is there a database of statistics on the extent of relationship between regional indicators of environmental quality, likely sources of pollution, and the demographic characteristics of affected populations. The resolution of environmental disputes is often hampered by inadequate communication between stakeholder groups about their perceptions and prioritization of the issues in dispute and by differential access to information about the issues by each stakeholder group. This paper describes a web-based tool, ICEP, that uses multi-layered GIS maps to establish a standard method for analyzing claims of environmental inequity and establish a database of correlation coefficients between environmental indicators, industry type by SIC code, and demographic characteristics of the population in proximity to noxious facilities. The maps are generated from stakeholder reports of environmental quality and are designed to be accessible via the Internet. This provides stakeholders with direct access to graphical displays of the perceptions of their co-stakeholders and provides all groups with links to relevant information sources about the issues in dispute. ICEP enhances existing community environmental websites like Scorecard and Envirofacts by providing displays of median household income as a measure of the distribution of benefits accrued within an area.

Electronic medical claims (EMCs) can be used to accurately predict the occurrence of a variety of diseases, which can contribute to precise medical interventions. While there is a growing interest in the application of machine learning (ML) techniques to address clinical problems, the use of deep-learning in healthcare have just gained attention recently. Deep learning, such as deep neural network (DNN), has achieved impressive results in the areas of speech recognition, computer vision, and natural language processing in recent years. However, deep learning is often difficult to comprehend due to the complexities in its framework. Furthermore, this method has not yet been demonstrated to achieve a better performance comparing to other conventional ML algorithms in disease prediction tasks using EMCs. In this study, we utilize a large population-based EMC database of around 800,000 patients to compare DNN with three other ML approaches for predicting 5-year stroke occurrence. The result shows that DNN and gradient boosting decision tree (GBDT) can result in similarly high prediction accuracies that are better compared to logistic regression (LR) and support vector machine (SVM) approaches. Meanwhile, DNN achieves optimal results by using lesser amounts of patient data when comparing to GBDT method.

The purpose of this study is to report on the effect of using CHA 2 DS 2 VASc (congestive heart failure, hypertension, age ≥75 years [doubled], type 1 or type 2 diabetes mellitus, stroke or transient ischemic attack or thromboembolism [doubled], vascular disease [prior myocardial infarction, peripheral artery disease, or aortic plaque], age 65-75 years, sex category [female]) rather than CHADS 2 (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, and prior stroke) to determine candidacy for anticoagulant prophylaxis in insured patients with atrial fibrillation (AF). Six administrative claims databases that included medical and pharmacy claims for patients aged ≥18 years with a new or existing diagnosis of AF and patient outcomes assessed for 1 year after diagnosis were analyzed. Retrospective health plan data analyses were performed using a software tool (Anticoagulant Quality Improvement Analyzer). Study measures included stroke risk (identified by CHADS 2 and CHA 2 DS 2 VASc scores), bleeding risk (identified by the Anticoagulation and Risk Factors in Atrial Fibrillation score), and anticoagulant use. A total of 115,906 patients with AF (range of mean ages among the 6 databases, 56-79 years) met the inclusion criteria. All ranges reported represent the minimum and maximum values among the 6 databases. Using the CHA 2 DS 2 VASc compared with the CHADS 2 index to assess stroke risk resulted in a 23% to 32% increase in patients considered potential candidates for anticoagulant prophylaxis. This translated to a 38% to 114% increase in the number of ostensibly undertreated patients. Among patients with high stroke and low bleeding risk, 18% to 28% more patients were considered potential candidates for anticoagulation treatment using CHA 2 DS 2 VASc compared with CHADS 2 , or a 57% to 151% increase in the number of undertreated patients. Use of the CHA 2 DS 2 VASc score to determine the risk of stroke increased the number of AF patients for whom oral anticoagulation would be recommended. Additional research is needed to determine whether this paradigm shift to greater use of oral anticoagulants improves patient outcomes. Copyright © 2016 Elsevier HS Journals, Inc.

Précis The rapid implementation and continuing expansion of forensic DNA databases around the world has been supported by claims about their effectiveness in criminal investigations and challenged by assertions of the resulting intrusiveness into individual privacy. These two competing perspectives provide the basis for ongoing considerations about the categories of persons who should be subject to nonconsensual DNA sampling and profile retention as well as the uses to which such profiles should be put. This paper uses the example of the current arrangements for forensic DNA databasing in England & Wales to discuss the ways in which the legislative and operational basis for police DNA databasing is reliant upon continuous deliberations over these and other matters by a range of key stakeholders. We also assess the effects of the recent innovative use of DNA databasing for ‘familial searching’ in this jurisdiction in order to show how agreed understandings about the appropriate uses of DNA can become unsettled and reformulated even where their investigative effectiveness is uncontested. We conclude by making some observations about the future of what is recognised to be the largest forensic DNA database in the world. PMID:16240734
Use of large healthcare databases for rheumatology clinical research.
Desai, Rishi J; Solomon, Daniel H
2017-03-01
Large healthcare databases, which contain data collected during routinely delivered healthcare to patients, can serve as a valuable resource for generating actionable evidence to assist medical and healthcare policy decision-making. In this review, we summarize use of large healthcare databases in rheumatology clinical research. Large healthcare data are critical to evaluate medication safety and effectiveness in patients with rheumatologic conditions. Three major sources of large healthcare data are: first, electronic medical records, second, health insurance claims, and third, patient registries. Each of these sources offers unique advantages, but also has some inherent limitations. To address some of these limitations and maximize the utility of these data sources for evidence generation, recent efforts have focused on linking different data sources. Innovations such as randomized registry trials, which aim to facilitate design of low-cost randomized controlled trials built on existing infrastructure provided by large healthcare databases, are likely to make clinical research more efficient in coming years. Harnessing the power of information contained in large healthcare databases, while paying close attention to their inherent limitations, is critical to generate a rigorous evidence-base for medical decision-making and ultimately enhancing patient care.

