    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.

    Large electronic healthcare databases have become an important worldwide data resource for drug safety research after approval. Signal generation methods and drug safety studies based on these data facilitate the prospective monitoring of drug safety after approval, as has been recently required by EU law and the German Medicines Act. Despite its large size, a single healthcare database may include insufficient patients for the study of a very small number of drug-exposed patients or the investigation of very rare drug risks. For that reason, in the United States, efforts have been made to work on models that provide the linkage of data from different electronic healthcare databases for monitoring the safety of medicines after authorization in (i) the Sentinel Initiative and (ii) the Observational Medical Outcomes Partnership (OMOP). In July 2014, the pilot project Mini-Sentinel included a total of 178 million people from 18 different US databases. The merging of the data is based on a distributed data network with a common data model. In the European Network of Centres for Pharmacoepidemiology and Pharmacovigilance (ENCEPP) there has been no comparable merging of data from different databases; however, first experiences have been gained in various EU drug safety projects. In Germany, the data of the statutory health insurance providers constitute the most important resource for establishing a large healthcare database. Their use for this purpose has so far been severely restricted by the Code of Social Law (Section 75, Book 10). Therefore, a reform of this section is absolutely necessary.

    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.

    Observational studies compare outcomes among subjects with and without an exposure of interest, without intervention from study investigators. Observational studies can be designed as a prospective or retrospective cohort study or as a case-control study. In healthcare epidemiology, these observational studies often take advantage of existing healthcare databases, making them more cost-effective than clinical trials and allowing analyses of rare outcomes. This paper addresses the importance of selecting a well-defined study population, highlights key considerations for study design, and offers potential solutions including biostatistical tools that are applicable to observational study designs.

    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.

    Defining a study population and creating an analytic dataset from longitudinal healthcare databases involves many decisions. Our objective was to catalogue scientific decisions underpinning study execution that should be reported to facilitate replication and enable assessment of validity of studies conducted in large healthcare databases. We reviewed key investigator decisions required to operate a sample of macros and software tools designed to create and analyze analytic cohorts from longitudinal streams of healthcare data. A panel of academic, regulatory, and industry experts in healthcare database analytics discussed and added to this list. Evidence generated from large healthcare encounter and reimbursement databases is increasingly being sought by decision-makers. Varied terminology is used around the world for the same concepts. Agreeing on terminology and which parameters from a large catalogue are the most essential to report for replicable research would improve transparency and facilitate assessment of validity. At a minimum, reporting for a database study should provide clarity regarding operational definitions for key temporal anchors and their relation to each other when creating the analytic dataset, accompanied by an attrition table and a design diagram. A substantial improvement in reproducibility, rigor and confidence in real world evidence generated from healthcare databases could be achieved with greater transparency about operational study parameters used to create analytic datasets from longitudinal healthcare databases. © 2017 The Authors.

    Many healthcare leaders find themselves overwhelmed with data, but lack the information they need to make informed decisions. Knowledge discovery in databases (KDD) can help organizations turn their data into information. KDD is the process of finding complex patterns and relationships in data. The tools and techniques of KDD have achieved impressive results in other industries, and healthcare needs to take advantage of advances in this exciting field. Recent advances in the KDD field have brought it from the realm of research institutions and large corporations to many smaller companies. Software and hardware advances enable small organizations to tap the power of KDD using desktop PCs. KDD has been used extensively for fraud detection and focused marketing. There is a wealth of data available within the healthcare industry that would benefit from the application of KDD tools and techniques. Providers and payers have a vast quantity of data (such as, charges and claims), but not effective way to analyze the data to accurately determine relationships and trends. Organizations that take advantage of KDD techniques will find that they offer valuable assistance in the quest to lower healthcare costs while improving healthcare quality.

    The aim of this study was to describe a number of electronic healthcare databases in Europe in terms of the population covered, the source of the data captured and the availability of data on key variables required for evaluating medicine use and medicine safety during pregnancy. A sample of electronic healthcare databases that captured pregnancies and prescription data was selected on the basis of contacts within the EUROCAT network. For each participating database, a database inventory was completed. Eight databases were included, and the total population covered was 25 million. All databases recorded live births, seven captured stillbirths and five had full data available on spontaneous pregnancy losses and induced terminations. In six databases, data were usually available to determine the date of the woman's last menstrual period, whereas in the remainder, algorithms were needed to establish a best estimate for at least some pregnancies. In seven databases, it was possible to use data recorded in the databases to identify pregnancies where the offspring had a congenital anomaly. Information on confounding variables was more commonly available in databases capturing data recorded by primary-care practitioners. All databases captured maternal co-prescribing and a measure of socioeconomic status. This study suggests that within Europe, electronic healthcare databases may be valuable sources of data for evaluating medicine use and safety during pregnancy. The suitability of a particular database, however, will depend on the research question, the type of medicine to be evaluated, the prevalence of its use and any adverse outcomes of interest. © 2014 The Authors.

    Healthcare databases are useful sources to investigate the epidemiology of chronic obstructive pulmonary disease (COPD), to assess longitudinal outcomes in patients with COPD, and to develop disease management strategies. However, in order to constitute a reliable source for research, healthcare databases need to be validated. The aim of this protocol is to perform the first systematic review of studies reporting the validation of codes related to COPD diagnoses in healthcare databases. MEDLINE, EMBASE, Web of Science and the Cochrane Library databases will be searched using appropriate search strategies. Studies that evaluated the validity of COPD codes (such as the International Classification of Diseases 9th Revision and 10th Revision system; the Real codes system or the International Classification of Primary Care) in healthcare databases will be included. Inclusion criteria will be: (1) the presence of a reference standard case definition for COPD; (2) the presence of at least one test measure (eg, sensitivity, positive predictive values, etc); and (3) the use of a healthcare database (including administrative claims databases, electronic healthcare databases or COPD registries) as a data source. Pairs of reviewers will independently abstract data using standardised forms and will assess quality using a checklist based on the Standards for Reporting of Diagnostic accuracy (STARD) criteria. This systematic review protocol has been produced in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P) 2015 statement. Ethics approval is not required. Results of this study will be submitted to a peer-reviewed journal for publication. The results from this systematic review will be used for outcome research on COPD and will serve as a guide to identify appropriate case definitions of COPD, and reference standards, for researchers involved in validating healthcare databases.

    There is an increasing reliance on databases of healthcare records for pharmacoepidemiology and other medical research, and such resources are often accessed over a long period of time so it is vital to consider the impact of changes in data, access methodology and the environment. The authors discuss change in communication and management, and provide a checklist of issues to consider for both database providers and users. The scope of the paper is database research, and changes are considered in relation to the three main components of database research: the data content itself, how it is accessed, and the support and tools needed to use the database.

    Park, Yubin; Shankar, Mallikarjun; Park, Byung H.

    Designing a database system for both efficient data management and data services has been one of the enduring challenges in the healthcare domain. In many healthcare systems, data services and data management are often viewed as two orthogonal tasks; data services refer to retrieval and analytic queries such as search, joins, statistical data extraction, and simple data mining algorithms, while data management refers to building error-tolerant and non-redundant database systems. The gap between service and management has resulted in rigid database systems and schemas that do not support effective analytics. We compose a rich graph structure from an abstracted healthcaremore » RDBMS to illustrate how we can fill this gap in practice. We show how a healthcare graph can be automatically constructed from a normalized relational database using the proposed 3NF Equivalent Graph (3EG) transformation.We discuss a set of real world graph queries such as finding self-referrals, shared providers, and collaborative filtering, and evaluate their performance over a relational database and its 3EG-transformed graph. Experimental results show that the graph representation serves as multiple de-normalized tables, thus reducing complexity in a database and enhancing data accessibility of users. Based on this finding, we propose an ensemble framework of databases for healthcare applications.« less

    An effectively designed e-healthcare system can significantly enhance the quality of access and experience of healthcare users, including facilitating medical and healthcare providers in ensuring a smooth delivery of services. Ensuring the security of patients' electronic health records (EHRs) in the e-healthcare system is an active research area. EHRs may be outsourced to a third-party, such as a community healthcare cloud service provider for storage due to cost-saving measures. Generally, encrypting the EHRs when they are stored in the system (i.e. data-at-rest) or prior to outsourcing the data is used to ensure data confidentiality. Searchable encryption (SE) scheme is a promising technique that can ensure the protection of private information without compromising on performance. In this paper, we propose a novel framework for controlling access to EHRs stored in semi-trusted cloud servers (e.g. a private cloud or a community cloud). To achieve fine-grained access control for EHRs, we leverage the ciphertext-policy attribute-based encryption (CP-ABE) technique to encrypt tables published by hospitals, including patients' EHRs, and the table is stored in the database with the primary key being the patient's unique identity. Our framework can enable different users with different privileges to search on different database fields. Differ from previous attempts to secure outsourcing of data, we emphasize the control of the searches of the fields within the database. We demonstrate the utility of the scheme by evaluating the scheme using datasets from the University of California, Irvine.

    Food composition tables and databases (FCTs or FCDBs) provide the necessary information to estimate intake of nutrients and other food components. In Spain, the lack of a reference database has resulted in use of different FCTs/FCDBs in nutritional surveys and research studies, as well as for development of dietetic for diet analysis. As a result, biased, non-comparable results are obtained, and healthcare professionals are rarely aware of these limitations. AECOSAN and the BEDCA association developed a FCDB following European standards, the Spanish Food Composition Database Network (RedBEDCA).The current database has a limited number of foods and food components and barely contains processed foods, which limits its use in epidemiological studies and in the daily practice of healthcare professionals.

    The strategic importance of healthcare research institutes (HRIs) in health sciences research in Spain has motivated this analysis of the feasibility of studing their contribution to the Spanish scientific output through their presence as a signatory institution in the publications. We identified the output of the HRIs in the Web of Science database, comparing their observed output (the institutes are explicitly listed in the authors' workplace) and potential output (estimated based on the linked hospitals). The studies based on scientific publications do not help us reliably identify the contribution of the HRIs because their observed production is much lower than the potential output, although their visibility tends to increase over time. This article highlights the importance of HRI members including the institute among their work addresses to increase the visibility of these organisations and to facilitate studies aimed at assessing their activity in the national and international context.

    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.

    Several authors have developed and applied methods to routine data sets to identify the nature and rate of complications following interventional procedures. But, to date, there has been no systematic search for such methods. The objective of this article was to find, classify and appraise published methods, based on analysis of clinical codes, which used routine healthcare databases in a United Kingdom setting to identify complications resulting from interventional procedures. A literature search strategy was developed to identify published studies that referred, in the title or abstract, to the name or acronym of a known routine healthcare database and to complications from procedures or devices. The following data sources were searched in February and March 2013: Cochrane Methods Register, Conference Proceedings Citation Index - Science, Econlit, EMBASE, Health Management Information Consortium, Health Technology Assessment database, MathSciNet, MEDLINE, MEDLINE in-process, OAIster, OpenGrey, Science Citation Index Expanded and ScienceDirect. Of the eligible papers, those which reported methods using clinical coding were classified and summarised in tabular form using the following headings: routine healthcare database; medical speciality; method for identifying complications; length of follow-up; method of recording comorbidity. The benefits and limitations of each approach were assessed. From 3688 papers identified from the literature search, 44 reported the use of clinical codes to identify complications, from which four distinct methods were identified: 1) searching the index admission for specified clinical codes, 2) searching a sequence of admissions for specified clinical codes, 3) searching for specified clinical codes for complications from procedures and devices within the International Classification of Diseases 10th revision (ICD-10) coding scheme which is the methodology recommended by NHS Classification Service, and 4) conducting manual clinical

    We present a World-Wide-Web-accessible database of astronomical images which suffer from a variety of observational problems. These problems range from common phenomena, such as dust grains on filters and/or dewar window, to more exotic cases like, for instance, deflated support airbags underneath the primary mirror. The purpose of this database is to enable astronomers at telescopes to save telescope time by discovering the nature of the trouble they might be experiencing with the help of this online catalog. Every observational mishap contained in this collection is presented in the form of a GIF image, a brief explanation of the problem, and, to the extent possible, a suggestion of what might be done to solve the problem and improve the image quality.

    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.

    The Mobile Source Observation Database (MSOD) is a relational database being developed by the Assessment and Standards Division (ASD) of the US Environmental Protection Agency Office of Transportation and Air Quality (formerly the Office of Mobile Sources). The MSOD contains emission test data from in-use mobile air- pollution sources such as cars, trucks, and engines from trucks and nonroad vehicles. Data in the database was collected from 1982 to the present. The data is intended to be representative of in-use vehicle emissions in the United States.

    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.

    Signal detection from healthcare databases is possible, but is not yet used for routine surveillance of drug safety. One challenge is to develop methods for selecting signals that should be assessed with priority. The aim of this study was to develop an automated system combining safety signal detection and prioritization from healthcare databases and applicable to drugs used in chronic diseases. Patients present in the French EGB healthcare database for at least 1 year between 2005 and 2015 were considered. Noninsulin glucose-lowering drugs (NIGLDs) were selected as a case study, and hospitalization data were used to select important medical events (IME). Signal detection was performed quarterly from 2008 to 2015 using sequence symmetry analysis. NIGLD/IME associations were screened if one or more exposed case was identified in the quarter, and three or more exposed cases were identified in the population at the date of screening. Detected signals were prioritized using the Longitudinal-SNIP (L-SNIP) algorithm based on strength (S), novelty (N), and potential impact of signal (I), and pattern of drug use (P). Signals scored in the top 10% were identified as of high priority. A reference set was built based on NIGLD summaries of product characteristics (SPCs) to compute the performance of the developed system. A total of 815 associations were screened and 241 (29.6%) were detected as signals; among these, 58 (24.1%) were prioritized. The performance for signal detection was sensitivity = 47%; specificity = 80%; positive predictive value (PPV) 33%; negative predictive value = 82%. The use of the L-SNIP algorithm increased the early identification of positive controls, restricted to those mentioned in the SPCs after 2008: PPV = 100% versus PPV = 14% with its non-use. The system revealed a strong new signal with dipeptidylpeptidase-4 inhibitors and venous thromboembolism. The developed system seems promising for the routine use of healthcare data for safety

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].

    Chronic kidney disease (CKD) progression is associated with significant comorbidities and costs. In Italy, limited evidence of healthcare resource consumption and costs is available. We therefore aimed to investigate the direct healthcare costs in charge to the Lombardy Regional Health Service (RHS) for the treatment of CKD patients in the first year after starting hemodialysis and in the 2 years prior to dialysis. Citizens resident in the Lombardy Region (Italy) who initiated dialysis in the year 2011 (Jan 1 to Dec 31) were selected and data were extracted from Lombardy Regional databases on their direct healthcare costs in the first year after starting dialysis and in the 2 years prior to it was analyzed. Drugs, hospitalizations, diagnostic procedures and outpatient costs covered by RHS were estimated. Patients treated for acute kidney injury, or who died or stopped dialysis during the observational period were excluded. From the regional population (>9,700,000 inhabitants), 1067 patients (34.3 % females) initiating dialysis were identified, of whom 82 % underwent only hemodialysis (HD), 13 % only peritoneal dialysis (PD) and the remaining 5 % both treatments. Direct healthcare costs/patient were € 5239, € 12,303 and € 38,821 (€ 40,132 for HD vs. € 30,444 for PD patients) for the periods 24-12 months pre-dialysis, 12-0 months pre-dialysis, and in the first year of dialysis, respectively. This study highlights a significant economic burden related to CKD and an increase in direct healthcare costs associated with the start of dialysis, pointing to the importance of prevention programs and early diagnosis.

    Objective Estimates of treatment effectiveness in epidemiologic studies using large observational health care databases may be biased due to inaccurate or incomplete information on important confounders. Study methods that collect and incorporate more comprehensive confounder data on a validation cohort may reduce confounding bias. Study Design and Setting We applied two such methods, imputation and reweighting, to Group Health administrative data (full sample) supplemented by more detailed confounder data from the Adult Changes in Thought study (validation sample). We used influenza vaccination effectiveness (with an unexposed comparator group) as an example and evaluated each method’s ability to reduce bias using the control time period prior to influenza circulation. Results Both methods reduced, but did not completely eliminate, the bias compared with traditional effectiveness estimates that do not utilize the validation sample confounders. Conclusion Although these results support the use of validation sampling methods to improve the accuracy of comparative effectiveness findings from healthcare database studies, they also illustrate that the success of such methods depends on many factors, including the ability to measure important confounders in a representative and large enough validation sample, the comparability of the full sample and validation sample, and the accuracy with which data can be imputed or reweighted using the additional validation sample information.

    Pregnancy prevention programmes (PPPs) exist for some medicines known to be highly teratogenic. It is increasingly recognised that the impact of these risk minimisation measures requires periodic evaluation. This study aimed to assess the extent to which some of the data needed to monitor the effectiveness of PPPs may be present in European healthcare databases. An inventory was completed for databases contributing to EUROmediCAT capturing pregnancy and prescription data in Denmark, Norway, the Netherlands, Italy (Tuscany/Emilia Romagna), Wales and the rest of the UK, to determine the extent of data collected that could be used to evaluate the impact of PPPs. Data availability varied between databases. All databases could be used to identify the frequency and duration of prescriptions to women of childbearing age from primary care, but there were specific issues with availability of data from secondary care and private care. To estimate the frequency of exposed pregnancies, all databases could be linked to pregnancy data, but the accuracy of timing of the start of pregnancy was variable, and data on pregnancies ending in induced abortions were often not available. Data availability on contraception to estimate compliance with contraception requirements was variable and no data were available on pregnancy tests. Current electronic healthcare databases do not contain all the data necessary to fully monitor the effectiveness of PPP implementation, and thus, special data collection measures need to be instituted.

    Heavy menstrual bleeding (HMB) is a highly prevalent condition, characterized by excessive menstrual blood loss and cramping, that interferes with activities of daily life. The aim of this study was to investigate treatment patterns in HMB in Japan, and to assess healthcare resource utilization and costs among women newly-diagnosed with the condition. This study retrospectively analyzed health insurance data available in the Japan Medical Data Center (JMDC) database on women aged 18-49 years who were newly-diagnosed with primary or secondary HMB. Treatment patterns were analyzed, and healthcare utilization and costs were evaluated and compared to matched controls. The study included a total of 635 patients, 210 with primary HMB and 425 with secondary HMB. In the primary HMB cohort, 60.0% of patients received one or more pharmacological or surgical treatments, compared with 76.2% in the secondary HMB cohort. The most commonly prescribed medications in all patients were hemostatic agents (28.7%), traditional Chinese medicine (TCM) (12.1%), and low-dose estrogen progestins (LEPs) (10.1%). After adjustment for patient baseline characteristics, healthcare costs were 1.93-times higher in primary HMB cases (p < .0001) and 4.44-times higher in secondary HMB cases (p < .0001) vs healthy controls. Outpatient care was the main cost driver. The main limitations of this study are related to its retrospective nature, and the fact that only reimbursed medications were captured in the source database. A substantial proportion of HMB patients did not receive the recommended treatments. Healthcare costs were considerably increased in the presence of an HMB diagnosis.

    Quality management is necessary for establishing useful clinical database in cooperation with healthcare professionals and facilities. The ways of management are 1) progress management of data entry, 2) liaison with database participants (healthcare professionals), and 3) modification of data collection form. In addition, healthcare facilities are supposed to consider ethical issues and information security for joining clinical databases. Database participants should check ethical review boards and consultation service for patients.

    to assess the role of four administrative healthcare databases (pathology reports, copayment exemptions, hospital discharge records, gluten-free food prescriptions) for the identification of possible paediatric cases of celiac disease. population-based observational study with record linkage of administrative healthcare databases. SETTING AND PARTICIPANT S: children born alive in the Friuli Venezia Giulia Region (Northern Italy) to resident mothers in the years 1989-2012, identified using the regional Medical Birth Register. we defined possible celiac disease as having at least one of the following, from 2002 onward: 1. a pathology report of intestinal villous atrophy; 2. a copayment exemption for celiac disease; 3. a hospital discharge record with ICD-9-CM code of celiac disease; 4. a gluten-free food prescription. We evaluated the proportion of subjects identified by each archive and by combinations of archives, and examined the temporal relationship of the different sources in cases identified by more than one source. RESULT S: out of 962 possible cases of celiac disease, 660 (68.6%) had a pathology report, 714 (74.2%) a copayment exemption, 667 (69.3%) a hospital discharge record, and 636 (66.1%) a gluten-free food prescription. The four sources coexisted in 42.2% of subjects, whereas 30.2% were identified by two or three sources and 27.6% by a single source (16.9% by pathology reports, 4.2% by hospital discharge records, 3.9% by copayment exemptions, and 2.6% by gluten-free food prescriptions). Excluding pathology reports, 70.6% of cases were identified by at least two sources. A definition based on copayment exemptions and discharge records traced 80.5% of the 962 possible cases of celiac disease; whereas a definition based on copayment exemptions, discharge records, and gluten-free food prescriptions traced 83.1% of those cases. The temporal relationship of the different sources was compatible with the typical diagnostic pathway of subjects with celiac

    Medication management is a complex, error-prone process. The aim of this study was to explore what constitutes the complexity of the medication management process (MMP) in specialized home healthcare and how healthcare professionals handle this complexity. The study is theoretically based in resilience engineering. Data were collected during the MMP at three specialized home healthcare units in Sweden using two strategies: observation of workplaces and shadowing RNs in everyday work, including interviews. Transcribed material was analysed using grounded theory. The MMP in home healthcare was dynamic and complex with unclear boundaries of responsibilities, inadequate information systems and fluctuating work conditions. Healthcare professionals adapted their everyday clinical work by sharing responsibility and simultaneously being authoritative and preserving patients' active participation, autonomy and integrity. To promote a safe MMP, healthcare professionals constantly re-prioritized goals, handled gaps in communication and information transmission at a distance by creating new bridging solutions. Trade-offs and workarounds were necessary elements, but also posed a threat to patient safety, as these interim solutions were not systematically evaluated or devised learning strategies. To manage a safe medication process in home healthcare, healthcare professionals need to adapt to fluctuating conditions and create bridging strategies through multiple parallel activities distributed over time, space and actors. The healthcare professionals' strategies could be integrated in continuous learning, while preserving boundaries of safety, instead of being more or less interim solutions. Patients' and family caregivers' as active partners in the MMP may be an underestimated resource for a resilient home healthcare.

    2012-07-01

    This paper reports work from a Centre for Interprofessional Practice in a higher education institution in the UK that offers four levels of interprofessional learning (IPL) to all healthcare students. The second level (IPL2) integrates professional practice into the learning process, requiring students to shadow a qualified healthcare professional (from a different profession) for half a day. Students complete a reflective statement upon their learning experience on their return. A study was undertaken to analyse students' reflective statements in depth to see their observations and reflections on the shadowing visit. Using frame analysis, 160 reflective statements were analyzed, identifying common words and phrases used by students, which were then grouped together under six themes. Three of these related directly to the assignment: communication styles and techniques; communication between healthcare professionals and comparison of students' own and other healthcare professionals' roles. Three themes emerged from student's own interpretation of observations and reflections made during the shadowing of a different professional: attitudes toward other professions; power structures between professionals and patients and between professionals and impact of communication on patient care. Interprofessional shadowing gives students an opportunity to observe communication between healthcare professionals and patients and to reflect on broader issues surrounding collaborative working.

    Background: Utilization of the available observational healthcare datasets is key to complement and strengthen the postmarketing safety studies. Use of common data models (CDM) is the predominant approach in order to enable large scale systematic analyses on disparate data models and vocabularies. Current CDM transformation practices depend on proprietarily developed Extract-Transform-Load (ETL) procedures, which require knowledge both on the semantics and technical characteristics of the source datasets and target CDM. Purpose: In this study, our aim is to develop a modular but coordinated transformation approach in order to separate semantic and technical steps of transformation processes, which do not have a strict separation in traditional ETL approaches. Such an approach would discretize the operations to extract data from source electronic health record systems, alignment of the source, and target models on the semantic level and the operations to populate target common data repositories. Approach: In order to separate the activities that are required to transform heterogeneous data sources to a target CDM, we introduce a semantic transformation approach composed of three steps: (1) transformation of source datasets to Resource Description Framework (RDF) format, (2) application of semantic conversion rules to get the data as instances of ontological model of the target CDM, and (3) population of repositories, which comply with the specifications of the CDM, by processing the RDF instances from step 2. The proposed approach has been implemented on real healthcare settings where Observational Medical Outcomes Partnership (OMOP) CDM has been chosen as the common data model and a comprehensive comparative analysis between the native and transformed data has been conducted. Results: Health records of ~1 million patients have been successfully transformed to an OMOP CDM based database from the source database. Descriptive statistics obtained from the source and

    Administrative healthcare utilization databases are frequently used either individually or as a component of aggregated data for evaluating drug safety issues without taking into account their known deficiencies. All too often insufficient evidence is provided about their validity for the purposes for which they are used. The assessment of data validity is a key constituent that should be included in drug safety research studies and should take a broad multifaceted approach that encompasses both diagnostic and drug exposure data. Drug safety researchers need to continue advancing their knowledge of the data resources they use and to ensure that they and the users of their research understand the limitations of the data that are the foundation on which their research is built. Fundamental issues regarding data validity should be addressed in each use of administrative data for drug safety research.

    Clinical studies that use observational databases to evaluate the effects of medical products have become commonplace. Such studies begin by selecting a particular database, a decision that published papers invariably report but do not discuss. Studies of the same issue in different databases, however, can and do generate different results, sometimes with strikingly different clinical implications. In this paper, we systematically study heterogeneity among databases, holding other study methods constant, by exploring relative risk estimates for 53 drug-outcome pairs and 2 widely used study designs (cohort studies and self-controlled case series) across 10 observational databases. When holding the study design constant, our analysis shows that estimated relative risks range from a statistically significant decreased risk to a statistically significant increased risk in 11 of 53 (21%) of drug-outcome pairs that use a cohort design and 19 of 53 (36%) of drug-outcome pairs that use a self-controlled case series design. This exceeds the proportion of pairs that were consistent across databases in both direction and statistical significance, which was 9 of 53 (17%) for cohort studies and 5 of 53 (9%) for self-controlled case series. Our findings show that clinical studies that use observational databases can be sensitive to the choice of database. More attention is needed to consider how the choice of data source may be affecting results. PMID:23648805

    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

    In recent years, the Logical Observation Identifiers, Names, and Codes (LOINC) Database has been expanded to include assessment items of relevance to nursing and in 2002 met the criteria for "recognition" by the American Nurses Association. Assessment measures in LOINC include those related to vital signs, obstetric measurements, clinical assessment scales, assessments from standardized nursing terminologies, and research instruments. In order for LOINC to be of greater use in implementing information systems that support nursing practice, additional content is needed. Moreover, those implementing systems for nursing practice must be aware of the manner in which LOINC codes for assessments can be appropriately linked with other aspects of the nursing process such as diagnoses and interventions. Such linkages are necessary to document nursing contributions to healthcare outcomes within the context of a multidisciplinary care environment and to facilitate building of nursing knowledge from clinical practice. The purposes of this paper are to provide an overview of the LOINC database, to describe examples of assessments of relevance to nursing contained in LOINC, and to illustrate linkages of LOINC assessments with other nursing concepts.

    Clustering electronic medical records allows the discovery of information on healthcare practices. Entries in such medical records are usually composed of a succession of diagnostics or therapeutic steps. The corresponding processes are complex and heterogeneous since they depend on medical knowledge integrating clinical guidelines, the physician's individual experience, and patient data and conditions. To analyze such data, we are first proposing to cluster medical visits, consultations, and hospital stays into homogeneous groups, and then to construct higher-level patient treatment pathways over these different groups. These pathways are then also clustered to distill typical pathways, enabling interpretation of clusters by experts. This approach is evaluated on a real-world administrative database of elderly people in Québec suffering from heart failures. Copyright © 2018 Elsevier B.V. All rights reserved.

    NIED (Nat’l Res. Inst. for Earth Sci. & Disast. Prev.) has a project to develop two volcanic database systems: (1) volcanic observation database; (2) volcanic simulation database. The volcanic observation database is the data archive center obtained by the geophysical observation networks at Mt. Fuji, Miyake, Izu-Oshima, Iwo-jima and Nasu volcanoes, central Japan. The data consist of seismic (both high-sensitivity and broadband), ground deformation (tiltmeter, GPS) and those from other sensors (e.g., rain gauge, gravimeter, magnetometer, pressure gauge.) These data is originally stored in “WIN format,” the Japanese standard format, which is also at the Hi-net (High sensitivity seismic network Japan, http://www.hinet.bosai.go.jp/). NIED joins to WOVOdat and we have prepared to upload our data, via XML format. Our concept of the XML format is 1)a common format for intermediate files to upload into the WOVOdat DB, 2) for data files downloaded from the WOVOdat DB, 3) for data exchanges between observatories without the WOVOdat DB, 4) for common data files in each observatory, 5) for data communications between systems and softwares and 6)a for softwares. NIED is now preparing for (2) the volcanic simulation database. The objective of this project is to support to develop a “real-time” hazard map, i.e., the system which is effective to evaluate volcanic hazard in case of emergency, including the up-to-date conditions. Our system will include lava flow simulation (LavaSIM) and pyroclastic flow simulation (grvcrt). The database will keep many cases of assumed simulations and we can pick up the most probable case as the first evaluation in case the eruption started. The final goals of the both database will realize the volcanic eruption prediction and forecasting in real time by the combination of monitoring data and numerical simulations.

    Investigate the prevalence of obesity in Italy and examine its resource consumption and economic impact on the Italian national healthcare system (NHS). Retrospective, observational and real-life study. Data from three health units from Northern (Bergamo, Lombardy), Central (Grosseto, Tuscany) and Southern (Naples, Campania) Italy. All patients aged ≥18 years with at least one recorded body mass index (BMI) measurement between 1 January 2009 and 31 December 2012 were included. Information retrieved from the databases included primary care data, medical prescriptions, specialist consultations and hospital discharge records from 2009-2013. Costs associated with these data were also calculated. Data are presented for two time periods (1 year after BMI measurement and study end). Primary-to estimate health resources consumption and the associated economic impact on the Italian NHS. Secondary-the prevalence and characteristics of subjects by BMI category. 20 159 adult subjects with at least one documented BMI measurement. Subjects with BMI ≥30 kg/m 2 were defined as obese. The prevalence of obesity was 22.2% (N=4471) and increased with age. At the 1-year observation period, obese subjects who did not receive treatment for their obesity experienced longer durations of hospitalisation (median length: 5 days vs 3 days), used more prescription drugs (75.0% vs 57.7%), required more specialised outpatient healthcare (mean number: 5.3 vs 4.4) and were associated with greater costs, primarily owing to prescription drugs and hospital admissions (mean annual cost per year per patient: €460.6 vs €288.0 for drug prescriptions, €422.7 vs € 279.2 for hospitalisations and €283.2 vs €251.7 for outpatient care), compared with normal weight subjects. Similar findings were observed for the period up to data cut-off (mean follow-up of 2.7 years). Untreated obesity has a significant economic impact on the Italian healthcare system, highlighting the need to

    The physical healthcare environment is capable of affecting patients. This concept of 'healing environments' refers to the psychological impact of environmental stimuli through sensory perceptions. It excludes more physiological effects such as those produced by ergonomic (i.e. fall prevention) or facilitative (i.e. hygiene-related) variables. The importance of an atmosphere in the healthcare environment that promotes the health and well-being of patients is evident, but this environment should not negatively affect healthcare personnel. The physical healthcare environment is part of the personnel's 'workscape'. This can make the environment an important determinant of subjective work-related outcomes like job satisfaction and well-being, as well as of objective outcomes like absenteeism or quality of care. In order to effectively build or renovate healthcare facilities, it is necessary to pay attention to the needs of both patients and healthcare personnel. To assess the psychological effects of the physical healthcare environment on healthcare personnel. We searched the Cochrane EPOC Group Specialised Register; Cochrane Central Register of Controlled Trials; Database of Abstracts and Reviews of Effects; MEDLINE; EMBASE; CINAHL; Civil Engineering Database and Compendex. We also searched the reference lists of included studies. We included randomised controlled trials (RCT), controlled clinical trials (CCT), controlled before and after studies (CBA), and interrupted time series (ITS) of psychological effects of the physical healthcare environment interventions for healthcare staff. The outcomes included measures of job satisfaction, satisfaction with the physical healthcare environment, quality of life, and quality of care. Two reviewers independently assessed studies for eligibility, extracted data, and assessed methodological quality. We identified one study, which adopted a CBA study design to investigate the simultaneous effects of multiple environmental

    Background and objective : Automated healthcare databases (AHDB) are an important data source for real life drug and healthcare use. In the filed of depression, lack of detailed clinical data requires the use of binary proxies with important limitations. The study objective was to create a Depressive Health State Index (DHSI) as a continuous health state measure for depressed patients using available data in an AHDB. Methods: The study was based on historical cohort design using the UK Clinical Practice Research Datalink (CPRD). Depressive episodes (depression diagnosis with an antidepressant prescription) were used to create the DHSI through 6 successive steps: (1) Defining study design; (2) Identifying constituent parameters; (3) Assigning relative weights to the parameters; (4) Ranking based on the presence of parameters; (5) Standardizing the rank of the DHSI; (6) Developing a regression model to derive the DHSI in any other sample. Results : The DHSI ranged from 0 (worst) to 100 (best health state) comprising 29 parameters. The proportion of depressive episodes with a remission proxy increased with DHSI quartiles. Conclusion : A continuous outcome for depressed patients treated by antidepressants was created in an AHDB using several different variables and allowed more granularity than currently used proxies.

    As information technology creates opportunities for cooperation which crosses the boundaries between healthcare institutions, it will become an integral part of the Dutch healthcare system. Along with many involved organizations in healthcare the National IT Institute for Healthcare in the Netherlands (NICTIZ) is working on the realization of a national IT infrastructure for healthcare and a national electronic patient record (EPR). An underlying national architecture is designed to enable the Dutch EPR virtually, not in a national database, nor on a patient's smartcard. The required secure infrastructure provides generic functions for healthcare applications: patient identification, authentication and authorization of healthcare professionals. The first national applications in the EPR program using a national index of where patient data is stored, are the electronic medication record and the electronic record for after hours GP services. The rollout of the electronic medication record and electronic record for after hours GP services has been started in 2007. To guarantee progress of electronic data exchange in healthcare in the Netherlands we have primarily opted for two healthcare applications: the electronic medication record and the electronic record for after hours GP services. The use of a national switch-point containing the registry of where to find what information, guarantees that the professional receives the most recent information and omits large databases to contain downloaded data. Proper authorization, authentication as well as tracing by the national switchpoint also ensures a secure environment for the communication of delicate information.

    Research on healthcare delivery in zones of conflict requires sustained and systematic attention. In the context of the South Asian region, there has been an absence of research on the vulnerabilities of health care workers and institutions in areas affected by armed conflict. The paper presents a case study of the varied nature of security challenges faced by local healthcare providers in the state of Manipur in the North-eastern region of India, located in the Indo-Myanmar frontier region which has been experiencing armed violence and civil strife since the late 1960s. . The aim of this study was to assess longitudinal and spatial trends in incidents involving health care workers in Manipur during the period 2008 to 2009. We conducted a retrospective database analysis of the Manipur Micro-level Insurgency Database 2008-2009, created by using local newspaper archives to measure the overall burden of violence experienced in the state over a two year period. Publicly available press releases of armed groups and local hospitals in the state were used to supplement the quantitative data. Simple linear regression was used to assess longitudinal trends. Data was visualized with GIS-software for spatial analysis. The mean proportion of incidents involving health care workers per month was 2.7% and ranged between 0 and 6.1% (table 2). There was a significant (P=0.037) month-to-month variation in the proportion of incidents involving health care workers, as well as a upward trend of about 0.11% per month. Spatial analysis revealed different patterns depending on whether absolute, population-adjusted, or incident-adjusted frequencies served as the basis of the analysis. The paper shows a small but steady rise in violence against health workers and health institutions impeding health services in Manipur's pervasive violence. More evidence-building backed by research along with institutional obligations and commitment is essential to protect the health-systems Keywords: India

    In databases of observations unnoticed mistakes and misprints could occur at any stage of observation, preparation and processing of databases. The current detection of errors is complicated by the fact that the works of observer, databases compiler and researcher were divided. Data acquisition from a spacecraft requires the greater amount of researchers than for ground-based observations. As a result, the probability of errors is increasing. Keeping track of the errors on each stage is very difficult, so we use of cross-comparison of data from different sources. We revealed some misprints in the typographic and digital results of sunspot group area measurements.

    Wearable devices that measure physiological signals to help develop self-health management habits have become increasingly popular in recent years. These records are conducive for follow-up health and medical care. In this study, based on the characteristics of the observed physiological signal records- 1) a large number of users, 2) a large amount of data, 3) low information variability, 4) data privacy authorization, and 5) data access by designated users-we wish to resolve physiological signal record-relevant issues utilizing the advantages of the Database as a Service (DaaS) model. Storing a large amount of data using file patterns can reduce database load, allowing users to access data efficiently; the privacy control settings allow users to store data securely. The results of the experiment show that the proposed system has better database access performance than a traditional relational database, with a small difference in database volume, thus proving that the proposed system can improve data storage performance.

    Observational databases are increasingly acknowledged for their value in clinical investigation. Australian general practice in particular presents an exciting opportunity to examine treatment in a natural setting. The paper explores issues such as privacy and confidentiality--foremost considerations when conducting this form of pharmacoepidemiological research. Australian legislation is currently addressing these exact issues in order to establish clear directives regarding ethical concerns. The development of a pharmacoepidemiological database arising from the integration of computerized Australian general practice records is described in addition, to the challenges associated with creating a database which considers patient privacy. The database known as 'Medic-GP', presently contains more than 950,000 clinical notes (including consultations, pathology, diagnostic imaging and adverse reactions) over a 5-year time period and relates to 55,000 patients. The paper then details a retrospective study which utilized the database to examine the interaction between antibiotic prescribing and patient outcomes from a community perspective, following a policy intervention. This study illustrates the application of computerized general practice records in research.

    As computerization in healthcare services increase, the amount of available digital data is growing at an unprecedented rate and as a result healthcare organizations are much more able to store data than to extract knowledge from it. Today the major challenge is to transform these data into useful information and knowledge. It is important for healthcare organizations to use stored data to improve quality while reducing cost. This paper first investigates the data mining applications on centralized medical databases, and how they are used for diagnostic and population health, then introduces distributed databases. The integration needs and issues of distributed medical databases are described. Finally the paper focuses on data mining studies on distributed medical databases.

    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

    In the operational context of a local weather service, data accessibility and quality related issues must be managed by taking into account a wide set of user needs. This work describes the structure and the operational choices made for the operational implementation of a database system storing data from highly automated observing stations, metadata and information on data quality. Lombardy's environmental protection agency, ARPA Lombardia, manages a highly automated mesoscale meteorological network. A Quality Assurance System (QAS) ensures that reliable observational information is collected and disseminated to the users. The weather unit in ARPA Lombardia, at the same time an important QAS component and an intensive data user, has developed a database specifically aimed to: 1) providing quick access to data for operational activities and 2) ensuring data quality for real-time applications, by means of an Automatic Data Quality Control (ADQC) procedure. Quantities stored in the archive include hourly aggregated observations of: precipitation amount, temperature, wind, relative humidity, pressure, global and net solar radiation. The ADQC performs several independent tests on raw data and compares their results in a decision-making procedure. An important ADQC component is the Spatial Consistency Test based on Optimal Interpolation. Interpolated and Cross-Validation analysis values are also stored in the database, providing further information to human operators and useful estimates in case of missing data. The technical solution adopted is based on a LAMP (Linux, Apache, MySQL and Php) system, constituting an open source environment suitable for both development and operational practice. The ADQC procedure itself is performed by R scripts directly interacting with the MySQL database. Users and network managers can access the database by using a set of web-based Php applications.

    Within the last ten years healthcare services research has developed into an independent interdisciplinary field of research. A selective search of the literature was conducted in the database Google Scholar and the database on healthcare services research in Germany (http://versorgungsforschung-deutschland.de) for healthcare services research projects on pain in Germany. Healthcare services research projects were conducted by pharmaceutical companies, patient self-help organizations, scientific societies, statutory health insurance companies and university departments on acute and chronic pain. Valid data on the epidemiology, grading and treatment of chronic pain are available. There was an overuse of opioids and invasive procedures in patients with chronic low back pain, fibromyalgia syndrome and somatoform pain disorders. Databases for patients with chronic pain are currently constructed by pain societies. The fragmentation of data from health insurance companies, old age pension insurances, clinical institutions and population surveys and inconsistencies in diagnosing or encoding chronic pain impede the carrying out of significant longitudinal studies. Based on the data available, the needs of care for patients with chronic pain and the necessary care services cannot be derived. Important topics of future healthcare services research on pain are longitudinal studies on the cost efficacy and risks of inpatient and outpatient pain therapy based on routine data of health insurance companies, old age pension insurances and pain registries, longitudinal studies on "patient careers" (i.e. sequences of healthcare) and the identification of potential starting points for control of healthcare.

    Loss to follow-up (LTFU) in HIV-positive cohorts is an important surrogate for interrupted clinical care, which can potentially influence the assessment of HIV disease status and outcomes. After preliminary evaluation of LTFU rates and patient characteristics, we evaluated the risk of mortality by LTFU status in a high-resource setting. Rates of LTFU were measured in the Australian HIV Observational Database for a range of patient characteristics. Multivariate repeated measures regression methods were used to identify determinants of LTFU. Mortality by LTFU status was ascertained using linkage to the National Death Index. Survival following combination antiretroviral therapy initiation was investigated using the Kaplan-Meier (KM) method and Cox proportional hazards models. Of 3,413 patients included in this analysis, 1,632 (47.8%) had at least one episode of LTFU after enrolment. Multivariate predictors of LTFU included viral load (VL)>10,000 copies/ml (rate ratio [RR] 1.63; 95% CI 1.45, 1.84; ref ≤400), time under follow-up (per year; RR 1.03; 95% CI 1.02, 1.04) and prior LTFU (per episode; RR 1.15; 95% CI 1.06, 1.24). KM curves for survival were similar by LTFU status (P=0.484). LTFU was not associated with mortality in Cox proportional hazards models (univariate hazard ratio [HR] 0.93; 95% CI 0.69, 1.26) and multivariate HR 1.04 (95% CI 0.77, 1.43). Increased risk of LTFU was identified amongst patients with potentially higher infectiousness. We did not find significant mortality risk associated with LTFU. This is consistent with timely re-engagement with treatment, possibly via high levels of unreported linkage to other health-care providers.

    Imaging of physically inaccessible parts of the body such as the colon at micron-level resolution is highly important in diagnostic medical imaging. Though flexible endoscopes based on the imaging fiber bundle are used for such diagnostic procedures, their inherent honeycomb-like structure creates fiber pixelation effects. This impedes the observer from perceiving the information from an image captured and hinders the direct use of image processing and machine intelligence techniques on the recorded signal. Significant efforts have been made by researchers in the recent past in the development and implementation of pixelation removal techniques. However, researchers have often used their own set of images without making source data available which subdued their usage and adaptability universally. A database of pixelated images is the current requirement to meet the growing diagnostic needs in the healthcare arena. An innovative fiber pixelated image database is presented, which consists of pixelated images that are synthetically generated and experimentally acquired. Sample space encompasses test patterns of different scales, sizes, and shapes. It is envisaged that this proposed database will alleviate the current limitations associated with relevant research and development and would be of great help for researchers working on comb structure removal algorithms.

    The surveillance of antibiotic use in hospitals and of data on resistance is an essential measure for antibiotic stewardship. There are 3 national systems in France to collect data on antibiotic use: DREES, ICATB, and ATB RAISIN. We compared these databases and drafted recommendations for the creation of an optimized database of information on antibiotic use, available to all concerned personnel: healthcare authorities, healthcare facilities, and healthcare professionals. We processed and analyzed the 3 databases (2008 data), and surveyed users. The qualitative analysis demonstrated major discrepancies in terms of objectives, healthcare facilities, participation rate, units of consumption, conditions for collection, consolidation, and control of data, and delay before availability of results. The quantitative analysis revealed that the consumption data for a given healthcare facility differed from one database to another, challenging the reliability of data collection. We specified user expectations: to compare consumption and resistance data, to carry out benchmarking, to obtain data on the prescribing habits in healthcare units, or to help understand results. The study results demonstrated the need for a reliable, single, and automated tool to manage data on antibiotic consumption compared with resistance data on several levels (national, regional, healthcare facility, healthcare units), providing rapid local feedback and educational benchmarking.

    Objectives To evaluate the utility of applying the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) across multiple observational databases within an organization and to apply standardized analytics tools for conducting observational research. Materials and methods Six deidentified patient-level datasets were transformed to the OMOP CDM. We evaluated the extent of information loss that occurred through the standardization process. We developed a standardized analytic tool to replicate the cohort construction process from a published epidemiology protocol and applied the analysis to all 6 databases to assess time-to-execution and comparability of results. Results Transformation to the CDM resulted in minimal information loss across all 6 databases. Patients and observations excluded were due to identified data quality issues in the source system, 96% to 99% of condition records and 90% to 99% of drug records were successfully mapped into the CDM using the standard vocabulary.

    To investigate the safety of trivalent seasonal influenza vaccine (TIVc) (Optaflu ® ), the first cell culture seasonal trivalent influenza vaccine available in Europe. Codes and unstructured text in adult electronic healthcare records (The Health Improvement Network) were searched for a TIVc brand name or batch number and possible outcomes within a 3 month pre- to 6 month post-TIVc exposure study period (2012-2015). The outcomes were severe allergic reactions, Bell's palsy, convulsions, demyelination, paresthesia, noninfectious encephalitis, neuritis (optic and brachial), vasculitis, inflammatory bowel disease, and thrombocytopenia. Risk periods were defined based on biologically plausible time frame postvaccination when an outcome caused by the vaccine might be expected to occur. Possible outcomes were adjudicated against outcome specific case definitions and a date of onset assigned by using electronic and other medical records. Observed (risk period) to expected (outside risk and preexposure periods) rate ratios, postexposure incidence, and plots of time from exposure to outcome were reported. Sixteen of 1011 events from 4578 exposures fulfilled a primary case definition and had a date of onset during the study period. Three were in observed time. The observed-to-expected rate ratios were (3.3, 95% CI 0.3, 31.7) for convulsions and (1.5, 95% CI 0.2, 14.9) for thrombocytopenia with 1 outcome each in observed time. There was 1 incident inflammatory bowel disease in observed, but none in expected, time. The small sample size restricts interpretation; however, no hypothesis of an increased risk of a study outcome was generated. Adjudication of events against case definitions to reduce misclassification of onset and outcomes allowed use of precise risk periods. KEY POINTS This observational study did not generate a hypothesis of an association between the first cell-culture seasonal influenza vaccination available in the European Union and any of the study

    To evaluate the accuracy of disease codes and free text in identifying upper gastrointestinal bleeding (UGIB) from electronic health-care records (EHRs). We conducted a validation study in four European electronic health-care record (EHR) databases such as Integrated Primary Care Information (IPCI), Health Search/CSD Patient Database (HSD), ARS, and Aarhus, in which we identified UGIB cases using free text or disease codes: (1) International Classification of Disease (ICD)-9 (HSD, ARS); (2) ICD-10 (Aarhus); and (3) International Classification of Primary Care (ICPC) (IPCI). From each database, we randomly selected and manually reviewed 200 cases to calculate positive predictive values (PPVs). We employed different case definitions to assess the effect of outcome misclassification on estimation of risk of drug-related UGIB. PPV was 22% [95% confidence interval (CI): 16, 28] and 21% (95% CI: 16, 28) in IPCI for free text and ICPC codes, respectively. PPV was 91% (95% CI: 86, 95) for ICD-9 codes and 47% (95% CI: 35, 59) for free text in HSD. PPV for ICD-9 codes in ARS was 72% (95% CI: 65, 78) and 77% (95% CI: 69, 83) for ICD-10 codes (Aarhus). More specific definitions did not have significant impact on risk estimation of drug-related UGIB, except for wider CIs. ICD-9-CM and ICD-10 disease codes have good PPV in identifying UGIB from EHR; less granular terminology (ICPC) may require additional strategies. Use of more specific UGIB definitions affects precision, but not magnitude, of risk estimates. Copyright © 2014 Elsevier Inc. All rights reserved.

    To evaluate the utility of applying the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) across multiple observational databases within an organization and to apply standardized analytics tools for conducting observational research. Six deidentified patient-level datasets were transformed to the OMOP CDM. We evaluated the extent of information loss that occurred through the standardization process. We developed a standardized analytic tool to replicate the cohort construction process from a published epidemiology protocol and applied the analysis to all 6 databases to assess time-to-execution and comparability of results. Transformation to the CDM resulted in minimal information loss across all 6 databases. Patients and observations excluded were due to identified data quality issues in the source system, 96% to 99% of condition records and 90% to 99% of drug records were successfully mapped into the CDM using the standard vocabulary. The full cohort replication and descriptive baseline summary was executed for 2 cohorts in 6 databases in less than 1 hour. The standardization process improved data quality, increased efficiency, and facilitated cross-database comparisons to support a more systematic approach to observational research. Comparisons across data sources showed consistency in the impact of inclusion criteria, using the protocol and identified differences in patient characteristics and coding practices across databases.

    Since the last 30 years, phenology has regained scientific interest as the most reported biological indicator of anthropogenic climate change. AEMET (Spanish National Meteorological Agency) has long records in the field of phenological observations, since the 1940s. However, there is a large variety of paper records which are necessary to digitalize. On the other hand, it had been necessary to adapt our methods to the World Meteorological Organization (WMO) guidelines (BBCH code, data documentation- metadata…) and to standardize phenological stages and species in order to provide information to PEP725 (Pan European Phenology Database). Consequently, AEMET is developing a long-term, multi-taxa phenological database to support research and scientific studies about climate, their variability and influence on natural ecosystems, agriculture, etc. This paper presents the steps that are being carried out in order to achieve this goal.

    Real-world research can use observational or clinical trial designs, in both cases putting emphasis on high external validity, to complement the classical efficacy randomized controlled trials (RCTs) with high internal validity. Real-world research is made necessary by the variety of factors that can play an important a role in modulating effectiveness in real life but are often tightly controlled in RCTs, such as comorbidities and concomitant treatments, adherence, inhalation technique, access to care, strength of doctor-caregiver communication, and socio-economic and other organizational factors. Real-world studies belong to two main categories: pragmatic trials and observational studies, which can be prospective or retrospective. Focusing on comparative database observational studies, the process aimed at ensuring high-quality research can be divided into three parts: preparation of research, analyses and reporting, and discussion of results. Key points include a priori planning of data collection and analyses, identification of appropriate database(s), proper outcomes definition, study registration with commitment to publish, bias minimization through matching and adjustment processes accounting for potential confounders, and sensitivity analyses testing the robustness of results. When these conditions are met, observational database studies can reach a sufficient level of evidence to help create guidelines (i.e., clinical and regulatory decision-making).

    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.

  13. Obtaining evidence for use by healthcare payers on the success of chronic obstructive pulmonary disease management.

    Healthcare payers make decisions on funding for treatments for diseases, such as chronic obstructive pulmonary disease (COPD), on a population level, so require evidence of treatment success in appropriate populations, using usual routine care as the comparison for alternative management approaches. Such health outcomes evidence can be obtained from a number of sources. The 'gold standard' method for obtaining evidence of treatment success is usually taken as the randomized controlled prospective clinical trial. Yet the value of such studies in providing evidence for decision-makers can be questioned due to the restricted entry criteria limiting the ability to generalize to real life populations, narrow focus on individual parameters, use of placebo for comparison rather than usual therapy and unrealistic intense monitoring of patients. Evidence obtained from retrospective and observational studies can supplement that from randomized clinical trials, providing that care is taken to guard against bias and confounders. However, very large numbers of patients must be investigated if small differences between drugs and treatment approaches are to be detected. Administrative databases from healthcare systems provide an opportunity to obtain observational data on large numbers of patients. Such databases have shown that high healthcare costs in patients with COPD are associated with co-morbid conditions and current smoking status. Analysis of an administrative database has also shown that elderly patients with COPD who received inhaled corticosteroids within 90 days of discharge from hospital had 24% fewer repeat hospitalizations for COPD and were 29% less likely to die during the 1-year follow-up period. In conclusion, there are a number of sources of meaningful evidence of the health outcomes arising from different therapeutic approaches that should be of value to healthcare payers making decisions on resource allocation.

    Administrative healthcare databases are useful tools to study healthcare outcomes and to monitor the health status of a population. Patients with cancer can be identified through disease-specific codes, prescriptions and physician claims, but prior validation is required to achieve an accurate case definition. The objective of this protocol is to assess the accuracy of International Classification of Diseases Ninth Revision-Clinical Modification (ICD-9-CM) codes for breast, lung and colorectal cancers in identifying patients diagnosed with the relative disease in three Italian administrative databases. Data from the administrative databases of Umbria Region (910,000 residents), Local Health Unit 3 of Napoli (1,170,000 residents) and Friuli--Venezia Giulia Region (1,227,000 residents) will be considered. In each administrative database, patients with the first occurrence of diagnosis of breast, lung or colorectal cancer between 2012 and 2014 will be identified using the following groups of ICD-9-CM codes in primary position: (1) 233.0 and (2) 174.x for breast cancer; (3) 162.x for lung cancer; (4) 153.x for colon cancer and (5) 154.0-154.1 and 154.8 for rectal cancer. Only incident cases will be considered, that is, excluding cases that have the same diagnosis in the 5 years (2007-2011) before the period of interest. A random sample of cases and non-cases will be selected from each administrative database and the corresponding medical charts will be assessed for validation by pairs of trained, independent reviewers. Case ascertainment within the medical charts will be based on (1) the presence of a primary nodular lesion in the breast, lung or colon-rectum, documented with imaging or endoscopy and (2) a cytological or histological documentation of cancer from a primary or metastatic site. Sensitivity and specificity with 95% CIs will be calculated. Study results will be disseminated widely through peer-reviewed publications and presentations at national and

    Advances in allogeneic hematopoietic cell transplantation for sickle cell disease have improved outcomes, but there is limited analysis of healthcare utilization in this setting. We hypothesized that, compared to late transplantation, early transplantation (at age <10 years) improves outcomes and decreases healthcare utilization. We performed a retrospective study of children transplanted for sickle cell disease in the USA during 2000–2013 using two large databases. Univariate and Cox models were used to estimate associations of demographics, sickle cell disease severity, and transplant-related variables with mortality and chronic graft-versus-host disease, while Wilcoxon, Kruskal-Wallis, or linear trend tests were applied for the estimates of healthcare utilization. Among 161 patients with a 2-year overall survival rate of 90% (95% confidence interval [CI] 85–95%) mortality was significantly higher in those who underwent late transplantation versus early (hazard ratio (HR) 21, 95% CI 2.8–160.8, P=0.003) and unrelated compared to matched sibling donor transplantation (HR 5.9, 95% CI 1.7–20.2, P=0.005). Chronic graftversus host disease was significantly more frequent among those translanted late (HR 1.9, 95% CI 1.0–3.5, P=0.034) and those who received an unrelated graft (HR 2.5, 95% CI 1.2–5.4; P=0.017). Merged data for 176 patients showed that the median total adjusted transplant cost per patient was $467,747 (range: $344,029–$799,219). Healthcare utilization was lower among recipients of matched sibling donor grafts and those with low severity disease compared to those with other types of donor and disease severity types (P<0.001 and P=0.022, respectively); no association was demonstrated with late transplantation (P=0.775). Among patients with 2-year pre- and post-transplant data (n=41), early transplantation was associated with significant reductions in admissions (P<0.001), length of stay (P<0.001), and cost (P=0.008).

    Value-based healthcare (VBHC) is considered to be the solution that will improve quality and decrease costs in healthcare. Many hospitals are implementing programs on the basis of this strategy, but rigorous scientific reports are still lacking. In this pilot study, we present the first-year outcomes of a VBHC program for inflammatory bowel disease (IBD) management that focuses on highly coordinated care, task differentiation of providers, and continuous home monitoring. IBD patients treated within the VBHC program were identified in an administrative claims database from a commercial insurer allowing comparisons to matched controls. Only patients for whom data were available the year before and after starting the program were included. Healthcare utilization including visits, hospitalizations, laboratory and imaging tests, and medications were compared between groups. In total, 60 IBD patients treated at the VBHC Center were identified and were matched to 177 controls. Significantly fewer upper endoscopies were performed (-10%, P=0.012), and numerically fewer surgeries (-25%, P=0.49), hospitalizations (-28%, 0=0.71), emergency department visits (-37%, P=0.44), and imaging studies (-25 to -86%) were observed. In addition, 65% fewer patients (P=0.16) used steroids long term. IBD-related costs were 16% ($771) lower than expected (P=0.24). These are the first results of a successfully implemented VBHC program for IBD. Encouraging trends toward fewer emergency department visits, hospitalizations, and long-term corticosteroid use were observed. These results will need to be confirmed in a larger sample with more follow-up.

