Effect of interventions to reduce potentially inappropriate use of drugs in nursing homes: a systematic review of randomised controlled trials

PubMed Central

2011-01-01

Background Studies have shown that residents in nursing homes often are exposed to inappropriate medication. Particular concern has been raised about the consumption of psychoactive drugs, which are commonly prescribed for nursing home residents suffering from dementia. This review is an update of a Norwegian systematic review commissioned by the Norwegian Directorate of Health. The purpose of the review was to identify and summarise the effect of interventions aimed at reducing potentially inappropriate use or prescribing of drugs in nursing homes. Methods We searched for systematic reviews and randomised controlled trials in the Cochrane Library, MEDLINE, EMBASE, ISI Web of Knowledge, DARE and HTA, with the last update in April 2010. Two of the authors independently screened titles and abstracts for inclusion or exclusion. Data on interventions, participants, comparison intervention, and outcomes were extracted from the included studies. Risk of bias and quality of evidence were assessed using the Cochrane Risk of Bias Table and GRADE, respectively. Outcomes assessed were use of or prescribing of drugs (primary) and the health-related outcomes falls, physical limitation, hospitalisation and mortality (secondary). Results Due to heterogeneity in interventions and outcomes, we employed a narrative approach. Twenty randomised controlled trials were included from 1631 evaluated references. Ten studies tested different kinds of educational interventions while seven studies tested medication reviews by pharmacists. Only one study was found for each of the interventions geriatric care teams, early psychiatric intervening or activities for the residents combined with education of health care personnel. Several reviews were identified, but these either concerned elderly in general or did not satisfy all the requirements for systematic reviews. Conclusions Interventions using educational outreach, on-site education given alone or as part of an intervention package and

To evaluate the prescription of potentially inappropriate medications (PIM), using the Screening Tool of Older Persons' potentially inappropriate Prescriptions (STOPP) and Beers criteria, to disabled older people. One hundred and forty-one patients aged ≥65 years with Barthel scale scores ≤60 and a regular intake of medication for chronic diseases at Chung Shan Medical University Hospital from July to December 2012 were included, and their medical records were reviewed. Comprehensive patient information was extracted from the patients' medical notes. The STOPP and Beers 2012 criteria were used separately to identify PIM, and logistic regression analyses were performed to identify risk factors for PIM. The optimal cutoff for the number of medications prescribed for predicting PIM was estimated using the Youden index. Of the 141 patients, 94 (66.7%) and 94 (66.7%) had at least one PIM identified by the STOPP and Beers criteria, respectively. In multivariate analysis, PIM identified by the Beers criteria were associated with the prescription of multiple medications (p = 0.013) and the presence of psychiatric diseases (p < 0.001), whereas PIM identified by the STOPP criteria were only associated with the prescription of multiple medications (p = 0.008). The optimal cutoff for the number of medications prescribed for predicting PIM by using the STOPP or Beers criteria was 6. After adjustment for covariates, patients prescribed ≥6 medications had a significantly higher risk of PIM, identified using the STOPP or Beers criteria, compared to patients prescribed <6 medications (both p < 0.05). This study revealed a high frequency of PIM in disabled older patients with chronic diseases, particularly those prescribed ≥6 medications. © 2015 S. Karger AG, Basel.

There are concerns with inappropriate prescribing of medicines among dentists especially antimicrobials. It is more concerning if this increases resistance rates. This study aimed to address this by assessing patterns of drugs prescribed for outpatients attending a hospital dental clinic in Nigeria. The findings will be used to plan future interventions, particularly around antimicrobial prescribing, where there are concerns. Medical records of patients attending the dental clinic of a leading teaching hospital in Nigeria were evaluated. Patients referred for admission, without a prescription, or prescribed medicines without a documented diagnosis were excluded. Overall, 607 prescriptions were analysed, 314 (51.7%) were for females. Periodontal and gum diseases (414; 68.1%) were the most frequent diagnoses, followed by pulpitis (49; 8.2%), and dentoalveolar abscess (43; 7.1%). A total of 1798 medicines were prescribed for all patients with a mean of 3.0 ± 0.48 medicines per prescription. Antimicrobials (1178; 65.5%) and analgesics (620; 34.5%) were the two drug classes prescribed. Ascorbic acid and vitamin B complex were prescribed for 361 (59.5%) patients. Among antimicrobials, amoxicillin (564; 95.1%) either alone or combined with clavulanic acid was the most frequently prescribed, followed by metronidazole (561; 94.6%). Brand name prescribing was also appreciably higher than WHO recommendations. Polypharmacy, brand name prescriptions, and the frequent prescription of antimicrobials were common practices at the dental clinic of this teaching hospital in Nigeria. We suggest a review of the current standard treatment guidelines in Nigeria to guide dentists on current knowledge- and evidence-based treatment of common oral diseases.

The aim of this study was to estimate the prevalence of potentially inappropriate medication (PIM) in the elderly as indicated by Germany's recently published list (PRISCUS) and to assess factors independently associated with PIM prescribing, both overall and separately for therapeutic groups. Claims data analysis (Health Insurance Sample AOK Hesse/KV Hesse, 18.75% random sample of insurants from AOK Hesse, Germany) is used in the study. The study population is composed of 73,665 insurants >64 years of age continuously insured in the last quarter of 2009 and either continuously insured or deceased in 2010. Prevalence estimates are standardized to the population of Germany (31 December 2010). The variables age, sex, polypharmacy, hospital stay and nursing care are assessed for their independent association with general PIM prescription and among 11 therapeutic subgroups using multivariate logistic regression analysis. In 2010, 22.0% of the elderly received at least one PIM prescription (men: 18.3%, women: 24.8%). The highest PIM prevalence was observed for antidepressants (6.5%), antihypertensives (3.8%) and antiarrhythmic drugs (3.5%). Amitriptyline, tetrazepam, doxepin, acetyldigoxin, doxazosin and etoricoxib were the most frequently prescribed PIMs. Multivariate analyses indicate that women (OR 1.39; 95% CI: 1.34-1.44) and persons with extreme polypharmacy (≥10 vs. <5 drugs: OR 5.16; 95% CI: 4.87-5.47) were at higher risk for receiving a PRISCUS-PIM. Risk analysis for therapeutic groups shows divergent associations. PRISCUS-PIMs are widely used. Educational programs should focus on drugs with high treatment prevalence and call professionals' attention to those elderly patients who are at special risk for inappropriate medication.

In Germany a list was drawn up that included 83 potentially inappropriate drugs. The PRISCUS list published in 2010 was intended to highlight certain problems in the pharmakotherapy of elderly patients and serve as a support for improved medicine safety. Almost a third of the insurance portfolio of the HALLESCHE Krankenversicherung aged over 75 years takes drugs that are on the PRISCUS list. Benzodiazepine and Z-drugs are taken most frequently. The costs per insurant with potentially inappropriate medication are on average higher than for policyholders who do not take drugs on the PRISCUS list. The costs per insurant are rising, with an increase in the number of PRISCUS agents being taken as well. However, there is still no scientific proof that potentially inappropriate drugs lead to adverse drug events.

To describe the frequency of medication-related problems in older adults with human immunodeficiency virus (HIV) infection. Retrospective chart review. Community. HIV-positive individuals aged 60 and older and age- and sex-matched HIV-negative individuals. Total number of medications, potentially inappropriate medications (PIMs) according to the modified Beers Criteria, anticholinergic drug burden according to the Anticholinergic Risk Scale (ARS), and drug-drug interactions using the Lexi-Interact online drug interactions database. Of 89 HIV-positive participants, most were Caucasian (91%) and male (94%), with a median age of 64 (range 60-82). Common comorbidities included hyperlipidemia, hypertension, and depression. Participants were taking a median of 13 medications (range 2-38), of which only a median of four were antiretrovirals. At least one PIM was prescribed in 46 participants (52%). Sixty-two (70%) participants had at least one Category D (consider therapy modification) drug-drug interaction, and 10 (11%) had a Category X (avoid combination) interaction. One-third of these interactions were between two nonantiretroviral medications. Fifteen participants (17%) had an ARS score of 3 or greater. In contrast, HIV-negative participants were taking a median of six medications, 29% had at least one PIM, and 4% had an ARS score of 3 or greater (P < .05 for each comparison, except P = .07 for anticholinergic burden). HIV-positive older adults have a high frequency of medication-related problems, of which a large portion is due to medications used to treat comorbid diseases. These medication issues were substantially higher than HIV-negative participants. Attention to the principles of geriatric prescribing is needed as this population ages in order to minimize complications from multiple medication use. © Published 2014.

2016-12-01

Older people are more sensitive to drugs and adverse drug reactions than younger people because of age-related physiological changes such as impaired renal function. As people with dementia are particularly vulnerable to the effects of drugs, it is especially important to evaluate the dosages of renally cleared medications in this group. The aim of this study was to estimate the prevalence of impaired renal function and inappropriate prescriptions on the basis of renal function among older patients with dementia or cognitive impairment. The medical records of 428 patients aged ≥65 years who were admitted to two hospitals in northern Sweden were reviewed and renally cleared medications were identified. The Cockcroft-Gault equation was used to evaluate renal function. Doses were evaluated according to the Geriatric Dosage Handbook. Renal function was impaired (estimated glomerular filtration rate <60 ml/min) in 65.4 % of the study population. Impaired renal function was associated with increasing age. Among 547 prescriptions identified as renally cleared medications, 9.1 % were inappropriate based on the patient's renal function; 13.5 % of the 326 patients prescribed renally cleared medications had inappropriate prescriptions. Inappropriate prescriptions were more common among patients living in nursing homes. Impaired renal function is common and inappropriate prescription is prevalent among old people with cognitive impairment in northern Sweden. Continuous consideration of renal function is important when prescribing medications to this group.

A study of the amount of drug advertisements received by general practitioners and the amount of the drugs practitioners prescribed showed a strong correlation of 0·80. Analysis suggests that a straight line graphic relationship provides the best fit for the results obtained. Further analysis of the quantity of advertising in relation to the amount of prescribing revealed two groups of drugs: those which were relatively more and those which were relatively less often advertised in proportion to the number of prescriptions issued for them.

potentially inappropriate prescribing (PIP) is associated with adverse health effects in older patients. PIP comprises prescription of potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs). to estimate the prevalence of PIMs and PPOs among older patients in primary care. retrospective longitudinal study. routinely collected data of 182,000 patients of 49 general practitioners (GPs) gathered in the GPs' database of the Academic Medical Center of Amsterdam, the Netherlands. in each studied year, all patients who were aged 65 years and older at 1st January. the prevalence of patients with at least one PIM and patients with at least one PPO was measured in 8 subsequent years (2007-14) by application of the Screening Tool of Older Persons potentially inappropriate Prescriptions (STOPP)/Screening Tool to Alert doctors to Right Treatment (START) criteria. Multivariate logistic regression was used to evaluate trends in the prevalence of PIMs and PPOs over the years. on average, 4,537 patients were included per investigated year. The mean prevalence of ≥1 PIM was 34.7% (range 34.0-35.6%) and of ≥1 PPO 84.8% (range 77.4-90.6%). Examples were the prescription of salicylates without a proper indication and the absence of a therapeutically indicated vitamin D prescription. The prevalence of ≥1 PPOs showed a statistically significant decrease over the investigated years (OR 0.87, P < 0.001), whereas the prevalence of PIMs did not change significantly. this study underscores the need for more attention to medication prescribing to older patients. The prevalence of PIP among older patients in primary care is substantial and the prevalence of PIMs did not decrease over time. © The Author 2017.

Due to more comorbidities, polypharmacy is common in elderly patients and drug interactions are inevitable. It is also challenging to treat an elderly patient with a diagnosis of cancer. Prevalence and clinical impacts of drug interactions and using potentially inappropriate medications (PIMs) have been studied in geriatric patients. However, these are not well defined in oncology practice. The purpose of this study is to define the prevalence of PIMs and severe drug interactions (SDIs) in elderly cancer patients and investigate the factors associated with them. Patients more than 65 years of age in both inpatient and outpatient clinics were evaluated. Patient, disease characteristics, and medications used were collected by self reports and medical records. Drug interactions were checked with Lexicomp® and PIM was defined with 2012 update of Beers criteria. Severe drug interactions are defined with category D or X DIs. Logistic regression was used to compute odds ratios (ORs) and 95 % confidence intervals (CIs) for the association between SDIs, PIMs, and clinical parameters. Four hundered and forty-five elderly patients (286 outpatient, 159 inpatient), with a median age of 70 (65-89) were evaluated. SDIs were present in 156 (35.1 %) of patients, 81 (28.3 %), and 75 (47.2 %) for outpatient and inpatients, respectively (p < 0.001). PIMs were present in 117 (26.6 %) of the patients, 40 (14.2 %), and 77(48.4 %) for outpatient and inpatients, respectively (p < 0.001). In multivariate analysis; polypharmacy (≥5 drugs), inpatient status and diagnosis of lung cancer were associated with severe DIs. Polypharmacy, inpatient status, and bad performance score (ECOG 3-4) were associated with PIMs. Nearly one third of the elderly cancer patients are exposed to severe drug interactions and PIMs. Clinicians dealing with elderly cancer patients should be more cautious when prescribing/ planning drugs to this group of patients. More strategies should be developed in

The drug information literatures usually contains thousands of drugs, which much of them were rare or never prescribed by the physicians. It caused pharmacy students must learn thousands of drugs that will depleted resources and the study result was not effective. The aim of the study was to identify 200 items of drugs that mostly prescribed by the physicians in the pharmacies at Medan City. The study was a descriptive study that used a cross sectional survey methodology. The 200 items of drugs that mostly prescribed by the physician obtained from the pharmacies selected regarding to random sampling method. The study was conducted from August to September 2016. The 200 items of drugs that mostly prescribed by the physician resulted from 21.962 prescribed drugs item of 16.352 prescriptions of 100 pharmacies. The list revealed that the most prescribed drugs was amoxicilline (5.55 %), followed by dexamethasone (4.44%), mefenamic acid (3.73%), cetirizine (3.16%), and ciprofloxacine (2.97%). It shows that the antibiotic drug was the most prescribed drug by the physician in pharmacies at Medan City. Further studies are required to develop the study card from the list.

The aim of this study was to identify the factors that influence prescribing of new drugs among general practitioners, endocrinologists and psychiatrists. Four focus groups were conducted with GPs, endocrinologists and psychiatrists on sources of awareness and influences on prescribing of new drugs. Pharmaceutical companies were the most important source for becoming aware of new drugs. There were many influences on the decision to prescribe a new drug, the most important being efficacy, safety, cost and advantage over existing therapies. Endocrinologists placed greater emphasis on evidence from clinical trials and scientific conferences, and psychiatrists and GPs placed more weight on pharmaceutical representatives, colleagues and specialists. New drug prescribing occurs in a complex environment with many influences. Effective interventions to promote rational, safe and effective prescribing of new drugs will need to be cognisant of these factors.

Purpose Medication safety is a critical concern for older adults. Regional variation in potentially inappropriate prescribing practices may reflect important differences in health care quality. Therefore, the objectives of this study were to characterize prescribing quality variation among older adults across geographic region, and to compare prescribing quality across rural versus urban residence. Methods Cross-sectional study of 1,549,824 older adult veterans with regular Veterans Affairs (VA) primary care and medication use during fiscal year 2007. Prescribing quality was measured by 4 indicators of potentially inappropriate prescribing: Zhan criteria drugs to avoid, Fick criteria drugs to avoid, therapeutic duplication, and drug-drug interactions. Frequency differences across region and rural-urban residence were compared using adjusted odds-ratios. Findings Significant regional variation was observed for all indicators. Zhan criteria frequencies ranged from 13.2% in the Northeast to 21.2% in the South. Nationally, rural veterans had a significantly increased risk for inappropriate prescribing according to all quality indicators. However, regional analyses revealed this effect was limited to the South and Northeast, whereas rural residence was neutral in the Midwest and protective in the West. Conclusions Significant regional variation in prescribing quality was observed among older adult veterans, mirroring recent findings among Medicare beneficiaries. The association between rurality and prescribing quality is heterogeneous, and relying solely on national estimates may yield misleading conclusions. While we documented important variations in prescribing quality, the underlying factors driving these trends remain unknown, and they are a vital area for future research affecting older adults in both VA and non-VA health systems.

Dental prescribing in Wales and associated public health issues.

Dental prescribing data in Wales have not been studied in detail previously. The analysis of national data available from Health Solutions Wales showed that dental prescribing in Wales accounted for 9% of total antibacterial prescribing in primary care in 2008. Penicillin and metronidazole constituted the bulk of antibiotics prescribed by dentists. Since the publication of National Institute for Health and Clinical Excellence (NICE) guidance (March 2008) on prophylaxis against infective endocarditis, dental prescriptions for amoxicillin 3g sachets and clindamycin capsules have decreased. Dental prescriptions for fluoride preparations increased in number from 2007 to 2008. Dental prescribing of controlled drugs raises no concern. The figure for antibiotic prescribing in Wales is similar to that of England. Nevertheless, the figure seems a little high, indicating potential inappropriate prescribing behaviour among dentists. Antibiotic resistance is a major public health issue and many patients each year die from infections from bacterial strains that are resistant to one or more antibiotics. Inappropriate use of antibiotics is a major cause of antibiotic resistance and every effort should be made to reduce the number of inappropriate antibiotic prescriptions in dental practice.

Systems for identifying potentially inappropriate medications in older adults are not immediately transferrable to advanced dementia, where the management goal is palliation. The aim of the systematic review was to identify and synthesise published systems and make recommendations for identifying potentially inappropriate prescribing in advanced dementia. Studies were included if published in a peer-reviewed English language journal and concerned with identifying the appropriateness or otherwise of medications in advanced dementia or dementia and palliative care. The quality of each study was rated using the STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) checklist. Synthesis was narrative due to heterogeneity among designs and measures. Medline (OVID), CINAHL, the Cochrane Database of Systematic Reviews (2005 - August 2014) and AMED were searched in October 2014. Reference lists of relevant reviews and included articles were searched manually. Eight studies were included, all of which were scored a high quality using the STROBE checklist. Five studies used the same system developed by the Palliative Excellence in Alzheimer Care Efforts (PEACE) Program. One study used number of medications as an index, and two studies surveyed health professionals' opinions on appropriateness of specific medications in different clinical scenarios. Future research is needed to develop and validate systems with clinical utility for improving safety and quality of prescribing in advanced dementia. Systems should account for individual clinical context and distinguish between deprescribing and initiation of medications.

Pharmaceutical companies paid at least $3.91bn to prescribers in 2013, yet evidence indicating whether industry payments shift prescribing away from generics is limited. This study examined the association between amount of industry payments to prescribers and generic drug prescribing rates among Medicare Part D prescribers. A cross-sectional analysis was conducted among 770 095 Medicare Part D prescribers after linking the 2013 national Open Payments data with 2013 Medicare Provider Utilization and Payment data. The exposure variable was the categorized amount of total industry payments to prescribers (i.e., meals, travel, research, and ownership). The outcome was prescriber's annual generic drug prescribing rate. Multivariable generalized linear regression models were used to examine the association between the amount of industry payments and prescriber's annual generic drug prescribing rates, controlling for prescriber's demographic and practice characteristics. In this sample, over one-third (38.0%) of Medicare Part D prescribers received industry payments in 2013. The mean annual generic drug prescribing rate was highest among prescribers receiving no payments and lowest among those receiving more than $500 of industry payments (77.5% vs. 71.3%, respectively; p < 0.001). The receipt of industry payments was independently associated with prescribers' generic drug prescribing rate; higher payments corresponded with lower generic drug prescribing rates. Other prescriber characteristics associated with higher annual generic drug prescribing rate included male sex, non-northeast region, specialty, and patient volume. Receipt of industry payments was associated with a decreased rate of generic drug prescribing. How this affects patient care and total medical costs warrants further study.

Frail residents in the nursing home sector call for extra care in prescribing. The Norwegian General Practice Nursing Home (NORGEP-NH) list of 34 explicit criteria for potentially inappropriate medication use in nursing homes was developed explicitly for this population. The aim of this study was to employ the NORGEP-NH Criteria to study the extent of potentially inappropriate medication use among nursing home residents and explore possible associated factors. Cross-sectional observational pharmacoepidemiological study from residents in nursing homes in the county of Vestfold, Norway. Data collected 2009-11 included residents' demographic and clinical status and all medications, regular and on demand. 881 patients from 30 institutions (mean 85.9 years, 68.6% female), were included. According to NORGEP-NH, 43.8% were prescribed at least one potentially inappropriate regular medication, and 9.9% regularly received three or more potentially inappropriate medications. When also including a) the NORGEP-NH Deprescribing Criteria and b) including drugs prescribed for use as needed, 92.7% of all residents received medication that needs particular surveillance according to the NORGEP-NH. 69.7% of the nursing home residents used at least one psychotropic drug regularly. Female residents received more often than males at least one potentially inappropriate regular medication (OR 1.60, p=0.007). Regarding the prescription of three or more concomitant psychotropic medications, odds ratio for females was 1.79 (p=0.03) compared to males. Residents with the best performance in activities of daily living, and residents residing in long-term wards, had higher risk of using three or more psychotropic drugs. Use of multiple psychoactive drugs increased the risk of falls in the course of an acute episode of infection or dehydration (odds ratio 1.70, p=0.009). Prevalence of potentially inappropriate medications in nursing homes according to the NORGEP-NH was extensive, and especially

Few studies describe drug utilization in pregnancy focusing on prescribing practices. This study is part of a larger survey on perinatal care in the City of Rio de Janeiro, Brazil. The type of hospital (public, contracted out by the Unified National Health System, or private) determined the stratification of 10,072 hospitalized post-partum women, who were asked about medication used during pregnancy. Hospital records supplied information on drugs prescribed during labor. Drugs were classified according to the Anatomical Therapeutic Chemical (ATC) system. Another system was used for specific cases of referred use. A mean of 2.08 drugs was prescribed during labor, and a mean of 2.3 was reported during pregnancy. Anesthetics, antibiotics, oxytocin, and analgesics were the most frequently prescribed during labor, with significant differences between strata. Ferrous sulfate, vitamins, scopolamine, and acetaminophen were the main drugs reported during pregnancy. Women who had attempted abortion referred use of various kinds of tea (49.7%) and misoprostol (9.2%). The drug utilization pattern was consistent with the literature. This study offers knowledge on prescribing patterns during labor and self-reported use during pregnancy in both the public and private sectors.

Inappropriate drug donations: what has happened since the 1999 WHO guidelines?

Drug donations to developing countries may be part of medical relief operations in acute emergencies, development aid in non-emergency situations, or a corporate donations programme. After a number of documented inappropriate drug donations, the World Health Organization developed the 'Guidelines for Drug Donations', with the second and final version published in 1999. We reviewed the medical literature on drug donations since the Guidelines publication in 1999. Literature was retrieved from PubMed and other on-line databases as well as from relevant websites providing medical literature for use in developing countries. We considered the following donations to be inappropriate: (i) essential drugs in excessive quantities; (ii) mixed unused drugs (unsorted medicines and free samples); and (iii) drug dumping (large quantities of useless medicines). We retrieved 25 publications dated after 1999, including 20 and 5 from the scientific literature and 'grey' literature (technical reports, working papers), respectively. New information concerned emergencies in East Timor, Mozambique, El Salvador, Gujarat State (India), Aceh (Indonesia) and Sri Lanka. Except for East Timor and Gujarat, inappropriate donations still occurred, accounting for 85%, 37%, 70% and 80% of donations in Mozambique, El Salvador, Aceh and Sri Lanka, respectively. Very little information was found on drug donations in non-emergency situations. There are few recent reports on the compliance of drug donations with the World Health Organization guidelines. For emergency situations, there is still room for improvement. Drug donations in non-emergency situations need to be evaluated. A reform of drug donations policy is needed.

Previous studies of antihypertensive treatment of older patients have focused on blood pressure control, cardiovascular risk or adherence, whereas data on inappropriate antihypertensive prescriptions to older patients are scarce. The aim of the study was to assess inappropriate antihypertensive prescriptions to older patients. An observational, prospective multicentric study was conducted to assess potentially inappropriate prescription of antihypertensive drugs, in patients aged 75 years and older with arterial hypertension (HTN), in the month prior to hospital admission, using four instruments: Beers, Screening Tool of Older Person's Prescriptions (STOPP), Screening Tool to Alert Doctors to the Right Treatment (START) and Assessing Care of Vulnerable Elders 3 (ACOVE-3). Primary care and hospital electronic records were reviewed for HTN diagnoses, antihypertensive treatment and blood pressure readings. Of 672 patients, 532 (median age 85 years, 56% female) had HTN. 21.6% received antihypertensive monotherapy, 4.7% received no hypertensive treatment, and the remainder received a combination of antihypertensive therapies. The most frequently prescribed antihypertensive drugs were diuretics (53.5%), angiotensin-converting enzyme inhibitors (ACEIs) (41%), calcium antagonists (32.2%), angiotensin receptor blockers (29.7%) and beta-blockers (29.7%). Potentially inappropriate prescription was observed in 51.3% of patients (27.8% overprescription and 35% underprescription). The most frequent inappropriately prescribed drugs were calcium antagonists (overprescribed), ACEIs and beta-blockers (underprescribed). ACEI and beta-blocker underprescriptions were independently associated with heart failure admissions [beta-blockers odds ratio (OR) 0.53, 95% confidence interval (CI) 0.39-0.71, p < 0.001; ACEIs OR 0.50, 95% CI 0.36-0.70, p < 0.001]. Potentially inappropriate prescription was detected in more than half of patients receiving antihypertensive treatment

Based on changes in pharmacokinetics and -dynamics in elderly patients, there are potentially inappropriate medications (PIM) that should be avoided in patients aged ≥ 65 years. Current studies showed prescription rates of PIM between 22.5 and 28.4 % in the primary care setting. The evidence concerning reasons for PIM prescription by FPs is limited. This mixed method study consisted of three research parts: 1) semi-standardized content analysis of patients' records, 2) qualitative interviews with FPs using a) open questions and b) selected patient-specific case vignettes and 3) qualitative interviews with FPs' medical assistants. The integration of qualitative interviews was used to explain the quantitative results (triangulation design). PIM were identified according to the German PRISCUS list. Descriptive and multivariate statistical analysis was done using SPSS 22.0. Qualitative content analysis of interviews was used to classify the content of the interviews for indicating pertinent categories. All data were pseudonymously recorded and analyzed. Content analysis of 1846 patients' records and interviews with 7 related FPs were conducted. Elderly patients [n = 1241, mean age: 76, females: 56.6 %] were characterized in average by 8.3 documented chronic diagnosis. 23.9 % of elderly patients received at least one PIM prescription. Sedatives/hypnotics were the most frequent prescribed PIM-drugs (13.7 %). Mental disorders, gender and number of long-term medication were detected as predictors for the probability of a PIM prescription. Common reported reasons for PIM prescription by FPs concerned limited knowledge regarding PIM, limited applicability of PIM lists in daily practice, lack of time, having no alternatives in medication, stronger patient-related factors than age that influence prescription, own bad experiences regarding changes of medication or refusal of following prescriptions of sedative/hypnotics. It is essential to see FPs in a complex

computerised interventions have been suggested as an effective strategy to reduce potentially inappropriate prescribing (PIP) for hospitalised older adults. This systematic review and meta-analysis examined the evidence for efficacy of computerised interventions designed to reduce PIP in this patient group. an electronic literature search was conducted using eight databases up to October 2017. Included studies were controlled trials of computerised interventions aiming to reduce PIP in hospitalised older adults (≥65 years). Risk of bias was assessed using Cochrane's Effective Practice and Organisation of Care criteria. of 653 records identified, eight studies were included-two randomised controlled trials, two interrupted time series analysis studies and four controlled before-after studies. Included studies were mostly at a low risk of bias. Overall, seven studies showed either a statistically significant reduction in the proportion of patients prescribed a potentially inappropriate medicine (PIM) (absolute risk reduction {ARR} 1.3-30.1%), or in PIMs ordered (ARR 2-5.9%). However, there is insufficient evidence thus far to suggest that these interventions can routinely improve patient-related outcomes. It was only possible to include three studies in the meta-analysis-which demonstrated that intervention patients were less likely to be prescribed a PIM (odds ratio 0.6; 95% CI 0.38, 0.93). No computerised intervention targeting potential prescribing omissions (PPOs) was identified. this systematic review concludes that computerised interventions are capable of statistically significantly reducing PIMs in hospitalised older adults. Future interventions should strive to target both PIMs and PPOs, ideally demonstrating both cost-effectiveness data and clinically significant improvements in patient-related outcomes.

Increasing the use of generic medications could help control medical costs. However, educational interventions have limited impact on prescriber behavior, and e-prescribing alerts are associated with high override rates and alert fatigue. Our objective was to evaluate the effect of a less intrusive intervention, a redesign of an e-prescribing interface that provides default options intended to "nudge" prescribers towards prescribing generic drugs. This retrospective cohort study in an academic ambulatory multispecialty practice assessed the effects of customizing an e-prescribing interface to substitute generic equivalents for brand-name medications during order entry and allow a one-click override to order the brand-name medication. Among drugs with generic equivalents, the proportion of generic drugs prescribed more than doubled after the interface redesign, rising abruptly from 39.7% to 95.9% (a 56.2% increase; 95% confidence interval, 56.0-56.4%; P < .001). Before the redesign, generic drug prescribing rates varied by therapeutic class, with rates as low as 8.6% for genitourinary products and 15.7% for neuromuscular drugs. After the redesign, generic drug prescribing rates for all but four therapeutic classes were above 90%: endocrine drugs, neuromuscular drugs, nutritional products, and miscellaneous products. Changing the default option in an e-prescribing interface in an ambulatory care setting was followed by large and sustained increases in the proportion of generic drugs prescribed at the practice. Default options in health information technology exert a powerful effect on user behavior, an effect that can be leveraged to optimize decision making. © The Author 2016.

Many drugs require dose adjustment or are contraindicated in patients with chronic kidney disease (CKD) to avoid adverse events. The aims of this study were to assess if medication was appropriately dose adjusted in patients with CKD in primary care, to identify medications that were frequently prescribed inappropriately and to identify factors predicting mal-prescription. We conducted a cross-sectional observational study in 34 general practioners' offices, assessing the medication of patients with CKD stage ≥ 3 according to the corresponding pharmaceutical product information. Additional information was extracted from recommendations of scientific societies and regulatory authorities. Contraindicated and overdosed medications were identified. Predictive factors for inadequate prescribing were analyzed with multiple logistic regression. 589 patients (Ø 78 years, 63 % female) with CKD stage ≥ 3 were included. A total of 5102 medications were extracted from the medication sheets (94,6 % regular, 5,4 % "as needed"). 4,2 % were judged as being inadequate according to pharmaceutical information (2,1 % contraindicated, 2,1 % overdosed). 173 patients (29 %) had ≥ 1 inadequate prescription. The proportion of inadequate prescriptions fell to 3,5 % after adjustment for the most recent recommendations of scientific societies and regulatory authorities. Most frequent inappropriate prescriptions were ACE-inhibitors, diuretics, oral antidiabetic drugs, methotrexate and potassium supplements. Most important predictors for inadequate prescriptions were CKD stage ≥ 3b and number of medications. A quarter of all patients had a least one inadequate prescription. The overall proportion of inadequately prescribed drugs was low. Adjustment for recommendations by scientific societies and regulatory authorities further reduced the number of inadequate prescriptions. Valid data on the clinical relevance of inadequate prescriptions is scarce and further

The prescription of potentially inappropriate medications (PIMs) for older adults is a well-known population health concern. Updated country-specific estimates of inappropriate prescribing in older adults using germane explicit criteria are needed to facilitate physician-tailored quality improvement strategies. Therefore, we sought to determine the prevalence of PIMs for older adults in Emilia-Romagna, Italy, using the updated Maio criteria. We also evaluated patient and general practitioner (GP) characteristics related to inappropriate prescribing. Older adults (≥ 65) in 2012 were evaluated in a one-year retrospective study using administrative health care data. The 2011 Maio criteria includes 25 medications reimbursed by the Italian National Formulary, in the following categories in terms of severity: 16 medications that 'should always be avoided,' 3 that are 'rarely appropriate,' and 6 that have 'some indications although they are often misused.' To evaluate the extent of associations between patient and GP related characteristics, we used generalized estimating equations with an exchangeable covariance design to fit robust logistic regression models. A total of 865,354 older adults were in the cohort and 28% had at least one PIM. Of the entire cohort, 8%, 10%, and 14% of individuals were prescribed at least one medication that 'should always be avoided,' is 'rarely appropriate,' and has 'some indications but are often misused,' respectively. Older patients (≥ 75) and females were more likely to be exposed to PIMs. 2,923 GPs were identified in the region, each having prescribed at least one PIM, of which older GPs (≥ 56), male GPs, and solo practice GPs were more likely to prescribe PIMs to their older patients. The high prevalence of PIM exposure among older adults is a substantial issue in the region. Knowing how patient and GP characteristics relate to PIMs exposure may improve the design and targeting of initiatives for improving prescribing safety in

To assess Norwegian general practitioners' (GPs') level of potentially harmful drug prescribing for elderly patients. Prescription data for 12 months were retrospectively retrieved from the Norwegian Prescription Database (NorPD). Data were assessed in relation to 13 prescription quality indicators. General practice. A total of 454 GPs attending continuous medical education (CME) groups in Southern Norway, 85,836 patients >or=70 years who received any prescription from the GPs during the study period. Number of prescriptions assessed in relation to pharmacological inappropriateness based on a list of 13 explicit prescription quality indicators. Some 18.4% of the patients (66% females with mean age 79.8 years, 34% males with mean age 78.7 years) received one or more inappropriate prescriptions from their GP. An NSAID in a potentially harmful combination with another drug (7%) and a long-acting benzodiazepine (4.6%) were the most frequent inappropriate prescriptions made. Doctor characteristics associated with more inappropriate prescribing practice were old age and working single-handed with many elderly patients. The study reveals areas where GPs' prescribing practice for elderly patients can be improved and which can be targeted in educational interventions.