Claims that savings realization is greater in energy savings performance contracts (ESPCs) are rampant at least among energy service company representatives and other ESPC cheerleaders. But hard supporting evidence for these claims has been virtually non-existent. The Department of Energy's Federal Energy Management Program uses its Compliance Tracking System (CTS) database to document the performance of federal buildings and projects towards meeting various federal energy-saving goals. This paper focuses on preliminary analysis from CTS to understand and compare the performance of federal ESPCs with projects that have been implemented with more conventional government appropriations funding. The authors have found preliminarymore » evidence using CTS that shows markedly higher savings realization rates among ESPC projects than appropriations-funded ones. There are numerous caveats to the data comparison that clamor for further study, but the difference is still intriguing. If borne out, this finding will provide concrete support to the idea that ESPCs guarantees and measurement and verification, long touted by energy service companies (ESCOs) as offering savings assurance, may truly yield substantial benefits. If ESPCs actually do perform better (i.e., have higher realization rates and savings persistence) than conventional bid-to-spec projects, the perceived premium for conducting them may look like a very good deal after all.« less

Objective To assess costs, effectiveness, and cost-effectiveness of inhaled corticosteroids (ICS) augmenting bronchodilator treatment for chronic obstructive pulmonary disease (COPD). Data Sources Claims between 1997 and 2005 from a large managed care database. Study Design Individual-level, fixed-effects regression models estimated the effects of initiating ICS on medical expenses and likelihood of severe exacerbation. Bootstrapping provided estimates of the incremental cost per severe exacerbation avoided. Data Extraction Methods COPD patients aged 40 or older with ≥15 months of continuous eligibility were identified. Monthly observations for 1 year before and up to 2 years following initiation of bronchodilators were constructed. Principal Findings ICS treatment reduced monthly risk of severe exacerbation by 25 percent. Total costs with ICS increased for 16 months, but declined thereafter. ICS use was cost saving 46 percent of the time, with an incremental cost-effectiveness ratio of $2,973 per exacerbation avoided; for patients ≥50 years old, ICS was cost saving 57 percent of time. Conclusions ICS treatment reduces exacerbations, with an increase in total costs initially for the full sample. Compared with younger patients with COPD, patients aged 50 or older have reduced costs and improved outcomes. The estimated cost per severe exacerbation avoided, however, may be high for either group because of uncertainty as reflected by the large standard errors of the parameter estimates. PMID:18671750
The effect of access restrictions on the vintage of drugs used by Medicaid enrollees.
Lichtenberg, Frank R
2005-01-01
To examine the extent to which recent Medicaid drug access restrictions, such as preferred drug lists (PDLs), may affect the vintage (or time since Food and Drug Administration approval) of 6 types of drugs used by Medicaid beneficiaries. Retrospective claims database analysis using National Drug Code pharmacy claims data. A regression model was developed to analyze the effect that Medicaid access restrictions had on the vintage of medications prescribed in 6 different therapeutic categories. A "difference in differences" approach was used to compare the change in vintage of medications prescribed in Medicaid versus non-Medicaid patients between the January-June 2001 and July-December 2003 study periods. The results of the regression model showed that PDLs increased the age of Medicaid prescriptions by less than 1 year for drugs in 5 of the 6 therapeutic classes analyzed. In the case of pain management medications, the increase was more than 1.2 years. The results of the regression model suggest that Medicaid drug access restriction programs (e.g., PDLs) have resulted in an increase in the age of drugs prescribed for Medicaid beneficiaries versus non-Medicaid patients. Since previous research has suggested a clinical and economic advantage to utilizing newer versus older drugs, further research should be conducted to explore how these medication restriction policies may unduly affect Medicaid beneficiaries compared with privately insured patients.
Understanding the relationship between environmental quality ...
In 2014, approximately 17.7 million (7.4%) of United States (U.S.) adults had asthma. In 2009 alone, asthma caused 479,300 hospitalizations and 1.9 million emergency room visits. Asthma has been associated with exposure to air pollution and socioeconomic status, and reductions in atopic sensitization, an asthma precursor, have been associated with green space exposure, suggesting a role of environmental quality. We linked the Environmental Quality Index (EQI), representing 5 environmental domains (air, water, land, built, and sociodemographic) for all US counties (N=3,141) from 2000—2005 to Truven Health’s MarketScan individual claims database to examine associations between county-level EQI and asthma among U.S. adults ages 18-65 from 2003-2010. We defined asthma as having at least 1 claim (International Classification of Disease 9th edition, code 493) during the study period. We used random intercept multi-level Poisson regression clustered by county, adjusted for 10-year age category and sex, to estimate fixed effects of quintiles of the EQI on asthma prevalence. We examined modification by urbanicity through stratification by 4 rural-urban continuum codes (RUCC) ranging from most urban (RUCC1) to rural (RUCC4). Approximately 3% of adults in MarketScan have asthma claims. Comparing the highest EQI quintile (worst quality) to lowest EQI quintile (best quality), we observed increased asthma claims associated with worse environmental quality (prevalence rat

The Food and Drug Administration's Mini-Sentinel pilot program initially aims to conduct active surveillance to refine safety signals that emerge for marketed medical products. A key facet of this surveillance is to develop and understand the validity of algorithms for identifying health outcomes of interest from administrative and claims data. This article summarizes the process and findings of the algorithm review of anaphylaxis. PubMed and Iowa Drug Information Service searches were conducted to identify citations applicable to the anaphylaxis health outcome of interest. Level 1 abstract reviews and Level 2 full-text reviews were conducted to find articles using administrative and claims data to identify anaphylaxis and including validation estimates of the coding algorithms. Our search revealed limited literature focusing on anaphylaxis that provided administrative and claims data-based algorithms and validation estimates. Only four studies identified via literature searches provided validated algorithms; however, two additional studies were identified by Mini-Sentinel collaborators and were incorporated. The International Classification of Diseases, Ninth Revision, codes varied, as did the positive predictive value, depending on the cohort characteristics and the specific codes used to identify anaphylaxis. Research needs to be conducted on designing validation studies to test anaphylaxis algorithms and estimating their predictive power, sensitivity, and specificity.

False and misleading advertising for drugs can harm consumers and the healthcare system, and previous research has demonstrated that physician-targeted drug advertisements may be misleading. However, there is a dearth of research comparing consumer-targeted drug advertising to evidence to evaluate whether misleading or false information is being presented in these ads. To compare claims in consumer-targeted television drug advertising to evidence, in order to evaluate the frequency of false or misleading television drug advertising targeted to consumers. A content analysis of a cross-section of television advertisements for prescription and nonprescription drugs aired from 2008 through 2010. We analyzed commercial segments containing prescription and nonprescription drug advertisements randomly selected from the Vanderbilt Television News Archive, a census of national news broadcasts. For each advertisement, the most-emphasized claim in each ad was identified based on claim iteration, mode of communication, duration and placement. This claim was then compared to evidence by trained coders, and categorized as being objectively true, potentially misleading, or false. Potentially misleading claims omitted important information, exaggerated information, made lifestyle associations, or expressed opinions. False claims were factually false or unsubstantiated. Of the most emphasized claims in prescription (n = 84) and nonprescription (n = 84) drug advertisements, 33 % were objectively true, 57 % were potentially misleading and 10 % were false. In prescription drug ads, there were more objectively true claims (43 %) and fewer false claims (2 %) than in nonprescription drug ads (23 % objectively true, 7 % false). There were similar numbers of potentially misleading claims in prescription (55 %) and nonprescription (61 %) drug ads. Potentially misleading claims are prevalent throughout consumer-targeted prescription and nonprescription drug advertising on television. These results are in conflict with proponents who argue the social value of drug advertising is found in informing consumers about drugs.