    Studies on drug utilization usually do not allow direct cross-national comparisons because of differences in the respective applied methods. This study aimed to compare time trends in BZDs prescribing by applying a common protocol and analyses plan in seven European electronic healthcare databases. Crude and standardized prevalence rates of drug prescribing from 2001-2009 were calculated in databases from Spain, United Kingdon (UK), The Netherlands, Germany and Denmark. Prevalence was stratified by age, sex, BZD type [(using ATC codes), i.e. BZD-anxiolytics BZD-hypnotics, BZD-related drugs and clomethiazole], indication and number of prescription. Crude prevalence rates of BZDs prescribing ranged from 570 to 1700 per 10,000 person-years over the study period. Standardization by age and sex did not substantially change the differences. Standardized prevalence rates increased in the Spanish (+13%) and UK databases (+2% and +8%) over the study period, while they decreased in the Dutch databases (-4% and -22%), the German (-12%) and Danish (-26%) database. Prevalence of anxiolytics outweighed that of hypnotics in the Spanish, Dutch and Bavarian databases, but the reverse was shown in the UK and Danish databases. Prevalence rates consistently increased with age and were two-fold higher in women than in men in all databases. A median of 18% of users received 10 or more prescriptions in 2008. Although similar methods were applied, the prevalence of BZD prescribing varied considerably across different populations. Clinical factors related to BZDs and characteristics of the databases may explain these differences. Copyright © 2015 John Wiley & Sons, Ltd.

    Currently, ophthalmic surgical cases are not included in the Veterans Administration Surgical Quality Improvement Project data collection. Furthermore, there is no comprehensive protocol in the health system for prospectively measuring outcomes for eye surgery in terms of safety and quality. There are 400,000 operative cases in the system per year. Of those, 48,000 (12%) are ophthalmic surgical cases, with 85% (41,000) of those being cataract cases. The Ophthalmic Surgical Outcome Database Pilot Project was developed to incorporate ophthalmology into VASQIP, thus evaluating risk factors and improving cataract surgical outcomes. Nurse reviewers facilitate the monitoring and measuring of these outcomes. Since its inception in 1778, the Veterans Administration (VA) Health System has provided comprehensive healthcare to millions of deserving veterans throughout the U.S. and its territories. Historically, the quality of healthcare provided by the VA has been the main focus of discussion because it did not meet a standard of care comparable to that of the private sector. Information regarding quality of healthcare services and outcomes data had been unavailable until 1986, when Congress mandated the VA to compare its surgical outcomes to those of the private sector (PL-99-166). 1 Risk adjustment of VA surgical outcomes began in 1987 with the Continuous Improvement in Cardiac Surgery Program (CICSP) in which cardiac surgical outcomes were reported and evaluated. 2 Between 1991 and 1993, the National VA Surgical Risk Study (NVASRS) initiated a validated risk-adjustment model for predicting surgical outcomes and comparative assessment of the quality of surgical care in 44 VA medical centers. 3 The success of NVASRS encouraged the VA to establish an ongoing program for monitoring and improving the quality of surgical care, thus developing the National Surgical Quality Improvement Program (NSQIP) in 1994. 4 According to a prospective study conducted between 1991-1997 in 123

    Today's healthcare executives and leaders must have management talent sophisticated enough to match the increased complexity of the healthcare environment. Executives are expected to demonstrate measurable outcomes and effectiveness and to practice evidence-based management. At the same time, academic and professional programs are emphasizing the attainment of competencies related to workplace effectiveness. The shift to evidence-based management has led to numerous efforts to define the competencies most appropriate for healthcare. The Healthcare Leadership Alliance (HLA), a consortium of six major professional membership organizations, used the research from and experience with their individual credentialing processes to posit five competency domains common among all practicing healthcare managers: (1) communication and relationship management, (2) professionalism, (3) leadership, (4) knowledge of the healthcare system, and (5) business skills and knowledge. The HLA engaged in a formal process to delineate the knowledge, skills, and abilities within each domain and to determine which of these competencies were core or common among the membership of all HLA associations and which were specialty or specific to the members of one or more HLA organizations. This process produced 300 competency statements, which were then organized into the Competency Directory, a unique and interactive database that can be used for assessing individual and organizational competencies. Overall, this work helps to unify the field of healthcare management and provides a lexicon and a basis for collaboration among different types of healthcare executives. This article discusses the steps that the HLA followed. It also presents the HLA Competency Directory; its application and relevance to the practitioner and academic communities; and its strengths, limitations, and potential.

    Healthcare service use among suicide decedents must be well characterized and understood since a key strategy for preventing suicide is to improve healthcare providers' ability to effectively detect and treat those in need. To determine gender differences in healthcare service use 12 months prior to suicide. Data for 1,231 young Quebec residents (≤ 25 years) who died by suicide between 2000 and 2007 were collected from public health insurance agency databases and coroner registers. Healthcare visits were categorized according to the setting (emergency department [ED], outpatient, and hospital) and their nature (mental health vs. non-mental health). Girls were more likely than boys (82.5% vs. 74.9%, p = .011) to have used healthcare services in the year prior to death. A higher proportion of girls had used outpatient services (79.0% vs. 69.5%, p = .003), had been hospitalized (25.7% vs. 15.6%, p < .001) and had received a mental health-related diagnosis (46.7% vs. 33.1%, p < .001). However, no gender differences were observed in ED visits (59.5% vs. 54.5%, p = .150). There is an important proportion of suicide decedents who did not receive a mental health diagnosis and healthcare services in the year prior to death. Future studies should focus on examining gender-specific individual and health system barriers among suicide decedents as well as the quality of care offered regarding detection and treatment.

    To quantify the risk of pneumococcal pneumonia (PP) and invasive pneumococcal disease (IPD) in adults aged ≥19 years with underlying medical conditions compared with healthy adults of the same age in Japan. An observational, retrospective, cohort study using two healthcare claims databases in Japan: Japan Medical Data Center (JMDC) and Medical Data Vision (MDV) databases. A total of 10.4 million individuals, representing 9.3 million person-years of follow-up, were included in the analysis. Eleven medical conditions as well as PP and IPD were identified by the International Statistical Classification of Diseases and Related Health Problems version 10 diagnostic codes and/or local disease codes used in Japan. Adjusted rate ratios (RRs) for PP and IPD in adults with a medical condition versus adults without any medical condition were calculated using multivariate Poisson regression models with age and/or sex as covariates. In the JMDC and MDV databases, respectively, adults ≥19 years with a medical condition (RRs for PP: 3.3 to 13.4, 1.7 to 5.2; RRs for IPD: 12.6 to 43.3, 4.4 to 7.1), adults with two or more medical conditions (PP: 11.6, 2.8; IPD: 18.7, 5.8) and high-risk adults (PP: 12.9, 1.8; IPD: 29.7, 4.0) were at greater risk of PP and IPD compared with their healthy counterparts. Adults aged 50-64 years with an underlying medical condition (PP rate: 38.6 to 212.1 per 100 000 person-years) had a higher rate of PP than those aged ≥65 years without any condition (PP rate: 13.2 to 93.0 per 100 000 person-years). Adults of all ages with an underlying medical condition are at greater risk of PP and IPD compared with adults without any medical condition. This risk increases with the number of underlying medical conditions. Our results support extending pneumococcal vaccination to younger adults with an underlying medical condition, especially those aged 50-64 years. © Article author(s) (or their employer(s) unless otherwise stated in the text of the

    In support of the first Tropospheric Ozone Assessment Report (TOAR) a relational database of global surface ozone observations has been developed and populated with hourly measurement data and enhanced metadata. A comprehensive suite of ozone data products including standard statistics, health and vegetation impact metrics, and trend information, are made available through a common data portal and a web interface. These data form the basis of the TOAR analyses focusing on human health, vegetation, and climate relevant ozone issues. Cooperation among many data centers and individual researchers worldwide made it possible to build the world's largest collection of in-situ hourly surface ozone data covering the period from 1970 to 2015. By combining the data from almost 10,000 measurement sites around the world with global metadata information, new analyses of surface ozone have become possible, such as the first globally consistent characterisations of measurement sites as either urban or rural/remote. Exploitation of these global metadata allows for new insights into the global distribution, and seasonal and long-term changes of tropospheric ozone and they enable TOAR to perform the first, globally consistent analysis of present-day ozone concentrations and recent ozone changes with relevance to health, agriculture, and climate. This presentation will provide a summary of the TOAR surface observations database including recent additions of ozone precursor and meteorological data. We will demonstrate how the database can be accessed and the data can be used, and we will discuss its limitations and the potential for closing some of teh remaining data gaps.

    Nowadays, e-healthcare is a main advancement and upcoming technology in healthcare industry that contributes to setting up automated and efficient healthcare infrastructures. Unfortunately, several security aspects remain as main challenges towards secure and privacy-preserving e-healthcare systems. From the access control perspective, e-healthcare systems face several issues due to the necessity of defining (at the same time) rigorous and flexible access control solutions. This delicate and irregular balance between flexibility and robustness has an immediate impact on the compliance of the deployed access control policy. To address this issue, the paper defines a general framework to organize thinking about verifying, validating and monitoring the compliance of access control policies in the context of e-healthcare databases. We study the problem of the conformity of low level policies within relational databases and we particularly focus on the case of a medical-records management database defined in the context of a Medical Information System. We propose an advanced solution for deploying reliable and efficient access control policies. Our solution extends the traditional lifecycle of an access control policy and allows mainly managing the compliance of the policy. We refer to an example to illustrate the relevance of our proposal.

  4. Healthcare avoidance: a critical review.

    The purpose of this study is to provide a critical review and synthesis of theoretical and research literature documenting the impact of avoidance on healthcare behaviors, identify the factors that influence healthcare avoidance and delay in the adult population, and propose a direction for future research. The Theory of Reasoned Action, Theory of Planned Behavior, Theory of Care-Seeking Behavior, the Transtheoretical Model, and the Behavioral Model of Health Services Use/Utilization are utilized to elaborate on the context within which individual intention to engage in healthcare behaviors occurs. Research literature on the concept of healthcare avoidance obtained by using computerized searches of CINAHL, MEDLINE, PSYCH INFO, and HAPI databases, from 1995 to 2007, were reviewed. Studies were organized by professional disciplines. Healthcare avoidance is a common and highly variable experience. Multiple administrative, demographic, personal, and provider factors are related to healthcare avoidance, for example, distrust of providers and/or the science community, health beliefs, insurance status, or socioeconomic/income level. Although the concept is recognized by multiple disciplines, limited research studies address its impact on healthcare decision making. More systematic research is needed to determine correlates of healthcare avoidance. Such studies will help investigators identify patients at risk for avoidant behaviors and provide the basis for health-promoting interventions. Methodological challenges include identification of characteristics of individuals and environments that hinder healthcare behaviors, as well as, the complexity of measuring healthcare avoidance. Studies need to systematically explore the influence of avoidance behaviors on specific healthcare populations at risk.

    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

    The term big data refers to databases that include large amounts of information used in various areas of knowledge. Currently, there are large databases that allow the evaluation of postoperative evolution, such as the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP), the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS), and the National Cancer Database (NCDB). The aim of this review was to evaluate the clinical impact of information obtained from these registries regarding gastroesophageal surgery. A systematic review using the Meta-analysis of Observational Studies in Epidemiology guidelines was performed. The research was carried out using the PubMed database identifying 251 articles. All outcomes related to gastroesophageal surgery were analyzed. A total of 34 articles published between January 2007 and July 2017 were included, for a total of 345 697 patients. Studies were analyzed and divided according to the type of surgery and main theme in (1) esophageal surgery and (2) gastric surgery. The information provided by these databases is an effective way to obtain levels of evidence not obtainable by conventional methods. Furthermore, this information is useful for the external validation of previous studies, to establish benchmarks that allow comparisons between centers and have a positive impact on the quality of care.

    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.

    We present the first volume of the Einstein quasar database. The database includes estimates of the X-ray count rates, fluxes, and luminosities for 514 quasars and Seyfert 1 galaxies observed with the Imaging Proportional Counter (IPC) aboard the Einstein Observatory. All were previously known optically selected or radio-selected objects, and most were the targets of the X-ray observations. The X-ray properties of the Active Galactic Nuclei (AGNs) have been derived by reanalyzing the IPC data in a systematic manner to provide a uniform database for general use by the astronomical community. We use the database to extend earlier quasar luminosity studies which were made using only a subset of the currently available data. The database can be accessed on internet via the SAO Einstein on-line system ('Einline') and is available in ASCII format on magnetic tape and DOS diskette.

    Healthcare applications that have access control, disclosure management and or privacy enforcement requirements may implement the respective solutions to these issues at the application level or at the database level or in both. Unfortunately, there are technical and non-technical factors that influence what can be done. In this paper we present a flexible, simple and novel approach to seamlessly imbuing current healthcare applications and their supporting infrastructure with security and privacy functionality, while being cognizant of these factors. This approach is called the Chain method. This paper will highlight the smaller design footprint, the increased ease of implementation and use of the Chain method, while demonstrating that it is as powerful and effective as traditional methods.

    The adoption of healthcare technology is arduous, and it requires planning and implementation time. Healthcare organizations are vulnerable to modern trends and threats because it has not kept up with threats. The objective of this systematic review is to identify cybersecurity trends, including ransomware, and identify possible solutions by querying academic literature. The reviewers conducted three separate searches through the CINAHL and PubMed (MEDLINE) and the Nursing and Allied Health Source via ProQuest databases. Using key words with Boolean operators, database filters, and hand screening, we identified 31 articles that met the objective of the review. The analysis of 31 articles showed the healthcare industry lags behind in security. Like other industries, healthcare should clearly define cybersecurity duties, establish clear procedures for upgrading software and handling a data breach, use VLANs and deauthentication and cloud-based computing, and to train their users not to open suspicious code. The healthcare industry is a prime target for medical information theft as it lags behind other leading industries in securing vital data. It is imperative that time and funding is invested in maintaining and ensuring the protection of healthcare technology and the confidentially of patient information from unauthorized access.

    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

    There is growing interest in using routinely collected data from health care databases to study the safety and effectiveness of therapies in "real-world" conditions, as it can provide complementary evidence to that of randomized controlled trials. Causal inference from health care databases is challenging because the data are typically noisy, high dimensional, and most importantly, observational. It requires methods that can estimate heterogeneous treatment effects while controlling for confounding in high dimensions. Bayesian additive regression trees, causal forests, causal boosting, and causal multivariate adaptive regression splines are off-the-shelf methods that have shown good performance for estimation of heterogeneous treatment effects in observational studies of continuous outcomes. However, it is not clear how these methods would perform in health care database studies where outcomes are often binary and rare and data structures are complex. In this study, we evaluate these methods in simulation studies that recapitulate key characteristics of comparative effectiveness studies. We focus on the conditional average effect of a binary treatment on a binary outcome using the conditional risk difference as an estimand. To emulate health care database studies, we propose a simulation design where real covariate and treatment assignment data are used and only outcomes are simulated based on nonparametric models of the real outcomes. We apply this design to 4 published observational studies that used records from 2 major health care databases in the United States. Our results suggest that Bayesian additive regression trees and causal boosting consistently provide low bias in conditional risk difference estimates in the context of health care database studies.

  13. Heterogeneous database integration in biomedicine.

    PubMed

    Sujansky, W

    2001-08-01

    The rapid expansion of biomedical knowledge, reduction in computing costs, and spread of internet access have created an ocean of electronic data. The decentralized nature of our scientific community and healthcare system, however, has resulted in a patchwork of diverse, or heterogeneous, database implementations, making access to and aggregation of data across databases very difficult. The database heterogeneity problem applies equally to clinical data describing individual patients and biological data characterizing our genome. Specifically, databases are highly heterogeneous with respect to the data models they employ, the data schemas they specify, the query languages they support, and the terminologies they recognize. Heterogeneous database systems attempt to unify disparate databases by providing uniform conceptual schemas that resolve representational heterogeneities, and by providing querying capabilities that aggregate and integrate distributed data. Research in this area has applied a variety of database and knowledge-based techniques, including semantic data modeling, ontology definition, query translation, query optimization, and terminology mapping. Existing systems have addressed heterogeneous database integration in the realms of molecular biology, hospital information systems, and application portability.

    To improve the quality of patient treatment by improving the functionality of medical devices in healthcare institutions. To present the results of the safety and performance inspection of patient-relevant output parameters of anesthesia machines and defibrillators defined by legal metrology. This study covered 130 anesthesia machines and 161 defibrillators used in public and private healthcare institutions, during a period of two years. Testing procedures were carried out according to international standards and legal metrology legislative procedures in Bosnia and Herzegovina. The results show that in 13.84% of tested anesthesia machine and 14.91% of defibrillators device performance is not in accordance with requirements and should either have its results be verified, or the device removed from use or scheduled for corrective maintenance. Research emphasizes importance of independent safety and performance inspections, and gives recommendations for the frequency of inspection based on measurements. Results offer implications for adequacy of preventive and corrective maintenance performed in healthcare institutions. Based on collected data, the first digital electronical database of anesthesia machines and defibrillators used in healthcare institutions in Bosnia and Herzegovina is created. This database is a useful tool for tracking each device's performance over time.

    The IUGONET is a Japanese program to build a metadata database for ground-based observations of the upper atmosphere [1]. The project began in 2009 with five Japanese institutions which archive data observed by radars, magnetometers, photometers, radio telescopes and helioscopes, and so on, at various altitudes from the Earth's surface to the Sun. Systems have been developed to allow searching of the above described metadata. We have been updating the system and adding new and updated metadata. The IUGONET development team adopted the SPASE metadata model [2] to describe the upper atmosphere data. This model is used as the common metadata format by the virtual observatories for solar-terrestrial physics. It includes metadata referring to each data file (called a 'Granule'), which enable a search for data files as well as data sets. Further details are described in [2] and [3]. Currently, three additional Japanese institutions are being incorporated in IUGONET. Furthermore, metadata of observations of the troposphere, taken at the observatories of the middle and upper atmosphere radar at Shigaraki and the Meteor radar in Indonesia, have been incorporated. These additions will contribute to efficient interdisciplinary scientific research. In the beginning of 2013, the registration of the 'Observatory' and 'Instrument' metadata was completed, which makes it easy to overview of the metadata database. The number of registered metadata as of the end of July, totalled 8.8 million, including 793 observatories and 878 instruments. It is important to promote interoperability and/or metadata exchange between the database development groups. A memorandum of agreement has been signed with the European Near-Earth Space Data Infrastructure for e-Science (ESPAS) project, which has similar objectives to IUGONET with regard to a framework for formal collaboration. Furthermore, observations by satellites and the International Space Station are being incorporated with a view for

    Future climate change will dramatically change the carbon balance in the soil, and this change will affect the terrestrial carbon stock and the climate itself. Earth system models (ESMs) are used to understand the current climate and to project future climate conditions, but the soil organic carbon (SOC) stock simulated by ESMs and those of observational databases are not well correlated when the two are compared at fine grid scales. However, the specific key processes and factors, as well as the relationships among these factors that govern the SOC stock, remain unclear; the inclusion of such missing information would improve the agreement between modeled and observational data. In this study, we sought to identify the influential factors that govern global SOC distribution in observational databases, as well as those simulated by ESMs. We used a data-mining (machine-learning) (boosted regression trees - BRT) scheme to identify the factors affecting the SOC stock. We applied BRT scheme to three observational databases and 15 ESM outputs from the fifth phase of the Coupled Model Intercomparison Project (CMIP5) and examined the effects of 13 variables/factors categorized into five groups (climate, soil property, topography, vegetation, and land-use history). Globally, the contributions of mean annual temperature, clay content, carbon-to-nitrogen (CN) ratio, wetland ratio, and land cover were high in observational databases, whereas the contributions of the mean annual temperature, land cover, and net primary productivity (NPP) were predominant in the SOC distribution in ESMs. A comparison of the influential factors at a global scale revealed that the most distinct differences between the SOCs from the observational databases and ESMs were the low clay content and CN ratio contributions, and the high NPP contribution in the ESMs. The results of this study will aid in identifying the causes of the current mismatches between observational SOC databases and ESM outputs

    Simulation is widely used in health professional education. The convention that learners are actively involved may limit access to this educational method. The aim of this paper is to review the evidence for learning methods that employ directed observation as an alternative to hands-on participation in scenario-based simulation training. We sought studies that included either direct comparison of the learning outcomes of observers with those of active participants or identified factors important for the engagement of observers in simulation. We systematically searched health and education databases and reviewed journals and bibliographies for studies investigating or referring to observer roles in simulation using mannequins, simulated patients or role play simulations. A quality framework was used to rate the studies. We sought studies that included either direct comparison of the learning outcomes of observers with those of active participants or identified factors important for the engagement of observers in simulation. We systematically searched health and education databases and reviewed journals and bibliographies for studies investigating or referring to observer roles in simulation using mannequins, simulated patients or role play simulations. A quality framework was used to rate the studies. Nine studies met the inclusion criteria. Five studies suggest learning outcomes in observer roles are as good or better than hands-on roles in simulation. Four studies document learner satisfaction in observer roles. Five studies used a tool to guide observers. Eight studies involved observers in the debrief. Learning and satisfaction in observer roles is closely associated with observer tools, learner engagement, role clarity and contribution to the debrief. Learners that valued observer roles described them as affording an overarching view, examination of details from a distance, and meaningful feedback during the debrief.

    The Mexican Institute of Social Security (IMSS) provides a package of health, economic and social benefits to workers employed in private firms within the formal labour market and to their economic dependants. Affiliates have a right to these benefits only while they remain contracted, thus posing a risk for the continuity of healthcare. This study evaluates the association between the time (in days) without the right to healthcare due to job loss in the formal labour market and the quality of healthcare and clinical outcomes among IMSS affiliates with Type 2 diabetes mellitus (T2DM). Retrospective cohort study 2013-2015. Six IMSS family medicine clinics (FMC) in Mexico City. T2DM patients (n = 27 217) affiliated with job-related health insurance and at least one consultation with a family doctor during 2013. IMSS affiliation department database and electronic health records and clinical laboratory databases. Quality of the processes (eight indicators) and outcomes (three indicators) of healthcare. The results indicated that losing IMSS right to healthcare is frequent, occurring to one-third of T2DM patients during the follow-up period. The time without the right to healthcare in the observed period was of 120 days on average and was associated with a 43.2% loss of quality of care and a 19.2% reduction in clinical outcomes of T2DM. Policies aimed at ensuring access and continuity of care, regardless of job status, are critical for improving the quality of processes and outcomes of healthcare for diabetic patients.

    Healthcare workers are exposed to a variety of work-related hazards including biological, chemical, physical, ergonomic, psychological hazards; and workplace violence. The Occupational Health and Safety Agency for Healthcare in British Columbia (OHSAH), in conjunction with British Columbia (BC) health regions, developed and implemented a comprehensive surveillance system that tracks occupational exposures and stressors as well as injuries and illnesses among a defined population of healthcare workers. Workplace Health Indicator Tracking and Evaluation (WHITE) is a secure operational database, used for data entry and transaction reporting. It has five modules: Incident Investigation, Case Management, Employee Health, Health and Safety, and Early Intervention/Return to Work. Since the WHITE database was first introduced into BC in 2004, it has tracked the health of 84,318 healthcare workers (120,244 jobs), representing 35,927 recorded incidents, resulting in 18,322 workers' compensation claims. Currently, four of BC's six healthcare regions are tracking and analyzing incidents and the health of healthcare workers using WHITE, providing OHSAH and healthcare stakeholders with comparative performance indicators on workplace health and safety. A number of scientific manuscripts have also been published in peer-reviewed journals. The WHITE database has been very useful for descriptive epidemiological studies, monitoring health risk factors, benchmarking, and evaluating interventions.

    Previous observational measures of healthcare worker (HCW) hand-hygiene behaviour (HHB) fail to provide adequate standard operating procedures (SOPs), accounts of inter-rater agreement testing or evidence of sensitivity to change. This study reports the development of an observational tool in a way that addresses these deficiencies. Observational categories were developed systematically, guided by a clinical guideline, previous measures and pilot hand-hygiene behaviour observations (HHOs). The measure, a simpler version of the Geneva tool, consists of HHOs (before and after low-risk, high-risk or unobserved contact), HHBs (soap, alcohol hand rub, no action, unknown), and type of HCW. Inter-observer agreement for each category was assessed by observation of 298 HHOs and HHBs by two independent observers on acute elderly and intensive care units. Raw agreement (%) and Kappa were 77% and 0.68 for HHB; 83% and 0.77 for HHO; and 90% and 0.77 for HCW. Inter-observer agreement for overall compliance of a group of HCWs was assessed by observation of 1191 HHOs and HHBs by two pairs of independent observers. Overall agreement was good (intraclass correlation coefficient = 0.79). Sensitivity to change was examined by autoregressive time-series modelling of longitudinal observations for 8 months on the intensive therapy unit during an Acinetobacter baumannii outbreak and subsequent strengthening of infection control measures. Sensitivity to change was demonstrated by a rise in compliance from 80 to 98% with an odds ratio of increased compliance of 7.00 (95% confidence interval: 4.02-12.2) P < 0.001.

    Purpose To develop and validate case-finding algorithms for granulomatosis with polyangiitis (Wegener’s, GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (Churg-Strauss, EGPA). Methods 250 patients per disease were randomly selected from 2 large healthcare systems using the International Classification of Diseases version 9 (ICD9) codes for GPA/EGPA (446.4) and MPA (446.0). 16 case-finding algorithms were constructed using a combination of ICD9 code, encounter type (inpatient or outpatient), physician specialty, use of immunosuppressive medications, and the anti-neutrophil cytoplasmic antibody (ANCA) type. Algorithms with the highest average positive predictive value (PPV) were validated in a third healthcare system. Results An algorithm excluding patients with eosinophilia or asthma and including the encounter type and physician specialty had the highest PPV for GPA (92.4%). An algorithm including patients with eosinophilia and asthma and the physician specialty had the highest PPV for EGPA (100%). An algorithm including patients with one of the following diagnoses: alveolar hemorrhage, interstitial lung disease, glomerulonephritis, acute or chronic kidney disease, the encounter type, physician specialty, and immunosuppressive medications had the highest PPV for MPA (76.2%). When validated in a third healthcare system, these algorithms had high PPV (85.9% for GPA, 85.7% for EGPA, and 61.5% for MPA). Adding the ANCA type increased the PPV to 94.4%, 100%, and 81.2% for GPA, EGPA, and MPA respectively. Conclusion Case-finding algorithms accurately identify patients with GPA, EGPA, and MPA in administrative databases. These algorithms can be used to assemble population-based cohorts and facilitate future research in epidemiology, drug safety, and comparative effectiveness. PMID:27804171

The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and the National Inpatient Sample (NIS) are big databases that were developed in the USA in order to record surgical outcomes. The aim of the present systematic review is to evaluate the type and clinical impact of the information retrieved through NISQP and NIS big database articles focused on laparoscopic colorectal surgery. A systematic review was conducted using The Meta-Analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. The research was carried out on PubMed database and revealed 350 published papers. Outcomes of articles in which laparoscopic colorectal surgery was the primary aim were analyzed. Fifty-five studies, published between 2007 and February 2017, were included. Articles included were categorized in groups according to the main topic as: outcomes related to surgical technique comparisons, morbidity and perioperatory results, specific disease-related outcomes, sociodemographic disparities, and academic training impact. NSQIP and NIS databases are just the tip of the iceberg for the potential application of Big Data technology and analysis in MIS. Information obtained through big data is useful and could be considered as external validation in those situations where a significant evidence-based medicine exists; also, those databases establish benchmarks to measure the quality of patient care. Data retrieved helps to inform decision-making and improve healthcare delivery.

    Breast, lung and colorectal cancers constitute the most common cancers worldwide and their epidemiology, related health outcomes and quality indicators can be studied using administrative healthcare databases. To constitute a reliable source for research, administrative healthcare databases need to be validated. The aim of this protocol is to perform the first systematic review of studies reporting the validation of International Classification of Diseases 9th and 10th revision codes to identify breast, lung and colorectal cancer diagnoses in administrative healthcare databases. This review protocol has been developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P) 2015 statement. We will search the following databases: MEDLINE, EMBASE, Web of Science and the Cochrane Library, using appropriate search strategies. We will include validation studies that used administrative data to identify breast, lung and colorectal cancer diagnoses or studies that evaluated the validity of breast, lung and colorectal cancer codes in administrative data. The following inclusion criteria will be used: (1) the presence of a reference standard case definition for the disease of interest; (2) the presence of at least one test measure (eg, sensitivity, positive predictive values, etc) and (3) the use of data source from an administrative database. Pairs of reviewers will independently abstract data using standardised forms and will assess quality using a checklist based on the Standards for Reporting of Diagnostic accuracy (STARD) criteria. Ethics approval is not required. We will submit results of this study to a peer-reviewed journal for publication. The results will serve as a guide to identify appropriate case definitions and algorithms of breast, lung and colorectal cancers for researchers involved in validating administrative healthcare databases as well as for outcome research on these conditions that used administrative

    Two new precipitation retrieval algorithms for the Advanced Microwave Scanning Radiometer 2 (AMSR2) and for the GPM Microwave Imager (GMI) are presented. The algorithms are based on the Cloud Dynamics and Radiation Database (CDRD) Bayesian approach and represent an evolution of the previous version applied to Special Sensor Microwave Imager/Sounder (SSMIS) observations, and used operationally within the EUMETSAT Satellite Application Facility on support to Operational Hydrology and Water Management (H-SAF). These new products present as main innovation the use of an extended database entirely empirical, derived from coincident radar and radiometer observations from the NASA/JAXA Global Precipitation Measurement Core Observatory (GPM-CO) (Dual-frequency Precipitation Radar-DPR and GMI). The other new aspects are: 1) a new rain-no-rain screening approach; 2) the use of Empirical Orthogonal Functions (EOF) and Canonical Correlation Analysis (CCA) both in the screening approach, and in the Bayesian algorithm; 2) the use of new meteorological and environmental ancillary variables to categorize the database and mitigate the problem of non-uniqueness of the retrieval solution; 3) the development and implementations of specific modules for computational time minimization. The CDRD algorithms for AMSR2 and GMI are able to handle an extremely large observational database available from GPM-CO and provide the rainfall estimate with minimum latency, making them suitable for near-real time hydrological and operational applications. As far as CDRD for AMSR2, a verification study over Italy using ground-based radar data and over the MSG full disk area using coincident GPM-CO/AMSR2 observations has been carried out. Results show remarkable AMSR2 capabilities for rainfall rate (RR) retrieval over ocean (for RR > 0.25 mm/h), good capabilities over vegetated land (for RR > 1 mm/h), while for coastal areas the results are less certain.

    As nurses around the world prepare to celebrate the centenary of the death of Florence Nightingale in 2010 this paper reviews her work on using information, especially statistics, to analyze and manage patient care and links that to current developments in informatics. It then examines assistive technologies and how they may impact on nursing practice in the future and links these developments to the writings of Florence Nightingale. The paper concludes by suggesting that in progressing towards sustainable and ubiquitous healthcare informatics we need to study history in order to learn from the lessons of Florence Nightingale and other healthcare pioneers.

    Opportunities to leverage observational data for precision medicine research are hampered by underlying sources of bias and paucity of methods to handle resulting uncertainty. We outline an approach to account for bias in identifying comorbid associations between 2 rare genetic disorders and type 2 diabetes (T2D) by applying a positive and negative control disease paradigm. Association between 10 common and 2 rare genetic disorders [Hereditary Fructose Intolerance (HFI) and α-1 antitrypsin deficiency] and T2D was compared with the association between T2D and 7 negative control diseases with no established relationship with T2D in 4 observational databases. Negative controls were used to estimate how much bias and variance existed in datasets when no effect should be observed. Unadjusted association for common and rare genetic disorders and T2D was positive and variable in magnitude and distribution in all 4 databases. However, association between negative controls and T2D was 200% greater than expected indicating the magnitude and confidence intervals for comorbid associations are sensitive to systematic bias. A meta-analysis using this method demonstrated a significant association between HFI and T2D but not for α-1 antitrypsin deficiency. For observational studies, when covariate data are limited or ambiguous, positive and negative controls provide a method to account for the broadest level of systematic bias, heterogeneity, and uncertainty. This provides greater confidence in assessing associations between diseases and comorbidities. Using this approach we were able to demonstrate an association between HFI and T2D. Leveraging real-world databases is a promising approach to identify and corroborate potential targets for precision medicine therapies.

    Social marketing is an important tool in the delivery of healthcare services. For any healthcare programme or project to be successful, community/consumer participation is required. The four principles of social marketing can guide policymakers and healthcare providers to successfully plan and implement health programmes. To review the existing literature in order to project the benefits of social marketing in healthcare. A search of periodical literature by the author involving social marketing and marketing concepts in health was carried out. Items were identified initially through health-oriented indexing services such as Medline, Health STAR and Cinahl, using the identifiers "social marketing" and "marketing in health". An extensive search was also carried out on educational database ERIC. A literature review of various studies on social marketing indicated that the selection of the right product (according to the community need) at the right place, with the right strategy for promotion and at the right price yields good results. However, along with technical sustainability (product, price, promotion and place), financial sustainability, institutional sustainability and market sustainability are conducive factors for the success of social marketing. The purpose of this literature review was to ascertain the likely effectiveness of social marketing principles and approaches and behaviour change communication towards health promotion. It is important for all healthcare workers to understand and respond to the public's desires and needs and routinely use consumer research to determine how best to help the public to solve problems and realise aspirations. Social marketing can optimise public health by facilitating relationship-building with consumers and making their lives healthier.

    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).

    There are multiple nationally representative databases that support epidemiologic and outcomes research, and it is unknown whether an otolaryngology-specific resource would prove indispensable or superfluous. Therefore, our objective was to determine the feasibility of analyses in the National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS) databases as compared with the otolaryngology-specific Creating Healthcare Excellence through Education and Research (CHEER) database. Parallel analyses in 2 data sets. Ambulatory visits in the United States. To test a fixed hypothesis that could be directly compared between data sets, we focused on a condition with expected prevalence high enough to substantiate availability in both. This query also encompassed a broad span of diagnoses to sample the breadth of available information. Specifically, we compared an assessment of suspected risk factors for sensorineural hearing loss in subjects 0 to 21 years of age, according to a predetermined protocol. We also assessed the feasibility of 6 additional diagnostic queries among all age groups. In the NAMCS/NHAMCS data set, the number of measured observations was not sufficient to support reliable numeric conclusions (percentage standard error among risk factors: 38.6-92.1). Analysis of the CHEER database demonstrated that age, sex, meningitis, and cytomegalovirus were statistically significant factors associated with pediatric sensorineural hearing loss (P < .01). Among the 6 additional diagnostic queries assessed, NAMCS/NHAMCS usage was also infeasible; the CHEER database contained 1585 to 212,521 more observations per annum. An otolaryngology-specific database has added utility when compared with already available national ambulatory databases. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Narcolepsy with cataplexy is a rare disease with an estimated prevalence of 0.02% in European populations. Narcolepsy shares many features of rare disorders, in particular the lack of awareness of the disease with serious consequences for healthcare supply. Similar to other rare diseases, only a few European countries have registered narcolepsy cases in databases of the International Classification of Diseases or in registries of the European health authorities. A promising approach to identify disease-specific adverse health effects and needs in healthcare delivery in the field of rare diseases is to establish a distributed expert network. A first and important step is to create a database that allows collection, storage and dissemination of data on narcolepsy in a comprehensive and systematic way. Here, the first prospective web-based European narcolepsy database hosted by the European Narcolepsy Network is introduced. The database structure, standardization of data acquisition and quality control procedures are described, and an overview provided of the first 1079 patients from 18 European specialized centres. Due to its standardization this continuously increasing data pool is most promising to provide a better insight into many unsolved aspects of narcolepsy and related disorders, including clear phenotype characterization of subtypes of narcolepsy, more precise epidemiological data and knowledge on the natural history of narcolepsy, expectations about treatment effects, identification of post-marketing medication side-effects, and will contribute to improve clinical trial designs and provide facilities to further develop phase III trials. © 2016 European Sleep Research Society.

    In the recent years, medical and healthcare higher education institutions compile their curricula in different ways in order to cover all necessary topics and sections that the students will need to go through to success in their future clinical practice. A medical and healthcare curriculum consists of many descriptive parameters, which define statements of what, when, and how students will learn in the course of their studies. For the purpose of understanding a complicated medical and healthcare curriculum structure, we have developed a web-oriented platform for curriculum management covering in detail formal metadata specifications in accordance with the approved pedagogical background, namely outcome-based approach. Our platform provides a rich database that can be used for innovative detailed educational data analysis. In this contribution we would like to present how we used a proven process model as a way of increasing accuracy in solving individual analytical tasks with the available data. Moreover, we introduce an innovative approach on how to explore a dataset in accordance with the selected methodology. The achieved results from the selected analytical issues are presented here in clear visual interpretations in an attempt to visually describe the entire medical and healthcare curriculum.

    The purpose of this project is to develop and enhance the HITRAN molecular spectroscopic database and associated software to support the observational programs of the Earth Observing System (EOS). In particular, the focus is on the EOS projects: the Atmospheric Infrared Sounder (AIRS), the High-Resolution Dynamics Limb Sounder (HIRDLS), Measurements of Pollution in the Troposphere (MOPITT), the Tropospheric Emission Spectrometer (TES), and the Stratospheric Aerosol and Gas Experiment (SAGE III). The HITRAN program is also involved in the Ozone Monitoring Experiment (OMI). The data requirements of these programs in terms of spectroscopy are varied with respect to constituents being observed, required remote-sensing parameters, and spectral coverage. A general requisite is for additional spectral parameters and improvements to existing molecular bands sufficient for the simulation of the observations leading to retrieval of the atmospheric state. In addition, cross-section data for heavier molecular species must be expanded and made amenable to modeling in remote sensing. The effort in the project also includes developing software and distribution to make access, manipulation, and use of HITRAN functional to the EOS program.

    To report an analysis of the concept of safety climate in healthcare providers. Compliance with safe work practices is essential to patient safety and care outcomes. Analysing the concept of safety climate from the perspective of healthcare providers could improve understanding of the correlations between safety climate and healthcare provider compliance with safe work practices, thus enhancing quality of patient care. Concept analysis. The electronic databases of CINAHL, MEDLINE, PubMed and Web of Science were searched for literature published between 1995-2015. Searches used the keywords 'safety climate' or 'safety culture' with 'hospital' or 'healthcare'. The concept analysis method of Walker and Avant analysed safety climate from the perspective of healthcare providers. Three attributes defined how healthcare providers define safety climate: (1) creation of safe working environment by senior management in healthcare organisations; (2) shared perception of healthcare providers about safety of their work environment; and (3) the effective dissemination of safety information. Antecedents included the characteristics of healthcare providers and healthcare organisations as a whole, and the types of work in which they are engaged. Consequences consisted of safety performance and safety outcomes. Most studies developed and assessed the survey tools of safety climate or safety culture, with a minority consisting of interventional measures for improving safety climate. More prospective studies are needed to create interventional measures for improving safety climate of healthcare providers. This study is provided as a reference for use in developing multidimensional safety climate assessment tools and interventional measures. The values healthcare teams emphasise with regard to safety can serve to improve safety performance. Having an understanding of the concept of and interventional measures for safety climate allows healthcare providers to ensure the safety of their

    Medical records are a critical component of a patient's treatment. However, documentation of patient-related information is considered a secondary activity in the provision of healthcare services, often leading to incomplete medical records and patient data of low quality. Advances in information technology (IT) in the health system and registration of information in electronic health records (EHR) using speechto- text conversion software have facilitated service delivery. This narrative review is a literature search with the help of libraries, books, conference proceedings, databases of Science Direct, PubMed, Proquest, Springer, SID (Scientific Information Database), and search engines such as Yahoo, and Google. I used the following keywords and their combinations: speech recognition, automatic report documentation, voice to text software, healthcare, information, and voice recognition. Due to lack of knowledge of other languages, I searched all texts in English or Persian with no time limits. Of a total of 70, only 42 articles were selected. Speech-to-text conversion technology offers opportunities to improve the documentation process of medical records, reduce cost and time of recording information, enhance the quality of documentation, improve the quality of services provided to patients, and support healthcare providers in legal matters. Healthcare providers should recognize the impact of this technology on service delivery.

    This paper presents the results of a review of literature relating to knowledge transfer and exchange in healthcare. Treatment, planning and policy decisions in contemporary nursing and healthcare should be based on sound evidence wherever possible, but research knowledge remains generally underused. Knowledge transfer and exchange initiatives aim to facilitate the accessibility, application and production of evidence and may provide solutions to this challenge. This review was conducted to help inform the design and implementation of knowledge transfer and exchange activities for a large healthcare organization. Databases: ASSIA, Business Source Premier, CINAHL, PsychInfo, Medline and the Cochrane Database of Systematic Reviews. An integrative literature review was carried out including an extensive literature search. English language systematic reviews, literature reviews, primary quantitative and qualitative papers and grey literature of high relevance evaluating, describing or discussing knowledge transfer or exchange activities in healthcare were included for review (January 1990-September 2009). Thirty-three papers were reviewed (four systematic reviews, nine literature reviews, one environmental scan, nine empirical studies and ten case studies). Robust research into knowledge transfer and exchange in healthcare is limited. Analysis of a wide range of evidence indicates a number of commonly featured characteristics but further evaluation of these activities would benefit their application in facilitating evidence-based practice in nursing. © 2011 The Authors.

    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

    Inequality in access to quality healthcare is a major health policy challenge in many low- and middle-income countries. This study aimed to identify the major sources of inequity in healthcare utilization using a population-based household survey from urban Nepal. A cross-sectional survey was conducted covering 9177 individuals residing in 1997 households in five municipalities of Kathmandu valley between 2011 and 2012. The concentration index was calculated and a decomposition method was used to measure inequality in healthcare utilization, along with a horizontal inequity index (HI) to estimate socioeconomic inequalities in healthcare utilization. Results showed a significant pro-rich distribution of general healthcare utilization in all service providers (Concentration Index: 0.062, P < 0.001; HI: 0.029, P < 0.05) and private service providers (Concentration Index: 0.070, P < 0.001; HI: 0.030, P < 0.05). The pro-rich distribution of probability in general healthcare utilization was attributable to inequalities in the level of household economic status (percentage contribution: 67.8%) and in the self-reported prevalence of non-communicable diseases such as hypertension (36.7%) and diabetes (14.4%). Despite the provision of free services by public healthcare providers, our analysis found no evidence of the poor making more use of public health services (Concentration Index: 0.041, P = 0.094). Interventions to reduce the household economic burden of major illnesses, coupled with improvement in the management of public health facilities, warrant further attention by policy-makers.

    2013-01-01

    Background Patient neglect is an issue of increasing public concern in Europe and North America, yet remains poorly understood. This is the first systematic review on the nature, frequency and causes of patient neglect as distinct from patient safety topics such as medical error. Method The Pubmed, Science Direct, and Medline databases were searched in order to identify research studies investigating patient neglect. Ten articles and four government reports met the inclusion criteria of reporting primary data on the occurrence or causes of patient neglect. Qualitative and quantitative data extraction investigated (1) the definition of patient neglect, (2) the forms of behaviour associated with neglect, (3) the reported frequency of neglect, and (4) the causes of neglect. Results Patient neglect is found to have two aspects. First, procedure neglect, which refers to failures of healthcare staff to achieve objective standards of care. Second, caring neglect, which refers to behaviours that lead patients and observers to believe that staff have uncaring attitudes. The perceived frequency of neglectful behaviour varies by observer. Patients and their family members are more likely to report neglect than healthcare staff, and nurses are more likely to report on the neglectful behaviours of other nurses than on their own behaviour. The causes of patient neglect frequently relate to organisational factors (e.g. high workloads that constrain the behaviours of healthcare staff, burnout), and the relationship between carers and patients. Conclusion A social psychology-based conceptual model is developed to explain the occurrence and nature of patient neglect. This model will facilitate investigations of i) differences between patients and healthcare staff in how they perceive neglect, ii) the association with patient neglect and health outcomes, iii) the relative importance of system and organisational factors in causing neglect, and iv) the design of interventions and

    Since 1994, the IAGOS program (In-Service Aircraft for a Global Observing System http://www.iagos.org) and its predecessor MOZAIC has produced in-situ measurements of the atmospheric composition during more than 46000 commercial aircraft flights. In order to help analyzing these observations and further understanding the processes driving their evolution, we developed a modelling tool SOFT-IO quantifying their source/receptor link. We improved the methodology used by Stohl et al. (2003), based on the FLEXPART plume dispersion model, to simulate the contributions of anthropogenic and biomass burning emissions from the ECCAD database (http://eccad.aeris-data.fr) to the measured carbon monoxide mixing ratio along each IAGOS flight. Thanks to automated processes, contributions are simulated for the last 20 days before observation, separating individual contributions from the different source regions. The main goal is to supply add-value products to the IAGOS database showing pollutants geographical origin and emission type. Using this information, it may be possible to link trends in the atmospheric composition to changes in the transport pathways and to the evolution of emissions. This tool could be used for statistical validation as well as for inter-comparisons of emission inventories using large amounts of data, as Lagrangian models are able to bring the global scale emissions down to a smaller scale, where they can be directly compared to the in-situ observations from the IAGOS database.

    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.

  7. Using a Relational Database to Index Infectious Disease Information

    Mapping medical knowledge into a relational database became possible with the availability of personal computers and user-friendly database software in the early 1990s. To create a database of medical knowledge, the domain expert works like a mapmaker to first outline the domain and then add the details, starting with the most prominent features. The resulting “intelligent database” can support the decisions of healthcare professionals. The intelligent database described in this article contains profiles of 275 infectious diseases. Users can query the database for all diseases matching one or more specific criteria (symptom, endemic region of the world, or epidemiological factor). Epidemiological factors include sources (patients, water, soil, or animals), routes of entry, and insect vectors. Medical and public health professionals could use such a database as a decision-support software tool. PMID:20623018

  8. Emerging Trends in Healthcare Adoption of Wireless Body Area Networks.

    Real-time personal health monitoring is gaining new ground with advances in wireless communications. Wireless body area networks (WBANs) provide a means for low-powered sensors, affixed either on the human body or in vivo, to communicate with each other and with external telecommunication networks. The healthcare benefits of WBANs include continuous monitoring of patient vitals, measuring postacute rehabilitation time, and improving quality of medical care provided in medical emergencies. This study sought to examine emerging trends in WBAN adoption in healthcare. To that end, a systematic literature survey was undertaken against the PubMed database. The search criteria focused on peer-reviewed articles that contained the keywords "wireless body area network" and "healthcare" or "wireless body area network" and "health care." A comprehensive review of these articles was performed to identify adoption dimensions, including underlying technology framework, healthcare subdomain, and applicable lessons-learned. This article benefits healthcare technology professionals by identifying gaps in implementation of current technology and highlighting opportunities for improving products and services.

    This article reviews traditional and current perspectives on randomized, controlled trials (RCTs) and observational studies relative to the economic implications for public healthcare stakeholders. It takes an average of 17 years to bring 14% of original research into clinical practice. Results from high-quality observational studies may complement limited RCTs in primary and secondary literature bases, and enhance the incorporation of sound evidence-based guidelines. Observational findings from comprehensive medical databases may offer valuable clues on the effectiveness and relevance of public healthcare interventions. Major expenditures associated with RCTs relate to recruitment, inappropriate site selection, conduct and reporting. Application of business strategies and economic evaluation tools, in addition to the planning and conduct of RCTs, may enhance clinical trial site performances. Considering the strengths and limitations of each study type, clinical researchers should explore the contextual worthiness of either design in promulgating knowledge. They should focus on quality of conduct and reporting that may allow for the liberation of limited public and private clinical research funding.

    Whistle-blowing is an ethical activity that tries to end wrongdoing. Wrongdoing in healthcare varies from inappropriate behaviour to illegal action. Whistle-blowing can have negative consequences for the whistle-blower, often in the form of bullying or retribution. Despite the wrongdoing and negative tone of whistle-blowing, there is limited literature exploring them in healthcare. The aim was to describe possible wrongdoing in Finnish healthcare and to examine whistle-blowing processes described on the basis of the existing literature in healthcare as perceived by healthcare professionals. The study was a cross-sectional descriptive survey. The data were collected using the electronic questionnaire Whistle-blowing in Health Care and analysed statistically. Participants and research context: A total of 397 Finnish healthcare professionals participated, 278 of whom had either suspected or observed wrongdoing in healthcare, which established the data for this article. Ethical considerations: Ethical approval was obtained from the Ethics Committee of the University (20/2015). Permission to conduct the study was received according to the organisation's policies. Wrongdoing occurs in healthcare, as 96% of the participants had suspected and 94% had observed wrongdoing. Regarding the frequency, wrongdoing was suspected (57%) and observed (52%) more than once a month. Organisation-related wrongdoing was the most common type of wrongdoing (suspected 70%, observed 66%). In total, two whistle-blowing processes were confirmed in healthcare: (1) from suspicion to consequences occurred to 27%, and (2) from observation to consequences occurred to 37% of the participants. Wrongdoing occurs in healthcare quite frequently. Whistle-blowing processes were described based on the existing literature, but two separate processes were confirmed by the empirical data. More research is needed on wrongdoing and whistle-blowing on it in healthcare.

    The purpose of this project is to develop and enhance the HITRAN molecular spectroscopic database and associated software to support the observational programs of the Earth Observing System (EOS). In particular, the focus is on the EOS projects: the Atmospheric Infrared Sounder (AIRS), the High-Resolution Dynamics Limb Sounder (HIRDLS), Measurements of Pollution in the Troposphere (MOPITT), the Tropospheric Emission Spectrometer (TES), and the Stratospheric Aerosol and Gas Experiment (SAGE III). The data requirements of these programs in terms of spectroscopy are varied, but usually call for additional spectral parameters or improvements to existing molecular bands. In addition, cross-section data for heavier molecular species must be expanded and made amenable to modeling in remote sensing. The effort in the project also includes developing software and distribution to make access, manipulation, and use of HITRAN functional to the EOS program.

    Inequality in access to quality healthcare is a major health policy challenge in many low- and middle-income countries. This study aimed to identify the major sources of inequity in healthcare utilization using a population-based household survey from urban Nepal. A cross-sectional survey was conducted covering 9177 individuals residing in 1997 households in five municipalities of Kathmandu valley between 2011 and 2012. The concentration index was calculated and a decomposition method was used to measure inequality in healthcare utilization, along with a horizontal inequity index (HI) to estimate socioeconomic inequalities in healthcare utilization. Results showed a significant pro-rich distribution of general healthcare utilization in all service providers (Concentration Index: 0.062, P < 0.001; HI: 0.029, P < 0.05) and private service providers (Concentration Index: 0.070, P < 0.001; HI: 0.030, P < 0.05). The pro-rich distribution of probability in general healthcare utilization was attributable to inequalities in the level of household economic status (percentage contribution: 67.8%) and in the self-reported prevalence of non-communicable diseases such as hypertension (36.7%) and diabetes (14.4%). Despite the provision of free services by public healthcare providers, our analysis found no evidence of the poor making more use of public health services (Concentration Index: 0.041, P = 0.094). Interventions to reduce the household economic burden of major illnesses, coupled with improvement in the management of public health facilities, warrant further attention by policy-makers. © The Author 2016.

    Administrative databases are increasingly being used in cancer observational studies. Identifying incident cancer in these databases is crucial. This study aimed to develop algorithms to estimate cancer incidence by using health administrative databases and to examine the accuracy of the algorithms in terms of national cancer incidence rates estimated from registries. We identified a cohort of 463 033 participants on 1 January 2012 in the Echantillon Généraliste des Bénéficiaires (EGB; a representative sample of the French healthcare insurance system). The EGB contains data on long-term chronic disease (LTD) status, reimbursed outpatient treatments and procedures, and hospitalizations (including discharge diagnoses, and costly medical procedures and drugs). After excluding cases of prevalent cancer, we applied 15 algorithms to estimate the cancer incidence rates separately for men and women in 2012 and compared them to the national cancer incidence rates estimated from French registries by indirect age and sex standardization. The most accurate algorithm for men combined information from LTD status, outpatient anticancer drugs, radiotherapy sessions and primary or related discharge diagnosis of cancer, although it underestimated the cancer incidence (standardized incidence ratio (SIR) 0.85 [0.80-0.90]). For women, the best algorithm used the same definition of the algorithm for men but restricted hospital discharge to only primary or related diagnosis with an additional inpatient procedure or drug reimbursement related to cancer and gave comparable estimates to those from registries (SIR 1.00 [0.94-1.06]). The algorithms proposed could be used for cancer incidence monitoring and for future etiological cancer studies involving French healthcare databases. Copyright © 2017 John Wiley & Sons, Ltd.

    Contemporary biomedical databases include a wide range of information types from various observational and instrumental sources. Among the most important features that unite biomedical databases across the field are high volume of information and high potential to cause damage through data corruption, loss of performance, and loss of patient privacy. Thus, issues of data governance and privacy protection are essential for the construction of data depositories for biomedical research and healthcare. In this paper, we discuss various challenges of data governance in the context of population genome projects. The various challenges along with best practices and current research efforts are discussed through the steps of data collection, storage, sharing, analysis, and knowledge dissemination.

    Randomised clinical trials are the 'gold standard' for evaluating the effectiveness of healthcare interventions. However, successful recruitment of participants remains a key challenge for many trialists. In this paper, we present a conceptual framework for creating a digital, population-based database for the recruitment of asthma patients into future asthma trials in the UK. Having set up the database, the goal is to then make it available to support investigators planning asthma clinical trials. The UK Database of Asthma Research Volunteers will comprise a web-based front-end that interactively allows participant registration, and a back-end that houses the database containing participants' key relevant data. The database will be hosted and maintained at a secure server at the Asthma UK Centre for Applied Research based at The University of Edinburgh. Using a range of invitation strategies, key demographic and clinical data will be collected from those pre-consenting to consider participation in clinical trials. These data will, with consent, in due course, be linkable to other healthcare, social, economic, and genetic datasets. To use the database, asthma investigators will send their eligibility criteria for participant recruitment; eligible participants will then be informed about the new trial and asked if they wish to participate. A steering committee will oversee the running of the database, including approval of usage access. Novel communication strategies will be utilised to engage participants who are recruited into the database in order to avoid attrition as a result of waiting time to participation in a suitable trial, and to minimise the risk of their being approached when already enrolled in a trial. The value of this database will be whether it proves useful and usable to researchers in facilitating recruitment into clinical trials on asthma and whether patient privacy and data security are protected in meeting this aim. Successful recruitment is

    PubMed

    2016-09-01

    Japan was once progressive in the digitalization of healthcare fields but unfortunately has fallen behind in terms of the secondary use of data for public interest. There has recently been a trend to establish large-scale health databases in the nation, and a conflict between data use for public interest and privacy protection has surfaced as this trend has progressed. Databases for health insurance claims or for specific health checkups and guidance services were created according to the law that aims to ensure healthcare for the elderly; however, there is no mention in the act about using these databases for public interest in general. Thus, an initiative for such use must proceed carefully and attentively. The PMDA projects that collect a large amount of medical record information from large hospitals and the health database development project that the Ministry of Health, Labour and Welfare (MHLW) is working on will soon begin to operate according to a general consensus; however, the validity of this consensus can be questioned if issues of anonymity arise. The likelihood that researchers conducting a study for public interest would intentionally invade the privacy of their subjects is slim. However, patients could develop a sense of distrust about their data being used since legal requirements are ambiguous. Nevertheless, without using patients' medical records for public interest, progress in medicine will grind to a halt. Proper legislation that is clear for both researchers and patients will therefore be highly desirable. A revision of the Act on the Protection of Personal Information is currently in progress. In reality, however, privacy is not something that laws alone can protect; it will also require guidelines and self-discipline. We now live in an information capitalization age. I will introduce the trends in legal reform regarding healthcare information and discuss some basics to help people properly face the issue of health big data and privacy

    Background Inspection systems are used in health care to promote quality improvements, i.e. to achieve changes in organisational structures or processes, healthcare provider behaviour and patient outcomes. These systems are based on the assumption that externally promoted adherence to evidence-based standards (through inspection/assessment) will result in higher quality of health care. However, the benefits of external inspection in terms of organisational, provider and patient level outcomes are not clear. Objectives To evaluate the effectiveness of external inspection of compliance with standards in improving healthcare organisation behaviour, healthcare professional behaviour and patient outcomes. Search methods We searched the following electronic databases for studies: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effectiveness, Scopus, HMIC, Index to Theses and Intute from their inception dates up to May 2011. There was no language restriction and studies were included regardless of publication status. We searched the reference lists of included studies and contacted authors of relevant papers, accreditation bodies and the International Organization for Standardisation (ISO), regarding any further published or unpublished work. Selection criteria We included randomised controlled trials (RCTs), controlled clinical trials (CCTs), interrupted time-series (ITSs) and controlled before and after studies (CBAs) evaluating the effect of external inspection against external standards on healthcare organisation change, healthcare professional behaviour or patient outcomes in hospitals, primary healthcare organisations and other community-based healthcare organisations. Data collection and analysis Two review authors independently applied eligibility criteria, extracted data and assessed the risk of bias of each included study. Since meta-analysis was

    2013-05-01

    This paper explores the implications that different technical strategies for sharing patient information have for healthcare workers and, as a consequence, for the extent to which these systems provide support for integrated care. Four technical strategies were identified and the forms of coupling they made with healthcare agencies were classified. A study was conducted in England to examine the human and organizational implications of systems implemented by these four strategies. Results were used from evaluation reports of two systems delivered as part of the NPfIT (National Programme for Information Technology) and from user responses to systems delivered in two local health communities in England. In the latter study 40 clinical respondents reported the use of systems to support integrated care in six healthcare pathways. The implementation of a detailed care record system (DCRS) in the NPfIT was problematic because it could not meet the diverse needs of all healthcare agencies and it required considerable local customization. The programme evolved to allow different systems to be delivered for each local health community. A national Summary Care Record (SCR) was implemented but many concerns were raised about wide access to confidential patient information. The two technical strategies that required looser forms of coupling and were under local control led to wide user adoption. The systems that enabled data to be transferred between local systems were successfully used to support integrated care in specific healthcare pathways. The portal approach gave many users an opportunity to view patient data held on a number of databases and this system evolved over a number of years as a result of requests from the user community. The UK national strategy to deliver single shared database systems requires tight coupling between many users and has led to poor adoption because of the diverse needs of healthcare agencies. Sharing patient information has been more

    The 'Tobacco, Exercise and Diet Messages' (TEXT ME) study was a 6-month, single-centre randomised clinical trial (RCT) that found a text message support program improved levels of cardiovascular risk factors in patients with coronary heart disease (CHD). The current analyses examined whether receipt of text messages influenced participants' engagement with conventional healthcare resources. The TEXT ME study database (N=710) was linked with routinely collected health department databases. Number of doctor consultations, investigations and cardiac medication prescriptions in the two study groups were compared. The most frequently accessed health service was consultations with a General Practitioner (mean 7.1, s.d. 5.4). The numbers of medical consultations, biochemical tests or cardiac-specific investigations were similar between the study groups. There was at least one prescription registered for statin, ACEI/ARBs and β-blockers in 79, 66 and 50% of patients respectively, with similar refill rates in both the study groups. The study identified TEXT ME text messaging program did not increase use of Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS) captured healthcare services. The observed benefits of TEXT ME reflect direct effects of intervention independent of conventional healthcare resource engagement.