Patient adherence to prescribed antimicrobial drug dosing regimens.

2005-05-01

The aim of this article is to review current knowledge about the clinical impact of patients' variable adherence to prescribed anti-infective drug dosing regimens, with the aim of renewing interest and exploration of this important but largely neglected area of therapeutics. Central to the estimation of a patient's adherence to a prescribed drug regimen is a reliably compiled drug dosing history. Electronic monitoring methods have emerged as the virtual 'gold standard' for compiling drug dosing histories in ambulatory patients. Reliably compiled drug dosing histories are consistently downwardly skewed, with varying degrees of under-dosing. In particular, the consideration of time intervals between protease inhibitor doses has revealed that ambulatory patients' variable execution of prescribed dosing regimens is a leading source of variance in viral response. Such analyses reveal the need for a new discipline, called pharmionics, which is the study of how ambulatory patients use prescription drugs. Properly analysed, reliable data on the time-course of patients' actual intake of prescription drugs can eliminate a major source of unallocated variance in drug responses, including the non-response that occurs and is easily misinterpreted when a patient's complete non-execution of a prescribed drug regimen is unrecognized clinically. As such, reliable compilation of ambulatory patients' drug dosing histories has the promise of being a key step in reducing unallocated variance in drug response and in improving the informational yield of clinical trials. It is also the basis for sound, measurement-guided steps taken to improve a patient's execution of a prescribed dosing regimen.

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.

Antimicrobial agents are societal drugs: how should this influence prescribing?

Sarkar, Paul; Gould, Ian M

This paper is concerned with how those who prescribe antimicrobials should consider the wider repercussions of their actions. It is accepted that in an ecological system, pressure will cause evolution; this is also the case with antimicrobials, the result being the development of resistance and the therapeutic failure of drugs. To an extent, this can be ameliorated through advances by the pharmaceutical industry, but that should not stop us from critically appraising our use and modifying our behavior to slow this process down. Up to 50% of prescribing in human medicine and 80% in veterinary medicine and farming has been considered questionable. The Alliance for the Prudent Use of Antimicrobials (APUA) was approached by the WHO to review the situation. Their recommendations include decreasing the prescribing of antibacterials for nonbacterial infections. In the UK, there has been an initiative called "the path of least resistance". This encourages general practitioners to avoid prescribing or reduce the duration of prescriptions for conditions such as upper respiratory tract infections and uncomplicated urinary tract infections; this approach has been successful. Another recommendation is to reduce the prescribing of broad-spectrum antibacterials. In UK hospitals, the problems identified with the inappropriate use of antibacterials are insufficient training in infectious disease, difficulty in selecting empirical antibacterial therapy, poor use of available microbiological information, the fear of litigation and the fact that the majority of antibacterials are prescribed by the least experienced doctors. With close liaison between the laboratories and clinicians, and the development of local protocols, this can be addressed. Another recommendation is to tighten the use of antibacterial prophylaxis and to improve patient compliance. Through a combination of improved education for doctors and patients, and improved communication skills, these problems can be

To synthesise qualitative studies that explore prescribers' perceived barriers and enablers to minimising potentially inappropriate medications (PIMs) chronically prescribed in adults. A qualitative systematic review was undertaken by searching PubMed, EMBASE, Scopus, PsycINFO, CINAHL and INFORMIT from inception to March 2014, combined with an extensive manual search of reference lists and related citations. A quality checklist was used to assess the transparency of the reporting of included studies and the potential for bias. Thematic synthesis identified common subthemes and descriptive themes across studies from which an analytical construct was developed. Study characteristics were examined to explain differences in findings. All healthcare settings. Medical and non-medical prescribers of medicines to adults. Prescribers' perspectives on factors which shape their behaviour towards continuing or discontinuing PIMs in adults. 21 studies were included; most explored primary care physicians' perspectives on managing older, community-based adults. Barriers and enablers to minimising PIMs emerged within four analytical themes: problem awareness; inertia secondary to lower perceived value proposition for ceasing versus continuing PIMs; self-efficacy in regard to personal ability to alter prescribing; and feasibility of altering prescribing in routine care environments given external constraints. The first three themes are intrinsic to the prescriber (eg, beliefs, attitudes, knowledge, skills, behaviour) and the fourth is extrinsic (eg, patient, work setting, health system and cultural factors). The PIMs examined and practice setting influenced the themes reported. A multitude of highly interdependent factors shape prescribers' behaviour towards continuing or discontinuing PIMs. A full understanding of prescriber barriers and enablers to changing prescribing behaviour is critical to the development of targeted interventions aimed at deprescribing PIMs and reducing the

To determine whether drug samples are associated with physicians prescribing fewer generic, less costly medications. We conducted a retrospective study at a large university-affiliated internal medicine practice containing over 70 physicians. Using a pharmacy database, we identified all prescriptions written to uninsured or Medicaid patients that belonged to one of four classes of chronic medications. For the 9 months before and after the clinic closed its drug sample closet, we calculated the percentage of medications prescribed as generics and the mean cost of a 30-day supply of a prescription. Of 8911 prescriptions, 1973 met inclusion criteria. For uninsured patients, the percentage of medications prescribed as generics rose from 12% to 30% after the clinic closed its drug sample closet (P = 0.004). By consecutive three month periods, the percentage of prescribed generic medications rose steadily to a maximum of 40% (P < 0.001). For Medicaid patients, there was no significant change in generic prescribing (63% generic with samples versus 65% generic without samples, P = 0.42). Two factors were associated with generic prescribing in logistic regression: the absence of drug samples (OR 4.54, 95% CI 1.37-15.0) and the prescriber being an attending physician (OR 5.26, 95% CI 2.24-12.4). There was no statistically significant change in cost for either group. Physicians were three times more likely to prescribe generic medications to uninsured patients after drug samples were removed from the office. Drug samples may paradoxically lead to higher costs if physicians with access to samples prescribe more brand-name only drugs.

Benzodiazepines and sedative hypnotics are commonly used to treat insomnia and agitation in older adults despite significant risk. A clear understanding of the extent of the problem and its contributors is required to implement effective interventions. To determine the proportion of hospitalized older adults who are inappropriately prescribed benzodiazepines or sedative hypnotics, and to identify patient and prescriber factors associated with increased prescriptions. Single-center retrospective observational study. Urban academic medical center. Medical-surgical inpatients aged 65 or older who were newly prescribed a benzodiazepine or zopiclone. Our primary outcome was the proportion of patients who were prescribed a potentially inappropriate benzodiazepine or sedative hypnotic. Potentially inappropriate indications included new prescriptions for insomnia or agitation/anxiety. We used a multivariable random-intercept logistic regression model to identify patient- and prescriber-level variables that were associated with potentially inappropriate prescriptions. Of 1308 patients, 208 (15.9%) received a potentially inappropriate prescription. The majority of prescriptions, 254 (77.4%), were potentially inappropriate. Of these, most were prescribed for insomnia (222; 87.4%) and during overnight hours (159; 62.3%). Admission to a surgical or specialty service was associated with significantly increased odds of potentially inappropriate prescription compared to the general internal medicine service (odds ratio [OR], 6.61; 95% confidence interval [CI], 2.70-16.17). Prescription by an attending physician or fellow was associated with significantly fewer prescriptions compared to first-year trainees (OR, 0.28; 95% CI, 0.08-0.93). Nighttime prescriptions did not reach significance in initial bivariate analyses but were associated with increased odds of potentially inappropriate prescription in our regression model (OR, 4.48; 95% CI, 2.21-9.06).

Inappropriate prescribing in the elderly is common, but rates across different health care systems and the impact of formulary restrictions are not well described. To determine if rates of inappropriate medication use in the elderly differ between the Veterans Affairs (VA) health care system and the private sector Medicare health maintenance organization (HMO) patients. A cross-sectional study design compared administrative pharmacy claims from 10 distinct geographic regions in the United States in the VA health care system and 10 analogous regions for patients enrolled in Medicare HMOs. The cohorts included 123,633 VA and 157,517 Medicare HMO patients aged 65 years and older. Inappropriate medication use was identified using the Zhan modification of the Beers criteria, which categorizes 33 potentially inappropriate drugs into 3 major classifications: "always avoid," "rarely appropriate," and "some indications." Comparisons between the VA health care system and the private sector Medicare HMO were performed for overall differences and stratified by gender and age. The drug formulary status of the Zhan-criteria drugs was known for the VA health system but not for the Medicare HMO patients. Compared with private sector patients, VA patients were less likely to receive any inappropriate medication (21% vs. 29%, P <0.001), and in each classification: always avoid (2% vs. 5%, P <0.001), rarely appropriate (8% vs. 13%, P<0.001), and some indications (15% vs. 17%, P <0.001). The rate of inappropriate drug use was lower in the VA compared with the private sector for males (21% vs. 24%, P <0.001) and females (28% vs. 32%, P <0.001). Differences were consistent when stratified by age. Compared with private sector Medicare HMOs, elderly VA patients were less likely to receive medications defined by the Zhan criteria as potentially inappropriate. A restrictive formulary that excludes 12 of the 33 Zhan criteria drugs may be a factor in the reduction of undesired prescribing

Drug-drug interactions (DDIs) are common in clinical care and pose serious risks for patients. Electronic health records display DDI alerts that can influence prescribers, but the interface design of DDI alerts has largely been unstudied. In this study, the objective was to apply human factors engineering principles to alert design. It was hypothesized that redesigned DDI alerts would significantly improve prescribers' efficiency and reduce prescribing errors. In a counterbalanced, crossover study with prescribers, two DDI alert designs were evaluated. Department of Veterans Affairs (VA) prescribers were video recorded as they completed fictitious patient scenarios, which included DDI alerts of varying severity. Efficiency was measured from time-stamped recordings. Prescribing errors were evaluated against predefined criteria. Efficiency and prescribing errors were analyzed with the Wilcoxon signed-rank test. Other usability data were collected on the adequacy of alert content, prescribers' use of the DDI monograph, and alert navigation. Twenty prescribers completed patient scenarios for both designs. Prescribers resolved redesigned alerts in about half the time (redesign: 52 seconds versus original design: 97 seconds; p<.001). Prescribing errors were not significantly different between the two designs. Usability results indicate that DDI alerts might be enhanced by facilitating easier access to laboratory data and dosing information and by allowing prescribers to cancel either interacting medication directly from the alert. Results also suggest that neither design provided adequate information for decision making via the primary interface. Applying human factors principles to DDI alerts improved overall efficiency. Aspects of DDI alert design that could be further enhanced prior to implementation were also identified.

A previously identified communication behavior, online commentary, is physician talk that describes what he/she is seeing, feeling, or hearing during the physical examination of the patient. The investigators who identified this communication behavior hypothesized that its use may be associated with successful physician resistance to perceived or actual patient expectations for inappropriate antibiotic medication. This paper examines the relationship between actual and perceived parental expectations for antibiotics and physician use of online commentary as well as the relationship between online commentary use and the physician's prescribing decision. We conducted a prospective observational study in two private pediatric practices. Study procedures included a pre-visit parent survey, audiotaping of study consultations, and post-visit surveys of the participating physicians. Ten pediatricians participated (participation rate=77%) and 306 eligible parents participated (participation rate=86%) who were attending sick visits for their children with upper respiratory tract infections between October 1996 and March 1997. The main outcomes measured were the proportion of consultations with online commentary and the proportion of consultations where antibiotics were prescribed. Two primary types of online commentaries were observed: (1) online commentary suggestive of a problematic finding on physical examination that might require antibiotic treatment ('problem' online commentary), e.g., "That cough sounds very chesty"; and (2) online commentary that indicated the physical examination findings were not problematic and antibiotics were probably not necessary ('no problem' online commentary), e.g., "Her throat is only slightly red". For presumed viral cases where the physician thought the parent expected to receive antibiotics, if the physician used at least some 'problem' online commentary, he/she prescribed antibiotics in 91% (10/11) of cases. Conversely, when the

Government health funding (GHF) is a cosmopolitan problem. It is especially conspicuous in China, where drug sales become a main source of medical institutions' incomes due to limited GHF.

Abstract Government health funding (GHF) is a cosmopolitan problem. It is especially conspicuous in China, where drug sales become a main source of medical institutions’ incomes due to limited GHF. This is well known as China's “drug maintain medical institutions (DMMIs)” system which results directly in very high use of antibiotics, injections, and corticosteroids. However, few statistical data existed in China on the association between the GHF and the prevalence of inappropriate drug prescribing, despite widespread acknowledgment of its existence. A multistage sampling strategy was employed to select 442,100 prescriptions written between 2007 and 2011 by urban community health (CH) institutions and check the GHF in 36 key cities (districts) across China. This study examined the association between the GHF and the prevalence of inappropriate drug prescribing, which differs somewhat from previous studies. The data suggested that from 2007 to 2011, with the increase of GHF, prescribing behaviors (PB) gradually improved on the whole although doctors still prescribed a few more drugs than the recommendations from World Health Organization (WHO). This study found that there is significant negative association between GHF and main indicators of PB (correlation coefficients more than 0.5). The findings implied that government should further perfect the compensation mechanism to medical institutions for gradually weakening the compensation function of drug sales in medical institutions.

A Systematic Tool to Reduce Inappropriate Prescribing (STRIP), which includes the Screening Tool to Alert doctors to Right Treatment (START) and the Screening Tool of Older Peoples' Prescriptions (STOPP), has recently been developed in the Netherlands for older patients with polypharmacy in the general population. Active involvement of the patient is part of this systematic multidisciplinary medication review. Although annual review of pharmacotherapy is recommended for people with an intellectual disability (ID), a specific tool for this population is not yet available. Besides, active involvement can be compromised by ID. Therefore, the objective of this observational pilot study was to evaluate the process of medication review using STRIP in adults with an ID living in a centralized or dependent setting and the identification of drug-related problems using this tool. The study was performed in three residential care organizations for ID. In each organization nine clients with polypharmacy were selected by an investigator (a physician in training to become a specialized physician for individuals with an ID) for a review using STRIP. Clients as well as their legal representatives (usually a family member) and professional caregivers were invited to participate. Reviews were performed by an investigator together with a pharmacist. First, to evaluate the process time-investments of the investigator and the pharmacist were described. Besides, the proportion of reviews in which a client and/or his legal representative participated was calculated as well as the proportion of professional caregivers that participated. Second, to evaluate the identification of drug-related problems using STRIP, the proportion of clients with at least one drug-related problem was calculated. Mean time investment was 130minutes for the investigator and 90minutes for the pharmacist. The client and/or a legal representatives were present during 25 of 27 reviews (93%). All 27 professional

Patients with chronic kidney disease require appropriate adjustment of nephrotoxic and renally cleared medications to ensure safe and effective pharmacotherapy. It is currently unclear how often appropriate medication selection and dosage adjustment occurs in practice. Therefore, this study aimed to evaluate the extent of potentially inappropriate prescribing (PIP) (the use of a contraindicated medication or inappropriately high dose according to the renal function) in patients with renal impairment from admission through to discharge from the Royal Hobart Hospital (RHH), Tasmania, Australia; to evaluate the medications most commonly implicated in PIP; and the factors associated with PIP in renal impairment. Medical records of 251 patients consecutively admitted to the RHH aged 40 years and above, with a creatinine clearance of ≤60 mL/min, and hypertension and/or diabetes mellitus in their medical history, were reviewed. PIP was assessed using the Australian Medicines Handbook and/or product information. Of the 251 patients, 81 (32.3%) were receiving a total of 116 potentially inappropriate medications (PIMs) at the time of admission. The number of patients receiving PIMs (81 vs. 44, p<0.001 chi-square test) as well as the total number of PIMs (116 vs. 63, p<0.001 Wilcoxon signed rank test) were significantly decreased at discharge. Metformin was the most common PIM at admission. However, PIP of metformin was reduced by approximately 50% by discharge. Logistic regression analysis revealed two significant independent risk factors for PIP: a higher number of medications at admission increased risk of PIP (OR 1.1, 95% CI 1.02-1.18, p=0.010), and higher initial estimated glomerular filtration rate (eGFR) decreased the risk of PIP (OR 0.9, 95% CI 0.96-0.99, p=0.011). Despite the limitations of lack of body weight documentation and lack of clear guidelines for dosage adjustment based on the eGFR, PIP in patients with renal impairment is common and admission to the

Communication of an accurate and interpretable drug identifier between prescriber and pharmacist is critically important for realizing the potential benefits of electronic prescribing (e-prescribing) while minimizing its risk. The National Drug Code (NDC) is the most commonly used codified drug identifier in ambulatory care e-prescribing, but concerns have been raised regarding its use for this purpose.  To (a) assess the frequency of NDC identifier transmission in ambulatory e-prescribing; (b) characterize the type of NDC identifier transmitted (representative, repackaged, obsolete, private label, and unit dose); and (c) assess the level of agreement between drug descriptions corresponding to NDC identifiers in electronic prescriptions (e-prescriptions) and the free-text drug descriptions that were entered by prescribers.  We analyzed a sample of 49,997 e-prescriptions that were transmitted by ambulatory care prescribers to outlets of a national retail drugstore chain during a single day in April 2014. The First Databank MedKnowledge drug database was used as the primary reference data base to assess the frequency and types of NDC numbers in the e-prescription messages. The FDA's Comprehensive NDC Standard Product Labeling Data Elements File and the National Library of Medicine's RxNorm data file were used as secondary and tertiary references, respectively, to identify NDC numbers that could not be located in the primary reference file. Three experienced reviewers compared the free-text drug description that had been entered by the prescriber with the drug description corresponding to the NDC number from 1 of the 3 reference database files to identify discrepancies. Two licensed pharmacists with residency training and ambulatory care experience served as final adjudicators. A total of 42,602 e-prescriptions contained a value in the NDC field, of which 42,335 (84.71%) were found in 1 of the 3 study reference databases and were thus considered to be valid NDC

E-learning is an efficient and cost-effective educational method. This study aimed at evaluating the feasibility of an educational e-learning intervention, focused on teaching geriatric pharmacology and notions of comprehensive geriatric assessment, to improve drug prescribing to hospitalized elderly patients. Eight geriatric and internal medicine wards were randomized to intervention (e-learning educational program) or control. Clinicians of the two groups had to complete a specific per group e-learning program in 30 days. Then, ten patients (aged ≥75 years) had to be consecutively enrolled collecting clinical data at hospital admission, discharge, and 3 months later. The quality of prescription was evaluated comparing the prevalence of potentially inappropriate medications through Beer's criteria and of potential drug-drug interactions through a specific computerized database. The study feasibility was confirmed by the high percentage (90 %) of clinicians who completed the e-learning program, the recruitment, and follow-up of all planned patients. The intervention was well accepted by all participating clinicians who judged positively (a mean score of >3 points on a scale of 5 points: 0 = useless; 5 = most useful) the specific contents, the methodology applied, the clinical relevance and utility of e-learning contents and tools for the evaluation of the appropriateness of drug prescribing. The pilot study met all the requested goals. The main study is currently ongoing and is planned to finish on July 2015.

Older patients receiving home health care are particularly at risk of receiving potentially inappropriate medications compared to community-dwelling population. Data on appropriateness of prescribing in these patients is limited. To investigate the prevalence, patterns and determinants of potentially inappropriate medications among elderly patients receiving Home Health Care Services in Qatar. Home Health Care Services department in Hamad Medical Corporation-Qatar. A cross-sectional study, conducted over a 3 months period. Patients 65 years and older, taking at least one medication and receiving home care services were included. Potentially inappropriate medications were identified and classified in accordance with the American Geriatrics Society 2012 Beers Criteria. Prevalence of potentially inappropriate medications using updated Beers criteria. A total of 191 patients (38.2%) had at least one potentially inappropriate medication. As per Beers criteria, 35% of medications were classified as medications to be avoided in older adults regardless of conditions and 9% as potentially inappropriate medications when used with certain diseases or syndromes. The majority of potentially inappropriate medications (56%) were classified as medications to be used with caution. The two leading classes of potentially inappropriate medications were antipsychotics (27.4%) and selective serotonin reuptake inhibitors (16%). Significant predictors of inappropriate prescribing were hypertension [adjusted OR 1.7; 95% CI (1.0, 2.8)], dementia [adjusted OR 2.0; 95% CI (1.2, 3.1)], depression [adjusted OR 21.6; 95% CI (2.8, 168.4)], and taking more than ten prescribed medications [adjusted OR 1.9; 95% CI (1.3, 2.8)]. Prescribing potentially inappropriate medications is common among older adults receiving home health care services in Qatar, a finding that warrants further attention.

Outpatient prescription drugs continue to play an ever-increasing role in health care delivery in the United States. This paper focuses on the drugs prescribed by dentists and the patients who receive those drugs. The authors analyzed data from the 2001 Medical Expenditure Panel Survey (MEPS) for the U.S. community-based population. They developed estimates of the total market for prescription drugs related to a dental visit in terms of total number of prescriptions, total expenditures, and sources of payment. Also included are breakdowns by the type of dentist and the therapeutic class of drug prescribed. They also present a model that identifies the patient characteristics that best predict the likelihood of receiving a dental visit related prescription drug. Dental patients who were 18 years and older, African American patients, patients whose education level was less than a college degree, patients whose dental visit frequency was less than twice a year, and patients without medical insurance were most likely to report a prescription drug. Respondents' socioeconomic background and other demographic factors were related to the likelihood of receiving a prescription drug related to a dental visit. Patient age was related to the therapeutic class of the drug prescribed. Patients with fewer than two dental visits per year were more likely to report a dental prescription than patients with at least two visits per year.

Prescribing psychotropic drugs to adults with an intellectual disability

SUMMARY Mental illness is common in people with intellectual disability. They may also have physical health problems which can affect their mental state. Difficulties in communication can contribute to mental health problems being overlooked. These may present with changes in behaviour. Psychological management is usually preferable to prescribing psychotropic drugs. Behavioural approaches are the most appropriate way to manage challenging behaviour. If a drug is considered, prescribers should complete a thorough diagnostic assessment, exclude physical and environmental contributions to symptoms, and consider medical comorbidities before prescribing. Where possible avoid psychotropics with the highest cardiometabolic burden. Prescribe the minimum effective dose and treatment length, and regularly monitor drug efficacy and adverse effects. There is insufficient evidence to support the use of psychotropics for challenging behaviour. They should be avoided unless the behaviour is severe and non-responsive to other treatments.

Many doctors unnecessarily prescribe gastroprotective strategies to non-steroidal anti-inflammatory drugs users at low risk of non-steroidal anti-inflammatory drug-related gastrointestinal complications. To identify factors that predict the overuse of gastroprotective strategies in low-risk non-steroidal anti-inflammatory drug users. We distributed a questionnaire to family doctors and general internists consisting of a clinical vignette describing a low-risk hypothetical patient with osteoarthritis who was a candidate for non-steroidal anti-inflammatory drug therapy. Respondents were asked whether they would prescribe this patient a gastroprotective strategy and to estimate the annual risk of that patient developing a gastrointestinal complication with non-steroidal anti-inflammatory drug use. Respondents inappropriately recommending a gastroprotective strategy were compared with respondents who opted not to use gastroprotection. We received 340 responses (response rate of 28.3%), of which 278 supplied analysable data. Thirty-five percent of respondents inappropriately recommended a gastroprotective strategy for the low-risk subject. Inappropriate prescribers were significantly more likely to overestimate the risk of gastrointestinal complications with traditional non-steroidal anti-inflammatory drugs and this was strongly predictive of gastroprotective strategy recommendation in logistic regression. Many doctors inappropriately recommend gastroprotective strategies in low-risk non-steroidal anti-inflammatory drug users. Improving doctors' awareness of non-steroidal anti-inflammatory drug-associated gastrointestinal risks may lead to a decrease in inappropriate utilization of gastroprotective strategies in low-risk patients.

Direct-to-consumer advertising of COX-2 inhibitors: effect on appropriateness of prescribing.

2005-10-01

Spending on direct-to-consumer advertising (DTCA) of prescription drugs has increased dramatically in the past several years. An unresolved question is whether such advertising leads to inappropriate prescribing. In this study, the authors use survey and administrative data to determine the association of DTCA with the appropriate prescribing of cyclooxygenase-2 (COX-2) inhibitors for 1,382 patients. Treatment with either a COX-2 or a traditional nonsteroidal anti-inflammatory drug (NSAID) was defined as appropriate or not according to three different definitions of gastrointestinal risk. Patients who saw or heard a COX-2 advertisement and asked their physician about the advertised drug were significantly more likely to be prescribed a COX-2 (versus a NSAID, as recommended by evidence-based guidelines) than all other patients. Findings also suggest that some patients may benefit from DTCA. The authors discuss the need for balanced drug information for consumers, increased physician vigilance in prescribing appropriately, and further study of DTCA.

In this article we analyze the responses of 1220 Spanish physicians who participated in a survery about generic drugs. A previously validated questionnaire was sent to physicians through the Spanish Medical Councils of the different provinces. Four items were analyzed: what doctors know about generic drugs (knowledge); physicians' prescribing habits concerning these drugs (attitude and professional competence); how prescription of generic drugs effects pharmaceutical costs amd, finally, what doctors believe a generic drug should be. The influence of physician-related variables (age, type of contract, specialty, workload, etc.) on prescribing of generic drugs was also analyzed. In view of the results, we believe that to rationalize expenditure through and appropriate policy on generic drugs Spanish health authorities should offer more and better training and information (clear and independent) about what generic drugs are.

The study aims to develop a core set of pediatric drug-drug interaction (DDI) pairs for which electronic alerts should be presented to prescribers during the ordering process. A clinical decision support working group composed of Children's Hospital Association (CHA) members was developed. CHA Pharmacists and Chief Medical Information Officers participated. Consensus was reached on a core set of 19 DDI pairs that should be presented to pediatric prescribers during the order process. We have provided a core list of 19 high value drug pairs for electronic drug-drug interaction alerts to be recommended for inclusion as high value alerts in prescriber order entry software used with a pediatric patient population. We believe this list represents the most important pediatric drug interactions for practical implementation within computerized prescriber order entry systems.

A majority of doctor-patient meetings result in the patient getting a prescription. This underlines the need for a high-quality prescription process. While studies have been made on single therapeutic drug groups, a complete study of the physicians' general thought process that comprises the prescription of all drugs still remains to be made. To identify variations in ways of understanding drug prescribing among GPs. A descriptive qualitative study was conducted with 20 Swedish physicians. Informants were recruited purposively and their understandings about prescribing were studied in semi-structured interviews. Data were analysed using a phenomenographic approach. Five categories were identified as follows: (A) GP prescribed safe, reliable and well-documented drugs for obvious complaints; (B) GP sought to convince the patient of the most effective drug treatment; (C) GP chose the best drug treatment taking into consideration the patient's entire life situation; (D) GP used clinical judgement and close follow-up to minimize unnecessary drug prescribing and (E) GP prescribed drugs which are cheap for society and environmentally friendly. The categories are interrelated, but have different foci: the biomedical, the patient and the society. Each GP had more than one view but none included all five. The findings also indicate that complexity increases when a drug is prescribed for primary or secondary prevention. GPs understand prescribing differently despite similar external circumstances. The most significant factor to influence prescribing behaviour was the physician's patient relation approach. GPs may need to reflect on difficulties they face while prescribing to enhance their understandings.

The audit of drug prescribing pattern in under-five children is essential in identifying the various types of non-rational prescribing such as polypharmacy and irrational use of antimicrobials. The primary objective of this study was to determine the drug prescribing pattern for children aged below five years attending the paediatric outpatient clinic of a tertiary hospital in Ado-Ekiti, South-West Nigeria. A cross-sectional study was carried out using the medical records of patients who attended the paediatric clinic of the hospital between April 1 and October 30, 2013. The medical records of patients aged below five years were selected monthly for the period of the study using a regular interval ratio. Drug use indicators were assessed using the WHO guidelines on investigation of drug use in health care facilities. There were 293(55.7%) prescriptions collected from male patients and 233(44.3% from female patients with a total of 1369 prescribed drugs (2.6 ± 1.1 drugs per prescription). A total of three hundred and seventy-four (71.1%) patients had at least one antibiotic prescribed with antibiotics accounting for 28.2% of all drugs prescribed, while 13.5% of all encounters had an injection prescribed. Prescribing by generic name was done in 68.9 ± 26.5% of all prescribed medications, and 60.4% of all prescribed medications were from the latest version of the Nigerian Essential Drug List. Three hundred and twelve children (59.3%) had at least one anti-malarial drug prescribed while analgesics drugs accounted for 6.1% of all prescriptions. This study showed that over-prescription of antibiotics, significant use of injections and prescribing by generic name are real issues among Nigerian paediatric prescribers.