Accurate identification of underlying health conditions is important to fully adjust for confounders in studies using insurer claims data. Our objective was to evaluate the ability of four modifications to a standard claims-based measure to estimate the prevalence of select comorbid conditions compared with national prevalence estimates. In a cohort of 11,973 privately insured women aged 18-64 years with mastectomy from 1/04-12/11 in the HealthCore Integrated Research Database, we identified diabetes, hypertension, deficiency anemia, smoking, and obesity from inpatient and outpatient claims for the year prior to surgery using four different algorithms. The standard comorbidity measure was compared to revised algorithms which included outpatient medications for diabetes, hypertension and smoking; an expanded timeframe encompassing the mastectomy admission; and an adjusted time interval and number of required outpatient claims. A χ2 test of proportions was used to compare prevalence estimates for 5 conditions in the mastectomy population to national health survey datasets (Behavioral Risk Factor Surveillance System and the National Health and Nutrition Examination Survey). Medical record review was conducted for a sample of women to validate the identification of smoking and obesity. Compared to the standard claims algorithm, use of the modified algorithms increased prevalence from 4.79 to 6.79 % for diabetes, 14.75 to 24.87 % for hypertension, 4.23 to 6.65 % for deficiency anemia, 1.78 to 12.87 % for smoking, and 1.14 to 6.31 % for obesity. The revised estimates were more similar, but not statistically equivalent, to nationally reported prevalence estimates. Medical record review revealed low sensitivity (17.86 %) to capture obesity in the claims, moderate negative predictive value (NPV, 71.78 %) and high specificity (99.15 %) and positive predictive value (PPV, 90.91 %); the claims algorithm for current smoking had relatively low sensitivity (62.50 %) and PPV (50.00 %), but high specificity (92.19 %) and NPV (95.16 %). Modifications to a standard comorbidity measure resulted in prevalence estimates that were closer to expected estimates for non-elderly women than the standard measure. Adjustment of the standard claims algorithm to identify underlying comorbid conditions should be considered depending on the specific conditions and the patient population studied.

To categorize and understand the reasons behind ophthalmic clinical negligence claims in the National Health Service and how such claims can be avoided. Retrospective analyses of all ophthalmic clinical negligence claims between 1995 and 2009 were carried out. Data were obtained from the National Health Service Litigation Authority through the Freedom of Information Act. Claims were classified according to ophthalmic subspecialty, mean payment per subspecialty, severity, paid-to-closed ratio, and cost. One thousand two hundred fifty-three ophthalmology-related claims occurring from 1995 through 2009. Of these, 963 claims were closed over the 15-year period. Eighty-four were excluded because of insufficient case data. Retrospective analysis of all public sector ophthalmology litigation claims over a 15-year period in England. Subspecialty pertaining to claim, mean payment per claim, and severity of outcome of clinical incident. Nine hundred sixty-three claims were closed over a 15-year period, of which 67% resulted in payment. The total cost of claims was £32.1 million ($50.3 million), with a mean payment per claim of £33 300 ($52 300). The specialties with the highest mean payment per claim were neuro-ophthalmology and pediatric ophthalmology. Cataract subspecialty had the highest number of claims, accounting for 34% of all claims. Overall, the number of litigation claims in ophthalmology is low, relative to the high volume of outpatient and surgical workload. Copyright © 2013 American Academy of Ophthalmology.

[Privacy and public benefit in using large scale health databases].
Yamamoto, Ryuichi
2014-01-01
In Japan, large scale heath databases were constructed in a few years, such as National Claim insurance and health checkup database (NDB) and Japanese Sentinel project. But there are some legal issues for making adequate balance between privacy and public benefit by using such databases. NDB is carried based on the act for elderly person's health care but in this act, nothing is mentioned for using this database for general public benefit. Therefore researchers who use this database are forced to pay much concern about anonymization and information security that may disturb the research work itself. Japanese Sentinel project is a national project to detecting drug adverse reaction using large scale distributed clinical databases of large hospitals. Although patients give the future consent for general such purpose for public good, it is still under discussion using insufficiently anonymized data. Generally speaking, researchers of study for public benefit will not infringe patient's privacy, but vague and complex requirements of legislation about personal data protection may disturb the researches. Medical science does not progress without using clinical information, therefore the adequate legislation that is simple and clear for both researchers and patients is strongly required. In Japan, the specific act for balancing privacy and public benefit is now under discussion. The author recommended the researchers including the field of pharmacology should pay attention to, participate in the discussion of, and make suggestion to such act or regulations.

To describe characteristics of closed medical professional liability (MPL) claims against ophthalmologists in the United States. Retrospective analysis of MPL claims from 2006-2015. Data were obtained from the Physician Insurers Association of America (PIAA) Data Sharing Project (DSP). Comparison was made between ophthalmology and all healthcare specialties for physician demographics, prevalence and costs associated with closed claims, and resolution of claims. The most prevalent chief medical factor, presenting medical condition, operative procedure, outcomes, and resolution of ophthalmology claims were compared between the 2006-2010 and 2011-2015 periods. From 2006-2015, 90 743 MPL claims were closed: 2.6% (2325/90 743) of closed claims and 2.2% (564/24 670) of all paid claims were against ophthalmologists. Retrospective analysis of MPL claims captured by the PIAA DSP over a 10-year period. Subspecialty pertaining to the claim, number of claims closed and paid, indemnity paid, allocated loss adjustment expenses, chief medical factor, presenting medical condition, operative procedure, outcome, and resolution. Only 24% of closed claims against ophthalmologists resulted in payment. Two-thirds were dropped, withdrawn, or dismissed. Ninety percent of claims that received a verdict were favorable toward the ophthalmologist. Cataract and cornea surgeries were the most prevalent and most costly operative procedures, accounting for 50% of all claims and $47 641 376 and $32 570 148 in total paid indemnity, respectively. Average indemnity was higher for corneal procedures ($304 476) than vitreoretinal procedures ($270 141) or oculoplastic procedures on the eyelid ($222 471) or orbit and eyeball ($183 467). The prevalence and cost of claims related to endophthalmitis declined from 2006-2010 (n = 38/1160 [3.3%]; average indemnity, $516 875) period to the 2011-2015 (n = 26/1165 [2.2%]; average indemnity, $247 083) period. Average indemnity paid ($280 227 vs. $335 578) and amount spent on legal defense ($41 450 vs. $46 391) was slightly lower among ophthalmologists compared with all healthcare specialties, respectively. Ophthalmology has a relatively low number of malpractice claims reported compared with other healthcare specialties and shows less spending on average indemnity and defense. Further studies are needed to investigate the reasons for the higher prevalence of claims related to cataract and corneal surgeries and the higher average indemnity paid for corneal procedures relative to vitreoretinal or oculoplastic procedures.