    Recent papers have suggested that expanded combination antiretroviral treatment (cART) through lower viral load may be a strategy to reduce HIV transmission at a population level. We assessed calendar trends in detectable viral load in patients recruited to the Australian HIV Observational Database who were receiving cART. Patients were included in analyses if they had started cART (defined as three or more antiretrovirals) and had at least one viral load assessment after 1 January 1997. We analyzed detectable viral load (>400 copies/ml) in the first and second six months of each calendar year while receiving cART. Repeated measures logistic regression methods were used to account for within and between patient variability. Rates of detectable viral load were predicted allowing for patients lost to follow up. Analyses were based on 2439 patients and 31,339 viral load assessments between 1 January 1997 and 31 March 2009. Observed detectable viral load in patients receiving cART declined to 5.3% in the first half of 2009. Predicted detectable viral load based on multivariate models, allowing for patient loss to follow up, also declined over time, but at higher levels, to 13.8% in 2009. Predicted detectable viral load in Australian HIV Observational Database patients receiving cART declined over calendar time, albeit at higher levels than observed. However, over this period, HIV diagnoses and estimated HIV incidence increased in Australia.

    Medical database security is a particularly important issue for all Healthcare establishments. Medical information systems are intended to support a wide range of pertinent health issues today, for example: assure the quality of care, support effective management of the health services institutions, monitor and contain the cost of care, implement technology into care without violating social values, ensure the equity and availability of care, preserve humanity despite the proliferation of technology etc.. In this context, medical database security aims primarily to support: high availability, accuracy and consistency of the stored data, the medical professional secrecy and confidentiality, and the protection of the privacy of the patient. These properties, though of technical nature, basically require that the system is actually helpful for medical care and not harmful to patients. These later properties require in turn not only that fundamental ethical principles are not violated by employing database systems, but instead, are effectively enforced by technical means. This document reviews the existing and emerging work on the security of medical database systems. It presents in detail the related problems and requirements related to medical database security. It addresses the problems of medical database security policies, secure design methodologies and implementation techniques. It also describes the current legal framework and regulatory requirements for medical database security. The issue of medical database security guidelines is also examined in detailed. The current national and international efforts in the area are studied. It also gives an overview of the research work in the area. The document also presents in detail the most complete to our knowledge set of security guidelines for the development and operation of medical database systems.

    During the last decades, healthcare-associated genotypes of methicillin-resistant Staphylococcus epidermidis (HA-MRSE) have been established as important opportunistic pathogens. However, data on potential reservoirs on HA-MRSE is limited. The aim of the present study was to investigate the dynamics and to which extent HA-MRSE genotypes colonize patients, healthcare workers (HCWs) and the environment in an intensive care unit (ICU). Over 12 months in 2006-2007, swab samples were obtained from patients admitted directly from the community to the ICU and patients transferred from a referral hospital, as well as from HCWs, and the ICU environment. Patients were sampled every third day during hospitalization. Antibiotic susceptibility testing was performed according to EUCAST guidelines. Pulsed-field gel electrophoresis and multilocus sequence typing were used to determine the genetic relatedness of a subset of MRSE isolates. We identified 620 MRSE isolates from 570 cultures obtained from 37 HCWs, 14 patients, and 14 environmental surfaces in the ICU. HA-MRSE genotypes were identified at admission in only one of the nine patients admitted directly from the community, of which the majority subsequently were colonized by HA-MRSE genotypes within 3 days during hospitalization. Almost all (89%) of HCWs were nasal carriers of HA-MRSE genotypes. Similarly, a significant proportion of patients transferred from the referral hospital and fomites in the ICU were widely colonized with HA-MRSE genotypes. Patients transferred from a referral hospital, HCWs, and the hospital environment serve as important reservoirs for HA-MRSE. These observations highlight the need for implementation of effective infection prevention and control measures aiming at reducing HA-MRSE transmission in the healthcare setting.

    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.

    Internationally there is growing interest in the use of the arts in the healthcare context evidenced by the number of research studies reported in the nursing and medical literature. Establishing successful projects in healthcare environments will to some extent be reliant on the cooperation of staff working in these settings: healthcare professionals and their cultural values will be the lynchpin in the relationship between the artists organising the activities and the patients. This review appraises healthcare professionals' perceptions of the value of the arts in healthcare settings, and the impact of the arts on healthcare professionals. A critical review of the literature between 2004 and 2014 was undertaken. The following databases were searched: MedLine, CINAHL, AMED, Web of Science and ASSIA. Searches included words from three categories: arts activities; healthcare settings, and healthcare providers. Studies were included if they were written in English, explored the attitudes of healthcare professionals on the use of the arts in healthcare settings or the impact of arts activities on healthcare staff. Studies conducted in community venues and/or reporting on arts therapies (art, drama or music) were excluded. An initial 52 studies were identified and following screening for relevance and quality 27 articles were reviewed. Arts interventions were diverse and included music listening, visual arts, reading and creative writing, and dance. Despite some methodological limitations of the reviewed studies it was found that the majority of staff believed that engaging in arts interventions has a positive impact on patients' health and well-being. The findings suggest that arts interventions are perceived to have an impact on patients' stress, mood, pain levels, and sleep. Furthermore, staff believed that the arts can enhance communication between staff and patients, helping to build rapport and strengthen interactions. The majority of reported staff outcomes were

    Although coaching is a popular approach for enhancing the quality of Tier 1 instruction, limited research has addressed observational measures specifically designed to focus coaching on evidence-based practices. This study explains the development of the prekindergarten (pre-k) Classroom Observation Tool (COT) designed for use in a data-based coaching model. We examined psychometric characteristics of the COT and explored how coaches and teachers used the COT goal-setting system. The study included 193 coaches working with 3,909 pre-k teachers in a statewide professional development program. Classrooms served 3 and 4 year olds (n = 56,390) enrolled mostly in Title I, Head Start, and other need-based pre-k programs. Coaches used the COT during a 2-hr observation at the beginning of the academic year. Teachers collected progress-monitoring data on children's language, literacy, and math outcomes three times during the year. Results indicated a theoretically supported eight-factor structure of the COT across language, literacy, and math instructional domains. Overall interrater reliability among coaches was good (.75). Although correlations with an established teacher observation measure were small, significant positive relations between COT scores and children's literacy outcomes indicate promising predictive validity. Patterns of goal-setting behaviors indicate teachers and coaches set an average of 43.17 goals during the academic year, and coaches reported that 80.62% of goals were met. Both coaches and teachers reported the COT was a helpful measure for enhancing quality of Tier 1 instruction. Limitations of the current study and implications for research and data-based coaching efforts are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    Worldwide healthcare delivery trends are undergoing a subtle paradigm shift--patient centered services as opposed to provider centered services and wellness maintenance as opposed to illness management. In this paper we present a Tele-Healthcare project TIDE--Tele-Healthcare Information and Diagnostic Environment. TIDE manifests an 'intelligent' healthcare environment that aims to ensure lifelong coverage of person-specific health maintenance decision-support services--i.e., both wellness maintenance and illness management services--ubiquitously available via the Internet/WWW. Taking on an all-encompassing health maintenance role--spanning from wellness to illness issues--the functionality of TIDE involves the generation and delivery of (a) Personalized, Pro-active, Persistent, Perpetual, and Present wellness maintenance services, and (b) remote diagnostic services for managing noncritical illnesses. Technically, TIDE is an amalgamation of diverse computer technologies--Artificial Intelligence, Internet, Multimedia, Databases, and Medical Informatics--to implement a sophisticated healthcare delivery infostructure.

  9. How 'healthy' are healthcare organizations? Exploring employee healthcare utilization rates among Dutch healthcare organizations.

    Occupational health and safety research rarely makes use of data on employee healthcare utilization to gain insight into the physical and mental health of healthcare staff. This paper aims to fill this gap by examining the prevalence of two relevant types of healthcare utilization among staff working in healthcare organizations: physical therapy and mental healthcare utilization. The paper furthermore explores what role employee and organizational characteristics play in explaining differences in healthcare utilization between organizations. A Dutch healthcare insurance company provided healthcare utilization records for a sample of 417 organizations employing 136,804 healthcare workers in the Netherlands. The results showed that there are large differences between and within healthcare industries when it comes to employee healthcare utilization. Multivariate regression analyses revealed that employee characteristics such as age and gender distributions, and healthcare industry, explain some of the variance between healthcare organizations. Nevertheless, the results of the analyses showed that for all healthcare utilization indicators there is still a large amount of unexplained variance. Further research into the subject of organizational differences in employee healthcare utilization is needed, as finding possibilities to influence employee health and subsequent healthcare utilization is beneficial to employees, employers and society as a whole.

    Most veteran research is conducted in Department of Veterans Affairs (VA) healthcare settings, although most veterans obtain healthcare outside the VA. Our objective was to determine the adequacy and relative contributions of Veterans Health Administration (VHA), Veterans Benefits Administration (VBA), and Department of Defense (DOD) administrative databases for representing the U.S. veteran population, using as an example the creation of a sampling frame for the National Survey of Women Veterans. In 2008, we merged the VHA, VBA, and DOD databases. We identified the number of unique records both overall and from each database. The combined databases yielded 925,946 unique records, representing 51% of the 1,802,000 U.S. women veteran population. The DOD database included 30% of the population (with 8% overlap with other databases). The VHA enrollment database contributed an additional 20% unique women veterans (with 6% overlap with VBA databases). VBA databases contributed an additional 2% unique women veterans (beyond 10% overlap with other databases). Use of VBA and DOD databases substantially expands access to the population of veterans beyond those in VHA databases, regardless of VA use. Adoption of these additional databases would enhance the value and generalizability of a wide range of studies of both male and female veterans.

    Background This paper presents an analysis of the main characteristics of the Gulf Cooperation Council’s (GCC) health financing systems and draws similarities and differences between GCC countries and other high-income and low-income countries, in order to provide recommendations for healthcare policy makers. The paper also illustrates some financial implications of the recent implementation of the Compulsory Employment-based Health Insurance (CEBHI) system in Saudi Arabia. Methods Employing a descriptive framework for the country-level analysis of healthcare financing arrangements, we compared expenditure data on healthcare from GCC and other developing and developed countries, mostly using secondary data from the World Health Organization health expenditure database. The analysis was supported by a review of related literature. Results There are three significant characteristics affecting healthcare financing in GCC countries: (i) large expatriate populations relative to the national population, which leads GCC countries to use different strategies to control expatriate healthcare expenditure; (ii) substantial government revenue, with correspondingly high government expenditure on healthcare services in GCC countries; and (iii) underdeveloped healthcare systems, with some GCC countries’ healthcare indicators falling below those of upper-middle-income countries. Conclusion Reforming the mode of health financing is vital to achieving equitable and efficient healthcare services. Such reform could assist GCC countries in improving their healthcare indicators and bring about a reduction in out-of-pocket payments for healthcare. PMID:23996348

    The aim of this study was to develop and validate case-finding algorithms for granulomatosis with polyangiitis (Wegener's, GPA), microscopic polyangiitis (MPA), and eosinophilic GPA (Churg-Strauss, EGPA). Two hundred fifty patients per disease were randomly selected from two large healthcare systems using the International Classification of Diseases version 9 (ICD9) codes for GPA/EGPA (446.4) and MPA (446.0). Sixteen case-finding algorithms were constructed using a combination of ICD9 code, encounter type (inpatient or outpatient), physician specialty, use of immunosuppressive medications, and the anti-neutrophil cytoplasmic antibody type. Algorithms with the highest average positive predictive value (PPV) were validated in a third healthcare system. An algorithm excluding patients with eosinophilia or asthma and including the encounter type and physician specialty had the highest PPV for GPA (92.4%). An algorithm including patients with eosinophilia and asthma and the physician specialty had the highest PPV for EGPA (100%). An algorithm including patients with one of the diagnoses (alveolar hemorrhage, interstitial lung disease, glomerulonephritis, and acute or chronic kidney disease), encounter type, physician specialty, and immunosuppressive medications had the highest PPV for MPA (76.2%). When validated in a third healthcare system, these algorithms had high PPV (85.9% for GPA, 85.7% for EGPA, and 61.5% for MPA). Adding the anti-neutrophil cytoplasmic antibody type increased the PPV to 94.4%, 100%, and 81.2% for GPA, EGPA, and MPA, respectively. Case-finding algorithms accurately identify patients with GPA, EGPA, and MPA in administrative databases. These algorithms can be used to assemble population-based cohorts and facilitate future research in epidemiology, drug safety, and comparative effectiveness. Copyright © 2016 John Wiley & Sons, Ltd.

  13. Large-scale Health Information Database and Privacy Protection*1

    2016-01-01

    Japan was once progressive in the digitalization of healthcare fields but unfortunately has fallen behind in terms of the secondary use of data for public interest. There has recently been a trend to establish large-scale health databases in the nation, and a conflict between data use for public interest and privacy protection has surfaced as this trend has progressed. Databases for health insurance claims or for specific health checkups and guidance services were created according to the law that aims to ensure healthcare for the elderly; however, there is no mention in the act about using these databases for public interest in general. Thus, an initiative for such use must proceed carefully and attentively. The PMDA*2 projects that collect a large amount of medical record information from large hospitals and the health database development project that the Ministry of Health, Labour and Welfare (MHLW) is working on will soon begin to operate according to a general consensus; however, the validity of this consensus can be questioned if issues of anonymity arise. The likelihood that researchers conducting a study for public interest would intentionally invade the privacy of their subjects is slim. However, patients could develop a sense of distrust about their data being used since legal requirements are ambiguous. Nevertheless, without using patients’ medical records for public interest, progress in medicine will grind to a halt. Proper legislation that is clear for both researchers and patients will therefore be highly desirable. A revision of the Act on the Protection of Personal Information is currently in progress. In reality, however, privacy is not something that laws alone can protect; it will also require guidelines and self-discipline. We now live in an information capitalization age. I will introduce the trends in legal reform regarding healthcare information and discuss some basics to help people properly face the issue of health big data and privacy

    The advantages of the astronaut photography during Space Shuttle missions are briefly examined, and the scope and applications of the Space Shuttle earth observations photography database are discussed. The global and multidisciplinary nature of the data base is illustrated by several examples of geologic applications. These include the eruption of Mount Pinatubo (Philippine Islands), heat flow and ice cover on Lake Baikal in Siberia (Russia), and windblown dust in South America. It is noted that hand-held photography from the U.S. Space Shuttle provides unique remotely-sensed data for geologic applications because of the combination of varying perspectives, look angles, and illumination, and changing resolution resulting from different lenses and altitudes.

      Point of care resources make it easier for clinicians to find answers to questions that arise during a clinical encounter. In order to make informed purchase decisions in times of tight budgets, librarians need to have a better understanding of which resources will meet their patrons' clinical information needs.   The goal of this study was to assess the content, interface and usability of three point-of-care tools: BMJ Point-of-Care, Clin-eguide and Nursing Reference Centre.   A questionnaire designed to gather quantitative and qualitative data was created using Survey Monkey. The survey was distributed to healthcare practitioners in Alberta's two largest health regions, and the data were analysed for emergent themes.   The themes that arose--ease of use, validated content, relevancy to practice--generally echoed those stated in the literature. No one database fared significantly better, due to differing features, content and client preference.   Despite the limitations of the survey, the themes that emerged provide a springboard for future research on the efficacy of information resources used at the point of care, and the need for deeper analysis of these recent additions to the medical information market. © 2010 The authors.

    Family planning has been defined in the framework of mothers and children plan as one of Primary Healthcare (PHC) details. Besides quantity, the quality of services, particularly in terms of ethics, such as observing individuals' privacy, is of great importance in offering family planning services. A preliminary study to gather information about the degree of medical ethics offered during family planning services at Tehran urban healthcare centers. A questionnaire was designed for study. In the first question regarding informed consent, 47 clients who were advised about various contraception methods were asked whether advantages and disadvantages of the contraceptive methods have been discussed by the service provider. Then a certain rank was measured for either client or method in 2007. Finally, average value of advantage and disadvantage for each method was measured. In questions about autonomy, justice and beneficence, yes/no answers have been expected and measured accordingly. Health care providers have stressed more on the advantages of pills and disadvantages of tubectomy and have paid less attention to advantages of injection ampoules and disadvantages of pills in first time clients. While they have stressed more on the advantages and disadvantages of tubectomy and less attention to advantages of condom and disadvantages of vasectomy in second time clients. Clients divulged their 100% satisfaction in terms of observing turns and free charges services. Observance degree of autonomy was 64.7% and 77.3% for first time and second- time clients respectively. Applying the consultant's personal viewpoint for selecting a method will breach an informed consent for first and second time clients. System has good consideration to justice and no malfeasance.

    The technology and sophistication of healthcare utilization databases have expanded over the last decade to include results of lab tests, vital signs, and other clinical information. This review provides an assessment of the methodological and analytical challenges of conducting chronic obstructive pulmonary disease (COPD) outcomes research in a national electronic medical records (EMR) dataset and its potential application towards the assessment of national health policy issues, as well as a description of the challenges or limitations. An EMR database and its application to measuring outcomes for COPD are described. The ability to measure adherence to the COPD evidence-based practice guidelines, generated by the NIH and HEDIS quality indicators, in this database was examined. Case studies, before and after their publication, were used to assess the adherence to guidelines and gauge the conformity to quality indicators. EMR was the only source of information for pulmonary function tests, but low frequency in ordering by primary care was an issue. The EMR data can be used to explore impact of variation in healthcare provision on clinical outcomes. The EMR database permits access to specific lab data and biometric information. The richness and depth of information on "real world" use of health services for large population-based analytical studies at relatively low cost render such databases an attractive resource for outcomes research. Various sources of information exist to perform outcomes research. It is important to understand the desired endpoints of such research and choose the appropriate database source.

    To estimate the healthcare costs attributable to diabetes in Ontario, Canada using a propensity-matched control design and health administrative data from the perspective of a single-payer healthcare system. Incident diabetes cases among adults in Ontario were identified from the Ontario Diabetes Database between 2004 and 2012 and matched 1:3 to control subjects without diabetes identified in health administrative databases on the basis of sociodemographics and propensity score. Using a comprehensive source of administrative databases, direct per-person costs (Canadian dollars 2012) were calculated. A cost analysis was performed to calculate the attributable costs of diabetes; i.e. the difference of costs between patients with diabetes and control subjects without diabetes. The study sample included 699 042 incident diabetes cases. The costs attributable to diabetes were greatest in the year after diagnosis [C$3,785 (95% CI 3708, 3862) per person for women and C$3,826 (95% CI 3751, 3901) for men], increasing substantially for older age groups and patients who died during follow-up. After accounting for baseline comorbidities, attributable costs were primarily incurred through inpatient acute hospitalizations, physician visits and prescription medications and assistive devices. The excess healthcare costs attributable to diabetes are substantial and pose a significant clinical and public health challenge. This burden is an important consideration for decision-makers, particularly given increasing concern over the sustainability of the healthcare system, aging population structure and increasing prevalence of diabetic risk factors, such as obesity. © 2015 The Authors.

    Global healthcare practice has expanded in the past 20 years. At the same time the incorporation of research into the design process has gained prominence as a best practice among architects. The authors of this study investigated the status of design research in a variety of international settings. We intended to answer the question, "how pervasive is healthcare design research outside of the United States?" The authors reviewed the international literature on the design of healthcare facilities. More than 500 international studies and conference proceedings were incorporated in this literature review. A team of five research assistants searched multiple databases comparing approximately 16 keywords to geographic location. Some of those keywords included: evidence-based design, salutogenic design, design research, and healthcare environment. Additional articles were gathered by contacting prominent researchers and asking for their personal assessment of local health design research studies. While there are design researchers in most parts of the world, the majority of studies focus on the needs of populations in developed countries and generate guidelines that have significant cost and cultural implications that prohibit their implementation in developing countries. Additionally, the body of literature discussing the role of culture in healthcare environments is extremely limited. Design researchers must address the cultural implications of their studies. Additionally, we need to expand our research objectives to address healthcare design in countries that have not been previous considered. © 2014 Vendome Group, LLC.

    Measles transmission has been well documented in healthcare facilities. Healthcare personnel who are unvaccinated and who lack other evidence of measles immunity put themselves and their patients at risk for measles. We conducted a systematic literature review of measles vaccination policies and their implementation in healthcare personnel, measles seroprevalence among healthcare personnel, measles transmission and disease burden in healthcare settings, and impact/costs incurred by healthcare facilities for healthcare-associated measles transmission. Five database searches yielded 135 relevant articles; 47 additional articles were found through cross-referencing. The risk of acquiring measles is estimated to be 2 to 19 times higher for susceptible healthcare personnel than for the general population. Fifty-three articles published worldwide during 1989–2013 reported measles transmission from patients to healthcare personnel; many of the healthcare personnel were unvaccinated or had unknown vaccination status. Eighteen articles published worldwide during 1982–2013 described examples of transmission from healthcare personnel to patients or to other healthcare personnel. Half of European countries have no measles vaccine policies for healthcare personnel. There is no global policy recommendation for the vaccination of healthcare personnel against measles. Even in countries such as the United States or Finland that have national policies, the recommendations are not uniformly implemented in healthcare facilities. Measles serosusceptibility in healthcare personnel varied widely across studies (median 6.5%, range 0%-46%) but was consistently higher among younger healthcare personnel. Deficiencies in documentation of two doses of measles vaccination or other evidence of immunity among healthcare personnel presents challenges in responding to measles exposures in healthcare settings. Evaluating and containing exposures and outbreaks in healthcare settings can be

Disparities in accessing healthcare services and addressing healthcare needs are evident among ethnic minorities including Arab migrants, particularly, older people. Racial stereotyping can also affect their ability to use these services. Arabs are a populous and diverse group with a long history of global migration. Australia is one of the most multicultural societies in the world, and Arab-Australians constitute an important ethnic minority group. Systematic review. The electronic databases Academic Search Complete (EBSCO), MEDLINE (Ovid), Ageline, ProQuest, CINAHL, PubMed, PsychINFO and Google Scholar were searched from 1990-October 2012. Search terms included health care needs, aged care, ethnic, cultural, linguistics, social, ethnic groups, culturally and linguistically diverse, nonEnglish speaking, ageing, elderly, Arabs, Arabic-speaking and Australia. Eight articles reviewing the healthcare issues of Australians from Arabic-speaking background were identified using the search strategy. An additional eight articles were identified through hand searching. Racial stereotyping can alter health-seeking behaviours and healthcare treatment. Increasing the understanding of specific cultural attributes of Arab-Australians will contribute to improving health outcomes. Healthcare providers and policymakers need to adopt more effective ways of communication with Arab-Australians to provide more culturally competent care and achieve better health outcomes. © 2013 John Wiley & Sons Ltd.

    Facilitation of service user participation in the co-production of mental healthcare planning and service delivery is an integral component of contemporary mental health policy and clinical guidelines. However, many service users continue to experience exclusion from the planning of their care. This review synthesizes qualitative research about participation in mental healthcare and articulates essential processes that enable service user participation in mental health care. Electronic databases were systematically searched. Studies were included if they were peer reviewed qualitative studies, published between 2000 and 2015, examining participation in mental health care. The Critical Appraisal Skills Program checklist was used to assess the quality of each included study. Constant comparison was used to identify similar constructs across several studies, which were then abstracted into thematic constructs. The synthesis resulted in the identification of six principal themes, which articulate key processes that facilitate service user participation in mental healthcare. These themes included: exercising influence; tokenism; sharing knowledge; lacking capacity; respect; and empathy. This meta-synthesis demonstrates that service user participation in mental healthcare remains a policy aspiration, which generally has not been translated into clinical practice. The continued lack of impact on policy on the delivery of mental healthcare suggests that change may have to be community driven. Systemic service user advocacy groups could contribute critically to promoting authentic service user participation in the co-production of mental health services.

    A lack of non-technical skills is increasingly recognised as an important underlying cause of adverse events in healthcare. The nature and number of things professionals communicate to each other can be perceived as a product of their use of non-technical skills. This paper describes the development and reliability of an instrument to measure and quantify the use of non-technical skills by direct observations of explicit professional oral communication (EPOC) in the clinical situation. In an iterative process we translated, tested and refined an existing checklist from the aviation industry, called self, human interaction, aircraft, procedures and environment, in the context of healthcare, notably emergency departments (ED) and intensive care units (ICU). The EPOC comprises six dimensions: assertiveness, working with others; task-oriented leadership; people-oriented leadership; situational awareness; planning and anticipation. Each dimension is specified into several concrete items reflecting verbal behaviours. The EPOC was evaluated in four ED and six ICU. In the ED and ICU, respectively, 378 and 1144 individual and 51 and 68 contemporaneous observations of individual staff members were conducted. All EPOC dimensions occur frequently, apart from assertiveness, which was hardly observed. Intraclass correlations for the overall EPOC score ranged between 0.85 and 0.91 and for underlying EPOC dimensions between 0.53 and 0.95. The EPOC is a new instrument for evaluating the use of non-technical skills in healthcare, which is reliable in two highly different settings. By quantifying professional behaviour the instrument facilitates measurement of behavioural change over time. The results suggest that EPOC can also be translated to other settings.

    The Veterans Administration (VA) Healthcare system, containing hospital and community-based outpatient clinics, provides the setting for the study. Summary data was obtained from the VA Ambulatory Events Database for fiscal years (FY) 1997-2001 and in-depth data for FY 2001. In FY 2001, the database included approximately 4 million unique patients with 60 million encounters. The purpose of this study was: 1) to quantify injuries and use of services associated with falls among the elderly treated in Veterans Administration (VA) ambulatory care settings using administrative data; 2) to compare fall-related services provided to elderly veterans with those provided to younger veterans. Retrospective analysis of administrative data. This study describes the trends (FY 1997-2001) and patterns of fall-related ambulatory care encounters (FY 2001) in the VA Healthcare System. An approximately four-fold increase in both encounters and patients seen was observed in FY 1997-2001, largely paralleling the growth of VA ambulatory care services. More than two-thirds of the patients treated were found to be over the age of 65. Veterans over the age of 65 were found to be more likely to receive care in the non-urgent setting and had higher numbers of co-morbid conditions than younger veterans. While nearly half of the encounters occurred in the Emergency/Urgent Care setting, fall-related injuries led to services across a wide spectrum of medical and surgical providers/departments. This study represents the first attempt to use the VA Ambulatory Events Database to study fall-related services provided to elderly veterans. In view of the aging population served by the VA and the movement to provide increased services in the outpatient setting, this database provides an important resource for researchers and administrators interested in the prevention and treatment of fall-related injuries.

    2018-02-01

    In the last decade 'big data' has become a buzzword used in several industrial sectors, including but not limited to telephony, finance and healthcare. Despite its popularity, it is not always clear what big data refers to exactly. Big data has become a very popular topic in healthcare, where the term primarily refers to the vast and growing volumes of computerized medical information available in the form of electronic health records, administrative or health claims data, disease and drug monitoring registries and so on. This kind of data is generally collected routinely during administrative processes and clinical practice by different healthcare professionals: from doctors recording their patients' medical history, drug prescriptions or medical claims to pharmacists registering dispensed prescriptions. For a long time, this data accumulated without its value being fully recognized and leveraged. Today big data has an important place in healthcare, including in pharmacovigilance. The expanding role of big data in pharmacovigilance includes signal detection, substantiation and validation of drug or vaccine safety signals, and increasingly new sources of information such as social media are also being considered. The aim of the present paper is to discuss the uses of big data for drug safety post-marketing assessment.

The high levels of resistance to advertising and other forms of healthcare marketing by healthcare professionals has been largely based on the grounds that the practices are unethical. The nature of the resistance thus invites this exploration of healthcare marketing (and the marketing concept), marketing ethics, and the acceptance (rejection) by healthcare professionals of healthcare marketing.

    Coordination of healthcare effectively prevents exacerbations and reduces the number of hospitalizations, emergency visits, and the mortality rate in patients with chronic respiratory diseases. The purpose of this study was to determine clinical effectiveness of ambulatory healthcare coordination in chronic respiratory patients and its effect on the level of healthcare services as an indicator of direct medical costs. We conducted a retrospective health record survey, using an online database of 550 patients with chronic respiratory diseases. There were decreases in breathing rate, heart rate, and the number of cigarettes smoked per day, and forced vital capacity (FVC) and forced expired volume in 1 s (FEV1) increased after the implementation of the coordinated healthcare structure. These benefits were accompanied by increases in the number of visits to the pulmonary outpatient clinic (p < 0.001), diagnostic costs (p < 0.001), and referrals to other outpatient clinics (p < 0.003) and hospitals (p < 0.001). The advantageous effects of healthcare coordination on clinical status of respiratory patients above outlined persisted over a 3-year period being reviewed.

    Background Controversy exists over the true therapeutic equivalence of branded and generic levothyroxine—the drug of choice for treating hypothyroidism—so professional societies recommend against switching between different formulations of the drug and suggest that patients who do switch be monitored. Payers typically encourage switching to generic drugs because of lower drug acquisition costs. Objective To evaluate the impact of switching levothyroxine formulations on actual healthcare costs. Methods Patients with hypothyroidism and at least 6 months of branded levothyroxine therapy were identified from a large healthcare claims database. Patients who subsequently switched to another levothyroxine formulation and could be followed for 6 months postswitch were matched to demographically similar patients who were continuous users of branded levothyroxine. Pre- and postswitch healthcare costs for each group were compared. Results The savings in prescription drug costs after switching from branded to generic levothyroxine are offset by increases in costs for other healthcare services, such that switching is actually associated with an increase, not a decrease, in total healthcare costs. Conclusion In the absence of cost-savings, there is no clear rationale for switching patients from brand to generic levothyroxine. PMID:25126314

    This paper presents an analysis of the main characteristics of the Gulf Cooperation Council's (GCC) health financing systems and draws similarities and differences between GCC countries and other high-income and low-income countries, in order to provide recommendations for healthcare policy makers. The paper also illustrates some financial implications of the recent implementation of the Compulsory Employment-based Health Insurance (CEBHI) system in Saudi Arabia. Employing a descriptive framework for the country-level analysis of healthcare financing arrangements, we compared expenditure data on healthcare from GCC and other developing and developed countries, mostly using secondary data from the World Health Organization health expenditure database. The analysis was supported by a review of related literature. There are three significant characteristics affecting healthcare financing in GCC countries: (i) large expatriate populations relative to the national population, which leads GCC countries to use different strategies to control expatriate healthcare expenditure; (ii) substantial government revenue, with correspondingly high government expenditure on healthcare services in GCC countries; and (iii) underdeveloped healthcare systems, with some GCC countries' healthcare indicators falling below those of upper-middle-income countries. Reforming the mode of health financing is vital to achieving equitable and efficient healthcare services. Such reform could assist GCC countries in improving their healthcare indicators and bring about a reduction in out-of-pocket payments for healthcare. © 2013 The Authors.

    Each encounter of asymptomatic individuals with the healthcare system presents an opportunity for improvement of cardiovascular disease (CVD) awareness and sudden cardiac death (SCD) risk assessment. ECG sign deep terminal negativity of the P wave in V1 (DTNP V1 ) was shown to be associated with an increased risk of SCD in the general population. To evaluate association of DTNP V1 with all-cause mortality and newly diagnosed atrial fibrillation (AFib) in the large tertiary healthcare system patient population. Retrospective double cohort study compared two levels of exposure (automatically measured amplitude of P-prime (Pp) in V1): DTNP V1 (Pp from -100μV to -200μV) and ZeroPpV1 (Pp=0). An entire healthcare system (2010-2014) ECG database was screened. Medical records of children and patients with previously diagnosed AFib/atrial flutter (AFl), implanted pacemaker or cardioverter-defibrillator were excluded. DTNP V1 (n=3,413) and ZeroPpV1 (n=3,405) cohorts were matched by age and sex. Primary outcome was all-cause mortality. Secondary outcomes were newly diagnosed AFib/AFl. Median follow-up was 2.5 y. DTNP V1 was associated with all-cause mortality (HR 1.95(1.64-2.31); P<0.0001) and newly diagnosed AFib (HR 1.29(1.04-1.59); P=0.021) after adjustment for CVD, comorbidities, other ECG parameters, medications, and index ECG referral. Index ECG referral by a cardiologist was independently associated with 34% relative risk reduction of mortality (HR 0.66(0.52-0.84); P=0.001), as compared to ECG referral by a non-cardiologist. DTNP V1 is independently associated with twice higher risk of all-cause death, as compared to patients without P prime in V1. Life-saving effect of the index ECG referral by a cardiologist requires further study. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Patient aggression affects healthcare quality and, in extreme situations, may even lead to medical malpractice. Little is known, however, about the specific distribution of health care professionals' exposure to patient aggression in various countries. The aim of this study was to assess the exposure of various professional groups of healthcare personnel to patient aggression, and to identify potential determinants (medical profession, age, gender, professional experience and employment at outpatient/inpatient healthcare units) of this exposure. The study was performed between January 2008 - December 2009 in northeastern Poland, and included 1,624 healthcare workers (493 nurses, 504 midwives, 501 physicians and 126 medical rescue workers). Exposure to eight forms of patient aggression was assessed using the MDM Mobbing Questionnaire. Using a raised voice was the most frequently observed form of aggression in all groups, whereas the least frequent form of aggression encountered was the use of direct physical violence. In inpatient healthcare units, the intensity of patient aggression was encountered most by nurses and medical rescue workers, followed by physicians and midwives. In outpatient healthcare units, medical rescue workers experienced significantly higher levels of aggression when compared to other professional groups. Significant differences in mean aggression intensity experienced in inpatient and outpatient healthcare units were observed only in nurses and physicians. Furthermore, no significant effects of gender were observed on the intensity of patient aggression. Nurses are most exposed to different forms of patient aggression, with verbal attacks being most prevalent. Nurses employed at inpatient healthcare units experienced aggression more frequently than those working in outpatient healthcare units.

    New technologies, which constantly become available for mutation detection and gene analysis, have contributed to an exponential rate of discovery of disease genes and variation in the human genome. The task of collecting and documenting this enormous amount of data in genetic databases represents a major challenge for the future of biological and medical science. The Locus Specific Databases (LSDBs) are so far the most efficient mutation databases. This review presents the main types of databases available for the analysis of mutations responsible for genetic disorders, as well as open perspectives for new therapeutic research or challenges for future medicine. Accurate and exhaustive collection of variations in human genomes will be crucial for research and personalized delivery of healthcare. Copyright © 2009 Elsevier Masson SAS. All rights reserved.

    Administrative healthcare databases are useful to investigate the epidemiology, health outcomes, quality indicators and healthcare utilisation concerning peptic ulcers and gastrointestinal bleeding, but the databases need to be validated in order to be a reliable source for research. The aim of this protocol is to perform the first systematic review of studies reporting the validation of International Classification of Diseases, 9th Revision and 10th version (ICD-9 and ICD-10) codes for peptic ulcer and upper gastrointestinal bleeding diagnoses. MEDLINE, EMBASE, Web of Science and the Cochrane Library databases will be searched, using appropriate search strategies. We will include validation studies that used administrative data to identify peptic ulcer disease and upper gastrointestinal bleeding diagnoses or studies that evaluated the validity of peptic ulcer and upper gastrointestinal bleeding codes in administrative data. The following inclusion criteria will be used: (a) the presence of a reference standard case definition for the diseases of interest; (b) the presence of at least one test measure (eg, sensitivity, etc) and (c) the use of an administrative database as a source of data. Pairs of reviewers will independently abstract data using standardised forms and will evaluate quality using the checklist of the Standards for Reporting of Diagnostic Accuracy (STARD) criteria. This systematic review protocol has been produced in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA-P) 2015 statement. Ethics approval is not required given that this is a protocol for a systematic review. We will submit results of this study to a peer-reviewed journal for publication. The results will serve as a guide for researchers validating administrative healthcare databases to determine appropriate case definitions for peptic ulcer disease and upper gastrointestinal bleeding, as well as to perform outcome research using

    This paper examines healthcare utilization behaviour in Sri Lanka with special emphasis on the choice between costly private and free public healthcare services. We use a data set that combines nationwide household survey data and district level healthcare supply data. Our findings suggest that even with universal public healthcare policy, richer people tend to use private sector healthcare services rather than public services. We also find significant regional and ethnic discrepancies in healthcare access bearing the risk of social tensions if these are further amplified. Latent class analysis shows in addition that the choice between private and public sector healthcare significantly differs between people with and without chronic diseases. We find in particular that chronically ill people rely for their day-to-day care on the public sector, but for their inpatient care they turn more often than non-chronically ill people to the private sector, implying an additional financial burden for the chronically ill. If the observed trend continues it may not only increase further the health-income gradient in Sri Lanka but also undermine the willingness of the middle class to pay taxes to finance public healthcare. © The Author 2017.

    Haile, Michael; Anderson, Kim; Evans, Alex; Crawford, Angela

    2012-01-01

    In part 1 of this series, we outlined the rationale behind the development of a centralized electronic database used to maintain nonsterile compounding formulation records in the Mission Health System, which is a union of several independent hospitals and satellite and regional pharmacies that form the cornerstone of advanced medical care in several areas of western North Carolina. Hospital providers in many healthcare systems require compounded formulations to meet the needs of their patients (in particular, pediatric patients). Before a centralized electronic compounding database was implemented in the Mission Health System, each satellite or regional pharmacy affiliated with that system had a specific set of formulation records, but no standardized format for those records existed. In this article, we describe the quality control, database platform selection, description, implementation, and execution of our intranet database system, which is designed to maintain, manage, and disseminate nonsterile compounding formulation records in the hospitals and affiliated pharmacies of the Mission Health System. The objectives of that project were to standardize nonsterile compounding formulation records, create a centralized computerized database that would increase healthcare staff members' access to formulation records, establish beyond-use dates based on published stability studies, improve quality control, reduce the potential for medication errors related to compounding medications, and (ultimately) improve patient safety.

    Percutaneous coronary intervention (PCI) is the most commonly used procedure for coronary revascularization. There are multiple adjuvant anticoagulation strategies available. In this era of cost containment, we performed a comparative effectiveness analysis of clinical outcomes and cost of the major anticoagulant strategies across all types of PCI procedures in a large observational database. A retrospective, comparative effectiveness analysis of the Premier observational database was conducted to determine the impact of anticoagulant treatment on outcomes. Multiple linear regression and logistic regression models were used to assess the association of initial antithrombotic treatment with outcomes while controlling for other factors. A total of 458,448 inpatient PCI procedures with known antithrombotic regimen from 299 hospitals between January 1, 2004 and March 31, 2008 were identified. Compared to patients treated with heparin plus glycoprotein IIb/IIIa inhibitor (GPI), bivalirudin was associated with a 41% relative risk reduction (RRR) for inpatient mortality, a 44% RRR for clinically apparent bleeding, and a 37% RRR for any transfusion. Furthermore, treatment with bivalirudin alone resulted in a cost savings of $976 per case. Similar results were seen between bivalirudin and heparin in all end-points. Combined use of both bivalirudin and GPI substantially attenuated the cost benefits demonstrated with bivalirudin alone. Bivalirudin use was associated with both improved clinical outcomes and decreased hospital costs in this large "real-world" database. To our knowledge, this study is the first to demonstrate the ideal comparative effectiveness end-point of both improved clinical outcomes with decreased costs in PCI. ©2012, Wiley Periodicals, Inc.

    The goal of the Eggen Card Database Project is to recover as many of the photometric observations from Olin Eggen's Card Database as possible and preserve these observations, in digital forms that are accessible by anyone. Any observations of interest to the AAVSO will be added to the AAVSO International Database (AID). Given to the AAVSO on long-term loan by the Cerro Tololo Inter-American Observatory, the database is a collection of over 78,000 index cards holding all Eggen's observations made between 1960 and 1990. The cards were electronically scanned and the resulting 108,000 card images have been published as a series of 2,216 PDF files, which are available from the AAVSO web site. The same images are also stored in an AAVSO online database where they are indexed by star name and card content. These images can be viewed using the eggen card portal online tool. Eggen made observations using filter bands from five different photometric systems. He documented these observations using 15 different data recording formats. Each format represents a combination of filter magnitudes and color indexes. These observations are being transcribed onto spreadsheets, from which observations of value to the AAVSO are added to the AID. A total of 506 U, B, V, R, and I observations were added to the AID for the variable stars S Car and l Car. We would like the reader to search through the card database using the eggen card portal for stars of particular interest. If such stars are found and retrieval of the observations is desired, e-mail the authors, and we will be happy to help retrieve those data for the reader.

    To present the successful experiences of an integrated, collaborative, distributed, large-scale enterprise healthcare information system over a wired and wireless infrastructure in National Taiwan University Hospital (NTUH). In order to smoothly and sequentially transfer from the complex relations among the old (legacy) systems to the new-generation enterprise healthcare information system, we adopted the multitier framework based on service-oriented architecture to integrate the heterogeneous systems as well as to interoperate among many other components and multiple databases. We also present mechanisms of a logical layer reusability approach and data (message) exchange flow via Health Level 7 (HL7) middleware, DICOM standard, and the Integrating the Healthcare Enterprise workflow. The architecture and protocols of the NTUH enterprise healthcare information system, especially in the Inpatient Information System (IIS), are discussed in detail. The NTUH Inpatient Healthcare Information System is designed and deployed on service-oriented architecture middleware frameworks. The mechanisms of integration as well as interoperability among the components and the multiple databases apply the HL7 standards for data exchanges, which are embedded in XML formats, and Microsoft .NET Web services to integrate heterogeneous platforms. The preliminary performance of the current operation IIS is evaluated and analyzed to verify the efficiency and effectiveness of the designed architecture; it shows reliability and robustness in the highly demanding traffic environment of NTUH. The newly developed NTUH IIS provides an open and flexible environment not only to share medical information easily among other branch hospitals, but also to reduce the cost of maintenance. The HL7 message standard is widely adopted to cover all data exchanges in the system. All services are independent modules that enable the system to be deployed and configured to the highest degree of flexibility

    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.

    Small area variations in healthcare infrastructure may result in differences in early detection and outcomes for patients with rare diseases. It is our aim to provide a framework for evaluating small area variations in healthcare infrastructure on the diagnostics and health outcomes of rare diseases. We focus on administrative data as it allows (a) for relatively large sample sizes even though the prevalence of rare diseases is very low, and (b) makes it possible to link information on healthcare infrastructure to morbidity, mortality, and utilization. For identifying patients with a rare disease in a database, a combination of different classification systems has to be used due to usually multiple diseases sharing one ICD code. Outcomes should be chosen that are (a) appropriate for the disease, (b) identifiable and reliably coded in the administrative database, and (c) observable during the limited time period of the follow-up. Risk adjustment using summary scores of disease-specific or comprehensive risk adjustment instruments might be preferable over empirical weights because of the lower number of variables needed. The proposed framework will help to identify differences in time to diagnosis and treatment outcomes across areas in the context of rare diseases. Copyright © 2012 Elsevier Ireland Ltd.

    Big data analysis is receiving increasing attention in many industries, including healthcare. Visualization plays an important role not only in intuitively showing the results of data analysis but also in the whole process of collecting, cleaning, analyzing, and sharing data. This paper presents a procedure for the interactive visualization and analysis of healthcare data using Tableau as a business intelligence tool. Starting with installation of the Tableau Desktop Personal version 10.3, this paper describes the process of understanding and visualizing healthcare data using an example. The example data of colon cancer patients were obtained from health insurance claims in years 2012 and 2013, provided by the Health Insurance Review and Assessment Service. To explore the visualization of healthcare data using Tableau for beginners, this paper describes the creation of a simple view for the average length of stay of colon cancer patients. Since Tableau provides various visualizations and customizations, the level of analysis can be increased with small multiples, view filtering, mark cards, and Tableau charts. Tableau is a software that can help users explore and understand their data by creating interactive visualizations. The software has the advantages that it can be used in conjunction with almost any database, and it is easy to use by dragging and dropping to create an interactive visualization expressing the desired format.

    Sickness absence (SA) among healthcare workers is associated with occupational and non-occupational risk factors and impacts employee health, healthcare delivery and patient health. At the same time, healthcare is one of the employment sectors with the highest rates of work-related ill health in the UK. Musculoskeletal (MSK) and mental health (MH) issues are leading causes of SA, but there is a lack of research on how certain MSK/MH conditions impact on SA duration. The study aim is to determine differences in SA duration by MH and MSK disorders in healthcare employees. Survival analyses were used to estimate SA duration due to MSK and MH problems over 6 years, and Cox's proportional hazards models to determine the HRs of returning to work, using a bespoke Scottish health board database with over 53 000 SA events. SA duration and time to return-to-work (RTW) were estimated for employees by age, gender, job and health conditions. MSK and MH conditions accounted for 27% and 6% of all SA events and 23.7% and 19.5% of all days lost, respectively. Average SA duration was 43.5 days for MSK and 53.9 days for MH conditions. For MSK conditions, employees with low back or neck pain had the fastest RTW (median P 50 : 7 days), whereas employees absent due to depression took the longest (P 50 : 54 days). The most influential sociodemographic variables affecting RTW were age, gender and job category. Using a unique and rich database, we found significant differences in SA duration by presenting condition in healthcare workers. MH conditions, and depression specifically, accounted for the most working days' absence. Significant variations in duration were also observed for MSK conditions. Our findings can inform public health practitioners and healthcare managers of the most significant factors impacting MSK-related and MH-related SA to develop and implement tailored and targeted workplace interventions. © Article author(s) (or their employer(s) unless otherwise stated in the

    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

    As the nature of work becomes more complex, teams have become necessary to ensure effective functioning within organizations. The healthcare industry is no exception. As such, the prevalence of training interventions designed to optimize teamwork in this industry has increased substantially over the last 10 years (Weaver, Dy, & Rosen, 2014). Using Kirkpatrick's (1956, 1996) training evaluation framework, we conducted a meta-analytic examination of healthcare team training to quantify its effectiveness and understand the conditions under which it is most successful. Results demonstrate that healthcare team training improves each of Kirkpatrick's criteria (reactions, learning, transfer, results; d = .37 to .89). Second, findings indicate that healthcare team training is largely robust to trainee composition, training strategy, and characteristics of the work environment, with the only exception being the reduced effectiveness of team training programs that involve feedback. As a tertiary goal, we proposed and found empirical support for a sequential model of healthcare team training where team training affects results via learning, which leads to transfer, which increases results. We find support for this sequential model in the healthcare industry (i.e., the current meta-analysis) and in training across all industries (i.e., using meta-analytic estimates from Arthur, Bennett, Edens, & Bell, 2003), suggesting the sequential benefits of training are not unique to medical teams. Ultimately, this meta-analysis supports the expanded use of team training and points toward recommendations for optimizing its effectiveness within healthcare settings.

    Self-management in healthcare can allow patients managing their health data anytime and everywhere for prevention of chronic diseases. This study established a prototype of ubiquitous health management system (UHMS) with healthy diet control (HDC) for people who need services of metabolic syndrome healthcare in Taiwan. System infrastructure comprises of three portals and a database tier with mutually supportive components to achieve functionality of diet diaries, nutrition guides, and health risk assessments for self-health management. With the diet, nutrition, and personal health database, the design enables the analytical diagrams on the interactive interface to support a mobile application for diet diary, a Web-based platform for health management, and the modules of research and development for medical care. For database integrity, dietary data can be stored at offline mode prior to transformation between mobile device and server site at online mode. The UHMS-HDC was developed by open source technology for ubiquitous health management with personalized dietary criteria. The system integrates mobile, internet, and electronic healthcare services with the diet diary functions to manage healthy diet behaviors of users. The virtual patients were involved to simulate the self-health management procedure. The assessment functions were approved by capturing the screen snapshots in the procedure. The proposed system development was capable for practical intervention. This approach details the expandable framework with collaborative components regarding the self-developed UHMS-HDC. The multi-disciplinary applications for self-health management can support the healthcare professionals to reduce medical resources and improve healthcare effects for the patient who requires monitoring personal health condition with diet control. The proposed system can be practiced for intervention in the hospital. Copyright © 2017 Elsevier B.V. All rights reserved.

    Background A lack of non-technical skills is increasingly recognised as an important underlying cause of adverse events in healthcare. The nature and number of things professionals communicate to each other can be perceived as a product of their use of non-technical skills. This paper describes the development and reliability of an instrument to measure and quantify the use of non-technical skills by direct observations of explicit professional oral communication (EPOC) in the clinical situation. Methods In an iterative process we translated, tested and refined an existing checklist from the aviation industry, called self, human interaction, aircraft, procedures and environment, in the context of healthcare, notably emergency departments (ED) and intensive care units (ICU). The EPOC comprises six dimensions: assertiveness, working with others; task-oriented leadership; people-oriented leadership; situational awareness; planning and anticipation. Each dimension is specified into several concrete items reflecting verbal behaviours. The EPOC was evaluated in four ED and six ICU. Results In the ED and ICU, respectively, 378 and 1144 individual and 51 and 68 contemporaneous observations of individual staff members were conducted. All EPOC dimensions occur frequently, apart from assertiveness, which was hardly observed. Intraclass correlations for the overall EPOC score ranged between 0.85 and 0.91 and for underlying EPOC dimensions between 0.53 and 0.95. Conclusions The EPOC is a new instrument for evaluating the use of non-technical skills in healthcare, which is reliable in two highly different settings. By quantifying professional behaviour the instrument facilitates measurement of behavioural change over time. The results suggest that EPOC can also be translated to other settings. PMID:23412933

    Understanding the interplay between informal care and formal healthcare is important because it sheds light on the financial implications of such interactions and may result in different policies. On the basis of a major database on 532 Italian stroke patients enrolled in the period 2007-2008, we investigate whether the presence of a potential caregiver and the amount of informal care provided influences the use and the costs of healthcare services, and in particular rehabilitation, in the post-acute phase. Primary caregivers of stroke patients were interviewed at 3, 6 and 12 months after the acute event and use of healthcare and informal care were documented. The panel dataset included socio-demographic, clinical and economic data on patients and caregivers. A longitudinal log-linear model was applied to test the impact of informal care on total healthcare costs in the observation period. A double hurdle model was used to investigate the impact of informal care on rehabilitation costs. A total of 476 of stroke survivors in 44 hospitals were enrolled in the study and presence of informal caregiver was reported in approximately 50% of the sample (range 48.2-52.5% across the three periods). Healthcare costs at 12 months after the acute event are €5825 per patient, with rehabilitation costs amounting to €3985 (68.4%). Healthcare costs are significantly different between the patients with and without caregiver in all three periods. The presence of the caregiver is associated with 54.7% increase in direct healthcare costs (p < 0.01). Instead, the amount of informal care provided does not influence significantly direct healthcare costs. The presence of caregiver significantly increases the probability of access to rehabilitation services (β = 0.648, p = 0.039) while, once the decision on access is made, it doesn't influence the amount of services used. Our results suggest that informal caregivers facilitate or even promote the access to healthcare services

    "Big data", characterized by 'volume', 'velocity', 'variety', and 'veracity', being routinely collected in huge amounts of clinical and administrative healthcare-related data are becoming common and generating promising viewpoints for a better understanding of the complexity for medical situations. Taiwan National Health Insurance Research Database (NHIRD), one of large and comprehensive nationwide population reimbursement databases in the world, provides the strength of sample size avoiding selection and participation bias. Abundant with the demographics, clinical diagnoses, and capable of linking diverse laboratory and imaging information allowing for integrated analysis, NHIRD studies could inform us of the incidence, prevalence, managements, correlations and associations of clinical outcomes and diseases, under the universal coverage of healthcare used. Perioperative medicine has emerged as an important clinical research field over the past decade, moving the categorization of the specialty of "Anesthesiology and Perioperative Medicine". Many studies concerning perioperative medicine based on retrospective cohort analyses have been published in the top-ranked journal, but studies utilizing Taiwan NHIRD were still not fully visualized. As the prominent growth curve of NHIRD studies, we have contributed the studies covering surgical adverse outcomes, trauma, stroke, diabetes, and healthcare inequality, etc., to this ever growing field for the past five years. It will definitely become a trend of research using Taiwan NHIRD and contributing to the progress of perioperative medicine with the recruitment of devotion from more research groups and become a famous doctrine.

    To report on an analysis of the concept of the sustainability of healthcare innovations. While there have been significant empirical, theoretical and practical contributions made towards the development and implementation of healthcare innovations, there has been less attention paid to their sustainability. Yet many desired healthcare innovations are not sustained over the long term. There is a need to increase clarity around the concept of innovation sustainability to guide the advancement of knowledge on this topic. Concept analysis. We included literature reviews, theoretical and empirical articles, books and grey literature obtained through database searching (ABI/INFORM, Academic Search Complete, Business Source Complete, CINAHL, Embase, MEDLINE and Web of Science) from 1996-May 2014, reference harvesting and citation searching. We examined sources according to terms and definitions, characteristics, preconditions, outcomes and boundaries to evaluate the maturity of the concept. This concept is partially mature. Healthcare innovation sustainability remains a multi-dimensional, multi-factorial notion that is used inconsistently or ambiguously and takes on different meanings at different times in different contexts. We propose a broad conceptualization that consists of three characteristics: benefits, routinization or institutionalization, and development. We also suggest that sustained innovations are influenced by a variety of preconditions or factors, which are innovation-, context-, leadership- and process-related. Further conceptual development is essential to continue advancing our understanding of the sustainability of healthcare innovations, especially in nursing where this topic remains largely unexplored. © 2015 John Wiley & Sons Ltd.