The Screening Tool of Older Persons' Potentially Inappropriate Prescriptions (stopp) criteria were updated in 2014 (stopp criteria ver.2), but few studies have evaluated the usefulness of stopp criteria in elderly patients. This prospective observational study evaluated the prevalence of potentially inappropriate medications (PIMs), and the efficacy of hospital pharmacists' assessment and intervention based on stopp criteria ver.2. The study was conducted at three medical units of Kobe University Hospital between April 2015 and March 2016. Pharmacists assessed and detected PIMs based on stopp criteria ver.2 and considered the patient's intention to change the prescription at the time of admission of each patient. If the pharmacists judged that benefits outweighed risks of prescription change and the patients consented to change the medications, they recommended the doctor to change the prescription. If there was a risk of exacerbation of disease by the change of medications and the pharmacists judged it to be difficult to adjust medications during hospitalization or the patients did not consent to change the medications, they did not recommend to change it. The pharmacists and the doctors discussed and finally decided whether to change the PIMs or not. The number of patients prescribed PIMs, the number and contents of PIMs, and the number of medications changed after pharmacists' intervention were calculated. Totally, 822 new inpatients aged ≥65 years prescribed ≥1 daily medicine were included. Their median (interquartile range) age was 75·0 (71·0-80·0) years, and 54·9% were male. According to the criteria, 346 patients (42·1%) were prescribed ≥1 PIMs. Patients prescribed PIMs took significantly more medications than others: 10·0 (7·0-13·0) vs. 6·0 (4·0-9·0), P < 0·001. The total number of PIMs was 651%, 47·6% of which (n = 310) were recommended the doctors to change, and 292 of 651 PIMs (44·9%) were finally discontinued/changed after

Ethinyl estradiol 0.03 mg/drospirenone 3 mg (EE/DRSP) contains a progestin drospirenone with antimineralocorticoid properties that may cause potassium retention leading to hyperkalemia. We estimated the percentage of EE/DRSP users prescribed concomitant potassium-sparing drugs [nonsteroidal antiinflammatory drugs, diuretics, angiotensin-converting enzyme inhibitors (with diuretics), angiotensin II agonists (with diuretics), and potassium chloride] between January 1, 2002, and March 31, 2005. We analyzed a population-based data set of 62,527 EE/DRSP users (Dimension Rx, Caremark). We compared the fill date and end date for each prescription (Rx) for an interacting drug to the start and end date for each EE/DRSP episode (linked Rxs). If a day of an interacting Rx overlapped with an EE/DRSP episode, concomitant prescribing was recorded. A total of 17.6% of the women concomitantly used EE/DRSP and an interacting drug. Twenty-nine percent of concomitant use occurred within a month of EE/DRSP initiation. Nonsteroidal antiinflammatory drugs and diuretics were most frequently used concomitantly with EE/DRSP. Forty percent of the women with concomitant use were 35 yearsof age or older at EE/DRSP initiation compared with 29% without concomitant use (p<.001). Obstetricians/gynecologists and family practitioners were the most common prescribers of EE/DRSP and potassium-sparing drugs, respectively. Concomitant prescribing of EE/DRSP and potassium-sparing drugs occurred frequently in our study population. As EE/DRSP becomes more widely used, physicians prescribing it should monitor patients for potassium-sparing drug use.

IMPORTANCE “Nudges” that influence decision making through subtle cognitive mechanisms have been shown to be highly effective in a wide range of applications, but there have been few experiments to improve clinical practice. OBJECTIVE To investigate the use of a behavioral “nudge” based on the principle of public commitment in encouraging the judicious use of antibiotics for acute respiratory infections (ARIs). DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial in 5 outpatient primary care clinics. A total of 954 adults had ARI visits during the study timeframe: 449 patients were treated by clinicians randomized to the posted commitment letter (335 in the baseline period, 114 in the intervention period); 505 patients were treated by clinicians randomized to standard practice control (384 baseline, 121 intervention). INTERVENTIONS The intervention consisted of displaying poster-sized commitment letters in examination rooms for 12 weeks. These letters, featuring clinician photographs and signatures, stated their commitment to avoid inappropriate antibiotic prescribing for ARIs. MAIN OUTCOMES AND MEASURES Antibiotic prescribing rates for antibiotic-inappropriate ARI diagnoses in baseline and intervention periods, adjusted for patient age, sex, and insurance status. RESULTS Baseline rates were 43.5% and 42.8% for control and poster, respectively. During the intervention period, inappropriate prescribing rates increased to 52.7% for controls but decreased to 33.7% in the posted commitment letter condition. Controlling for baseline prescribing rates, we found that the posted commitment letter resulted in a 19.7 absolute percentage reduction in inappropriate antibiotic prescribing rate relative to control (P = .02). There was no evidence of diagnostic coding shift, and rates of appropriate antibiotic prescriptions did not diminish over time. CONCLUSIONS AND RELEVANCE Displaying poster-sized commitment letters in examination rooms decreased inappropriate

Use of potentially inappropriate medications may result in increased morbidity, mortality and resource utilisation. Due to polypharmacy and age-related decline in renal function the elderly population is at particular risk. Therefore, the Beers Criteria include use of nonsteroidal anti-inflammatory drugs in chronic renal failure stage 4 and 5 as these drugs may worsen renal function. According to the summary of product characteristics, the nonsteroidal anti-inflammatory drugs ibuprofen and diclofenac are contraindicated in these patients. Objective was to assess the extent of nonsteroidal anti-inflammatory drug use in nursing homes with a focus on residents with severe renal failure. Multi-centre cross-sectional study in 21 German nursing homes. The study population comprised residents for whom at least one serum creatinine value and information about sex were available, so that creatinine clearance rate could be estimated. In all, 685 of 852 residents were included as they fulfilled the abovementioned criteria. Renal failure was severe (estimated creatinine clearance rate < 30 ml/min) in 106 residents (15.5 %). Approximately one-fifth was treated with at least one nonsteroidal anti-inflammatory drug in both the total study population (20.3 %) and that with severe renal failure (20.8 %). With one exception, all residents prescribed nonsteroidal anti-inflammatory drugs with severe renal failure were treated with at least one nonsteroidal anti-inflammatory drug that was contraindicated due to the underlying renal function. Notwithstanding their classification as potentially inappropriate medications and underlying contraindications, use of nonsteroidal anti-inflammatory drugs is common among nursing home residents with severe renal failure.

Objective There is limited evidence regarding the quality of prescribing for children in primary care. Several prescribing criteria (indicators) have been developed to assess the appropriateness of prescribing in older and middle-aged adults but few are relevant to children. The objective of this study was to develop a set of prescribing indicators that can be applied to prescribing or dispensing data sets to determine the prevalence of potentially inappropriate prescribing in children (PIPc) in primary care settings. Design Two-round modified Delphi consensus method. Setting Irish and UK general practice. Participants A project steering group consisting of academic and clinical general practitioners (GPs) and pharmacists was formed to develop a list of indicators from literature review and clinical expertise. 15 experts consisting of GPs, pharmacists and paediatricians from the Republic of Ireland and the UK formed the Delphi panel. Results 47 indicators were reviewed by the project steering group and 16 were presented to the Delphi panel. In the first round of this exercise, consensus was achieved on nine of these indicators. Of the remaining seven indicators, two were removed following review of expert panel comments and discussion of the project steering group. The second round of the Delphi process focused on the remaining five indicators, which were amended based on first round feedback. Three indicators were accepted following the second round of the Delphi process and the remaining two indicators were removed. The final list consisted of 12 indicators categorised by respiratory system (n=6), gastrointestinal system (n=2), neurological system (n=2) and dermatological system (n=2). Conclusions The PIPc indicators are a set of prescribing criteria developed for use in children in primary care in the absence of clinical information. The utility of these criteria will be tested in further studies using prescribing databases. PMID:27601499

Minimizing inappropriate medications in older populations: a 10-step conceptual framework.

2012-06-01

The increasing burden of harm resulting from the use of multiple drugs in older patient populations represents a major health problem in developed countries. Approximately 1 in 4 older patients admitted to hospitals are prescribed at least 1 inappropriate medication, and up to 20% of all inpatient deaths are attributable to potentially preventable adverse drug reactions. To minimize this drug-related iatrogenesis, we propose a quality use of medicine framework that comprises 10 sequential steps: 1) ascertain all current medications; 2) identify patients at high risk of or experiencing adverse drug reactions; 3) estimate life expectancy in high-risk patients; 4) define overall care goals in the context of life expectancy; 5) define and confirm current indications for ongoing treatment; 6) determine the time until benefit for disease-modifying medications; 7) estimate the magnitude of benefit versus harm in relation to each medication; 8) review the relative utility of different drugs; 9) identify drugs that may be discontinued; and 10) implement and monitor a drug minimization plan with ongoing reappraisal of drug utility and patient adherence by a single nominated clinician. The framework aims to reduce drug use in older patients to the minimum number of essential drugs, and its utility is demonstrated in reference to a hypothetic case study. Further studies are warranted in validating this framework as a means for assisting clinicians to make more appropriate prescribing decisions in at-risk older patients. Copyright © 2012 Elsevier Inc.

PURPOSE Little is known about the impact of recent restrictions on pharmaceutical industry detailing and sampling on prescribing behavior, particularly within smaller, independent practices. The objective of this study was to evaluate the effect of a policy prohibiting prescription drug samples and pharmaceutical industry interaction on prescribing patterns in a rural family practice clinic in central Oregon. METHODS Segmented linear regression models were used to evaluate trends in prescribing using locally obtained pharmacy claims. Oregon Medicaid pharmacy claims were used to control for secular prescribing changes. Total and class-specific monthly trends in branded, promoted, and average prescription drug costs were analyzed 18 months before and after policy implementation. RESULTS Aggregate trends of brand name drug use did not change significantly after policy implementation. In aggregate, use of promoted agents decreased by 1.43% while nonpromoted branded agents increased by 3.04%. Branded drugs prescribed for respiratory disease declined significantly by 11.34% compared with a control group of prescribers. Relative to the control group, prescriptions of promoted cholesterol-lowering drugs and antidepressants were reduced by approximately 9.98% and 11.34%, respectively. The trend in average cost per prescription for lipid-lowering drugs was significantly reduced by $0.70 per prescription per month. Overall, average prescription drug costs increased by $5.18 immediately after policy implementation. CONCLUSIONS Restriction of pharmaceutical industry representatives and samples from a rural family practice clinic produced modest reductions in branded drug use that varied by class. Although aggregate average costs increased, prescriptions for branded and promoted lipid-lowering agents and antidepressants were reduced. PMID:20843881

OBJECTIVE To evaluate the effects of a clinical pharmacist service on health-related quality of life (HRQL) and prescribing of drugs. METHODS A randomised controlled study was performed in two internal medicine wards. The intervention consisted of medication reviews with feedback to the physicians, drug treatment discussion with patients at discharge and medication reports. HRQL was evaluated at inclusion and after six months by self-rated global health (1: very poor; 5: very good) and by the EuroQol 5-dimension questionnaire (EQ-5D). Prescribing of drugs was analysed regarding three established drug-specific quality indicators (intervention and control patients) and potential drug-related problems (DRPs) during in-hospital care (intervention patients). RESULTS 345 patients (61% female; median age: 82) were analysed, 204 of whom (59%) completed the six-month HRQL follow-up. A total of 87 patients (53% of the intervention patients) received all parts of the intervention. Intention-to-treat analysis revealed no significant findings for any of the HRQL measures. Per-protocol analysis revealed significantly better HRQL in the intervention group at six-month follow-up as measured by global health (mean: 3.14 (SD: 0.87) vs 2.77 (0.94), p=0.020), but not as measured by summarised EQ-5D index (0.48 (0.36) vs 0.43 (0.37), p=0.57). The number of potentially inappropriate prescribings per patient according to the quality indicators (admission vs discharge) was 0.35 (0.73) versus 0.38 (0.72), p=0.47 (control patients), and 0.39 (0.83) versus 0.26 (0.56), p=0.039 (intervention patients who received the intervention). In the intervention group, 133 relevant potential DRPs were identified in 81 patients, 55 of which (41%) were acted upon by the attending physician. CONCLUSION A clinical pharmacist service during inpatient care may improve quality of prescribing and patients' HRQL. Trial registration clinicaltrials.gov Identifier: NCT01016301.

Financial incentives have been suggested to be effective in increasing the quality and efficiency of drug prescribing. Concern has been raised in relation to potential negative consequences on the quality of care. To describe and analyse the impact of an incentives model linking payment with adherence to drug and therapeutics committee (DTC) guidelines and self-reflection of prescribing pattern in a 'prescribing quality report'. The study was performed in the county of Stockholm, Sweden, with 139 (out of 154) primary healthcare centres (PHCs) participating in the project and 15 PHCs not participating. The study consisted of two parts: a quantitative observational study of prescribing patterns and a qualitative analysis of the submitted prescribing quality reports. All prescriptions issued from PHCs and dispensed at pharmacies during October to December 2005 and October to December 2006 were analysed, using adherence to the regional DTC guidelines as the main outcome measure. Adherence was assessed using the drug utilisation 90% methodology, i.e. focusing on drugs constituting 90% of the prescribed volume and the proportion of drugs included in the guidelines. The qualitative analysis focused on reports on the quality of drug prescribing submitted by each PHC in early 2007. The 139 PHCs participating in the programme accounted for 85% of all prescriptions issued in primary care during October to December 2006. Mean adherence to guidelines increased among participating practices by 3.3 percentage units (95% confidence interval (CI) 2.9-3.7%) to 83% (82.6-83.7%) during the year. The adherence among practices not participating increased by 3.1 percentage units (95% CI 1.7-4.4%) to 78.8% (95% CI 76.7-80.9%). The higher adherence achieved during the year corresponded to savings estimated at five times greater than the cost of running the programme including the financial incentives. In addition, many areas for improving prescribing were identified, such as limiting the

Searching online to buy commonly prescribed psychiatric drugs.

The use of online pharmacies to purchase prescription drugs is increasing. The patient experience when searching to buy commonly prescribed psychiatric drugs was investigated. Using the search term "buy [drug name] online" in Google, 38 frequently prescribed drugs, including 13 with a high potential for abuse, were searched by brand and generic names. The first page of results were analyzed, including with pharmacy certification checkers and ICANN WHOIS. Search results for all drugs yielded 167 pharmacies, of which 147 (88%) did not require a prescription. Considering all searches, the average number of pharmacies requiring a prescription was 2.7 for a brand name drug and 2.4 for a generic name. A phrase like "buy without a prescription" usually appeared on the search results page. All results for drugs with a high potential for abuse were for illegal pharmacies. Information from certification agencies was often conflicting. Most pharmacies were registered internationally. Patients searching online to purchase prescription psychiatric drugs are presented predominantly with illegal pharmacies, and find conflicting certification data. Patient education should address typical search results. Societal pressures may increase the use of online pharmacies including prescription drug costs, stigma, loss of trust in expert opinion, and the changing patient role. Copyright © 2017 Elsevier B.V.

The inappropriate use of drugs due to irrational prescriptions is a common problem in Iran, but there is little evidence of prescription patterns in rural family physicians. This study aimed to explore the prescribing pattern and rational drug use indicators for family physicians using Index of Rational Drug Prescribing (IRDP) in Kermanshah Province, Iran. In this retrospective study, 352,399 prescriptions from 184 family physicians in 103 primary health care (PHC) centers were examined. As stated, an analysis was done for rational use indicators suggested by World Health Organization (WHO): e.g., the percentage of prescriptions containing antibiotics, injections, and those prescribed by a generic name and from a national essential medicine list, plus the average number of drugs per prescription; these factors were all taken into account. Rational drug use was studied with the IRDP. The average number of drugs per prescription was 3.14 (± 1.2) and the average cost per prescription was 116,740 IRR (USD 3.6). Around 19% of prescriptions had more than four drugs, while the percentage of prescriptions involving antibiotics and injections was 52.1% and 24.4%, respectively. There was 95.1% drugs prescribed by their generic name and 95.9% were retrieved from the essential drugs list. The value of the IRDP was 3.70 out of 5. The findings of this study showed that some degree of irrational drug prescribing exists among family physicians, especially in terms of injections, antibiotics, and polypharmacy. It is recommended that there be continuing education programs for physicians regarding rational prescribing for different kinds of medical indications. Clinical practice guidelines should also assist with the rational use of medicine.

Electronic prescribing has benefited from computerised clinical decision support systems (CDSSs); however, no published studies have evaluated the potential for a CDSS to support GPs in prescribing specialist drugs. To identify potential weaknesses and errors in the existing process of prescribing specialist drugs that could be addressed in the development of a CDSS. Semi-structured interviews with key informants followed by an observational study involving GPs in the UK. Twelve key informants were interviewed to investigate the use of CDSSs in the UK. Nine GPs were observed while performing case scenarios depicting requests from hospitals or patients to prescribe a specialist drug. Activity diagrams, hierarchical task analysis, and systematic human error reduction and prediction approach analyses were performed. The current process of prescribing specialist drugs by GPs is prone to error. Errors of omission due to lack of information were the most common errors, which could potentially result in a GP prescribing a specialist drug that should only be prescribed in hospitals, or prescribing a specialist drug without reference to a shared care protocol. Half of all possible errors in the prescribing process had a high probability of occurrence. A CDSS supporting GPs during the process of prescribing specialist drugs is needed. This could, first, support the decision making of whether or not to undertake prescribing, and, second, provide drug-specific parameters linked to shared care protocols, which could reduce the errors identified and increase patient safety. © British Journal of General Practice 2017.

Clinical decision support provided by drug information centers is an intervention that can ensure rational drug therapy for pregnant women. We have examined whether physicians' teratogenic risk perceptions and confidence in prescribing drugs to pregnant women is altered after advice from the Norwegian drug information centers, Regional Medicines and Pharmacovigilance Centres i Norway (RELIS). Physicians who consulted RELIS for advice on patient-specific drug use in pregnancy from November 2013 to April 2014 completed questionnaires before and after receiving the advice. A scale from 1 to 7 was used to rate confidence in prescribing and perception of teratogenic risk. The lower part of the scale represented a low perception of teratogenic risk and a high confidence in prescribing a drug in pregnancy. The data were analyzed using a mixed linear model. A total of 45 physicians participated in the study and they assessed 64 drugs or categories of drugs. Advice from RELIS increased confidence in prescribing, with a statistically significant mean change on the scale from 4.1 to 2.9. The assessment of teratogenic risk was reduced after advice from RELIS, with a mean change from 3.2 to 2.5, though this was not significant. A subgroup of 26 physicians completed questionnaires both before and after advice from RELIS and assessed a total of 32 drugs or categories of drugs. In 94% of these assessments, advice from RELIS altered the physician's confidence in prescribing. Perception of teratogenic risk was altered in 78% of the assessments. Our results show that physicians' perception of teratogenic risk and confidence in prescribing drugs to pregnant women is influenced by advice from Norwegian drug information centers.

Background Drug-related problems have been identified as a major contributor to emergency room visits, hospitalizations, and death. The most commonly implicated medications are nonsteroidal anti-inflammatory drugs (NSAIDs), antiplatelets, and anticoagulants. Considering a significant proportion of these harms are preventable, indicators to identify risky prescribing before they lead to harm have been developed. Objective To examine the prevalence and patterns of potentially inappropriate prescriptions (PIPs) in a primary care population who are using high-risk medications. Setting This study was performed within two multi-disciplinary family medicine teaching clinics in Winnipeg, Canada. Method A cross-sectional electronic/paper chart audit was conducted within two multi-disciplinary family medicine teaching clinics to evaluate the prevalence of 13 evidence-based high-risk prescriptions. Patients were included if they were prescribed an oral NSAID, antiplatelet, or an anticoagulant within the 12 month period between June 2012 and June 2013. Main outcome measure The proportion of PIPs associated with an increased bleeding risk for NSAIDs, antiplatelets, and anticoagulants. Results Of the 567 patients included in the review, 198 (35 %) patients had received at least 1 PIP in the past year. The most common PIP was the use of an oral NSAID with one or more GI risk factors without adequate gastro-protection. Only 34 (6 %) of these patients received a full medication review performed by a pharmacist. Although not statistically significant, patients who received a medication review had fewer inappropriate prescriptions (27 % with review, 35 % without). Conclusion Over one-third of the patients who were using high-risk medications were using them potentially inappropriately. Although pharmacists have been shown to reduce the amount of inappropriate prescribing, very few patients using these medications were referred to the pharmacist for a full medication review

As a result of the lack of an adequate regulation, the supply and the use of medicines is irrational in Spain. In order to know the characteristics of the prescription and use of drugs among the elderly, two drug utilization studies were carried out. The first study was an analysis of 981 prescriptions from an outpatient clinic of the Spanish Social Security. The results show that a high proportion of fixed-dose combinations were prescribed and that drugs without any demonstrated therapeutic value are often prescribed for the elderly. The second study was a survey of 389 individuals randomly chosen among people affiliated with a pensioners' club. The results show that drug use is highly prevalent among the elderly, that many medicines without any demonstrated benefit are being taken, and that potentially harmful drugs were being used by a high proportion of patients without medical follow-up. The prevalence of the use of some particular groups of drugs is also presented.

Influences on GPs' decision to prescribe new drugs-the importance of who says what.

PubMed

Prosser, Helen; Almond, Solomon; Walley, Tom

2003-02-01

The aim of this study was to understand the range of factors that influence GPs' uptake of new drugs A total of 107 GPs selected purposively from high, medium and low new drug prescribing practices in two health authorities in the north west of England were interviewed using the critical incident technique with semi-structured interviews. Interview topics included reasons for prescribing new drugs launched between January 1998 and May 1999; reasons for prescribing the new drug rather than alternatives; and sources of information used for each prescribed drug. Important biomedical influences were the failure of current therapy and adverse effect profile. More influential than these, however, was the pharmaceutical representative. Hospital consultants and observation of hospital prescribing was cited next most frequently. Patient request for a drug, and patient convenience and acceptability were also likely to influence new drug uptake. Written information was of limited importance except for local guidelines. GPs were largely reactive and opportunistic recipients of new drug information, rarely reporting an active information search. The decision to initiate a new drug is heavily influenced by 'who says what', in particular the pharmaceutical industry, hospital consultants and patients. The decision to 'adopt' a new drug is clinched by subsequent personal clinical experience. Prescribing of new drugs is not simply related to biomedical evaluation and critical appraisal but, more importantly, to the mode of exposure to pharmacological information and social influences on decision making. Viewed within this broad context, prescribing variation becomes more understandable. Findings have implications for the implementation of evidence-based medicine, which requires a multifaceted approach.

Correctional facilities are a major provider of mental health care throughout the United States. In spite of the numerous benefits of providing care in this setting, clinicians are sometimes concerned about entering into correctional care because of uncertainty in prescribing practices. This article provides an introduction to prescription drug use, abuse, and diversion in the correctional setting, including systems issues in prescribing, commonly abused prescription medications, motivation for and detection of prescription drug abuse, and the use of laboratory monitoring. By understanding the personal and systemic factors that affect prescribing habits, the clinician can develop a more rewarding correctional practice and improve care for inmates with mental illness.

To estimate and compare the prevalence and type of potentially inappropriate prescribing (PIP) and potential prescribing omissions (PPOs) among community-dwelling older adults (≥65 years) enrolled to a clinical trial in three European countries. A secondary analysis of the Thyroid Hormone Replacement for Subclinical Hypothyroidism Trial dataset. A subset of 48/80 PIP and 22/34 PPOs indicators from the Screening Tool of Older Persons Prescriptions/Screening Tool to Alert doctors to Right Treatment (STOPP/START) V2 criteria were applied to prescribed medication data for 532/737 trial participants in Ireland, Switzerland and the Netherlands. The overall prevalence of PIP was lower in the Irish participants (8.7%) compared with the Swiss (16.7%) and Dutch (12.5%) participants (P=0.15) and was not statistically significant. The overall prevalence of PPOs was approximately one-quarter in the Swiss (25.3%) and Dutch (24%) participants and lower in the Irish (14%) participants (P=0.04) and the difference was statistically significant. The hypnotic Z-drugs were the most frequent PIP in Irish participants, (3.5%, n=4), while it was non-steroidal anti-inflammatory drug and oral anticoagulant combination, sulfonylureas with a long duration of action, and benzodiazepines (all 4.3%, n=7) in Swiss, and benzodiazepines (7.1%, n=18) in Dutch participants. The most frequent PPOs in Irish participants were vitamin D and calcium in osteoporosis (3.5%, n=4). In the Swiss and Dutch participants, they were bone antiresorptive/anabolic therapy in osteoporosis (9.9%, n=16, 8.6%, n=22) respectively. The odds of any PIP after adjusting for age, sex, multimorbidity and polypharmacy were (adjusted OR (aOR)) 3.04 (95% CI 1.33 to 6.95, P<0.01) for Swiss participants and aOR 1.74 (95% CI 0.79 to 3.85, P=0.17) for Dutch participants compared with Irish participants. The odds of any PPOs were aOR 2.48 (95% CI 1.27 to 4.85, P<0.01) for Swiss participants and aOR 2.10 (95% CI 1.11 to 3.96, P=0

Ensuring appropriate prescribing is an important challenge for the health service, and the need for research that takes account of the reasons behind individual general practitioners' (GPs) prescribing decisions has been highlighted. To explore differences among GPs in their decisions to prescribe new drugs. Qualitative approach, using in-depth semistructured interviews. Northern and Yorkshire Health Authority Region. Participants were identified from a random sample of 520 GPs in a quantitative study of patterns of uptake of eight recently introduced drugs. Purposeful sampling ensured inclusion of GPs prescribing any of the eight drugs and working in a range of practice settings. Fifty-six GPs were interviewed, using a topic guide. Interviews were recorded on audiotape. Transcribed text was methodically coded and data were analysed by constantly comparing emerging themes. Both low and high prescribers shared a view of themselves as conservative in their prescribing behaviour. Low prescribers appeared to conform more strongly to group norms and identified a consensus among practice partners in prescribing and cost-consciousness. Conformism to group norms was represented by a commitment to practice formularies. High prescribers more often expressed themselves to be indifferent to drug costs and a shared practice ethos. A shift in the attitudes of some GPs is required before cost-effectiveness is routinely incorporated in drug prescribing. The promotion of rational prescribing is likely to be more successful if efforts are focused on GPs' appreciation of cost issues and attitudes towards shared decision-making and responsibility.

nursing-home patients usually have many medical problems and often take many drugs. They are therefore at risk from drug side effects and interactions. to evaluate the impact of a visit by a general practitioner and a comprehensive repeat prescribing review on the consumption of inappropriate drugs in nursing homes. two general practitioners made one comprehensive visit to four randomly selected nursing homes. In each home we discussed all patients in detail with a senior member of staff. We reviewed the prescribing record of each patient and stopped items if we considered them inappropriately prescribed or unnecessary. repeat prescriptions were altered in 65% of patients: 51% had an item stopped and 26% had an item changed to a cheaper alternative or the dose reduced. There was a reduction in the mean number of repeat prescriptions prescribed. a single visit by a general practitioner to a nursing home and a comprehensive repeat prescribing review can lead to a reduction in the number of items prescribed and to substantial savings for the health service. Further rigorous, cost-effectiveness studies are needed.

potentially inappropriate medication (PIM) prescribing is common in older people and leads to adverse events and hospital admissions. to determine whether prevalence of PIM prescribing varies according to healthcare supply and socioeconomic status. all prescriptions dispensed at community pharmacies for patients aged 75 and older between 1 January  and 31 March 2012 were retrieved from French Health Insurance Information System of the Nord-Pas-de-Calais Region for patients affiliated to the Social Security scheme. PIM was defined according to the French list of Laroche. The geographic distribution of PIM prescribing in this area was analysed using spatial scan statistics. overall, 65.6% (n = 207,979) of people aged 75 years and over living in the Nord-Pas-de-Calais Region were included. Among them, 32.6% (n = 67,863) received at least one PIM. The spatial analysis identified 16 and 10 clusters of municipalities with a high and a low prevalence of PIM prescribing, respectively. Municipalities with a low prevalence of PIM were characterised by a high socioeconomic status whereas those with a high prevalence of PIM were mainly characterised by a low socioeconomic status, such as a high unemployment rate and low household incomes. Markers of healthcare supply were weakly associated with high or low prevalence clusters. significant geographic variation in PIM prescribing was observed in the study territory and was mainly associated with socioeconomic factors. © The Author 2017.

Background Inappropriate prescribing and misuse of asthma medication, have been identified as potentially preventable factors linked to asthma exacerbations and deaths. A recent report by the National Review of Asthma Deaths drew attention to the excessive prescribing of reliever medication, and under-prescribing of controlled medication in the United-Kingdom (UK). The inappropriate prescribing of long-acting beta agonist (LABA) bronchodilator inhalers, as either a monotherapy or without inhaled corticosteroids (ICS) has been highlighted as a major preventable factor of asthma exacerbations and deaths. To determine whether the prevalence of inappropriate LABA therapy use in asthma in the UK and in France has changed over time. Methods Two interval, parallel, population-based cohorts (2007 and 2013), were developed in each country, utilising the UK Optimum Patient Care Research Database and the French Permanent Beneficiaries Sample database. Following inclusion, patients aged 6–40 years were studied over a 12-month period. The use of LABAs without ICS, and ≥2-fold higher use of LABA compared with ICS were investigated. Analyses were stratified by age groups: children (6–13 years) and adults (14–40 years). Results Overall, 39,743 UK and 4,910 French patients were included in 2007 and 14,036 and 5,657 in 2013. In 2013, LABA use without ICS occurred in 0.1% and 1.5% of UK and French adults respectively. This was a marked reduction from 2007 UK and French figures of 0.4% and 2.6% respectively (P<0.05 for both). Excessive use of LABA relative to ICS occurred in 0.2% of UK adults and in 0.7% of French adults in 2013. These percentages represented a decrease from the 2007 figures of 0.6% and 1.4% for UK (P=0.29) and France (P=0.003), respectively. In 2007, LABA inappropriate use was more frequent in French than UK asthmatic children (P<0.0001), but showed a downward trend by time in both countries (0.1% in 2013 in both countries).

Over the recent years there has been a steady 7% yearly increase in prescribing costs, which accounts for 17% of the Slovene national health care budget. Substitution of branded products by generic equivalents can offer savings. General practitioners (GPs) are often concerned about the quality of generic products and possible legal liabilities associated with their use. We wanted to examine the attitudes of GPs in Slovenia towards generic drug prescribing. We conducted a postal survey of a random sample of 200 out of 800 GPs in Slovenia from the National Health Insurance Institute database. GPs were asked 21 questions regarding their knowledge on generic drugs, awareness of prescribing costs, prices of generic drugs relative to brand name drugs and their attitude towards use of generic drugs. The 117 (58.5%) replies we received represent 15% of the GP population in Slovenia. 66.1% of GPs considered rising costs of medicines to be a serious problem for the health care budget. Each week, over 50% of GPs experienced demands from patients for specific drugs and the majority of GPs usually met their patients' demands or requests from hospital consultants for branded products. 38.3% of GPs did not take price into consideration when prescribing drugs. The majority of GPs (88.9%) perceived generics to have the same effectiveness as branded drugs. One quarter of GPs would prescribe more generics if additional clinical trials were presented. 37.3% would follow advice of academic detailers and 30.3% expected the generics to be even cheaper than they were. Independent detailing was welcomed by 63.8% of GPs because of the big influence of the pharmaceutical industry on the prescribing habits. 15.5% thought that the industry had a tremendous impact on their prescribing patterns. Slovene GPs are aware of the cost of prescribed drugs. They are willing to accept independent academic detailing to improve their prescribing and are willing to increase generic drugs under certain

Coroners files and toxicological records of fatally-injured drivers in Victoria from 2000 to 2006 and from 2007 to 2013 were reviewed in separate studies to establish the role of prescribed drugs on crash risk. 2638 driver fatalities were included in the study, which represented over 97% of all driver fatalities in this period. The detection limits of the drugs were at the low end of those seen with common illicit drugs or prescribed drugs. Drugs of any type were found in 34.4% of the study group, medicinal drugs 21.2%, and alcohol (≥0.05 gram/100mL) was found in 24.8%. The prevalence of the most common drugs detected that are legally available by prescription were anti-depressants (7.9%), benzodiazepines (7.0%), opiates/opioids (6.6%), and sedating anti-histamines (1.1%). Each driver was assessed for responsibility using a previously published and validated method. The crash risk of drivers taking opioids, benzodiazepines, or anti-depressants (primarily the serotonin reuptake inhibitors), were not significantly over-represented compared to the drug-free control group, although there was a suggestion of increased crash risk for benzodiazepines. Crash risk was elevated for drivers using cannabis (by presence of THC in blood at>2ng/mL) and amphetamines. These data show that drivers using medicinal drugs alone are unlikely to show significant crash risk even if drugs are potentially impairing. Copyright © 2016 Elsevier Ireland Ltd.