Retrieving Tract Variables From Acoustics: A Comparison of Different Machine Learning Strategies.
Mitra, Vikramjit; Nam, Hosung; Espy-Wilson, Carol Y; Saltzman, Elliot; Goldstein, Louis
2010-09-13
Many different studies have claimed that articulatory information can be used to improve the performance of automatic speech recognition systems. Unfortunately, such articulatory information is not readily available in typical speaker-listener situations. Consequently, such information has to be estimated from the acoustic signal in a process which is usually termed "speech-inversion." This study aims to propose and compare various machine learning strategies for speech inversion: Trajectory mixture density networks (TMDNs), feedforward artificial neural networks (FF-ANN), support vector regression (SVR), autoregressive artificial neural network (AR-ANN), and distal supervised learning (DSL). Further, using a database generated by the Haskins Laboratories speech production model, we test the claim that information regarding constrictions produced by the distinct organs of the vocal tract (vocal tract variables) is superior to flesh-point information (articulatory pellet trajectories) for the inversion process.

Adverse drug events (ADEs) may lead to serious injury and may result in malpractice claims. While ADEs resulting in claims are not representative of all ADEs, such data provide a useful resource for studying ADEs. Therefore, we conducted a review of medication-related malpractice claims to study their frequency, nature, and costs and to assess the human factor failures associated with preventable ADEs. We also assessed the potential benefits of proved effective ADE prevention strategies on ADE claims prevention. We conducted a retrospective analysis of a New England malpractice insurance company claims records from January 1, 1990, to December 31, 1999. Cases were electronically screened for possible ADEs and followed up by independent review of abstracts by 2 physician reviewers (T.K.G. and R.K.). Additional in-depth claims file reviews identified potential human factor failures associated with ADEs. Adverse drug events represented 6.3% (129/2040) of claims. Adverse drug events were judged preventable in 73% (n = 94) of the cases and were nearly evenly divided between outpatient and inpatient settings. The most frequently involved medication classes were antibiotics, antidepressants or antipsychotics, cardiovascular drugs, and anticoagulants. Among these ADEs, 46% were life threatening or fatal. System deficiencies and performance errors were the most frequent cause of preventable ADEs. The mean costs of defending malpractice claims due to ADEs were comparable for nonpreventable inpatient and outpatient ADEs and preventable outpatient ADEs (mean, $64,700-74,200), but costs were considerably greater for preventable inpatient ADEs (mean, $376,500). Adverse drug events associated with malpractice claims were often severe, costly, and preventable, and about half occurred in outpatients. Many interventions could potentially have prevented ADEs, with error proofing and process standardization covering the greatest proportion of events.
Clinical judicial syndrome: The impact of judicial proceedings on doctors.
Arimany-Manso, Josep; Vizcaíno, Marta; Gómez-Durán, Esperanza L
2018-04-28
Complaints of alleged malpractice are a concern for doctors, however the impact these complaints have on them receives little attention. We present a systematic review of the scientific literature by searching the MEDLINE database, without no time limit, of manuscripts on doctors' reaction to a malpractice claim, carried out in Spanish, English and French. Their methodological quality was evaluated, and the results were analysed. The search identified a total of 18 articles, mostly without empirical sample analysis, which described the clinical judicial syndrome construct, its symptomatology, prevalence, etiopathogenesis and issues of prevention and approach. The literature on this subject is very scarce and has poor empirical foundation. However, the available data underscored the relevance of the impact that these complaints have on doctors and highlight the need to establish preventive measures and approaches to the so-called clinical judicial syndrome.

Despite US sanitation advancements, millions of waterborne disease cases occur annually, although the precise burden of disease is not well quantified. Estimating the direct healthcare cost of specific infections would be useful in prioritizing waterborne disease prevention activities. Hospitalization and outpatient visit costs per case and total US hospitalization costs for ten waterborne diseases were calculated using large healthcare claims and hospital discharge databases. The five primarily waterborne diseases in this analysis (giardiasis, cryptosporidiosis, Legionnaires' disease, otitis externa, and non-tuberculous mycobacterial infection) were responsible for over 40 000 hospitalizations at a cost of $970 million per year, including at least $430 million in hospitalization costs for Medicaid and Medicare patients. An additional 50 000 hospitalizations for campylobacteriosis, salmonellosis, shigellosis, haemolytic uraemic syndrome, and toxoplasmosis cost $860 million annually ($390 million in payments for Medicaid and Medicare patients), a portion of which can be assumed to be due to waterborne transmission.
Voluntarism in early psychology: the case of Hermann von Helmholtz.
De Kock, Liesbet
2014-05-01
The failure to recognize the programmatic similarity between (post-)Kantian German philosophy and early psychology has impoverished psychology's historical self-understanding to a great extent. This article aims to contribute to recent efforts to overcome the gaps in the historiography of contemporary psychology, which are the result of an empiricist bias. To this end, we present an analysis of the way in which Hermann von Helmholtz's theory of perception resonates with Johann Gottlieb Fichte's Ego-doctrine. It will be argued that this indebtedness is particularly clear when focusing on the foundation of the differential awareness of subject and object in perception. In doing so, the widespread reception of Helmholtz's work as proto-positivist or strictly empiricist is challenged, in favor of the claim that important elements of his theorizing can only be understood properly against the background of Fichte's Ego-doctrine.

An estimation of the cost per visit of nursing home care services.
Ryu, Ho-Sihn
2009-01-01
Procedures used for analyzing the cost of providing home care nursing services through hospital-based home care agencies (HCAs) was the focus of this study. A cross-sectional descriptive study design was used to analyze the workload and caseload of 36 home care nurses from ten HCAs. In addition, information obtained from a national health insurance database, including 54,639 home care claim cases from a total of 185 HCAs during a 6-month period, were analyzed. The findings provide a foundation for improving the alternative home care billing and reimbursement system by using the actual amount of time invested in providing home care when calculating the cost of providing home care nursing services. Further, this study provides a procedure for calculating nursing service costs by analyzing actual data. The results have great potential for use in nursing service cost analysis methodology, which is an essential step in developing a policy for providing home care.