    Leaders are essential in every organization to achieve patient safety and healthy work environments. Authentic leadership is a relational leadership style purported to promote healthy work environments that influence staff performance and organizational outcomes. Given recent growth in authentic leadership research in healthcare and the importance of new knowledge to inform leadership development, there is an obligation to determine what is known about the antecedents and outcomes of authentic leadership in healthcare settings and clarify mechanisms by which authentic leadership affects healthcare staff and patient outcomes. The aim of this systematic review was to examine the antecedents, mediators and outcomes associated with authentic leadership in healthcare. Systematic review. The search strategy included 11 electronic databases: ABI Inform Dateline, Academic Search Complete, Cochrane Database of Systematic Reviews, PubMed, CINAHL, Embase, ERIC, PsycINFO, Scopus, Web of Science, and ProQuest Dissertations & Theses. The search was conducted in January 2017. Published English-only quantitative research that examined the antecedents, mediators and outcomes of authentic leadership practices of leaders in healthcare settings was included. Quality assessment, data extractions, and analysis were completed on all included studies. Data extracted from included studies were analyzed through descriptive and narrative syntheses. Content analysis was used to group antecedents, outcomes and mediators into categories which were then compared to authentic leadership theory. 1036 titles and abstracts were screened yielding 136 manuscripts for full-text review which resulted in 21 included studies reported in 38 manuscripts. Significant associations between authentic leadership and 43 outcomes were grouped into two major themes: healthcare staff outcomes with 5 subthemes (personal psychological states, satisfaction with work, work environment factors, health & well-being, and

    Background The proportion of people living with HIV/AIDS in the ageing population (>50 years) is increasing. We aim to explore the relationship between older age and treatment outcomes in HIV-positive persons from the Asia-Pacific region. Methods Patients from the Australian HIV Observational Database (AHOD) and the TREAT Asia HIV Observational Database (TAHOD) were included in the analysis. We used survival methods to assess the association between older age and all-cause mortality, as well as time-to treatment modification. We used regression analyses to evaluate changes in CD4 counts after combination antiretroviral therapy (cART) initiation and determined the odds of detectable viral load, up to 24 months of treatment. Results A total of 7142 patients were included in these analyses (60% TAHOD, 40% AHOD), of which, 25% were >50 years old. In multivariable analyses those aged >50 were at least twice as likely to die as those aged 30-39 years [HR (50-59 years): 2.27, 95% CI: 1.34-3.83; HR (>60years) 4.28, 95% CI: 2.42-7.55]. The effect of older age on CD4 count changes was insignificant (p-trend=0.06). The odds of detectable viral load after cART initiation decreased with age (p-trend=<0.0001). The effect of older age on time-to first treatment modification was insignificant (p-trend=0.21). We found no statistically significant differences in outcomes between AHOD and TAHOD participants for all endpoints examined. Conclusion The associations between older age and typical patient outcomes in HIV-positive patients from the Asia-Pacific region are similar in AHOD and TAHOD. Our data indicate that ‘age-effects’ traverse the resource-rich and resource-limited divide and indicate that future ageing-related findings might be applicable to each setting. PMID:25407085

    The programme for fiscal consolidation in Greece has led to income decrease and several changes in health policy. In this context, this study aims to assess how economic crisis affected unmet healthcare needs in Greece. Time series analysis was performed for the years 2004 through 2011 using the EU-SILC database. The dependent variable was the percentage of people who had medical needs but did not use healthcare services. Median income, unemployment and time period were used as independent variables. We also compared self-reported unmet healthcare needs drawn from a national survey conducted in pre-crisis 2006 with a similar survey from 2011 (after the onset of the crisis). A common questionnaire was used in both years to assess unmet healthcare needs, including year of survey, gender, age, health status, chronic disease, educational level, income, employment, health insurance status, and prefecture. The outcome of interest was unmet healthcare needs due to financial reasons. Ordinary least squares, as well as logistic regression analysis were conducted to analyze the results. Unmet healthcare needs increased after the enactment of austerity measures, while the year of participation in the survey was significantly associated with unmet healthcare needs. Income, educational level, employment status, and having insurance, private or public, were also significant determinants of unmet healthcare needs due to financial reasons. The adverse economic environment has significantly affected unmet health needs. Therefore health policy actions and social policy measures are essential in order to mitigate the negative impact on access to healthcare services and health status.

    Objective: We explored the concept of design quality in relation to healthcare environments. In addition, we present a taxonomy that illustrates the wide range of terms used in connection with design quality in healthcare. Background: High-quality physical environments can promote health and well-being. Developments in healthcare technology and methodology put high demands on the design quality of care environments, coupled with increasing expectations and demands from patients and staff that care environments be person centered, welcoming, and accessible while also supporting privacy and security. In addition, there are demands that decisions about the design of healthcare architecture be based on the best available information from credible research and the evaluation of existing building projects. Method: The basic principles of Arksey and O’Malley’s model of scoping review design were used. Data were derived from literature searches in scientific databases. A total of 18 articles and books were found that referred to design quality in a healthcare context. Results: Design quality of physical healthcare environments involves three different themes: (i) environmental sustainability and ecological values, (ii) social and cultural interactions and values, and (iii) resilience of the engineering and building construction. Design quality was clarified herein with a definition. Conclusions: Awareness of what is considered design quality in relation to healthcare architecture could help to design healthcare environments based on evidence. To operationalize the concept, its definition must be clear and explicit and able to meet the complex needs of the stakeholders in a healthcare context, including patients, staff, and significant others.

    Effective leadership of healthcare professionals is critical for strengthening quality and integration of care. This study aimed to assess whether there exist an association between different leadership styles and healthcare quality measures. The search was performed in the Medline (National Library of Medicine, PubMed interface) and EMBASE databases for the time period 2004-2015. The research question that guided this review was posed as: "Is there any relationship between leadership style in healthcare settings and quality of care?" Eighteen articles were found relevant to our research question. Leadership styles were found to be strongly correlated with quality care and associated measures. Leadership was considered a core element for a well-coordinated and integrated provision of care, both from the patients and healthcare professionals.

    Healthcare providers have many health-related risk factors that might contribute to urolithiasis: a heavy workload, a stressful workplace, and an unhealthy quality of life. However, the urolithiasis risk in healthcare providers is not clear. Using Taiwan's National Health Insurance Research Database, we identified 50,226 physicians, 20,677 pharmacists, 122,357 nurses, and 25,059 other healthcare providers as the study cohort and then randomly selected an identical number of patients who are not healthcare providers (general population) as the comparison cohort for this study. Conditional logistical regression analysis was used to compare the urolithiasis risk between healthcare providers and comparisons. Physician specialty subgroups were also analyzed. Physicians had a lower urolithiasis risk than did the general population (adjusted odds ratio [AOR]: 0.682; 95 % confidence interval [CI]: 0.634-0.732) and other healthcare providers (AOR: 0.661; 95 % CI 0.588-0.742) after adjusting for hypertension, diabetes, hyperlipidemia, coronary artery disease, and residence location. For pharmacists, nurses, and other healthcare providers, the urolithiasis risk was not significantly different than that for general population. Subgroup analysis showed that surgeons and family medicine physicians had a lower urolithiasis risk than did physician comparisons (AOR: 0.778; 95 % CI: 0.630-0.962 and AOR: 0.737; 95 % CI: 0.564-0.962, respectively). Although job stress and heavy workloads affect physicians' health, physicians had a lower urolithiasis risk than did the general population and other healthcare providers. This might be attributable to their greater medical knowledge and access to healthcare. Our findings provide useful information for public health policy makers about the disease risks of healthcare providers.

    As an alternative to the existing software architectures that underpin the development of smart homes and ambient assisted living (AAL) systems, this work presents a database-centric architecture that takes advantage of active databases and in-database processing. Current platforms supporting AAL systems use database management systems (DBMSs) exclusively for data storage. Active databases employ database triggers to detect and react to events taking place inside or outside of the database. DBMSs can be extended with stored procedures and functions that enable in-database processing. This means that the data processing is integrated and performed within the DBMS. The feasibility and flexibility of the proposed approach were demonstrated with the implementation of three distinct AAL services. The active database was used to detect bed-exits and to discover common room transitions and deviations during the night. In-database machine learning methods were used to model early night behaviors. Consequently, active in-database processing avoids transferring sensitive data outside the database, and this improves performance, security and privacy. Furthermore, centralizing the computation into the DBMS facilitates code reuse, adaptation and maintenance. These are important system properties that take into account the evolving heterogeneity of users, their needs and the devices that are characteristic of smart homes and AAL systems. Therefore, DBMSs can provide capabilities to address requirements for scalability, security, privacy, dependability and personalization in applications of smart environments in healthcare.

    Purpose Individuals diagnosed with cancer close to death have low access to enrollment in palliative care programs. The purpose of this literature review was to assess the usefulness of pre-diagnostic comorbidity and healthcare utilization as indicators of late-stage colorectal cancer (CRC) diagnosis, to help with early identification of individuals who may benefit from palliative care. Methods A literature search was conducted in relevant databases using title/abstract terms which included “cancer,” “stage,” “diagnosis,” “determinants,” “predictors,” and “associated.” Included studies examined whether comorbidity and/or healthcare utilization had an impact on the stage at which CRC was diagnosed. A standardized data abstraction form was used to assess the eligibility of each study. Thirteen articles were included in the literature review. These studies were assessed and synthesized using qualitative methodology. Results We found much heterogeneity among study variables. The findings of this literature review point to the presence of comorbidity and non-emergent healthcare utilization as having no association with late-stage diagnosis. Conversely, emergency room presentation (ERP) was associated with late-stage diagnosis. Conclusions The results of this literature review did not find strong evidence to suggest that comorbidity and healthcare utilization are potential indicators of late-stage diagnosis. However, ERP may be useful as a flag for consideration of prompt referral to palliative care. Additional research is required to identify potential indicators of late-stage diagnosis that may be available in administrative databases, particularly in the area of healthcare utilization.

    Quality improvement (QI) requires systematic and continuous efforts to enhance healthcare services. A healthcare provider might wish to compare local statistics with those from other institutions in order to identify problems and develop intervention to improve the quality of care. However, the sharing of institution information may be deterred by institutional privacy as publicizing such statistics could lead to embarrassment and even financial damage. In this article, we propose a PRivacy-prEserving Cloud-assisted quality Improvement Service in hEalthcare (PRECISE), which aims at enabling cross-institution comparison of healthcare statistics while protecting privacy. The proposed framework relies on a set of state-of-the-art cryptographic protocols including homomorphic encryption and Yao’s garbled circuit schemes. By securely pooling data from different institutions, PRECISE can rank the encrypted statistics to facilitate QI among participating institutes. We conducted experiments using MIMIC II database and demonstrated the feasibility of the proposed PRECISE framework. PMID:26146645

    Local and traditional knowledge and community-based monitoring programs are increasingly being recognized as an important part of establishing an Arctic observing network, and understanding Arctic environmental change. The Seasonal Ice Zone Observing Network (SIZONet, http://www.sizonet.org) project has implemented an integrated program for observing seasonal ice in Alaska. Observation and analysis by local sea ice experts helps track seasonal and inter-annual variability of the ice cover and its use by coastal communities. The ELOKA project (http://eloka-arctic.org) is collaborating with SIZONet on the development of a community accessible, Web-based application for collecting and distributing local observations. The SIZONet project is dealing with complicated qualitative and quantitative data collected from a growing number of observers in different communities while concurrently working to design a system that will serve a wide range of different end users including Arctic residents, scientists, educators, and other stakeholders with a need for sea ice information. The benefits of linking and integrating knowledge from communities and university-based researchers are clear, however, development of an information system in this multidisciplinary, multi-participant context is challenging. Participants are geographically distributed, have different levels of technical expertise, and have varying goals for how the system will be used. As previously reported (Pulsifer et al. 2010), new technologies have been used to deal with some of the challenges presented in this complex development context. In this paper, we report on the challenges and innovations related to working as a multi-disciplinary software development team. Specifically, we discuss how Agile software development methods have been used in defining and refining user needs, developing prototypes, and releasing a production level application.

    The paper addresses Medical Hand Drawing Management System architecture and implementation. In the system, we developed four modules: hand drawing management module; patient medical records query module; hand drawing editing and upload module; hand drawing query module. The system adapts windows-based applications and encompasses web pages by ASP.NET hosting mechanism under web services platforms. The hand drawings implemented as files are stored in a FTP server. The file names with associated data, e.g. patient identification, drawing physician, access rights, etc. are reposited in a database. The modules can be conveniently embedded, integrated into any system. Therefore, the system possesses the hand drawing features to support daily medical operations, effectively improve healthcare qualities as well. Moreover, the system includes the printing capability to achieve a complete, computerized medical document process. In summary, the system allows web-based applications to facilitate the graphic processes for healthcare operations.

    There is ongoing concern whether switching between different antiepileptic drug (AED) products may compromise patient care. We systematically reviewed changes in healthcare utilization following AED switch. We searched MEDLINE and EMBASE databases (1980-October 2016) for studies that assessed the effect of AED switching in patients with epilepsy on outpatient visits, emergency room visits, hospitalization and hospital stay duration. A total of 14 articles met the inclusion criteria. All were retrospective studies. Four provided findings for specific AEDs only (lamotrigine, topiramate, phenytoin and divalproex), 9 presented pooled findings from multiple AEDs, and 1 study provided both specific (lamotrigine, topiramate, oxcarbazepine, and levetiracetam) and pooled findings. Three studies found an association between a switch of topiramate and an increase in healthcare utilization. Another three studies found that a brand-to-generic lamotrigine switch was not associated with an increased risk of emergently treated events (ambulance use, ER visits or hospitalization). The outcomes of the pooled AED switch studies were inconsistent; 5 studies reported an increased healthcare utilization while 5 studies did not. Studies that have examined the association between an AED switch and a change in healthcare utilization report conflicting findings. Factors that may explain these inconsistent outcomes include inter-study differences in the type of analysis undertaken (pooled vs individual AED data), the covariates used for data adjustment, and the type of switch examined. Future medical claim database studies employing a prospective design are encouraged to address these and other factors in order to enhance inter-study comparability and extrapolation of findings.

  6. Expert Search Strategies: The Information Retrieval Practices of Healthcare Information Professionals

    PubMed Central

    2017-01-01

    Background Healthcare information professionals play a key role in closing the knowledge gap between medical research and clinical practice. Their work involves meticulous searching of literature databases using complex search strategies that can consist of hundreds of keywords, operators, and ontology terms. This process is prone to error and can lead to inefficiency and bias if performed incorrectly. Objective The aim of this study was to investigate the search behavior of healthcare information professionals, uncovering their needs, goals, and requirements for information retrieval systems. Methods A survey was distributed to healthcare information professionals via professional association email discussion lists. It investigated the search tasks they undertake, their techniques for search strategy formulation, their approaches to evaluating search results, and their preferred functionality for searching library-style databases. The popular literature search system PubMed was then evaluated to determine the extent to which their needs were met. Results The 107 respondents indicated that their information retrieval process relied on the use of complex, repeatable, and transparent search strategies. On average it took 60 minutes to formulate a search strategy, with a search task taking 4 hours and consisting of 15 strategy lines. Respondents reviewed a median of 175 results per search task, far more than they would ideally like (100). The most desired features of a search system were merging search queries and combining search results. Conclusions Healthcare information professionals routinely address some of the most challenging information retrieval problems of any profession. However, their needs are not fully supported by current literature search systems and there is demand for improved functionality, in particular regarding the development and management of search strategies.

    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.

    The purpose of this paper is to contribute toward a deeper understanding of the new roles, responsibilities, and job characteristics of employees in Lean healthcare organizations. The paper is based on three cases studies of healthcare organizations that are regarded as successful examples of Lean applications in the healthcare context. Data were collected by methods including interviews, observations, and document studies. The implementation of Lean in healthcare settings has had a great influence on the roles, responsibilities, and job characteristics of the employees. The focus has shifted from healthcare professionals, where clinical autonomy and professional skills have been the guarding principles of patient care, to process improvement and teamwork. Different job characteristics may make it difficult to implement certain Lean practices in healthcare. Teamwork and decentralization of authority are examples of Lean practices that could be considered countercultural because of the strong professional culture and uneven power distribution, with doctors as the dominant decision makers. Teamwork, value flow orientation, and company-wide involvement in CI were associated with positive effects on the organizations' working environment, staff development, and organizational performance. In order to succeed with Lean healthcare, it is important to understand and recognize the differences in job characteristics between Lean manufacturing and healthcare. This paper provides insights into how Lean implementation changes the roles, responsibilities, and job characteristics of healthcare staff and the challenges and implications that may follow from this.

    Hospital Episode Statistics data are used for healthcare planning and hospital reimbursements. Reliability of these data is dependent on the accuracy of individual hospitals reporting Secondary Uses Service (SUS) which includes hospitalisation. The number and coding accuracy for Parkinson's disease hospital admissions at a tertiary centre in Birmingham was assessed. Retrospective, routine-data-based study. A retrospective electronic database search for all Parkinson's disease patients admitted to the tertiary hospital over a 4-year period (2009-2013) was performed on the SUS database using International Classification of Disease codes, and on the local inpatient electronic prescription database, Prescription and Information Communications System, using medication prescriptions. Capture-recapture methods were used to estimate the number of patients and admissions missed by both databases. From the two databases, between July 2009 and June 2013, 1068 patients with Parkinson's disease accounted for 1999 admissions. During these admissions, the Parkinson's disease was coded as a primary or secondary diagnosis. Ninety-one percent of these admissions were recorded on the SUS database. Capture-recapture methods estimated that the number of Parkinson's disease patients admitted during this period was 1127 patients (95% confidence interval: 1107-1146). A supplementary search of both SUS and Prescription and Information Communications System was undertaken using the hospital numbers of these 1068 patients. This identified another 479 admissions. SUS database under-estimated Parkinson's disease admissions by 27% during the study period. The accuracy of disease coding is critical for healthcare policy planning and must be improved. If the under-reporting of Parkinson's disease admissions on the SUS database is repeated nationally, expenditure on Parkinson's disease admissions in England is under-estimated by approximately £61 million per year.

    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

    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.

    Interactions between pharmaceutical companies and healthcare providers are increasingly scrutinized by academics, professionals, media, and politicians. Most empirical studies and professional guidelines focus on unilateral donor-recipient types of interaction and overlook, or fail to distinguish between, more reciprocal types of interaction. However, the degree of goal alignment and potential for value creation differs in these two types of interactions. Failing to differentiate between these two forms of interaction between pharmaceutical companies and healthcare providers could thus lead to biased conclusions regarding their desirability. This study reviews the empirical literature regarding the effects of bilateral forms of interactions between pharmaceutical companies and healthcare providers in order to explore their effects. We searched two medical databases (i.e. PubMed and Cochrane Library) and one business database (i.e. EBSCO) for empirical, peer-reviewed articles concerning any type of bilateral interaction between pharmaceutical companies and healthcare providers. We included quantitative articles which were written in English and published between January 1st, 2000 and October 31st, 2016, and where the title or abstract included a combination of synonyms of the following keywords: pharmaceutical companies, healthcare providers, interaction, and effects. Our search results yielded 10 studies which were included in our analysis. These studies focused on either research-oriented interaction or on education-oriented interaction. The included studies reported various outcomes of interaction such as prescribing behavior, ethical dilemmas, and research output. Regardless of the type of interaction, the studies either reported no significant effects or ambivalent outcomes such as affected clinical practice or ethical issues. The effects of bilateral interactions reported in the literature are similar to those reported in studies concerning unilateral

    Many existing healthcare information systems are composed of a number of heterogeneous systems and face the important issue of system scalability. This paper first describes the comprehensive healthcare information systems used in National Taiwan University Hospital (NTUH) and then presents a service-oriented architecture (SOA)-based healthcare information system (HIS) based on the service standard HL7. The proposed architecture focuses on system scalability, in terms of both hardware and software. Moreover, we describe how scalability is implemented in rightsizing, service groups, databases, and hardware scalability. Although SOA-based systems sometimes display poor performance, through a performance evaluation of our HIS based on SOA, the average response time for outpatient, inpatient, and emergency HL7Central systems are 0.035, 0.04, and 0.036 s, respectively. The outpatient, inpatient, and emergency WebUI average response times are 0.79, 1.25, and 0.82 s. The scalability of the rightsizing project and our evaluation results show that the SOA HIS we propose provides evidence that SOA can provide system scalability and sustainability in a highly demanding healthcare information system.

    Inspection systems are used in healthcare to promote quality improvements (i.e. to achieve changes in organisational structures or processes, healthcare provider behaviour and patient outcomes). These systems are based on the assumption that externally promoted adherence to evidence-based standards (through inspection/assessment) will result in higher quality of healthcare. However, the benefits of external inspection in terms of organisational-, provider- and patient-level outcomes are not clear. This is the first update of the original Cochrane review, published in 2011. To evaluate the effectiveness of external inspection of compliance with standards in improving healthcare organisation behaviour, healthcare professional behaviour and patient outcomes. We searched the following electronic databases for studies up to 1 June 2015: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Database of Abstracts of Reviews of Effectiveness, HMIC, ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. There was no language restriction and we included studies regardless of publication status. We also searched the reference lists of included studies and contacted authors of relevant papers, accreditation bodies and the International Organization for Standardization (ISO), regarding any further published or unpublished work. We also searched an online database of systematic reviews (PDQ-evidence.org). We included randomised controlled trials (RCTs), non-randomised trials (NRCTs), interrupted time series (ITSs) and controlled before-after studies (CBAs) evaluating the effect of external inspection against external standards on healthcare organisation change, healthcare professional behaviour or patient outcomes in hospitals, primary healthcare organisations and other community-based healthcare organisations. Two review authors independently applied eligibility criteria, extracted data and assessed the

    Many studies have examined the integration of information systems into healthcare institutions, leading to several standards in the healthcare domain (CORBAmed: Common Object Request Broker Architecture in Medicine; HL7: Health Level Seven International; DICOM: Digital Imaging and Communications in Medicine; and IHE: Integrating the Healthcare Enterprise). Due to the existence of a wide diversity of heterogeneous systems, three essential factors are necessary to fully integrate a system: data, functions and workflow. However, most of the previous studies have dealt with only one or two of these factors and this makes the system integration unsatisfactory. In this paper, we propose a flexible, scalable architecture for Hospital Information Systems (HIS). Our main purpose is to provide a practical solution to insure HIS interoperability so that healthcare institutions can communicate without being obliged to change their local information systems and without altering the tasks of the healthcare professionals. Our architecture is a mediation architecture with 3 levels: 1) a database level, 2) a middleware level and 3) a user interface level. The mediation is based on two central components: the Mediator and the Adapter. Using the XML format allows us to establish a structured, secured exchange of healthcare data. The notion of medical ontology is introduced to solve semantic conflicts and to unify the language used for the exchange. Our mediation architecture provides an effective, promising model that promotes the integration of hospital information systems that are autonomous, heterogeneous, semantically interoperable and platform-independent.

    Healthcare is an increasingly collaborative enterprise involving a broad range of healthcare services provided by many individuals and organizations. Grid technology has been widely recognized as a means for integrating disparate computing resources in the healthcare field. Moreover, Grid portal applications can be developed on a wireless and mobile infrastructure to execute healthcare processes which, in turn, can provide remote access to Grid database services. Such an environment provides ubiquitous and pervasive access to integrated healthcare services at the point of care, thus improving healthcare quality. In such environments, the ability to provide an effective access control mechanism that meets the requirement of the least privilege principle is essential. Adherence to the least privilege principle requires continuous adjustments of user permissions in order to adapt to the current situation. This paper presents a context-aware access control mechanism for HDGPortal, a Grid portal application which provides access to workflow-based healthcare processes using wireless Personal Digital Assistants. The proposed mechanism builds upon and enhances security mechanisms provided by the Grid Security Infrastructure. It provides tight, just-in-time permissions so that authorized users get access to specific objects according to the current context. These permissions are subject to continuous adjustments triggered by the changing context. Thus, the risk of compromising information integrity during task executions is reduced.

    Purpose Strong leadership has been shown to foster change, including loyalty, improved performance and decreased error rates, but there is a dearth of evidence on effectiveness of leadership development programs. To ensure a return on the huge investments made, evidence-based approaches are needed to assess the impact of leadership on health-care establishments. As a part of a pan-Canadian initiative to design an effective evaluative instrument, the purpose of this paper was to identify and summarize evidence on health-care outcomes/return on investment (ROI) indicators and metrics associated with leadership quality, leadership development programs and existing evaluative instruments. Design/methodology/approach The authors performed a scoping review using the Arksey and O'Malley framework, searching eight databases from 2006 through June 2016. Findings Of 11,868 citations screened, the authors included 223 studies reporting on health-care outcomes/ROI indicators and metrics associated with leadership quality (73 studies), leadership development programs (138 studies) and existing evaluative instruments (12 studies). The extracted ROI indicators and metrics have been summarized in detail. Originality/value This review provides a snapshot in time of the current evidence on ROI indicators and metrics associated with leadership. Summarized ROI indicators and metrics can be used to design an effective evaluative instrument to assess the impact of leadership on health-care organizations.

    Effective leadership of healthcare professionals is critical for strengthening quality and integration of care. This study aimed to assess whether there exist an association between different leadership styles and healthcare quality measures. The search was performed in the Medline (National Library of Medicine, PubMed interface) and EMBASE databases for the time period 2004–2015. The research question that guided this review was posed as: “Is there any relationship between leadership style in healthcare settings and quality of care?” Eighteen articles were found relevant to our research question. Leadership styles were found to be strongly correlated with quality care and associated measures. Leadership was considered a core element for a well-coordinated and integrated provision of care, both from the patients and healthcare professionals. PMID:29036901

    This study explores the literature in establishing the value of undergraduate peer-based healthcare ethics teaching as an educational methodology. A narrative review of the literature concerning peer-based ethics teaching was conducted. MEDLINE, EMBASE, CINAHL, SCOPUS databases, and the Cochrane Library, were systematically searched for studies of peer-based ethics or professionalism teaching. Selected studies related peer-based teaching to ethics education outcomes. Ten publications were identified. Selected studies were varied in their chosen intervention methodology and analysis. Collectively, the identified studies suggest peer-based ethics education is an effective and valued educational methodology in training healthcare professionals. One paper suggests peer-based ethics teaching has advantages over traditional didactic methods. Peer-based ethics teaching also receives positive feedback from student participants. However, the limited literature base demonstrates a clear need for more evaluation of this pedagogy. The current literature base suggests that undergraduate peer based healthcare ethics teaching is valuable in terms of efficacy and student satisfaction. We conclude that the medical community should invest in further study in order to capitalise upon the potential of peer-based ethics teaching in undergraduate healthcare education.

    The application of Big Data analytics in healthcare has immense potential for improving the quality of care, reducing waste and error, and reducing the cost of care. This systematic review of literature aims to determine the scope of Big Data analytics in healthcare including its applications and challenges in its adoption in healthcare. It also intends to identify the strategies to overcome the challenges. A systematic search of the articles was carried out on five major scientific databases: ScienceDirect, PubMed, Emerald, IEEE Xplore and Taylor & Francis. The articles on Big Data analytics in healthcare published in English language literature from January 2013 to January 2018 were considered. Descriptive articles and usability studies of Big Data analytics in healthcare and medicine were selected. Two reviewers independently extracted information on definitions of Big Data analytics; sources and applications of Big Data analytics in healthcare; challenges and strategies to overcome the challenges in healthcare. A total of 58 articles were selected as per the inclusion criteria and analyzed. The analyses of these articles found that: (1) researchers lack consensus about the operational definition of Big Data in healthcare; (2) Big Data in healthcare comes from the internal sources within the hospitals or clinics as well external sources including government, laboratories, pharma companies, data aggregators, medical journals etc.; (3) natural language processing (NLP) is most widely used Big Data analytical technique for healthcare and most of the processing tools used for analytics are based on Hadoop; (4) Big Data analytics finds its application for clinical decision support; optimization of clinical operations and reduction of cost of care (5) major challenge in adoption of Big Data analytics is non-availability of evidence of its practical benefits in healthcare.

    Although considered a key driver of racial disparities in healthcare, relatively little is known about the extent of interpersonal racism perpetrated by healthcare providers, nor is there a good understanding of how best to measure such racism. This paper reviews worldwide evidence (from 1995 onwards) for racism among healthcare providers; as well as comparing existing measurement approaches to emerging best practice, it focuses on the assessment of interpersonal racism, rather than internalized or systemic/institutional racism. The following databases and electronic journal collections were searched for articles published between 1995 and 2012: Medline, CINAHL, PsycInfo, Sociological Abstracts. Included studies were published empirical studies of any design measuring and/or reporting on healthcare provider racism in the English language. Data on study design and objectives; method of measurement, constructs measured, type of tool; study population and healthcare setting; country and language of study; and study outcomes were extracted from each study. The 37 studies included in this review were almost solely conducted in the U.S. and with physicians. Statistically significant evidence of racist beliefs, emotions or practices among healthcare providers in relation to minority groups was evident in 26 of these studies. Although a number of measurement approaches were utilized, a limited range of constructs was assessed. Despite burgeoning interest in racism as a contributor to racial disparities in healthcare, we still know little about the extent of healthcare provider racism or how best to measure it. Studies using more sophisticated approaches to assess healthcare provider racism are required to inform interventions aimed at reducing racial disparities in health.

    2014-01-01

    As an alternative to the existing software architectures that underpin the development of smart homes and ambient assisted living (AAL) systems, this work presents a database-centric architecture that takes advantage of active databases and in-database processing. Current platforms supporting AAL systems use database management systems (DBMSs) exclusively for data storage. Active databases employ database triggers to detect and react to events taking place inside or outside of the database. DBMSs can be extended with stored procedures and functions that enable in-database processing. This means that the data processing is integrated and performed within the DBMS. The feasibility and flexibility of the proposed approach were demonstrated with the implementation of three distinct AAL services. The active database was used to detect bed-exits and to discover common room transitions and deviations during the night. In-database machine learning methods were used to model early night behaviors. Consequently, active in-database processing avoids transferring sensitive data outside the database, and this improves performance, security and privacy. Furthermore, centralizing the computation into the DBMS facilitates code reuse, adaptation and maintenance. These are important system properties that take into account the evolving heterogeneity of users, their needs and the devices that are characteristic of smart homes and AAL systems. Therefore, DBMSs can provide capabilities to address requirements for scalability, security, privacy, dependability and personalization in applications of smart environments in healthcare.

    Regional healthcare facility surveys to quantitatively assess nosocomial infection rates are important for confirming standardized data collection and assessing health outcomes in the era of mandatory reporting. This is particularly important for the assessment of infection control policies and healthcare associated infection rates among hospitals. However, the success of such surveys depends upon high participation and representativeness of respondents. This descriptive paper provides methodologies that may have contributed to high participation in a series of administrative, infection control, and microbiology laboratory surveys of all 31 hospitals in a large southern California county. We also report 85% (N = 72) countywide participation in an administrative survey among nursing homes in this same area. Using in-person recruitment, 48% of hospitals and nursing homes were recruited within one quarter, with 75% recruited within three quarters. Potentially useful strategies for successful recruitment included in-person recruitment, partnership with the local public health department, assurance of anonymity when presenting survey results, and provision of staff labor for the completion of detailed survey tables on the rates of healthcare associated pathogens. Data collection assistance was provided for three-fourths of surveys. High compliance quantitative regional surveys require substantial recruitment time and study staff support for high participation.

    Dietary supplement usage in the United States continues to increase. This article explores the background of dietary supplements and their regulations, discusses trends in usage patterns highlighting the properties of 10 popular dietary supplements, addresses safety concerns and drug-nutrient interactions, and discusses the role of the healthcare professional in assessing and recommending usage of dietary supplements. The authors reviewed the literature on dietary supplementation. Government websites were used to obtain background and regulatory information. Evidence-based databases were used to summarize popular dietary supplements in terms of their common uses, mechanisms of action, and clinical implications. The related literature was reviewed to discuss important factors for the healthcare professional to consider as well as the role of the healthcare professional in integrating dietary supplement use within patient care. Healthcare professionals need to be prepared to evaluate dietary supplement usage and make appropriate recommendations for an individualized plan of care. As the popularity of dietary supplements continues to grow, healthcare professionals will need to communicate with patients about their usage; educate themselves on their potential benefits, interactions, and contraindications; evaluate the literature; make recommendations; and document appropriately in a comprehensive and integrated plan of care.

    A web-based system can provide access to real-time data and information. Healthcare is moving towards digitizing patients' medical information and securely exchanging it through web-based systems. In one of Ontario's health regions, Nurse Led Outreach Teams (NLOT) provide emergency mobile nursing services to help reduce unnecessary transfers from long-term care homes to emergency departments. Currently the NLOT team uses a Microsoft Access database to keep track of the health information on the residents that they serve. The Access database lacks scalability, portability, and interoperability. The objective of this study is the development of a web-based database using Oracle Application Express that is easily accessible from mobile devices. The web-based database will allow NLOT nurses to enter and access resident information anytime and from anywhere.

    This literature review examines the current trend in nurses' attitudes toward healthcare information technology (HIT). HIT implementation and expansion are at the core of global efforts to improve healthcare quality and patient safety. As a large portion of the healthcare workforce, nurses' attitudes towards HIT are likely to have a major impact on the electronic health record (EHR) implementation process. A search of PubMed, CINAHL and Medline databases produced 1930 combined hits. Returned articles were scanned for relevancy and applicability. Thirteen articles met all criteria and were subsequently reviewed in their entirety. In accordance with two change theories, if HIT implementation projects are to be successful, nurses must recognize that incorporating EHRs into their daily practice is beneficial to patient outcomes. Overall, the attitudes of nurses toward HIT are positive. Increased computer experience is the main demographic indicator for positive attitudes. The most common detractors are poor system design, system slowdown and system downtime. Nurses are also fearful that the use of technology will dehumanize patient care. Involving nurses in system design is likely to improve post-implementation satisfaction. Creating a positive, supportive atmosphere appears to be instrumental to sustainability.

    Electronic health record (EHR) projects have been launched in most developed countries to increase the quality of healthcare while decreasing its cost. The benefits provided by centralizing the healthcare information in database systems are unquestionable in terms of information quality, availability, and protection against failure. Yet, patients are reluctant to give to a distant server the control over highly sensitive data (e.g., data revealing a severe or shameful disease). This paper capitalizes on a new hardware portable device, associating the security of a smart card to the storage capacity of a USB key, to give back to the patient the control over his medical data. This paper shows how this device can complement a traditional EHR server to (1) protect and share highly sensitive data among trusted parties and (2) provide a seamless access to the data even in disconnected mode. The proposed architecture is experimented in the context of a medicosocial network providing medical care and social services at home for elderly people. PMID:18615200

    2015-04-01

    Electronic storage of healthcare data, including individual-level risk factors for both infectious and other diseases, is increasing. These data can be integrated at hospital, regional and national levels. Data sources that contain risk factor and outcome information for a wide range of conditions offer the potential for efficient epidemiological analysis of multiple diseases. Opportunities may also arise for monitoring healthcare processes. Integrating diverse data sources presents epidemiological, practical, and ethical challenges. For example, diagnostic criteria, outcome definitions, and ascertainment methods may differ across the data sources. Data volumes may be very large, requiring sophisticated computing technology. Given the large populations involved, perhaps the most challenging aspect is how informed consent can be obtained for the development of integrated databases, particularly when it is not easy to demonstrate their potential. In this article, we discuss some of the ups and downs of recent projects as well as the potential of data warehousing for antimicrobial resistance monitoring. Copyright © 2015.

    It is extremely important for the healthcare domain to have a standardized communication because will improve the quality of information and in the end the resulting benefits will improve the quality of patients' life. The standards proposed to be used are: HL7 CDA and CCD. For a better access to the medical data a solution based on cloud computing (CC) is investigated. CC is a technology that supports flexibility, seamless care, and reduced costs of the medical act. To ensure interoperability between healthcare information systems a solution creating a Web Custom Control is presented. The control shows the database tables and fields used to configure the two standards. This control will facilitate the work of the medical staff and hospital administrators, because they can configure the local system easily and prepare it for communication with other systems. The resulted information will have a higher quality and will provide knowledge that will support better patient management and diagnosis.

  14. Healthcare plans and consumer perceptions of healthcare institutions.

    This study evaluates the effect of healthcare insurance plans on consumer perception of trust in a healthcare institution, and the mediating effect of trust on consumer loyalty towards an institution. The study was conducted at a healthcare institution in Colombia where a total of 841 patients responded to a questionnaire. A structural equation model shows that individuals who have a pre-paid healthcare plan have a stronger evaluation of trust compared to those who hold a regulated healthcare plan (i.e., subsidized and contributory plans). In turn, trust positively predicts consumers' loyalty towards an institution. The relationship between the patients' healthcare plans and their degree of loyalty towards healthcare institutions is completely mediated by their perception of trust towards the institution. A greater perception of trust is explained by having a medical plan that provides consumers with more flexibility, allowing them to select their health provider at a premium price. Although health institutions do not control healthcare regimes, these affect consumers' trust in their service. Institutions cannot modify characteristics of the regime, but they can promote a trustworthy environment to strengthen consumers' loyalty to the institution.

    The proportion of people living with HIV/AIDS in the ageing population (>50 years old) is increasing. We aimed to explore the relationship between older age and treatment outcomes in HIV-positive persons from the Asia Pacific region. Patients from the Australian HIV Observational Database (AHOD) and the TREAT Asia HIV Observational Database (TAHOD) were included in the analysis. We used survival methods to assess the association between older age and all-cause mortality, as well as time to treatment modification. We used regression analyses to evaluate changes in CD4 counts after combination antiretroviral therapy (cART) initiation and determined the odds of detectable viral load, up to 24 months of treatment. A total of 7142 patients were included in these analyses (60% in TAHOD and 40% in AHOD), of whom 25% were >50 years old. In multivariable analyses, those aged > 50 years were at least twice as likely to die as those aged 30-39 years [hazard ratio (HR) for 50-59 years: 2.27; 95% confidence interval (CI) 1.34-3.83; HR for > 60 years: 4.28; 95% CI 2.42-7.55]. The effect of older age on CD4 count changes was insignificant (p-trend=0.06). The odds of detectable viral load after cART initiation decreased with age (p-trend=< 0.0001). The effect of older age on time to first treatment modification was insignificant (p-trend=0.21). We found no statistically significant differences in outcomes between AHOD and TAHOD participants for all endpoints examined. The associations between older age and typical patient outcomes in HIV-positive patients from the Asia Pacific region are similar in AHOD and TAHOD. Our data indicate that 'age effects' traverse the resource-rich and resource-limited divide and that future ageing-related findings might be applicable to each setting. © 2014 British HIV Association.

    Objectives One of the main objectives of the Targeted Subsidies Law (TSL) in Iran was to improve equity in healthcare financing. This study aimed at measuring the effects of the TSL, which was implemented in Iran in 2010, on equity in healthcare financing. Methods Segmented regression analysis was applied to assess the effects of TSL implementation on the Gini and Kakwani indices of outcome variables in Iranian households. Data for the years 1977-2014 were retrieved from formal databases. Changes in the levels and trends of the outcome variables before and after TSL implementation were assessed using Stata version 13. Results In the 33 years before the implementation of the TSL, the Gini index decreased from 0.401 to 0.381. The Gini index and its intercept significantly decreased to 0.362 (p<0.001) 5 years after the implementation of the TSL. There was no statistically significant change in the gross domestic product or inflation rate after TSL implementation. The Kakwani index significantly increased from -0.020 to 0.007 (p<0.001) before the implementation of the TSL, while we observed no statistically significant change (p=0.81) in the Kakwani index after TSL implementation. Conclusions The TSL reform, which was introduced as part of an economic development plan in Iran in 2010, led to a significant reduction in households’ income inequality. However, the TSL did not significantly affect equity in healthcare financing. Hence, while measuring the long-term impact of TSL is paramount, healthcare decision-makers need to consider the efficacy of the TSL in order to develop plans for achieving the desired equity in healthcare financing.

    Quality improvement, value-based care delivery, and personalized patient care depend on robust clinical, financial, and demographic data streams of neurosurgical outcomes. The neurosurgical literature lacks a comprehensive review of large national databases. To assess the strengths and limitations of various resources for outcomes research in neurosurgery. A review of the literature was conducted to identify surgical outcomes studies using national data sets. The databases were assessed for the availability of patient demographics and clinical variables, longitudinal follow-up of patients, strengths, and limitations. The number of unique patients contained within each data set ranged from thousands (Quality Outcomes Database [QOD]) to hundreds of millions (MarketScan). Databases with both clinical and financial data included PearlDiver, Premier Healthcare Database, Vizient Clinical Data Base and Resource Manager, and the National Inpatient Sample. Outcomes collected by databases included patient-reported outcomes (QOD); 30-day morbidity, readmissions, and reoperations (National Surgical Quality Improvement Program); and disease incidence and disease-specific survival (Surveillance, Epidemiology, and End Results-Medicare). The strengths of large databases included large numbers of rare pathologies and multi-institutional nationally representative sampling; the limitations of these databases included variable data veracity, variable data completeness, and missing disease-specific variables. The improvement of existing large national databases and the establishment of new registries will be crucial to the future of neurosurgical outcomes research.

    Healthcare information professionals play a key role in closing the knowledge gap between medical research and clinical practice. Their work involves meticulous searching of literature databases using complex search strategies that can consist of hundreds of keywords, operators, and ontology terms. This process is prone to error and can lead to inefficiency and bias if performed incorrectly. The aim of this study was to investigate the search behavior of healthcare information professionals, uncovering their needs, goals, and requirements for information retrieval systems. A survey was distributed to healthcare information professionals via professional association email discussion lists. It investigated the search tasks they undertake, their techniques for search strategy formulation, their approaches to evaluating search results, and their preferred functionality for searching library-style databases. The popular literature search system PubMed was then evaluated to determine the extent to which their needs were met. The 107 respondents indicated that their information retrieval process relied on the use of complex, repeatable, and transparent search strategies. On average it took 60 minutes to formulate a search strategy, with a search task taking 4 hours and consisting of 15 strategy lines. Respondents reviewed a median of 175 results per search task, far more than they would ideally like (100). The most desired features of a search system were merging search queries and combining search results. Healthcare information professionals routinely address some of the most challenging information retrieval problems of any profession. However, their needs are not fully supported by current literature search systems and there is demand for improved functionality, in particular regarding the development and management of search strategies. ©Tony Russell-Rose, Jon Chamberlain.

    Lack of resources is one of the main problems of all healthcare systems. Recent studies have shown that reducing the overuse of medical services plays an important role in reducing healthcare system costs. Overuse of medical services is a major problem in the healthcare system, and it threatens the quality of the services, can harm patients and create excess costs for patients. So far, few studies have been conducted in this regard in Iran. The main objective of this systematic review is to perform an inclusive search for studies that report overuse of medical services in the Iranian healthcare system. An extensive search of the literature will be conducted in six databases including PubMed, Embase, Scopus, Web of Science, Cochrane and Scientific Information Database using a comprehensive search strategy to identify studies on overuse of medical care. The search will be done without time limit until the end of 2017, completed by reference tracking, author tracking and expert consultation. The search will be conducted on 1 February 2018. Any study that reports an overuse in a service based on a specific standard will be included in the study. Two reviewers will screen the articles based on the title, abstract and full text, and extract data about type of service, clinical area and overuse rate. Quality appraisal will be assessed using the Joanna Briggs Institute checklist. Potential discrepancies will be resolved by consulting a third author. Recommendations will be made to the Iranian MOHME (Ministry of Health and Medical Education) in order to make better evidence-based decisions about medical services in the future.

    This paper explains the procedures involved in creating a database of scientific papers that use observational data and linking the records to the observations residing in a data archive. Based on our experiences with the ESO Telescope Bibliography, we describe the workflow we apply in order to retrieve relevant articles, assign tags to describe the observing facilities that generated the data, and identify the correct program identification numbers (IDs). These program identifiers are particularly important as they link the published papers and the underlying data and enable scientists to access the data for new studies. With the understanding that the difficulty of compiling correct and complete data varies, depending on the information readily provided in the published literature, this paper proposes an evolution of search options for finding appropriate ID numbers. To explore the process and its various stages, we use the analogy of the "cookbook." These search methodologies might be labeled fast, medium, and slow heat recipes within our culinary theme. We provide a step-by-step guide in order to assist other bibliography compilers, in particular those who are new to the field.

    Introduction Interactions between pharmaceutical companies and healthcare providers are increasingly scrutinized by academics, professionals, media, and politicians. Most empirical studies and professional guidelines focus on unilateral donor-recipient types of interaction and overlook, or fail to distinguish between, more reciprocal types of interaction. However, the degree of goal alignment and potential for value creation differs in these two types of interactions. Failing to differentiate between these two forms of interaction between pharmaceutical companies and healthcare providers could thus lead to biased conclusions regarding their desirability. This study reviews the empirical literature regarding the effects of bilateral forms of interactions between pharmaceutical companies and healthcare providers in order to explore their effects. Material and methods We searched two medical databases (i.e. PubMed and Cochrane Library) and one business database (i.e. EBSCO) for empirical, peer-reviewed articles concerning any type of bilateral interaction between pharmaceutical companies and healthcare providers. We included quantitative articles which were written in English and published between January 1st, 2000 and October 31st, 2016, and where the title or abstract included a combination of synonyms of the following keywords: pharmaceutical companies, healthcare providers, interaction, and effects. Results Our search results yielded 10 studies which were included in our analysis. These studies focused on either research-oriented interaction or on education-oriented interaction. The included studies reported various outcomes of interaction such as prescribing behavior, ethical dilemmas, and research output. Regardless of the type of interaction, the studies either reported no significant effects or ambivalent outcomes such as affected clinical practice or ethical issues. Discussion and conclusion The effects of bilateral interactions reported in the literature are

    Approximately 20% of healthcare workers in high-income countries such as Australia, Canada and the USA work in rural areas. Healthcare workers are known to be vulnerable to occupational injury and poor work disability outcomes; given their rural-urban distribution, it is possible to compare work disability prevention in rural and urban areas. However, little attention has been paid to work disability prevention issues specific to rural workers, including rural healthcare workers. A comprehensive review of the literature was conducted to identify rural-urban differences in work disability outcomes (defined as the incidence of occupational injury and the duration of associated work absence), as well as risk factors for poor work disability outcomes in rural healthcare workers. The databases MEDLINE, CINAHL, and EMBASE were searched, as were relevant research centers and government agencies, to identify all quantitative and qualitative English-language studies published between 1 January 2000 and 6 October 2009 that discussed occupational injury, work absence duration, work disability management, or risk factors for poor work disability outcomes, for rural workers specifically, or in comparison with urban workers. To ensure inclusion of studies of healthcare workers as a distinct group among other sector-specific groups, a broad search for literature related to all industrial sectors was conducted. Of 860 references identified, 5 discussed work disability outcomes and 25 discussed known risk factors. Known risk factors were defined as factors firmly established to be associated with poor work disability outcomes in the general worker population based on systematic reviews, well-established conceptual models of work disability prevention, and public health literature. Although somewhat conflicting, the evidence suggests that rural healthcare workers experience higher rates of occupational injury compared with urban healthcare workers, within occupational categories

    Childhood obesity is a global public health challenge. Parental feeding practices, such as responsive feeding, are implicated in the etiology of childhood obesity. This systematic review aimed to examine of effects of healthcare professional-delivered early feeding interventions, on parental feeding practices, dietary intake, and weight outcomes for children up to 2 years. The role of responsive feeding interventions was also specifically examined. Databases searched included: CINAHL, the Cochrane Library, EMBASE, Medline, PubMed, PsycINFO, and Maternity and Infant Care. participants are parents of children ≤2 years; intervention includes focus on early child feeding to prevent overweight and obesity; intervention delivered by healthcare professionals. Sixteen papers, representing 10 trials, met inclusion criteria for review. Six interventions included responsive feeding components. Interventions demonstrated inconsistent effects on feeding practices, dietary intake, and weight outcomes. Findings suggest some reductions in pressure to eat and infant consumption of non-core beverages. Responsive feeding based interventions demonstrate greater improvements in feeding approaches, and weight outcomes. The findings of this review highlight the importance of incorporating responsive feeding in healthcare professional delivered early feeding interventions to prevent childhood obesity. Observed inconsistencies across trials may be explained by methodological limitations. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Magnitude and frequency of HIV viral load blips in resource-limited settings, has not previously been assessed. This study was undertaken in a cohort from a high income country (Australia) known as AHOD (Australian HIV Observational Database) and another cohort from a mixture of Asian countries of varying national income per capita, TAHOD (TREAT Asia HIV Observational Database). Blips were defined as detectable VL (≥ 50 copies/mL) preceded and followed by undetectable VL (<50 copies/mL). Virological failure (VF) was defined as two consecutive VL ≥50 copies/ml. Cox proportional hazard models of time to first VF after entry, were developed. 5040 patients (AHOD n = 2597 and TAHOD n = 2521) were included; 910 (18%) of patients experienced blips. 744 (21%) and 166 (11%) of high- and middle/low-income participants, respectively, experienced blips ever. 711 (14%) experienced blips prior to virological failure. 559 (16%) and 152 (10%) of high- and middle/low-income participants, respectively, experienced blips prior to virological failure. VL testing occurred at a median frequency of 175 and 91 days in middle/low- and high-income sites, respectively. Longer time to VF occurred in middle/low income sites, compared with high-income sites (adjusted hazards ratio (AHR) 0.41; p<0.001), adjusted for year of first cART, Hepatitis C co-infection, cART regimen, and prior blips. Prior blips were not a significant predictor of VF in univariate analysis (AHR 0.97, p = 0.82). Differing magnitudes of blips were not significant in univariate analyses as predictors of virological failure (p = 0.360 for blip 50-≤1000, p = 0.309 for blip 50-≤400 and p = 0.300 for blip 50-≤200). 209 of 866 (24%) patients were switched to an alternate regimen in the setting of a blip. Despite a lower proportion of blips occurring in low/middle-income settings, no significant difference was found between settings. Nonetheless, a substantial number of participants were switched

    Electronic medical records (EMRs) are posited as a tool for improving practice, policy and research in primary healthcare. This paper describes the Deliver Primary Healthcare Information (DELPHI) Project at the Department of Family Medicine at the University of Western Ontario, focusing on its development, current status and research potential in order to share experiences with researchers in similar contexts. The project progressed through four stages: (a) participant recruitment, (b) EMR software modification and implementation, (c) database creation and (d) data quality assessment. Currently, the DELPHI database holds more than two years of high-quality, de-identified data from 10 practices, with 30,000 patients and nearly a quarter of a million encounters.

    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

    Tele-rehabilitation at home is one of the promising approaches in increasing rehabilitative success and simultaneously decreasing the financial burden on the healthcare system. Novel and mostly mobile devices are already in use, but shall be used in the future to a higher extent for allowing at home rehabilitation processes at a high quality level. The combination of exercises, assessments and available equipment is the basic objective of the presented database. The database has been structured in order to allow easy-to-use and fast access for the three main user groups. Therapists - looking for exercise and equipment combinations - patients - rechecking their tasks for home exercises - and manufacturers - entering their equipment for specific use cases. The database has been evaluated by a proof of concept study and shows a high degree of applicability for the field of rehabilitative medicine. Currently it contains 110 exercises/assessments and 111 equipment/systems. Foundations of presented database are already established in the rehabilitative field of application, but can and will be enhanced in its functionality to be usable for a higher variety of medical fields and specifications.

    Historically, an important part of the scientific research cycle is to situate any research project within the landscape of the existing scientific literature. In the field of discipline-based astronomy education research, grappling with the existing literature base has proven difficult because of the difficulty in obtaining research reports from around the world, particularly early ones. In order to better survey and efficiently utilize the wide and fractured range and domain of astronomy education research methods and results, the iSTAR international Study of Astronomical Reasoning database project was initiated. The project aims to host a living, online repository of dissertations, theses, journal articles, and grey literature resources to serve the world's discipline-based astronomy education research community. The first domain of research artifacts ingested into the iSTAR database were doctoral dissertations. To the authors' great surprise, nearly 300 astronomy education research dissertations were found from the last 100-years. Few, if any, of the literature reviews from recent astronomy education dissertations surveyed even come close to summarizing this many dissertations, most of which have not been published in traditional journals, as re-publishing one's dissertation research as a journal article was not a widespread custom in the education research community until recently. A survey of the iSTAR database dissertations reveals that the vast majority of work has been largely quantitative in nature until the last decade. We also observe that modern-era astronomy education research writings reaches as far back as 1923 and that the majority of dissertations come from the same eight institutions. Moreover, most of the astronomy education research work has been done covering learners' grasp of broad knowledge of astronomy rather than delving into specific learning targets, which has been more in vogue during the last two decades.

    Applications of genomic studies are spreading rapidly in many domains of science and technology such as healthcare, biomedical research, direct-to-consumer services, and legal and forensic. However, there are a number of obstacles that make it hard to access and process a big genomic database for these applications. First, sequencing genomic sequence is a time consuming and expensive process. Second, it requires large-scale computation and storage systems to process genomic sequences. Third, genomic databases are often owned by different organizations, and thus, not available for public usage. Cloud computing paradigm can be leveraged to facilitate the creation and sharing of big genomic databases for these applications. Genomic data owners can outsource their databases in a centralized cloud server to ease the access of their databases. However, data owners are reluctant to adopt this model, as it requires outsourcing the data to an untrusted cloud service provider that may cause data breaches. In this paper, we propose a privacy-preserving model for outsourcing genomic data to a cloud. The proposed model enables query processing while providing privacy protection of genomic databases. Privacy of the individuals is guaranteed by permuting and adding fake genomic records in the database. These techniques allow cloud to evaluate count and top-k queries securely and efficiently. Experimental results demonstrate that a count and a top-k query over 40 Single Nucleotide Polymorphisms (SNPs) in a database of 20 000 records takes around 100 and 150 s, respectively.

    While previous research establishes an association between social relations, health and use of healthcare services among older people, how to implement this knowledge in real-life settings has received much less attention. This study will explore the relationship between social relations, health and use of healthcare services in a Danish mid-life population sample. In addition, the study will explore individual and contextual factors affecting the implementation of a group-based life story intervention aimed at establishing and strengthening social relations among older people at nursing homes in Denmark. A combined quantitative register-based approach and a qualitative implementation approach will be applied in this study. First, we will quantitatively analyse the relationship between social relations, health status and use of healthcare services among middle-aged people in Denmark by linking survey data on social relations, loneliness, self-perceived health and disease status from the Copenhagen Aging and Midlife Biobank (CAMB) (n = 7191) with national registries through the Public Health Database on use of healthcare services and demographic and socioeconomic factors. Second, we will qualitatively analyse individual and contextual factors affecting the implementation process of the group-based life story intervention based on semi-structured interviews (n = 16), observations and field notes with and among intervention stakeholders, i.e., participants and group leaders facilitating the intervention. The results of this study are expected to improve knowledge about mechanisms through which social relations are associated with health status and use of healthcare services and to inform the implementation of future interventions targeting social relations among older people at nursing homes. The study has been registered and approved by the Danish Data Protection Agency. Seperate approvals have been attained for the qualitative data (Approval No. SUND-2016

    To characterize healthcare costs, resource use, and treatment patterns of survey respondents with a history of depression who are high utilizers (HUds) of healthcare and to identify factors associated with high utilization. Adults with two or more depression diagnoses identified from the HealthCore Integrated Research Database were invited to participate in the CODE study, which links survey data with 12-month retrospective claims data. Patient surveys provided data on demographics, general health, and symptoms and/or comorbidities associated with depression. Similar clinical conditions also were identified from the medical claims. Factors associated with high utilization were identified using logistic regression models. Of 3132 survey respondents, 1921 were included, 193 of whom were HUds (defined as those who incurred the top 10% of total all-cause costs in the preceding 12months). Mean total annual healthcare costs were eightfold greater for HUds than for non-HUds ($US56,145 vs. $US6,954; p<.0001). HUds incurred more inpatient encounters (p<.0001) and emergency department (p=.01) and physician office visits (p<.0001). Similar findings were observed for mental healthcare costs/resource use. HUds were prescribed twice as many medications (total mean: 16.86 vs. 8.32; psychotropic mean: 4.11 vs. 2.61; both p<.0001). HUds reported higher levels of depression severity, fatigue, sleep difficulties, pain, high alcohol consumption, and anxiety. Predictors of becoming a HUd included substance use, obesity, cardiovascular disease, comorbidity severity, psychiatric conditions other than depression, and pain. Focusing on pain, substance use, and psychiatric conditions beyond depression may be effective approaches to reducing high costs in patients with depression. Copyright © 2016 Eli Lilly and Company.

    Unresolved conflicts among healthcare professionals can lead to difficult patient care consequences. This scoping review examines the current healthcare literature that reported sources and consequences of conflict associated with individual, interpersonal, and organisational factors. We identified 99 articles published between 2001 and 2015 from PubMed, Cumulative Index to Nursing and Allied Health Literature, and Excerpta Medical Database. Most reviewed studies relied on healthcare professionals' perceptions and beliefs associated with conflict sources and consequences, with few studies reporting behavioural or organisational change outcomes. Individual conflict sources included personal traits, such as self-focus, self-esteem, or worldview, as well as individuals' conflict management styles. These conflicts posed threats to one's physical, mental, and emotional health and to one's ability to perform at work. Interpersonal dynamics were hampered by colleagues' uncivil behaviours, such as low degree of support, to more destructive behaviours including bullying or humiliation. Perceptions of disrespectful working environment and weakened team collaboration were the main interpersonal conflict consequences. Organisational conflict sources included ambiguity in professional roles, scope of practice, reporting structure, or workflows, negatively affecting healthcare professionals' job satisfactions and intent to stay. Future inquiries into healthcare conflict research may target the following: shifting from research involving single professions to multiple professions; dissemination of studies via journals that promote interprofessional research; inquiries into the roles of unconscious or implicit bias, or psychological capital (i.e., resilience) in healthcare conflict; and diversification of data sources to include hospital or clinic data with implications for conflict sources.