Background Drug formularies have been created by third party payers to control prescription drug usage and manage costs. Physicians try to provide the best care for their patients. This research examines family physicians' attitudes regarding prescription reimbursement criteria, prescribing and advocacy for patients experiencing reimbursement barriers. Methods Focus groups were used to collect qualitative data on family physicians' prescribing decisions related to drug reimbursement guidelines. Forty-eight family physicians from four Ontario cities participated. Ethics approval for this study was received from the Hamilton Health Sciences/Faculty of Health Sciences Research Ethics Board at McMaster University. Four clinical scenarios were used to situate and initiate focus group discussions about prescribing decisions. Open-ended questions were used to probe physicians' experiences and attitudes and responses were audio recorded. NVivo software was used to assist in data analysis. Results Most physicians reported that drug reimbursement guidelines complicated their prescribing process and can require lengthy interpretation and advocacy for patients who require medication that is subject to reimbursement restrictions. Conclusion Physicians do not generally see their role as being cost-containment monitors and observed that cumbersome reimbursement guidelines influence medication choice beyond the clinical needs of the patient, and produce unequal access to medication. They observed that frustration, discouragement, fatigue, and lack of appreciation can often contribute to family physicians' failure to advocate more for patients. Physicians argue cumbersome reimbursement regulations contribute to lower quality care and misuse of physicians' time increasing overall health care costs by adding unnecessary visits to family physicians, specialists, and emergency rooms.

There is limited evidence regarding the quality of prescribing for children in primary care. Several prescribing criteria (indicators) have been developed to assess the appropriateness of prescribing in older and middle-aged adults but few are relevant to children. The objective of this study was to develop a set of prescribing indicators that can be applied to prescribing or dispensing data sets to determine the prevalence of potentially inappropriate prescribing in children (PIPc) in primary care settings. Two-round modified Delphi consensus method. Irish and UK general practice. A project steering group consisting of academic and clinical general practitioners (GPs) and pharmacists was formed to develop a list of indicators from literature review and clinical expertise. 15 experts consisting of GPs, pharmacists and paediatricians from the Republic of Ireland and the UK formed the Delphi panel. 47 indicators were reviewed by the project steering group and 16 were presented to the Delphi panel. In the first round of this exercise, consensus was achieved on nine of these indicators. Of the remaining seven indicators, two were removed following review of expert panel comments and discussion of the project steering group. The second round of the Delphi process focused on the remaining five indicators, which were amended based on first round feedback. Three indicators were accepted following the second round of the Delphi process and the remaining two indicators were removed. The final list consisted of 12 indicators categorised by respiratory system (n=6), gastrointestinal system (n=2), neurological system (n=2) and dermatological system (n=2). The PIPc indicators are a set of prescribing criteria developed for use in children in primary care in the absence of clinical information. The utility of these criteria will be tested in further studies using prescribing databases. Published by the BMJ Publishing Group Limited. For permission to use (where not already granted

Objective: To describe neurologists' Medicare Part D prescribing patterns and the potential effect of generic substitutions and price negotiation, which is currently prohibited. Methods: The 2013 Medicare Part D Prescriber Public Use and Summary files were used. Payments for medications were aggregated by provider and drug (brand or generic). Payment, proportion of generic claims or day's supply, and median payment per monthly supply of medication were calculated by physician specialty and drug. Savings from generic substitution were estimated for brand drugs with a generic available. Medicare prices were compared to drug prices negotiated by the federal government with pharmaceutical manufacturers for the Veterans Administration (VA). Results: Neurologists comprised 13,060 (1.2%) providers with $5.0 billion (4.8%) in total payments, third highest of all specialties, with a median monthly payment of $141 (interquartile range $85–225). Multiple sclerosis drugs had the highest payments ($1.8 billion). Within neurologic disease groups ($3.4 billion in payments), 54.2%–91.8% of monthly supplies were generic, but 11.9%–71.3% of the payment was for generic medications. Generic substitution resulted in a $269 million (6.5%) payment decrease. VA pricing resulted in $1.5 billion (44.5% of $3.4 billion) in savings. Conclusions: High payment per monthly supply of medication underlies the high total neurology drug payments and is driven by multiple sclerosis drugs. Lowering drug expenditures by Medicare should focus on drug prices. PMID:27009256

A review of the factors influencing antimicrobial prescribing.

There are multiple benefits of appropriate antimicrobial prescribing: it has a direct impact on clinical outcomes, avoids adverse effects, is cost effective and, perhaps most importantly, it helps to prevent the emergence of resistance. However, any physician can prescribe antibiotics, which is not the case with other clinically relevant drugs. There is great variability in the prescribing physician's (PP) training, motivation, workload and setting, including accessibility to infectious diseases consultants and/or diagnostic techniques, and therefore there is a high risk of inappropriate prescription. Many antibiotic prescribing errors occur around the selection and duration of treatment. This includes a low threshold for the indication of antibiotics, delayed initiation of treatment when indicated, limited knowledge of local antimicrobial resistance patterns by the PPs, errors in the final choice of dose, route or drug and a lack of de-escalation. Similarly, the prescription of prophylactic antibiotics to prevent surgical site infections, despite being commonly accepted, is suboptimal. Factors that may explain suboptimal use are related to the absence of well-defined protocols, poor knowledge of prophylactic protocols, miscommunication or disagreement between physicians, logistical problems, and a lack of audits. A proper understanding of the prescribing process can guide interventions to improve the PP's practices. Some of the potential interventions included in a stewardship program are education in antimicrobial prescribing, information on the local resistance patterns and accessibility to a qualified infectious diseases consultant.

Quality of antimicrobial drug prescription in hospital.

PubMed

van der Meer, J W; Gyssens, I C

2001-01-01

There is worldwide concern about the development of antimicrobial resistance [1]. Selective pressure by antimicrobial drugs is by far the most important driving force for the development of resistance. Antimicrobial drugs are among the most commonly prescribed drugs in hospitals. In developed countries, some 30% of the hospitalized patients will be treated with these drugs. It is generally accepted that antimicrobial prescribing is often suboptimal, even in a country like the Netherlands, where both antibiotic consumption and microbial resistance rates are low [2,3]. The major problem with inappropriate prescribing is because of insufficient education in infectious diseases and antimicrobial therapy. Often, the prescription of these drugs with little toxicity is unjustified because of insecurity about the diagnosis of the clinician; 'drugs of fear' [4]. In our surveys, some 15% of the antibiotic prescriptions in surgical and internal medicine wards were considered unjustified [5,6]. Many prescribers are not yet fully aware that their justified or unjustified prescription adds to the resistance problem. In this paper, aspects of the quality of antimicrobial prescribing in the hospital setting will be discussed.

Abstract Background Multiple studies estimate that inappropriate antibiotic prescribing ranges from 30–50% in hospitalized patients, but few have included pediatric patients. Pediatric studies characterizing inappropriate prescribing are needed to target and improve antimicrobial stewardship program (ASP) efforts. Methods Cross-sectional analysis of antimicrobial prescribing at 30 U.S. children’s hospitals. Participating hospitals were academic, tertiary care hospitals in the Sharing Antimicrobial Reports for Pediatric Stewardship (SHARPS) collaborative. Subjects were children 0–17 years with an active antibiotic order at 0800 on a single day during three consecutive calendar quarters (Q3 2016 – Q1 2017). Each hospital’s ASP used a standardized survey to collect data on antibiotic orders and evaluate appropriateness. Data were pooled from the three surveys. The primary outcome was the pooled estimate for the percentage of prescriptions classified as inappropriate. Secondary outcomes were pooled estimates for indication, reason for inappropriate use, and ASP review status for each antibiotic. Results Of 19,598 children hospitalized on survey days, 6,922 (35%) had ≥1 active antibiotic order. Median age of children receiving antibiotics was 3.7 years (0.5, 10.9). Figures 1 and 2 show the most common antibiotics and indications. Of all antibiotic orders, 1,514 (15%) were classified as inappropriate, and 19% of patients with antibiotic orders had at least one inappropriate order. The most common reasons for inappropriate use were bug-drug mismatch (26%), surgical prophylaxis > 24 hours (18%) and unnecessary duplicate therapy (12%). ASPs would not have routinely reviewed 50% of all inappropriate orders. An additional 22% of inappropriate orders were for antibiotics typically reviewed by ASPs, but were yet to be reviewed at the time of the survey. Conclusion Across 30 children’s hospitals, approximately 1 in 3 hospitalized children is receiving an antibiotic

Antimicrobial use is known to select for the emergence of resistant strains of bacteria; therefore prudent use in both human and veterinary medicine is essential to preserve their efficacy. To characterise antimicrobial prescribing patterns in UK equine practice and evaluate factors associated with prescribing. A postal questionnaire including 4 clinical scenarios was sent to 740 veterinary surgeons that treat horses. Data were collected on the clinician, their practice and sources of information regarding antimicrobials and their use. Multivariable logistic regression analysis was used to ascertain factors associated with 5 outcomes; prescribing off-licence drugs; prescribing at incorrect doses; prescribing 3rd or 4th generation cephalosporins; prescribing fluoroquinolones and prescribing potentiated sulphonamides. Questionnaires were completed by 38% of veterinary surgeons who were sent questionnaires. Less than 1% of practices had antimicrobial use guidelines. Trimethoprim-sulphonamides were most commonly prescribed in each clinical scenario. Eleven percent of prescriptions were for antimicrobial drugs not licensed for use in horses in the UK. Five percent of prescriptions for licensed antimicrobials were under the recommended dose rate and 56% over the recommended dose rate. Fluoroquinolones and 3rd and 4th generation cephalosporins accounted for 1 and 3% of prescriptions, respectively. Veterinary surgeons working at referral practices were more likely to prescribe 3rd and 4th generation cephalosporins and fluoroquinolones and off-licence antimicrobials whereas those working in first-opinion practices were more likely to prescribe potentiated sulphonamides. Sources of information regarding antimicrobials also had an effect on prescribing. Prescription of antimicrobials at inappropriate doses was common even when provided with the weight of the animal. It is uncommon for UK equine veterinary practices to have guidelines for antimicrobial use. The introduction of

Current antiepileptic drugs (AEDs) have several shortcomings. For example, they fail to control seizures in 30% of patients. Hence, there is a need to identify new AEDs. Drug repurposing is the discovery of new indications for approved drugs. This drug "recycling" offers the potential of significant savings in the time and cost of drug development. Many drugs licensed for other indications exhibit antiepileptic efficacy in animal models. Our aim was to create a database of "prescribable" drugs, approved for other conditions, with published evidence of efficacy in animal models of epilepsy, and to collate data that would assist in choosing the most promising candidates for drug repurposing. The database was created by the following: (1) computational literature-mining using novel software that identifies Medline abstracts containing the name of a prescribable drug, a rodent model of epilepsy, and a phrase indicating seizure reduction; then (2) crowdsourced manual curation of the identified abstracts. The final database includes 173 drugs and 500 abstracts. It is made freely available at www.liverpool.ac.uk/D3RE/PDE3. The database is reliable: 94% of the included drugs have corroborative evidence of efficacy in animal models (for example, evidence from multiple independent studies). The database includes many drugs that are appealing candidates for repurposing, as they are widely accepted by prescribers and patients-the database includes half of the 20 most commonly prescribed drugs in England-and they target many proteins involved in epilepsy but not targeted by current AEDs. It is important to note that the drugs are of potential relevance to human epilepsy-the database is highly enriched with drugs that target proteins of known causal human epilepsy genes (Fisher's exact test P-value < 3 × 10 -5 ). We present data to help prioritize the most promising candidates for repurposing from the database. The PDE3 database is an important new resource for drug

"Nudges" that influence decision making through subtle cognitive mechanisms have been shown to be highly effective in a wide range of applications, but there have been few experiments to improve clinical practice. To investigate the use of a behavioral "nudge" based on the principle of public commitment in encouraging the judicious use of antibiotics for acute respiratory infections (ARIs). Randomized clinical trial in 5 outpatient primary care clinics. A total of 954 adults had ARI visits during the study timeframe: 449 patients were treated by clinicians randomized to the posted commitment letter (335 in the baseline period, 114 in the intervention period); 505 patients were treated by clinicians randomized to standard practice control (384 baseline, 121 intervention). The intervention consisted of displaying poster-sized commitment letters in examination rooms for 12 weeks. These letters, featuring clinician photographs and signatures, stated their commitment to avoid inappropriate antibiotic prescribing for ARIs. Antibiotic prescribing rates for antibiotic-inappropriate ARI diagnoses in baseline and intervention periods, adjusted for patient age, sex, and insurance status. Baseline rates were 43.5% and 42.8% for control and poster, respectively. During the intervention period, inappropriate prescribing rates increased to 52.7% for controls but decreased to 33.7% in the posted commitment letter condition. Controlling for baseline prescribing rates, we found that the posted commitment letter resulted in a 19.7 absolute percentage reduction in inappropriate antibiotic prescribing rate relative to control (P = .02). There was no evidence of diagnostic coding shift, and rates of appropriate antibiotic prescriptions did not diminish over time. Displaying poster-sized commitment letters in examination rooms decreased inappropriate antibiotic prescribing for ARIs. The effect of this simple, low-cost intervention is comparable in magnitude to costlier, more

Rationalising prescribing: Evidence, marketing and practice-relevant knowledge.

Wadmann, Sarah; Bang, Lia E

2015-06-01

Initiatives in the name of 'rational pharmacotherapy' have been launched to alter what is seen as 'inappropriate' prescribing practices of physicians. Based on observations and interviews with 20 general practitioners (GPs) in 2009-2011, we explored how attempts to rationalise prescribing interact with chronic care management in Denmark. We demonstrate how attempts to rationalise prescribing by informing GPs about drug effects, adverse effects and price do not satisfy GPs' knowledge needs. We argue that, for GPs, 'rational' prescribing cannot be understood in separation from the processes that enable patients to use medication. Therefore, GPs do much more to obtain knowledge about medications than seek advice on 'rational pharmacotherapy'. For instance, GPs also seek opportunities to acquaint themselves with the material objects of medication and medical devices. We conceptualise the knowledge needs of GPs as a need for practice-relevant knowledge and argue that industry sales representatives are granted opportunity to access general practice because they understand this need of GPs.

Objective To elicit prescribers' preferences for behavioural economics interventions designed to reduce inappropriate antibiotic prescribing, and compare these to actual behaviour. Design Discrete choice experiment (DCE). Setting 47 primary care centres in Boston and Los Angeles. Participants 234 primary care providers, with an average 20 years of practice. Main outcomes and measures Results of a behavioural economic intervention trial were compared to prescribers' stated preferences for the same interventions relative to monetary and time rewards for improved prescribing outcomes. In the randomised controlled trial (RCT) component, the 3 computerised prescription order entry-triggered interventions studied included: Suggested Alternatives (SA), an alert that populated non-antibiotic treatment options if an inappropriate antibiotic was prescribed; Accountable Justifications (JA), which prompted the prescriber to enter a justification for an inappropriately prescribed antibiotic that would then be documented in the patient's chart; and Peer Comparison (PC), an email periodically sent to each prescriber comparing his/her antibiotic prescribing rate with those who had the lowest rates of inappropriate antibiotic prescribing. A DCE study component was administered to determine whether prescribers felt SA, JA, PC, pay-for-performance or additional clinic time would most effectively reduce their inappropriate antibiotic prescribing. Willingness-to-pay (WTP) was calculated for each intervention. Results In the RCT, PC and JA were found to be the most effective interventions to reduce inappropriate antibiotic prescribing, whereas SA was not significantly different from controls. In the DCE however, regardless of treatment intervention received during the RCT, prescribers overwhelmingly preferred SA, followed by PC, then JA. WTP estimates indicated that each intervention would be significantly cheaper to implement than pay-for-performance incentives of $200/month

Previous studies have reported that elderly assisted-living residents use multiple drug combinations and inappropriate drugs.The aim of this study was to assess the drug use and its consequences in residents of a nursing facility.We examined the prescriptions of all residents in a nursing facility in Osaka from their medical records.Of the total 67 residents, 48 were women.The average age of the residents was 86 years, the average number of prescription drugs they took was 6.4, and the average number of diseases present was 4.9. Correlation between the number of diseases and the drugs taken was significant (p<0.05), but the correlation between the degree of independence for activities of daily living and the number of the drugs taken was not significant.The most commonly present health condition was bone fracture.About 50% of the residents used a psychotropic drug and prescription drugs such as amantadine and hydroxyzine, which are not advisable for elderly people.It is necessary for the elderly to avoid the use of drugs that cause delirium and drowsiness, and future studies should focus on methods to prevent disuse syndrome in the elderly.

The aim of the study was to develop a European list of potentially inappropriate medications (PIM) for older people, which can be used for the analysis and comparison of prescribing patterns across European countries and for clinical practice. A preliminary PIM list was developed, based on the German PRISCUS list of potentially inappropriate medications and other PIM lists from the USA, Canada and France. Thirty experts on geriatric prescribing from Estonia, Finland, France, the Netherlands, Spain and Sweden participated; eight experts performed a structured expansion of the list, suggesting further medications; twenty-seven experts participated in a two-round Delphi survey assessing the appropriateness of drugs and suggesting dose adjustments and therapeutic alternatives. Finally, twelve experts completed a brief final survey to decide upon issues requiring further consensus. Experts reached a consensus that 282 chemical substances or drug classes from 34 therapeutic groups are PIM for older people; some PIM are restricted to a certain dose or duration of use. The PIM list contains suggestions for dose adjustments and therapeutic alternatives. The European Union (EU)(7)-PIM list is a screening tool, developed with participation of experts from seven European countries, that allows identification and comparison of PIM prescribing patterns for older people across European countries. It can also be used as a guide in clinical practice, although it does not substitute the decision-making process of individualised prescribing for older people. Further research is needed to investigate the feasibility and applicability and, finally, the clinical benefits of the newly developed list.

To characterize prescribing of proton pump inhibitors (PPIs) and medicines that increase gastrointestinal bleeding risk (ulcerogenic) in older people from 1997 to 2012 and assess factors associated with maximal-dose prescribing in long-term PPI users. Repeated cross-sectional study of pharmacy claims data. Eastern Health Board region of Ireland. Individuals aged 65 and older from a means-tested health plan in 1997, 2002, 2007, and 2012 (range 78,489-133,884 individuals). PPI prescribing prevalence was determined per study year, categorized according to duration (≤8 or >8 weeks), dosage (maximal or maintenance), and co-prescribed drugs. Logistic regression in long-term PPI users was used to determine whether age, sex, polypharmacy, and ulcerogenic medicine use were associated with being prescribed a maximal dose rather than a maintenance dose. Adjusted odds ratios (ORs) with 95% confidence intervals (CIs) are presented. Half of this older population received a PPI in 2007 and 2012. Long-term use (>8 weeks) of maximal doses rose from 0.8% of individuals in 1997 to 23.6% in 2012. Although some ulcerogenic medicines and polypharmacy were significantly associated with maximal PPI doses, any nonsteroidal anti-inflammatory drug use was significantly associated with lower odds of maximal PPI dose (adjusted OR = 0.87, 95% CI = 0.85-0.89), as were aspirin use and older age. Adjusting for medication and demographic factors, odds of being prescribed a maximal PPI dose were significantly higher in 2012 than in 1997 (adjusted OR = 6.30, 95% CI = 5.76-6.88). Long-term maximal-dose PPI prescribing is highly prevalent in older adults and is not consistently associated with gastrointestinal bleeding risk factors. Interventions involving prescribers and patients may promote appropriate PPI use, reducing costs and adverse effects of PPI overprescribing. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Drug formularies--good or evil? A view using prescribing analyses and cost trends data.

Chapman, S

1994-01-01

In the UK, the drugs bill has almost trebled in the last 10 years and is consuming an increasing proportion of the total National Health Service spend. If the drugs bill can be limited, greater funds will be available for other areas of the health service. Therefore, cost containment measures which include prescribing from a formulary or generic prescribing are now widely encouraged. Prescribing analyses and cost trends data generated from pharmacists sending dispensed general practitioners' prescriptions to a central point for reimbursement are a valuable tool in the assessment of prescribing habits and can be used by general practitioners when preparing a formulary. In the West Midlands, such data have been used to identify areas of growth in cardiovascular drugs and problem areas where prescribing an expensive formulation has led to a dramatic increase in costs.

In 2009, Florida initiated a statewide prescription drug-monitoring program (PDMP) to encourage safer prescribing of controlled substances and reduce drug abuse and diversion. Data supporting the utility of such programs in the emergency department (ED) is scarce. This study sought to determine the effect of PDMP data on controlled substance prescribing from the ED. In this pre-post study utilizing a historical control, pharmacists in the ED provided prescribers with a summary of the PDMP data for their patients. The number of controlled substances prescribed in the intervention group was compared with that prescribed in the historical control to determine if the intervention resulted in a change in the average number of controlled substance prescribed. Among the 710 patients evaluated, providing prescribers with PDMP data did not alter the average number of controlled substance per patient prescribed (0.23 controlled substances per patient in the historical control compared with 0.28 controlled substances per patient in the intervention group; 95% confidence interval [CI], -0.016 to 0.116; P = .125). All prescribers surveyed indicated that having PDMP data altered their controlled substance prescribing and felt more comfortable prescribing controlled substances. Although the results did not demonstrate a change in the average number of controlled substances prescribed when prescribers were provided with PDMP data, results from the survey indicate that prescribers felt the data altered their prescribing of controlled substances, and thus were more contented prescribing controlled substances.

A drug formulary comprising 249 preparations of 132 drugs and drug combinations was prepared by the partners in a three-doctor general practice serving more than 5000 patients. No attempt was made to change to generic prescribing nor were repeat prescription drugs altered. Introduction of the formulary in September 1981 was followed by an increase in the proportion of prescriptions containing drugs from the formulary from about 55% to more than 60% for both repeat and non-repeat prescriptions. The proportion of formulary drugs on non-repeat prescriptions reached a maximum of 78% within the first year with the additional influence of information feedback. Over the first year the level of formulary drugs used for both repeat and nonrepeat prescribing levelled off at about 62%. Even with these modest changes, when compared with the costs of general practice prescribing in Scotland as a whole, the introduction of the formulary resulted in savings of approximately 10% within the practice for the mean ingredient costs both per patient and per prescription.

Several drugs that are known to exhibit teratogenic or fetotoxic risks when used during pregnancy should not be prescribed to pregnant women. However, most women of childbearing age use medications, and drug use cannot always be avoided during pregnancy, especially for women with chronic diseases for whom the benefit of treatment outweighs the potential risk of the drug for the fetus. Nevertheless, it is often possible to replace a drug with another one that has been better evaluated. The aim of the present study was to describe the prescribing of drugs to pregnant women before and during pregnancy in order to examine whether the occurrence of pregnancy modifies drug prescribing and dispensing to women. In particular, drugs that are contraindicated or must be avoided during pregnancy, such as retinoids, ACE inhibitors, angiotensin II receptor blockers, NSAIDs and valproic acid, will be analysed. This retrolective study used data already prospectively recorded in the database of the French Health Insurance Service. It analysed pharmacy records of women who gave birth between 1 January 2007 and 31 December 2007 in Midi-Pyrenees. Pharmacy data were analysed from 9 months before pregnancy until delivery. Drugs were classified according to the Anatomical Therapeutic Chemical code. The study included 23 898 women. Approximately 77% and 96% of the women received at least one prescription before and during pregnancy, respectively. The number of women who were prescribed contraindicated drugs significantly decreased with pregnancy (p < 0.0001). Most of the drugs were stopped during the 3 months before pregnancy without alternative treatment, even for chronic diseases. However, for some women, potentially dangerous prescriptions were maintained during pregnancy, and for others these drugs were dispensed for the first time during critical periods of pregnancy. Despite recommendations, some teratogenic and/or fetotoxic drugs are still prescribed and dispensed to pregnant

Prescribing medicines in an unlicensed and off-label manner for children is a widespread practice around the world. To determine the extent and predictors of off-label respiratory drug prescriptions for children in the outpatient clinics of a hospital in Malaysia. Outpatient clinics at the Universiti Kebangsaan Malaysia Medical Centre, a tertiary teaching hospital in Malaysia. The pharmacy-based computer system and medical records of the patients were utilized to collect data from 220 pediatric patients who were prescribed at least one respiratory drug from July 2011 to December 2011. Characteristics of the off-label respiratory drug prescriptions were measured. A total of 134 children (60.9 %) received at least one respiratory drug prescribed in an off-label manner. The most common reasons for the off-label prescribing of drugs were off-label use by indication (31.5 %), followed by higher than the recommended dose (24.9 %) and lower than the recommended frequency (17.1 %). Diphenhydramine was the most common respiratory drug prescribed off-label. The number of medications prescribed was the only significant predictor of off-label prescription of respiratory drugs. Pediatric patients receiving 4-6 medications were 7.8 times more likely to receive at least one off-label respiratory drug compared to pediatric patients that received 1-3 medications (OR 7.8, 95 % CI 1.74-37.44). There was substantial prescribing of respiratory drugs for children in an off-label manner at the outpatient clinics at the Universiti Kebangsaan Malaysia Medical Centre. This highlights the need for more research to be carried out on respiratory drugs in the pediatric population.

Aims To investigate the extent of acute coprescribing in primary care to children on chronic antiepileptic therapy, which could give rise to potentially harmful drug–drug interactions. Design Acute coprescribing to children on chronic antiepileptic drug therapy in primary care was assessed in 178 324 children aged 0–17 years for the year 1 November 1999 to 31 October 2000. Computerized prescribing data were retrieved from 161 representative general practices in Scotland. Setting One hundred and sixty-one general practices throughout Scotland. Results During the study year 723 (0.41%) children chronically prescribed antiepileptic therapy were identified. Fourteen antiepileptic agents were prescribed, with carbamazepine, sodium valproate and lamotrigine accounting for 80% of the total. During the year children on chronic antiepileptic therapy were prescribed 4895 acute coprescriptions for 269 different medicines. The average number of acute coprescriptions for non-epileptic drug therapy were eight, 11, six, and six for the 0–1, 2–4, 5–11, and 12–17-year-olds, respectively. Of these acute coprescriptions 72 (1.5%) prescribed to 22 (3.0%) children were identified as a potential source of clinically serious interactions. The age-adjusted prevalence rates for potentially serious coprescribing were 86, 26, 22, and 33/1000 children chronically prescribed antiepileptic therapy in the 0–1, 2–4, 5–11, and 12–17-year-old age groups, respectively. The drugs most commonly coprescribed which could give rise to such interactions were antacids, erythromycin, ciprofloxacin, theophylline and the low-dose oral contraceptive. For 10 (45.5%0 of the 20 children identified at risk of a potentially clinically serious adverse drug interaction, the acute coprescription was prescribed off label because of age or specific contraindication/warning. Conclusions In primary care, 3.0% of children on chronic antiepileptic therapy are coprescribed therapeutic agents, which could

To ascertain the disease pattern and drug prescribing pattern of the patients attending Kathmandu Medical College Health Center, Duwakot. It is a cross sectional study conducted at Kathmandu Medical College (KMC) health Center, Duwakot during the month of Ashad to Mangshir, 2060. The sample size included was 292 patients attending the Health Center during this period. Prescription details were used as study tools to acquire information regarding patient's name, age, complaints for which consultation was sought, investigations, diagnosis, name of the drug which is prescribed and instruction for diet. Age of patients in this study ranged from 0-80 years. A total of 165 (56.50%) were male and 127 (43.49%) were female. Out of 165 male of different age group ranging from 0-80 years, most of the patient i.e. 25(15.15%) were suffering from viral fever followed by cut/injury, allergy, diarrhoea, abdomen pain, fungal infection, HTN (hypertension), cold/cough/sore throat, sinusitis, muscular skeletal pain, joint pain, contact dermatitis, acute peptic disease (APD), headache, worm infestation, tonsillitis, pharyngitis, dizziness, eye infection, chest infection, calf and backache, viral rashes, hypo pigmentation, tension/depression, Urinary tract infection (UTI), coliolilethis, diabetes, p/r bleeding and insect bite poisoning.

Generic prescribing is a sound approach to contain health care costs. However, little is known about physicians’ prescribing patterns in the Thai context. Objective: To explore physicians’ generic prescription patterns in district hospitals. Methods: Data was collected from three of the eight district hospitals between January and December 2008 (final response rate 37.5%). All participating hospitals were between 30 and 60-bed capacity. The researchers reviewed 10% of total outpatient prescriptions in each hospital. Results: A total of 14,500 prescriptions were evaluated. The majority of patients were under universal health coverage (4,367; 30.1%), followed by senior citizens’ health insurance (2,734; 18.9%), and civil servant medical benefit schemes (2,419; 16.7%). Ten thousand six hundred and seventy-one prescriptions (73.6% of total prescriptions) had at least one medication. Among these, each prescription contained 2.85 (SD=1.69) items. The majority of prescriptions (7,886; 73.9%) were prescribed by generic name only. Drugs prescribed by brand names varied in their pharmacological actions. They represented both innovator and branded-generic items. Interestingly, a large number of them were fixed-dose combination drugs. All brand name prescriptions were off patented. In addition, none of the brand-name drugs prescribed were categorized as narrow therapeutic range or any other drug that had been reported to have had problems with generic substitution. Conclusion: The majority of prescriptions in this sample were written by generic names. There is room for improvement in brand name prescribing patterns. PMID:25126136

Importance Inappropriate antimicrobial prescribing leads to antimicrobial resistance and suboptimal clinical outcomes. Changing antimicrobial prescribing is a complex behavioral process that is not often taken into account in antimicrobial stewardship programs. Objective To examine whether an antimicrobial stewardship approach grounded in behavioral theory and focusing on preserving prescriber autonomy and participation is effective in improving appropriateness of antimicrobial prescribing in hospitals. Design, Setting, and Participants The Dutch Unique Method for Antimicrobial Stewardship (DUMAS) study was a prospective, stepped-wedge, participatory intervention study performed from October 1, 2011, through December 31, 2015. Outcomes were measured during a baseline period of 16 months and an intervention period of 12 months. The study was performed at 7 clinical departments (2 medical, 3 surgical, and 2 pediatric) in a tertiary care medical center and a general teaching hospital in the Netherlands. Physicians prescribing systemic antimicrobial drugs for any indication for patients admitted to the participating departments during the study period were included in the study. Interventions We offered prescribers a free choice of how to improve their antimicrobial prescribing. Prescribers were stimulated to choose interventions with higher potential for success based on a root cause analysis of inappropriate prescribing. Main Outcomes and Measures Appropriateness of antimicrobial prescriptions was determined using a validated approach based on guideline adherence and motivated guideline deviation and measured with repeated point prevalence surveys (6 per year). Appropriateness judgment was masked for the study period. Antimicrobial consumption was extracted from pharmacy records and measured as days of therapy per admission. We used linear and logistic mixed-model regression analysis to model outcomes over time. Results A total of 1121 patient cases with 700

UK guidelines for type II diabetes leave the choice of glucose lowering therapies after metformin largely to prescribers. They vary greatly in cost, and comparative effectiveness data is lacking. We set out to measure the variation in prescribing of these second-line non-insulin diabetes drugs. We evaluated time trends 1998-2016, using England's publicly available prescribing datasets, and stratified by the order prescribed to patients using the Clinical Practice Research Datalink (CPRD). We calculated the proportion of each class of diabetes drug as a percentage of the total per year. We evaluated geographical variation in prescribing using general practice-level data for the latest 12-months (to August 2017), with aggregation to Clinical Commissioning Groups (CCGs). We calculated percentiles, ranges and plotted maps. Prescribing of therapy after metformin is changing rapidly. DPP4-inhibitor use has increased markedly, now the most common second-line drug (43% prescriptions in 2016). Use of SGLT-2 inhibitors also increased rapidly (14% new second-line, 27% new third-line prescriptions in 2016). There is wide geographical variation in choice of therapies and average spend per patient. In contrast, metformin is consistently used first-line in accordance with guidelines. In England there is extensive geographical variation in the prescribing of diabetes drugs after metformin, and increasing use of higher-cost DPP4-inhibitors and SGLT-2 inhibitors over low-cost sulfonylureas. Our findings strongly support the case for comparative effectiveness trials of current diabetes drugs. This article is protected by copyright. All rights reserved.