SUMMARY Despite US sanitation advancements, millions of waterborne disease cases occur annually, although the precise burden of disease is not well quantified. Estimating the direct healthcare cost of specific infections would be useful in prioritizing waterborne disease prevention activities. Hospitalization and outpatient visit costs per case and total US hospitalization costs for ten waterborne diseases were calculated using large healthcare claims and hospital discharge databases. The five primarily waterborne diseases in this analysis (giardiasis, cryptosporidiosis, Legionnaires’ disease, otitis externa, and non-tuberculous mycobacterial infection) were responsible for over 40 000 hospitalizations at a cost of $970 million per year, including at least $430 million in hospitalization costs for Medicaid and Medicare patients. An additional 50 000 hospitalizations for campylobacteriosis, salmonellosis, shigellosis, haemolytic uraemic syndrome, and toxoplasmosis cost $860 million annually ($390 million in payments for Medicaid and Medicare patients), a portion of which can be assumed to be due to waterborne transmission.

Australian consumers are sceptical about but influenced by claims about fat on food labels.
Chan, C; Patch, C; Williams, P
2005-01-01
To explore the beliefs and attitudes of Australian consumers to claims about fat made on the labels of packaged food. Content analysis of transcripts from focus group discussions. A total of 26 female and 10 male participants aged 20-80 y, recruited by advertisement into six focus groups, stratified by age, sex and health status. Awareness of claims about fat was high in this sample of Australians and participants admitted that they influenced their purchase decisions. The most preferred form of claim was 'X% fat free'. Claims were considered most useful on foods that were high in fat. There was considerable scepticism about all nutrient claims, and consumers preferred to check claims about fat against the values in the nutrition information panel. Many claims were seen as advertising that could be misleading, deceptive or confusing. While claims about fat might prompt product trial, factors such as price, taste, naturalness, as well as other nutritional factors, also influenced purchase decisions. Some consumers believe low fat claims encourage over consumption of foods. Changes to regulations governing nutrition claims on food labels should be made to enhance their credibility and support their role in assisting consumers to make healthier food choices.
Towards evidence-based management: creating an informative database of nursing-sensitive indicators.
Patrician, Patricia A; Loan, Lori; McCarthy, Mary; Brosch, Laura R; Davey, Kimberly S
2010-12-01
The purpose of this paper is to describe the creation, evolution, and implementation of a database of nursing-sensitive and potentially nursing-sensitive indicators, the Military Nursing Outcomes Database (MilNOD). It discusses data quality, utility, and lessons learned. Prospective data collected each shift include direct staff hours by levels (i.e., registered nurse, other licensed and unlicensed providers), staff categories (i.e., military, civilian, contract, and reservist), patient census, acuity, and admissions, discharges, and transfers. Retrospective adverse event data (falls, medication errors, and needle-stick injuries) were collected from existing records. Annual patient satisfaction, nurse work environment, and pressure ulcer and restraint prevalence surveys were conducted. The MilNOD contains shift level data from 56 units in 13 military hospitals and is used to target areas for managerial and clinical performance improvement. This methodology can be modified for use in other healthcare systems. As standard tools for evidence-based management, databases such as MilNOD allow nurse leaders to track the status of nursing and adverse events in their facilities.

Effect of loss control service on reported injury incidence.
Nave, Michael E; Veltri, Anthony
2004-01-01
A retrospective analysis evaluated the effectiveness of an insurance carrier's flexible loss control service strategy in reducing workers' compensation policyholders' reported injury and illness claims. To assess the effects of a loss control service strategy on workers' compensation claim frequency rates, on medical-only claim rates, on severity-claim rates, and on claim cost among a group of California employers. Eighty-two small- and medium-sized companies with workers' compensation policies expiring in 1999 were randomly selected from a population of policyholders assigned to loss control consultants for two or more years. Claim performance data were obtained for each company's first expired in-force policy year and its 1999 expired policy year. The retrospective design was combined with a control component based on a randomly selected comparison group of 45 companies whose first policy year with the insurer expired in 1999 and who received safety services from the loss control staff. The flexible loss control consultation service strategy was associated with lower average claim rates and costs. Companies assigned to a loss control consultant for two or more years (the "outcome group") had an average claim rate of 1.24 per $10,000 premium, compared with a rate of 1.62 in the "initial group" and a rate of 1.60 in the "comparison group." The average severity-claim rate of the outcome group was 0.32, compared with the initial-year and comparison-group means of 0.48 and 0.46, respectively. The average medical-only claim rate was 0.92, compared with the initial- and comparison-group means of 1.14 and 1.14. The outcome group's average loss ratio was over 10% lower than that of the initial and comparison groups. Statistical analysis indicated that differences among the groups' claim rates and severity-claim rates were [F=(2,206) 4.938, P=0.008] and [F=(2,206) 8.208, P<0.001], respectively. A loss control service strategy that provides service flexibility and develops partnership between employer and consultant can help reduce the frequency and severity of workers' compensation claims. Barriers to consultation service flexibility, both internal and external, should be identified and removed to enhance service efficacy.

Journal advertising is used by pharmaceutical companies to disseminate medicine information to doctors. The quality of claims, references and the presentation of risk results in Australia and the US has been questioned in several studies. No recent evidence is available on the quality of claims, references and the presentation of risk results in journal advertising in Australia and the US and no Malaysian data have been published. The aim of this study was to compare the quality of claims, references and the presentation of risk results in journal advertising in these three countries. A consecutive sample of 85 unique advertisements from each country was selected from journal advertising published between January 2004 to December 2006. Claims, references and the presentation of risk results in medical journal advertising were compared between the three countries. Less than one-third of the claims were unambiguous claims (Australia, 30%, Malaysia 17%, US, 23%). In Malaysia significantly less unambiguous claims were provided than in Australia and the US (P < 0.001). However, the unambiguous claims were supported by more references than other claims (80%). Most evidence was obtained from at least one randomized controlled trial, a systematic review or meta-analysis (Australia, 84%, Malaysia, 81%, US, 76%) with journal articles being the most commonly cited references in all countries. Data on file were significantly more likely to be cited in the US (17%) than in Australia (2%) and Malaysia (4%) (P < 0.001). Advertisements that provided quantitative information reported risk results exclusively as a relative risk reduction. The majority of claims were vague suggesting poor quality of claims in journal advertising in these three countries. Evidence from a randomized controlled trial, systematic review or meta- analysis was commonly cited to support claims. However, the more frequent use of data that have not been published and independently reviewed in the US compared to Australia and Malaysia raises questions on the quality of references in the US. The use of relative rather than absolute benefits may overemphasize the benefit of medicines which may leave doctors susceptible to misinterpreting information.