    Healthcare delivery in America is extremely complex because it is comprised of a fragmented and nonsystematic mix of stakeholders, components, and processes. Within the US healthcare structure, the federal healthcare system is poised to lead American medicine in leveraging health information technology to improve the quality of healthcare. We posit that through developing, adopting, and refining health information technology, the federal healthcare system has the potential to transform federal healthcare quality by managing the complexities associated with healthcare delivery. Although federal mandates have spurred the widespread use of electronic health records, other beneficial technologies have yet to be adopted in federal healthcare settings. The use of health information technology is fundamental in providing the highest quality, safest healthcare possible. In addition, health information technology is valuable in achieving the Agency for Healthcare Research and Quality's implementation goals. We conducted a comprehensive literature search using the Google Scholar, PubMed, and Cochrane databases to identify an initial list of articles. Through a thorough review of the titles and abstracts, we identified 42 articles as having relevance to health information technology and quality. Through our exclusion criteria of currency of the article, citation frequency, applicability to the federal health system, and quality of research supporting conclusions, we refined the list to 11 references from which we performed our analysis. The literature shows that the use of computerized physician order entry has significantly increased accurate medication dosage and decreased medication errors. The use of clinical decision support systems have significantly increased physician adherence to guidelines, although there is little evidence that indicates any significant correlation to patient outcomes. Research shows that interoperability and usability are continuing challenges for

    The quality of spectroscopic parameters that serve as input to forward radiative transfer models are essential to fully exploit remote sensing of Earth atmosphere. However, the process of updating spectroscopic databases in order to provide the users with a database that insures an optimal characterization of spectral properties of molecular absorption for radiative transfer modeling is challenging. The evaluation of the databases content and the underlying choices made by the managing team is thus a crucial step. Here, we introduce an original and powerful approach for evaluating spectroscopic parameters: the Spectroscopic Parameters And Radiative Transfer Evaluation (SPARTE) chain. The SPARTE chain relies on the comparison between forward radiative transfer simulations made by the 4A radiative transfer model and observations of spectra made from various observations collocated over several thousands of well-characterized atmospheric situations. Averaging the resulting 'calculated-observed spectral' residuals minimizes the random errors coming from both the radiometric noise of the instruments and the imperfect description of the atmospheric state. The SPARTE chain can be used to evaluate any spectroscopic databases, from the visible to the microwave, using any type of remote sensing observations (ground-based, airborne or space-borne). We show that the comparison of the shape of the residuals enables: (i) identifying incorrect line parameters (line position, intensity, width, pressure shift, etc.), even for molecules for which interferences between the lines have to be taken into account; (ii) proposing revised values, in cooperation with contributing teams; and (iii) validating the final updated parameters. In particular, we show that the simultaneous availability of two databases such as GEISA and HITRAN helps identifying remaining issues in each database. The SPARTE chain has been here applied to the validation of the update of GEISA-2015 in 2 spectral regions

    Purpose The purpose of this paper is to describe and analyze conditions that influence how employees engage in healthcare quality improvement (QI) work. Design/methodology/approach Qualitative case study based on interviews ( n=27) and observations ( n=10). Findings The main conditions that influence how employees engage in healthcare QI work are professions, work structures and working relationships. These conditions can both prevent and facilitate healthcare QI. Professions and work structures may cement existing institutional logics and thus prevent employees from engaging in healthcare QI work. However, attempts to align QI with professional logics, together with work structures that empower employees, can make these conditions increase employee engagement, which can be accomplished through positive working relationships that foster institutional work, which bridge different competing institutional logics, making it possible to overcome barriers that professions and work structures may constitute. Practical implications Understanding the conditions that influence how employees engage in healthcare QI work will make initiatives more likely to succeed. Originality/value Healthcare QI has mainly been studied from an implementer perspective, and employees have either been neglected or seen as passive resisters. Weak employee perspectives make healthcare QI research incomplete. In our research, healthcare QI work is studied closely at the actor level to understand healthcare QI from an employee perspective.

    Background: The Institute of Medicine framework defines six dimensions of quality for healthcare systems: (1) safety, (2) effectiveness, (3) patient centeredness, (4) timeliness of care, (5) efficiency, and (6) equity. Large health datasets provide an opportunity to assess quality in these areas. Objective: To perform an international comparison of the measurability of the delivery of these aims, in people with type 2 diabetes mellitus (T2DM) from large datasets. Method: We conducted a survey to assess healthcare outcomes data quality of existing databases and disseminated this through professional networks. We examined the data sources used to collect the data, frequency of data uploads, and data types used for identifying people with T2DM. We compared data completeness across the six areas of healthcare quality, using selected measures pertinent to T2DM management. Results: We received 14 responses from seven countries (Australia, Canada, Italy, the Netherlands, Norway, Portugal, Turkey and the UK). Most databases reported frequent data uploads and would be capable of near real time analysis of healthcare quality.The majority of recorded data related to safety (particularly medication adverse events) and treatment efficacy (glycaemic control and microvascular disease). Data potentially measuring equity was less well recorded. Recording levels were lowest for patient-centred care, timeliness of care, and system efficiency, with the majority of databases containing no data in these areas. Databases using primary care sources had higher data quality across all areas measured. Conclusion: Data quality could be improved particularly in the areas of patient-centred care, timeliness, and efficiency. Primary care derived datasets may be most suited to healthcare quality assessment. Georg Thieme Verlag KG Stuttgart.

    To investigate the association between nonadherence to diabetes treatment and the occurrence of diabetes complications. Our study retrospectively identified adherence and nonadherence to diabetes treatment in patients during the first year of observation after new diagnoses of type 2 diabetes enrolled in commercial database from 52 health insurers in Japan. Participants were insurance enrollees with type 2 diabetes who received healthcare between 2005 and 2013, and who could be tracked for more than 12months from the initiation of diabetes treatment. We compared the occurrence of diabetes-related complications (retinopathy, nephropathy, neuropathy, ischemic heart disease, cerebrovascular disease, and chronic arterial occlusion) and all-cause healthcare expenditure during the second to eighth years. We identified 1784 nonadherent patients and 9547 adherent patients. Cox proportional hazard models showed that the occurrence of microvascular complications was significantly higher in the nonadherent group: the hazard ratios (95% confidence intervals) for retinopathy, nephropathy, and neuropathy were 2.04 (1.57-2.66), 1.91 (1.35-2.72), and 1.83 (1.02-3.27), respectively. However, no significant differences were observed between the adherent and nonadherent groups for the macrovascular complications (ischemic heart disease, cerebrovascular disease, and chronic arterial occlusion). In addition, the nonadherent group had a significantly higher cumulative healthcare expenditure than the adherent group during the second-to-fifth-year period (p=0.029) and the second-to-sixth-year period (p=0.009) after treatment initiation. Nonadherence in the first year of diabetes may increase the incidence of complications and result in higher expenditures for patients and payers. Copyright © 2016 Elsevier Ireland Ltd.

    The aging of the population creates pressure on the healthcare systems in various ways. A massive increase of chronic disease conditions and age-related illness are predicted as the dominant forces driving the future health care. The objective of this paper is to present future research demands in pervasive healthcare with the goal to meet the healthcare challenges by paving the way for a pervasive, user-centered and preventive healthcare model. This paper presents recent methodological approaches and proposes future research topics in three areas: i) pervasive, continuous and reliable long-term monitoring systems; ii) prevention through pervasive technology as a key element to maintain lifelong wellness; and iii) design and evaluation methods for ubiquitous, patient-centric technologies. Pervasive technology has been identified as a strong asset for achieving the vision of user-centered preventive healthcare. In order to make this vision a reality, new strategies for design, development and evaluation of technology have to find a common denominator and consequently interoperate. Moreover, the potential of pervasive healthcare technologies offers new opportunities beyond traditional disease treatment and may play a major role in prevention, e.g. motivate healthy behavior and disease prevention throughout all stages of life. In this sense, open challenges in future research have to be addressed such as the variability of health indicators between individuals and the manner in which relevant health indicators are provided to the users in order to maximize their motivation to mitigate or prevent unhealthy behaviors. Additionally, collecting evidence that pervasive technology improves health is seen as one of the toughest challenges. Promising approaches are recently introduced, such as "clinical proof-of-concept" and balanced observational studies. The paper concludes that pervasive healthcare will enable a paradigm shift from the established centralized healthcare

    Healthcare waste management continues to present an array of challenges for developing countries, and Botswana is no exception. The possible impact of healthcare waste on public health and the environment has received a lot of attention such that Waste Management dedicated a special issue to the management of healthcare waste (Healthcare Wastes Management, 2005. Waste Management 25(6) 567-665). As the demand for more healthcare facilities increases, there is also an increase on waste generation from these facilities. This situation requires an organised system of healthcare waste management to curb public health risks as well as occupational hazards among healthcare workers as a result of poor waste management. This paper reviews current waste management practices at the healthcare facility level and proposes possible options for improvement in Botswana.

    Economic evaluations are increasingly utilized to inform decisions in healthcare; however, decisions remain uncertain when they are not based on adequate evidence. Value of information (VOI) analysis has been proposed as a systematic approach to measure decision uncertainty and assess whether there is sufficient evidence to support new technologies. The objective of this paper is to review the principles and applications of VOI analysis in healthcare. Relevant databases were systematically searched to identify VOI articles. The findings from the selected articles were summarized and narratively presented. Various VOI methods have been developed and applied to inform decision-making, optimally designing research studies and setting research priorities. However, the application of this approach in healthcare remains limited due to technical and policy challenges. There is a need to create more awareness about VOI analysis, simplify its current methods, and align them with the needs of decision-making organizations.

    To examine racial differences in healthcare utilization and costs for persons with aphasia (PWA) being treated in acute care hospitals in North Carolina (NC). NC Healthcare Cost and Utilization Project State Inpatient Database (HCUP-SID) data from 2011-2012 were analyzed to examine healthcare utilization and costs of care for stroke patients with aphasia. Analyses emphasized length of stay, charges and cost of general hospital services. Generalized linear models (GLM) were constructed to determine the impact of demographic characteristics, stroke/illness severity, and observed hospital characteristics on utilization and costs. Hospital fixed effects were included to yield within-hospital estimates of disparities. GLM models demonstrated that Blacks with aphasia experienced 1.9days longer lengths of stay compared to Whites with aphasia after controlling for demographic characteristics, 1.4days controlling for stroke/illness severity, 1.2days controlling for observed hospital characteristics, and ~1 extra day controlling for unobserved hospital characteristics. Similarly, Blacks accrued ~$2047 greater total costs compared to Whites after controlling for demographic characteristics, $1659 controlling for stroke/illness severity, $1338 controlling for observed hospital characteristics, and ~$1311 greater total costs after controlling for unobserved hospital characteristics. In the acute hospital setting, Blacks with aphasia utilize greater hospital services during longer hospitalizations and at substantially higher costs in the state of NC. A substantial portion of the adjusted difference was related to the hospital treating the patient. However, even after controlling for the hospital, the differences remained clinically and statistically significant. Copyright © 2017 Elsevier B.V. All rights reserved.

    Healthcare supply expenses consume a large part of the financial resources allocated to public health. The aim of this study was to analyze the use of a benchmarking process in the management of hospital purchases, as well as its effect on product cost reduction and quality improvement. Data were collected through a survey conducted in 29 primary healthcare districts from 2010 to 2011, and through a healthcare database on the prices, quality, delivery time and supplier characteristics of 5373 products. The use of benchmarking processes reduced or eliminated products with a low quality and high price. These processes increased the quality of products by 10.57% and reduced their purchase price by 28.97%. The use of benchmarking by healthcare centers can reduce expenditure and allow more efficient management of the healthcare supply chain. It also facilitated the acquisition of products at lower prices and higher quality. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

    To describe the management and costs associated with G-CSF therapy in cancer patients in France. This study analyzed a representative random population sample from the French national healthcare insurance database, focusing on 1,612 patients with hematological or solid malignancies who were reimbursed in 2013 or 2014 for at least one G-CSF treatment dispensed in a retail pharmacy. Patient characteristics and treatment costs were analyzed according to the type of cancer. Then the costs and characteristics of patients associated with the use of different G-CSF products were analyzed in the sub-set of breast cancer patients. The most frequent malignancies in the database population were breast cancer (23.3%), hematological malignancies (22.2%), and lung cancer (12.4%). The reimbursed G-CSF was pegfilgrastim in 34.1% of cases, lenograstim in 26.7%, and filgrastim in 17.9%. More than one G-CSF product was reimbursed to 21.3% of patients. The total annual reimbursed health expenses per patient, according to the type of G-CSF, were €27,001, €24,511, and €20,802 for patients treated with filgrastim, lenograstim, and pegfilgrastim, respectively. Ambulatory care accounted for, respectively, 35%, 38%, and 41% of those costs. In patients with breast cancer, ambulatory care cost was €7,915 with filgrastim, €7,750 with lenograstim, and €6,989 with pegfilgrastim, and the respective cost of G-CSF was €1,733, €1,559, and €3,668. All available G-CSF products have been shown to be effective in cancer patients, and both daily G-CSFs and pegylated G-CSF are recommended in international guidelines. Nevertheless, this analysis of G-CSF reimbursement indicates that the choice of product can markedly affect the total cost of ambulatory care.

    To explore the barriers to requesting social and healthcare assistance perceived by transgender persons and professionals involved in the assistance. A meta-study, qualitative systematic review, of studies published in English or Spanish, exploring the barriers, perceived by transgender persons and social and healthcare professionals, that transgender persons have when they seek social and healthcare assistance was carried out in the following databases Medline (PubMed), Scopus, Web of Science, Spanish National Research Council, CUIDEN, ProQuest, PsycINFO and CINAHL. Two thousand two hundred and sixty-one articles were found in the databases searched. Seven articles met all inclusion criteria and were included in this review. The professionals highlight the uncertainty when treating transgender persons and their lack of training. Transgender persons highlight the lack of information and the sense of helplessness it creates. Perceptions of transphobia, the fragmentation of services, administrative barriers, the lack of cultural sensitivity and professional training are also considered barriers to assistance. The findings of this study provide key information for the design of plans and programmes to improve the quality of social and health care for transgender persons.

    Today's amount of freely available data requires scientists to spend large parts of their work on data management. This is especially true in environmental sciences when working with large remote sensing datasets, such as obtained from earth-observation satellites like the Sentinel fleet. Many frameworks like SpatialHadoop or Apache Spark address the scalability but target programmers rather than data analysts, and are not dedicated to imagery or array data. In this work, we use the open-source data management and analytics system SciDB to bring large earth-observation datasets closer to analysts. Its underlying data representation as multidimensional arrays fits naturally to earth-observation datasets, distributes storage and computational load over multiple instances by multidimensional chunking, and also enables efficient time-series based analyses, which is usually difficult using file- or tile-based approaches. Existing interfaces to R and Python furthermore allow for scalable analytics with relatively little learning effort. However, interfacing SciDB and file-based earth-observation datasets that come as tiled temporal snapshots requires a lot of manual bookkeeping during ingestion, and SciDB natively only supports loading data from CSV-like and custom binary formatted files, which currently limits its practical use in earth-observation analytics. To make it easier to work with large multi-temporal datasets in SciDB, we developed software tools that enrich SciDB with earth observation metadata and allow working with commonly used file formats: (i) the SciDB extension library scidb4geo simplifies working with spatiotemporal arrays by adding relevant metadata to the database and (ii) the Geospatial Data Abstraction Library (GDAL) driver implementation scidb4gdal allows to ingest and export remote sensing imagery from and to a large number of file formats. Using added metadata on temporal resolution and coverage, the GDAL driver supports time-based ingestion of

    Respect for patient autonomy is a cornerstone of contemporary medical ethics and clinical practice. In its different shapes and forms (e.g. being informed, being engaged in discussions and decisions about medical care and being supported in developing healthcare preferences and choices), patient autonomy has been fostered by both paediatric and adult professional societies. The transition from paediatric to adult care creates a complex situation where autonomy for medical decisions shifts to the developing adolescent. More specific challenges to respect for autonomy may be experienced by young adults with cerebral palsy in the transition period where, for example, language and motor impairments may affect communication skills and this may be conflated with cognitive disability. To characterize perspectives towards autonomy in the healthcare context for young adults with cerebral palsy. We carried out semi-structured interviews with 14 young adults (aged 18-25) with cerebral palsy. The audiotaped interviews were transcribed verbatim and analysed using a conventional thematic qualitative content analysis. Participants displayed a range of attitudes towards autonomy, suggesting that the value of autonomy is considered in light of competing values and of context. Testimonials from participants demonstrated that both contextual (e.g. ill-adapted health care, lack of specialized public transport) and relational (e.g. attitudes towards parental involvement in decision making) factors negatively or positively impact autonomy. We observed that there were four key elements interwoven in participants' characterization of autonomy: the coupling of decisional and physical autonomy, the influences of family and society on autonomy, the influence of healthcare professionals on autonomy and the need for preparation for autonomy. © 2012 John Wiley & Sons Ltd.

    Reducing readmission rates is vital to improving quality of care and reducing healthcare costs. In accordance with the Patient Protection and Affordable Care Act, Medicare will cut payments to hospitals with high 30-day readmission rates. We retrospectively reviewed an institutional database to identify risk factors predisposing adult cardiac surgery patients to rehospitalization within 30 days of discharge. Of 2302 adult cardiac surgery patients within the study period from 2008 to 2011, a total of 218 patients (9.5%) were readmitted within 30 days. Factors found to be significant predictors of readmission were nonwhite race (P = 0.003), government health insurance (P = 0.02), ejection fraction less than 40 per cent (P = 0.001), chronic lung disease (P < 0.001), and hospital length of stay greater than 7 days (P = 0.02). Patients undergoing aortic and mitral valve operations had an increased risk of readmission compared with other cardiac operations (P < 0.001). The most common reasons for rehospitalization were pneumonia and other respiratory complications (n = 27 [12.4%]). Recognition of risk factors is crucial to reducing readmissions and improving patient care. Our data suggest that optimizing cardiopulmonary status in patients with comorbidities such as heart failure and chronic obstructive pulmonary disease, increasing directed pneumonia prophylaxis, patient education tailored to specific patient social needs, earlier patient follow-up, and better communication between inpatient and outpatient physicians may reduce readmission rates.

    Technology management in healthcare must continually respond and adapt itself to new improvements in medical equipment. Multidisciplinary approaches which consider the interaction of different technologies, their use and user skills, are necessary in order to improve safety and quality. An easy and sustainable methodology is vital to Clinical Engineering (CE) services in healthcare organizations in order to define criteria regarding technology acquisition and replacement. This article underlines the critical aspects of technology management in hospitals by providing appropriate indicators for benchmarking CE services exclusively referring to the maintenance database from the CE department at the Careggi Hospital in Florence, Italy.

    A trusting relationship between patients, physicians, and the healthcare system is important in encouraging self-care behaviors in cardiovascular patients. The study aimed to assess the prevalence of healthcare system and physician distrust in this population, compare the two forms of distrust, and describe the demographic, socioeconomic, and psycho-social predictors of high distrust. 1232 hospitalized adults with acute coronary syndrome or heart failure were enrolled in a prospective, observational study assessing both healthcare system and physician distrust. High healthcare system distrust (35%) was observed across the population, with lower levels of interpersonal physician distrust (16%). In a multivariate analysis, poor social support and coping skills were strong predictors of both healthcare system (p = 0.026, p = 0.003) and physician distrust (p <0.001, p = 0.006). Individuals with low or marginal health literacy had a higher likelihood of physician distrust (p <0.001), but no relationship was found between health literacy and healthcare system distrust. In conclusion, distrust is common among acutely ill cardiac patients. Those with low social support and low coping skills are more distrusting of physicians and the healthcare system. PMID:25315583

    To review some common medical applications available for personal digital assistants (PDAs), with brief discussion of the different PDA operating systems and memory requirements. Key search terms included handheld, PDA, personal digital assistants, and medical applications. The literature was accessed through MEDLINE (1999-August 2002). Other information was obtained through secondary sources such as Web sites describing common PDAs. Medical applications available on PDAs are numerous and include general drug references, specialized drug references (e.g., pediatrics, geriatrics, cardiology, infectious disease), diagnostic guides, medical calculators, herbal medication references, nursing references, toxicology references, and patient tracking databases. Costs and memory requirements for these programs can vary; consequently, the healthcare provider must limit the medication applications that are placed on the handheld computer. This article attempts to systematically describe the common medical applications available for the handheld computer along with cost, memory and download requirements, and Web site information. This review found many excellent PDA drug information applications offering many features which will aid the healthcare provider. Very likely, after using these PDA applications, the healthcare provider will find them indispensable, as their multifunctional capabilities can save time, improve accuracy, and allow for general business procedures as well as being a quick reference tool. To avoid the benefits of this technology might be a step backward.

  13. Belgian health-related data in three international databases

    PubMed Central

    2011-01-01

    Aims of the study This study wants to examine the availability of Belgian healthcare data in the three main international health databases: the World Health Organization European Health for All Database (WHO-HFA), the Organisation for Economic Co-operation and Development Health Data 2009 and EUROSTAT. Methods For the indicators present in the three databases, the availability of Belgian data and the source of these data were checked. Main findings The most important problem concerning the availability of Belgian health-related data in the three major international databases is the lack of recent data. Recent data are available for 27% of the indicators of the WHO-HFA database, 73% of the OECD Health Data, and for half of the Eurostat indicators. Especially recent data about health status (including mortality-based indicators) are lacking. Discussion Only the availability of the health-related data is studied in this article. The quality of the Belgian data is however also important to examine. The main problem concerning the availability of health data is the timeliness. One of the causes of this lack of (especially mortality) data is the reform of the Belgian State. Nowadays mortality data are provided by the communities. This results in a delay in the delivery of national mortality data. However several efforts are made to catch up. PMID:22958554

    In this article, we make the etiologic diagnosis for a sick patient named Healthcare: the cancer of greed. When we explore the two forms of this cancer--corporate and bureaucratic--we find the latter is the greater danger to We the Patients. The "treatments" applied to patient Healthcare by the Congressional "doctors" have consistently made the patient worse, not better. At the core of healthcare's woes is the government's diversion of money from healthcare services to healthcare bureaucracy. As this is the root cause, it is what we must address in order to cure, not sedate or palliate, patient Healthcare.

    There is a critical gap in our nation's ability to accurately measure and manage the quality of medical care. A robust healthcare quality information system (HQIS) has the potential to address this deficiency through the capture, codification, and analysis of information about patient treatments and related outcomes. Because non-technical issues often present the greatest challenges, this paper provides an overview of these socio-technical issues in building a successful HQIS, including the human, organizational, and knowledge management (KM) perspectives. Through an extensive literature review and direct experience in building a practical HQIS (the National Comprehensive Cancer Network Outcomes Research Database system), we have formulated an “informatics blueprint” to guide the development of such systems. While the blueprint was developed to facilitate healthcare quality information collection, management, analysis, and reporting, the concepts and advice provided may be extensible to the development of other types of clinical research information systems.

    Compassion fatigue describes a work-related stress response in healthcare providers that is considered a 'cost of caring' and a key contributor to the loss of compassion in healthcare. The purpose of this review was to critically examine the construct of compassion fatigue and to determine if it is an accurate descriptor of work-related stress in healthcare providers and a valid target variable for intervention. Meta-narrative review. PubMed, Medline, CINAHL, PsycINFO, and Web of Science databases, Google Scholar, the grey literature, and manual searches of bibliographies. Seminal articles and theoretical and empirical studies on compassion fatigue in the healthcare literature were identified and appraised for their validity and relevance to our review. Sources were mapped according to the following criteria: 1) definitions; 2) conceptual analyses; 3) signs and symptoms; 4) measures; 5) prevalence and associated risk factors; and 6) interventions. A narrative account of included studies that critically examines the concept of compassion fatigue in healthcare was employed, and recommendations for practice, policy and further research were made. 90 studies from the nursing literature and healthcare in general were included in the review. Findings emphasized that the physical, emotional, social and spiritual health of healthcare providers is impaired by cumulative stress related to their work, which can impact the delivery of healthcare services; however, the precise nature of compassion fatigue and that it is predicated on the provision of compassionate care is associated with significant limitations. The conceptualization of compassion fatigue was expropriated from crisis counseling and psychotherapy and focuses on limited facets of compassion. Empirical studies primarily measure compassion fatigue using the Professional Quality of Life Scale, which does not assess any of the elements of compassion. Reported risk factors for compassion fatigue include job

    Healthcare is a knowledge driven process and thus knowledge management and the tools to manage knowledge in healthcare sector are gaining attention. The aim of this systematic review is to investigate knowledge management implementation and knowledge management tools used in healthcare for informed decision making. Three databases, two journals websites and Google Scholar were used as sources for the review. The key terms used to search relevant articles include: "Healthcare and Knowledge Management"; "Knowledge Management Tools in Healthcare" and "Community of Practices in healthcare". It was found that utilization of knowledge management in healthcare is encouraging. There exist numbers of opportunities for knowledge management implementation, though there are some barriers as well. Some of the opportunities that can transform healthcare are advances in health information and communication technology, clinical decision support systems, electronic health record systems, communities of practice and advanced care planning. Providing the right knowledge at the right time, i.e., at the point of decision making by implementing knowledge management in healthcare is paramount. To do so, it is very important to use appropriate tools for knowledge management and user-friendly system because it can significantly improve the quality and safety of care provided for patients both at hospital and home settings.

    Health literacy presents an enormous challenge in the delivery of effective healthcare and quality outcomes. We evaluated the impact of low health literacy (LHL) on healthcare utilization and healthcare expenditure. Database analysis used Medical Expenditure Panel Survey (MEPS) from 2005-2008 which provides nationally representative estimates of healthcare utilization and expenditure. Health literacy scores (HLSs) were calculated based on a validated, predictive model and were scored according to the National Assessment of Adult Literacy (NAAL). HLS ranged from 0-500. Health literacy level (HLL) and categorized in 2 groups: Below basic or basic (HLS <226) and above basic (HLS ≥226). Healthcare utilization expressed as a physician, nonphysician, or emergency room (ER) visits and healthcare spending. Expenditures were adjusted to 2010 rates using the Consumer Price Index (CPI). A P value of 0.05 or less was the criterion for statistical significance in all analyses. Multivariate regression models assessed the impact of the predicted HLLs on outpatient healthcare utilization and expenditures. All analyses were performed with SAS and STATA® 11.0 statistical software. The study evaluated 22 599 samples representing 503 374 648 weighted individuals nationally from 2005-2008. The cohort had an average age of 49 years and included more females (57%). Caucasian were the predominant racial ethnic group (83%) and 37% of the cohort were from the South region of the United States of America. The proportion of the cohort with basic or below basic health literacy was 22.4%. Annual predicted values of physician visits, nonphysician visits, and ER visits were 6.6, 4.8, and 0.2, respectively, for basic or below basic compared to 4.4, 2.6, and 0.1 for above basic. Predicted values of office and ER visits expenditures were $1284 and $151, respectively, for basic or below basic and $719 and $100 for above basic (P < .05). The extrapolated national estimates show that the annual

    Mental health is one of the responsibilities of Brazil's Family Health system. This review of literature sought to understand what position Mental Health occupies in the practice of the Family Health Strategy. A search was made of the scientific literature in the database of the Virtual Health Library (Biblioteca Virtual de Saúde), for the keywords: 'Mental Health'; 'Family Health'; 'Primary Healthcare'. The criteria for inclusion were: Brazilian studies from 2009 through 2012 that contributed to understanding of the following question: "How to insert Mental health care into the routine of the Family Health Strategy?" A total of 11 articles were found, which identified difficulties and strategies of the professionals in Primary Healthcare in relation to mental health. Referral, and medicalization, were common practices. Matrix Support is the strategy of training and skill acquisition for teams that enables new approaches in mental health in the context of Primary healthcare. It is necessary for Management of the Health System to take an active role in the construction of healthcare networks in mental health.

  20. Systematic review of methods for evaluating healthcare research economic impact

    PubMed Central

    2010-01-01

    Background The economic benefits of healthcare research require study so that appropriate resources can be allocated to this research, particularly in developing countries. As a first step, we performed a systematic review to identify the methods used to assess the economic impact of healthcare research, and the outcomes. Method An electronic search was conducted in relevant databases using a combination of specific keywords. In addition, 21 relevant Web sites were identified. Results The initial search yielded 8,416 articles. After studying titles, abstracts, and full texts, 18 articles were included in the analysis. Eleven other reports were found on Web sites. We found that the outcomes assessed as healthcare research payback included direct cost-savings, cost reductions in healthcare delivery systems, benefits from commercial advancement, and outcomes associated with improved health status. Two methods were used to study healthcare research payback: macro-economic studies, which examine the relationship between research studies and economic outcome at the aggregated level, and case studies, which examine specific research projects to assess economic impact. Conclusions Our study shows that different methods and outcomes can be used to assess the economic impacts of healthcare research. There is no unique methodological approach for the economic evaluation of such research. In our systematic search we found no research that had evaluated the economic return of research in low and middle income countries. We therefore recommend a consensus on practical guidelines at international level on the basis of more comprehensive methodologies (such as Canadian Academic of Health Science and payback frameworks) in order to build capacity, arrange for necessary informative infrastructures and promote necessary skills for economic evaluation studies.

    This study describes which clinical ethics approaches are available to support healthcare personnel in clinical practice in terms of their construction, functions and goals. Healthcare personnel frequently face ethically difficult situations in the course of their work and these issues cover a wide range of areas from prenatal care to end-of-life care. Although various forms of clinical ethics support have been developed, to our knowledge there is a lack of review studies describing which ethics support approaches are available, how they are constructed and their goals in supporting healthcare personnel in clinical practice. This study engages in an integrative literature review. We searched for peer-reviewed academic articles written in English between 2000 and 2016 using specific Mesh terms and manual keywords in CINAHL, MEDLINE and Psych INFO databases. In total, 54 articles worldwide described clinical ethics support approaches that include clinical ethics consultation, clinical ethics committees, moral case deliberation, ethics rounds, ethics discussion groups, and ethics reflection groups. Clinical ethics consultation and clinical ethics committees have various roles and functions in different countries. They can provide healthcare personnel with advice and recommendations regarding the best course of action. Moral case deliberation, ethics rounds, ethics discussion groups and ethics reflection groups support the idea that group reflection increases insight into ethical issues. Clinical ethics support in the form of a "bottom-up" perspective might give healthcare personnel opportunities to think and reflect more than a "top-down" perspective. A "bottom-up" approach leaves the healthcare personnel with the moral responsibility for their choice of action in clinical practice, while a "top-down" approach risks removing such moral responsibility.

    Faced with long waiting lists, the high cost of elective treatment and fewer barriers to travel, the idea of availing healthcare in another country is gaining greater appeal to many. The objective of this review is to perform a literature review of health and medical tourism, to define health and medical tourism based on the medical literature and to estimate the size of trade in healthcare. The Medline database was used for our literature review. In our initial search for 'health tourism' and 'medical tourism' we found a paucity of formal literature as well as conceptual ambiguity in the literature. Subsequently, we reviewed the literature on 'tourism' in general and in the context of healthcare. On the basis of 149 papers, we then sought to conceptualize health tourism and medical tourism. Based on our definitions, we likewise sought to estimate market capacity internationally. We defined health tourism as "the organized travel outside one's local environment for the maintenance, enhancement or restoration of an individual's wellbeing in mind and body". A subset of this is medical tourism, which is "the organized travel outside one's natural healthcare jurisdiction for the enhancement or restoration of the individual's health through medical intervention". At the international level, health tourism is an industry sustained by 617 million individuals with an annual growth of 3.9% annually and worth US$513 billion. In conclusion, this paper underscored the issue of a severely limited formal literature that is compounded by conceptual ambiguity facing health and medical tourism scholarship. In clarifying the concepts and standardizing definitions, and providing evidence with regard to the scale of trade in healthcare, we hope to assist in furthering fundamental research tasks, including the further development of reliable and comparable data, the push and pull factors for engaging in health and medical tourism, and the impact of health tourism but, more so, medical

    Background Truck drivers have unique health needs, and by virtue of their continuous travel, experience difficulty in accessing healthcare. Currently, planning for effective care is hindered by lack of knowledge about their health needs and about the impact of on-going programmes on this population’s health outcomes. We reviewed healthcare programmes implemented for sub-Saharan African truck drivers, assessed the evaluation methods, and examined impact on health outcomes. Methods We searched scientific and institutional databases, and online search engines to include all publications describing a healthcare programme in sub-Saharan Africa where the main clients were truck drivers. We consulted experts and organisations working with mobile populations to identify unpublished reports. Forest plots of impact and outcome indicators with unadjusted risk ratios and 95% confidence intervals were created to map the impact of these programmes. We performed a subgroup analysis by type of indicator using a random-effects model to assess between-study heterogeneity. We conducted a sensitivity analysis to examine both the summary effect estimate chosen (risk difference vs. risk ratio) and model to summarise results (fixed vs. random effects). Results Thirty-seven publications describing 22 healthcare programmes across 30 countries were included from 5,599 unique records. All programmes had an HIV-prevention focus with only three expanding their services to cover conditions other primary healthcare services. Twelve programmes were evaluated and most evaluations assessed changes in input, output, and outcome indicators. Absence of comparison groups, preventing attribution of the effect observed to the programme and lack of biologically confirmed outcomes were the main limitations. Four programmes estimated a quantitative change in HIV prevalence or reported STI incidence, with mixed results, and one provided anecdotal evidence of changes in AIDS-related mortality and social

    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.

    Remote UV measurement of the outer planets offer a wealth of informations on rings, moons, planetary atmospheres and magnetospheres. Auroral emissions in particular provide highly valuable constraints on the auroral processes at work and the underlying coupling between the solar wind, the magnetosphere, the ionosphere and the moons. Key observables provided by high resolution spectro-imaging include the spatial topology and the dynamics of active magnetic field lines, the radiated and the precipitated powers or the energy of precipitating particles. The Hubble Space Telescope (HST) acquired thousands of Far-UV spectra and images of the aurorae of Jupiter, Saturn and Uranus since 1993, feeding in numerous magnetospheric studies. But their use remains generally limited, owing to the difficulty to access and use raw and value-added data. APIS, the egyptian god of fertilization, is also the acronym of a new database (Auroral Planetary Imaging and Spectroscopy), aimed at facilitating the use of HST planetary auroral observations. APIS is based at the Virtual Observatory (VO) of Paris and provides a free and interactive access to a variety of high level data through a simple research interface and standard VO tools (as Aladin, Specview). We will present the capabilities of APIS and illustrate them with several examples.

    To explore and synthesize evidence of the literature about healthcare professionals involved in the provision of diabetes management within an Indonesian context. Indonesia is challenged to control the major burden of diabetes prevalence rate that requires a multidimensional approach with the aim to optimize existing health services by involving healthcare professionals who can promote access and provide diabetes management. This literature review, which is integrated with a scoping study framework, used the electronic databases including CINAHL, PubMed, Scopus and Web of Science to locate papers particular to the Indonesian context. From the total of 568 papers found, 20 papers were selected. The literature review identified physicians, nurses, pharmacists, dieticians and diabetes educators as the providers of diabetes care and management in Indonesia. Collaborative management involving either interdisciplinary or intradisciplinary teams was mentioned in several papers. Internal challenges included limited skills and knowledge. External challenges included high patient volumes; a shortage of healthcare professionals and reduced funding. Overcoming the challenges cannot be undertaken with a workforce dominated by any one single healthcare professional. Coordinating with the government to improve the implementation of different roles in diabetes management will improve patient outcomes and thus reduce the burden of diabetes. Health policy reform should support nurses and other healthcare professionals in their professional development at all levels of health care. Policy makers can use the review findings to modify the current healthcare system to address key issues in workforce development; funding for services and medications; and fostering multidisciplinary care for diabetes management. © 2018 International Council of Nurses.

    The Learning Healthcare System paradigm has attracted the attention of researchers worldwide. The great potential originating from high-scale health data reuse and the inclusion of patient perspectives into care models promises personalized care, lower costs of health services and minimized consumption of resources. The aim of this review is to summarize the attempts to adopt the novel paradigm, putting emphasis on implementations and evaluating the impact on current medical practices. PRISMA methodology was followed for structuring the review process. Three major research databases (PubMed, IEEE Xplore and ACM DL) were queried with the predefined search terms "learning healthcare" and "learning health". Publications containing specific theoretical or empirical results were considered. Three hundred and fifty-eight publications were identified; however, only 32 met the inclusion criteria. Nineteen papers were characterized as theoretical contributions, while the rest presented empirical achievements. Only one paper described the initial estimates of impact and economy. Individualistic communication of studies ignoring popular frameworks for assessing and reporting research achievements prevents the systematic generation of knowledge. Evaluating the impact of the Learning Healthcare System instances where it is implemented could work as a catalyst in reaching higher acceptance and adoption of the proposed ideas by healthcare worldwide; however, it mostly remains described in theory. The review demonstrated the interest of researchers in exploring the Learning Healthcare System ideas. However, it also revealed minimal focus on evaluating the impact of the novel paradigm on both healthcare service delivery and patient outcome. Copyright © 2016 Elsevier Inc. All rights reserved.

    What are the costs and utilisation of healthcare resources, their determinants, and quality of life for people attending outpatient physiotherapy after ankle fracture? Longitudinal observational study. Ninety-four adults (2 dropouts) following cast removal after isolated ankle fracture attending outpatient physiotherapy at three hospitals in Sydney, Australia. Costs incurred (direct healthcare costs and out-of-pocket costs) and utilisation of healthcare system resources were measured at 4, 8, 12, 16, 20, and 24 weeks. Quality of life was measured shortly after cast removal and at 4, 12, and 24 weeks. Factors known to influence costs and utilisation in other conditions (private health insurance, income level, gender, and pain) were also measured. The total cost per person was AUD 735 (SD 876) over 24 weeks. Outpatient physiotherapy accounted for the highest costs in both direct healthcare (39%) and out-of-pocket (42%) costs. Less than 20% of participants sought private non-medical care in addition to receiving outpatient physiotherapy. None of the factors investigated had a significant influence on costs and utilisation. Quality of life score improved over the 24 weeks by a mean of 6.1 points out of 45 (95% CI 5.2 to 6.9), with most of the improvement occurring in the domain of independent living. Information on costs and utilisation of healthcare resources can be used to plan health services, eg, the number of physiotherapy sessions required after ankle fracture. Private health insurance, income level, gender, or pain did not influence the costs or the decision behind seeking care over and above publicly-provided physiotherapy.

    This evaluative research study aimed to assess the effects of the central healthcare incinerator project on waste management in Yala Province. The study data were collected twice: at baseline and during the operational phase. A combination of structured interview and observation were used during data collection. The study covered 127 healthcare facilities: government hospitals, healthcare centres, and private clinics. The results showed 63% of healthcare risk waste (HCRW) handlers attended the HCRW management training. Improvements in each stage of the HCRW management system were observed in all groups of facilities. The total cost of the HCRW management system did not change, however; the costs for hospitals decreased, whereas those for clinics increased significantly. It was concluded that the central healthcare waste incinerator project positively affected HCRW management in the area, although the costs of management might increase for a particular group. However, the benefits of changing to a more appropriately managed HCRW system will outweigh the increased costs.

    The authors tested the prevalent hypothesis that forensic use of medical biobanks has a negative impact on public trust in healthcare services. A questionnaire was sent to 1,184 inhabitant in the age group 20-80 years in Stockholm County, Sweden, in November 2005. With a response rate of 68.4%, the results showed that a majority (88.1%) of the respondents thought that it would be acceptable for the police to gain access to genetic samples stored in relation to healthcare; 5.6% said no and 6.3% were uncertain. In the case of police access to medical biobanks, a minority (6.3%) indicated that this would have a negative impact on their trust, a larger proportion (37.8%) that it would influence their trust in the healthcare services positively, and 56% stated that it would not affect their trust at all. The hypothesis tested appears to be unfounded. This should cause us to reconsider prevalent assumptions and current policies on the interface of medical and forensic genetics.

    This article presents a model of the healthcare value chain which consists of a schematic representation of the Brazilian healthcare system. The proposed model is adapted for the Brazilian reality and has the scope and flexibility for use in academic activities and analysis of the healthcare sector in Brazil. It places emphasis on three components: the main activities of the value chain, grouped in vertical and horizontal links; the mission of each link and the main value chain flows. The proposed model consists of six vertical and three horizontal links, amounting to nine. These are: knowledge development; supply of products and technologies; healthcare services; financial intermediation; healthcare financing; healthcare consumption; regulation; distribution of healthcare products; and complementary and support services. Four flows can be used to analyze the value chain: knowledge and innovation; products and services; financial; and information.

    Since over 10 years, the Lombardy Region (Italy) has developed a system for classifying all persons registered with the healthcare system (database of persons registered with a general practitioner), according to their use of major healthcare services (hospitalizations, outpatient consultations, pharmaceutical) and whether they are exempt from copayment fees for disease-specific medications and healthcare services. The present study was conducted by the local health authorities of the province of Varese (Lombardy region, Italy) with 894.039 persons registered in the database of whom 258.770 (28.9%) with at least one chronic condition, 104.731 (11.7%) with multiple chronic conditions and 195.296 (21.8%) elderly persons. The aim was to evaluate death rates in different subgroups of patients entered in the database, including persons with chronic diseases and elderly persons. Standardized mortality rates were calculated for the year 2012. Compared with the general population, relative risk for mortality was 4,1 (95% confidence Intervals 4,0-4,2) in the elderly and 1,3 (95% confidence intervals 1,3-1,4) in chronic patients. This confirms that elderly persons have a higher level of frailty with respect to patients with chronic conditions. Mortality was found to be 28 times higher in elderly persons over 74 years of age, affected by high cost conditions such as cancer and cardiac disease, with respect to the general population.

    2011-01-01

    Provision of ubiquitous healthcare solutions which provide healthcare services at anytime anywhere has become more favorable nowadays due to the emphasis on healthcare awareness and also the growth of mobile wireless technologies. Following this approach, an Android™ smart phone device is proposed as a mobile monitoring terminal to observe and analyze ECG (electrocardiography) waveforms from wearable ECG devices in real time under the coverage of a wireless sensor network (WSN). The exploitation of WSN in healthcare is able to substitute the complicated wired technology, moving healthcare away from a fixed location setting. As an extension to the monitoring scheme, medicine care is taken into consideration by utilizing the mobile phone as a barcode decoder, to verify and assist out-patients in the medication administration process, providing a better and more comprehensive healthcare service.

    We have no clear overview of the extent to which health-care providers involve patients in the decision-making process during consultations. The Observing Patient Involvement in Decision Making instrument (OPTION) was designed to assess this. To systematically review studies that used the OPTION instrument to observe the extent to which health-care providers involve patients in decision making across a range of clinical contexts, including different health professions and lengths of consultation. We conducted online literature searches in multiple databases (2001-12) and gathered further data through networking. (i) OPTION scores as reported outcomes and (ii) health-care providers and patients as study participants. For analysis, we only included studies using the revised scale. Extracted data included: (i) study and participant characteristics and (ii) OPTION outcomes (scores, statistical associations and reported psychometric results). We also assessed the quality of OPTION outcomes reporting. We found 33 eligible studies, 29 of which used the revised scale. Overall, we found low levels of patient-involving behaviours: in cases where no intervention was used to implement shared decision making (SDM), the mean OPTION score was 23 ± 14 (0-100 scale). When assessed, the variables most consistently associated with higher OPTION scores were interventions to implement SDM (n = 8/9) and duration of consultations (n = 8/15). Whatever the clinical context, few health-care providers consistently attempt to facilitate patient involvement, and even fewer adjust care to patient preferences. However, both SDM interventions and longer consultations could improve this. © 2013 John Wiley & Sons Ltd.

    The research aims to explore the association between behavioral habits and chronic diseases, and to identify a portfolio of risk factors for preventive healthcare. The data is taken from the Behavioral Risk Factor Surveillance System (BRFSS) database of the Centers for Disease Control and Prevention, for the year 2012. Using SPSS Modeler, we deploy neural networks to identify strong positive and negative associations between certain chronic diseases and behavioral habits. The data for 475,687 records from BRFS database included behavioral habit variables of consumption of soda and fruits/vegetables, alcohol, smoking, weekly working hours, and exercise; chronic disease variables of heart attack, stroke, asthma, and diabetes; and demographic variables of marital status, income, and age. Our findings indicate that with chronic conditions, behavioral habits of physical activity and fruit and vegetable consumption are negatively associated; soda, alcohol, and smoking are positively associated; and income and age are positively associated. We contribute to individual and national preventive healthcare by offering a portfolio of significant behavioral risk factors that enable individuals to make lifestyle changes and governments to frame campaigns and policies countering chronic conditions and promoting public health.

In recent years, increasing emphasis has been placed on the need to change organisational culture in order to improve healthcare performance. However, the precise function of organisational culture in healthcare policy often remains underspecified and the desirability and feasibility of strategies to be adopted have been called into question. The objective of this review was to determine the effectiveness of strategies to change organisational culture in order to improve healthcare performance. We searched the following electronic databases: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, Sociological Abstracts, Web of Knowledge, PsycINFO, Business and Management, EThOS, Index to Theses, Intute, HMIC, SIGLE, and Scopus until October 2009. The Database of Abstracts of Reviews of Effectiveness (DARE) was searched for related reviews. We also searched the reference lists of all papers and relevant reviews identified, and we contacted experts in the field for advice on further potential studies. We considered randomised controlled trials (RCTs) or well designed quasi-experimental studies (controlled clinical trials (CCTs), controlled before and after studies (CBAs), and interrupted time series (ITS) analyses).

    To report an analysis of the concept of shared mental models in health care. Shared mental models have been described as facilitators of effective teamwork. The complexity and criticality of the current healthcare system requires shared mental models to enhance safe and effective patient/client care. Yet, the current concept definition in the healthcare literature is vague and, therefore, difficult to apply consistently in research and practice. Concept analysis. Literature for this concept analysis was retrieved from several databases, including CINAHL, PubMed and MEDLINE (EBSCO Interface), for the years 1997-2013. Walker and Avant's approach to concept analysis was employed and, following Paley's guidance, embedded in extant theory from the team literature. Although teamwork and collaboration are discussed frequently in healthcare literature, the concept of shared mental models in that context is not as commonly found but is increasing in appearance. Our concept analysis defines shared mental models as individually held knowledge structures that help team members function collaboratively in their environments and are comprised of the attributes of content, similarity, accuracy and dynamics. This theoretically grounded concept analysis provides a foundation for a middle-range descriptive theory of shared mental models in nursing and health care. Further research concerning the impact of shared mental models in the healthcare setting can result in development and refinement of shared mental models to support effective teamwork and collaboration. © 2013 John Wiley & Sons Ltd.

    Background Measures of healthcare utilization and indirect impact of asthma morbidity are used to assess clinical interventions and estimate cost. Objective National Institutes of Health (NIH) institutes and other federal agencies convened an expert group to propose standardized measurement, collection, analysis, and reporting of healthcare utilization and cost outcomes in future asthma studies. Methods We used comprehensive literature reviews and expert opinion to compile a list of asthma healthcare utilization outcomes that we classified as core (required in future studies), supplemental (used according to study aims and standardized) and emerging (requiring validation and standardization). We also have identified methodology to assign cost to these outcomes. This work was discussed at an NIH-organized workshop in March 2010 and finalized in September 2011. Results We identified 3 ways to promote comparability across clinical trials for measures of healthcare utilization, resource use, and cost: (1) specify the study perspective (patient, clinician, payer, society), (2) standardize the measurement period (ideally, 12 months), and (3) use standard units to measure healthcare utilization and other asthma-related events. Conclusions Large clinical trials and observational studies should collect and report detailed information on healthcare utilization, intervention resources, and indirect impact of asthma, so that costs can be calculated and cost-effectiveness analyses can be conducted across several studies. Additional research is needed to develop standard, validated survey instruments for collection of provider-reported and participant-reported data regarding asthma-related health care. PMID:22386509

    Measurement and monitoring of the quality of care using a core set of quality measures are increasing in health service research. Although administrative databases include limited clinical data, they offer an attractive source for quality measurement. The purpose of this study, therefore, was to evaluate the completeness of different administrative data sources compared to a clinical survey in evaluating rectal cancer cases. Between May 2012 and November 2014, a clinical survey was done on 498 Lombardy patients who had rectal cancer and underwent surgical resection. These collected data were compared with the information extracted from administrative sources including Hospital Discharge Dataset, drug database, daycare activity data, fee-exemption database, and regional screening program database. The agreement evaluation was performed using a set of 12 quality indicators. Patient complexity was a difficult indicator to measure for lack of clinical data. Preoperative staging was another suboptimal indicator due to the frequent missing administrative registration of tests performed. The agreement between the 2 data sources regarding chemoradiotherapy treatments was high. Screening detection, minimally invasive techniques, length of stay, and unpreventable readmissions were detected as reliable quality indicators. Postoperative morbidity could be a useful indicator but its agreement was lower, as expected. Healthcare administrative databases are large and real-time collected repositories of data useful in measuring quality in a healthcare system. Our investigation reveals that the reliability of indicators varies between them. Ideally, a combination of data from both sources could be used in order to improve usefulness of less reliable indicators.

    The proposal database and scheduling system for the Extreme Ultraviolet Explorer is described. The proposal database has been implemented to take input for approved observations selected by the EUVE Peer Review Panel and output target information suitable for the scheduling system to digest. The scheduling system is a hybrid of the SPIKE program and EUVE software which checks spacecraft constraints, produces a proposed schedule and selects spacecraft orientations with optimal configurations for acquiring star trackers, etc. This system is used to schedule the In Orbit Calibration activities that took place this summer, following the EUVE launch in early June 1992. The strategy we have implemented has implications for the selection of approved targets, which have impacted the Peer Review process. In addition, we will discuss how the proposal database, founded on Sybase, controls the processing of EUVE Guest Observer data.

    To describe costs, healthcare resource utilization, and adherence of US patients receiving human regular U-500 insulin (U-500R), compared to patients receiving high-dose (>200 units/day) U-100 insulins (U-100) by subcutaneous injection for the treatment of diabetes. A retrospective analysis of data from Thomson Reuters MarketScan Research Databases (7/1/2008 to 12/31/2010). Difference-in-differences analyses were conducted on cost (medical, pharmacy, and overall costs) and on healthcare resource utilization variables (overall, diabetes-related, and non-diabetes-related medical visits). Adherence rates to the index insulins were assessed by proportion of days covered (PDC). Seven hundred and eleven (19%) patients in the U-500R cohort and 1508 (6%) patients in the U-100 cohort met selection criteria. Propensity score matching resulted in 684 matched pairs. Mean change in annualized pharmacy costs was in favor of the U-500R vs the U-100 cohort (-$1258 vs $3345, a difference of -$4603, p < 0.0001). Mean overall cost increase in the U-500R vs the U-100 cohort was also lower ($1999 vs $9104, a difference of -$7105, p = 0.005). The proportion of patients with at least one coded hypoglycemic event during the 12-month post-index period was higher in the U-500R vs the U-100 cohort (17.1% vs 11.7%, p < 0.005), but neither hypoglycemia rate (2.73 vs 2.90 events per person) nor hypoglycemia-specific costs (mean $1669 vs $1543) were significantly different. No significant differences were noted between cohorts for change (post-pre) in any resource utilization category. PDC was greater in the U-500R vs the U-100 cohort (65.2% vs 39.5%, p < 0.0001). Claims data are not as accurate as empirical evaluation by a clinician. Glycemic control data were not available for this analysis. In patients requiring high-dose insulin, treatment with U-500R vs high-dose U-100 insulins is associated with significant decreases in pharmacy and overall costs, slightly higher

    Enhancing the use of existing datasets within acute hospitals will greatly facilitate hospital epidemiology, surveillance, the monitoring of a variety of processes, outcomes and risk factors, and the provision of alert systems. Multiple overlapping data systems exist within National Health Service (NHS) hospitals in the UK, and many duplicate data recordings take place because of the lack of linkage and interfaces. This results in hospital-collected data not being used efficiently. The objective was to create an inventory of all existing systems, including administrative, management, human resources, microbiology, patient care and other platforms, to describe the data architecture that could contribute valuable information for a hospital epidemiology unit. These datasets were investigated as to how they could be used to generate surveillance data, key performance indicators and risk information that could be shared at board, clinical programme group, specialty and ward level. An example of an output of this integrated data platform and its application in influenza resilience planning and responsiveness is described. The development of metrics for staff absence and staffing levels may also be used as key indicators for risk-monitoring for infection prevention. This work demonstrates the value of such a data inventory and linkage and the importance of more sophisticated uses of existing NHS data, and innovative collaborative approaches to support clinical care, quality improvement, surveillance, emergency planning and research.

    Healthcare facility hand hygiene impacts patient care, healthcare worker safety, and infection control, but low-income countries have few data to guide interventions. To conduct a nationally representative survey of hand hygiene infrastructure and behaviour in Bangladeshi healthcare facilities to establish baseline data to aid policy. The 2013 Bangladesh National Hygiene Baseline Survey examined water, sanitation, and hand hygiene across households, schools, restaurants and food vendors, traditional birth attendants, and healthcare facilities. We used probability proportional to size sampling to select 100 rural and urban population clusters, and then surveyed hand hygiene infrastructure in 875 inpatient healthcare facilities, observing behaviour in 100 facilities. More than 96% of facilities had 'improved' water sources, but environmental contamination occurred frequently around water sources. Soap was available at 78-92% of handwashing locations for doctors and nurses, but just 4-30% for patients and family. Only 2% of 4676 hand hygiene opportunities resulted in recommended actions: using alcohol sanitizer or washing both hands with soap, then drying by air or clean cloth. Healthcare workers performed recommended hand hygiene in 9% of 919 opportunities: more after patient contact (26%) than before (11%). Family caregivers frequently washed hands with only water (48% of 2751 opportunities), but with little soap (3%). Healthcare workers had more access to hand hygiene materials and performed better hand hygiene than family, but still had low adherence. Increasing hand hygiene materials and behaviour could improve infection control in Bangladeshi healthcare facilities. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Healthcare Architecture in Hong Kong is in an on-going process of metamorphosis in response to the social, economical and technological developments in the territory. In the process of transformation, universal problems like obsolescence, growth and expansion, and advances in science and technology as well as problems unique to Hong Kong like population growth, scarcity in land supply and high density development all call for special solutions. With the turn of the century, new forces of change have also begun to take shape, and in anticipation of the hyper-turbulent changes ahead, we need to shift our paradigm to allow revolutionary new perspectives and innovate, shape and create the future healing space which is sustainable, adaptable, flexible and humane.

    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.

    Background: Individuals with multiple sclerosis (MS) face a range of barriers to accessing and using health-care services. The aim of this review was to identify specific barriers to accessing and using health-care services based on a continuum of the health-care delivery system. Methods: Literature searches were conducted in the PubMed, PsycINFO, CINAHL, and Web of Science databases. The following terms were searched as subject headings, key words, or abstracts: health care, access, barriers, physical disability, and multiple sclerosis. The literature search produced 361 potentially relevant citations. After screening titles, abstracts, and citations, eight citations were selected for full-text review. Results: Health-care barriers were divided into three continuous phases of receiving health care. In the before-visit phase, the most commonly identified barrier was transportation. In the during-visit phase, communication quality was the major concern. In the after-visit phase, discontinued referral was the major barrier encountered. Conclusions: There are multiple interrelated barriers to accessing and using health-care services along the health-care delivery continuum for people with MS and its associated physical disabilities, ranging from complex and long-recognized barriers that will likely require extended advocacy to create policy changes to issues that can and should be addressed through relatively minor changes in health-care delivery practices, improved care coordination, and increased provider awareness, education, and responsiveness to patients' needs.

    Multi-tasking is an important skill for clinical work which has received limited research attention. Its impacts on clinical work are poorly understood. In contrast, there is substantial multi-tasking research in cognitive psychology, driver distraction, and human-computer interaction. This review synthesises evidence of the extent and impacts of multi-tasking on efficiency and task performance from health and non-healthcare literature, to compare and contrast approaches, identify implications for clinical work, and to develop an evidence-informed framework for guiding the measurement of multi-tasking in future healthcare studies. The results showed healthcare studies using direct observation have focused on descriptive studies to quantify concurrent multi-tasking and its frequency in different contexts, with limited study of impact. In comparison, non-healthcare studies have applied predominantly experimental and simulation designs, focusing on interleaved and concurrent multi-tasking, and testing theories of the mechanisms by which multi-tasking impacts task efficiency and performance. We propose a framework to guide the measurement of multi-tasking in clinical settings that draws together lessons from these siloed research efforts. Copyright © 2016 The Authors.