Background Long-acting risperidone for injection is a second-generation antipsychotic indicated for the treatment of schizophrenia and related psychotic disorders. It is a relatively new agent with pharmacokinetic and dosing properties unlike those of conventional long-acting antipsychotic drugs administered by injection. Objective To determine the proportion of patients for whom long-acting risperidone for injection was prescribed appropriately in acute care settings in the Fraser Health Authority of British Columbia, according to the following 4 criteria: approved indication for therapy, 2-week dosing intervals, dose increases no sooner than every 4 weeks, and initial overlap supplementation with another antipsychotic for at least 3 weeks. A variety of other variables, including documented approval under special authority from the provincial drug coverage program, length of hospital stay, initial dose of risperidone, and total number of doses, were assessed as secondary outcomes. Methods A chart review was conducted for all patients for whom therapy with long-acting risperidone for injection was prescribed during stays in 8 acute care hospitals between July 1, 2007, and July 22, 2008. The appropriateness of prescribing was assessed according to the 4 prespecified criteria. Results Long-acting risperidone for injection was prescribed for 116 patients during the study period, and 82 of these started therapy and were included in the evaluation. The primary outcome could not be assessed for 27 of these 82 patients, because they were discharged early, and data for some or all of the 4 criteria were not available. For 33 (60%) of the 55 remaining patients, long-acting risperidone for injection had been prescribed appropriately. In contrast, for 22 (40%) of the patients, prescription of risperidone was deemed inappropriate because of failure to meet at least 1 of the 4 criteria. Premature escalation of the dose and inadequate overlap with antipsychotic supplementation

Economic and policy analysis of university-based drug "detailing".

The cost-effectiveness of quality assurance programs is often poorly documented, especially for innovative approaches. The authors analyzed the economic effects of an experimental educational outreach program designed to reduce inappropriate drug prescribing, based on a four-state randomized controlled trial (N = 435 physicians). Primary care physicians randomized into the face-to-face group were offered two individualized educational sessions with clinical pharmacists, lasting an average of 18 minutes each, concerning optimal use of three drug groups that are often used inappropriately. After the program, expenditures for target drugs prescribed by these physicians to Medicaid patients decreased by 13%, compared with controls (P = 0.002); this effect was stable over three quarters. Implementation of this program for 10,000 physicians would lead to projected drug savings (to Medicaid only) of $2,050,000, compared with resource costs of $940,000. Net savings remain high, even after adjustment for use of substitution medications. Although there was a ninefold difference in average preintervention prescribing levels between the highest and lowest thirds of the sample, all groups reduced target drug expenditures at the same rate. Targeting of higher-volume prescribers would thus further raise the observed benefit-to-cost ratio from approximately 1.8 to at least 3.0. Net benefits would also increase further if non-Medicaid savings were added, or if the analysis included quality-of-care considerations. Although print materials alone may be marginally cost-effective, print plus face-to-face approaches offer greater net benefits. The authors conclude that a program of brief, face-to-face "detailing" visits conducted by academic rather than commercial sources can be a highly cost-effective method for improving drug therapy decisions. Such an approach makes possible the enhancement of physicians' clinical expertise without relying on restriction of drug choices.

The Government of Tajikistan is reforming its health system to make access more equitable. Nonetheless, out-of-pocket expenditures (OPE) remain a key modality for purchasing health care. Drugs remain a major driver of household expenditures for health. We conducted a household survey to investigate drug prescribing patterns at primary health care (PHC) level as well as the related OPE. Adult patients in eight districts who had visited a PHC facility in the period March to May 2014 were interviewed at home, using a structured questionnaire. A descriptive analysis was conducted and regression models were constructed to identify factors influencing the number of drugs provided and the types of drugs prescribed. There were 1281 (80.1 %) patients who received a drug prescription after visiting a doctor at PHC level. 16.2 % of them had five or more drugs prescribed concomitantly. The number of drugs prescribed to patients ranged from 0 to 8 and was statistically different across regions (RRS region =3.3; Khatlon region = 3.1; p = 0.05), after adjusting for age and sex. In 31.1 % of cases, prescriptions included an intra-venous (IV) injection; in 45.6 % of cases, a non-IV injection; in 52.9 % of cases, an antibiotic; and in 61.0 % of cases, vitamins. Patients suffering from a respiratory disease had higher odds of being prescribed an IV injection and antibiotics. Vitamins were widely prescribed across all diseases. In 94.5 % of cases, the patients interviewed procured at least one of the prescribed drugs. Among those who received a prescription, 2.0 % were not able to procure at least one drug due to a lack of money. In 94.9 % of cases, respondents reported purchasing drugs in private pharmacies. Median expenditures for drugs procured following consultation were 45 TS (US$ 6.9) corresponding to 77.6 % of total expenditures related to the visit (58 TS, US$ 8.8). In a context where OPE are important, drugs represent an important income source for health

In order to move towards rational drug use in any national or local setting the methods of inquiry have to be expanded. Both the public and private sector have to be addressed. In the latter the pharmacists might be studied using a tracer, fictitious client. One important factor influencing prescribing, drug information, has rarely been assessed scientifically. Experimental studies using group randomization are, however feasible even in developing countries. The individual human being must be in the focus of drug studies and health care and health in the foreground. The combination of qualitative and quantitative methods will assist us to achieve rational drug use that is culturally acceptable, economically feasible and pharmacologically sound.

The usage of veterinary antibacterial drugs in dogs and cats in Sweden and Norway for the period 1990–1998 was investigated by use of drug wholesalers' statistics. Additionally, usage of human antibacterial drugs in these species in Sweden was investigated by use of prescription data for the period 1996–1998. On average, more than 50% of the prescribed veterinary antibacterials in Sweden were beta-lactam antibiotics. In Norway, about 75% of the preparations prescribed for dogs and cats contained sulfonamides and trimethoprim. Furthermore, the prescription data from Sweden showed a reduced usage of human antibacterials prescribed for dogs and cats since the beginning of the 1980s. Approximately 20% of the prescribed packages for dogs in the years 1996–1998 were human approved drugs. The corresponding figure for cats was 13%. The differences between the countries in the choice of antibacterial drugs can be explained by differences in the availability of approved preparations during the study period. The consumption of veterinary antibacterials in dogs and cats in Sweden during the period was in the range of 3% to 8% of the total use of veterinary antibacterials. The corresponding figures in Norway were in the range of 3% to 7%. It is of vital importance to study usage patterns of antibacterial drugs in dogs and cats in surveillance and control of bacterial resistance, but also in discussions of therapeutic appropriateness. Therefore, further research is needed in this area. PMID:11455899

The aim of the study was to describe the prescribing of drugs to pregnant women during the third trimester of pregnancy. The retrospective analysis is interested by pregnant women from August 2009 to April 2011, living in Franche-Comté. The used data are recorded in the database of the French Health Insurance Service. Drugs prescribing were analyzed and classified according to three categories: drugs that are contraindicated, not recommended drugs and drugs that are used. This classification is based on two databases: the Summaries of Product Characteristics of Vidal 2010 and data from the National Security Agency of Medicines. The potential exposure of patients was pointed out. On 15,027 patients, 80% had a prescription. Six percent of prescriptions containing drugs not recommended and 1% drugs that contraindicated. Therapeutic classes identified are analgesics, anti-infective drugs and medicines supplementing with vitamins and minerals. Contraindicated drugs (10%) are NSAIDs, rubella vaccine, cyclins and ACE inhibitors and ARBs. Approximately 2.7% of women were potentially exposed to these drugs. Despite the recommendations of the ANSM, some drugs that are contraindicated are prescribed for pregnant women in their third trimester of pregnancy. In the absence of studies, the decision must be made on a case by case basis by assessing the risk-benefit ratio. Particular care is to bring about the drugs taken in self-medication. Information and advice are key steps to avoid incidents. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

The purpose of this study is to establish the prevalence of potentially inappropriate prescribing (PIP) in middle-aged adults (45-64 years) in two populations with differing socio-economic profiles, and to investigate factors associated with PIP, using the PROMPT (PRescribing Optimally in Middle-aged People's Treatments) criteria. A retrospective cross-sectional study was conducted using 2012 data from the Enhanced Prescribing Database (EPD), covering the full population in Northern Ireland and the Health Services Executive Primary Care Reimbursement Service (HSE-PCRS) database, covering the most socio-economically deprived third of the population in this age group in the Republic of Ireland. The prevalence for each PROMPT criterion and overall prevalence of PIP were calculated. Logistic regression was used to investigate the association between PIP and gender, age group and polypharmacy. This study included 441,925 patients from the EPD and 309,748 patients from the HSE-PCRS database. Polypharmacy was common in both datasets (46.7 % in the HSE-PCRS and 20.3 % in the EPD). The prevalence of PIP was 42.9 % (95%CI 42.7, 43.1) in the HSE-PCRS and 21.1 % (95%CI 21.0, 21.2) in the EPD. Age group, female gender and polypharmacy were significantly associated with PIP in both populations (p < 0.05) and polypharmacy had the strongest association. PIP is common amongst middle-aged people with the risk of PIP increasing with polypharmacy. Differences in the prevalence of polypharmacy and PIP between the two populations may relate to heterogeneity in healthcare services and different socio-economic profiles, with higher rates of multimorbidity and associated polypharmacy in more deprived groups.

The rising costs of health care and, in particular, prescription drugs remains a challenge. Health professionals' ability to promote cost-effective prescription drug use is critical, yet this subject is not included consistently in the curriculum of most health professional schools. As experts in prescription drug selection, use, and cost, pharmacists are in a unique position to help manage prescription drug regimens for the best therapeutic outcome, while also helping to keep patients' out-of-pocket (OOP) prescription drug costs low. In addition to promoting interprofessional collaboration, pharmacy student-led lectures may provide an effective means to teach prescription drug cost-savings strategies to other health professional students and current prescribers. To describe and evaluate the impact of a 60- to 90-minute standardized, case-based lecture on prescribers' attitudes and knowledge about drug cost-containment strategies. Four trained pharmacy students delivered a lecture that focused on strategies to help underserved patients with their OOP prescription drug costs. This lecture was given to health professional students and prescribers across disciplines. For purposes of this study, underserved patients included those with no drug insurance, those with limited financial resources who were unable to pay for their prescription drugs, and those whose drug insurance had significant gaps in coverage (e.g., Medicare Part D patients). Lectures targeted future and current prescribers and were delivered in multiple settings (e.g., residents' seminars, medical grand rounds, required health policy courses for medical and nursing students). Pretest/posttest surveys were administered to assess the impact of the lecture on learners' (a) knowledge of strategies to improve underserved patients' access to needed prescription drugs; (b) willingness to address and discuss cost issues with patients; (c) likelihood of collaborating with other health care professionals; and (d

There are limited published data on the types and appropriateness of oral and intravenous (IV) antibiotics prescribed to patients receiving haemodialysis. This information is critical to optimise antibiotic prescribing. Therefore this study aims to describe the patterns of use and the appropriateness of oral and IV antibiotics prescribed to patients receiving haemodialysis. This was a prospective, observational study across four community and two hospital inpatient haemodialysis units in Melbourne, Australia. Data were collected from July 2014 to January 2015 from participants. Antibiotic regimens prescribed were compared with nationally available antibiotic guidelines and then classified as being either appropriate, inappropriate or not assessable by an expert multidisciplinary team using the National Antimicrobial Prescribing Survey tool. Overall, 114 participants consented to this study where 55.3% (63/114) received antibiotics and 235 antibiotic regimens were prescribed at a rate of 69.1 antibiotic regimens/100 patient-months. The most common oral antibiotics prescribed were amoxycillin/clavulanic acid and cephalexin. The most common IV antibiotics prescribed were vancomycin, piperacillin/tazobactam, cephazolin and ceftriaxone. The percentage of inappropriate antibiotic regimens prescribed were 34.9% (15/43) in the community setting and 22.1% (40/181) in the hospital setting. Furthermore, 29.4% (30/102) of oral and 20.5% (25/122) of IV antibiotic regimens were inappropriate with incorrect dosing as the primary reason. Although this study is limited by the sample size, it describes the high antibiotic exposure that patients receiving haemodialysis experience. Of concern is inappropriate dose and frequency being a major issue. This requires interventions focused on the quality use of medicines and antimicrobial stewardship aspects of prescribing in this population.

Medication policy development in Thailand is continually promoting rational drug use. Letrozole, an endocrine therapy drug, is usually prescribed for post-menopausal status early and advanced stage breast cancer. After Ministry of Public Health announced Letrozole as compulsory licensed drug in 2009, more breast cancer patients can access to this drug at low cost especially those within universal coverage schemes. To ensure that Letrozole is rationally prescribed, the drug utilization study was conducted. The aim of this study was to describe the appropriate use of Letrozole in breast cancer and the relationship between appropriate use and health benefit schemes. A retrospective study to evaluate use of Letrozole in breast cancer patients was performed for six months between January - June 2010 in seven regional cancer hospitals, Thailand. All prescriptions of Letrozole were identified from pharmacy dispensing databases and prescription papers. A medical record review was also performed to evaluate appropriate use referring to the drug use evaluation criteria. The approved criterion of this study was referred from the guideline of Thai National Formulary version 2010. There were 681 prescriptions of Letrozole for 254 breast cancer patients with an average age of 58.6 ± 10.0 years. The patients in universal coverage scheme (UCS), civil servant medication benefit scheme (CSMBS) and social security scheme (SSS) were 77.7%, 18.5% and 8.7% respectively. 10.6% were prescribed Letrozole for the first time. Letrozole were prescribed by oncologists (82.8%). The average number of tablets per prescription was 58 ± 10. Calcium supplements were prescribed concomitant with Letrozole for 19.4%. To assess drug use evaluation criteria, 45 prescriptions were excluded because of uncompleted clinical data, 636 prescriptions were evaluated. The study showed 86 prescriptions (13.5%) with inappropriate use including 6 (0.9%) not prescribed for estrogen receptor (ER) and/or progesterone

Most health expenditure of developing countries is on drugs and medical sundries but inappropriate use of such resources is common. To our knowledge, only few studies have been done in Africa on this issue , with inadequate consideration of the sociological context of the knowledge, attitude and practice of the prescribers especially doctors. This study presents the pooled data of the pattern of prescription drug use from three Nigerian Army hospitals using some WHO criteria, and the knowledge and attitude underlying doctors' prescribing practices in these hospitals. Retrospective cross-sectional survey of one year (March 2006-February 2007). Systematic random sample of general out patient case notes from three hospitals were collected using WHO criteria. The knowledge, attitude and practice survey of doctors at each study site towards the concept of rational drug use (RDU) were assessed using a self-administered questionnaire. Data collected from 660 case notes showed that average number of drugs per encounter was 2.8 while 49.3% of drugs were prescribed in the generic form. An average of 28.1% of patients encountered antibiotics. From the knowledge, attitude and practice survey, it is evident that 90.5% of 74 prescribers were aware of the existence of national essential drugs list but 58.1% of them did not use it as basis of prescriptions. In describing types of medicines preferred, 56.7% of prescribers claimed they prescribed a mixture of generic and branded drugs. Only 12.1% of prescribers could accurately detail the 5 steps of rational prescribing. The pattern of prescription drug use in Nigerian Army hospitals is unsatisfactory. It is characterised by high number of drugs per prescription, high rate of antibiotic usage and unscientific prescription by doctors. There is a need for further education and research on rational drug use among prescribers in Nigerian military health facilities.

INTRODUCTION As the population ages, the prevalence of hypertension also increases. Although primary care is usually the patient’s first point of contact for healthcare, little is known about the management of hypertension among elderly patients at the primary care level. This study aimed to determine the antihypertensive prescription trend for elderly patients, the predictors of antihypertensive use and any inappropriate prescribing practices in both public and private primary care settings. METHODS Data on patient demographics, diagnosis, prescription pattern, payment mode and follow-up was extracted from a cross-sectional study involving 122 public primary care clinics and 652 private primary care clinics in Malaysia. Encounters with hypertensive patients aged ≥ 60 years were included. RESULTS A total of 1,017 antihypertensive medications were prescribed – calcium channel blockers (27.1%), beta blockers (25.5%), diuretics (23.3%), angiotensin-converting enzyme inhibitors (14.9%) and angiotensin receptor blockers (6.3%). Out of the 614 patient encounters, 53.1% of the patients were prescribed monotherapy, 31.6% were prescribed dual therapy, 12.2% triple therapy, 2.8% quadruple therapy and 0.3% quintuple therapy. Type of primary care clinic and payment mode were significant predictors for the prescription of combination therapy and fixed-dose combination therapy, respectively. Four types of inappropriate prescriptions were identified. CONCLUSION Calcium channel blockers were the most common antihypertensive drug prescribed and more than half of the elderly patients were on monotherapy. Antihypertensive drug prescription was found to be associated with the type of primary care clinic and the payment mode, suggesting that prescription is influenced by the cost of the drug.

Stroke is a leading cause of death and disability; worldwide it is estimated that 16.9 million people have a first stroke each year. Lipid-lowering, anticoagulant, and antihypertensive drugs can prevent strokes, but may be underused. We analysed anonymised electronic primary care records from a United Kingdom (UK) primary care database that covers approximately 6% of the UK population. Patients with first-ever stroke/transient ischaemic attack (TIA), ≥18 y, with diagnosis between 1 January 2009 and 31 December 2013, were included. Drugs were considered under-prescribed when lipid-lowering, anticoagulant, or antihypertensive drugs were clinically indicated but were not prescribed prior to the time of stroke or TIA. The proportions of strokes or TIAs with prevention drugs under-prescribed, when clinically indicated, were calculated. In all, 29,043 stroke/TIA patients met the inclusion criteria; 17,680 had ≥1 prevention drug clinically indicated: 16,028 had lipid-lowering drugs indicated, 3,194 anticoagulant drugs, and 7,008 antihypertensive drugs. At least one prevention drug was not prescribed when clinically indicated in 54% (9,579/17,680) of stroke/TIA patients: 49% (7,836/16,028) were not prescribed lipid-lowering drugs, 52% (1,647/3,194) were not prescribed anticoagulant drugs, and 25% (1,740/7,008) were not prescribed antihypertensive drugs. The limitations of our study are that our definition of under-prescribing of drugs for stroke/TIA prevention did not address patients' adherence to medication or medication targets, such as blood pressure levels. In our study, over half of people eligible for lipid-lowering, anticoagulant, or antihypertensive drugs were not prescribed them prior to first stroke/TIA. We estimate that approximately 12,000 first strokes could potentially be prevented annually in the UK through optimal prescribing of these drugs. Improving prescription of lipid-lowering, anticoagulant, and antihypertensive drugs is important to reduce the

Objectives To evaluate the quantitative effects of the drug price reduction on pharmaceutical expenditures and the new guidelines to restrict prescribing on drug utilisation for antihypertensive drugs. Design We used an interrupted time series design with the National patient sample data of Health Insurance Review and Assessment Service in South Korea. Methods 54 295 participants who were with primary hypertension from the National patient sample data of Health Insurance Review and Assessment Service were included. The study period was from March 2011 to December 2013. The dependent variables were antihypertensive drug costs, antihypertensive drug cost per prescribing day, daily drug utilisation, average number of drugs per month, percentage of original drugs per prescription, drug overutilisation and prohibited combinations. Segmented regression analysis was used. Results The drug price reduction reduced expenditure (US$−1.51, −10.2%), and the new guidelines reduced expenditures even more (US$−2.13; −16.2%). These policies saved US$4.22 (28%) of antihypertensive drug costs per patient in December 2013 compared to March 2012. Drug price reduction policy was introduced in April 2012. We established the policy effect by comparing it before (March 2012) with after(21 months later-December 2012). The effects of the guidelines decreased expenditures, daily drug utilisation and the average number of drugs per month more than did the drug price reduction. Conclusions Both policies saved money. The guidelines were more effective over time and had fewer side effects such as increasing daily drug utilisation and number of drugs than the effects of drug price reduction. PMID:26179644

Proton pump inhibitors (PPI) are among the most commonly prescribed medicines and their overuse is widespread in both primary and secondary care. Inappropriate prescription is of particular concern among elderly patients, who have often multiple comorbidities and need many drugs. We evaluate the appropriateness of drugs for peptic ulcer or gastro-esophageal reflux disease (GERD) in a sample of elderly patients (65 years old or older) at admission and discharge in 38 internal medicine wards between January 2008 and December 2008, according to the presence of specific conditions or gastro-toxic drug combinations. Among 1155 patients eligible for the analysis, 466 (40.3%) were treated with drugs for GERD or peptic ulcer were at hospital admission and 647 (56.0%) at discharge; 62.4% of patients receiving a drug for peptic ulcer or GERD at admission and 63.2% at discharge were inappropriately treated. Among these, the number of other drugs prescribed was associated with greater use of drugs for peptic ulcer or GERD, even after adjustment for age, sex and number of diagnoses at admission (OR 95% CI=1.26 (1.18-1.34), p=.0001) or discharge (OR 95% CI=1.11 (1.05-1.18), p=0.0003). Prevalence of inappropriate prescription of drugs for peptic ulcer or GERD remained almost the same at admission and discharge. Inappropriate use of these drugs is related to the concomitant use of other drugs. Careful assessment of clinical conditions and stricter adherence to evidence-based guidelines are essential for a rational and cost-effective use of drugs for peptic ulcer or GERD.

Drug use during pregnancy may be dangerous to the fetus. There is high consumption of prescribed drugs among pregnant women. This condition may be much higher in developing countries. There is no sufficient evidence on prescribed drug use among pregnant women in Bahir Dar town. The aim of this study was to assess the level of prescribed drug use and associated factors among pregnant women attending antenatal care (ANC) service at government health centers in Bahir Dar city administration. Institution based cross sectional study was used. Data were collected from randomly selected 510 pregnant women. Data were analyzed using SPSS version 16.0. Back ward stepwise logistic regression model was used and p-values <0.05 were considered statistically significant. A total of 510 pregnant women were included in the study of which 88.4% were prescribed at least one drug during pregnancy. Nearly 11% of the pregnant women were prescribed with drugs from category D or X of the US-FDA risk classification.Prescribed drug use among pregnant women was more likely when the pregnancy is wanted, (AOR = 2.4, 95% CI: 1.3 - 4.6), if the mother had maternal illness (AOR = 8.5, 95% CI: 5.4-13.4), when the educational level of ANC provider is diploma (AOR = 2.7, 95% CI: 1.5-4.7) and when number of pregnancies is more (AOR =2.1, 95% CI: 1.3-3.3). Prescribed drug use including those with potential harm to the fetus during pregnancy was very high in Bahir Dar city administration. Prescribed drug use is more when the woman had illness, when the woman was multi gravida and when the educational level of ANC provider was low (diploma). It is important to upgrade providers' educational level and institute prevention of diseases like malaria to reduce the level of prescribed drug use during pregnancy.

The use of generic drugs has increased significantly in recent years. Since generic drugs are available at a lower cost, they provide an opportunity for savings in drug expenditure. Thus, use of generic drugs is encouraged especially in developing countries. There are only a few studies concerning the perceptions and attitudes of the healthcare providers and patients towards generic drug use. Methods The present study was conducted by a face to face questionnaire in the Kadikoy district of Istanbul in April 2010. From randomly chosen respondents, 68 pharmacists, 56 prescribers and 101 patients consented to participate in the study. Results Thirty one and 32 % of the pharmacists and prescribers, respectively, expressed that they believed that the generics did not differ from the original drugs, whereas only 24% of the patients believed so. Forty percent of the pharmacists and 82% of the prescribers told that they were unsure about the bioequivalence of the generics. Ten percent of the patients claimed that they immediately accept generic substitution by the pharmacist, while 26% accepted it if it was substituted by the prescriber. Cost was the most important factor taken into consideration about generic substitution (92% for prescribers; 83% for patients and 82% for pharmacists). Conclusions Our findings demonstrated that healthcare providers as well as the drug consumers have insufficient knowledge about generic drugs. Therefore, they should be better educated with respect to generic substitution. PMID:24155838

Health camp is generally organized to provide health care services to the people deprived of health care facilities. The aim of this project was to assess the proportions of disease among attendees of health camp and study the drug prescribing pattern in a free health camp. A case study was performed from 1 day health camp to determine the proportions of disease and drug prescribing pattern. Data collection was performed using log book maintained in the health camp and patient's demographic details, disease diagnosed and drug prescribed was obtained from same log book. A total of 317 patients were included in the study. The majority of the patients were in the range of 41-50 years. On the basis of study on ethnicity, Brahmins and Chettris, were found to be predominant ethnic groups with gastrointestinal disorders as the major disease. The total number of medications prescribed was 510, with non-steroidal anti-inflammatory drugs (NSAIDs) and antipeptic ulcer drugs being commonly prescribed. The average number of drugs per prescription and the percentage of antibiotics prescribed were 1.6 and 21.4%, respectively. It was observed that 96.8% of prescription was by generic names. Likewise, 100% of prescription included drugs from essential drug list. Majority of the patients were of working age group. Headache and fever were found to be the most prevalent cases and NSAIDs were the most commonly prescribed medications. The drug prescribing pattern of the free health camp complied with WHO recommended prescribing indicators.

Is it ethical to prescribe generic immunosuppressive drugs to renal transplant patients?

This review was conducted to determine the ethical acceptability of prescribing generic immunosuppressive drugs to renal transplant patients. The literature search was conducted using Pubmed and Google Scholar. The use of generic immunosuppressive drugs (ISDs) in transplantation is a controversial topic. There is a consensus among transplant societies that clinical data is lacking and that caution should be exercised. The reluctance to use generic ISDs in organ transplantation is partly related to the fact that most are "critical dose drugs", and that either low dosing or overdosing could have serious adverse consequences for both patients and society (i.e., the loss of scarce organs). In this paper, we examine the various ethical issues involved such as distributive justice, physician duties, risks versus benefits, conflict of interest, informed consent, and logistical and economic issues. Our analysis was limited by the paucity of clinical data on generic ISDs and the absence of health economics studies to quantify the benefits of prescribing generic ISDs. Our study led us to conclude that it would be ethical to prescribe generic ISDs provided certain conditions were met. These include regulatory safeguards to minimize the risks of substitution; education of patients; and further clinical and health economics studies to better inform clinicians, patients and society of the risks and costs related to drug substitution.

To determine the prevalence of potentially inappropriate medications (PIMs) and related factors through a comparative analysis of the Screening Tool of Older Person's Potentially Inappropriate Prescriptions (STOPP), the 2003 Beers criteria, and the 2012 AGS update of the Beers criteria. Cross-sectional. Primary care. Community-dwelling persons aged 65 and older who live on the island of Lanzarote, Spain (N = 407). Sociodemographic characteristics; independence in activities of daily living; cognitive function; Geriatric Depression Scale; clinical diagnoses; and complete data on indication, dosage, and length of drug treatments. One thousand eight hundred seventh-two prescriptions were examined, and the rate of PIMs was assessed with the three criteria. The primary endpoint was the percentage of participants receiving at least one PIM. Multivariate logistic regression was used to examine the factors related to PIMs. Potentially inappropriate medications were present in 24.3%, 35.4%, and 44% of participants, according to the 2003 Beers criteria, STOPP, and 2012 Beers criteria, respectively. The profile of PIMs was also different (the most frequent being benzodiazepines in both Beers criteria lists and aspirin in the STOPP). The number of drugs was associated with risk of prescribing PIMs in all three models, as was the presence of a psychological disorder in the 2003 Beers criteria (odds ratio (OR) = 2.07, 95% confidence interval (CI) = 1.26-3.40) and the 2012 Beers criteria (OR = 2.91, 95% CI = 1.83-4.66). The kappa for degree of agreement between STOPP and the 2012 Beers criteria was 0.35 (95% CI = 0.25-0.44). The 2012 Beers criteria detected the highest number of PIMs, and given the scant overlapping with the STOPP criteria, the use of both tools may be seen as complementary. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

A study on rational drug use was undertaken in nine health centres (HCs) and nine health stations (HSs) in Ethiopia. Prescribing, patient care and facility specific factors were measured using drug use indicators. Prescribing patterns of drugs were also assessed. With only few exceptions, the drug use indicators in HCs and HSs and between retrospective and prospective studies were similar despite differences in manpower and facilities. The average consultation time (in minutes) in HSs and HCs was 5.1 +/- 0.8 and 5.8 +/- 1.06, respectively. The dispensing time (in minutes) was 1.5 +/- 0.7 in HSs and 1.9 +/- 0.6 in HCs. Both patient care indicators seem to be adequate to influence patient satisfaction to the overall health service and patient knowledge of important dosage instructions. Most drugs (more than 89% in HCs and 71% in HSs) were actually dispensed from the health facilities and labelling was satisfactory. Prescribing by generic names (average: 75% in HCs and 83% in HSs) was encouraging. While the availability of key drugs was ensured, essential documents were missing in most facilities or they were unpopular for use, and those available required revision and updating. Polypharmacy in which the number of drugs/encounter was < 2.5 was minimal, but that a large proportion of the prescriptions contained two or more drugs could result in adverse drug-drug interactions. The most frequently prescribed drugs were anti-infectives and analgesics accounting for over 76% in HCs and 82% in HSs and in most cases they are probably prescribed with little justification. The exposure of patients to antibiotics (average: 60% in HCs and 65% in HSs) was unacceptably high to justify epidemiological trends. The high exposure of patients to injections, especially in the HSs (over 37%), should be seen from the health and economic points of view. The results revealed priority areas for intervention. They also provide standard references to compare drug use situations and their

Prescription drug misuse and abuse has reached epidemic levels in the U.S., and stands as a leading cause of death. As the primary gatekeepers to the medications contributing to this epidemic, it is critical to understand the views of licensed health care professionals. In this study, we examine health care professionals' concern regarding prescription drug abuse in their communities and the impact their concern has had on their prescribing and dispensing practices. An online survey of licensed health care providers. Conducted in Indiana. This study was a state-wide evaluation of Indiana's prescription drug monitoring program. The questionnaire asked respondents how concerned they were about prescription drug abuse in their community. Variation in the level of concern was examined using ordinary least squares regression and information about the respondents' demographic background and clinical experience. In addition, we used logistic regression to examine whether concern was associated with changing prescribing and/or dispensing behavior. The majority of providers indicated they were "moderately" or "extremely concerned" about prescription drug abuse in their communities. The level of concern, however, varied significantly by profession, with pharmacists, physicians, nurse practitioners/physician assistants being more concerned than dentists. Additional analyses indicate that providers with higher levels of concern were those who also reported recently changing their prescribing and/or dispensing behavior. The voluntary nature and geographical focus of the study limits the generalizability of the findings. Concern about prescription drug abuse is generally high across the major health care professions; however, a significant minority of providers, particularly among dentists, expressed little or no concern about the epidemic. Increasing health care providers' general level of concern about prescription drug abuse may be an effective public health tool for

Background When initiated by a health plan, academic detailing can be used to change prescribing practices, which can lead to increased safety and savings. Objective To evaluate the impact of academic detailing on prescribing and prescription drug costs of cefixime to a health plan. Methods A prospective intervention study was carried out that evaluated the prescribing practices and prescription drug costs of cefixime. A total of 11 prescribers were detailed by 1 pharmacist between August 2014 and March 2015. Two of the 11 prescribers did not respond to the academic detailing and were not followed up. The physicians' prescribing habits and prescription costs were compared before and after detailing to evaluate the effectiveness of the intervention. Data were collected for approximately 5 months before and after the intervention. Each prescriber served as his or her own control. Results Overall, an approximate 36% reduction in the number of cefixime prescriptions written and an approximate 20% decrease in prescription costs was seen with academic detailing compared with the year before the intervention. In 9 of 11 (82%) prescribers, intervention with academic detailing was successful and resulted in fewer prescriptions for cefixime during the study period. Conclusion Academic detailing had a positive impact on prescribing, by decreasing the number of cefixime prescriptions and lowering the drug costs to the health plan. PMID:28626509

While evidence on implementation of medication safety strategies is increasing, reasons for selecting and relinquishing distinct strategies and details on implementation are typically not shared in published literature. We aimed to collect and structure expert information resulting from implementing medication safety strategies to provide advice for decision-makers. Medication safety experts with clinical expertise from thirteen hospitals throughout twelve European and North American countries shared their experience in workshop meetings, on-site-visits and remote structured interviews. We performed an expert-based, in-depth assessment of implementation of best-practice strategies to improve drug prescribing and drug administration. Workflow, variability and recommended medication safety strategies in drug prescribing and drug administration processes. According to the experts, institutions chose strategies that targeted process steps known to be particularly error-prone in the respective setting. Often, the selection was channeled by local constraints such as the e-health equipment and critically modulated by national context factors. In our study, the experts favored electronic prescribing with clinical decision support and medication reconciliation as most promising interventions. They agreed that self-assessment and introduction of medication safety boards were crucial to satisfy the setting-specific differences and foster successful implementation. While general evidence for implementation of strategies to improve medication safety exists, successful selection and adaptation of a distinct strategy requires a thorough knowledge of the institute-specific constraints and an ongoing monitoring and adjustment of the implemented measures.