Thermal burn and electrical injuries among electric utility workers, 1995-2004.
Fordyce, Tiffani A; Kelsh, Michael; Lu, Elizabeth T; Sahl, Jack D; Yager, Janice W
2007-03-01
This study describes the occurrence of work-related injuries from thermal-, electrical- and chemical-burns among electric utility workers. We describe injury trends by occupation, body part injured, age, sex, and circumstances surrounding the injury. This analysis includes all thermal, electric, and chemical injuries included in the Electric Power Research Institute (EPRI) Occupational Health and Safety Database (OHSD). There were a total of 872 thermal burn and electric shock injuries representing 3.7% of all injuries, but accounting for nearly 13% of all medical claim costs, second only to the medical costs associated with sprain- and strain-related injuries (38% of all injuries). The majority of burns involved less than 1 day off of work. The head, hands, and other upper extremities were the body parts most frequently injured by burns or electric shocks. For this industry, electric-related burns accounted for the largest percentage of burn injuries, 399 injuries (45.8%), followed by thermal/heat burns, 345 injuries (39.6%), and chemical burns, 51 injuries (5.8%). These injuries also represented a disproportionate number of fatalities; of the 24 deaths recorded in the database, contact with electric current or with temperature extremes was the source of seven of the fatalities. High-risk occupations included welders, line workers, electricians, meter readers, mechanics, maintenance workers, and plant and equipment operators.

Tuberculosis screening is recommended for patients with immune-mediated inflammatory diseases (IMIDs) prior to anti-tumor necrosis factor (TNF) therapy. However, adherence to the recommended practice is unknown in the current clinical setting in Japan. We used a large-scale health insurance claims database in Japan to conduct a longitudinal observational study. Of more than two million beneficiaries in the database between 2013 and 2014, we enrolled those with IMIDs aged 15-69 years who had initiated anti-TNF therapy. We defined tuberculosis screening primarily as tuberculin skin test and/or interferon-gamma release assay (TST/IGRA) within 2 months before commencing anti-TNF therapy. We analyzed the proportions of the patients who had undergone tuberculosis screening and the associations with primary disease, type of anti-TNF agent, methotrexate prescription prior to anti-TNF therapy, and treatment for latent tuberculosis infection (LTBI). Of 385 patients presumed to have initiated anti-TNF therapy, 252 (66%) had undergone tuberculosis screening by TST/IGRA (22% TST, 56% IGRA, and 12% both TST and IGRA), and 231 (60%) had undergone TST/IGRA and radiography. Patients with psoriasis tended to be more likely to undergo tuberculosis screening than those with other diseases; however, this association was not statistically significant. Treatment for LTBI was provided to 43 (11%) patients; 123 (32%) received neither TST/IGRA nor LTBI treatment. Tuberculosis screening was often not performed prior to anti-TNF therapy despite the guidelines' recommendations; thus, patients could be put at unnecessary risk of reactivation of tuberculosis. © 2017 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.
The benefits of data linkage for firefighter injury surveillance.
Widman, Shannon A; LeVasseur, Michael T; Tabb, Loni P; Taylor, Jennifer A
2018-02-01
While survey data are available for national estimates of fire events and firefighter fatalities, data on firefighter injury at the national and local levels remain incomplete and unreliable. Data linkage provides a vehicle to maximise case detection and deepen injury description for the US fire service. By linking departmental Human Resources records, despatch data, workers' compensation and first reports of injury, researchers were able to describe reported non-fatal injuries to 3063 uniformed members of the Philadelphia Fire Department (PFD), for the period of 2005 through 2013. Among all four databases, the overall linkage rate was 56%. Among three of the four databases, the linkage rate was 88%. Because there was duplication of some variables among the datasets, we were able to deeply describe all the linked injuries in the master database. 45.5% of uniformed PFD members reported at least one injury during the study period. Strains, falls, burns and struck-by injuries were the most common causes. Burns resulted in the highest lost time claim payout, and strains accounted for the highest medical claim cost. More than 70% of injuries occurred in the first 15 years of experience. Data linkage provided three new benefits: (1) creation of a new variable-years of experience, (2) reduction of misclassification bias when determining cause of injury, leading to more accurate estimates of cost and (3) visualisation of injury rates when controlling for the number of fire department responses, allowing for the generation of hypotheses to investigate injury hot spots.

ABSTRACT The introduction of pertussis vaccination in the United States (US) in the 1940s has greatly reduced its burden. However, the incidence of pertussis is difficult to quantify, as many cases are not laboratory-confirmed or reported, particularly in adults. This study estimated pertussis incidence in a commercially insured US population aged <50 years. Data were extracted from IMS' PharMetrics Plus claims database for patients with a diagnosis of pertussis or cough illness using International Classification of Diseases (ICD-9) codes, a commercial outpatient laboratory database for patients with a pertussis laboratory test, and the Centers for Disease Control influenza surveillance database. US national pertussis incidence was projected using 3 methods: (1) diagnosed pertussis, defined as a claim for pertussis (ICD-9 033.0, 033.9, 484.3) during 2008–2013; (2) based on proxy pertussis predictive logistic regression models; (3) using the fraction of cough illness (ICD-9 033.0, 033.9, 484.3, 786.2, 466.0, 466.1, 487.1) attributed to laboratory-confirmed pertussis, estimated by time series linear regression models. Method 1 gave a projected annual incidence of diagnosed pertussis of 9/100,000, which was highest in those aged <1 year. Method 2 gave an average annual projected incidence of 21/100,000. Method 3 gave an overall regression-estimated weighted annual incidence of pertussis of 649/100,000, approximately 58–93 times higher than method 1 depending on the year. These estimations, which are consistent with considerable underreporting of pertussis in people aged <50 years and provide further evidence that the majority of cases go undetected, especially with increasing age, may aid in the development of public health programs to reduce pertussis burden.

On the connection of gamma-ray bursts and X-ray flashes in the BATSE and RHESSI databases