With the number of employees in healthcare rising and an overwhelming proportion of this workforce being female, it is important to address this issue in this growing sector. To determine whether compensated work-related injuries among females are higher than their male colleagues in the British Columbia healthcare sector. Incidents of occupational injury resulting in compensated days lost from work over a 1-year period for all healthcare workers were extracted from a standardized operational database and the numbers of productive hours were obtained from payroll data. Injuries were grouped into all injuries and musculoskeletal injuries (MSIs). Detailed analysis was conducted using Poisson regression modelling. A total of 42 332 employees were included in the study of whom 11% were male and 89% female. When adjusted for age, occupation, sub-sector, employment category, health region and facility, female workers had significantly higher risk of all injuries [rate ratio (95% CI) = 1.58 (1.24-2.01)] and MSIs [1.43 (1.11-1.85)] compared to their male colleagues. Occupational health and safety initiatives should be gender sensitive and developed accordingly.

    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

  1. Strategies for medical data extraction and presentation part 2: creating a customizable context and user-specific patient reference database.

    One of the greatest challenges facing healthcare professionals is the ability to directly and efficiently access relevant data from the patient's healthcare record at the point of care; specific to both the context of the task being performed and the specific needs and preferences of the individual end-user. In radiology practice, the relative inefficiency of imaging data organization and manual workflow requirements serves as an impediment to historical imaging data review. At the same time, clinical data retrieval is even more problematic due to the quality and quantity of data recorded at the time of order entry, along with the relative lack of information system integration. One approach to address these data deficiencies is to create a multi-disciplinary patient referenceable database which consists of high-priority, actionable data within the cumulative patient healthcare record; in which predefined criteria are used to categorize and classify imaging and clinical data in accordance with anatomy, technology, pathology, and time. The population of this referenceable database can be performed through a combination of manual and automated methods, with an additional step of data verification introduced for data quality control. Once created, these referenceable databases can be filtered at the point of care to provide context and user-specific data specific to the task being performed and individual end-user requirements.

    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.

    The EU expanded in 2004 to include eight transition countries, i.e. Central and Eastern European (CEE) and newly independent states of the former Soviet Union, and two other CEE countries are scheduled to join the EU in 2007. Each of these countries has undertaken substantial healthcare reform efforts over the past 15 years. The paths of healthcare reform are diverse for a number of reasons including differences in initial economic, political and structural conditions. The objective of this article is to evaluate the process and preliminary outcomes of healthcare reform in the new EU and candidate countries by analysing trends in aggregate financing, supply and utilisation indicators using data drawn from the WHO Health for All database. The analysis is done in the context of an analytical framework built around common healthcare reform themes. The key reform measures examined include implementing social insurance systems, implementing payment systems that promote efficiency, and removal of excess capacity. The trend analysis highlights the importance of the economic, political and social context in driving the direction and pace of healthcare reform. For example, the transition to social insurance systems was smoother in countries with stronger economies and political commitment to reform. Policies aimed at improving the efficiency of the healthcare system, reducing utilisation and reducing excess capacity were met with some success in all of the countries. However, the reform effort continues as the countries are still addressing the initial challenges of insufficient funding, informal payments, excess capacity and inefficiencies in the provision of healthcare.

    This article reviews the peer-reviewed literature addressing the healthcare information available on YouTube. Inclusion and exclusion criteria were determined, and the online databases PubMed and Web of Knowledge were searched using the search phrases: (1) YouTube* AND Health* and (2) YouTube* AND Healthcare*. In all, 18 articles were reviewed, with the results suggesting that (1) YouTube is increasingly being used as a platform for disseminating health information; (2) content and frame analysis were the primary techniques employed by researchers to analyze the characteristics of this information; (3) YouTube contains misleading information, primarily anecdotal, that contradicts the reference standards and the probability of a lay user finding such content is relatively high; (4) the retrieval of relevant videos is dependent on the search term used; and (5) videos from government organizations and professional associations contained trustworthy and high-quality information. YouTube is used as a medium for promoting unscientific therapies and drugs that are yet to be approved by the appropriate agencies and has the potential to change the beliefs of patients concerning controversial topics such as vaccinations. This review recognizes the need to design interventions to enable consumers to critically assimilate the information posted on YouTube with more authoritative information sources to make effective healthcare decisions. © The Author(s) 2014.

    Numerous studies examine simulation modelling in healthcare. These studies present a bewildering array of simulation techniques and applications, making it challenging to characterise the literature. The aim of this paper is to provide an overview of the level of activity of simulation modelling in healthcare and the key themes. We performed an umbrella review of systematic literature reviews of simulation modelling in healthcare. Searches were conducted of academic databases (JSTOR, Scopus, PubMed, IEEE, SAGE, ACM, Wiley Online Library, ScienceDirect) and grey literature sources, enhanced by citation searches. The articles were included if they performed a systematic review of simulation modelling techniques in healthcare. After quality assessment of all included articles, data were extracted on numbers of studies included in each review, types of applications, techniques used for simulation modelling, data sources and simulation software. The search strategy yielded a total of 117 potential articles. Following sifting, 37 heterogeneous reviews were included. Most reviews achieved moderate quality rating on a modified AMSTAR (A Measurement Tool used to Assess systematic Reviews) checklist. All the review articles described the types of applications used for simulation modelling; 15 reviews described techniques used for simulation modelling; three reviews described data sources used for simulation modelling; and six reviews described software used for simulation modelling. The remaining reviews either did not report or did not provide enough detail for the data to be extracted. Simulation modelling techniques have been used for a wide range of applications in healthcare, with a variety of software tools and data sources. The number of reviews published in recent years suggest an increased interest in simulation modelling in healthcare.

  7. Just healthcare? The moral failure of single-tier basic healthcare.

    PubMed

    Meadowcroft, John

    2015-04-01

    This article sets out the moral failure of single-tier basic healthcare. Single-tier basic healthcare has been advocated on the grounds that the provision of healthcare should be divorced from ability to pay and unequal access to basic healthcare is morally intolerable. However, single-tier basic healthcare encounters a host of catastrophic moral failings. Given the fact of human pluralism it is impossible to objectively define "basic" healthcare. Attempts to provide single-tier healthcare therefore become political processes in which interest groups compete for control of scarce resources with the most privileged possessing an inherent advantage. The focus on outputs in arguments for single-tier provision neglects the question of justice between individuals when some people provide resources for others without reciprocal benefits. The principle that only healthcare that can be provided to everyone should be provided at all leads to a leveling-down problem in which advocates of single-tier provision must prefer a situation where some individuals are made worse-off without any individual being made better-off compared to plausible multi-tier alternatives. Contemporary single-tier systems require the exclusion of noncitizens, meaning that their universalism is a myth. In the light of these pathologies, it is judged that multi-tier healthcare is morally required. © The Author 2015.

    Introduction Magnitude and frequency of HIV viral load blips in resource-limited settings, has not previously been assessed. This study was undertaken in a cohort from a high income country (Australia) known as AHOD (Australian HIV Observational Database) and another cohort from a mixture of Asian countries of varying national income per capita, TAHOD (TREAT Asia HIV Observational Database). Methods Blips were defined as detectable VL (≥ 50 copies/mL) preceded and followed by undetectable VL (<50 copies/mL). Virological failure (VF) was defined as two consecutive VL ≥50 copies/ml. Cox proportional hazard models of time to first VF after entry, were developed. Results 5040 patients (AHOD n = 2597 and TAHOD n = 2521) were included; 910 (18%) of patients experienced blips. 744 (21%) and 166 (11%) of high- and middle/low-income participants, respectively, experienced blips ever. 711 (14%) experienced blips prior to virological failure. 559 (16%) and 152 (10%) of high- and middle/low-income participants, respectively, experienced blips prior to virological failure. VL testing occurred at a median frequency of 175 and 91 days in middle/low- and high-income sites, respectively. Longer time to VF occurred in middle/low income sites, compared with high-income sites (adjusted hazards ratio (AHR) 0.41; p<0.001), adjusted for year of first cART, Hepatitis C co-infection, cART regimen, and prior blips. Prior blips were not a significant predictor of VF in univariate analysis (AHR 0.97, p = 0.82). Differing magnitudes of blips were not significant in univariate analyses as predictors of virological failure (p = 0.360 for blip 50–≤1000, p = 0.309 for blip 50–≤400 and p = 0.300 for blip 50–≤200). 209 of 866 (24%) patients were switched to an alternate regimen in the setting of a blip. Conclusion Despite a lower proportion of blips occurring in low/middle-income settings, no significant difference was found between settings. Nonetheless, a

    The extensive use of electronic health data has increased privacy concerns. While most healthcare organizations are conscientious in protecting their data in their databases, very few organizations take enough precautions to protect data that is shared with third party organizations. Recently the regulatory environment has tightened the laws to enforce privacy protection. The goal of this research is to explore the application of data masking solutions for protecting patient privacy when data is shared with external organizations for research, analysis and other similar purposes. Specifically, this research project develops a system that protects data without removing sensitive attributes. Our application allows high quality data analysis with the masked data. Dataset-level properties and statistics remain approximately the same after data masking; however, individual record-level values are altered to prevent privacy disclosure. A pilot evaluation study on large real-world healthcare data shows the effectiveness of our solution in privacy protection. PMID:24285983

    Variations in the performance of healthcare organizations may be partly explained by differing "stocks" of intellectual capital (IC), and differing approaches and capacities for leveraging IC. This study synthesizes what is currently known about the conceptualization, management and measurement of IC in healthcare through a review of the literature. Peer-reviewed papers on IC in healthcare published between 1990 and 2014 were identified through searches of five databases using the following key terms: intellectual capital/assets, knowledge capital/assets/resources, and intangible assets/resources. Articles deemed relevant for inclusion underwent systematic data extraction to identify overarching themes and were assessed for their methodological quality. Thirty-seven papers were included in the review. The primary research method used was cross-sectional questionnaires focused on hospital managers' perceptions of IC, followed by semi-structured interviews and analysis of administrative data. Empirical studies suggest that IC is linked to subjective process and performance indicators in healthcare organizations. Although the literature on IC in healthcare is growing, it is not advanced. In this paper, we identify and examine the conceptual, theoretical and methodological limitations of the literature. The concept and framework of IC offer a means to study the value of intangible resources in healthcare organizations, how to manage systematically these resources together, and their mutually enhancing interactions on performance. We offer several recommendations for future research.

    As information & communication technologies have advanced, interest in mobile health care systems has grown. In order to obtain information seamlessly from distributed and fragmented clinical data from heterogeneous institutions, we need solutions that integrate data. In this article, we introduce a method for information integration based on real-time message communication using trigger and advanced database technologies. Messages were devised to conform to HL7, a standard for electronic data exchange in healthcare environments. The HL7 based system provides us with an integrated environment in which we are able to manage the complexities of medical data. We developed this message communication interface to generate and parse HL7 messages automatically from the database point of view. We discuss how easily real time data exchange is performed in the clinical information system, given the requirement for minimum loading of the database system. PMID:14728271

    Provider organizations lack: 1. a definition of "virtual" healthcare delivery relative to the products, services, and processes offered by dot.coms, web-compact disk healthcare content providers, telemedicine, and telecommunications companies, and 2. a model for integrating real and virtual healthcare delivery. This paper defines virtual healthcare delivery as asynchronous, outsourced, and anonymous, then proposes a 2x2 Real-Virtual Healthcare Delivery model focused on real and virtual patients and real and virtual provider organizations. Using this model, provider organizations can systematically deconstruct healthcare delivery in the real world and reconstruct appropriate pieces in the virtual world. Observed barriers to virtual healthcare delivery are: resistance to telecommunication integrated delivery networks and outsourcing; confusion over virtual infrastructure requirements for telemedicine and full-service web portals, and the impact of integrated delivery networks and outsourcing on extant cultural norms and revenue generating practices. To remain competitive provider organizations must integrate real and virtual healthcare delivery.

    There is a large data bank of positional observations of Solar System bodies at Engelhadt Astronomical Observatory (EAO). The positional observations include the major planets, except Jupiter. Modern technologies replace classical methods of observations in astronomy and in astrometry as well. At the same time many positional observations have been gathered at astronomical observatories. So taking into account that observations of the past epochs have presenteda great value for astronomy and as times goes by their importance is growing it is obvious that positional astrometry will not lose its practical importance. This was noted in B3 XXIV IAU resolution by the General Assembly. The results of reduction of solar system bodies observations were published mainly in Proceeding of EAO and Transactions of Kazan City Astronomical Observatory. Earlier there have been made about three thousand observations at EAO and Zelenchuk station with the Zeiss telescope (D=400mm, f=2000mm), AFR-18 (photo visual, D=200, f=2000), refractor (D=400mm, f=3450mm), Meniscus camera (D=340mm, f=1200mm), Schmidt camera (D=350mm, f=2000mm). The major planets except Pluto and Neptune were observed with a special cassette chamber equipped with a rotating disk which had an open sector to reduce the brightness of the planets. The dimension of the sector was chosen accordingto the brightness of the planets. The disk was placed in the centre of the astrograph's field. The stars' true brightness was preserved. A large number of catalogues were compiled by the end of the 20th century. We used Tycho-2 catalogue for reducing our observations. As it is known the catalogue Tycho-2 (Tycho-2 catalogue, 2000) includes 2539913 stars. The stars' proper motions given in the catalogue were obtained by comparing positions from Tycho-2 with positions from the Astrographic Catalogue. Therefore they are considered to be highly accurate. The accuracy of stellar positions in Tycho-2 is about 60 mas and the accuracy of

    To estimate the costs of healthcare resource consumption in the year preceding and the year following a myocardial infarction (MI). A historical cohort of patients experiencing an MI in France between 2007 and 2011 was extracted from the échantillon généraliste de bénéficiaires, a 1/97th sample of all beneficiaries of public health insurance in France. A total of 1920 patients experiencing an MI were identified. Two-thirds were men and the mean age was 67 years; 20.6% had diabetes, 37.6% hypercholesterolaemia and 82.4% hypertension. From a societal perspective, the annual costs of medical consumption related to hospitalisations increased from € 4548 before the MI to € 6470 in the following year. Costs of community care rose from € 2932 to € 6208. This increase concerned all components of community healthcare: costs associated with medical transportation increased fourfold, those associated with consultations and laboratory tests tripled, medication costs doubled and costs of paramedical services also increased, but to a lesser extent. It should be noted that the cost of hospitalisation for the index MI (€ 5876) is not included in the above costs. From a society perspective, the cost of healthcare resource consumption increased threefold in the year following an MI. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Patients with multiple myeloma (MM) often experience debilitating skeletal-related events (SREs: pathologic fracture, radiation to bone [RB], surgery to bone [SB] or spinal cord compression [SCC]). This is the first comprehensive, prospective, observational analysis of healthcare resource utilisation (HRU), independently attributed to SREs by investigators, in patients with MM. Eligible patients had lytic bone lesions, life expectancy ≥6 months, Eastern Cooperative Oncology Group performance status ≤2 and ≥1 SRE in the 97 days before enrolment. Data were collected retrospectively for 97 days before enrolment and prospectively for 18-21 months. Altogether, 153 patients were enrolled from Germany, Italy, Spain and the United Kingdom. Of the 281 observed SREs, 36.7% required inpatient stays (mean duration: 20.6 days per SRE [standard deviation (SD): 22.9]). SB and SCC were the SREs most likely to require stays (72.3% and 50.0% of SREs, respectively); SCC required the longest mean (SD) stay per event (40.5 [40.8] days). Overall, 179 SREs required outpatient visits; this was most likely for RB (74.8%) and least likely for non-vertebral fracture (50.0%). All SREs were associated with substantial HRU; therefore, preventing SREs in MM will reduce the economic and resource burden on healthcare systems. © 2018 The Authors.

    Objective The aim was to study gender differences in care-seeking behavior and treatment provided immediately after whiplash trauma. Methods Participants were residents from a defined geographical area, Skaraborg County in the southwestern part of Sweden. A cohort of 3,368 persons exposed to whiplash trauma and attending a healthcare facility immediately after the trauma between 1999 and 2008 were identified in a database. Information about gender, age, time elapsed prior to seeking care, type of healthcare contact, initial treatment provided and eventual hospitalization time was retrieved. Results Women sought care later than men (p = 0.00074). Women consulted primary healthcare first more often than men, who more often first sought hospital care (p = 0.0060). There were no gender differences regarding the type of treatment after trauma. Women had longer hospital admission than men (p = 0.022), indicating their injuries were at least similar to or worse than men’s. Conclusion Women sought healthcare later than men after whiplash trauma. Although not directly investigated in this study, it raises the question if this may reduce their probability of getting financial compensation compared to men. PMID:28441465

    2018-01-01

    Healthcare directories are vital for interoperability among healthcare providers, researchers and patients. Past efforts at directory services have not provided the tools to allow integration of the diverse data sources. Many are overly strict, incompatible with legacy databases, and do not provide Data Provenance. A more architecture-independent system is needed to enable secure, GDPR-compatible (8) service discovery across organizational boundaries. We review our development of a portable Data Provenance Toolkit supporting provenance within Health Information Exchange (HIE) systems. The Toolkit has been integrated with client software and successfully leveraged in clinical data integration. The Toolkit validates provenance stored in a Blockchain or Directory record and creates provenance signatures, providing standardized provenance that moves with the data. This healthcare directory suite implements discovery of healthcare data by HIE and EHR systems via FHIR. Shortcomings of past directory efforts include the ability to map complex datasets and enabling interoperability via exchange endpoint discovery. By delivering data without dictating how it is stored we improve exchange and facilitate discovery on a multi-national level through open source, fully interoperable tools. With the development of Data Provenance resources we enhance exchange and improve security and usability throughout the health data continuum.

    2007-01-01

    Introduction This document describes the data fields that are used for both field forms and the Ethiopian National Ground-water Database (ENGDA) tables associated with information stored about production wells, springs, test holes, test wells, and water level or water-quality observation wells. Several different words are used in this database dictionary and in the ENGDA database to describe a narrow shaft constructed in the ground. The most general term is borehole, which is applicable to any type of hole. A well is a borehole specifically constructed to extract water from the ground; however, for this data dictionary and for the ENGDA database, the words well and borehole are used interchangeably. A production well is defined as any well used for water supply and includes hand-dug wells, small-diameter bored wells equipped with hand pumps, or large-diameter bored wells equipped with large-capacity motorized pumps. Test holes are borings made to collect information about the subsurface with continuous core or non-continuous core and/or where geophysical logs are collected. Test holes are not converted into wells. A test well is a well constructed for hydraulic testing of an aquifer in order to plan a larger ground-water production system. A water-level or water-quality observation well is a well that is used to collect information about an aquifer and not used for water supply. A spring is any naturally flowing, local, ground-water discharge site. The database dictionary is designed to help define all fields on both field data collection forms (provided in attachment 2 of this report) and for the ENGDA software screen entry forms (described in Litke, 2007). The data entered into each screen entry field are stored in relational database tables within the computer database. The organization of the database dictionary is designed based on field data collection and the field forms, because this is what the majority of people will use. After each field, however, the

    2015-09-01

    In 2010, diabetes was the seventh leading cause of death in the United States. Diabetes also imposes a huge financial burden on the US economy. In 2009, the American Diabetes Association International Expert Committee recommended the use of the glycated hemoglobin (HbA1c) test as a uniform diagnostic measure to identify patients with diabetes. Although HbA1c is a convenient diagnostic test, it is also more expensive than older tests and could, therefore, have an impact on patients' healthcare expenditures. To determine if HbA1c testing has an impact on total annual healthcare expenditures among newly diagnosed patients with diabetes and to analyze the factors that are associated with the total healthcare expenditures among diabetic patients before and after HbA1c was implemented as a standard diagnostic factor. This was an observational, retrospective, cross-sectional study. The Medical Expenditure Panel Survey-Household Component 2009 and 2011 databases were used to form the study cohort of patients with diabetes. The total mean healthcare expenditures among patients with diabetes formed the dependent variable. A proxy variable representing a diagnosis of diabetes with and without the use of HbA1c testing in 2009 and in 2011, respectively, formed the main independent variable along with demographic factors, comorbidities, and healthcare services utilization in both years. A generalized linear regression was conducted to determine the association of HbA1c testing with total diabetes-related healthcare expenditures. The mean total healthcare expenditure decreased in 2011 compared with 2009. The HbA1c test did not show an association with the total healthcare expenditures versus earlier diabetes-related diagnostic factors. The total expenditures were associated with private insurance, the incidence of a previous heart attack, prescription drug refills, inpatient hospital stays, home care, hospital discharges, and visits to outpatient providers and physicians in both

    This review considers current trauma scoring systems and databases and their relevance to improving patient care. Single physiological measures such as systolic arterial pressure have limited ability to diagnose severe trauma by reflecting raised intracranial pressure, or significant haemorrhage. The Glasgow coma score has the greatest prognostic value in head-injured and other trauma patients. Trauma triage tools and imaging decision rules-using combinations of physiological cut-off measures with mechanism of injury and other categorical variables-bring both increased sophistication and increased complexity. It is important for clinicians and managers to be aware of the diagnostic properties (over- and under-triage rates) of any triage tool or decision rule used in their trauma system. Trauma registries are able to collate definitive injury descriptors and use survival prediction models to guide trauma system governance, through individual patient review and case-mix-adjusted benchmarking of hospital and network performance with robust outlier identification. Interrupted time series allow observation in the changes in care processes and outcomes at national level, which can feed back into clinical quality-based commissioning of healthcare. Registry data are also a valuable resource for trauma epidemiological and comparative effectiveness research studies. © The Author 2014.

    The use of multiuser virtual worlds (MUVWs) for collaborative learning has generated interest among healthcare educators. Published evidence to support its use is growing, but none has synthesized the evidence to guide future work. This study sought to provide a comprehensive and systematic evaluation of MUVWs in healthcare education. A systematic review METHODS: A systematic search of five databases including CINAHL, Cochrane library, EMBASE, PubMed, and Scopus, was conducted from inception up to January 2017. Two independent researchers selected studies that met the inclusion criteria and assessed for methodological quality using the Medical Education Research Study Quality Instrument (MERSQI). A total of 18 studies were reviewed and their data were synthesized narratively using a 3-P model (presage-process-product). Average scores in the MERSQI for methodological quality are 10/18, which is modest. A rally by the government or professional bodies towards more collaborative working among healthcare professionals is a key driver behind implementing MUVWs. Funding is important for its development and evaluation. Team training in acute care and communication training were the most frequent learning objectives, and predominant learning activities include practice on simulation scenario and debriefing. Two-thirds of the studies did not explain their theoretical framework that underpinned their design and implementation of MUVWs. While MUVWs in healthcare education is generally well-received, learning outcomes remain inconclusive. Despite a growth of studies on the use of MUVW in healthcare education, there is a need for more understanding of the application of theories to inform the learning activities. Therefore, we suggest educators to incorporate a theoretical model to explain the learning processes behind MUVWs. To improve the quality of evidence, we call for researchers to employ a more rigorous and broader approach to evaluation that explicates longer

    administrative healthcare data are among main components of hospital information system. Such data can be analyzed and deployed for a variety of purposes. The principal aim of this research was to depict trends of administrative healthcare data from HIS in a general hospital from March 2011 to March 2014. data set used for this research was extracted from the SQL database of the hospital information system in Razi general hospital located in Marand. The data were saved as CSV (Comma Separated Values) in order to facilitate data cleaning and analysis. The variables of data set included patient's age, gender, final diagnosis, final diagnosis code based on ICD-10 classification system, date of hospitalization, date of discharge, LOS(Length of Stay), ward, and survival status of the patient. Data were analyzed and visualized after applying appropriate cleansing and preparing techniques. morbidity showed a constant trend over three years. Pregnancy, childbirth and the puerperium were the leading category of final diagnosis (about 32.8 %). The diseases of the circulatory system were the second class accounting for 13 percent of the hospitalization cases. The diseases of the digestive system had the third rank (10%). Patients aged between 14 and 44 constituted a higher proportion of total cases. Diseases of the circulatory system was the most common class of diseases among elderly patients (age≥65). The highest rate of mortality was observed among patients with final diagnosis of the circulatory system diseases followed by those with diseases of the respiratory system, and neoplasms. Mortality rate for the ICU and the CCU patients were 62% and 33% respectively. The longest average of LOS (7.3 days) was observed among patients hospitalized in the ICU while patients in the Obstetrics and Gynecology ward had the shortest average of LOS (2.4 days). Multiple regression analysis revealed that LOS was correlated with variables of surgery, gender, and type of payment, ward, the

    The age of diagnosis of congenital hearing loss is one of the most important determinants of communication outcome. A previous study by the lead author had evaluated the performance of the public health services in Bloemfontein, South Africa (SA), in this regard. This study aimed to examine whether the private health services in the same city were any better. To determine whether the age of diagnosis of congenital hearing loss (CHL) in children seen in the private healthcare sector in Bloemfontein, Free State Province, SA, was lower than that in the public healthcare system in the same city. A comparative study design was utilised and a retrospective database review conducted. Data obtained from this study in the private healthcare sector were compared with data from a previous study in the public healthcare sector using the same study design. Forty-eight children aged <6 years with disabling hearing impairment (DHI) were identified in the private healthcare sector during the study period; 33/47 (70.2%) did not undergo hearing screening at birth. The median age of diagnosis of DHI in the private healthcare sector was 2.24 years, and this was statistically significantly lower than the median age of diagnosis of 3.71 years in the public healthcare sector (p<0.0001; 95% confidence interval (CI) 0.99-2.0). The median age of diagnosis of congenital hearing loss (CHL) in the private healthcare sector was 3.01 years in children who were not screened at birth, and 1.25 years in those who were screened at birth. This difference was statistically significant (p<0.01; 95% CI 0.72-2.47). We also compared the median age of diagnosis of CHL in children from the private healthcare sector who were not screened at birth (median 3.01 years) with that in children in the public healthcare sector (median 3.71 years). This difference was statistically significant (p<0.01; 95% CI 0.41-1.56). Children in the Free State are diagnosed with CHL at a younger age in the private healthcare

    In this paper we suggest that the healthcare enterprise needs to be more conscious of its vast knowledge resources vis-à-vis the exploitation of knowledge management techniques to efficiently manage its knowledge. The development of healthcare enterprise memory is suggested as a solution, together with a novel approach advocating the operationalisation of healthcare enterprise memories leading to the modelling of healthcare processes for strategic planning. As an example, we present a simulation of Service Delivery Time in a hospital's OPD.

    We assessed safe injection practices among 1100 health-care workers in 25 health-care facilities in Gharbiya Governorate. Questionnaires were used to collect information and 278 injections were observed using a standardized checklist. There was a lack of infection control policies in all the facilities and a lack of many supplies needed for safe injection. Proper needle manipulation before disposal was observed in only 41% of injections, safe needle disposal in 47.5% and safe syringe disposal in 0%. Reuse of used syringes and needles was reported by 13.2% of the health-care workers and 66.2% had experienced a needle-stick injury. Only 11.3% had received a full course of hepatitis B vaccination.

    The ethics and value bases in healthcare are widely acknowledged. There is a need to improve and raise awareness of ethics in complex systems and in line with competing needs, different stakeholders and patients' rights. Evidence-based strategies and interventions for the development of procedures and practice have been used to improve care and services. However, it is not known whether and to what extent ethics can be developed using interventions. To examine ethics interventions conducted on healthcare professionals and healthcare students to achieve ethics-related outcomes. A systematic review. Five electronic databases were searched: CINAHL, the Cochrane Library, Philosopher's Index, PubMed and PsycINFO. We searched for published articles written in English without a time limit using the keywords: ethic* OR moral* AND intervention OR program OR pre-post OR quasi-experimental OR rct OR experimental AND nurse OR nursing OR health care. In the four-phased retrieval process, 23 full texts out of 4675 citations were included in the review. Data were analysed using conventional content analysis. Ethical consideration: This systematic review was conducted following good scientific practice in every phase. It is possible to affect the ethics of healthcare practices through professionals and students. All the interventions were educational in type. Many of the interventions were related to the ethical or moral sensitivity of the professionals, such as moral courage and empowerment. A few of the interventions focused on identifying ethical problems or research ethics. Patient-related outcomes followed by organisational outcomes can be improved by ethics interventions targeting professionals. Such outcomes are promising in developing ethical safety for healthcare patients and professionals.

    To identify all published nutritional screening instruments that have been validated in the adult population in primary healthcare settings and to report on their psychometric validity. Within health care, there is an urgent need for the systematic collection of nursing care data in order to make visible what nurses do and to facilitate comparison, quality assurance, management, research and funding of nursing care. To be effective, nursing records should accurately and comprehensively document all required information to support safe and high quality care of patients. However, this process of documentation has been criticized from many perspectives as being highly inadequate. A Nursing Minimum Data Set within the nutritional area in primary health care could therefore be beneficial in order to support nurses in their daily documentation and observation of patients. The review considered studies that included adults aged over 18 years of any gender, culture, diagnosis and ethnicity, as well as nutritional experts, patients and their relatives. The concepts of interest were: the nature and content of any nutritional screening tools validated (regardless of the type of validation) in the adult population in primary healthcare; and the views and opinions of eligible participants regarding the appropriateness of nutritional assessment were the concept of interest. Studies included must have been conducted in primary healthcare settings, both within home care and nursing home facilities. This scoping review used a two-step approach as a preliminary step to the subsequent development of a Nursing Minimum Data Set within the nutritional area in primary healthcare: i) a systematic literature search of existing nutritional screening tools validated in primary health care; and ii) a systematic literature search on nutritional experts opinions on the assessment of nutritional nursing care of adults in primary healthcare as well as the views of patients and their relatives

    Numerous studies have shown that healthcare professionals are exposed to psychological distress. However, since most of these studies assessed psychological distress using self-reporting questionnaires, the magnitude of the problem is largely unknown. We evaluated the risks of mood disorders, anxiety disorders, sleep disorders, and any psychiatric disorders in workers in healthcare industry using Korea National Health Insurance (NHI) claims data from 2014, which are based on actual diagnoses instead of self-evaluation. We used Korea 2014 NHI claims data and classified employees as workers in the healthcare industry, based on companies in the NHI database that were registered with hospitals, clinics, public healthcare, and other medical services. To estimate the standardized prevalence of the selected mental health disorders, we calculated the prevalence of diseases in each age group and sex using the age distribution of the Korea population. To compare the risk of selected mental disorders among workers in the healthcare industry with those in other industries, we considered age, sex, and income quartile characteristics and conducted propensity scored matching. In the matching study, workers in healthcare industry had higher odds ratios for mood disorders (1.13, 95% CI: 1.11-1.15), anxiety disorders (1.15, 95% CI: 1.13-1.17), sleep disorders (2.21, 95% CI: 2.18-2.24), and any psychiatric disorders (1.44, 95% CI: 1.43-1.46) than the reference group did. Among workers in healthcare industry, females had higher prevalence of psychiatric disorders than males, but the odds ratios for psychiatric disorders, compared to the reference group, were higher in male workers in healthcare industry than in females. The prevalence of mood disorders, anxiety disorders, sleep disorders, and all psychiatric disorders for workers in the healthcare industry was higher than that of other Korean workers. The strikingly high prevalence of sleep disorders could be related to the frequent

    We develop a theoretical model of a local healthcare system in which consumers, health insurance companies, and healthcare providers interact with each other in markets for health insurance and healthcare services. When income and health status are heterogeneous, and healthcare quality is associated with fixed costs, the market equilibrium level of healthcare quality will be underprovided. Thus, healthcare reform provisions and proposals to cover the uninsured can be interpreted as an attempt to correct this market failure. We illustrate with a numerical example that if consumers at the local level clearly understand the linkages between health insurance coverage and the quality of local healthcare services, health insurance coverage proposals are more likely to enjoy public support.

    Electronic health records (EHR) contain a large amount of structured data and free text. Exploring and sharing clinical data can improve healthcare and facilitate the development of medical software. However, revealing confidential information is against ethical principles and laws. We de-identified a Danish EHR database with 437,164 patients. The goal was to generate a version with real medical records, but related to artificial persons. We developed a de-identification algorithm that uses lists of named entities, simple language analysis, and special rules. Our algorithm consists of 3 steps: collect lists of identifiers from the database and external resources, define a replacement for each identifier, and replace identifiers in structured data and free text. Some patient records could not be safely de-identified, so the de-identified database has 323,122 patient records with an acceptable degree of anonymity, readability and correctness (F-measure of 95%). The algorithm has to be adjusted for each culture, language and database.

A comprehensive suite of ozone data products including standard statistics, health and vegetation impact metrics, and trend information, are made available through a common data portal and a web interface. These data form the basis of the TOAR analyses focusing on human health, vegetation, and climate relevant ozone issues, which are part of this special feature. Cooperation among many data centers and individual researchers worldwide made it possible to buildmore » the world's largest collection of in-situ hourly surface ozone data covering the period from 1970 to 2015. By combining the data from almost 10,000 measurement sites around the world with global metadata information, new analyses of surface ozone have become possible, such as the first globally consistent characterisations of measurement sites as either urban or rural/remote. Exploitation of these global metadata allows for new insights into the global distribution, and seasonal and long-term changes of tropospheric ozone and they enable TOAR to perform the first, globally consistent analysis of present-day ozone concentrations and recent ozone changes with relevance to health, agriculture, and climate. Considerable effort was made to harmonize and synthesize data formats and metadata information from various networks and individual data submissions. Extensive quality control was applied to identify questionable and erroneous data, including changes in apparent instrument offsets or calibrations. Such data were excluded from TOAR data products. Limitations of a posteriori data quality assurance are discussed. As a result of the work presented here, global coverage of surface ozone data for scientific analysis has been significantly extended. Yet, large gaps remain in the surface observation

    This paper aims to provide evidence of the healthcare needs of prisoners in relation to gender, age and ethnicity, drawing from a larger systematic overview of the policy and research literature concerning primary care nursing in prisons in England and Wales. The literature overview shaped the initial stages of a research project funded by the Department of Health to examine the views and perspectives of prisoners and nurses working in prisons, and to identify good primary care nursing in the prison environment. At total of 17 databases were searched using search terms related to primary healthcare in prisons (health, nurs*, primary care, healthcare, family medicine, prison*, offender*, inmate*) with terms truncated where possible in the different databases. Following this, a sifting phase was employed using inclusion/exclusion criteria to narrow and focus the literature perceived as relevant to the research questions. All papers were critically appraised for quality using standardised tools. Findings from the literature overview show that prisoners are more likely to have suffered some form of social exclusion compared to the rest of society, and there are significantly greater degrees of mental health problems, substance abuse and worse physical health in prisoners than in the general population. Women, young offenders, older prisoners and those from minority ethnic groups have distinct health needs compared to the prison population taken as a whole, with implications for the delivery of prison healthcare, and how these needs are met effectively and appropriately.

    Of the 4.8 million uninsured children in America, 62-72% are eligible for but not enrolled in Medicaid or CHIP. Not enough is known, however, about the impact of health insurance on outcomes and costs for previously uninsured children, which has never been examined prospectively. This prospective observational study of uninsured Medicaid/CHIP-eligible minority children compared children obtaining coverage vs. those remaining uninsured. Subjects were recruited at 97 community sites, and 11 outcomes monitored monthly for 1 year. In this sample of 237 children, those obtaining coverage were significantly (P < .05) less likely than the uninsured to have suboptimal health (27% vs. 46%); no PCP (7% vs. 40%); experienced never/sometimes getting immediate care from the PCP (7% vs. 40%); no usual source of preventive (1% vs. 20%) or sick (3% vs. 12%) care; and unmet medical (13% vs. 48%), preventive (6% vs. 50%), and dental (18% vs. 62%) care needs. The uninsured had higher out-of-pocket doctor-visit costs (mean = $70 vs. $29), and proportions of parents not recommending the child's healthcare provider to friends (24% vs. 8%) and reporting the child's health caused family financial problems (29% vs. 5%), and lower well-child-care-visit quality ratings. In bivariate analyses, older age, birth outside of the US, and lacking health insurance for >6 months at baseline were associated with remaining uninsured for the entire year. In multivariable analysis, children who had been uninsured for >6 months at baseline (odds ratio [OR], 3.8; 95% confidence interval [CI], 1.4-10.3) and African-American children (OR, 2.8; 95% CI, 1.1-7.3) had significantly higher odds of remaining uninsured for the entire year. Insurance saved $2886/insured child/year, with mean healthcare costs = $5155/uninsured vs. $2269/insured child (P = .04). Providing health insurance to Medicaid/CHIP-eligible uninsured children improves health, healthcare access and quality, and parental satisfaction

    This literature review identifies and categorises, from an organisational management perspective, barriers to the use of HIT or ICT for health. Based on the review, it offers policy interventions. This systematic literature review was carried out during December 2009 and January 2010. Additional on-going reviews of updates through automated system alerts took place up until this paper was submitted. A total of thirty-one sources were searched including nine software platforms/databases, fifteen specialised websites/targeted databases, Google Scholar, ISI Science Citation Index and five journals hand-searched. The study covers seventy-nine articles on organisational barriers to ICT adoption by healthcare professionals. These are categorised under five main headings - (I) Structure of healthcare organisations; (II) Tasks; (III) People policies; (IV) Incentives; and (V) Information and decision processes. A total of ten subcategories are also identified. By adopting an organisational management approach, some recommendations to remove organisational management barriers are made. Despite their apparent promise, health information technologies (HIT) have proved difficult to implement. This systematic review reveals the implementation barriers associated to organisational management and their interrelations. Several important future directions in the field are also suggested: (1) there is a need for further research providing evidence of HIT cost-effectiveness as well as the development of optimal HIT applications; (2) more information is needed regarding organisational change, incentives, liability issues, end-users HIT competences and skills, structure and work process issues involved in realising the benefits from HIT. Future policy interventions should consider the five dimensions identified when addressing the impact of HIT in healthcare organisational systems, and how the impact of an intervention aimed at a particular dimension would interrelate with others. 2011

    Healthcare data are a valuable source of healthcare intelligence. Sharing of healthcare data is one essential step to make healthcare system smarter and improve the quality of healthcare service. Healthcare data, one personal asset of patient, should be owned and controlled by patient, instead of being scattered in different healthcare systems, which prevents data sharing and puts patient privacy at risks. Blockchain is demonstrated in the financial field that trusted, auditable computing is possible using a decentralized network of peers accompanied by a public ledger. In this paper, we proposed an App (called Healthcare Data Gateway (HGD)) architecture based on blockchain to enable patient to own, control and share their own data easily and securely without violating privacy, which provides a new potential way to improve the intelligence of healthcare systems while keeping patient data private. Our proposed purpose-centric access model ensures patient own and control their healthcare data; simple unified Indicator-Centric Schema (ICS) makes it possible to organize all kinds of personal healthcare data practically and easily. We also point out that MPC (Secure Multi-Party Computing) is one promising solution to enable untrusted third-party to conduct computation over patient data without violating privacy.

    As the US transitions to value-based healthcare, physicians and payers are incentivized to change healthcare delivery to improve quality of care while controlling costs. By assisting with the management of common chronic conditions, community health workers (CHWs) may improve healthcare quality, but physicians and payers who are making choices about care delivery also need to understand their effects on healthcare spending. We searched PubMed, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, PsycINFO, Embase, and Web of Science from the inception of each database to 22 June 2015. We included US-based studies that evaluated a CHW intervention for patients with at least one chronic health condition and reported cost or healthcare utilization outcomes. We evaluated studies using tools specific to study design. Our search yielded 2,941 studies after removing duplicates. Thirty-four met inclusion and methodological criteria. Sixteen studies (47%) were randomized controlled trials (RCTs). RCTs typically had less positive outcomes than other study designs. Of the 16 RCTs, 12 reported utilization outcomes, of which 5 showed a significant reduction in one or more of ED visits, hospitalizations and/or urgent care visits. Significant reductions reported in ED visits ranged from 23%-51% and in hospitalizations ranged from 21%-50%, and the one significant reduction in urgent care visits was recorded at 60% (p < 0.05 for all). Our results suggest that CHW interventions have variable effects, but some may reduce costs and preventable utilization. These findings suggest that it is possible to achieve reductions in care utilization and cost savings by integrating CHWs into chronic care management. However, variations in cost and utilization outcomes suggest that CHWs alone do not make an intervention successful. The paucity of rigorous studies and heterogeneity of study designs limited conclusions about factors associated with reduced

    The EXOSAT database provides on-line access to the results and data products (spectra, images, and lightcurves) from the EXOSAT mission as well as access to data and logs from a number of other missions (such as EINSTEIN, COS-B, ROSAT, and IRAS). In addition, a number of familiar optical, infrared, and x ray catalogs, including the Hubble Space Telescope (HST) guide star catalog are available. The complete database is located at the EXOSAT observatory at ESTEC in the Netherlands and is accessible remotely via a captive account. The database management system was specifically developed to efficiently access the database and to allow the user to perform statistical studies on large samples of astronomical objects as well as to retrieve scientific and bibliographic information on single sources. The system was designed to be mission independent and includes timing, image processing, and spectral analysis packages as well as software to allow the easy transfer of analysis results and products to the user's own institute. The archive at ESTEC comprises a subset of the EXOSAT observations, stored on magnetic tape. Observations of particular interest were copied in compressed format to an optical jukebox, allowing users to retrieve and analyze selected raw data entirely from their terminals. Such analysis may be necessary if the user's needs are not accommodated by the products contained in the database (in terms of time resolution, spectral range, and the finesse of the background subtraction, for instance). Long-term archiving of the full final observation data is taking place at ESRIN in Italy as part of the ESIS program, again using optical media, and ESRIN have now assumed responsibility for distributing the data to the community. Tests showed that raw observational data (typically several tens of megabytes for a single target) can be transferred via the existing networks in reasonable time.

    Various dimensions of healthcare service quality were used and discussed in literature across the globe. This study presents an updated meaningful review of the extensive research that has been conducted on measuring dimensions of healthcare service quality. Systematic review method in current study is based on PRISMA guidelines. We searched for literature using databases such as Google, Google Scholar, PubMed and Social Science, Citation Index. In this study, we screened 1921 identified papers using search terms/phrases. Snowball strategies were adopted to extract published articles from January 1997 till December 2016. Two-hundred and fourteen papers were identified as relevant for data extraction; completed by two researchers, double checked by the other two to develop agreement in discrepancies. In total, 74 studies fulfilled our pre-defined inclusion and exclusion criteria for data analysis. Service quality is mainly measured as technical and functional, incorporating many sub-dimensions. We synthesized the information about dimensions of healthcare service quality with reference to developed and developing countries. 'Tangibility' is found to be the most common contributing factor whereas 'SERVQUAL' as the most commonly used model to measure healthcare service quality. There are core dimensions of healthcare service quality that are commonly found in all models used in current reviewed studies. We found a little difference in these core dimensions while focusing dimensions in both developed and developing countries, as mostly SERVQUAL is being used as the basic model to either generate a new one or to add further contextual dimensions. The current study ranked the contributing factors based on their frequency in literature. Based on these priorities, if factors are addressed irrespective of any context, may lead to contribute to improve healthcare quality and may provide an important information for evidence-informed decision-making.

    IAGOS (In-service Aircraft for a Global Observing System) is a European Research Infrastructure which aims at the provision of long-term, regular and spatially resolved in situ observations of the atmospheric composition. IAGOS observation systems are deployed on a fleet of commercial aircraft. The IAGOS database is an essential part of the global atmospheric monitoring network. It contains IAGOS-core data and IAGOS-CARIBIC (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) data. The IAGOS Database Portal (http://www.iagos.fr, damien.boulanger@obs-mip.fr) is part of the French atmospheric chemistry data center AERIS (http://www.aeris-data.fr). The new IAGOS Database Portal has been released in December 2015. The main improvement is the interoperability implementation with international portals or other databases in order to improve IAGOS data discovery. In the frame of the IGAS project (IAGOS for the Copernicus Atmospheric Service), a data network has been setup. It is composed of three data centers: the IAGOS database in Toulouse; the HALO research aircraft database at DLR (https://halo-db.pa.op.dlr.de); and the CAMS data center in Jülich (http://join.iek.fz-juelich.de). The CAMS (Copernicus Atmospheric Monitoring Service) project is a prominent user of the IGAS data network. The new portal provides improved and new services such as the download in NetCDF or NASA Ames formats, plotting tools (maps, time series, vertical profiles, etc.) and user management. Added value products are available on the portal: back trajectories, origin of air masses, co-location with satellite data, etc. The link with the CAMS data center, through JOIN (Jülich OWS Interface), allows to combine model outputs with IAGOS data for inter-comparison. Finally IAGOS metadata has been standardized (ISO 19115) and now provides complete information about data traceability and quality.

    The objective of the study was to conduct a within-cohort assessment of risk factors for incident AIDS-defining cancers (ADCs) and non-ADCs (NADCs) within the Australian HIV Observational Database (AHOD). A total of 2181 AHOD registrants were linked to the National AIDS Registry/National HIV Database (NAR/NHD) and the Australian Cancer Registry to identify those with a notified cancer diagnosis. Included in the current analyses were cancers diagnosed after HIV infection. Risk factors for cancers were also assessed using logistic regression methods. One hundred and thirty-nine cancer cases were diagnosed after HIV infection among 129 patients. More than half the diagnoses (n = 68; 60%) were ADCs, of which 69% were Kaposi's sarcoma and 31% non-Hodgkin's lymphoma. Among the NADCs, the most common cancers were melanoma (n = 10), lung cancer (n = 6), Hodgkin's lymphoma (n = 5) and anal cancer (n = 5). Over a total of 21021 person-years (PY) of follow-up since HIV diagnosis, the overall crude cancer incidence rate for any cancer was 5.09/1000 PY. The overall rate of cancers decreased from 15.9/1000 PY [95% confidence interval (CI) 9.25-25.40/1000 PY] for CD4 counts < 100 cells/μL to 2.4/1000 PY (95% CI 1.62-3.39/1000 PY) for CD4 counts > 350 cells/μL. Lower CD4 cell count and prior AIDS diagnoses were significant predictors for both ADCs and NADCs. ADCs remain the predominant cancers in this population, although NADC rates have increased in the more recent time period. Immune deficiency is a risk factor for both ADCs and NADCs. © 2012 British HIV Association.

  9. Factors influencing healthcare service quality

    Background: The main purpose of this study was to identify factors that influence healthcare quality in the Iranian context. Methods: Exploratory in-depth individual and focus group interviews were conducted with 222 healthcare stakeholders including healthcare providers, managers, policy-makers, and payers to identify factors affecting the quality of healthcare services provided in Iranian healthcare organisations. Results: Quality in healthcare is a production of cooperation between the patient and the healthcare provider in a supportive environment. Personal factors of the provider and the patient, and factors pertaining to the healthcare organisation, healthcare system, and the broader environment affect healthcare service quality. Healthcare quality can be improved by supportive visionary leadership, proper planning, education and training, availability of resources, effective management of resources, employees and processes, and collaboration and cooperation among providers. Conclusion: This article contributes to healthcare theory and practice by developing a conceptual framework that provides policy-makers and managers a practical understanding of factors that affect healthcare service quality.

    Administrative and surveillance data are used frequently in healthcare epidemiology and antimicrobial stewardship (HE&AS) research because of their wide availability and efficiency. However, data quality issues exist, requiring careful consideration and potential validation of data. This methods paper presents key considerations for using administrative and surveillance data in HE&AS, including types of data available and potential use, data limitations, and the importance of validation. After discussing these issues, we review examples of HE&AS research using administrative data with a focus on scenarios when their use may be advantageous. A checklist is provided to help aid study development in HE&AS using administrative data. Infect Control Hosp Epidemiol 2016;1-10.

    Patient loyalty is key to business success for healthcare providers and also for patient health outcomes. This study aims to identify determinants influencing patient loyalty to healthcare providers and propose an integrative conceptual model of the influencing factors. PubMed, CINAHL, OVID, ProQuest and Elsevier Science Direct databases were searched. Publications about determinants of patient loyalty to health providers were screened, and 13 articles were included. Date of publication, location of the research, sample details, objectives and findings/conclusions were extracted for 13 articles. Thirteen studies explored eight determinants: satisfaction, quality, value, hospital brand image, trust, commitment, organizational citizenship behavior and customer complaints. The integrated conceptual model comprising all the determinants demonstrated the significant positive direct impact of quality on satisfaction and value, satisfaction on trust and commitment, trust on commitment and loyalty, and brand image on quality and loyalty. This review identifies and models the determinants of patient loyalty to healthcare providers. Further studies are needed to explore the influence of trust, commitment, and switching barriers on patient loyalty. © The Author 2017.

  12. Healthcare Coinsurance Elasticity Coefficient Estimation Using Monthly Cross-sectional, Time-series Claims Data.

    Scoggins, John F; Weinberg, Daniel A

    2017-06-01

    Published estimates of the healthcare coinsurance elasticity coefficient have typically relied on annual observations of individual healthcare expenditures even though health plan membership and expenditures are traditionally reported in monthly units and several studies have stressed the need for demand models to recognize the episodic nature of healthcare. Summing individual healthcare expenditures into annual observations complicates two common challenges of statistical inference, heteroscedasticity, and regressor endogeneity. This paper estimates the elasticity coefficient using a monthly panel data model that addresses the heteroscedasticity and endogeneity problems with relative ease. Healthcare claims data from employees of King County, Washington, during 2005 to 2011 were used to estimate the mean point elasticity coefficient: -0.314 (0.015 standard error) to -0.145 (0.015 standard error) depending on model specification. These estimates bracket the -0.2 point estimate (range: -0.22 to -0.17) derived from the famous Rand Health Insurance Experiment. Copyright © 2016 John Wiley & Sons, Ltd.

    Hospital-discharged patients with schizoaffective disorder have a high risk of re-hospitalization. However, limited data exist evaluating critical post-discharge periods during which the risk of re-hospitalization is significant. Among hospital-discharged patients with schizoaffective disorder, we assessed pharmacotherapy adherence and healthcare utilization and costs during sequential 60-day clinical periods before schizoaffective disorder-related hospitalization and post-hospital discharge. From the MarketScan(®) Medicaid database (2004-2008), we identified patients (≥18 years) with a schizoaffective disorder-related inpatient admission. Study measures including medication adherence and healthcare utilization and costs were assessed during sequential preadmission and post-discharge periods. We conducted univariate and multivariable regression analyses to compare schizoaffective disorder-related and all-cause healthcare utilization and costs (in 2010 US dollars) between each adjacent 60-day post-discharge periods. No adjustment was made for multiplicity. We identified 1,193 hospital-discharged patients with a mean age of 41 years. The mean medication adherence rate was 46% during the 60-day period prior to index inpatient admission, which improved to 80% during the 60-day post-discharge period. Following hospital discharge, schizoaffective disorder-related healthcare costs were significantly greater during the initial 60-day period compared with the 61- to 120-day post-discharge period (mean US$2,370 vs US$1,765; p < 0.001), with rehospitalization (36%) and pharmacy (40%) accounting for over three-fourths of the initial 60-day period costs. Compared with the initial 60-day post-discharge period, both all-cause and schizoaffective disorder-related costs declined during the 61- to 120-day post-discharge period and remained stable for the remaining post-discharge periods (days 121-365). We observed considerably lower (46%) adherence during 60 days prior to the

    Integrative medicine refers to ongoing efforts to combine the best of conventional and evidence-based complementary therapies. While this effort for collaboration is increasing, traditional complementary and alternative medicine (TM-CAM) remains poorly integrated into the current healthcare system of Ghana. At present, it is not clear if practitioners of mainstream medicine favor integrative medicine. The present study, therefore, sought to explore the perceptions of conventional healthcare professionals on integrative medicine. A qualitative design composed of semi-structured interviews was conducted with 23 conventional healthcare professionals comprising pharmacists, physicians, nurses and dieticians from two quasi-government hospitals in Accra, Ghana. Participants' knowledge of TM-CAM was low, and although they perceived alternative medicine as important to current conventional healthcare in Ghana, they expressed anxieties about the potential negative effects of the use of TM-CAM. This paradox was found to account for the low levels of use among these professionals, as well as the low level of recommendation to their patients. The practitioners surveyed recommended that alternative medicine could be integrated into mainstream allopathic healthcare in Ghana through improving knowledge, training as well as addressing concerns of safety and efficacy. These findings are discussed under the themes: the knowledge gap, the paradox of TM-CAM, experience of use and prescription, and guided integration. We did not observe any differences in views among the participants. The conventional healthcare professionals were ready to accept the idea of integrative medicine based on knowledge of widespread use and the potential role of TM-CAM products and practices in improving healthcare delivery in the country. However, to achieve an institutional integration, practitioners' understanding of TM-CAM must be improved, with specific attention to issues of safety, regulation and

  15. Why healthcare providers merge.

    In many OECD countries, healthcare sectors have become increasingly concentrated as a result of mergers. However, detailed empirical insight into why healthcare providers merge is lacking. Also, we know little about the influence of national healthcare policies on mergers. We fill this gap in the literature by conducting a survey study on mergers among 848 Dutch healthcare executives, of which 35% responded (resulting in a study sample of 239 executives). A total of 65% of the respondents was involved in at least one merger between 2005 and 2012. During this period, Dutch healthcare providers faced a number of policy changes, including increasing competition, more pressure from purchasers, growing financial risks, de-institutionalisation of long-term care and decentralisation of healthcare services to municipalities. Our empirical study shows that healthcare providers predominantly merge to improve the provision of healthcare services and to strengthen their market position. Also efficiency and financial reasons are important drivers of merger activity in healthcare. We find that motives for merger are related to changes in health policies, in particular to the increasing pressure from competitors, insurers and municipalities.

    Breast cancer is the most common cancer among women in Malaysia. Therefore, it is highly important for the public to be educated on breast cancer and to know the steps to detect it early on. Healthcare providers are in the prime position to provide such education to the public due to their high knowledge regarding health and their roles in healthcare. The present systematic review involved studies conducted in recent years to analyze the knowledge, attitudes and behavior of Malaysian healthcare providers regarding breast cancer, in attempts to obtain an overall picture of how well equipped our healthcare providers are to provide optimal breast cancer education, and to see their perceptions and actual involvement in said education. The systematic review was conducted via a primary search of various databases and journal websites, and a secondary search of references used by eligible studies. Criteria for eligibility included being published from the year 2008 till present, being conducted in Malaysia, and being written in the English language. A total of two studies were eligible for this review. Findings show that Malaysian future and current healthcare providers have moderate knowledge on breast cancer, have a positive towards involvement of breast cancer education, but have poor actual involvement.

    Recently there has been increased focus on the need to modernize the healthcare information infrastructure in the United States.1–4 The U.S. healthcare industry is by far the largest in the world in both absolute dollars and in percentage of GDP (more than $1.5 trillion, or 15 percent of GDP). It is also fragmented and complex. These difficulties, coupled with an antiquated infrastructure for the collection of and access to medical data, lead to enormous inefficiencies and sources of error. Consumer, regulatory, and governmental pressure drive a growing consensus that the time has come to modernize the U.S. healthcare information infrastructure (HII). While such transformation may be disruptive in the short term, it will, in the future, significantly improve the quality, expediency, efficiency, and successful delivery of healthcare while decreasing costs to patients and payers and improving the overall experiences of consumers and providers. The launch of a national health infrastructure initiative in the United States in May 2004-with the goal of providing an electronic health record for every American within the next decade-will eventually transform the healthcare industry in general, just as information technology (IT) has transformed other industries in the past. The key to this successful outcome will be based on the way we apply IT to healthcare data and the services delivered through IT. This must be accomplished in a way that protects individuals and allows competition but gives caregivers reliable and efficient access to the data required to treat patients and to improve the practice of medical science. This paper describes key IT solutions and technologies that address the challenges of creating a nation-wide healthcare IT infrastructure. Furthermore we discuss the emergence of new electronic healthcare services and the current efforts of IBM Research, Software Group, and Healthcare Life Sciences to realize this new vision for healthcare.