To investigate the extent and how cough mixtures are prescribed, and what conditions or specific groups of people would contribute to its prescription in Hong Kong. Using diagnosis and drug data obtained from logbooks submitted by participants in the diploma in family medicine course between 1999 and 2003, we selected and analysed all patients with a diagnosis of cough or cough-related illnesses as well as cough mixtures that were used to treat them. This study confirmed that cough-related illnesses were common in the Hong Kong primary care setting and cough mixtures were used quite liberally irrespective of the patients' age and sex. Combination preparations accounted for over half of the prescriptions and cough mixture was used less in severe cases when antibiotics were given. Private doctors working in the public sector. Given the current health care system, inappropriate and over-prescribing of cough mixtures can be improved by promoting health education and awareness among patients seeking medical help for this common medical condition.

Introduction: Acute respiratory distress syndrome (ARDS) is characterized by acute respiratory failure and is associated with wide range of clinical disorders. Controversy prevails over the pharmacological intervention in this disease. The aim of the study was to observe the prescribing pattern of drugs in patients with ARDS managed at a tertiary care hospital. Materials and Methods: This observational study was conducted at tertiary care hospital in India. Data of patients admitted from January 2010 to December 2012 was collected. Patients aged more than 18 years admitted in ICU, who were diagnosed to have ARDS during the study period, were included. A total of 150 patients of ARDS were selected. Data was collected as per the pre designed proforma and it included patients’ age, gender, clinical disorders precipitating ARDS, prescribing pattern of drugs and outcome. The data of the subjects was collected till discharge from hospital or death. Results: Infection was the cause of ARDS in 81.3% (n=122) of subjects. Antibiotics were prescribed in all the subjects and beta-lactams were prescribed in 97.3% (n=146). 41.3% (n=62) were prescribed corticosteroids, 39.3% (n=59) diuretics and 89.3% (n=134) intravenous fluids. Conclusion: The outcome of patients on different pharmacological treatment did not show any statistically significant difference. PMID:25859465

ABSTRACT Objective: to identify and summarize studies examining both drug-drug interactions (DDI) and adverse drug reactions (ADR) in older adults polymedicated. Methods: an integrative review of studies published from January 2008 to December 2013, according to inclusion and exclusion criteria, in MEDLINE and EMBASE electronic databases were performed. Results: forty-seven full-text studies including 14,624,492 older adults (≥ 60 years) were analyzed: 24 (51.1%) concerning ADR, 14 (29.8%) DDI, and 9 studies (19.1%) investigating both DDI and ADR. We found a variety of methodological designs. The reviewed studies reinforced that polypharmacy is a multifactorial process, and predictors and inappropriate prescribing are associated with negative health outcomes, as increasing the frequency and types of ADRs and DDIs involving different drug classes, moreover, some studies show the most successful interventions to optimize prescribing. Conclusions: DDI and ADR among older adults continue to be a significant issue in the worldwide. The findings from the studies included in this integrative review, added to the previous reviews, can contribute to the improvement of advanced practices in geriatric nursing, to promote the safety of older patients in polypharmacy. However, more research is needed to elucidate gaps. PMID:27598380

Little is known about the impact of direct-to-consumer advertising (DTCA) on appropriate versus inappropriate prescribing. Aromatase inhibitor (AI) therapy for breast cancer provides an ideal paradigm for studying this issue, because AIs have been the focus of substantial DTCA, and because they should only be used in postmenopausal women, age can serve as a simple surrogate marker of appropriateness. Data regarding national DTCA spending for the AIs were obtained from TNS Multimedia; hormonal therapy prescription data were obtained from IMS Health. Time series analyses were performed to characterize the association between monthly changes in DTCA spending for the AIs and monthly changes in the proportion of all new hormonal therapy prescriptions represented by the AIs from October 2005 to September 2007. Analyses were stratified by age, considering prescriptions for women ≤ 40 (likely premenopausal) to be inappropriate and those for women > 60 (likely postmenopausal) to be appropriate. Monthly dollars spent on AI-associated DTCA varied considerably ($118,600 to $22,019,660). Time series analysis revealed that for every million dollars spent on DTCA for the AIs, there was an associated increase 3 months later in the new AI prescription proportion of 0.15% for all ages (P < .0001) and 0.18% for those > 60 years (P < .0001), but no significant change for those ≤ 40 at any time from 0 to 6 months. DTCA for the AIs was associated with increases in appropriate prescriptions with no significant effect on inappropriate prescriptions, suggesting that DTCA may not foster inappropriate medication use for certain drug classes.

Adverse drug events (ADEs), which can be especially problematic in older adults, often can be prevented by detecting potential risk factors. Sociopsychological factors such as concerns and beliefs about medicines (patients' anxieties about the harmful effects of prescribed medications) may also be risk factors related to self-reported ADEs, even when considering clinical variables such as receiving an inappropriate medication. This study was designed to quantify the use of inappropriate medications among older adult outpatients and to determine whether an association exists between the use of inappropriate medications, concerns and beliefs about medicines, and self-reported ADEs. This cross-sectional, Internet-based survey of Medicare beneficiaries was conducted in 2007. Harris Interactive, a New York-based marketing research firm, invited participants from their online panel who were >or=65 years of age, residents of the United States, and enrolled in the Medicare health plan to participate in the survey. The updated Beers criteria and a modified version of the Assessing Care of Vulnerable Elders quality indicators were used to determine the appropriateness of medications. Respondents' concerns about their medicines were assessed using items from a validated scale such as "Having to take medicines worries me" and "I sometimes worry about the long-term effects of my medicines." To establish self-reported ADEs, respondents were asked, "Did you see a doctor about any side effects, unwanted reactions, or other problems from medicines you were taking in the past year?" Of the 1024 panelists who responded to the survey, 874 provided all of the information required for analysis. The respondents who were included in the analyses ranged in age from 65 to 94 years; 56.6% were female, 94.4% were white, and 20.3% self-reported an ADE. The frequency of patients receiving either an inappropriate medication or a medication that failed a quality indicator was 45.8%. Stronger

Irrational and inconsistent drug prescription has considerable impact on morbidity, mortality, health service utilization, and community burden. However, few studies have addressed the methodology of processing the information contained in these drug orders used to study the quality of drug prescriptions and prescriber behavior. We present a comprehensive set of quantitative indicators for the quality of drug prescriptions which can be derived from a drug order. These indicators were constructed using explicit a priori criteria which were previously validated on the basis of scientific data. Automatic computation is straightforward, using a relational database system, such that large sets of prescriptions can be processed with minimal human effort. We illustrate the feasibility and value of this approach by using a large set of 23,000 prescriptions for several diseases, selected from a nationally representative prescriptions database. Our study may result in direct and wide applications in the epidemiology of medical practice and in quality control procedures.

Misuse of antibiotics is largely responsible for the emergence of bacterial resistance. Children represent a subset of the population who frequently receive antibiotics. The objectives were to calculate the frequency of antibiotic prescriptions that do not comply with best practice recommendations in paediatrics primary care and to examine the thoughts and feelings of physicians and parents about antibiotic prescription and recommendations from the national health authorities. We included children admitted at the paediatric emergency room (PER) of the NANTES university hospital between June 2011 and October 2012 and who were under antibiotic drugs. Two independent experts evaluated the compliance with the national recommendations. Parents and general practitioner (GP) who prescribed the antibiotic before admission to PER were called to collect their thoughts and feeling about antibiotic prescription. The median age of the 88 included children was 2.8 years. The upper respiratory tract infection motivated the prescription of antibiotic in 59%. Seventy-six per cent of the prescriptions analysed were inappropriate, 72% of the antibiotics had a too broad spectrum, and one-third was not indicated. Ninety-one per cent of the interviewed parents thought that the antibiotic prescribed to their child was adequate. Among the 77 prescribing GP who were called, 33% agreed that they lacked time during consultation to explain to parents that no antibiotics were required. Antibiotic prescriptions were too often inadequate in this sample of children admitted in a French PER. Efforts have to be made with physicians and general public to optimize the antibiotic drug use. © The Author(s) 2016.

The drug use process suffers from problems related to quality and cost that have not responded well to administrative or educational interventions. In many cases, attempts to improve the quality of physician prescribing have been clumsy, often based on intuition. This article begins by describing the drug use process and the role of prescribing in that process. In the following section, we describe what is known about how physicians make drug choice decisions. The paper concludes with suggestions, based on evidence, about the design of strategies for influencing prescribing.

The rationalization of the prescription and the good use of the drugs generally constitute a major problem in the health facilities. The present survey led in November 2002 in Mali assessed the practices of prescription and the use of the drugs by the populations. The indicators of drugs use rational have been measured from 600 drawn prescriptions randomly select at the level of 20 community health center (CSCOM) retained at random in the regions of Ségou, Sikasso, Mopti and the District of Bamako. The means of drugs by order (2.8), the percentages of prescription with antibiotic (61.6%) and injectable drugs (35%) are raised in relation to the normative values of WHO (Wold Health Organization). The rate of conformity to the treatments standardized estimated on exploitation of consultations registers in the centers is estimated to 0.5% for the simple diarrhoea, 13.5% for the acute respiratory infections (ARI) without pneumonia and 60.5% for the pneumonia. On 293 patients in the households our survey permitted to estimate to 84.6% the observance of the treatment by the persons having bought the prescribed drugs totality. The percentage of antibiotics prescription and injectable drugs, and the big insufficiency in the non respect of the treatment standard constitutes some practices potentially to high risk justifying the necessity of an urgent training to the rational prescription.

The financial accessibility of antimicrobial drugs to the outpatient community in Canada is governed at the provincial level through formularies. Each province may choose to list particular drugs or impose restriction criteria on products in order to guide prescribing and/or curtail costs. Although changes to formularies have been shown to change patterns in the use of individual products and alter costs, no comparison has been made among the provincial antimicrobial formularies with regards to flexibility/stringency, or an assessment of how these formularies impact overall antimicrobial use in the provinces. To summarize provincial antimicrobial formularies and assess whether their relative flexibility/stringency had a statistical impact upon provincial prescription volume during a one year period. Provincial drug plan formularies were accessed and summarized for all prescribed antimicrobials in Canada during 2010. The number of general and restricted benefits for each plan was compiled by antimicrobial classification. Population-adjusted prescription rates for all individual antimicrobials and by antimicrobial class were obtained from the Canadian Integrated Program for Antimicrobial Resistance Surveillance. Correlations between the number of general benefits, restricted benefits, and total benefits with the prescription rate in the provinces were assessed by Spearman rank correlation coefficients. Formularies varied considerably among the Canadian provinces. Quebec had the most flexible formulary, offering the greatest number of general benefits and fewest restrictions. In contrast, Saskatchewan's formulary displayed the lowest number of general benefits and most restrictions. Correlation analyses detected a single significant result; macrolide prescription rates decreased as the number of general macrolide benefits increased. All other rates of provincial antimicrobial prescribing and measures of flexibility/stringency revealed no significant correlations

Following Food and Drug Administration (FDA) approval, many drugs are prescribed for non-FDA-approved ("off-label") uses. If substantial evidence supports the efficacy and safety of off-label indications, manufacturers can pursue formal FDA approval through supplemental new drug applications (sNDAs). We evaluated the effect of FDA determinations on pediatric sNDAs for antipsychotic drugs on prescribing of these products in children. Retrospective, segmented time-series analysis using new prescription claims during 2003-2012 for three atypical antipsychotics (olanzapine, quetiapine, ziprasidone). FDA approved the sNDAs for pediatric use of olanzapine and quetiapine in December 2009, but did not approve the sNDA for pediatric use of ziprasidone. During the months before FDA approval of its pediatric sNDA, new prescriptions of olanzapine decreased for both children and adults. After FDA approval, the increase in prescribing trends was similar for both age groups (P = 0.47 for schizophrenia and bipolar disorder; P = 0.37 for other indications). Comparable decreases in use of quetiapine were observed between pediatrics and adults following FDA approval of its pediatric sNDA (P = 0.88; P = 0.63). Prescribing of ziprasidone decreased similarly for pediatric and adult patients after FDA non-approval of its pediatric sNDA (P = 0.61; P = 0.79). The FDA's sNDA determinations relating to use of antipsychotics in children did not result in changes in use that favored the approved sNDAs and disfavored the unapproved sNDA. Improved communication may help translate the agency's expert judgments to clinical practice.

The influence of patient expectations and demands on the decisions of prescribers in general practice has been associated with irrational prescribing and lack of evidence-based practice. However, to our knowledge, no one has investigated patient pressure to prescribe in secondary care. To investigate the influences on hospital prescribers' decisions by exploring what they found uncomfortable when prescribing. Qualitative interviews with 48 prescribers of varying seniority from 4 hospitals were conducted. Interviews were based on the critical incident technique, and prescribers were asked, before an interview, to remember any uncomfortable prescribing decisions that they had made; these were then discussed in detail during an interview. This approach allowed the interviewer to explore the more general influences on the decision to prescribe. Interviews were tape recorded and transcribed verbatim. A grounded theory approach to data analysis was taken. Prescribers discussed various factors that could provoke feelings of discomfort when prescribing. Pressure on the prescribing decision from patients, relatives, or carers was a major theme, and more than half of interviewees discussed discomfort caused by such perceived pressure on the prescribing decision. How prescribers dealt with this pressure varied with seniority and the type of relationship that they had fostered with the patient. Nearly half of all incidents of patient pressure resulted in the patient being prescribed the medication they requested. Yet, many of these requests were deemed inappropriate by the prescriber. Their reasons for capitulation varied but included maintaining a good prescriber-patient relationship and avoiding conflict in the wider health care team. Pressure from patients, relatives, or carers was an uncomfortable influence on these hospital prescribers' prescribing decisions. Increasingly consumer-driven health care will intensify these issues in the future. We advocate further research

Little is known about the decision pathway that family physicians (FP) take in considering drug therapy for their asthma patients. This study aimed to explore the factors that influence FPs' decisions in prescribing medications for their asthma patients. A qualitative method using focus group discussions (FGD) was used to gather qualitative data based on a semi-structured topic guide from FPs of different training backgrounds and practices. 29 Singapore FPs working as private general practitioners (GP), polyclinic doctors and locums were recruited into five FGDs. The FPs' asthma drug prescription decisions were related to the FPs' medical training and acquisition of asthma-related information and updates. Uncertainty of disease diagnosis, patients' beliefs and their perceptions of the disease and treatment, as well as the FPs' concerns about drug side effects, were significant considerations for the participants. Costs related to differential subsidies in the consultation fees and drugs between public polyclinics and GP clinics in the local primary healthcare system, was a key factor in influencing the FPs' asthma drug treatment decisions. FPs' asthma drug prescribing behaviour is influenced by their medical training, disease definition, patient factors and drug costs in the context of the local primary healthcare system and policy.

Antihypertensive medications are widely prescribed by doctors and heavily promoted by the pharmaceutical industry. Despite strong evidence of the effectiveness and cost-effectiveness of thiazide diuretics, trends in both promotion and prescription of antihypertensive drugs favour newer, less cost-effective agents. Observational evidence shows correlations between exposure to pharmaceutical promotion and less ideal prescribing. Our study therefore aimed to determine whether print advertisements for antihypertensive medications promote quality prescribing in hypertension. We performed a cross-sectional study of 113 advertisements for antihypertensive drugs from 4 general practice-oriented Australian medical publications in 2004. Advertisements were evaluated using a quality checklist based on a review of hypertension management guidelines. Main outcome measures included: frequency with which antihypertensive classes were advertised, promotion of thiazide class drugs as first line agents, use of statistical claims in advertisements, mention of harms and prices in the advertisements, promotion of assessment and treatment of cardiovascular risk, promotion of lifestyle modification, and targeting of particular patient subgroups. Thiazides were the most frequently advertised drug class (48.7% of advertisements), but were largely promoted in combination preparations. The only thiazide advertised as a single agent was the most expensive, indapamide. No advertisement specifically promoted any thiazide as a better first-line drug. Statistics in the advertisements tended to be expressed in relative rather than absolute terms. Drug costs were often reported, but without cost comparisons between drugs. Adverse effects were usually reported but largely confined to the advertisements' small print. Other than mentioning drug interactions with alcohol and salt, no advertisements promoted lifestyle modification. Few advertisements (2.7%) promoted the assessment of cardiovascular risk

The quality of drug therapy is an important issue for nursing homes. This study aimed to assess the prevalence of polypharmacy and potentially inappropriate medications (PIMs) in a large sample of nursing home residents by using the data recorded during the preparation of pill dispensers. This is a cross-sectional study that included 451 nursing homes across France. Information about the medications received by the 30,702 residents (73.8% women) living in these nursing homes was extracted from the system that assists in the preparation of pill dispensers in pharmacies. The anonymized database included age, sex, and medications prescribed to residents, as well as nursing home characteristics (capacity, legal status). Factors associated with excessive polypharmacy (≥10 different drugs) and PIMs according to the Laroche list were studied using multilevel regression models. The average number of drugs prescribed was 6.9 ± 3.3, and excessive polypharmacy concerned 21.1% of the residents (n = 6468). According to the Laroche list, 47.4% of residents (n = 14,547) received at least one PIM. Benzodiazepines (excessive doses, long-acting benzodiazepines, and combination of benzodiazepines) and anticholinergic medications (hydroxyzine, cyamemazine, alimemazine) accounted for a large part of PIMs. Individual characteristics (age, gender) influenced the risk of receiving PIMs whereas nursing home characteristics (capacity, legal status) influenced the risk of excessive polypharmacy. This study shows that polypharmacy and PIMs remain highly prevalent among nursing home residents. Main PIMs concerned psychotropic and anticholinergic medications.

Background A clinical decision support system (CDSS) linked to the computerized physician order entry may help improve prescription appropriateness in inpatients with renal insufficiency. Objective To evaluate the impact on prescription appropriateness of a CDSS prescriber alert for 85 drugs in renal failure patients. Setting Before-after study in a 975-bed academic hospital. Method Prescriptions of patients with renal failure were reviewed during two comparable periods of 6 days each, before and after the implementation of the CDSS (September 2009 and 2010). Main outcome measure The proportion of inappropriate dosages of 85 drugs included in the CDSS was compared in the pre- and post-implementation group. Results Six hundred and fifteen patients were included in the study (301 in pre- and 314 in post-implementation periods). In the pre- and post-implementation period, respectively 2882 and 3485 prescriptions were evaluated, of which 14.9 and 16.6% triggered an alert. Among these, the dosage was inappropriate in respectively 25.4 and 24.6% of prescriptions in the pre- and post-implementation periods (OR 0.97; 95% CI 0.72-1.29). The most frequently involved drugs were paracetamol, perindopril, tramadol and allopurinol. Conclusion The implementation of a CDSS did not significantly reduce the proportion of inappropriate drug dosages in patients with renal failure. Further research is required to investigate the reasons why prescribers override alerts. Collaboration with clinical pharmacists might improve compliance with the CDSS recommendations.

The prevalence of psychotropic and nonpsychotropic drug prescriptions in institutions and community residential facilities in 1978-79 was assessed. The data were gathered as an incidental part of a comprehensive national interview study of the characteristics of residential facilities and their residents. The study included 2271 retarded individuals in 236 residential facilities in the US. Facilities were selected through a 2-stage probability sample design in such a way that the probability of a facility's selection was proportionate to its size (number of residents) and so that the distribution of sample facilities across census regions and size classes was in close agreement with the distribution of facilities nationally. Interviews at 75 institutions and 161 private facilities were conducted between September 1978 and April 1979. Demographic information about individual residents, including date of birth, date of admission, previous type of residential placement, age, height, weight, diagnosed degree of retardation, and diagnosis of epilepsy, autism, or mental illness, was obtained from each resident's records. The staff person most familiar with each resident was then identified and interviewed about the resident. Care persons were asked whether and for what purpose drugs were prescribed for each resident. 75.8% of institutionalized residents and 54.3% of community facility residents were reported to be receiving at least 1 type of regularly prescribed medication. Percentages reported for specific drugs should be considered minimums, because drug names were not always elicited if the drug's purpose was known. Drugs not named, but reported to be prescribed for a chronic health condition, epilepsy, a psychiatric problem, for sleeping, or for birth control, were listed with "other" within tentative categories. Multiple regression was used to examine the relationships among drug use and several resident and facility characteristics. The institutionalized and

Several lists of potentially inappropriate medication (PIM) for elderly patients have been developed worldwide in recent years. Those lists intend to reduce prescriptions of drugs that carry an unnecessarily high risk of adverse drug events in elderly patients. In 2010, an expert panel published the PRISCUS list for the German drug market. This study calculates the amount of drug reimbursement for PIM in Germany and potential cost effects from the perspective of statutory health insurance when these are replaced by the substitutes recommended by the PRISCUS list. Register-based data for the 30 top-selling drugs on the PRISCUS list in 2009 for patients greater than or equal to 65 years of age were provided by the Scientific Institute of the German Local Health Care Fund. We calculated the percentage of sales and defined daily doses for patients greater than or equal to 65 years of age compared with the total statutory health insurance population. Reimbursement costs for the recommended substitutions were estimated by considering different scenarios. In 2009, drug reimbursement for the 30 top-selling PIM prescribed to patients greater than or equal to 65 years of age were calculated to be €305.7 million. Prescribing the recommended substitution medication instead of PIM would lead to an increased total reimbursement cost for the German health care system ranging between from €325.9 million to €810.0 million. The results show that the substitution of PIM by medication deemed to be more appropriate for the elderly comes along with additional costs. Consequently, there is no short-term incentive for doing so from a payer perspective. Future studies have to consider the long-term effects and other sectors.

Interpersonal communication is inherent in a majority of strategies seeking to engage prescriber and pharmacist health care professionals (HCPs) in the reduction and prevention of prescription drug abuse (PDA). However, research on HCP PDA communication behavioral engagement and factors that influence it is limited. This study quantitatively examined communication behaviors and trait-level communication metrics, and qualitatively described prescription drug abuse-related communication perceptions and behaviors among primary care prescribers and community pharmacists. Five focus groups (N = 35) were conducted within the Appalachian Research Network (AppNET), a rural primary care practice-based research network (PBRN) in South Central Appalachia between February and October, 2014. Focus groups were structured around the administration of three previously validated trait-level communication survey instruments, and one instrument developed by the investigators to gauge HCP prescription drug abuse communication engagement and perceived communication importance. Using a grounded theory approach, focus group themes were inductively derived and coded independently by study investigators. Member-checking interviews were conducted to validate derived themes. Respondents' trait-level communication self-perceptions indicated low communication apprehension, high self-perceived communication competence, and average willingness to communicate as compared to instrument specific criteria and norms. Significant variation in HCP communication behavior engagement was noted specific to PDA. Two overarching themes were noted for HCP-patient communication: 1) influencers of HCP communication and prescribing/dispensing behaviors, and 2) communication behaviors. Multiple sub-themes were identified within each theme. Similarities were noted in perceptions and behaviors across both prescribers and pharmacists. Despite the perceived importance of engaging in PDA communication, HCPs reported

Objectives Adherence to safer nonsteroidal anti-inflammatory drug (NSAID) prescribing strategies remains low, despite their acceptance as markers of high-quality care and their aggressive dissemination. This study describes the taxonomy of methods used by pharmaceutical companies to influence physicians’ NSAID prescribing behaviors and elicits physicians’ perceptions of and counter-balances to these influences. Study Design In-depth interviews analyzed using the constant comparative method of qualitative data analysis. Methods Qualitative interviews were conducted with physicians representing various clinical specialties. Interviews were transcribed and coded inductively using grounded theory. Recruitment was stopped at 25 participants after the attainment of thematic saturation, when no new concepts emerged from ongoing analysis of consecutive interviews. Results Physicians described a variety of influences that shaped their NSAID prescribing behaviors, including detailing and direct contact with pharmaceutical representatives, requests from patients inspired by direct-to-consumer advertisements, and marketing during medical school and residency training. Physicians described practice guidelines, peer-reviewed evidence and opinions of local physician experts as important counterweights to pharmaceutical company influence. Local physician experts interpreted and provided context for new clinical evidence, practice guidelines and NSAID related marketing. Conclusions The social and communicative strategies used by pharmaceutical companies can be adapted to improve physicians’ adoption of guidelines for safer NSAID prescribing. The communicative interactions between local experts and other physicians who prescribe NSAIDs may be the critical target for future interventions to promote safer NSAID prescribing. PMID:19341315

Educational Outreach to Opioid Prescribers: The Case for Academic Detailing.

PubMed

Trotter Davis, Margot; Bateman, Brian; Avorn, Jerry

2017-02-01

Nonmedical use of opioid medications constitutes a serious health threat as the rates of addiction, overdoses, and deaths have risen in recent years. Increasingly, inappropriate and excessively liberal prescribing of opioids by physicians is understood to be a central part of the crisis. Public health officials, hospital systems, and legislators are developing programs and regulations to address the problem in sustained and systematic ways that both insures effective treatment of pain and appropriate limits on the availability of opioids. Three approaches have obtained prominence as means of avoiding excessive and inappropriate prescribing, including: providing financial incentives to physicians to change their clinical decision through pay-for-performance contracts, monitoring patient medications through Prescription Drug Monitoring Programs, and educational outreach to physicians. A promising approach to educational outreach to physicians is an intervention known as "academic detailing." It was developed in the 1980s to provide one-on-one educational outreach to physicians using similar methods as the pharmaceutical industry that sends "detailers" to market their products to physician practices. Core to academic detailing, however, is the idea that medical decisions should be based on evidence-based information, including managing conditions with updated assessment measures, behavioral, and nonpharmacological interventions. With the pharmaceutical industry spending billions of dollars to advertise their products, individual practitioners can have difficulty gathering unbiased information, especially as the number of approved medications grows each year. Academic detailing has successfully affected the management of health conditions, such as atrial fibrillation, chronic obstructive pulmonary disease, and recently, has targeted physicians who prescribe opioids. This article discusses the approach as a potentially effective preventative intervention to address the

Background. Proton pump inhibitors (PPIs) are currently the most effective agents for acid-related disorders. However, studies show that 25–75% of patients receiving intravenous PPIs had no appropriate justification, indicating high rates of inappropriate prescribing. Objective. To examine the appropriate use of intravenous PPIs in accordance with guidelines and the efficacy of a prescribing awareness intervention at an Asian teaching institution. Setting. Prospective audit in a tertiary hospital in Malaysia. Method. Every 4th intravenous PPI prescription received in the pharmacy was screened against hospital guidelines. Interventions for incorrect indication/dose/duration were performed. Patients’ demographic data, medical history and the use of intravenous PPI were collected. Included were all adult inpatients prescribed intravenous PPI. Main Outcome Measure. Proportion of appropriate IV PPI prescriptions. Results. Data for 106 patients were collected. Most patients were male [65(61.3%)], Chinese [50(47.2%)], with mean age ± SD = 60.3 ± 18.0 years. Most intravenous PPI prescriptions were initiated by junior doctors from the surgical [47(44.3%)] and medical [42(39.6%)] departments. Only 50/106(47.2%) patients had upper gastrointestinal endoscopy/surgery performed to verify the source of bleeding.

Background. Proton pump inhibitors (PPIs) are currently the most effective agents for acid-related disorders. However, studies show that 25-75% of patients receiving intravenous PPIs had no appropriate justification, indicating high rates of inappropriate prescribing. Objective. To examine the appropriate use of intravenous PPIs in accordance with guidelines and the efficacy of a prescribing awareness intervention at an Asian teaching institution. Setting. Prospective audit in a tertiary hospital in Malaysia. Method. Every 4th intravenous PPI prescription received in the pharmacy was screened against hospital guidelines. Interventions for incorrect indication/dose/duration were performed. Patients' demographic data, medical history and the use of intravenous PPI were collected. Included were all adult inpatients prescribed intravenous PPI. Main Outcome Measure. Proportion of appropriate IV PPI prescriptions. Results. Data for 106 patients were collected. Most patients were male [65(61.3%)], Chinese [50(47.2%)], with mean age ± SD = 60.3 ± 18.0 years. Most intravenous PPI prescriptions were initiated by junior doctors from the surgical [47(44.3%)] and medical [42(39.6%)] departments. Only 50/106(47.2%) patients had upper gastrointestinal endoscopy/surgery performed to verify the source of bleeding. Unexplained abdominal pain [81(76.4%)] was the main driver for prescribing intravenous PPIs empirically, out of which 73(68.9%) were for suspected upper gastrointestinal bleed. Overall, intravenous PPI was found to be inappropriately prescribed in 56(52.8%) patients for indication, dose or duration. Interventions on the use of intravenous PPI were most effective when performed by senior doctors (100%), followed by clinical pharmacists (50%), and inpatient pharmacists (37.5%, p = 0.027).

Chinese regulation of off-label use of drugs.

China has significant gaps and weaknesses in its regulatory oversight of the off-label use of drugs. As in the United States, the off-label prescribing of drugs is not prohibited in China if there is a sound scientific basis. Physicians are allowed to prescribe off-label drugs based on their medical judgment if they follow certain requirements. There is some constraint on the right to prescribe by the imposition of malpractice liability if patients are harmed from improper off-label prescribing. However, damages awarded to successful plaintiffs are usually insignificant compared to malpractice damage awards in the U.S. Advertisement of off-label use is prohibited in China. All drug advertisements in China are subject to pre-approval, and must be based on information included in the approved package insert. However, the term "advertisement" is poorly defined. As a result, non-advertisement promotion of drugs for on-label or off-label use exist in a unregulated gray area. To better address the problem of inappropriate off-label promotion and use, China should (i) regulate both drug advertisements and non-advertisement promotion under a standard requiring off-label use to have a sound scientific basis, (ii) introduce harsher regulatory penalties, and (iii) increase compensation available for victims of medical malpractice. Such reform would not only discourage improper off-label use by introducing penalties (or increasing existing penalties) for improper promotion, but would also provide reasonable compensation for victims harmed by off-label use.

The purpose of this paper was to compare outpatient consumption and quality of psychotropic drug prescribing between Croatia and Bosnia & Herzegovina 2006-2010. Data on drug utilization from Zagreb Municipal Pharmacy and Sarajevo Public Pharmacy were used to calculate the number of defined daily doses (DDD) and DDD per 1000 inhabitants per day (DDD/TID) using the WHO Anatomical-Therapeutic-Chemical methodology. Total utilization of psychopharmaceuticals increased in both cities; however, it was higher in Zagreb than in Sarajevo throughout the study period. The utilization of psycholeptics increased in Zagreb by 2.4% (from 74.5 to 76.3 DDD/TID) and in Sarajevo by 3.8% (from 62.4 to 64.8 DDD/TID). The utilization of anxiolytics decreased in Zagreb by 2.1% and in Sarajevo by even 18.7%. The utilization of antidepressants increased in both cities with predominance of SSRI over TCA utilization, greater in Sarajevo (96.6%) than in Zagreb (10.2%). The anxiolytic/antidepressant ratio decreased by 11.1% in Zagreb (from 2.87 to 2.55) and by 58.7% in Sarajevo (from 5.66 to 2.34). Outpatient utilization of antipsychotics increased significantly in Sarajevo, predominated by typical ones, whereas in Zagreb the utilization of antipsychotics was stable, predominated by atypical ones. In Croatia and Bosnia & Herzegovina, there was an obvious tendency to follow western trends in drug prescribing, as demonstrated by the increased use of antidepressants and reduced use of anxiolytics. Despite some improvement observed in the prescribing quality, high use of antipsychotics with dominance of typical antipsychotics in Sarajevo points to the need of prescribing guidelines for antipsychotics.