Řípa, J.; Mészáros, A.
2016-12-01
Classification of gamma-ray bursts (GRBs) into groups has been intensively studied by various statistical tests in previous years. It has been suggested that there was a distinct group of GRBs, beyond the long and short ones, with intermediate durations. However, such a group is not securely confirmed yet. Strangely, concerning the spectral hardness, the observations from the Swift and RHESSI satellites give different results. For the Swift/BAT database it is found that the intermediate-duration bursts might well be related to so-called X-ray flashes (XRFs). On the other hand, for the RHESSI dataset the intermediate-duration bursts seem to be spectrally too hard to be given by XRFs. The connection of the intermediate-duration bursts and XRFs for the BATSE database is not clear as well. The purpose of this article is to check the relation between XRFs and GRBs for the BATSE and RHESSI databases, respectively. We use an empirical definition of XRFs introduced by other authors earlier. For the RHESSI database we also use a transformation between the detected counts and the fluences based on the simulated detector response function. The purpose is to compare the hardnesses of GRBs with the definition of XRFs. There is a 1.3-4.2 % fraction of XRFs in the whole BATSE database. The vast majority of the BATSE short bursts are not XRFs because only 0.7-5.7 % of the short bursts can be given by XRFs. However, there is a large uncertainty in the fraction of XRFs among the intermediate-duration bursts. The fraction of 1-85 % of the BATSE intermediate-duration bursts can be related to XRFs. For the long bursts this fraction is between 1.0 % and 3.4 %. The uncertainties in these fractions are large, however it can be claimed that all BATSE intermediate-duration bursts cannot be given by XRFs. At least 79 % of RHESSI short bursts, at least 53 % of RHESSI intermediate-duration bursts, and at least 45 % of RHESSI long bursts should not be given by XRFs. A simulation of XRFs observed by HETE-2 and Swift has shown that RHESSI would detect, and in fact detected, only one long-duration XRF out of 26 ones observed by those two satellites. We arrive at the conclusion that the intermediate-duration bursts in the BATSE database can be partly populated by XRFs, but the RHESSI intermediate-duration bursts are most likely not given by XRFs. The results, claiming that the Swift/BAT intermediate-duration bursts are closely related to XRFs do not hold for the BATSE and RHESSI databases.

To determine the relationship between lifestyle variables including body mass index and filing a workers' compensation claim due to firefighter injury. A cross-sectional evaluation of firefighter injury related to workers" compensation claims occurring 5 years after the original Promoting Healthy Lifestyles: Alternative Models' Effects study intervention. A logistic regression analysis for variables predicting filing a workers' compensation claim due to an injury was performed with a total of 433 participants. The odds of filing a compensation claim were almost 3 times higher for firefighters with a body mass index of more than 30 kg/m than firefighters with a normal body mass index (odds ratio, 2.89; P < 0.05). This study addresses a high-priority area of reducing firefighter injuries and workers' compensation claims. Maintaining a healthy body weight is important to reduce injury and workers' compensation claims among firefighters.

The results of a NASA investigation of a claimed Overlap between two gust response analysis methods: the Statistical Discrete Gust (SDG) Method and the Power Spectral Density (PSD) Method are presented. The claim is that the ratio of an SDG response to the corresponding PSD response is 10.4. Analytical results presented for several different airplanes at several different flight conditions indicate that such an Overlap does appear to exist. However, the claim was not met precisely: a scatter of up to about 10 percent about the 10.4 factor can be expected.
Health and nutrition content claims on Australian fast-food websites.

2017-03-01
To determine the extent that Australian fast-food websites contain nutrition content and health claims, and whether these claims are compliant with the new provisions of the Australia New Zealand Food Standards Code ('the Code'). Systematic content analysis of all web pages to identify nutrition content and health claims. Nutrition information panels were used to determine whether products with claims met Nutrient Profiling Scoring Criteria (NPSC) and qualifying criteria, and to compare them with the Code to determine compliance. Australian websites of forty-four fast-food chains including meals, bakery, ice cream, beverage and salad chains. Any products marketed on the websites using health or nutrition content claims. Of the forty-four fast-food websites, twenty (45 %) had at least one claim. A total of 2094 claims were identified on 371 products, including 1515 nutrition content (72 %) and 579 health claims (28 %). Five fast-food products with health (5 %) and 157 products with nutrition content claims (43 %) did not meet the requirements of the Code to allow them to carry such claims. New provisions in the Code came into effect in January 2016 after a 3-year transition. Food regulatory agencies should review fast-food websites to ensure compliance with the qualifying criteria for nutrition content and health claim regulations. This would prevent consumers from viewing unhealthy foods as healthier choices. Healthy choices could be facilitated by applying NPSC to nutrition content claims. Fast-food chains should be educated on the requirements of the Code regarding claims.

Abstract Aim of the present paper is the review of the principal complications associated to endocrine neck surgery considering how expertise, full adoption of guidelines, appropriate technology and proper informed consent may limit the medicolegal claims at the light of the incoming new regulation of the medical professional legal responsibility. A literature search, using the Medline/PubMed database for full-length papers, was used. Postoperative recurrent laryngeal nerve (RLN) palsy and hypoparathy-roidism remain the principal causes of surgical malpractice claims . In the procedure of neck lymphadenctomy intra-operative haemorrhage, thoracic duct injury, injuries to loco-regional nerves can be observed and can be source of claims. After many years of increased medicolegal litigations, the Italian government is proposing a drastic change in the regulations of supposed medical malpractice in order to guarantee the patient’s right to a safe treatment and in the meantime to defend clinicians from often unmotivated and prejudicial legal cases. Surgical errors and complications in neck surgery are a relevant clinical issue. Only the combination of surgical and clinical expertise, application of guidelines, appropriate technology and a routinely use of specific informed consent can contain potential medicolegal implications.

Musculoskeletal injury exerts a significant burden on US industry. The purpose of this study was to investigate the frequency and characteristics of musculoskeletal injuries in the California (CA) film and motion picture (FMP) industry which may result in unforeseen morbidity and mortality. We reviewed the workers' compensation (WC) claims database of the Workers' Compensation Insurance Rating Bureau of California (WCIRB) and employment statistics through the US Bureau of Labor Statistics (BLS). We analyzed the frequency, type, body part affected, and cause of musculoskeletal injuries. From 2003 to 2009, there were 3505 WC claims of which 94.4% were musculoskeletal. In the CA FMP industry, the most common injuries were strains (38.4%), sprains (12.2%), and fractures (11.7%). The most common sites of isolated injury were the knee (18.9%), lower back (15.0%), and ankle (8.6%). Isolated musculoskeletal spine injuries represented 19.3% of all injuries. The most common causes of injury were work-directed activity (36.0%) and falls (25.5%). We present the first report on the unique profile of musculoskeletal injury claims in the FMP industry. This data provides direction for improvement of workplace safety.

Sodium-related claims on food labels should facilitate lower-sodium food choices; however, consumer attitudes and understanding of such claims are unknown. We evaluated consumer attitudes and understanding of different types of sodium claims and the effect of having hypertension on responses to such claims. Canadian consumers (n = 506), with and without hypertension, completed an online survey that contained a randomized mock-package experiment, which tested 4 packages that differed only by the claims they carried as follows: 3 sodium claims (disease risk reduction, function, and nutrient-content claims) and a tastes-great claim (control). Participants answered the same questions on attitudes and understanding of claims after seeing each package. Food packages with any sodium claim resulted in more positive attitudes toward the claim and the product healthfulness than did packages with the taste control claim, although all mock packages were identical nutritionally. Having hypertension increased ratings related to product healthfulness and purchase intentions, but there was no difference in reported understanding between hypertensives and normotensives. In general, participants attributed additional health benefits to low-sodium products beyond the well-established relation of sodium and hypertension. Sodium claims have the potential to facilitate lower-sodium food choices. However, we caution that consumers do not seem to differentiate between different types of claims, but the nutritional profiles of foods that carry different sodium claims can potentially differ greatly in the current labeling environment. Additional educational efforts are needed to ensure that consumers do not attribute inappropriate health benefits to foods with low-sodium claims. This trial was registered at clinicaltrials.gov as NCT01764724.