    Aims. To undertake a systematic review of the recent (2008–2013) primary literature, describing views and experiences of CAM use during pregnancy by women and healthcare professionals. Method. Medline, Cumulative Index to Nursing and Allied Health Literature, Cochrane Database of Systematic Review Library and Allied, and Complementary Medicine Database were searched. Studies reporting systemic CAM products (homeopathic preparations, herbal medicines, Vitamins and minerals, homeopathy, and special diets) alone or in combination with other nonsystemic CAM modalities (e.g., acupuncture) were included. Results. Database searches retrieved 2,549 citations. Removal of duplicates followed by review of titles and abstracts yielded 32 relevant studies. Twenty-two reported the perspectives of women and their CAM use during pregnancy, while 10 focused on healthcare professionals. The majority of studies had significant flaws in study design and reporting, including a lack of appropriate definitions of CAM and associated modalities, absence of detailed checklists provided to participants, the use of convenience sampling, and a general lack of scientific robustness in terms of data validity and reliability. Conclusion. To permit generalisability of study findings, there is an urgent need to expand the evidence base assessing CAMs use during pregnancy using appropriately designed studies. PMID:24194778

    Burnout is a work-related mental health impairment, which is now recognized as a real problem in the context of the helping professions due to its adverse health outcomes on efficiency. To our knowledge, the literature on the postdisaster scenario in Italy is limited by a focus on mental health professionals rather than other health-care workers. Our cross-sectional study aims to evaluate the prevalence of burnout and psychopathological distress in different categories of health-care workers, i.e., physicians, nurses, and health-care assistants, working in different departments of L’Aquila St. Salvatore General Hospital 6 years after the 2009 earthquake in order to prevent and reduce work-related burnout. With a two-stage cluster sampling, a total of 8 departments out of a total of 28 departments were selected and the total sample included 300 health-care workers. All the participants completed the following self-reporting questionnaires: a sociodemographic data form, a Maslach Burnout Inventory and a General Health Questionnaire 12 Items (GHQ-12). Statistically significant differences emerged between the total scores of the GHQ-12: post hoc analysis showed that the total average scores of the GHQ-12 were significantly higher in doctors than in health-care assistants. A high prevalence of burnout among doctors (25.97%) emerged. Using multivariate analysis, we identified a hostile relationship with colleagues, direct exposure to the L’Aquila earthquake and moderate to high levels of distress as being burnout predictors. Investigating the prevalence of burnout and distress in health-care staff in a postdisaster setting and identifying predictors of burnout development such as stress levels, time-management skills and work-life balance will contribute to the development of preventative strategies and better organization at work with a view to improving public health efficacy and reducing public health costs, given that these workers live in the disaster

    Norway has initiated a publicly funded rotavirus immunization program for all age-eligible children in 2014. We aimed to estimate the healthcare costs of rotavirus gastroenteritis in children younger than 5 years old. We identified all gastroenteritis cases in children younger than 5 years old treated during 2009-2013 through the national claims database for primary care and the national hospital registry. We estimated direct medical costs of rotavirus-associated primary care consultations and hospital encounters (inpatient admission, outpatient visit and ambulatory care). We performed a range of one-way sensitivity analyses to explore uncertainty in the cost estimates. Before vaccine introduction, the mean healthcare cost of rotavirus gastroenteritis in children younger than 5 years old was €4,440,337 per year. Among rotavirus-associated costs, 92% were hospital costs and the remaining 8% were primary care costs. The mean annual cost of rotavirus-associated hospital encounters was €4,083,691, of which 95% were costs of inpatient hospital admissions. The average healthcare cost of medically attended gastroenteritis in children younger than 5 years old was approximately €8 million per year, of which rotavirus-related costs represented 56%. Healthcare costs of rotavirus gastroenteritis in Norway are substantial. The cost-effectiveness of ongoing rotavirus immunization program should be reassessed.

    Despite the legal authority to confirm, override or modify healthcare insurance decisions made by physicians and government officials, health tribunal decisions have not been empirically analyzed. Using a novel quantitative methodology, all 387 Health Services Appeal and Review Board written and publicly available electronic decisions released over a five-year time period were statistically analyzed with respect to Ontario public health insurance requests for global cross-border healthcare. The statistical results found that patients knew their diagnosis prior to requesting cross-border healthcare, and 84% of patients requested specific northern US facilities for specific treatment. Two specific healthcare facilities in the US were requested for either surgery or assessments. A significant number of patients were seeking cross-border healthcare for pain treatment. This research challenges the assumption that cross-border treatment requests result only from domestic delay when instead patients are seeking specific treatments at specific facilities. This novel quantitative research methodology and data source of written and publicly available electronic Health Services Appeal and Review Board decisions should be used to inform policy decision regarding the utilization and evaluation of Canada's healthcare system and publicly funded healthcare insurance.

    National databases are used with increasing frequency in spine surgery literature to evaluate patient outcomes. The differences between individual databases in relationship to outcomes of lumbar fusion are not known. We evaluated the variability in standard outcomes of posterior lumbar fusion between the University HealthSystem Consortium (UHC) database and the Healthcare Cost and Utilization Project National Inpatient Sample (NIS). NIS and UHC databases were queried for all posterior lumbar fusions (International Classification of Diseases, Ninth Revision code 81.07) performed in 2012. Patient demographics, comorbidities (including obesity), length of stay (LOS), in-hospital mortality, and complications such as urinary tract infection, deep venous thrombosis, pulmonary embolism, myocardial infarction, durotomy, and surgical site infection were collected using specific International Classification of Diseases, Ninth Revision codes. Analysis included 21,470 patients from the NIS database and 14,898 patients from the UHC database. Demographic data were not significantly different between databases. Obesity was more prevalent in UHC (P = 0.001). Mean LOS was 3.8 days in NIS and 4.55 in UHC (P < 0.0001). Complications were significantly higher in UHC, including urinary tract infection, deep venous thrombosis, pulmonary embolism, myocardial infarction, surgical site infection, and durotomy. In-hospital mortality was similar between databases. NIS and UHC databases had similar demographic patient populations undergoing posterior lumbar fusion. However, the UHC database reported significantly higher complication rate and longer LOS. This difference may reflect academic institutions treating higher-risk patients; however, a definitive reason for the variability between databases is unknown. The inability to precisely determine the basis of the variability between databases highlights the limitations of using administrative databases for spinal outcome analysis. Copyright

  5. A Web-based Tool for SDSS and 2MASS Database Searches

    NASA Astrophysics Data System (ADS)

    Hendrickson, M. A.; Uomoto, A.; Golimowski, D. A.

    We have developed a web site using HTML, Php, Python, and MySQL that extracts, processes, and displays data from the Sloan Digital Sky Survey (SDSS) and the Two-Micron All-Sky Survey (2MASS). The goal is to locate brown dwarf candidates in the SDSS database by looking at color cuts; however, this site could also be useful for targeted searches of other databases as well. MySQL databases are created from broad searches of SDSS and 2MASS data. Broad queries on the SDSS and 2MASS database servers are run weekly so that observers have the most up-to-date information from which to select candidates for observation. Observers can look at detailed information about specific objects including finding charts, images, and available spectra. In addition, updates from previous observations can be added by any collaborators; this format makes observational collaboration simple. Observers can also restrict the database search, just before or during an observing run, to select objects of special interest.

    Arab Israeli women are subject to unique social stresses deriving from their status as part of an ethno-political minority and from their position as women in a patriarchal community. Collectively, their health profiles rate poorly in comparison to Jewish Israeli women or to women in the vast majority of developed countries. To examine the experiences of Arab Israeli women in the contemporary Israeli healthcare system, following implementation of the National Health Insurance Law (NHIL). The study combined quantitative and qualitative research methodologies. A telephone survey utilizing a structured questionnaire was conducted during August-September 1998 among a random national sample of 849 women, with a response rate of 83%. Between the months of January and July of 2000, qualitative data was attained via participant-observation, long and short semi-structured interviews, and focus groups in one large Muslim Arab Israeli village. Arab Israeli women in the national survey reported poorer self-assessed health, lower rates of care by a woman primary care physician, lower satisfaction ratings for primary care physicians and more frequently foregoing medical care than did native or immigrant Jewish Israeli women. Three major factors contributing to Arab Israeli women's healthcare experiences were elucidated by the qualitative study: (1) the threat of physical and social exposure (2) difficulties in communicating with male physicians and (3) the stifling effect of family politics and surveillance on healthcare. We discuss our findings in relation to structural changes associated with the recent reform of the Israeli health care system. We conclude by suggesting policy measures for better adapting primary care services to the needs of Arab Israeli women, and note the relevance to other systems that aim to provide service to cultural and ethno-political minorities, in which healthcare delivery is shaped by unique local circumstances.

    This article provides an overview and synthesis of the 100 most cited healthcare simulation publications to provide insight into the articles that have shaped current knowledge and practice. Searches of the Scopus and Web of Science databases were conducted in July 2017. Most articles were concerned with medical education and training (86%) and were most often published in surgical journals (33%). Manikins (20%), standardized patients (16%), inanimate part-task trainers (16%), fully simulated environments (17%), and virtual reality part-task trainers (14%) were the most commonly featured types of simulators. Healthcare simulation research has matured and grown during the preceding decades. There has been a move away from research questions focused on "does simulation work?" to an assessment of the conditions under which simulation is most effective. It is hoped that providing an overview of highly cited works will help identify topics for further research.

    We explore relationships between health information seeking activities and engagement with healthcare professionals via a privacy-sensitive analysis of geo-tagged data from mobile devices. We analyze logs of mobile interaction data stripped of individually identifiable information and location data. The data analyzed consist of time-stamped search queries and distances to medical care centers. We examine search activity that precedes the observation of salient evidence of healthcare utilization (EHU) (ie, data suggesting that the searcher is using healthcare resources), in our case taken as queries occurring at or near medical facilities. We show that the time between symptom searches and observation of salient evidence of seeking healthcare utilization depends on the acuity of symptoms. We construct statistical models that make predictions of forthcoming EHU based on observations about the current search session, prior medical search activities, and prior EHU. The predictive accuracy of the models varies (65%-90%) depending on the features used and the timeframe of the analysis, which we explore via a sensitivity analysis. We provide a privacy-sensitive analysis that can be used to generate insights about the pursuit of health information and healthcare. The findings demonstrate how large-scale studies of mobile devices can provide insights on how concerns about symptomatology lead to the pursuit of professional care. We present new methods for the analysis of mobile logs and describe a study that provides evidence about how people transition from mobile searches on symptoms and diseases to the pursuit of healthcare in the world.

  10. ED healthcare professionals and their notions of productivity.

    Moffatt, Fiona; Timmons, Stephen; Coffey, Frank

    2016-11-01

    The combination of constrained resources, patient complexity and rapidly increasing demand has meant that healthcare productivity constitutes a significant problem for emergency medicine. However, healthcare productivity remains a contentious issue, with some criticising the level of professional engagement. This paper will propose that productivity improvements in healthcare could occur (and be sustained) if professionals' perceptions and views of productivity were better understood. An 8-month ethnographic study was conducted in a large UK ED, using semistructured interviews with healthcare professionals (HCPs) (n=26), a focus group and observation. Thematic analysis of the data was undertaken based on an interpretivist philosophy. The data demonstrate that HCPs accept productivity improvement as part of their contemporary professional role. In particular, their understanding of productivity is focused around five key domains: the patient; the professional; the culture; the process of work and the economic. By exploring how these HCPs experienced and made sense of productivity improvement and productive healthcare, the data reveals how HCPs may reconcile a culture of caring with one of efficiency. Understanding healthcare productivity from this perspective has potential implications for service improvement design and performance measurement. Published by the BMJ Publishing Group Limited.

    To examine the role of healthcare professionals in the organ donation and transplantation process. Globally, there remains a perennial disequilibrium between organ donation and organ transplantation. Several factors account for this disequilibrium; however, as healthcare professionals are not only strategically positioned as the primary intermediaries between organ donors and transplant recipients, but also professionally situated as the implementers of organ donation and transplantation processes, they are often blamed for the global organ shortage. Mixed-method systematic review using the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols 2015 checklist. Databases were searched including CINAHL, MEDLINE, Web of Science and EMBASE using the search terms "organ donation," "healthcare professionals," "awareness" and "roles" to retrieve relevant publications. Thirteen publications met the inclusion criteria. The global organ shortage is neither contingent upon unavailability of suitable organs nor exclusively dependent upon healthcare professionals. Instead, the existence of disequilibrium between organ donation and transplantation is necessitated by a web of factors. These include the following: healthcare professionals' attitudes towards, and experience of, the organ donation and transplantation process, underpinned by professional education, specialist clinical area and duration of professional practice; conflicts of interests; ethical dilemmas; altruistic values towards organ donation; and varied organ donation legislations in different legal jurisdictions. This review maintains that if this web of factors is to be adequately addressed by healthcare systems in different global and legal jurisdictions, there should be sufficient organs voluntarily donated to meet all transplantation needs. There is a suggestion that healthcare professionals partly account for the global shortage in organ donation, but there is a need to examine how

    Importance At the turn of the 21st century, studies evaluating the change in incidence of appendicitis over time have reported inconsistent findings. Objectives We compared the differences in the incidence of appendicitis derived from a pathology registry versus an administrative database in order to validate coding in administrative databases and establish temporal trends in the incidence of appendicitis. Design We conducted a population-based comparative cohort study to identify all individuals with appendicitis from 2000 to2008. Setting & Participants Two population-based data sources were used to identify cases of appendicitis: 1) a pathology registry (n = 8,822); and 2) a hospital discharge abstract database (n = 10,453). Intervention & Main Outcome The administrative database was compared to the pathology registry for the following a priori analyses: 1) to calculate the positive predictive value (PPV) of administrative codes; 2) to compare the annual incidence of appendicitis; and 3) to assess differences in temporal trends. Temporal trends were assessed using a generalized linear model that assumed a Poisson distribution and reported as an annual percent change (APC) with 95% confidence intervals (CI). Analyses were stratified by perforated and non-perforated appendicitis. Results The administrative database (PPV = 83.0%) overestimated the incidence of appendicitis (100.3 per 100,000) when compared to the pathology registry (84.2 per 100,000). Codes for perforated appendicitis were not reliable (PPV = 52.4%) leading to overestimation in the incidence of perforated appendicitis in the administrative database (34.8 per 100,000) as compared to the pathology registry (19.4 per 100,000). The incidence of appendicitis significantly increased over time in both the administrative database (APC = 2.1%; 95% CI: 1.3, 2.8) and pathology registry (APC = 4.1; 95% CI: 3.1, 5.0). Conclusion & Relevance The administrative database overestimated the incidence of appendicitis

    Background Healthcare providers are considered the primary conduit of compassion in healthcare. Although most healthcare providers desire to provide compassion, and patients and families expect to receive it, an evidence-based understanding of the construct and its associated dimensions from the perspective of healthcare providers is needed. Objectives The aim of this study was to investigate healthcare providers’ perspectives and experiences of compassion in order to generate an empirically derived, clinically informed model. Design Data were collected via focus groups with frontline healthcare providers and interviews with peer-nominated exemplary compassionate healthcare providers. Data were independently and collectively analysed by the research team in accordance with Straussian grounded theory. Setting and participants 57 healthcare providers were recruited from urban and rural palliative care services spanning hospice, home care, hospital-based consult teams, and a dedicated inpatient unit within Alberta, Canada. Results Five categories and 13 associated themes were identified, illustrated in the Healthcare Provider Compassion Model depicting the dimensions of compassion and their relationship to one another. Compassion was conceptualised as—a virtuous and intentional response to know a person, to discern their needs and ameliorate their suffering through relational understanding and action. Conclusions An empirical foundation of healthcare providers’ perspectives on providing compassionate care was generated. While the dimensions of the Healthcare Provider Compassion Model were congruent with the previously developed Patient Model, further insight into compassion is now evident. The Healthcare Provider Compassion Model provides a model to guide clinical practice and research focused on developing interventions, measures and resources to improve it. PMID:29540416

    Significant portions of patients undergoing colorectal surgical procedures have minor incision disturbances, yet very few meet definitions for surgical site infection (SSI). We sought to investigate the natural history of incision disturbances with a focus on the patient experience and resource utilization. We hypothesize that patients who have an incision disturbance consume frequent healthcare resources in the post-operative period despite the fact that most never receive a diagnosis of SSI. A 24-month prospective observational study was undertaken at an academic institution. Patients undergoing elective colorectal operation by two board-certified colorectal surgeons were followed prospectively for 90 days. Incisions were photographed serially and clinically characterized beginning as early as post-operative day two and at follow-up visits. The primary outcome was patient concern for an incision disturbance. Three surgeons reviewed clinical data and photographs to determine the presence of an incisional surgical infection, and diagnosis required agreement from two of three surgeons. There were 171 patients included; 31 (15%) sought evaluation from a healthcare provider for concerns related to their incision including 46 telephone calls, six emergency department visits, seven primary care visits, 10 home health and 40 surgical clinic visits. Incision erythema and drainage were the most common sources of patient concern. Mean body mass index was higher in patients with concern for incision disturbances (34 vs. 28 kg/m 2 , p < 0.0001). Ultimately, 8% (14/171) received a diagnosis of SSI by study criteria while only 2% (4/171) were captured as having an SSI by the institutional National Surgical Quality Improvement Program database (p < 0.0001). Patients undergoing colorectal surgical procedures commonly are concerned with post-operative incision disturbance, yet few are associated with a diagnosis of SSI, and in-person evaluation yields frequent

    Authentic early experience in clinical contexts adds interest and relevance to basic medical education, and is regarded positively by both learners and teachers. However, with the recent expansion of medical education, the healthcare system appears close to reaching its capacity for student supervision. This study explores the utilisation of the healthcare system for early clinical placements. A secondary analysis was conducted of data from the Medical Schools Outcomes Database, collected from the 2010 annual questionnaire, focusing on the timing, duration and location of clinical placements during 2009 within the first half of basic medical education programs in Australia. Data was received for 67% of Australian medical students, reporting a total of 16 812 early clinical placements that occupied 97 319 days of supervised time in a wide variety of hospital, general practice and Indigenous health contexts, both urban and rural, across the Australian healthcare system. These early placements occupied about 16% of total clinical placement time for all students in all training years during 2009. The majority of these placements were for only a few hours or days; exceptions were longitudinal placements in regional and rural communities at a minority of schools. Early clinical placements may pose significant resource costs for placement providers, particularly supervision time and expertise. As medical education expands and the teaching capacity of the Australian healthcare system appears to reach its limits, it may be necessary to allocate placements according to their specific learning outcomes, prioritise more acute settings for more senior students, and increase capacity in less acute health and social care settings.

    A key challenge of preconception healthcare is identifying how it can best be delivered at a population level. To review current strategies of preconception healthcare, explore methods of preconception healthcare delivery, and develop public health models which reflect different preconception healthcare pathways. Preconception care strategies, programmes and evaluations were identified through a review of Medline and Embase databases. Search terms included: preconception, pre-pregnancy, intervention, primary care, healthcare, model, delivery, program, prevention, trial, effectiveness, congenital disorders OR abnormalities, evaluation, assessment, impact. Inclusion criteria for review articles were: (1) English, (2) human subjects, (3) women of childbearing age, (4) 1980–current data, (5) all countries, (6) both high risk and universal approaches, (7) guidelines or recommendations, (8) opinion articles, (9) experimental studies. Exclusion criteria were: (1) non-human subjects, (2) non-English, (3) outside of the specified timeframe, (4) articles on male healthcare. The results of the literature review were synthesised into public health models of care: (1) primary care; (2) hospital-based and inter-conception care; (3) specific preconception care clinics; and, (4) community outreach. Fifteen evaluations of preconception care were identified. Community programmes demonstrated a significant impact on substance use, folic acid supplementation, diabetes optimization, and hyperphenylalaninemia. An ideal preconception visits entail risk screening, education, and intervention if indicated. Subsequently, four public health models were developed synthesizing preconception care delivery at a population level. Heterogeneity of risk factors, health systems and strategies of care reflect the lack of consensus about the best way to deliver preconception care. The proposed models aim to reflect differing aspects of preconception healthcare delivery.

    With three missions outstanding, the Shuttle Hypervelocity Impact Database has nearly 3000 entries. The data is divided into tables for crew module windows, payload bay door radiators and thermal protection system regions, with window impacts compromising just over half the records. In general, the database provides dimensions of hypervelocity impact damage, a component level location (i.e., window number or radiator panel number) and the orbiter mission when the impact occurred. Additional detail on the type of particle that produced the damage site is provided when sampling data and definitive analysis results are available. Details and insights on the contents of the database including examples of descriptive statistics will be provided. Post flight impact damage inspection and sampling techniques that were employed during the different observation campaigns will also be discussed. Potential enhancements to the database structure and availability of the data for other researchers will be addressed in the Future Work section. A related database of returned surfaces from the International Space Station will also be introduced.

    2016-04-01

    This work summarizes the design and application of a Quality Control (QC) procedure for an observational surface wind database located in North Eastern North America. The database consists of 526 sites (486 land stations and 40 buoys) with varying resolutions of hourly, 3 hourly and 6 hourly data, compiled from three different source institutions with uneven measurement units and changing measuring procedures, instrumentation and heights. The records span from 1953 to 2010. The QC process is composed of different phases focused either on problems related with the providing source institutions or measurement errors. The first phases deal with problems often related with data recording and management: (1) compilation stage dealing with the detection of typographical errors, decoding problems, site displacements and unification of institutional practices; (2) detection of erroneous data sequence duplications within a station or among different ones; (3) detection of errors related with physically unrealistic data measurements. The last phases are focused on instrumental errors: (4) problems related with low variability, placing particular emphasis on the detection of unrealistic low wind speed records with the help of regional references; (5) high variability related erroneous records; (6) standardization of wind speed record biases due to changing measurement heights, detection of wind speed biases on week to monthly timescales, and homogenization of wind direction records. As a result, around 1.7% of wind speed records and 0.4% of wind direction records have been deleted, making a combined total of 1.9% of removed records. Additionally, around 15.9% wind speed records and 2.4% of wind direction data have been also corrected.

    Type 2 diabetes poses an increasing healthcare burden in Japan. Although insulin treatment has diversified in recent years, the literature on the utilization of healthcare services among patients with type 2 diabetes undergoing different insulin therapy regimens is scarce. The current study aimed to characterize the real-world insulin treatment patterns and associated utilization of healthcare services among patients with type 2 diabetes who initiated insulin therapy during the study period. We examined data from a hospital-based database consisting of administrative and laboratory data from 121 acute-phase hospitals throughout Japan from April 2008 to August 2012. Patients diagnosed with type 2 diabetes and receiving continuous insulin therapy, defined by three insulin claims or more, were included in the analysis. Of the 2,145 insulin initiators, at initiation 46.5% received rapid-acting insulin alone, 36.6% received an intensive regimen, 11.4% received long-acting insulin alone, and 5.5% received pre-mixed insulin alone. Patients treated with rapid-acting insulin alone were older, experienced more comorbid conditions, had lower HbA1c, and more often had initiated their insulin treatment at inpatient admission, compared to patients treated with other types of insulin. Inpatient admission was more common and longer for patients taking rapid-acting insulin and an intensive regimen than those taking long-acting or pre-mixed insulin, and most were readmitted within 1 year. Utilization of outpatient clinics was approximately once per month, and emergency department visits were observed to be rare. This retrospective observational descriptive study found varied treatment and healthcare service utilization patterns, as well as disparities in patient characteristics across insulin regimens. Future research should assess the basis for these various utilization patterns associated with insulin to conduct robust analyses of clinical and economic outcomes.

    The aim of this study was to describe characteristics and external validity of the German Health Risk Institute (HRI) Database. The HRI Database is an anonymized healthcare database with longitudinal data from approximately six Mio Germans. In addition to demographic information (gender, age, region of residence), data on persistence of insurants over time, hospitalization rates, mortality rates and drug prescription rates were extracted from the HRI database for 2013. Corresponding national reference data were obtained from official sources. The proportion of men and women was similar in the HRI Database and Germany, but the database population was slightly younger (mean 40.4 vs 43.7 years). The proportion of insurants living in the eastern part of Germany was lower in the HRI Database (10.1% vs 19.7%). There was good accordance to German reference data with respect to hospitalization rates, overall mortality rate and prescription rates for the 20 most often reimbursed drug classes, with the overall burden of morbidity being slightly lower in the HRI database. From insurants insured on 1 January 2009 (N = 6.2 Mio), a total of 70.6% survived and remained continuously insured with the same statutory health insurance until 31 December 2013. This proportion increased to 77.5% if only insurants ≥40 years were considered. There was good overall accordance of the HRI database and the German population in terms of measures of morbidity, mortality and drug usage. Persistence of insurants with the database over time was high, indicating suitability of the data source for longitudinal epidemiological analyses. Copyright © 2015 John Wiley & Sons, Ltd.

    2005-05-04

    BACKGROUND: The U.S. National Healthcare Disparities Report is a recent effort to measure and monitor racial and ethnic disparities in health and healthcare. The Report is a work in progress and includes few indicators specific to children. An indicator worthy of consideration is racial/ethnic differences in the rate of bad outcomes for pediatric acute appendicitis. Bad outcomes for this condition are indicative of poor access to healthcare, which is amenable to social and healthcare policy changes. METHODS: We analyzed the KID Inpatient Database, a nationally representative sample of pediatric hospitalization, to compare rates of appendicitis rupture between white, African American, Hispanic and Asian children. We ran weighted logistic regression models to obtain national estimates of relative odds of rupture rate for the four groups, adjusted for developmental, biological, socioeconomic, health services and hospital factors that might influence disease outcome. RESULTS: Rupture was a much more burdensome outcome than timely surgery and rupture avoidance. Rupture cases had 97% higher hospital charges and 175% longer hospital stays than non-rupture cases on average. These burdens disproportionately affected minority children, who had 24% - 38% higher odds of appendicitis rupture than white children, adjusting for age and gender. These differences were reduced, but remained significant after adjusting for other factors. CONCLUSION: The racial/ethnic disparities in pediatric appendicitis outcome are large and are preventable with timely diagnosis and surgery for all children. Furthermore, estimating this disparity using the KID survey is a relatively straightforward process. Therefore pediatric appendicitis rupture rate is a good candidate for inclusion in the National Healthcare Disparities Report. As with most other health and healthcare disparities, efforts to reduce disparities in income, wealth and access to care will most likely improve the odds of favorable

    LGBT (lesbian, gay, bisexual, transgender) patients suffer from stigma and discrimination when seeking healthcare. A large LGBT healthcare survey revealed that 56% of gay patients and 70% of transgender patients suffered some type of discrimination while seeking healthcare in 2014. The fostering of LGBT-friendly healthcare services is not just an advanced step of gender mainstreaming but also a fulfillment of health equality and equity. Additionally, LGBT-friendly healthcare services are expected to provide new opportunities for healthcare workers. Therefore, proactive government policies, education, research, and clinical practice should all encourage the development of these healthcare services. We look forward to a well-developed LGBT-friendly healthcare system in Taiwan.

    We used qualitative methods (semi-structured interviews with healthcare providers) to explore: 1) the role of narratives as a vehicle for raising awareness and engaging providers about the issue of healthcare disparities and 2) the extent to which different ways of framing issues of race within narratives might lead to message acceptance for providers' whose preexisting beliefs about causal attributions might predispose them to resist communication about racial healthcare disparities. Individual interviews were conducted with 53 providers who had completed a prior survey assessing beliefs about disparities. Participants were stratified by the degree to which they believed providers contributed to healthcare inequality: low provider attribution (LPA) versus high provider attribution (HPA). Each participant read and discussed two differently framed narratives about race in healthcare. All participants accepted the "Provider Success" narratives, in which interpersonal barriers involving a patient of color were successfully resolved by the provider narrator, through patient-centered communication. By contrast, "Persistent Racism" narratives, in which problems faced by the patient of color were more explicitly linked to racism and remained unresolved, were very polarizing, eliciting acceptance from HPA participants and resistance from LPA participants. This study provides a foundation for and raises questions about how to develop effective narrative communication strategies to engage providers in efforts to reduce healthcare disparities.

    This study estimates the annual numbers of eight work-related cancers, total losses of quality-adjusted life years (QALYs), and lifetime healthcare expenditures that possibly could be saved by improving occupational health in Taiwan. Three databases were interlinked: the Taiwan Cancer Registry, the National Mortality Registry, and the National Health Insurance Research Database. Annual numbers of work-related cancers were estimated based on attributable fractions (AFs) abstracted from a literature review. The survival functions for eight cancers were estimated and extrapolated to lifetime using a semi-parametric method. A convenience sample of 8846 measurements of patients' quality of life with EQ-5D was collected for utility values and multiplied by survival functions to estimate quality-adjusted life expectancies (QALEs). The loss-of-QALE was obtained by subtracting the QALE of cancer from age- and sex-matched referents simulated from national vital statistics. The lifetime healthcare expenditures were estimated by multiplying the survival probability with mean monthly costs paid by the National Health Insurance for cancer diagnosis and treatment and summing this for the expected lifetime. A total of 3010 males and 726 females with eight work-related cancers were estimated in 2010. Among them, lung cancer ranked first in terms of QALY loss, with an annual total loss-of-QALE of 28,463 QALYs and total lifetime healthcare expenditures of US$36.6 million. Successful prevention of eight work-related cancers would not only avoid the occurrence of 3736 cases of cancer, but would also save more than US$70 million in healthcare costs and 46,750 QALYs for the Taiwan society in 2010.

    To examine whether hospital-based healthcare technology is related to 30-day postoperative mortality rates after adjusting for hospital volume of cardiovascular surgical procedures.This study used the National Health Insurance Service-Cohort Sample Database from 2002 to 2013, which was released by the Korean National Health Insurance Service. A total of 11,109 cardiovascular surgical procedure patients were analyzed. The primary analysis was based on logistic regression models to examine our hypothesis.After adjusting for hospital volume of cardiovascular surgical procedures as well as for all other confounders, the odds ratio (OR) of 30-day mortality in low healthcare technology hospitals was 1.567-times higher (95% confidence interval [CI] = 1.069-2.297) than in those with high healthcare technology. We also found that, overall, cardiovascular surgical patients treated in low healthcare technology hospitals, regardless of the extent of cardiovascular surgical procedures, had the highest 30-day mortality rate.Although the results of our study provide scientific evidence for a hospital volume-mortality relationship in cardiovascular surgical patients, the independent effect of hospital-based healthcare technology is strong, resulting in a lower mortality rate. As hospital characteristics such as clinical pathways and protocols are likely to also play an important role in mortality, further research is required to explore their respective contributions.

    The Multi-Societal Database Committee for Pediatric and Congenital Heart Disease was established in 2005 with the goal of providing the infrastructure, spanning geographical and subspecialty boundaries, for collaboration between health care professionals interested in the analysis of outcomes of treatments provided to patients with congenital cardiac disease, with the ultimate aim of improvement in the quality of care provided to these patients. The purpose of these collaborative efforts is to promote the highest quality comprehensive cardiac care to all patients with congenital heart disease, from the fetus to the adult, regardless of the patient's economic means, with an emphasis on excellence in teaching, research and community service. This manuscript provides the Introduction to the 2008 Supplement to Cardiology in the Young titled: "Databases and The Assessment of Complications associated with the Treatment of Patients with Congenital Cardiac Disease". This Supplement was prepared by The Multi-Societal Database Committee for Pediatric and Congenital Heart Disease. The Multi-Societal Database Committee for Pediatric and Congenital Heart Disease offers the following definition of the term "Complication": "A complication is an event or occurrence that is associated with a disease or a healthcare intervention, is a departure from the desired course of events, and may cause, or be associated with, suboptimal outcome. A complication does not necessarily represent a breech in the standard of care that constitutes medical negligence or medical malpractice. An operative or procedural complication is any complication, regardless of cause, occurring (1) within 30 days after surgery or intervention in or out of the hospital, or (2) after 30 days during the same hospitalization subsequent to the operation or intervention. Operative and procedural complications include both intraoperative/intraprocedural complications and postoperative/postprocedural complications in this

    The present study evaluates how five sectors of two Brazilian hospitals have implemented lean healthcare concepts in their operations. The main characteristics of the implementation process are analyzed in the present study: the motivational factor for implementation, implementation time, form (consultancy or internal), team (hospital and consultants), lean implementation continuity/sustainability, lean healthcare tools and methods implemented, problems/improvement opportunities, lean healthcare barriers faced during the implementation process, and critical factors that affected the implementation and the results obtained in each case. The case studies indicate that reducing patient lead times and costs and making financial improvements were the primary factors that motivated lean healthcare implementation in the hospitals studied. Several tools and methods were used in the cases studied, especially value stream mapping and DMAIC. The barriers found in both hospitals are primarily associated with the human factor. Additionally, the results obtained after implementation were analyzed and improvements in financial aspects, productivity and capacity, and lead time reduction of the analyzed sectors were observed. Further, this study also exhibited four propositions elaborated from the results obtained from the cases that highlighted barriers and challenges to lean healthcare implementation in developing countries. Two of these barriers are hospital organizational structure (and, consequently, how the senior management works with medical staff), and outsourcing hospital activities. This study also concluded that the initialization and maintenance of lean healthcare implementation rely heavily on external support because lean healthcare subject knowledge is not yet available in the healthcare organization, which represents a challenge.

    Noncontact electrocardiogram (ECG) measurement technique has gained popularity these days owing to its noninvasive features and convenience in daily life use. This paper presents mobile cloud computing for a healthcare system where a noncontact ECG measurement method is employed to capture biomedical signals from users. Healthcare service is provided to continuously collect biomedical signals from multiple locations. To observe and analyze the ECG signals in real time, a mobile device is used as a mobile monitoring terminal. In addition, a personalized healthcare assistant is installed on the mobile device; several healthcare features such as health status summaries, medication QR code scanning, and reminders are integrated into the mobile application. Health data are being synchronized into the healthcare cloud computing service (Web server system and Web server dataset) to ensure a seamless healthcare monitoring system and anytime and anywhere coverage of network connection is available. Together with a Web page application, medical data are easily accessed by medical professionals or family members. Web page performance evaluation was conducted to ensure minimal Web server latency. The system demonstrates better availability of off-site and up-to-the-minute patient data, which can help detect health problems early and keep elderly patients out of the emergency room, thus providing a better and more comprehensive healthcare cloud computing service.

    Proponents of the healthcare reform agenda continually compare per capita healthcare spending in the United States to other nations and cite this as one of the clear mandates for healthcare reform. The purpose of this article is to draw attention to the cost of geographic distribution strategies adopted by healthcare organizations and the impact this has on per capita healthcare costs. It is important to quantify the cost of such strategies and to weigh their merits, if the intent is to substantially reduce the cost of healthcare in the United States.

    To systematically review the literature on the effect of providing oral healthcare education to care home nurses on their oral healthcare knowledge and attitude and their oral hygiene care skills. A literature search was obtained for relevant articles on oral healthcare education of nurses in care homes, using five electronic retrieval systems and databases. The search was limited to human studies, articles published in English and articles published during the period January 1990 to December 2011. The methodological quality of an article was assessed on the basis of criteria published by the Cochrane Collaboration. For articles not meeting all methodological quality criteria, relevance criteria were used to determine how much scientific evidence could be assigned to the study findings. In accordance with the methodological quality criteria, two randomized controlled trials were included. Additionally, four studies were included after determining the scientific evidence of the study findings. The studies included revealed some scientific evidence and indications that an oral healthcare education programme for care home nurses may improve the nurses' oral healthcare knowledge and attitude. Any effect of oral healthcare education to care home nurses' oral hygiene care skills could not be determined. Oral healthcare education may have a positive effect on care home nurses' oral healthcare knowledge and attitude and on care home residents' oral hygiene, whereas any effect on care home nurses' oral hygiene care skills could not be found. © 2013 John Wiley & Sons A/S.

    2013-01-01

    Food insecurity in older adults is a clinically relevant problem with important implications for healthcare costs; however, few studies have examined the relationship between food insecurity and the healthcare cost burden in older adults. It may be due in part to lack of appropriate data and methods to examine these issues in the existing datasets. It is critical to identify and obtain the data necessary for estimating healthcare costs associated with food insecurity and to explore specific mechanisms by which food insecurity is related to adverse health outcomes and associated healthcare costs. This paper discusses how to best utilize and link available, nationally representative datasets and develop infrastructure and procedures to establish state and local datasets. As an example, an innovative approach tested in Georgia to establish a state-level dataset in a sample of low-income, older adults in need of food assistance is discussed. In this approach, data from the state aging services client database and the Centers for Medicare and Medicaid Services data were linked. Such efforts are essential to estimate the healthcare cost burden of food-insecure older adults who have a particularly higher burden of chronic diseases and direct future research, program, and policy decisions to improve the food and healthcare security of low-income, older adults.

    Over the past few years, Saudi hospitals have been implementing and upgrading Electronic Medical Record Systems (EMRs) to ensure secure data transfer and exchange between EMRs.This paper focuses on the process and lessons learned in upgrading the MUMPS database to a the newer Caché database to ensure the integrity of electronic data transfer within a local Saudi hospital. This paper examines the steps taken by the departments concerned, their action plans and how the change process was managed. Results show that user satisfaction was achieved after the upgrade was completed. The system was stable and offered better healthcare quality to patients as a result of the data exchange. Hardware infrastructure upgrades improved scalability and software upgrades to Caché improved stability. The overall performance was enhanced and new functions were added (CPOE) during the upgrades. The essons learned were: 1) Involve higher management; 2) Research multiple solutions available in the market; 3) Plan for a variety of implementation scenarios.

    Patients living in rural areas often need to travel long distances for access to specialist care. To increase access to specialist care, video consultation between patients in primary healthcare and specialist care has been used. In order for this new method to be developed and used to the fullest, it is important to understand healthcare personnel's experiences with this intervention. The aim of this study was to describe healthcare personnel's experiences using video consultation in their work in primary healthcare. A mixed methods design was used, and the data were analysed using qualitative and quantitative analysis methods. Interviews were conducted with eight general practitioners and one district nurse, all of whom had conducted a video consultation with a patient and a specialist physician or a cardiac specialist nurse. After each video consultation, the participants completed a consultation report/questionnaire. Healthcare personnel considered video consultation to provide quicker access to specialist care for the patient, and greater security when the video consultation encounter was conducted at their own primary healthcare centre. They considered video consultation an opportunity to provide education and for the patients to ask questions. Video consultation is a satisfactory tool for healthcare personnel, and the technology is a new, useful method, especially for the district nurses. Further, video consultation is an opportunity for healthcare personnel to learn. However, for it to work as an accepted method, the technology must function well and be user friendly. It must also be clear that it is beneficial for the patients and the healthcare personnel.

    Assessing healthcare utilization is important to identify weaknesses of healthcare systems, to outline action points for preventive measures and interventions, and to more accurately estimate the disease burden in a population. A healthcare utilization survey was developed for the Typhoid Fever Surveillance in Africa Program (TSAP) to adjust incidences of salmonellosis determined through passive, healthcare facility-based surveillance. This cross-sectional survey was conducted at 11 sites in 9 sub-Saharan African countries. Demographic data and healthcare-seeking behavior were assessed at selected households. Overall and age-stratified percentages of each study population that sought healthcare at a TSAP healthcare facility and elsewhere were determined. Overall, 88% (1007/1145) and 81% (1811/2238) of the population in Polesgo and Nioko 2, Burkina Faso, respectively, and 63% (1636/2590) in Butajira, Ethiopia, sought healthcare for fever at any TSAP healthcare facility. A far smaller proportion-namely, 20%-45% of the population in Bissau, Guinea-Bissau (1743/3885), Pikine, Senegal (1473/4659), Wad-Medani, Sudan (861/3169), and Pietermaritzburg, South Africa (667/2819); 18% (483/2622) and 9% (197/2293) in Imerintsiatosika and Isotry, Madagascar, respectively; and 4% (127/3089) in Moshi, Tanzania-sought healthcare at a TSAP healthcare facility. Patients with fever preferred to visit pharmacies in Imerintsiatosika and Isotry, and favored self-management of fever in Moshi. Age-dependent differences in healthcare utilization were also observed within and across sites. Healthcare utilization for fever varied greatly across sites, and revealed that not all studied populations were under optimal surveillance. This demonstrates the importance of assessing healthcare utilization. Survey data were pivotal for the adjustment of the program's estimates of salmonellosis and other conditions associated with fever. © The Author 2016. Published by Oxford University Press for the

    To analyze the implementation of Medicaid preferred drug lists (PDLs) in a number of states and determine its impact on quality of care and cost relative to other segments of healthcare. We reviewed research and case studies found by searching library databases, primarily MEDLINE and EBSCOHost, and searching pertinent journals. Keywords initially included "drug lists," "prior authorization," "prior approval," and "Medicaid." We added terms such as "influence use of other healthcare services," "quality of care," and "overall economic impact." We mainly used primary sources. Based on our literature review, we determined that there are a number of issues regarding Medicaid PDLs that need to be addressed. Some issues include: (a) the potential for PDLs to influence the utilization of other healthcare services, (b) criteria used by Medicaid for determining acceptance of drugs onto a PDL, (c) the effect of PDL implementation on compliance to new regimens, (d) the potential effects of restricting medication availability on quality of care, (e) administrative costs associated with PDLs, and (f) satisfaction rates among patients and medical providers. This review highlighted expected short-term cost savings with limited degree of compromised quality of PDL implementation, but raised the concern about the potential long-term decline in quality of care and overall economic impact. The number of concerns raised indicates that further studies are warranted regarding both short-term cost benefits as well as potential long-term effects of Medicaid PDL implementation. Objective analysis of these effects is necessary to ensure cost-effectiveness and quality of care.

    There is a lack of population studies evaluating the impact of bariatric surgery (BRS) on all-cause inpatient mortality. We sought to determine the impact of prior BRS on all-cause mortality and healthcare utilization in hospitalized patients. We analyzed the National Inpatient Sample database from 2007 to 2013. Participants were adult (≥ 18 years) inpatients admitted with a diagnosis of morbid obesity or a history of BRS. Propensity score-matched analyses were performed to compare mortality and healthcare resource utilization (hospital length of stay and cost). There were 9,044,103 patient admissions with morbid obesity and 1,066,779 with prior BRS. A propensity score-matched cohort analysis demonstrated that prior BRS was associated with decreased mortality (OR = 0.58; 95% CI [0.54, 0.63]), shorter length of stay (0.59 days; P < 0.001), and lower hospital costs ($2152; P < 0.001) compared to morbid obesity. A subgroup of propensity score-matched analysis among patients with high-risk of mortality (leading ten causes of mortality in morbid obesity) revealed a consistently significant reduction in odds of mortality for patients with prior BRS (OR = 0.82; 95% CI [0.72, 0.92]). Hospitalized patients with a history of BRS have lower all-cause mortality and healthcare resource utilization compared to those who are morbidly obese. These observations support the continued application of BRS as an effective and resource-conscious treatment for morbid obesity.

    South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL) were searched for combinations of keywords including 'healthcare workers', 'risky sexual behaviour' and 'HIV and AIDS'. Articles from a range of countries met inclusion and exclusion criteria. Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

    Obesity-related stigma likely influences how obese people interact with health-care professionals and access health care. To undertake a synthesis of studies examining the views and experiences of both obese people in relation to their health-care provision and health-care professionals in providing care to obese patients. A systematic search of key electronic databases relating to professional or patient experiences of, or perspectives on, obesity was performed in 2008 and updated in 2010. Reference lists of article bibliographies were searched, along with hand searches of relevant journals.   Studies were screened against explicit inclusion criteria and published between 1990 and 2010. Findings were examined and organized thematically.   Data were extracted focusing on obesity, stigma and access to health-care services. All included studies were subject to critical appraisal to assess the quality of the research. Thirty studies were identified. All the studies reported obesity impacting on health-care interactions. Key themes identified were experiences of stigma and feelings of powerlessness, treatment avoidance, psycho-emotional functioning, professional attitudes, confidence and training, variations in health contact time and finally, differences in treatment options and preventative measures. Obesity is a stigmatized condition that impacts negatively on the relationship between patients and health-care providers. Given the increasing prevalence of obesity and the range of therapeutic options available, further work is necessary to understand how the presence of obesity affects health-care interactions and decision making. © 2011 John Wiley & Sons Ltd.

    It is increasingly necessary to generate medical evidence applicable to Asian people compared to those in Western countries. Observational Health Data Sciences a Informatics (OHDSI) is an international collaborative which aims to facilitate generating high-quality evidence via creating and applying open-source data analytic solutions to a large network of health databases across countries. We aimed to incorporate Korean nationwide cohort data into the OHDSI network by converting the national sample cohort into Observational Medical Outcomes Partnership-Common Data Model (OMOP-CDM). The data of 1.13 million subjects was converted to OMOP-CDM, resulting in average 99.1% conversion rate. The ACHILLES, open-source OMOP-CDM-based data profiling tool, was conducted on the converted database to visualize data-driven characterization and access the quality of data. The OMOP-CDM version of National Health Insurance Service-National Sample Cohort (NHIS-NSC) can be a valuable tool for multiple aspects of medical research by incorporation into the OHDSI research network.

    The cleaning profession has been associated with multiple ergonomic and chemical hazards which elevate the risk for occupational injury. This study investigated the epidemiology of occupational injury among cleaners in healthcare work settings in the Canadian province of British Columbia. Incidents of occupational injury among cleaners, resulting in lost time from work or medical care, over a period of 1 year in two healthcare regions were extracted from a standardized operational database and with person-years obtained from payroll data. Detailed analysis was conducted using Poisson regression modeling. A total of 145 injuries were identified among cleaners, with an annual incidence rate of 32.1 per 100 person-years. After adjustment for age, gender, subsector, facility, experience and employment status, Poisson regression models demonstrated that a significantly higher relative risk (RR) of all injury, musculoskeletal injury and cuts was associated with cleaning work in acute care facilities, compared with long-term care facilities. Female cleaners were at a higher RR of all injuries and contusions than male cleaners. A lower risk of all injury and allergy and irritation incidents among part-time or casual workers was found. Cleaners with >10 years of experience were at significantly lower risk for all injury, contusion and allergy and irritation incidents. Cleaners were found to be at an elevated risk of all injury categories compared with healthcare workers in general.

    Hospital-acquired infections (HAIs), including emerging multi-drug resistant organisms, threaten healthcare systems worldwide. Efficient containment measures of HAIs must mobilize the entire healthcare network. Thus, to best understand how to reduce the potential scale of HAI epidemic spread, we explore patient transfer patterns in the French healthcare system. Using an exhaustive database of all hospital discharge summaries in France in 2014, we construct and analyze three patient networks based on the following: transfers of patients with HAI (HAI-specific network); patients with suspected HAI (suspected-HAI network); and all patients (general network). All three networks have heterogeneous patient flow and demonstrate small-world and scale-free characteristics. Patient populations that comprise these networks are also heterogeneous in their movement patterns. Ranking of hospitals by centrality measures and comparing community clustering using community detection algorithms shows that despite the differences in patient population, the HAI-specific and suspected-HAI networks rely on the same underlying structure as that of the general network. As a result, the general network may be more reliable in studying potential spread of HAIs. Finally, we identify transfer patterns at both the French regional and departmental (county) levels that are important in the identification of key hospital centers, patient flow trajectories, and regional clusters that may serve as a basis for novel wide-scale infection control strategies.

    Chronic obstructive pulmonary disease (COPD) imparts a substantial economic burden on western health systems. Our objective was to analyze the determinants of elevated healthcare utilization among patients with COPD in a single-payer health system. Three-hundred eighty-nine adults with COPD were matched 1:3 to controls by age, gender and area of residency. Total healthcare cost 5 years prior recruitment and presence of comorbidities were obtained from a computerized database. Health related quality of life (HRQoL) indices were obtained using validated questionnaires among a subsample of 177 patients. Healthcare utilization was 3.4-fold higher among COPD patients compared with controls (p < 0.001). The "most-costly" upper 25% of COPD patients (n = 98) consumed 63% of all costs. Multivariate analysis revealed that independent determinants of being in the "most costly" group were (OR; 95% CI): age-adjusted Charlson Comorbidity Index (1.09; 1.01-1.2), history of: myocardial infarct (2.87; 1.5-5.5), congestive heart failure (3.52; 1.9-6.4), mild liver disease (3.83; 1.3-11.2) and diabetes (2.02; 1.1-3.6). Bivariate analysis revealed that cost increased as HRQoL declined and severity of airflow obstruction increased but these were not independent determinants in a multivariate analysis. Comorbidity burden determines elevated utilization for COPD patients. Decision makers should prioritize scarce health care resources to a better care management of the "most costly" patients.

    Europe is in the fortunate situation that it has a long tradition in phenological networking: the history of collecting phenological data and using them in climatology has its starting point in 1751 when Carl von Linné outlined in his work Philosophia Botanica methods for compiling annual plant calendars of leaf opening, flowering, fruiting and leaf fall together with climatological observations "so as to show how areas differ". The Societas Meteorologicae Palatinae at Mannheim well known for its first European wide meteorological network also established a phenological network which was active from 1781 to 1792. Recently in most European countries, phenological observations have been carried out routinely for more than 50 years by different governmental and non governmental organisations and following different observation guidelines, the data stored at different places in different formats. This has been really hampering pan European studies, as one has to address many National Observations Programs (NOP) to get access to the data before one can start to bring them in a uniform style. From 2004 to 2005 the COST-action 725 was running with the main objective to establish a European reference data set of phenological observations that can be used for climatological purposes, especially climate monitoring, and detection of changes. So far the common database/reference data set of COST725 comprises 7687248 data from 7285 observation sites in 15 countries and International Phenological Gardens (IPG) spanning the timeframe from 1951 to 2000. ZAMG is hosting the database. In January 2010 PEP725 has started and will take over not only the part of maintaining, updating the database, but also to bring in phenological data from the time before 1951, developing better quality checking procedures and ensuring an open access to the database. An attractive webpage will make phenology and climate impacts on vegetation more visible in the public enabling a monitoring of

    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.

  9. Managing today's complex healthcare business enterprise: reflections on distinctive requirements of healthcare management education.

    PubMed

    Welton, William E

    2004-01-01

    In early 2001, the community of educational programs offering master's-level education in healthcare management began an odyssey to modernize its approach to the organization and delivery of healthcare management education. The community recognized that cumulative long-term changes within healthcare management practice required a careful examination of healthcare management context and manpower requirements. This article suggests an evidence-based rationale for defining the distinctive elements of healthcare management, thus suggesting a basis for review and transformation of master's-level healthcare management curricula. It also suggests ways to modernize these curricula in a manner that recognizes the distinctiveness of the healthcare business enterprise as well as the changing management roles and careers within these complex organizations and systems. Through such efforts, the healthcare management master's-level education community would be better prepared to meet current and future challenges, to increase its relevance to the management practice community, and to allocate scarce faculty and program resources more effectively.

    2003-01-01

    The U.S. healthcare system requires radical, not incremental, change. Management issues in healthcare delivery are fundamentally different from those in the business world. Systems thinking forces a focus on corporate culture, about which there is little hard data. The use of cost/benefit analysis suffers from the lack of any accepted measure of long-term "benefit." The authors make four observations: (1) corporate culture is both part of the cause and part of the cure for healthcare; (2) long-term financial and functional measures are necessary to make evidence-based decisions; (3) valid, nationwide data must be developed regarding the corporate culture of medicine; and (4) direct (unmodified) application of management theory or practices will not achieve sustainable improvements.

    Globalisation has brought new possibilities for international growth in education and professional mobility among healthcare professionals. There has been a noticeable increase of international degree programmes in non-English speaking countries in Europe, creating clinical learning challenges for healthcare students. The aim of this systematic review was to describe mentors' experiences of international healthcare students' learning in a clinical environment. The objective of the review was to identify what influences the success or failure of mentoring international healthcare students when learning in the clinical environment, with the ultimate aim being to promote optimal mentoring practice. A systematic review was conducted according to the guidelines of the Centre for Reviews and Dissemination. Seven electronic databases were used to search for the published results of previous research: CINAHL, Medline Ovid, Scopus, the Web of Science, Academic Search Premiere, Eric, and the Cochrane Library. Search inclusion criteria were planned in the PICOS review format by including peer-reviewed articles published in any language between 2000 and 2014. Five peer-reviewed articles remained after the screening process. The results of the original studies were analysed using a thematic synthesis. The results indicate that a positive intercultural mentor enhanced reciprocal learning by improving the experience of international healthcare students and reducing stress in the clinical environment. Integrating international healthcare students into work with domestic students was seen to be important for reciprocal learning and the avoidance of discrimination. Many healthcare students were found to share similar experiences of mentoring and learning irrespective of their cultural background. However, the role of a positive intercultural mentor was found to make a significant difference for international students: such mentors advocated and mediated cultural differences and

    Research using large administrative databases has substantially increased in recent years. Accuracy with which comorbidities are represented in these databases has been questioned. The purpose of this study was to evaluate the extent of errors in obesity coding and its impact on arthroplasty research. Eighteen thousand thirty primary total knee arthroplasties (TKAs) and 10,475 total hip arthroplasties (THAs) performed at a single healthcare system from 2004-2014 were included. Patients were classified as obese or nonobese using 2 methods: (1) body mass index (BMI) ≥30 kg/m 2 and (2) international classification of disease, 9th edition codes. Length of stay, operative time, and 90-day complications were collected. Effect of obesity on various outcomes was analyzed separately for both BMI- and coding-based obesity. From 2004 to 2014, the prevalence of BMI-based obesity increased from 54% to 63% and 40% to 45% in TKA and THA, respectively. The prevalence of coding-based obesity increased from 15% to 28% and 8% to 17% in TKA and THA, respectively. Coding overestimated the growth of obesity in TKA and THA by 5.6 and 8.4 times, respectively. When obesity was defined by coding, obesity was falsely shown to be a significant risk factor for deep vein thrombosis (TKA), pulmonary embolism (THA), and longer hospital stay (TKA and THA). The growth in obesity observed in administrative databases may be an artifact because of improvements in coding over the years. Obesity defined by coding can overestimate the actual effect of obesity on complications after arthroplasty. Therefore, studies using large databases should be interpreted with caution, especially when variables prone to coding errors are involved. Copyright © 2017 Elsevier Inc. All rights reserved.

    There has been only limited evaluation of statistical methods for identifying safety risks of drug exposure in observational healthcare data. Simulations can support empirical evaluation, but have not been shown to adequately model the real-world phenomena that challenge observational analyses. To design and evaluate a probabilistic framework (OSIM2) for generating simulated observational healthcare data, and to use this data for evaluating the performance of methods in identifying associations between drug exposure and health outcomes of interest. Seven observational designs, including case-control, cohort, self-controlled case series, and self-controlled cohort design were applied to 399 drug-outcome scenarios in 6 simulated datasets with no effect and injected relative risks of 1.25, 1.5, 2, 4, and 10, respectively. Longitudinal data for 10 million simulated patients were generated using a model derived from an administrative claims database, with associated demographics, periods of drug exposure derived from pharmacy dispensings, and medical conditions derived from diagnoses on medical claims. Simulation validation was performed through descriptive comparison with real source data. Method performance was evaluated using Area Under ROC Curve (AUC), bias, and mean squared error. OSIM2 replicates prevalence and types of confounding observed in real claims data. When simulated data are injected with relative risks (RR) ≥ 2, all designs have good predictive accuracy (AUC > 0.90), but when RR < 2, no methods achieve 100 % predictions. Each method exhibits a different bias profile, which changes with the effect size. OSIM2 can support methodological research. Results from simulation suggest method operating characteristics are far from nominal properties.

    We present a framework for producing Cloudy photoionization models of the nebular emission from novae ejecta and storing a subset of the results in SQL database format for later usage. The database can be searched for models best fitting observed spectral line ratios. Additionally, the framework includes an optimization feature that can be used in tandem with the database to search for and improve on models by creating new Cloudy models while, varying the parameters. The database search and optimization can be used to explore the structures of nebulae by deriving their properties from the best-fit models. The goal is to provide the community with a large database of Cloudy photoionization models, generated from parameters reflecting conditions within novae ejecta, that can be easily fitted to observed spectral lines; either by directly accessing the database using the framework code or by usage of a website specifically made for this purpose.

    The objective of this systematic review was to synthesize the available qualitative evidence on the knowledge, attitudes and beliefs of adult patients, healthcare professionals and carers about oral dosage form modification. A systematic review and synthesis of qualitative studies was undertaken, utilising the thematic synthesis approach. The following databases were searched from inception to September 2015: PubMed, Medline (EBSCO), EMBASE, CINAHL, PsycINFO, Web of Science, ProQuest Databases, Scopus, Turning Research Into Practice (TRIP), Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Database of Systematic Reviews (CDSR). Citation tracking and searching the references lists of included studies was also undertaken. Grey literature was searched using the OpenGrey database, internet searching and personal knowledge. An updated search was undertaken in June 2016. Studies meeting the following criteria were eligible for inclusion; (i) used qualitative data collection and analysis methods; (ii) full-text was available in English; (iii) included adult patients who require oral dosage forms to be modified to meet their needs or; (iv) carers or healthcare professionals of patients who require oral dosage forms to be modified. Two reviewers independently appraised the quality of the included studies using the Critical Appraisal Skills Programme Checklist. A thematic synthesis was conducted and analytical themes were generated. Of 5455 records screened, seven studies were eligible for inclusion; three involved healthcare professionals and the remaining four studies involved patients. Four analytical themes emerged from the thematic synthesis: (i) patient-centred individuality and variability; (ii) communication; (iii) knowledge and uncertainty and; (iv) complexity. The variability of individual patient's requirements, poor communication practices and lack of knowledge about oral dosage form modification, when combined with the complex and multi

    To evaluate the implementation of a time-driven activity-based costing analysis at five community health facilities in Haiti. Together with stakeholders, the project team decided that health-care providers should enter start and end times of the patient encounter in every fifth patient's medical dossier. We trained one data collector per facility, who manually entered the time recordings and patient characteristics in a database and submitted the data to a cloud-based data warehouse each week. We calculated the capacity cost per minute for each resource used. An automated web-based platform multiplied reported time with capacity cost rate and provided the information to health-facilities administrators. Between March 2014 and June 2015, the project tracked the clinical services for 7162 outpatients. The cost of care for specific conditions varied widely across the five facilities, due to heterogeneity in staffing and resources. For example, the average cost of a first antenatal-care visit ranged from 6.87 United States dollars (US$) at a low-level facility to US$ 25.06 at a high-level facility. Within facilities, we observed similarly variation in costs, due to factors such as patient comorbidities, patient arrival time, stocking of supplies at facilities and type of visit. Time-driven activity-based costing can be implemented in low-resource settings to guide resource allocation decisions. However, the extent to which this information will drive observable changes at patient, provider and institutional levels depends on several contextual factors, including budget constraints, management, policies and the political economy in which the health system is situated.