To describe the use and determine the prevalence of off-label and unlicensed drug use prescribing in a pediatric intensive care unit in a Southeastern Brazilian hospital Cross-sectional study of inpatients in a pediatric intensive care unit from May 2008 through January 2009. The classification according to the Brazilian regulatory agency (Agência de Vigilância Sanitária - Anvisa) approval criteria was based on the Anvisa electronic package insert list, Pharmaceuticals Dictionary, and the analysis was conducted through R software. We analysed 1,054 prescription items for 73 patients. Females predominated (52%), and the patients' age ranged from 0 to 16 years. Among the prescribed items, 23.4% were off-label, 12.6% were unlicensed, 1.4% were both off-label and unlicensed, 86% had at least one item off-label, and 67% had at least one unlicensed drug. The most frequently prescribed therapeutic groups were systemic anti-bacterial, analgesic, psycholeptic, and antiasmathic agents. The current study results confirm the high prevalence of unlicensed and off-label drug use in a pediatric intensive care unit.

European medical students should have acquired adequate prescribing competencies before graduation, but it is not known whether this is the case. In this international multicenter study, we evaluated the essential knowledge, skills, and attitudes in clinical pharmacology and therapeutics (CPT) of final-year medical students across Europe. In a cross-sectional design, 26 medical schools from 17 European countries were asked to administer a standardized assessment and questionnaire to 50 final-year students. Although there were differences between schools, our results show an overall lack of essential prescribing competencies among final-year students in Europe. Students had a poor knowledge of drug interactions and contraindications, and chose inappropriate therapies for common diseases or made prescribing errors. Our results suggest that undergraduate teaching in CPT is inadequate in many European schools, leading to incompetent prescribers and potentially unsafe patient care. A European core curriculum with clear learning outcomes and assessments should be urgently developed. © 2016 The Authors.

The goal of this study was to assess how often potentially inappropriate medicines are used by the elderly at home, and analyze its clinical significance. This is a retrospective cross-sectional study, a segment of a study on the use of medication conducted at a public hospital. Inappropriate medication was classified according to the three criteria in the 2012 Beers List. 190 elderly were included in this study; the prevalence of the use of inappropriate medicines was 44.2%. The therapeutic classes of most often used inappropriate medicines were non-steroid anti-inflammatories, cardiovascular agents, benzodiazepines and antidepressants. We found a positive association between the use of inappropriate medicines and polypharmacy, polypathology and hypertension. The 2013 Rename identified 35 inappropriate drugs (34.3%). The study showed a high prevalence of using inappropriate medicines by the elderly. The clinical consequences of using inappropriate medicines are important for public health due to the risk of adverse events and a negative impact on elderly functionality. When it comes to caring for the elderly, it is important to develop measures to foster the rational use of medication.

To develop a theoretically informed and empirically validated survey instrument for assessing prescribers' perception of computerized drug-drug interaction (DDI) alerts. The survey is grounded in the unified theory of acceptance and use of technology and an adapted accident causation model. Development of the instrument was also informed by a review of the extant literature on prescribers' attitude toward computerized medication safety alerts and common prescriber-provided reasons for overriding. To refine and validate the survey, we conducted a two-stage empirical validation study consisting of a pretest with a panel of domain experts followed by a field test among all eligible prescribers at our institution. The resulting survey instrument contains 28 questionnaire items assessing six theoretical dimensions: performance expectancy, effort expectancy, social influence, facilitating conditions, perceived fatigue, and perceived use behavior. Satisfactory results were obtained from the field validation; however, a few potential issues were also identified. We analyzed these issues accordingly and the results led to the final survey instrument as well as usage recommendations. High override rates of computerized medication safety alerts have been a prevalent problem. They are usually caused by, or manifested in, issues of poor end user acceptance. However, standardized research tools for assessing and understanding end users' perception are currently lacking, which inhibits knowledge accumulation and consequently forgoes improvement opportunities. The survey instrument presented in this paper may help fill this methodological gap. We developed and empirically validated a survey instrument that may be useful for future research on DDI alerts and other types of computerized medication safety alerts more generally.

In the past decade, the federal government has frequently investigated and prosecuted pharmaceutical manufacturers for illegal promotion of drugs for indications not approved by the Food and Drug Administration (FDA) ("off-label" uses). State governments can choose to coordinate with the federal investigation, or pursue their own independent state investigations. One of the largest-ever off-label prosecutions relates to the atypical antipsychotic drug olanzapine (Zyprexa). In a series of settlements between 2008 and 2010, Eli Lilly paid $1.4 billion to the federal government and over $290 million to state governments. We examined the effect of these settlements on off-label prescribing of this medication, taking advantage of geographical differences in states' involvement in the investigations and the timing of the settlements. However, we did not find a reduction in off-label prescribing; rather, there were no prescribing changes among states that joined the federal investigation, those that pursued independent state investigations, and states that pursued no investigations at all. Since the settlements of state investigations of off-label prescribing do not appear to significantly impact prescribing rates, policymakers should consider alternate ways of reducing the prevalence of non-evidence-based off-label use to complement their ongoing investigations.

Experimental and quasi-experimental studies were included that had a CASP-score>5 and that evaluated effect of any type intervention on the quality of drug prescription in Primary Health Care. A total of 522 articles were found, and an analysis was performed on 12 that reported 17 interventions: 64.7% educational, 23.5% incorporating pharmacists into the health team, and 11.8% on the use of computer applications. The strong "intervention/improvement" associations were educational interventions OR=2.47 (95% CI; 2.28 - 2.69), incorporation of pharmacists OR=3.28 (95% CI; 2.58 4.18), and use of computer applications OR=10.16 (95% CI; 8.81 -11.71). The use of interventions with computer applications showed to be more effective than educational interventions and incorporation pharmacists into the health team. Future studies are required that include economic variables such as, implementation costs, drug costs and other expenses associated with health care and treatment of diseases.

This study obtained baseline information for the design of a strategy to address irrational prescribing practices in three health centers in Kampong Thom Province, Cambodia. Indicators of rational drug use have been measured and compared with Standard Guidelines. Data were collected from patients' registers and by interviewing patients immediately after patient-prescriber and patient-dispenser encounters. Checklists and pre-designed forms were used to collect data regarding the World Health Organization drug use indicators and some additional indices. Of the 330 prescriptions analyzed, the results showed that the average number of drugs per prescription was 2.35 and that a large proportion of the prescriptions contained two or more drugs that could result in adverse drug interactions. Prescribing by generic names (99.8%) was encouraging. The exposure of patients to antibiotics (66% to 100%) was high, and injection use (2.4%) was often unnecessary. Prescribing from the Essential Drugs List (99.7%) was satisfactory. The average consultation and dispensing times were short and not sufficient for patients to get health information. All the prescribed drugs were supplied, but all were inadequately labeled. Some 55% of patients knew the correct dosage of their drugs. The availability of key essential drugs (86.6%) was below the Standard. The percentages of appropriate prescriptions for treating malaria, diarrhea and acute respiratory infection treatment were 68.3%, 3.3%, and 45%, respectively. Inappropriate prescriptions were mostly due to unsuitable dosages, incorrect drugs, and the improper duration of treatment. The results suggest a need for intervention to curb the irrational use of drugs in prescribing at the three pilot health centers. Continuing education of prescribers and healthcare providers, monitoring, supervision, public education would be beneficial.

DUE (drug usage evaluation) of ticarcillin and clavulanate potassium: determining appropriate and cost-effective therapeutic options.

1988-11-01

The initial 46 patients who were prescribed the combination drug ticarcillin disodium and clavulanate potassium in a 640-bed teaching hospital were evaluated to determine the potential usefulness of the drug in the institution. The review revealed frequent use of the drug for inappropriate indications and in situations for which less expensive antimicrobials were appropriate. The results demonstrate that an increase in costs can occur when an agent that is being considered for formulary addition--because of its cost-saving potential--is not used as expected. In order to optimally utilize the clinical or cost advantages of newer antimicrobials, a program of prescriber education, drug use controls or guidelines, and a concurrent monitoring program may be required and should be implemented at the time of initial drug use within an institution.

To examine the effect of the Tool to Reduce Inappropriate Medications (TRIM), a web tool linking an electronic health record (EHR) to a clinical decision support system, on medication communication and prescribing. Randomized clinical trial. Primary care clinics at a Veterans Affairs Medical Center. Veterans aged 65 and older prescribed seven or more medications randomized to receipt of TRIM or usual care (N = 128). TRIM extracts information on medications and chronic conditions from the EHR and contains data entry screens for information obtained from brief chart review and telephonic patient assessment. These data serve as input for automated algorithms identifying medication reconciliation discrepancies, potentially inappropriate medications (PIMs), and potentially inappropriate regimens. Clinician feedback reports summarize discrepancies and provide recommendations for deprescribing. Patient feedback reports summarize discrepancies and self-reported medication problems. Primary: subscales of the Patient Assessment of Care for Chronic Conditions (PACIC) related to shared decision-making; clinician and patient communication. Secondary: changes in medications. 29.7% of TRIM participants and 15.6% of control participants provided the highest PACIC ratings; this difference was not significant. Adjusting for covariates and clustering of patients within clinicians, TRIM was associated with significantly more-active patient communication and facilitative clinician communication and with more medication-related communication among patients and clinicians. TRIM was significantly associated with correction of medication discrepancies but had no effect on number of medications or reduction in PIMs. TRIM improved communication about medications and accuracy of documentation. Although there was no association with prescribing, the small sample size provided limited power to examine medication-related outcomes. © 2017, Copyright the Authors Journal compilation © 2017, The

To examine the impact of the Preferred Drugs Initiative (PDI), an Irish health policy aimed at enhancing evidence-based cost-effective prescribing, on prescribing trends and the cost of prescription medicines across seven medication classes. Retrospective repeated cross-sectional study spanning the years 2011 - 2016. Health Service Executive Primary Care Reimbursement Service pharmacy claims data for General Medical Services (GMS) patients, approximately 40% of the Irish population. Adults aged ≥18 years between 2011 and 2016 are eligible for the GMS scheme. The percentage of PDI medications within each drug class per calendar quarter. Linear regression was used to model prescribing of the preferred drug within each medication group and to assess the impact of PDI guidelines and other relevant changes in prescribing practice. Savings in drug expenditure were estimated. Between 2011 and 2016, around a quarter (23.59%) of all medications were for single-agent drugs licensed in the seven drug classes. There was a small increase in the percentage of PDI drugs, increasing from 4.64% of all medications in 2011 to 4.76% in 2016 (P<0.001). The percentage of preferred drugs within each drug class was significantly higher immediately following publication of the guidelines for all classes except urology, with the largest increases noted for lansoprazole (1.21%, 95% CI: 0.84% to 1.57%, P<0.001) and venlafaxine (0.71%, 95% CI: 0.15% to 1.27%, P=0.02). Trends in prescribing of the preferred drugs between PDI guidelines and the end of 2016 varied between drug classes. Total cost savings between 2013 and 2016 were estimated to be €2.7 million. There has been a small increase in prescribing of PDI drugs in response to prescribing guidelines, with inconsistent changes observed across therapeutic classes. These findings are relevant where health services are seeking to develop more active prescribing interventions aimed at changing prescribing practice. © Article author

Objective To analyse whether prescribing patterns changed after introduction of drug budgets and whether there is an association between drug prescribing patterns and the type of employer and care facility. Methods Data analysed encompassed information on dispensed medicines, by workplaces, prescribed in the Region Västra Götaland, Sweden, for the years 2003 and 2006. Workplaces (n = 969) were categorized according to type of employer and type of care facility. Five prescribing indicators reflecting goals for cost-containing prescribing in Region Västra Götaland were assessed. Changes over time and differences between different types of employer and care facility were analysed by Mann–Whitney tests. Results In 2003, workplaces with a public employer had a significantly higher adherence to three of the prescribing indicators compared with private practitioners. Two of these differences remained in 2006. In 2003, none of the prescribing indicators differed between primary care and other care facilities. Three years later workplaces in primary care had a significantly higher adherence to three of the prescribing indicators than other care facilities. There was a statistically significant difference in change between 2003 and 2006 between primary care and other care facilities; there were no differences in change between workplaces with public and private employers. Conclusions Adherence to three of the prescribing indicators increased after the introduction of decentralized drug budgets. Workplaces with a public employer showed greater adherence to two of the prescribing indicators than private sector workplaces. PMID:19291589

Concerns over rising drug costs, pharmaceutical advertising, and potential conflicts of interest have focused attention on physician prescribing behavior. We examine how broadly physicians prescribe within the 10 most prevalent therapeutic classes, the factors affecting their choices, and the impact of their prescribing behavior on patient-level outcomes. Retrospective study from 2005 to 2007 examining prescribers with at least 5 initial prescriptions within a class from 2005 to 2007. Medical and pharmacy claims are linked to prescriber information from 146 different health plans, reflecting 1975 to 8923 unique providers per drug class. Primary outcomes are the number of distinct drugs in a class initially prescribed by a physician over 1- and 3-year periods, medication possession ratio, and out-of-pocket costs. In 8 of 10 therapeutic classes, the median physician prescribes at least 3 different drugs and fewer than 1 in 6 physicians prescribe only brand drugs. Physicians prescribing only 1 or 2 drugs in a class are more likely to prescribe the most advertised drug. Physicians who prescribe fewer drugs are less likely to see patients with other comorbid conditions and varied formulary designs. Prescribing fewer drugs is associated with lower rates of medication adherence and higher out-ofpocket costs for drugs, but the effects are small and inconsistent across classes. Physicians prescribe more broadly than commonly perceived. Though narrow prescribers are more likely to prescribe highly advertised drugs, few physicians prescribe these drugs exclusively. Narrow prescribing has modest effects on medication adherence and out-of-pocket costs in some classes.

The intervention level of epidemiology is useful for studying effects in health systems research. Due to practical and ethical reasons, it is often difficult to apply experimental methods such as classical randomized clinical trials in the field. However with alternative approaches such as 'randomization by group' some of these problems can be overcome. Drug information has since long been considered as an instrument to influence physicians, however evaluation of its effects is a new field of research. In the present study the impact of drug information on prescribing behaviour was evaluated in an outpatient setting in Sri Lanka. The study included 15 state health institutions (45 prescribers) with a common drug formulary. Groups of prescribers were randomized into two interventions; newsletters and newsletters reinforced by a group seminar, and one control group. The target topic was 'rational prescribing of antibiotics'. Some 18,766 randomly selected outpatient drug prescriptions were studied. Antibiotics (and sulphonamides) were prescribed to 33.2% of the patients. An overall trend towards a decrease in proportion of patients prescribed antibiotics in the two intervention groups was seen, although the difference was not significant (p greater than 0.05) compared to the control group. This is similar to the effect of written information on prescribing in other studies. A mean difference of -7.4% in written, -7.3% in written + seminar and -0.4% in the control group was shown. The general antibiotic prescribing pattern did not change in any of the three groups. Penicillin was the most commonly prescribed antibiotic and tetracycline was only rarely prescribed to children. This experiment indicates the feasibility of drug information intervention studies in developing countries.(ABSTRACT TRUNCATED AT 250 WORDS)

The prevalence and predisposing factors were determined for inappropriate urinary catheterization (UC) among inpatients in medical wards. A cross-sectional study was conducted including all patients aged ≥ 18 years admitted to medical wards in a 1300-bed tertiary-care centre, and who had a urinary catheter in place on the day of the survey. Of 380 patients observed, 46 (12.1%) had a urinary catheter in place. Twelve of them (26.1%) were inappropriately catheterized. The most common indication for inappropriate UC was urine output monitoring in a cooperative, non-critically ill patient. Inappropriateness was associated with increased age, poor functional status, urinary incontinence, dementia, and admission from a long-term care facility. Further educational efforts should be focused on improving catheterization prescribing practices by physicians. Copyright © 2012 Elsevier España, S.L. All rights reserved.

To address the opioid overdose epidemic in the United States, states have implemented policies to reduce inappropriate opioid prescribing. These policies could affect the coincident heroin overdose epidemic by either driving the substitution of heroin for opioids or reducing simultaneous use of both substances. We used IMS Health's National Prescription Audit and government mortality data to examine the effect of these policies on opioid prescribing and on prescription opioid and heroin overdose death rates in the United States during 2006-13. The analysis revealed that combined implementation of mandated provider review of state-run prescription drug monitoring program data and pain clinic laws reduced opioid amounts prescribed by 8 percent and prescription opioid overdose death rates by 12 percent. We also observed relatively large but statistically insignificant reductions in heroin overdose death rates after implementation of these policies. This combination of policies was effective, but broader approaches to address these coincident epidemics are needed. Project HOPE—The People-to-People Health Foundation, Inc.

Recently guidelines for the treatment and prevention of ulcers induced by nonsteroidal anti-inflammatory drugs (NSAIDs) have been established. The aim of the present study was to examine factors influencing orthopedists in Japan in the use of cytoprotective drugs to prevent NSAID-associated gastrointestinal adverse events. We sent a questionnaire to 402 orthopedists in Hyogo Prefecture. A standardized 10-item questionnaire was used to collect information on NSAID prescriptions (drug name, pharmaceutical form, doses, and duration of use) and associated drugs, especially gastroprotective drugs. Two hundred eight (51.7%) orthopedists returned the questionnaire. The most frequently used NSAIDs, in descending order, were loxoprofen sodium, diclofenac sodium, and etodolac. Most doctors (80%) reported patients with abdominal symptoms associated with NSAIDs. Of these doctors, 59% treated the symptoms by themselves, and prescribed gastroprotective agents (32.2%), histamine H2-receptor antagonists (H2RAs) (26.4%), prostaglandin analogues (PAs) (17.0%), or proton pump inhibitors (PPIs) (16.2%). Sixty-seven percent of doctors reported that those drugs reduced the symptoms. Most orthopedists (96%) prescribed some type of drug to prevent NSAID-associated gastrointestinal events, including gastroprotective drugs (44.6%), H2RAs (19.5%), PAs (17.4%), and PPIs (10.8%). The doctors reported that they prescribed medicines for NSAID-associated gastrointestinal events on the basis of their experience (23%), by considering medical insurance restrictions (17%), and by referring to information provided by pharmaceutical company representatives (16%). Most orthopedists prescribe some type of drug to prevent NSAID-induced ulcers but do not refer to the guidelines. We therefore strongly recommend that the guidelines be made more widely known to gastroenterologists and to physicians in every field of clinical practice, including orthopedics.

To compare the detection of potentially inappropriate medication (PIM) using the original Beers criteria, a global reference for evaluating prescriptions in the elderly, and their Spanish version. Retrospective observational study LOCATION: A Primary Care area in the province of Murcia, Spain. A total of 7,856 subjects aged 65 and over, with at least one drug prescribed in a Primary Care Area of Spain during study period. Illnesses and treatments registered in the Primary Care computerised medical history of patients were analysed during a 12month study period (2012). The original Beers criteria and their Spanish adaptation were used to evaluate PIM, considering both sets of criteria overall, and individually. The median age of the patients was 76.0years, with the majority females (56.6%). Patients received a median of 13 active substances and 66 medical prescriptions. The percentage of patients prescribed PIM ranged from 44.8% according to the original Beers criteria to 49.4% with the Spanish adaptation. PIMs are frequent in our context. The original Beers criteria, if not adapted to the local drug catalogue, underestimated the frequency of PIM in the elderly population studied. Copyright © 2017 Elsevier España, S.L.U.

result in complex prescribing information. Genotype-specific dosing regimens will have to be more precise and marketing strategies more prudent. However, not all variations in drug responses are related to pharmacogenetic polymorphisms. Drug response can be modulated by a number of non-genetic factors, especially co-medications and presence of concurrent diseases. Inappropriate prescribing frequently compounds the complexity introduced by these two important non-genetic factors. Unless prescribers adhere to the prescribing information, much of the benefits of pharmacogenetics will be squandered. Discovering highly predictive genotype–phenotype associations during drug development and demonstrating their clinical validity and utility in well-designed prospective clinical trials will no doubt better define the role of pharmacogenetics in future clinical practice. In the meantime, prescribing should comply with the information provided while pharmacogenetic research is deservedly supported by all concerned but without unrealistic expectations. PMID:16096112

We examined patterns of antiepileptic drug (AED) use in a cohort of Iraq/Afghanistan war veterans (IAVs) who were previously identified as having epilepsy. We hypothesized that clinicians would be more likely to prescribe newer AEDs and would select specific AEDs to treat seizures based on patient characteristics including gender and comorbidities. From the cohort of IAVs previously identified with epilepsy between fiscal years 2009 and 2010, we selected those who received AEDs from the Veterans Health Administration in FY2010. Regimens were classified as monotherapy or polytherapy, and specific AED use was examine overall and by gender. Multivariable logistic regression examined associations of age; gender; race/ethnicity; medical, psychiatric, and neurological comorbidities; and receipt of neurology specialty care associated with the six most commonly used AEDs. Among 256,284 IAVs, 2123 met inclusion criteria (mean age: 33years; 89% men). Seventy-two percent (n=1526) received monotherapy, most commonly valproate (N=425) and levetiracetam (n=347). Sixty-one percent of those on monotherapy received a newer AED (levetiracetam, topiramate, lamotrigine, zonisamide, oxcarbazepine). Although fewer women than men received valproate, nearly 90% (N=45) were of reproductive age (≤45years). Antiepileptic drug prescribing patterns were associated with posttraumatic stress disorder, bipolar disorder, cerebrovascular disease, dementia/cognitive impairment, headache, and receipt of neurological specialty care (all p<0.01). In this cohort of veterans with epilepsy, most received AED monotherapy and newer AEDs. Prescribing patterns were different for men and women. The patterns observed between AEDs and neurological/psychiatric comorbidities suggest that clinicians are practicing rational prescribing. Copyright © 2015. Published by Elsevier Inc.

Evidence supports the potential for e-prescribing to reduce the incidence of adverse drug events (ADEs) in hospital-based studies, but studies in the ambulatory setting have not used occurrence of ADE as their outcome. Using the “prescription origin code” in 2011 Medicare Part D prescription drug events files, the authors investigate whether physicians who meet the meaningful use stage 2 threshold for e-prescribing (≥50% of prescriptions e-prescribed) have lower rates of ADEs among their diabetic patients. Risk of any patient with diabetes in the provider’s panel having an ADE from anti-diabetic medications was modeled adjusted for prescriber and patient panel characteristics. Physician e-prescribing to Medicare beneficiaries was associated with reduced risk of ADEs among their diabetes patients (Odds Ratio: 0.95; 95% CI, 0.94-0.96), as were several prescriber and panel characteristics. However, these physicians treated fewer patients from disadvantaged populations. PMID:25948698

Describe the impact of newer antiepileptic drugs (AEDs) on prescribing practices in a large, residential intermediate-care facility for the mentally retarded (ICF-MR), with onsite clinical pharmacist support services, over a 15-year period. All residents at the facility receiving AEDs for management of seizure disorder were included in this retrospective assessment. Number and type of AEDs used per individual were recorded and analyzed over the 15-year interval. Current prescribing practices were evaluated regarding rational polytherapy prescribing trends. 400-bed residential ICF-MR for the severe to profoundly mentally retarded. All individuals residing at the ICF-MR facility receiving AED therapy for a seizure disorder. Residents were primarily in the severe to profound range of developmental disability, with multiple medical comorbidities. Clinical pharmacists actively participate in all treatment teams and monthly neurology clinic to promote and encourage rational pharmacotherapy. Prescribing trends related to AED therapy were followed over a 15-year period. Comparisons were made regarding monotherapy and polytherapy at multiple-year intervals, with specific emphasis on how the newer generation AEDs have affected use of older medications. Overall trend from 1988 suggests more monotherapy and less use of barbiturates. Introduction of a new generation of AEDs has not affected the overall trend toward one- or two-drug regimens over the period in review. The relative stability of the number of AEDs per resident during the introduction of a new generation of AEDs suggests that as new drugs are added, ineffective or problem-prone drugs are discontinued.

The purpose of this study was to determine the effects of a new drug-pricing system (January 2012) and new prescription and reimbursement guidelines (January 2013) on hypertension-related pharmaceutical expenditures and prescribing behaviors in Korea. In all, 11,298 clinics and 2,667,132 patients with hypertension were included in our study. As dependent variables, we used the drug cost per patient, drug cost per prescribed day, number of drugs per prescription, number of prescribed days per visit, number of visits, number of original (vs. generic) drugs prescribed, and the percentage of original drug cost. Clinic characteristics and patients' age and sex were used as independent variables. Multi-level mixed-effect regression models were used. The drug cost per patient decreased by -1446 KRW$ (-7.4%; p<0.001) in Q4 2012 and by -1833 (-9.3%; p<0.001) in Q2 2013 compared with Q4 2011. Number of drugs per prescription decreased significantly. The percentage of original drug cost and the number of original drugs also declined. Reforms to the drug pricing policy and the new guidelines may reduce pharmaceutical expenditures without increasing number of drugs per prescription and the number of original drug used. Policy makers should consider the comprehensive effects of implementing new policies on both drug prices and consumption. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Aims This study aims to determine if potentially inappropriate prescribing (PIP) is associated with increased healthcare utilization, functional decline and reduced quality of life (QoL) in a community‐dwelling older cohort. Method This prospective cohort study included participants aged ≥65 years from The Irish Longitudinal Study on Ageing (TILDA) with linked administrative pharmacy claims data who were followed up after 2 years. PIP was defined by the Screening Tool for Older Persons Prescriptions (STOPP) and Screening Tool to Alert doctors to Right Treatment (START). The association with number of emergency department (ED) visits and GP visits reported over 12 months was analyzed using multivariate negative binomial regression adjusting for confounders. Marginal structural models investigated the presence of time‐dependent confounding. Results Of participants followed up (n = 1753), PIP was detected in 57% by STOPP and 41.8% by START, 21.7% reported an ED visit and 96.1% visited a GP (median 4, IQR 2.5–6). Those with any STOPP criterion had higher rates of ED visits (adjusted incident rate ratio (IRR) 1.30, 95% confidence interval (CI) 1.02, 1.66) and GP visits (IRR 1.15, 95%CI 1.06, 1.24). Patients with two or more START criteria had significantly more ED visits (IRR 1.45, 95%CI 1.03, 2.04) and GP visits (IRR 1.13, 95%CI 1.01, 1.27) than people with no criteria. Adjusting for time‐dependent confounding did not affect the findings. Conclusions Both STOPP and START were independently associated with increased healthcare utilization and START was also related to functional decline and QoL. Optimizing prescribing to reduce PIP may provide an improvement in patient outcomes. PMID:27136457

While self-medication is common, inappropriate self-medication has potential risks. This study assesses inappropriate self-medication among adolescents and examines the relationships among medication literacy, substance use, and inappropriate self-medication. In 2016, a national representative sample of 6,226 students from 99 primary, middle, and high schools completed an online self-administered questionnaire. Multiple logistic regression analysis was used to examine factors related to inappropriate self-medication. The prevalence of self-medication in the past year among the adolescents surveyed was 45.8%, and the most frequently reported drugs for self-medication included nonsteroidal anti-inflammatory drugs or pain relievers (prevalence = 31.1%), cold or cough medicines (prevalence = 21.6%), analgesics (prevalence = 19.3%), and antacids (prevalence = 17.3%). Of the participants who practiced self-medication, the prevalence of inappropriate self-medication behaviors included not reading drug labels or instructions (10.1%), using excessive dosages (21.6%), and using prescription and nonprescription medicine simultaneously without advice from a health provider (polypharmacy) (30.3%). The results of multiple logistic regression analysis showed that after controlling for school level, gender, and chronic diseases, the participants with lower medication knowledge, lower self-efficacy, lower medication literacy, and who consumed tobacco or alcohol were more likely to engage in inappropriate self-medication. Lower medication literacy and substance use were associated with inappropriate self-medication among adolescents.

Physical restraints in home care and residential care settings in the form of restraining devices have been reduced in the last years. Now psychotropic drugs with sedating and thus potentially restraining effect are of increasing interest. The objective of this study was to describe prescription of psychotropic drugs for insurants in need of care and factors influencing such prescription. On the "Annual Word Elder Abuse Awareness Day", the Medical Service of the Statutory Health Insurance undertook a reference day analysis. During the regular assessment of care needs, distribution of psychotropic drugs according to relevant aspects of care were analyzed. Additionally, prescribed drugs were rated with respect to inappropriateness for elder people according to the Priscus list. Data on 706 insured people were analyzed; 43% of them received at least one psychotropic drug as a regular medication, 22% of them at least one potentially sedating drug. According to the Priscus list, 16% of prescribed drugs were identified as potentially inappropriate for elder people. Significant correlation was shown between prescription of psychotropic drugs and location of assessment, care need, diagnosis and the degree of limitation in daily living skills. This paper supports results in literature and emphasizes the discrepancy between restraint in the prescription of psychotropic drugs as advised by experts and distribution of these drugs in reality. Further studies analyzing the quality of prescriptions taking into consideration the individual circumstances of patients are desirable. © Georg Thieme Verlag KG Stuttgart · New York.

Due to the high rates of inappropriate antibiotic prescribing for presumed urinary tract infections (UTIs) in nursing home (NH) residents, we sought to examine the antibiotic prescribing pathway and the extent to which it agrees with the Loeb criteria; findings can suggest strategies for antibiotic stewardship. Chart review of 260 randomly-selected cases from 247 NH residents treated with an antibiotic for a presumed UTI in 31 NHs in North Carolina. We examined the prescribing pathway from presenting illness, to the prescribing event, illness work-up and subsequent clinical events including emergency department use, hospitalization, and death. Analyses described the decision-making processes and outcomes and compared decisions made with Loeb criteria for initiation of antibiotics. Of 260 cases, 60% had documented signs/symptoms of the presenting illness and 15% met the Loeb criteria. Acute mental status change was the most commonly documented sign/symptom (24%). NH providers (81%) were the most common prescribers and ciprofloxacin (32%) was the most commonly prescribed antibiotic. Fourteen percent of presumed UTI cases included a white blood cell count, 71% included a urinalysis, and 72% had a urine culture. Seventy-five percent of cultures grew at least one organism with ≥100,000 colony-forming units/milliliter and 12% grew multi-drug resistant organisms; 28% of antibiotics were prescribed for more than 7 days, and 7% of cases had a subsequent death, emergency department visit, or hospitalization within 7 days. Non-specific signs/symptoms appeared to influence prescribing more often than urinary tract-specific signs/symptoms. Prescribers rarely stopped antibiotics, and a minority prescribed for overly long periods. Providers may need additional support to guide the decision-making process to reduce antibiotic overuse and antibiotic resistance. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Inappropriate antimicrobial prescribing leads to antimicrobial resistance and suboptimal clinical outcomes. Changing antimicrobial prescribing is a complex behavioral process that is not often taken into account in antimicrobial stewardship programs. To examine whether an antimicrobial stewardship approach grounded in behavioral theory and focusing on preserving prescriber autonomy and participation is effective in improving appropriateness of antimicrobial prescribing in hospitals. The Dutch Unique Method for Antimicrobial Stewardship (DUMAS) study was a prospective, stepped-wedge, participatory intervention study performed from October 1, 2011, through December 31, 2015. Outcomes were measured during a baseline period of 16 months and an intervention period of 12 months. The study was performed at 7 clinical departments (2 medical, 3 surgical, and 2 pediatric) in a tertiary care medical center and a general teaching hospital in the Netherlands. Physicians prescribing systemic antimicrobial drugs for any indication for patients admitted to the participating departments during the study period were included in the study. We offered prescribers a free choice of how to improve their antimicrobial prescribing. Prescribers were stimulated to choose interventions with higher potential for success based on a root cause analysis of inappropriate prescribing. Appropriateness of antimicrobial prescriptions was determined using a validated approach based on guideline adherence and motivated guideline deviation and measured with repeated point prevalence surveys (6 per year). Appropriateness judgment was masked for the study period. Antimicrobial consumption was extracted from pharmacy records and measured as days of therapy per admission. We used linear and logistic mixed-model regression analysis to model outcomes over time. A total of 1121 patient cases with 700 antimicrobial prescriptions were assessed during the baseline period and 882 patient cases with 531

Electronic prescribing (e-prescribing) provides formulary information at the point of care. The objective of this study was to assess the effects of e-prescribing on formulary compliance and generic utilization. This was a retrospective analysis of pharmacy claims data from a large national managed care organization. A sample of 95 providers using predominantly e-prescribing was randomly selected (e-prescriber group). A matched sample of 95 traditional prescribers was selected (traditional prescriber group), matched to the e-prescriber group by zip code and medical specialty. A total of 110,975 paid pharmacy claims, for the 12 months from August 1, 2001, through July 31, 2002, were analyzed to assess the effect of e-prescribing on formulary compliance and generic utilization. All paid pharmacy claims were examined for each group; for the e-prescriber group, this included all claims, not just those prescribed using an e-prescribing device. A written qualitative survey was distributed to physicians and office managers to assess e-prescribing usage, sources of formulary information, and effects of e-prescribing on office resources. Both predominantly e-prescribers and traditional prescribers demonstrated high levels of formulary compliance, 83.2% versus 82.8%, respectively (P=0.32). Formulary compliance for these groups did not differ from the overall prescriber population (82.0%). There was not a difference in generic drug utilization rates between e-prescribers and traditional prescribers (absolute rates 37.3% versus 36.9%, P=0.18). Qualitative survey responses supported previously reported research indicating reductions in calls both to and from pharmacies for prescription orders. An examination of paid pharmacy claims from a large, national managed care organization demonstrated no differences between predominantly e-prescribers and traditional prescribers in measures of formulary compliance or generic drug utilization. Future studies should examine keystroke data

Pre-exposure prophylaxis for HIV (PrEP) is recommended for people who inject drugs (PWID). Despite their central role in disease prevention, willingness to prescribe PrEP to PWID among primary care physicians (PCPs) is largely understudied. We conducted an online survey (April-May 2015) of members of a society for academic general internists regarding PrEP. Among 250 respondents, 74% (n = 185) of PCPs reported high willingness to prescribe PrEP to PWID. PCPs were more likely to report high willingness to prescribe PrEP to all other HIV risk groups (p's < 0.03 for all pair comparisons). Compared with PCPs delivering care to more HIV-infected clinic patients, PCPs delivering care to fewer HIV-infected patients were more likely to report low willingness to prescribe PrEP to PWID (Odds Ratio [95% CI] = 6.38 [1.48-27.47]). PCP and practice characteristics were not otherwise associated with low willingness to prescribe PrEP to PWID. Interventions to improve PCPs' willingness to prescribe PrEP to PWID are needed.