In 2014, an estimated 2,477 children aged <13 years were living with diagnosed human immunodeficiency virus (HIV) infection in the United States (1). Nationally, little is known about how well children with a diagnosis of HIV infection are retained in medical care. CDC analyzed insurance claims data to evaluate retention in medical care for children in the United States with a diagnosis of HIV infection. Data sources were the 2010-2014 MarketScan Multi-State Medicaid and MarketScan Commercial Claims and Encounters databases. Children aged <13 years with a diagnosis of HIV infection in 2010 were identified using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic billing codes for HIV or acquired immunodeficiency syndrome (AIDS), resulting in Medicaid and commercial claims cohorts of 163 and 129 children, respectively. Data for each child were evaluated during a 36-month study period, counted from the date of the first claim containing an ICD-9-CM code for HIV or AIDS. Each child's consistency of medical care was assessed by evaluating the frequency of medical visits during the first 24 months of the study period to see if the frequency of visits met the definition of retention in care. Frequency of medical visits was then assessed during an additional 12-month follow-up period to evaluate differences in medical care consistency between children who were retained or not retained in care during the initial 24-month period. During months 0-24, 60% of the Medicaid cohort and 69% of the commercial claims cohort were retained in care, among whom 93% (Medicaid) and 85% (commercial claims) were in care during months 25-36. To identify areas for additional public health action, further evaluation of the objectives for national medical care for children with diagnosed HIV infection is indicated.

Despite several studies that have estimated the economic impact of Respiratory Syncytial Virus (RSV) in infants, limited data are available on healthcare resource use and costs attributable to RSV across age groups. The aim of this study was to quantify age-specific RSV-related healthcare resource use and costs on the US healthcare system. This retrospective case-control study identified patients aged ≥1 year with an RSV event in the Truven Health Marketscan® Commercial Claims and Encounters and Medicare Supplemental and Coordination of Benefits databases between August 31, 2012 and August 1, 2013. RSV patients were matched 1:1 with non-RSV controls for age, gender, region, healthcare plan and index date (n = 11,432 in each group). Stratified analyses for healthcare resource use and costs were conducted by age groups. RSV-attributable resource use and costs were assessed based on the incremental differences between RSV cases and controls using multivariate analysis. RSV patients had a higher healthcare resource use (hospital stays, emergency room/urgent care visits, ambulatory visits and outpatient visits) than non-RSV matched controls for all age groups (all p < 0.0001), particularly in the elderly age groups with RSV (1.9 to 3 days length of stay, 0.4 to 0.5 more ER/UC visits, 0.7 to 2.7 more ambulatory visits, 12.1 to 18.6 more outpatient visits and 9.5 to 14.6 more prescriptions than elderly in the control groups). The incremental difference in adjusted mean annual costs between RSV and non-RSV controls was higher in elderly (≥65; $12,030 to $23,194) than in those aged < 65 years ($2251 to $5391). Among children, adjusted costs attributable to RSV were higher in children aged 5-17 years ($3192), than those 1-4 years ($2251 to $2521). Our findings showed a substantial annual RSV-attributable healthcare resource use and costs in the US across age groups, with the highest burden in those aged ≥65 years. These data can be used in cost-effectiveness analyses, and may be useful for policymakers to guide future RSV vaccination and other prevention programs.

Administrative claims of United States Centers for Medicare and Medicaid Services (CMS) beneficiaries have long been used in non-experimental research. While CMS performs in-house checks of these claims, little is known of their quality for conducting pharmacoepidemiologic research. We performed exploratory analyses of the quality of Medicaid and Medicare data obtained from CMS and its contractors. Our study population consisted of Medicaid beneficiaries (with and without dual coverage by Medicare) from California, Florida, New York, Ohio, and Pennsylvania. We obtained and compiled 1999-2011 data from these state Medicaid programs (constituting about 38% of nationwide Medicaid enrollment), together with corresponding national Medicare data for dually-enrolled beneficiaries. This descriptive study examined longitudinal patterns in: dispensed prescriptions by state, by quarter; and inpatient hospitalizations by federal benefit, state, and age group. We further examined discrepancies between demographic characteristics and disease states, in particular frequencies of pregnancy complications among men and women beyond childbearing age, and prostate cancers among women. Dispensed prescriptions generally increased steadily and consistently over time, suggesting that these claims may be complete. A commercially-available National Drug Code lookup database was able to identify the dispensed drug for 95.2-99.4% of these claims. Because of co-coverage by Medicare, Medicaid data appeared to miss a substantial number of hospitalizations among beneficiaries ≥ 45 years of age. Pregnancy complication diagnoses were rare in males and in females ≥ 60 years of age, and prostate cancer diagnoses were rare in females. CMS claims from five large states obtained directly from CMS and its contractors appeared to be of high quality. Researchers using Medicaid data to study hospital outcomes should obtain supplemental Medicare data on dual enrollees, even for non-elders. Not applicable.

BACKGROUND: Claims-based measures of “low-value” pediatric services could facilitate the implementation of interventions to reduce the provision of potentially harmful services to children. However, few such measures have been developed. METHODS: We developed claims-based measures of 20 services that typically do not improve child health according to evidence-based guidelines (eg, cough and cold medicines). Using these measures and claims from 4.4 million commercially insured US children in the 2014 Truven MarketScan Commercial Claims and Encounters database, we calculated the proportion of children who received at least 1 low-value pediatric service during the year, as well as total and out-of-pocket spending on these services. We report estimates based on "narrow" measures designed to only capture instances of service use that were low-value. To assess the sensitivity of results to measure specification, we also reported estimates based on "broad measures" designed to capture most instances of service use that were low-value. RESULTS: According to the narrow measures, 9.6% of children in our sample received at least 1 of the 20 low-value services during the year, resulting in $27.0 million in spending, of which $9.2 million was paid out-of-pocket (33.9%). According to the broad measures, 14.0% of children in our sample received at least 1 of the 20 low-value services during the year. CONCLUSIONS: According to a novel set of claims-based measures, at least 1 in 10 children in our sample received low-value pediatric services during 2014. Estimates of low-value pediatric service use may vary substantially with measure specification. PMID:27940698