    The number of astronomical observations is steadily growing, giving rise to the need of cataloguing the obtained results. There are a lot of databases, created to store different types of data and serve a variety of purposes, e. g. databases providing basic data for astronomical objects (SIMBAD Astronomical Database), databases devoted to one type of astronomical object (ATNF Pulsar Database) or to a set of values of the specific parameter (Lorimer 1995 - database of flux density measurements for 280 pulsars on the frequencies up to 1606 MHz), etc. We found that creating an online database of pulsar flux measurements, provided with facilities for plotting diagrams and histograms, calculating mean values for a chosen set of data, filtering parameter values and adding new measurements by the registered users, could be useful in further studies on pulsar spectra.

    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 objective of this study was to describe the epidemiology and financial burden of burn-associated hospitalizations for children younger than 18 years in the United States. Retrospective data analysis of pediatric burn-associated hospitalizations was done using the Healthcare Cost and Utilization Project Kids' Inpatient Database for 2000. An estimated 10,000 children younger than 18 years were hospitalized for burn-associated injuries in the United States in 2000. These children spent an estimated 66,200 days in the hospital with associated hospital charges equal to USD 211,772,700. Total charges and length of stay for pediatric burn-associated hospitalizations in the United States during 2000 were associated with degree of burn, percentage of total body surface area burned, child's age, region of the United States, hospital location, and hospital type. Children 2 years old or younger were more likely to be nonwhite, be hospitalized for burns, and burn their hands/wrists, compared with children 3 to 17 years of age. Male children in both age groups were more likely to be hospitalized for burns than female children. Children 2 years old or younger were more likely to be burned by hot liquids/vapors and contact with hot substances/objects, while children 3 to 17 years were more likely to be burned by fire/flames. This study is the first national study on healthcare resource utilization for pediatric burn-associated hospitalizations to utilize the KID database. Burns are a major source of pediatric morbidity and are associated with significant national healthcare resource utilization annually. Future burn prevention efforts should emphasize implementing passive injury prevention strategies, especially for young children who are nonwhite and live in low-income communities.

    Using all telemetry and observational meta-data, we created a searchable database of Herschel observation footprints. Data from the Herschel space observatory is freely available for everyone but no uniformly processed catalog of all observations has been published yet. As a first step, we unified the data model for all three Herschel instruments in all observation modes and compiled a database of sky coverage information. As opposed to methods using a pixellation of the sphere, in our database, sky coverage is stored in exact geometric form allowing for precise area calculations. Indexing of the footprints allows for very fast search among observations based on pointing, time, sky coverage overlap and meta-data. This enables us, for example, to find moving objects easily in Herschel fields. The database is accessible via a web site and also as a set of REST web service functions which makes it usable from program clients like Python or IDL scripts. Data is available in various formats including Virtual Observatory standards.

    This study explores the distribution of international, regional and national scientific output in health information and communication, indexed in the MEDLINE and LILACS databases, between 1996 and 2005. A selection of articles was based on the hierarchical structure of Information Science in MeSH vocabulary. Four specific domains were determined: health information, medical informatics, scientific communications on healthcare and healthcare communications. The variables analyzed were: most-covered subjects and journals, author affiliation and publication countries and languages, in both databases. The Information Science category is represented in nearly 5% of MEDLINE and LILACS articles. The four domains under analysis showed a relative annual increase in MEDLINE. The Medical Informatics domain showed the highest number of records in MEDLINE, representing about half of all indexed articles. The importance of Information Science as a whole is more visible in publications from developed countries and the findings indicate the predominance of the United States, with significant growth in scientific output from China and South Korea and, to a lesser extent, Brazil.

    2013-01-01

    Noncontact electrocardiogram (ECG) measurement technique has gained popularity these days owing to its noninvasive features and convenience in daily life use. This paper presents mobile cloud computing for a healthcare system where a noncontact ECG measurement method is employed to capture biomedical signals from users. Healthcare service is provided to continuously collect biomedical signals from multiple locations. To observe and analyze the ECG signals in real time, a mobile device is used as a mobile monitoring terminal. In addition, a personalized healthcare assistant is installed on the mobile device; several healthcare features such as health status summaries, medication QR code scanning, and reminders are integrated into the mobile application. Health data are being synchronized into the healthcare cloud computing service (Web server system and Web server dataset) to ensure a seamless healthcare monitoring system and anytime and anywhere coverage of network connection is available. Together with a Web page application, medical data are easily accessed by medical professionals or family members. Web page performance evaluation was conducted to ensure minimal Web server latency. The system demonstrates better availability of off-site and up-to-the-minute patient data, which can help detect health problems early and keep elderly patients out of the emergency room, thus providing a better and more comprehensive healthcare cloud computing service.

    Objectives We aimed to explore healthcare professionals’ experience of treating chronic non-malignant pain by conducting a qualitative evidence synthesis. Understanding this experience from the perspective of healthcare professionals will contribute to improvements in the provision of care. Design Qualitative evidence synthesis using meta-ethnography. We searched five electronic bibliographic databases from inception to November 2016. We included studies that explore healthcare professionals’ experience of treating adults with chronic non-malignant pain. We used the GRADE-CERQual framework to rate confidence in review findings. Results We screened the 954 abstracts and 184 full texts and included 77 published studies reporting the experiences of over 1551 international healthcare professionals including doctors, nurses and other health professionals. We abstracted six themes: (1) a sceptical cultural lens, (2) navigating juxtaposed models of medicine, (3) navigating the geography between patient and clinician, (4) challenge of dual advocacy, (5) personal costs and (6) the craft of pain management. We rated confidence in review findings as moderate to high. Conclusions This is the first qualitative evidence synthesis of healthcare professionals’ experiences of treating people with chronic non-malignant pain. We have presented a model that we developed to help healthcare professionals to understand, think about and modify their experiences of treating patients with chronic pain. Our findings highlight scepticism about chronic pain that might explain why patients feel they are not believed. Findings also indicate a dualism in the biopsychosocial model and the complexity of navigating therapeutic relationships. Our model may be transferable to other patient groups or situations.

    Objectives To investigate whether there is an association between differences in travel time/travel distance to healthcare services and patients' health outcomes and assimilate the methodologies used to measure this. Design Systematic Review. We searched MEDLINE, Embase, Web of Science, Transport database, HMIC and EBM Reviews for studies up to 7 September 2016. Studies were excluded that included children (including maternity), emergency medical travel or countries classed as being in the global south. Settings A wide range of settings within primary and secondary care (these were not restricted in the search). Results 108 studies met the inclusion criteria. The results were mixed. 77% of the included studies identified evidence of a distance decay association, whereby patients living further away from healthcare facilities they needed to attend had worse health outcomes (eg, survival rates, length of stay in hospital and non-attendance at follow-up) than those who lived closer. 6 of the studies identified the reverse (a distance bias effect) whereby patients living at a greater distance had better health outcomes. The remaining 19 studies found no relationship. There was a large variation in the data available to the studies on the patients' geographical locations and the healthcare facilities attended, and the methods used to calculate travel times and distances were not consistent across studies. Conclusions The review observed that a relationship between travelling further and having worse health outcomes cannot be ruled out and should be considered within the healthcare services location debate.

    The VitalPoll Telemedicine System (VTS) was designed and developed for wireless home healthcare. The aims of this study were: to design the architecture and communication methods for a telemedicine system; to implement a physiologic routing hub to collect data from different medical devices and sensors; and to evaluate the feasibility of this system for applications in wireless home healthcare. The VTS was built using Bluetooth wireless and Internet technologies with client/server architecture. Several medical devices, which acquire vital signs, such as real-time electrocardiogram signals, heart rate, body temperature, and activity (physical motion), were integrated into the VTS. Medical information and data were transmitted over short-range interface (USB, RS232), wireless communication, and the Internet. The medical results were stored in a database and presented using a web browser. The patient's vital signals can be collected, transmitted, and displayed in real time by the VTS. The experiments verified no data loss during Bluetooth and Internet communication. Bluetooth and the Internet provide enough bandwidth channels to tranmit these vital signs. The experimental results show that VTS may be suitable for a practical telemedicine system in home healthcare.

    Ontario, the most populous province in Canada, has a universal healthcare system that routinely collects health administrative data on its 13 million legal residents that is used for health research. Record linkage has become a vital tool for this research by enriching this data with the Immigration, Refugees and Citizenship Canada Permanent Resident (IRCC-PR) database and the Office of the Registrar General's Vital Statistics-Death (ORG-VSD) registry. Our objectives were to estimate linkage rates and compare characteristics of individuals in the linked versus unlinked files. We used both deterministic and probabilistic linkage methods to link the IRCC-PR database (1985-2012) and ORG-VSD registry (1990-2012) to the Ontario's Registered Persons Database. Linkage rates were estimated and standardized differences were used to assess differences in socio-demographic and other characteristics between the linked and unlinked records. The overall linkage rates for the IRCC-PR database and ORG-VSD registry were 86.4 and 96.2 %, respectively. The majority (68.2 %) of the record linkages in IRCC-PR were achieved after three deterministic passes, 18.2 % were linked probabilistically, and 13.6 % were unlinked. Similarly the majority (79.8 %) of the record linkages in the ORG-VSD were linked using deterministic record linkage, 16.3 % were linked after probabilistic and manual review, and 3.9 % were unlinked. Unlinked and linked files were similar for most characteristics, such as age and marital status for IRCC-PR and sex and most causes of death for ORG-VSD. However, lower linkage rates were observed among people born in East Asia (78 %) in the IRCC-PR database and certain causes of death in the ORG-VSD registry, namely perinatal conditions (61.3 %) and congenital anomalies (81.3 %). The linkages of immigration and vital statistics data to existing population-based healthcare data in Ontario, Canada will enable many novel cross-sectional and longitudinal studies to

    Research addressing value in healthcare requires a measure of cost. While there are many sources and types of cost data, each has strengths and weaknesses. Many researchers appear to create study-specific cost datasets, but the explanations of their costing methodologies are not always clear, causing their results to be difficult to interpret. Our solution, described in this paper, was to use widely accepted costing methodologies to create a service-level, standardized healthcare cost data warehouse from an institutional perspective that includes all professional and hospital-billed services for our patients. The warehouse is based on a National Institutes of Research-funded research infrastructure containing the linked health records and medical care administrative data of two healthcare providers and their affiliated hospitals. Since all patients are identified in the data warehouse, their costs can be linked to other systems and databases, such as electronic health records, tumor registries, and disease or treatment registries. We describe the two institutions' administrative source data; the reference files, which include Medicare fee schedules and cost reports; the process of creating standardized costs; and the warehouse structure. The costing algorithm can create inflation-adjusted standardized costs at the service line level for defined study cohorts on request. The resulting standardized costs contained in the data warehouse can be used to create detailed, bottom-up analyses of professional and facility costs of procedures, medical conditions, and patient care cycles without revealing business-sensitive information. After its creation, a standardized cost data warehouse is relatively easy to maintain and can be expanded to include data from other providers. Individual investigators who may not have sufficient knowledge about administrative data do not have to try to create their own standardized costs on a project-by-project basis because our data

    A quasiexperimental study was conducted to demonstrate which teaching modality, peer education or computer-based education, improves the utilization of the library electronic databases and thereby evidence-based knowledge at the point of care. No significant differences were found between the teaching modalities. However, the study identified the need to explore professional development teaching modalities outside the traditional classroom to support an evidence-based practice healthcare environment.

    Advances in wireless technology give pace to the rapid development of mobile applications. The coming mobile revolution will bring dramatic and fundamental changes to our daily life. It will influence the way we live, the way we do things, and the way we take care of our health. For the healthcare industry, mobile applications provide a new frontier in offering better care and services to patients, and a more flexible and mobile way of communicating with suppliers and patients. Mobile applications will provide important real time data for patients, physicians, insurers, and suppliers. In addition, it will revolutionalize the way information is managed in the healthcare industry and redefine the doctor - patient communication. This paper discusses different aspects of mobile healthcare. Specifically, it presents mobile applications in healthcare, and discusses possible challenges facing the development of mobile applications. Obstacles in developing mobile healthcare applications include mobile device limitations, wireless networking problems, infrastructure constraints, security concerns, and user distrust. Research issues in resolving or alleviating these problems are also discussed in the paper.

    In this study, we investigated the adoptability of software quality measures for healthcare process measurement. Quality measures of ISO/IEC 9126 are redefined from a process perspective to build a generic healthcare process quality measurement model. Case study research method is used, and the model is applied to a public hospital's Entry to Care process. After the application, weak and strong aspects of the process can be easily observed. Access audibility, fault removal, completeness of documentation, and machine utilization are weak aspects and these aspects are the candidates for process improvement. On the other hand, functional completeness, fault ratio, input validity checking, response time, and throughput time are the strong aspects of the process.

    The availability of big data in healthcare and the intensive development of data reuse and georeferencing have opened up perspectives for health spatial analysis. However, fine-scale spatial studies of ecological and medical databases are limited by the change of support problem and thus a lack of spatial unit interoperability. The use of spatial disaggregation methods to solve this problem introduces errors into the spatial estimations. Here, we present a generic, two-step method for merging medical and ecological databases that avoids the use of spatial disaggregation methods, while maximizing the spatial resolution. Firstly, a mapping table is created after one or more transition matrices have been defined. The latter link the spatial units of the original databases to the spatial units of the final database. Secondly, the mapping table is validated by (1) comparing the covariates contained in the two original databases, and (2) checking the spatial validity with a spatial continuity criterion and a spatial resolution index. We used our novel method to merge a medical database (the French national diagnosis-related group database, containing 5644 spatial units) with an ecological database (produced by the French National Institute of Statistics and Economic Studies, and containing with 36,594 spatial units). The mapping table yielded 5632 final spatial units. The mapping table's validity was evaluated by comparing the number of births in the medical database and the ecological databases in each final spatial unit. The median [interquartile range] relative difference was 2.3% [0; 5.7]. The spatial continuity criterion was low (2.4%), and the spatial resolution index was greater than for most French administrative areas. Our innovative approach improves interoperability between medical and ecological databases and facilitates fine-scale spatial analyses. We have shown that disaggregation models and large aggregation techniques are not necessarily the best ways to

    Background South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Objectives Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. Methods This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL) were searched for combinations of keywords including ‘healthcare workers’, ‘risky sexual behaviour’ and ‘HIV and AIDS’. Articles from a range of countries met inclusion and exclusion criteria. Results Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. Conclusion More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

    To quantify healthcare costs in patients with psoriasis overall and in psoriasis patient sub-groups, by level of disease severity, presence or absence of psoriatic arthritis, or use of biologics. Administrative data from Truven Health Analytics MarketScan Research Database were used to select adult patients with psoriasis from January 2009 to January 2014. The first psoriasis diagnosis was set as the index date. Patients were required to have ≥6 months of continuous enrollment with medical and pharmacy benefits pre-index and ≥12 months post-index. Patients were followed from index until the earliest of loss to follow-up or study end. All-cause healthcare costs and outpatient pharmacy costs were calculated for the overall psoriasis cohort and for the six different psoriasis patient sub-groups: (a) patients with moderate-to-severe disease and mild disease, (b) patients with psoriatic arthritis and those without, and (c) patients on biologics and those who are not. Costs are presented per-patient-per-year (PPPY) and by years 1, 2, 3, 4, and 5 of follow-up, expressed in 2014 US dollars. A total of 108,790 psoriasis patients were selected, with a mean age of 46.0 years (52.7% females). Average follow-up was 962 days. All-cause healthcare costs were $12,523 PPPY. Outpatient pharmacy costs accounted for 38.6% of total costs. All-cause healthcare costs were highest for patients on biologics ($29,832), then for patients with psoriatic arthritis ($23,427) and those with moderate-to-severe disease ($21,481). Overall, all-cause healthcare costs and outpatient pharmacy costs presented an upward trend over a 5-year period. Psoriasis is associated with significant economic burden, which increases over time as the disease progresses. Patients with moderate-to-severe psoriasis, those with psoriatic arthritis, or use of biologics contributes to higher healthcare costs. Psoriasis-related pharmacy expenditure is the largest driver of healthcare costs in patients with psoriasis.

  20. Building IT capability in health-care organizations.

    While computer technology has revolutionized industries such as banking and airlines, it has done little for health care so far. Most of the health-care organizations continue the early-computer-era practice of buying the latest technology without knowing how it might effectively be employed in achieving business goals. By investing merely in information technology (IT) rather than in IT capabilities they acquire IT components--primarily hardware, software, and vendor-provided services--which they do not understand and, as a result, are not capable of fully utilizing for achieving organizational objectives. In the absence of internal IT capabilities, health-care organizations have relied heavily on the fragmented IT vendor market in which vendors do not offer an open architecture, and are unwilling to offer electronic interfaces that would make their 'closed' systems compatible with those of other vendors. They are hamstrung as a result because they have implemented so many different technologies and databases that information stays in silos. Health systems can meet this challenge by developing internal IT capabilities that would allow them to seamlessly integrate clinical and business IT systems and develop innovative uses of IT. This paper develops a comprehensive conception of IT capability grounded in the resource-based theory of the firm as a remedy to the woes of IT investments in health care.

    Challenges exist regarding TB infection control and TB in hospital-based healthcare workers in South Africa. However, few studies report on TB in non-hospital based healthcare workers such as primary or community healthcare workers. Our objectives were to investigate the implementation of TB infection control measures at primary healthcare facilities, the smear positive TB incidence rate amongst primary healthcare workers and the association between TB infection control measures and all types of TB in healthcare workers. One hundred and thirty three primary healthcare facilities were visited in five provinces of South Africa in 2009. At each facility, a TB infection control audit and facility questionnaire were completed. The number of healthcare workers who had had TB during the past three years was obtained. The standardised incidence ratio of smear positive TB in primary healthcare workers indicated an incidence rate of more than double that of the general population. In a univariable logistic regression, the infection control audit score was significantly associated with reported cases of TB in healthcare workers (OR=1.04, 95%CI 1.01-1.08, p=0.02) as was the number of staff (OR=3.78, 95%CI 1.77-8.08). In the multivariable analysis, the number of staff remained significantly associated with TB in healthcare workers (OR=3.33, 95%CI 1.37-8.08). The high rate of TB in healthcare workers suggests a substantial nosocomial transmission risk, but the infection control audit tool which was used did not perform adequately as a measure of this risk. Infection control measures should be monitored by validated tools developed and tested locally. Different strategies, such as routine surveillance systems, could be used to evaluate the burden of TB in healthcare workers in order to calculate TB incidence, monitor trends and implement interventions to decrease occupational TB.

    Background Loss to follow-up (LTFU) in HIV-positive cohorts is an important surrogate for interrupted clinical care which can potentially influence the assessment of HIV disease status and outcomes. After preliminary evaluation of LTFU rates and patient characteristics, we evaluated the risk of mortality by LTFU status in a high resource setting. Methods Rates of LTFU were measured in the Australian HIV Observational Database for a range of patient characteristics. Multivariate repeated measures regression methods were used to identify determinants of LTFU. Mortality by LTFU status was ascertained using linkage to the National Death Index. Survival following combination antiretroviral therapy initiation was investigated using the Kaplan-Meier (KM) method and Cox proportional hazards models. Results Of 3,413 patients included in this analysis, 1,632 (47.8%) had at least one episode of LTFU after enrolment. Multivariate predictors of LTFU included viral load (VL)>10,000 copies/ml (Rate ratio (RR) 1.63 (95% confidence interval (CI):1.45–1.84) (ref ≤400)), time under follow-up (per year) (RR 1.03 (95% CI: 1.02–1.04)) and prior LTFU (per episode) (RR 1.15 (95% CI: 1.06–1.24)). KM curves for survival were similar by LTFU status (p=0.484). LTFU was not associated with mortality in Cox proportional hazards models (univariate hazard ratio (HR) 0.93 (95% CI: 0.69–1.26) and multivariate HR 1.04 (95% CI: 0.77–1.43)). Conclusions Increased risk of LTFU was identified amongst patients with potentially higher infectiousness. We did not find significant mortality risk associated with LTFU. This is consistent with timely re-engagement with treatment, possibly via high levels of unreported linkage to other health care providers. PMID:25377928

    Background Several stroke outcome and quality control projects have demonstrated the success in stroke care quality improvement through structured process. However, Chinese health-care systems are challenged with its overwhelming numbers of patients, limited resources, and large regional disparities. Aim To improve quality of stroke care to address regional disparities through process improvement. Method and design The Shanghai Stroke Service System (4S) is established as a regional network for stroke care quality improvement in the Shanghai metropolitan area. The 4S registry uses a web-based database that automatically extracts data from structured electronic medical records. Site-specific education and training program will be designed and administrated according to their baseline characteristics. Both acute reperfusion therapies including thrombectomy and thrombolysis in the acute phase and subsequent care were measured and monitored with feedback. Primary outcome is to evaluate the differences in quality metrics between baseline characteristics (including rate of thrombolysis in acute stroke and key performance indicators in secondary prevention) and post-intervention. Conclusions The 4S system is a regional stroke network that monitors the ongoing stroke care quality in Shanghai. This project will provide the opportunity to evaluate the spectrum of acute stroke care and design quality improvement processes for better stroke care. A regional stroke network model for quality improvement will be explored and might be expanded to other large cities in China. Clinical Trial Registration-URL http://www.clinicaltrials.gov .

    Objectives To analyze the implementation of Medicaid preferred drug lists (PDLs) in a number of states and determine its impact on quality of care and cost relative to other segments of healthcare. Methods We reviewed research and case studies found by searching library databases, primarily MEDLINE and EBSCOHost, and searching pertinent journals. Keywords initially included “drug lists,” “prior authorization,” “prior approval,” and “Medicaid.” We added terms such as “influence use of other healthcare services,” “quality of care,” and “overall economic impact.” We mainly used primary sources. Results Based on our literature review, we determined that there are a number of issues regarding Medicaid PDLs that need to be addressed. Some issues include: (a) the potential for PDLs to influence the utilization of other healthcare services, (b) criteria used by Medicaid for determining acceptance of drugs onto a PDL, (c)the effect of PDL implementation on compliance to new regimens, (d) the potential effects of restricting medication availability on quality of care, (e) administrative costs associated with PDLs, and (f) satisfaction rates among patients and medical providers. This review highlighted expected short-term cost savings with limited degree of compromised quality of PDL implementation, but raised the concern about the potential long-term decline in quality of care and overall economic impact. Conclusions The number of concerns raised indicates that further studies are warranted regarding both short-term cost benefits as well as potential long-term effects of Medicaid PDL implementation. Objective analysis of these effects is necessary to ensure cost-effectiveness and quality of care. PMID:18561515

    In Thailand, pharmaceutical care has been recently introduced to a tertiary hospital as an approach to improve adherence to tuberculosis (TB) treatment in addition to home visit and modified directly observed therapy (DOT). However, the economic impact of pharmaceutical care is not known. The aim of this study was to estimate healthcare resource uses and costs associated with pharmaceutical care compared with home visit and modified DOT in pulmonary TB patients in Thailand from a healthcare sector perspective inclusive of out-of-pocket expenditures. We conducted a retrospective study using data abstracted from the hospital billing database associated with pulmonary TB patients who began treatment between 2010 and 2013 in three hospitals in Thailand. We used generalized linear models to compare the costs by accounting for baseline characteristics. All costs were converted to international dollars (Intl$) RESULTS: The mean direct healthcare costs to the public payer were $519.96 (95%confidence interval [CI] 437.31-625.58) associated with pharmaceutical care, $1020.39 (95% CI 911.13-1154.11) for home visit, and $887.79 (95% CI 824.28-955.91) for modified DOT. The mean costs to patients were $175.45 (95% CI 130.26-230.48) for those receiving pharmaceutical care, $53.77 (95% CI 33.25-79.44) for home visit, and $49.33 (95% CI 34.03-69.30) for modified DOT. After adjustment for baseline characteristics, pharmaceutical care was associated with lower total direct costs compared with home visit (-$354.95; 95% CI -285.67 to -424.23) and modified DOT (-$264.61; 95% CI -198.76 to -330.46). After adjustment for baseline characteristics, pharmaceutical care was associated with lower direct costs compared with home visit and modified DOT.

    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.

    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.

    Alzheimer's disease (AD) is a neurodegenerative disorder incurring significant social and economic costs. This study uses a US administrative claims database to evaluate the effect of AD on direct healthcare costs and utilization, and to identify the most common reasons for AD patients' emergency room (ER) visits and inpatient admissions. Demographically matched cohorts age 65 and over with comprehensive medical and pharmacy claims from the 2003-2004 MEDSTAT MarketScan Medicare Supplemental and Coordination of Benefits (COB) Database were examined: 1) 25,109 individuals with an AD diagnosis or a filled prescription for an exclusively AD treatment; and 2) 75,327 matched controls. Illness burden for each person was measured using Diagnostic Cost Groups (DCGs), a comprehensive morbidity assessment system. Cost distributions and reasons for ER visits and inpatient admissions in 2004 were compared for both cohorts. Regression was used to quantify the marginal contribution of AD to health care costs and utilization, and the most common reasons for ER and inpatient admissions, using DCGs to control for overall illness burden. Compared with controls, the AD cohort had more co-morbid medical conditions, higher overall illness burden, and higher but less variable costs ($13,936 s. $10,369; Coefficient of variation = 181 vs. 324). Significant excess utilization was attributed to AD for inpatient services, pharmacy, ER visits, and home health care (all p < 0.05). In particular, AD patients were far more likely to be hospitalized for infections, pneumonia and falls (hip fracture, syncope, collapse). Patients with AD have significantly more co-morbid medical conditions and higher healthcare costs and utilization than demographically-matched Medicare beneficiaries. Even after adjusting for differences in co-morbidity, AD patients incur excess ER visits and inpatient admissions.

    Inappropriate prescribing is a known risk factor for adverse drug event occurrence in the elderly. In various countries, several studies have used insurance healthcare databases to estimate the national prevalence of potentially inappropriate medications (PIM) in the elderly, as defined by explicit PIM lists. Recently, a representative sample of the French National Insurance Healthcare database, known as the "Echantillon Généraliste des Bénéficiaires" (EGB), was created, making it possible to assess the quality of drug prescription in France. Our objective was to evaluate the prevalence and the regional distribution of PIM prescription in the elderly aged 75 years and over in France, using the French PIM list and the EGB database. The list of drugs reimbursed to patients aged 75 years and over from 1 March 2007 to 29 February 2008 was extracted from the EGB. Drugs were classified as inappropriate using the French PIM list. A PIM user was defined as a person receiving at least one PIM reimbursement during the study period. Interregion variability was estimated from logistic regression. In 53.6% (95% CI: 53.0-54.1) of the elderly aged 75 years and over, at least one PIM was given during the study period. The three main drug groups identified were cerebral vasodilators (19.4%), drugs with antimuscarinic properties (19.3%), and long half-life benzodiazepines (17.8%). There was an important disparity in PIM prescription among the French regions. In 14 out of 22 regions, the risk of PIM prescription was significantly elevated. This geographical variation differed for the different drug groups. PIM prescription in the elderly is a major and worrying problem in France. As in other countries, recent accessibility of the National Insurance Healthcare database makes it possible to create local indicators that the regional health agencies could use to manage public health policy in closer alignment to the needs of the patients within each French region.

    home settings, or nursing home and hospital wards, compared to no intervention, or usual practices. Educational intervention in one of these studies was embedded within a broader, quality improvement bundle. The other two individually randomised controlled trials explored the effectiveness of educational intervention, delivered in two formats, to nursing staff cohorts.Due to the heterogeneity of the studies identified, pooling was not appropriate and we have presented a narrative overview. We explored a number of comparisons (1) education versus no education (2) components of educational intervention in a number of combinations and (3) education delivered in different formats. There were three primary outcomes: change in healthcare professionals' knowledge, change in healthcare professionals' clinical behaviour and incidence of new pressure ulcers.We are uncertain whether there is a difference in health professionals' knowledge depending on whether they receive education or no education on pressure ulcer prevention (hospital group: mean difference (MD) 0.30, 95% confidence interval (CI) -1.00 to 1.60; 10 participants; nursing home group: MD 0.30, 95% CI -0.77 to 1.37; 10 participants). This was based on very low-certainty evidence from one study, which we downgraded for serious study limitations, indirectness and imprecision.We are uncertain whether there is a difference in pressure ulcer incidence with the following comparisons: training, monitoring and observation, versus monitoring and observation (risk ratio (RR) 0.63, 95% CI 0.37 to 1.05; 345 participants); training, monitoring and observation, versus observation alone (RR 1.21, 95% CI 0.60 to 2.43; 325 participants) or, monitoring and observation versus observation alone (RR 1.93, 95% CI 0.96 to 3.88; 232 participants).

    Conflict within interprofessional healthcare teams, when not effectively resolved, has been linked to detrimental consequences; however, effective conflict resolution has been shown to enhance team performance, increase patient safety, and improve patient outcomes. Alarmingly, knowledge of healthcare professionals' ability to resolve conflict has been limited, largely due to the challenges that arise when researchers attempt to observe a conflict occurring in real time. Research literature has identified three central components that seem to influence healthcare professional's perceived ability to resolve conflict: communication competence, problem-solving ability, and conflict resolution education and training. The purpose of this study was to investigate the impact of communication competence, problem-solving ability, and conflict resolution education and training on healthcare professionals' perceived ability to resolve conflicts. This study employed a cross-sectional survey design. Multiple regression analyses demonstrated that two of the three central components-conflict resolution education and training and communication competence-were found to be statistically significant predictors of healthcare professionals' perceived ability to resolve conflict. Implications include a call to action for clinicians and academicians to recognize the importance of communication competence and conflict resolution education and training as a vital area in interprofessional pre- and post-licensure education and collaborative practice.

    The current version of the androgen receptor (AR) gene mutations database is described. We have added (if available) data on the androgen binding phenotype of the mutant AR, the clinical phenotype of the affected persons, the family history and whether the pathogenicity of a mutation has been proven. Exonic mutations are now listed in 5'-->3' sequence regardless of type and single base pair changes are presented in codon context. Splice site and intronic mutations are listed separately. The database has allowed us to substantiate and amplify the observation of mutational hot spots within exons encoding the AR androgen binding domain. The database is available from EML (ftp://www.ebi.ac.uk/pub/databases/androgen) or as a Macintosh Filemaker file (MC33@musica.mcgill.ca).

    Objectives To compare H index scores for healthcare researchers returned by Google Scholar, Web of Science and Scopus databases, and to assess whether a researcher's age, country of institutional affiliation and physician status influences calculations. Subjects and Methods One hundred and ninety-five Nobel laureates in Physiology and Medicine from 1901 to 2009 were considered. Year of first and last publications, total publications and citation counts, and the H index for each laureate were calculated from each database. Cronbach's alpha statistics was used to measure the reliability of H index scores between the databases. Laureate characteristic influence on the H index was analysed using linear regression. Results There was no concordance between the databases when considering the number of publications and citations count per laureate. The H index was the most reliably calculated bibliometric across the three databases (Cronbach's alpha = 0.900). All databases returned significantly higher H index scores for younger laureates (p < 0.0001). Google Scholar and Web of Science returned significantly higher H index for physician laureates (p = 0.025 and p = 0.029, respectively). Country of institutional affiliation did not influence the H index in any database. Conclusion The H index appeared to be the most consistently calculated bibliometric between the databases for Nobel laureates in Physiology and Medicine. Researcher-specific characteristics constituted an important component of objective research assessment. The findings of this study call to question the choice of current and future academic performance databases. PMID:22964880

    Purpose The purpose of this research study was to obtain healthcare executives' perspectives on diversity in executive healthcare leadership. The study focused on identifying perspectives about diversity and its potential impact on the access of healthcare services by people of color. The study also identified perspectives about factors that influence the attainment of executive healthcare roles by people of color. Design/methodology/approach A convenience sample of healthcare executives was obtained. The executives identified themselves as belonging to one of two subgroups, White healthcare executives or executives of color. Participants were interviewed telephonically in a semi-structured format. The interviews were transcribed and entered into a qualitative software application. The data were codified and important themes were identified. Findings The majority of the study participants perceive that diversity of the executive healthcare leadership team is important. There were differences in perspective among the subgroups as it relates to solutions to improve access to healthcare by people of color. There were also differences in perspective among the subgroups, as it relates to explaining the underrepresentation of people of color in executive healthcare leadership roles. Research limitations/implications This research effort benefited from the subject matter expertise of 24 healthcare executives from two states. Expansion of the number of survey participants and broadening the geographical spread of where participants were located may have yielded more convergence and/or more divergence in perspectives about key topics. Practical implications The findings from this research study serve to add to the existing body of literature on diversity in executive healthcare leadership. The findings expand on the importance of key elements in contemporary literature such as diversity, cultural competency and perspectives about the need for representation of people of

    This survey provides an overview of the development of policies and strategies for quality improvement in European healthcare systems, by mapping quality improvement policies and strategies, progress in their implementation, and early indications of their impact. A survey of quality improvement policies and strategies in healthcare systems of the European Union was conducted in 2005 for the first phase of the Methods of Assessing Response to Quality Improvement Strategies (MARQuIS) project. The survey, completed by 68 key experts in quality improvement from 24 European Union member states, represents their views and accounts of quality improvement policies and strategies in their healthcare systems. There are substantial international and intra-national variations in the development of healthcare quality improvement. Legal requirements for quality improvement strategies are an important driver of progress, along with the activities of national governments and professional associations and societies. Patient and service user organisations appear to have less influence on quality improvement. Wide variation in voluntary and mandatory coverage of quality improvement policies and strategies across sectors can potentially lead to varying levels of progress in implementation. Many healthcare organisations lack basic infrastructure for quality improvement. Some convergence can be observed in policies on quality improvement in healthcare. Nevertheless, the growth of patient mobility across borders, along with the implications of free market provisions for the organisation and funding of healthcare systems in European Union member states, require policies for cooperation and learning transfer.

    The healthcare sector was one of the few sectors of the US economy that created new positions in spite of the recent economic downturn. Economic contractions are associated with worsening morbidity and mortality, declining private health insurance coverage, and budgetary pressure on public health programs. This study examines the causes of healthcare employment growth and workforce composition in the US and evaluates the labor market's impact on healthcare spending and health outcomes. Data are collected for 50 states and the District of Columbia from 1999-2009. Labor market and healthcare workforce data are obtained from the Bureau of Labor Statistics. Mortality and health status data are collected from the Centers for Disease Control and Prevention's Vital Statistics program and Behavioral Risk Factor Surveillance System. Healthcare spending data are derived from the Centers for Medicare and Medicaid Services. Dynamic panel data regression models, with instrumental variables, are used to examine the effect of the labor market on healthcare spending, morbidity, and mortality. Regression analysis is also performed to model the effects of healthcare spending on the healthcare workforce composition. All statistical tests are based on a two-sided [Formula: see text] significance of [Formula: see text] .05. Analyses are performed with STATA and SAS. The labor force participation rate shows a more robust effect on healthcare spending, morbidity, and mortality than the unemployment rate. Study results also show that declining labor force participation negatively impacts overall health status ([Formula: see text] .01), and mortality for males ([Formula: see text] .05) and females ([Formula: see text] .001), aged 16-64. Further, the Medicaid and Medicare spending share increases as labor force participation declines ([Formula: see text] .001); whereas, the private healthcare spending share decreases ([Formula: see text] .001).

      While there has been a growing body of literature on the impact of combat stressors and post-traumatic stress on military service members involved in current conflicts, there has been little available information that directly examines the impact of these on healthcare providers. Aims for this integrative review included: (1) identifying exposures, experiences and other factors influencing stress responses in military healthcare providers previously engaged in a war effort and (2) describing the incidence of post-traumatic stress and related mental health problems in this population. Using Cooper's integrative review method, relevant documents were collected and analysed using content categories and a coding scheme to assist with identifying and recording data for units of analysis. Literature searches (including all years to present) were conducted using keywords for stress reaction, for healthcare provider and for military war effort involvement. Literature was obtained using the Cumulative Index to Nursing and Allied Health Literature, the National Library of Medicine and the American Psychological Association databases. Evidence suggests that similar to military combatants, military healthcare provider exposure to life-threatening situations will increase the probability of adverse psychological disorders following these traumatic experiences. The presence of a strong sense of meaning and purpose, within a supportive environment appear to help mediate the impact of these dangerous and stressful events. Results of this review and other supporting literature indicate the need for a systematic approach to studying combat stress and post-traumatic stress in deployed healthcare providers. © 2011 Blackwell Publishing Ltd.

    The Navy Precision Optical Interferometer (NPOI) has been recording astronomical observations for nearly two decades, at this point with hundreds of thousands of individual observations recorded to date for a total data volume of many terabytes. To make maximum use of the NPOI data it is necessary to organize them in an easily searchable manner and be able to extract essential diagnostic information from the data to allow users to quickly gauge data quality and suitability for a specific science investigation. This sets the motivation for creating a comprehensive database of observation metadata as well as, at least, reduced data products. The NPOI database is implemented in MySQL using standard database tools and interfaces. The use of standard database tools allows us to focus on top-level database and interface implementation and take advantage of standard features such as backup, remote access, mirroring, and complex queries which would otherwise be time-consuming to implement. A website was created in order to give scientists a user friendly interface for searching the database. It allows the user to select various metadata to search for and also allows them to decide how and what results are displayed. This streamlines the searches, making it easier and quicker for scientists to find the information they are looking for. The website has multiple browser and device support. In this paper we present the design of the NPOI database and website, and give examples of its use.

    Static nature of performance reporting systems in health care sector has resulted in inconsistent, incomparable, time consuming, and static performance reports that are not able to transparently reflect a round picture of performance and effectively support healthcare managers' decision makings. So, the healthcare sector needs interactive performance management tools such as performance dashboards to measure, monitor, and manage performance more effectively. The aim of this article was to identify key issues that need to be addressed for developing high-quality performance dashboards in healthcare sector. A literature review was established to search electronic research databases, e-journals collections, and printed journals, books, dissertations, and theses for relevant articles. The search strategy interchangeably used the terms of "dashboard", "performance measurement system", and "executive information system" with the term of "design" combined with operator "AND".

    Studies assessing the quality of the German health-care system in an international comparison come to different results. Therefore, this review aims to investigate how the German health-care system is evaluated in comparison to other health-care systems by reviewing international publications. Results show starting points for ways to improve the German health-care system, to maintain and expand its strengths as well as to derive strategies for solving identified problems. A systematic review searching different databases [library catalogues, WorldCat (including MEDLINE and OAIster-search), German National Library, Google Scholar and others]. Search requests were addressed to English or German language publications for the time period 2000-2010 (an informal search was conducted in October 2011 for an update). Results of the identified studies were aggregated and main statements derived. In total, 13 publications assessing the German health-care system in an international comparison were identified. These comparisons are based on 377 measures. After aggregation, 244 substantially different indicators remained, which were dedicated to 14 categories. It became apparent that the German health-care system can be characterised by a high level of expenses, a well-developed health-care infrastructure as well as a high availability of personal and material resources. Outcome measures demonstrate heterogeneous results. It can be stated that, particularly in this field, there is potential for further improvement. The utilisation of health-care services is high, the access is mostly not regulated and out of pocket payments can pose a barrier for patients. Waiting times are not regarded as a major weakness. Although civic satisfaction seems to be acceptable, a large portion of the citizens calls for elementary modifications. Especially, more patient-centred health-care delivery should be addressed as well as management of information and the adoption of meaningful electronic

    Many regional programs of the countries educate asthmatic children and their families to manage healthcare data. This study aims to establish a Web-based self-management system, eAsthmaCare, to promote the electronic healthcare (e-Healthcare) services for the asthmatic children in Taiwan. The platform can perform real time online functionality based upon a five-tier infrastructure with mutually supportive components to acquire asthma diaries, quality of life assessments and health educations. We have designed five multi-disciplinary portions on the interactive interface functioned with the analytical diagrams: (1) online asthma diary, (2) remote asthma assessment, (3) instantaneous asthma alert, (4) diagrammatical clinic support, and (5) asthma health education. The Internet-based asthma diary and assessment program was developed for patients to process self-management healthcare at home. In addition, the online analytical charts can help healthcare professionals to evaluate multi-domain health information of patients immediately. eAsthmaCare was developed by Java™ Servlet/JSP technology upon Apache Tomcat™ web server and Oracle™ database. Forty-one voluntary asthmatic children (and their parents) were intervened to examine the proposed system. Seven domains of satisfiability assessment by using the system were applied for approving the development. The average scores were scaled in the acceptable range for each domain to ensure feasibility of the proposed system. The study revealed the details of system infrastructure and developed functions that can help asthmatic children in self-management for healthcare to enhance communications between patients and hospital professionals.

    Falls are a leading cause of occupational injury for workers in healthcare, yet the risk factors of falls in this sector are understudied. Falls resulting in workers' compensation for time-loss from work from 2004-2007 for healthcare workers in British Columbia (BC) were extracted from a standardised incident-reporting database. Productive hours were derived from payroll data for the denominator to produce injury rates; relative risks were derived through Poisson regression modelling. A total of 411 falls were accepted for time-loss compensation. Compared to registered nurses, facility support workers (risk ratio (95% CI) = 6.29 (4.56-8.69)) and community health workers (6.58 (3.76-11.50)) were at high risk for falls. Falls predominantly occurred outdoors, in patients' rooms and kitchens depending on occupation and sub-sector. Slippery surfaces due to icy conditions or liquid contaminants were a leading contributing factor. Falls were more frequent in the colder months (January-March). The risk of falls varies by nature of work, location and worker demographics. The findings of this research will be useful for developing evidence-based interventions. STATEMENT OF RELEVANCE: Falls are a major cause of occupational injury for healthcare workers. This study examined risk factors including occupation type, workplace design, work setting, work organisation and environmental conditions in a large healthcare worker population in BC, Canada. The findings of this research should contribute towards developing evidence-based interventions.

    Considering the importance of healthcare waste management, following the ratification of the Waste Management law in 2005 and the subsequent approval of its executive bylaw in 2006 and finally the healthcare waste management criteria passing by the parliament in 2008, a review on the status of healthcare waste management is needed to implement the mentioned law properly. In this retrospective study during six months period all public hospitals in Iran's capital city, Tehran, were selected to conduct the survey. Data collected through an expert-standardized questionnaire was analyzed by using SPSS software. The results of the current status of healthcare waste management in Tehran hospitals showed 5.6% of hospitals were ranked excellent, 50.7% good, 26.4% medium, and the 13.9% of hospitals were ranked weak and 3.5% ranked very poor. The findings showed that appropriate technologies should be used to have better disposal stage. As the ratified criteria were not fully observed by all the selected hospitals, training courses and comprehensive program conducting by each hospital could be enjoyed as practical tools to implement the all stages of healthcare waste management properly.

Significant improvements in health-risk status and increases in use of preventive and chronic disease management services were observed in the intervention group. Although total healthcare costs increased significantly, reductions in costs were significant for those who moved from higher- to the lowest-risk levels. The contrast differences in costs between reduced- and maintained-risk groups was also significant. Matched pair comparisons provided further evidence of program effects on observed reductions in costs and improvements in prevention, but not improvements in chronic disease management. Incorporating incentivized health management strategies in employer-sponsored health insurance benefit designs can serve as a useful

    To review international experience in order to inform Australian PHC workforce policy on the role of primary healthcare organisations (PHCOs/Medicare Locals) in PHC workforce planning. A NZ and UK study tour was conducted by the lead author, involving 29 key informant interviews with regard to PHCOs roles and the effect on PHC workforce planning. Interviews were audio-taped with consent, transcribed and analysed thematically. Emerging themes included: workforce planning is a complex, dynamic, iterative process and key criteria exist for doing workforce planning well; PHCOs lacked a PHC workforce policy framework to do workforce planning; PHCOs lacked authority, power and appropriate funding to do workforce planning; there is a need to align workforce planning with service planning; and a PHC Workforce Planning and Development Benchmarking Database is essential for local planning and evaluating workforce reforms. With the Australian government promoting the role of PHCOs in health system reform, reflections from abroad highlight the key action within PHC and PHCOs required to optimise PHC workforce planning.

    Displaying compassion, benevolence and respect, and preserving the dignity of patients are important for any healthcare professional to ensure the provision of high quality care and patient outcomes. This paper presents a structured search and thematic review of the research evidence relating to values-based recruitment within healthcare. Several different databases, journals and government reports were searched to retrieve studies relating to values-based recruitment published between 1998 and 2013, both in healthcare settings and other occupational contexts. There is limited published research related to values-based recruitment directly, so the available theoretical context of values is explored alongside an analysis of the impact of value congruence. The implications for the design of selection methods to measure values is explored beyond the scope of the initial literature search. Research suggests some selection methods may be appropriate for values-based recruitment, such as situational judgment tests (SJTs), structured interviews and multiple-mini interviews (MMIs). Personality tests were also identified as having the potential to compliment other methods (e.g. structured interviews), as part of a values-based recruitment agenda. Methods including personal statements, references and unstructured/'traditional' interviews were identified as inappropriate for values-based recruitment. Practical implications are discussed in the context of values-based recruitment in the healthcare context. Theoretical implications of our findings imply that prosocial implicit trait policies, which could be measured by selection tools such as SJTs and MMIs, may be linked to individuals' values via the behaviours individuals consider to be effective in given situations. Further research is required to state this conclusively however, and methods for values-based recruitment represent an exciting and relatively unchartered territory for further research.

    Healthcare and financial decision making among older persons has been previously associated with cognition, health and financial literacy, and risk aversion; however, the manner by which these resources support decision making remains unclear, as past studies have not systematically investigated the pathways linking these resources with decision making. In the current study, we use path analysis to examine the direct and indirect pathways linking age, education, cognition, literacy, and risk aversion with decision making. We also decomposed literacy into its subcomponents, conceptual knowledge and numeracy, in order to examine their associations with decision making. Participants were 937 community-based older adults without dementia from the Rush Memory and Aging Project who completed a battery of cognitive tests and assessments of healthcare and financial decision making, health and financial literacy, and risk aversion. Age and education exerted effects on decision making, but nearly two thirds of their effects were indirect, working mostly through cognition and literacy. Cognition exerted a strong direct effect on decision making and a robust indirect effect working primarily through literacy. Literacy also exerted a powerful direct effect on decision making, as did its subcomponents, conceptual knowledge and numeracy. The direct effect of risk aversion was comparatively weak. In addition to cognition, health and financial literacy emerged as independent and primary correlates of healthcare and financial decision making. These findings suggest specific actions that might be taken to optimize healthcare and financial decision making and, by extension, improve health and well-being in advanced age.

    Enabling Patient-Centred (PC) care in modern healthcare requires the flow of medical information with the patient between different healthcare providers as they follow the patient's treatment plan. However, PC care threatens the stability of the balance of information security in the support systems since legacy systems fall short of attaining a security balance when sharing their information due to compromises made between its availability, integrity, and confidentiality. Results show that the main reason for this is that information security implementation in discrete legacy systems focused mainly on information confidentiality and integrity leaving availability a challenge in collaboration. Through an empirical study using domain analysis, observations, and interviews, this paper identifies a need for six information security requirements in legacy systems to cope with this situation in order to attain the security balance in systems supporting PC care implementation in modern healthcare.

    Service Oriented Architecture (SOA) is increasingly adopted by many sectors, including healthcare. Due to the nature of healthcare systems there is a need to increase SOA adoption success rates as the non integrated nature of healthcare systems is responsible for medical errors that cause the loss of tens of thousands patients per year. Following our previous research [1] we propose that SOA governance is a critical success factor for SOA success in healthcare. Literature reports multiple SOA governance models that have limitations and they are confusing. In addition to this, there is a lack of healthcare specific SOA governance models. This highlights a literature void and thus the purpose of this paper is to proposed a healthcare specific SOA governance framework.

    Patients with systemic sclerosis (SSc) often develop interstitial lung disease (ILD) and/or pulmonary arterial hypertension (PAH). The effect of ILD and PAH on healthcare costs among patients with SSc is not well described. The objective of this analysis was to describe healthcare costs in patients with newly diagnosed SSc and SSc patients newly diagnosed with ILD and/or PAH in the United States. This retrospective cohort analysis was conducted in the Truven Health MarketScan Commercial and Medicare Supplemental healthcare claims databases from 2003 to 2014. Based on International Classification of Diseases-9-Clinical Modification diagnosis codes on medical claims, patients were classified into 3 groups: incident SSc, SSc with incident ILD (SSc-ILD), and SSc with incident PAH (SSc-PAH). Patients were required to have continuous enrollment for 5 years to measure all-cause healthcare costs. Costs (adjusted to US$) were reported overall and by service type and year following diagnosis. Because of the overlap between groups, statistical comparisons were not conducted. There were 1957 patients with incident SSc, 219 with incident SSc-ILD, and 108 patients with incident SSc-PAH. Average (mean ± SD) all-cause healthcare costs over followup were higher for patients with incident SSc-ILD ($191,107 ± $322,193) or patients with incident SSc-PAH ($254,425 ± $240,497), compared to patients with incident SSc ($101,839 ± $167,155). Average annual costs over the 5-year period ranged from $18,513 to $23,268 for patients with incident SSc, from $31,285 to $55,446 for patients with incident SSc-ILD, and from $44,454 to $63,320 for patients with incident SSc-PAH. Costs tended to be the highest in the fifth year of followup. Among patients with SSc, ILD and PAH can result in substantial increases in healthcare costs.

    The National Resource Center for Health Information Technology (NRC) was formed in the fall of 2004 as part of the Agency for Healthcare Research and Quality (AHRQ) health IT portfolio to support its grantees. One of the core functions of the NRC was to assist grantees in their evaluation efforts of Health IT. This manuscript highlights some common challenges experienced by health IT project teams at nonacademic institutions, including inappropriately scoped and resourced evaluation efforts, inappropriate choice of metrics, inadequate planning for data collection and analysis, and lack of consideration of qualitative methodologies. Many of these challenges can be avoided or overcome. The strategies adopted by various AHRQ grantees and the lessons learned from their projects should become part of the toolset for current and future implementers of health IT as the nation moves rapidly towards its widespread adoption.

  16. Postcrisis redevelopment of sustainable healthcare systems.

    Research and field experience have identified a global gap in postdisaster rebuilding of healthcare systems due to the current primary focus on returning devastated community infrastructures to predisaster conditions. Disasters, natural or man-made, present an opportunity for communities to rebuild, restructure, and redefine their predisaster states, creating more resilient and sustainable healthcare systems. A model for sustainable postdisaster healthcare rebuilding was developed by bridging identified gaps in the literature on the processes of developing healthcare systems postdisaster and utilizing evidence from the literature on postdisaster community reconstruction. The proposed model-the Sustainable Healthcare Redevelopment Model-is designed to guide communities through the process of recovery, and identifies four stages for rebuilding healthcare systems: (1) response, (2) recovery, (3) redevelopment, and (4) sustainable development. Implementing sustainable healthcare redevelopment involves a bottom-up approach, where community stakeholders have the ability to influence policy decisions. Relationships within internal government agencies and with public-private partnerships are necessary for successful recovery. The Sustainable Healthcare Redevelopment Model can serve as a guideline for delivery of healthcare services following disaster or conflict and use of crisis as a window of opportunity to improve the healthcare delivery system and incorporate resilience into the healthcare infrastructure.

  17. A decade of Rossi X-ray Timing Explorer Seyfert observations: An RXTE Seyfert spectral database

    With over forty years of X-ray observations, we should have a grasp on the X- ray nature of active galactic nuclei (AGN). The unification model of Antonucci and Miller (1985) offered a context for understanding observations by defining a "typical" AGN geometry, with observed spectral differences explained by line- of-sight effects. However, the emerging picture is that the central AGN is more complex than unification alone can describe. We explore the unified model with a systematic X-ray spectral study of bright Seyfert galaxies observed by the Rossi X-Ray Timing Explorer (RXTE) over its first 10 years. We develop a spectral-fit database of 821 time-resolved spectra from 39 Seyfert galaxies fitted to a model describing the effects of an X-ray power-law spectrum reprocessed and absorbed by material in the central AGN region. We observe a relationship between radio and X-ray properties for Seyfert 1s, with the spectral parameters differing between radio-loud and radio-quiet Seyfert 1s. We also find a complex relationship between the Fe K equivalent width ( EW ) and the power-law photon index (Gamma) for the Seyfert 1s, with a correlation for the radio-loud sources and an anti-correlation for the radio- quiet sources. These results can be explained if X-rays from the relativistic jet in radio-loud sources contribute significantly to the observed spectrum. We observe scatter in the EW-Gamma relationship for the Seyfert 2s, suggesting complex environments that unification alone cannot explain. We see a strong correlation between Gamma and the reflection fraction ( R ) in the Seyfert 1 and 2 samples, but modeling degeneracies are present, so this relationship cannot be trusted as instructive of the AGN physics. For the Seyfert 1 sample, we find an anticorrelation between EW and the 2 to 10 keV luminosity ( L x ), also known as the X-ray Baldwin effect. This may suggest that higher luminosity sources contain less material or may be due to a time-lag effect. We do not

  18. Community health workers: a bridge to healthcare for people who inject drugs.

    Although people who inject drugs (PWIDs) have increased healthcare needs, their poor access and utilisation of mainstream primary healthcare services is well documented. To address this situation, community health workers (CHWs) who have personal experience of drug injecting in addition to healthcare training or qualifications are sometimes utilised. However, the role peer workers play as members of clinical primary healthcare teams in Australia and how they manage the healthcare needs of PWID, has been poorly documented. A qualitative ethnomethodological approach was used to study the methods used by CHWs. Data was collected using participant observation of CHWs in a PWID-targeted primary healthcare centre. CHW healthcare consultations with PWID were audio-recorded and transcribed verbatim. Transcripts along with field notes were analysed using membership categorisation and conversation analysis techniques to reveal how CHWs' personal and professional experience shapes their healthcare interactions with PWID clients. CHWs' personal experience of injecting drug use is an asset they utilise along with their knowledge of clinical practice and service systems. It provides them with specialised knowledge and language--resources that they draw upon to build trust with clients and accomplish transparent, non-judgmental interactions that enable PWID clients to be active participants in the management of their healthcare. Existing literature often discusses these principles at a theoretical level. This study demonstrates how CHWs achieve them at a micro-level through the use of indexical language and displays of the membership categories 'PWID' and 'healthcare worker'. This research explicates how CHWs serve as an interface between PWID clients and conventional healthcare providers. CHWs deployment of IDU-specific language, membership knowledge, values and behaviours, enable them to interact in ways that foster transparent communication and client participation in

    There are more than 100,000 asylum seekers registered in Germany, who are granted limited access to health services. This study aims to provide a systematic overview of the empirical literature on the health status of and health-care provision to asylum seekers in Germany in order to consolidate knowledge, avoid scientific redundance, and identify research gaps. A systematic review and evidence mapping of empirical literature on the health status of and health-care provision to asylum seekers in Germany will be performed. We will apply a three-tiered search strategy: 1. search in databases (PubMed/MEDLINE, Web of Science, IBSS, Sociological Abstracts, Worldwide Political Science Abstracts, CINAHL, Sowiport, Social Sciences Citation Index, ASSIA, MedPilot, DNB), dissertation and theses databases, and the internet (Google); 2. screening references of included studies; 3. contacting authors and civil society organizations for grey literature. Included will be studies which report quantitative and/or qualitative data or review articles on asylum seekers in Germany, published in German or English language. Outcome measures will include physical, mental, or social well-being, and all aspects of health-care provision (access, availability, affordability, and quality). Search results will be screened for eligibility by screening titles, abstracts and full texts. Data extraction comprises information on study characteristics, research aims, and domains of health or health-care services analyzed. The quality of studies will be appraised and documented by appropriate assessment tools. A descriptive evidence map will be drawn by categorizing all included articles by research design and the health conditions and/or domains of health-care provision analyzed. The body of evidence will be evaluated, and a narrative evidence synthesis will be performed by means of a multi-level approach, whereby quantitative and qualitative evidence are analyzed as separate streams and the product