Background Inappropriate use of antibiotics is a global public health challenge and has been associated with antibiotic resistance. WHO reports show that efforts to promote rational antibiotic use in developing countries are poor. With the growing number of infections with antibiotic resistant bacteria, rational drug use becomes imperative and studies that promote rational drug use are highly necessary. Considering this, we investigated prescribing patterns and predictors of antibiotic prescription in primary health care facilities in Kumbo East (KE) and Kumbo West (KW) health districts in North West Cameroon, to contribute data which could influence policy on antibiotic use. Methods and findings A cross sectional retrospective study was conducted from April 2014 to April 2015 in 26 randomly selected primary care facilities. Questionnaires were administered to 59 antibiotic prescribers to determine factors that predict antibiotic prescribing. Data on antibiotic prescription were collected by review of consultation registers. Prescription rates and demographics, prescriber and institution factors were analyzed using ANOVA. The best predictor of prescription was determined using multiple linear regression analysis. Results A total of 30,096 prescriptions were reviewed. Overall antibiotic prescription rate was 36.71%, with a mean of 1.14 antibiotics prescribed per patient. Amoxicillin was the most prescribed (29.9%). The most prevalent indications for prescribing were respiratory tract infections (21.27%). All antibiotics prescribed were broad-spectrum. Antibiotics were prescribed for patients with malaria and also in situations where diagnosis was uncertain. Prescribing by generic name was 98.36% while 99.87% was from Essential Drug List. Use of laboratory results, patient turnout and Performance Based Financing (PBF) were significantly associated with antibiotic prescribing rates (p < 0.05). PBF moderated prescribing. Conclusion There was misuse of antibiotics in

To determine the extent to which the strictness of the criteria used to control utilization of drugs not on a Medicaid preferred drug list (PDL) changes physician prescribing habits for non-Medicaid patients. Quasi-experimental design based on different timing of states' enactment of PDLs for cardiovascular medications. A regression model was developed to analyze the effect that PDL implementation had on off-PDL product market share across 3 patient types (Medicaid, third-party insurance, and cash paying). The models included data from 2 states (Illinois and Louisiana) with different PDL prior-authorization criteria. The data allowed examination of different physician responses according to the proportion of Medicaid patients treated by the physician. The analysis also followed prescribing patterns longitudinally to determine whether the PDL-induced prescribing behaviors changed over time. There was a decrease of 9 percentage points (67.7%) and 6.2 percentage points (40.5%) in the Medicaid prescription share of restricted cardiovascular drugs post-PDL for Illinois and Louisiana, respectively. In the third-party insurance market, prescription shares of off-PDL drugs decreased 0.9 percentage points (6.8%) in Illinois and 1.3 percentage points (8.6%) in Louisiana. For physicians with a high percentage of prescriptions paid for by Medicaid, the share loss for off-PDL drugs was estimated to be more than 37% for the non-Medicaid portion of the practice. The effects of a Medicaid PDL on prescribing behavior extend beyond the Medicaid population. The health outcomes and economic consequences of these "spillover" effects are poorly understood and warrant further research.

Literature has shown dentists tend to overprescribe antibiotics and do not always prescribe in accordance with recommended guidelines. Unnecessary prescribing is one major factor that contributes to the development of antibiotic resistance. The aim of the present study was to assess the antibacterial prescribing patterns of dentists in Australia from 2013 to 2016. Data on dental antibacterial prescriptions dispensed under the Pharmaceutical Benefits Scheme (PBS) from 2013 to 2016 was accessed and prescribing trends analysed. The prescribing rates were standardised to the dose and population. There was a slight decrease in the dispensed use of most antibacterials from 2013-16, but there was a significant increase in the dispensed use of amoxicillin/clavulanic acid of 11.2%. Amoxicillin was the most commonly dispensed antibiotic, accounting for around 65% of all antibacterials from 2013-16, while phenoxymethylpenicillin accounted for only 1.4% of prescriptions in 2016. There were low but significant quantities of dispensed antibiotic prescriptions that do not fit with current guidelines. The data suggest that dentists in Australia are prescribing some antibiotics inappropriately and there is a preference for moderate to broad spectrum agents. The current PBS dental schedule is inconsistent with prescribing guidelines and may contribute to inappropriate prescribing. This article is protected by copyright. All rights reserved.

Purpose. By examining the prescribing patterns and inappropriate use of acid suppressive therapy (AST) during hospitalization and at discharge we sought to identify the risk factors associated with such practices. Methods. In this retrospective observational study, inpatient records were reviewed from January 2011 to December 2013. Treatment with AST was considered appropriate if the patient had a known specific indication or met criteria for stress ulcer prophylaxis. Results. In 2011, out of 58 patients who were on AST on admission, 32 were newly started on it and 23 (72%) were inappropriate cases. In 2012, out of 97 patients on AST, 61 were newly started on it and 51 (84%) were inappropriate cases. In 2013, 99 patients were on AST, of which 48 were newly started on it and 36 (75%) were inappropriate cases. 19% of the patients inappropriately started on AST were discharged on it in three years. Younger age, female sex, and 1 or more handoffs between services were significantly associated with increased risk of inappropriate AST. Conclusion. Our findings reflect inappropriate prescription of AST which leads to increase in costs of care and unnecessarily puts the patient at risk for potential adverse events. The results of this study emphasize the importance of examining the patient's need for AST at each level of care especially when the identified risk factors are present. PMID:27818680

Drug reimbursement and GPs' prescribing decisions: a randomized case-vignette study about the pharmacotherapy of obesity associated with type 2 diabetes: how GPs react to drug reimbursement.

This study sought to identify the effect of drug reimbursability--a decision made in France by the National Authority for Health--on physicians' prescribing practices for a diet drug such as rimonabant, approved for obese or overweight patients with type-2 diabetes. A cross-sectional survey of French general practitioners (GPs) presented a case-vignette about a patient for whom this drug is indicated in two alternative versions, differing only in its reimbursability, to two separate randomized subsamples of GPs in early 2007, before any decision was made about reimbursement. The results indicate that (i) more than 20% of GPs in private practice would be willing to prescribe a non-reimbursed diet drug for patients with obesity complicated by type 2 diabetes; (ii) the number of GPs willing to prescribe it would increase by 47.6% if the drug were reimbursed, and (iii) such a drug would be adopted at a higher rate by GPs who have regular contacts with pharmaceutical sales representatives. In France, unlike most other countries, drug reimbursement status is a signal of quality. However, our results suggest that a significant proportion of GPs would spontaneously adopt anti-obesity drugs even if they were not reimbursed. Decisions about reimbursement of pharmaceutical products should be made taking into account that reimbursement is likely to intensify prescription.

Concern about the potential pernicious effect of direct-to-consumer (DTC) drug advertising on physicians' prescribing patterns was heightened with the 2004 withdrawal of Vioxx, a heavily advertised treatment for osteoarthritis. We examine how DTC advertising has affected physicians' prescribing behavior for osteoarthritis patients. We analyzed monthly clinical information on fifty-seven primary care practices during 2000-2002, matched to monthly brand-specific advertising data for local and network television. DTC advertising of Vioxx and Celebrex increased the number of osteoarthritis patients seen by physicians each month. DTC advertising of Vioxx increased the likelihood that patients received both Vioxx and Celebrex, but Celebrex ads only affected Vioxx use.

AIMS The international childhood obesity epidemic has driven increased use of unlicensed antiobesity drugs, whose efficacy and safety are poorly studied in children and adolescents. We investigated the use of unlicensed antiobesity drugs (orlistat, sibutramine and rimonabant) in children and adolescents (0–18 years) in the UK. METHODS Population-based prescribing data from the UK General Practice Research Database between 1 January 1999 and 31 December 2006. RESULTS A total of 452 subjects received 1334 prescriptions during the study period. The annual prevalence of antiobesity drug prescriptions rose significantly from 0.006 per 1000 [95% confidence interval (CI) 0.0007, 0.0113] in 1999 to 0.091 per 1000 (95% CI 0.07, 0.11) in 2006, a 15-fold increase, with similar increases seen in both genders. The majority of prescriptions were made to those ≥14 years old, although 25 prescriptions were made for children <12 years old. Orlistat accounted for 78.4% of all prescriptions; only one patient was prescribed rimonabant. However, approximately 45% of the patients ceased orlistat and 25% ceased sibutramine after only 1 month. The estimated mean treatment durations for orlistat and sibutramine were 3 and 4 months, respectively. CONCLUSIONS Prescribing of unlicensed antiobesity drugs in children and adolescents has dramatically increased in the past 8 years. The majority are rapidly discontinued before patients can see weight benefit, suggesting they are poorly tolerated or poorly efficacious when used in the general population. Further research into the effectiveness and safety of antiobesity drugs in clinical populations of children and adolescents is needed. PMID:20002078

Increased prescribing of Valium, Librium, and other drugs--an example of the influence of economic and social factors on the practice of medicine.

Drug prescriptions per capita in the United States have more than doubled since 1950 without a commensurate improvement in health. Drugs are often prescribed for clinical conditions in which therapeutic benefits do not outweigh the risk of adverse drug reactions. Deaths due to adverse drug reactions are roughly as frequent as deaths due to automobile accidents. Valium and Librium are the first and fourth most commonly prescribed drugs in the U.S., used by one ten adults each year. The rapid rise in use of these drugs has occurred during a period of rising social stress, as indicated by increases in alcohol consumption, suicide, and homicide, Valium and Librium are frequently prescribe for patients who go to doctors with social or other nonmedical problems, often in lieu of attempts to resolve these underlying problems. Overprescribing occurs because the decision to prescribe is influenced not only by consideration of therapeutic benefit, but also by nonmedical factors, for example the widespread expectation by both patient and doctor that the doctor will provide a drug or some other technological treatment. Prescribing decisions are also influenced by the profit-motivated activities of drug companies, including the expenditure of almost one-quarter of every sales dollar on drug promotion. The most widely used source of drug information for doctors is the industry-sponsored Physicians' Desk Reference, which overrates the therapeutic value of Valium and Librium as compared to disinterested medical sources. Drug companies also contribute to overprescribing by introducing numerous minor variants of existing drugs. The therapeutic benefits of such new drugs are often overestimated in the early years of use when adverse side effects are not well known and apparent efficacy is enhanced by placebo effects in uncontrolled observations.

Following a TV documentary in 2013, there was a tremendous increase in low dose naltrexone (LDN) use in a wide range of unapproved indications in Norway. We aim to describe the extent of this sudden and unprecedented increase in LDN prescribing, to characterize patients and LDN prescribers, and to estimate LDN dose sizes. LDN prescriptions recorded in the Norwegian Prescription Database (NorPD) in 2013 and 2014, and sales data not recorded in NorPD from the only Norwegian LDN manufacturer were included in the study. According to NorPD, 15 297 patients (0.3% of population) collected at least one LDN prescription. The actual number of users was higher as at least 23% of total sales were not recorded in NorPD. After an initial wave, there was a steady stream of new and persistent users throughout the study period. Median patient age was 52 years, and 74% of patients were female. Median daily dose was 3.7 mg. Twenty percent of all doctors and 71% of general medicine practitioners registered in Norway in 2014 prescribed LDN at least once. The TV documentary on LDN in Norway was followed by a large increase in LDN prescribing, and the proportion of LDN users went from an insignificant number to 0.3% of the population. There was a high willingness to use and prescribe off label despite limited evidence. Observed median LDN dose, and age and gender distribution were as expected in typical LDN using patients. © 2016 The Authors.

Prescribed drug use for bipolar disorder type I and II in clinical practice Practice guidelines based on available evidence and clinical consensus are available for the treatment of bipolar disorder. We surveyed to which extent those guidelines are implemented in clinical practice in Sweden. We analysed pharmacological treatment in patients with bipolar disorder in 2015 using the national quality register for bipolar disorder (BipoläR). We compared bipolar disorder type I (BDI) with type bipolar disorder type II (BDII). The vast majority of patients were prescribed a mood stabilizer either as monotherapy or as a part of combination therapy (BDI 87%, BDII 83%, p<0.001). Whereas lithium was the most common mood stabilizer in type I (BDI 65%, BDII 40%, p<0.001), lamotrigine was the most common mood stabilizer in type II (BDI 18%, BDII 42%, p<0.001). Antidepressants were less common in BDI than BDII (35% vs. 53%, p<0.001). Antipsychotic drugs (first or second generation) were more frequently used in BDI than BDII (49% vs 35%, p<0.001). Central stimulants were rarely used (BDI 3.1%, BDII 6.6%, p<0.001). Combining a mood stabilizer with an antipsychotic drug was more common in BDI than BDII (27% vs. 12%, p<0.001), whereas combining a mood stabilizer with an antidepressant was less common in BDI than BDII (16% vs 28%, p<0.001). We conclude that most patients are prescribed mood stabilizers and that the differences between BDI and BDII are rational given the differences in clinical manifestations. The use of antidepressants is surprisingly high given the long-standing debate about the risk and effectiveness of this class in bipolar disorder.

Inappropriate prescribing is linked to increased risks for adverse drug reactions and hospitalisation. Combining explicit and implicit criteria of inappropriate prescribing with the information obtained in patient interviews seems beneficial with regard to the identification of drug-related problems (DRPs) in hospitalised patients. We aimed to investigate the inclusion of pharmacist interviews as part of medication reviews (including the use of explicit and implicit criteria of inappropriate prescribing) to identify DRPs in older inpatients. Clinical medication reviews were performed on geriatric and associated physical and neurological rehabilitation wards in a regional secondary care hospital. Data from electronic medical records, laboratory data, and current treatment regimens were complemented with a novel structured patient interview performed by a clinical pharmacist. The structured interview questioned patients on administration issues, prescribed medication, self-medication, and allergies. The reviews included the use of current treatment guidelines, the Medication Appropriateness Index, the Screening Tool of Older People's Prescriptions (STOPP, v2), and the Screening Tool to Alert to Right Treatment (START, v2). The potential relevance of the DRPs was estimated using the German version of the CLEO tool. In 110 patients, 595 DRPs were identified, averaging 5.4 per patient (range 0-17). The structured interviews identified 249 DRPs (41.8%), of which 227 were not identified by any other source of information. The majority of DRPs (213/249, i.e. 85.5%) identified by patient interview were estimated to be of minor clinical relevance (i.e. limited adherence, knowledge, quality of life, or satisfaction). We demonstrated that structured patient interviews identified additional DRPs that other sources did not identify. Embedded within a comprehensive approach, the structured patient interviews were needed as data resource for over one-third of all DRPs.

Background: Women have higher morning serum zolpidem concentrations than men after taking an evening dose, potentially leading to increased risk of harm. On 19 April 2013, the United States Food and Drug Administration required labeling changes for zolpidem, recommending an initial dose of no greater than 5 mg (immediate release) or 6.25 mg (controlled release) per night in women. Objectives: The primary objective of this study was to compare prescribing practices before and after the 2013 zolpidem labeling change. A secondary objective was to evaluate serious adverse events potentially related to zolpidem. Methods: Electronic medical records of adults receiving care through the University of Colorado Health system were accessed for study inclusion if patients were provided a first-time prescription for zolpidem either prior to or after the Food and Drug Administration labeling change. Patients were randomly chosen from eight strata based on age, gender, and date of zolpidem initiation (before/after the labeling change). Demographic and zolpidem prescribing data were collected. Low-dose zolpidem was considered 5 mg (immediate release) or 6.25 mg (controlled release) daily or less. Documentation of potentially related serious adverse events within the patients’ records was also evaluated. Results: A total of 400 patients were included in the study. The overall percentage of patients prescribed low-dose zolpidem increased from 44% to 58% after the labeling change (p = 0.0020). In a pre-specified subgroup analysis, the percentage of patients prescribed low-dose zolpidem increased in all groups, including young men (38%–50%, p = 0.23), elderly men (34%–40%, p = 0.53), and elderly women (60%–74%, p = 0.14), but the change was only significant in young women (42%–70%, p = 0.0045). Conclusion: After Food and Drug Administration–mandated labeling changes for zolpidem in 2013, the percentage of overall patients in our health system

The aim of this study was to explore antiepileptic drug (AED) prescribing before, during and after pregnancy as recorded in seven population-based electronic healthcare databases. Databases in Denmark, Norway, the Netherlands, Italy (Emilia Romagna/Tuscany), Wales and the Clinical Practice Research Datalink, representing the rest of the UK, were accessed for the study. Women with a pregnancy starting and ending between 2004 and 2010, which ended in a delivery, were identified. AED prescriptions issued (UK) or dispensed (non-UK) at any time during pregnancy and the 6 months before and after pregnancy were identified in each of the databases. AED prescribing patterns were analysed, and the choice of AEDs and co-prescribing of folic acid were evaluated. In total, 978 957 women with 1 248 713 deliveries were identified. In all regions, AED prescribing declined during pregnancy and was lowest during the third trimester, before returning to pre-pregnancy levels by 6 months following delivery. For all deliveries, the prevalence of AED prescribing during pregnancy was 51 per 10 000 pregnancies (CI95 49-52%) and was lowest in the Netherlands (43/10 000; CI95 33-54%) and highest in Wales (60/10 000; CI95 54-66%). In Denmark, Norway and the two UK databases lamotrigine was the most commonly prescribed AED; whereas in the Italian and Dutch databases, carbamazepine, valproate and phenobarbital were most frequently prescribed. Few women prescribed with AEDs in the 3 months before pregnancy were co-prescribed with high-dose folic acid: ranging from 1.0% (CI95 0.3-1.8%) in Emilia Romagna to 33.5% (CI95 28.7-38.4%) in Wales. The country's differences in prescribing patterns may suggest different use, knowledge or interpretation of the scientific evidence base. The low co-prescribing of folic acid indicates that more needs to be done to better inform clinicians and women of childbearing age taking AEDs about the need to offer and receive complete preconception care

Pharmaceutical residues in the drinking water supply: modeling residue concentrations in surface waters of drugs prescribed in the United States.

Pharmaceutical residues and other organic wastewater contaminants (OWC) have been shown to survive conventional water-treatment processes and persist in potable water supplies. To estimate the geographical distribution of the Predicted Environmental Concentration (PEC) of selected drugs prescribed by office based physicians in the United States (US), after non-metabolized residues have been excreted and processed in wastewater treatment plants. The geographical distribution of the PEC in surface waters of pharmaceutical residues was calculated, in four regions of the US. Prescription drug data was obtained from the National Ambulatory Medical Care Survey (NAMCS). The PEC of three drugs prescribed by office based physicians in the US between 1998 and 2000 was compared to the concentrations of these pharmaceuticals found in a surface water characterization project conducted by the United States Geological Survey between 1999 and 2000. There were 803,185,420 medications prescribed by office-based physicians in the US between 1998 and 2000. Relief of pain, hormonal, cardiovascular and antimicrobial medications followed very similar prescription patterns, both in terms of quantity and geographical distribution. Together these four types of medications account for more than half of the medications prescribed between 1998 and 2000. The concentration of pharmaceutical residues found in the drinking water supply was not significantly correlated to the PEC of pharmaceuticals prescribed by office-based physicians. The geographical distribution of medications prescribed by office based physicians in the US underlines the need to implement effective public health strategies.

We reported previously the results of a 6-month controlled trial in which the use of a commercially available electronic prescribing system with integrated clinical decision support and evidence-based message capability was associated with significantly lower primary care drug costs. The original study focused on new prescriptions, defined as claims for a medication that the patient had not received in the previous 12 months. The main objectives of this follow-up report were to (a) determine if the 6-month savings on new prescriptions were sustained during 12 months of follow-up, (b) evaluate the impact of the computerized decision support system (CDSS) on all pharmacy claims and per-member-per-month (PMPM) expenditures, and (c) evaluate the prescribing behaviors within 8 high-cost therapeutic categories that were frequently targeted by the electronic messages to prescribers to help verify that the drug cost savings were due to the recommendations in the electronic prescribing system. Two database queries were performed to identify additional pharmacy claims data for all Network Health Plan patients who were cared for by the 38 primary care clinicians (32 physicians, 4 nurse practitioners, and 2 physician assistants) included in our original 6-month study. This follow-up analysis (a) identified all new prescription claims for the 2 groups of clinicians throughout the 12-month follow-up period (June 2002 through May 2003) and (b) assessed all pharmacy claims during the same 12-month period to provide more complete savings estimates and to examine between-group differences in PMPM expenditures. During 12 months of follow-up, clinicians using the electronic prescribing system continued to have lower prescription costs than the controls. Clinicians using the electronic prescribing system had average costs for 26,674 new prescriptions that were dollar 4.12 lower (95% confidence interval, dollar 1.53-dollar 6.71; P=0.003) and PMPM expenditures that were dollar 0.57 lower

Audits of antibiotic prescribing in a Bristol hospital.

1983-01-01

Audits of antibiotic prescribing were done for periods of up to eight weeks in two successive years on medical, surgical, orthopaedic, gynaecology, obstetric, and urology wards and in an accident and emergency department. Clinical details were matched with antibiotic prescribing, and the appropriateness of the latter was judged independently by two medical microbiologists. Only when they agreed was an individual prescription included in the analysis. Overall, 28% of prescriptions in 1979 and 35% in 1980 were judged as unnecessary, with 17% and 16%, respectively, being for inappropriate choices of antibiotic. An educational programme about antibiotic prescribing carried out between the audits had no beneficial effect overall. Though the results compared favourably with those of audits published, prescribing could still be much improved. To judge by the failure of education, however, this might be difficult to achieve. Most prescriptions were written by junior staff, who in the absence of guidance from their seniors and because of their frequent moves would require a widespread and continual education programme. Published concern about the quality of antibiotic prescribing appears to be justified. PMID:6401484

Insight into factors that influence antibiotic prescribing is crucial when developing interventions aimed at a more rational use of antibiotics. We examined factors that influence antibiotic prescribing in long-term care facilities, and present a conceptual model that integrates these factors. Semi-structured qualitative interviews were conducted with physicians (n = 13) and nursing staff (n = 13) in five nursing homes and two residential care homes in the central-west region of the Netherlands. An iterative analysis was applied to interviews with physicians to identify and categorize factors that influence antibiotic prescribing, and to integrate these into a conceptual model. This conceptual model was triangulated with the perspectives of nursing staff. The analysis resulted in the identification of six categories of factors that can influence the antibiotic prescribing decision: the clinical situation, advance care plans, utilization of diagnostic resources, physicians' perceived risks, influence of others, and influence of the environment. Each category comprises several factors that may influence the decision to prescribe or not prescribe antibiotics directly (e.g. pressure of patients' family leading to antibiotic prescribing) or indirectly via influence on other factors (e.g. unfamiliarity with patients resulting in a higher physician perceived risk of non-treatment, in turn resulting in a higher tendency to prescribe antibiotics). Our interview study shows that several non-rational factors may affect antibiotic prescribing decision making in long-term care facilities, suggesting opportunities to reduce inappropriate antibiotic use. We developed a conceptual model that integrates the identified categories of influencing factors and shows the relationships between those categories. This model may be used as a practical tool in long-term care facilities to identify local factors potentially leading to inappropriate prescribing, and to subsequently

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) are widely used but they increase the risk of gastrointestinal haemorrage among other adverse effects. The objective of this study was to compare potentially inappropriate medications (PIM) by NSAIDs using the original Beers Criteria, a global reference for evaluating elderly people's prescriptions, and the Spanish adaptation of the same; and the relation between PIM of NSAIDs and gastrointestinal bleeding. The study was a retrospective observational study carried out located in a primary care district in the province of de Murcia, south-eastern Spain. The study population (n=7.856) were citizens aged 65 and above, with at least one drug prescribed in a Spanish health district during the study period . We analized illnesses and treatments registered in the primary care's electronic medical history of patients and hospital admissions, during the 12 month study period (2012). The original Beers Criteria and their Spanish adaptation were used to evaluate PIM of NSAIDs in patients considering the medication globally and also each active substance. Gastrointestinal bleeding events recorded in the data bases studied were evaluated. Detection of PIM of NSAIDs was 5,6% with the original version and 7,0% (Δ=25,5%; p less than 0,001) with the adapted one. PIM of NSAIDs was related with an increased incidence of gastrointestinal bleeding without significant differences between PIM exposed and NSAID exposed patients AINE (RR=1,6; IC:0,2-14,5). The Spanish adaptation of the Beers criteria identified a greater degree of PIM of NSAIDs than the original version, and in both versions the detection of PIM was not related with a significant increase of gastrointestinal bleeding compared to patients exposed to NSAIDs.

Initiatives to improve prescribing efficiency for drugs to treat Parkinson's disease in Croatia: influence and future directions.

Parkinson's disease (PD) is the second most common neurological disease affecting older adults. Consequently, this disease should be a focus among payers, with increasing utilization of newer premium-priced patent-protected add-on therapies to stabilize or even improve motor function over time. However, expenditure can be moderated by reforms. Consequently, there is a need to assess the influence of these reforms on the prescribing efficiency for drugs to treat PD in Croatia before proposing additional measures. Prescribing efficiency is defined as increasing the use of add-on therapies for similar expenditure. An observational retrospective study of the Croatian Institute for Health Insurance database of drugs to treat patients with PD in Croatia from 2000 to 2010 was carried out, with utilization measured in defined daily doses (defined as the average maintenance dose of a drug when used in its major indication in adults). The study years were chosen to reflect recent reforms. Only reimbursed expenditure is measured from a health insurance perspective. Utilization of drugs to treat PD increased by 218% between 2000 and 2010. Reimbursed expenditure increased by 360%, principally driven by increasing utilization of premium-priced patent-protected add-on therapies, including ropinirole and pramipexole. However, following recent reforms, reducing expenditure/defined daily dose for the different drugs, as well as overall expenditure, stabilized reimbursed expenditure between 2005 and 2010. Treatment of PD is complex, and add-on therapies are needed to improve care. Reimbursed expenditure should now fall following stabilization, despite increasing volumes, as successive add-on therapies lose their patents, further increasing prescribing efficiency.

This study compares nurse practitioner (NP) and physician (MD/DO) prescribing patterns for treatment of children with an attention-deficit/hyperactivity disorder (ADHD)-related diagnosis covered by Oregon Medicaid from 2012 to 2013. This study is a limited data set review of Oregon pharmacy claims for youth aged 3-18 at time of prescription fill, who were continuously enrolled for at least 10 months of the index year. Claims with selected ICD-9 codes (n = 197,364) were further defined by 30-day prescriptions and prescription drug events (PDE) linked to each prescriber type of interest. Descriptive statistical analysis of variables included prescriber type (NP vs. physician) and specialty (generalist vs. specialist), child age, and controlled versus noncontrolled drug type. A total of 82,754 complete 30-day prescriptions for 10,753 children from 1785 unique prescribers (78 NP specialists; 303 NP generalists; 162 physician specialists; and 1242 physician generalist prescribers) and 16,669 PDE were analyzed. Physicians prescribed more than 81% of all ADHD medications, and physician generalists prescribed nearly 60% of all prescriptions. Sixty-four percent of 30-day supply prescriptions (n = 52,678) were controlled substances. Generalists, both NPs and physician prescribers, prescribed controlled medications more often than specialists. Physician specialists consistently prescribed controlled substances for all age groups, while NP specialists prescribed more controlled substances as child age increased. Rates of controlled medications prescribed generally increased, as children got older, regardless of provider type. NPs overall prescribe in a similar pattern to physicians when given the authority to prescribe controlled substances for ADHD. Comparisons between prescriber types for controlled substance prescribing by age should be explored further to identify possible variance from national guidelines.

To investigate the national prevalence of potentially inappropriate medications (PIMs) prescribed in ambulatory care clinics in Taiwan according to three different sets of regional criteria and the correlates of PIM use. Cross-sectional study. This analysis included older patients who visited ambulatory care clinics in 2009 and represented half of the older population included on the Taiwanese National Health Insurance Research Database. We identified 1,164,701 subjects who visited ambulatory care clinics and were over 65 years old in 2009. PIM prevalence according to the 2012 Beers criteria, the PIM-Taiwan criteria and the PRISCUS criteria was estimated separately, and characteristics of PIM users were explored. Multivariate logistic regression analysis was used to determine patient factors associated with the use of at least one PIM. Leading PIMs for each set of criteria were also listed. The prevalence of having at least one PIM at the patient level was highest with the Beers criteria (86.2%), followed by the PIM-Taiwan criteria (73.3%) and the PRISCUS criteria (66.9%). Polypharmacy and younger age were associated with PIM use for all three sets of criteria. The leading PIMs detected by the PIM-Taiwan and PRISCUS criteria were all included in the 2012 Beers criteria. Non-COX-selective non-steroidal anti-inflammatory drugs in the Beers criteria and benzodiazepines in the PIM-Taiwan and PRISCUS criteria accounted for most leading PIMs. The prevalence of PIMs was high among older Taiwanese patients receiving ambulatory care visits. The prevalence of PIM and its associated factors varied according to three sets of criteria at the population level. Published by the BMJ Publishing Group Limited.

Objective To assess the effect of physician preference for a particular tumour necrosis factor α (TNF) antagonist on the risk of treatment discontinuation in rheumatoid arthritis. Design Population-based cohort study. Setting British Columbia administrative health data (inpatients, outpatients and pharmacy). Participants 2742 British Columbia residents who initiated a first course of a TNF antagonist between 2001 and December 2008, had been diagnosed with rheumatoid arthritis, and were treated by 1 of 58 medium-volume to high-volume prescribers. Independent variable A level of physician preference for the drug (higher or lower) was assigned based on preceding prescribing records of the care-providing physician. Higher preference was defined as at least 60% of TNF antagonist courses initiated in the preceding year. Sensitivity analysis was conducted with different thresholds for higher preference. Main outcome measure Drug discontinuation was defined as a drug-free interval of 180 days or switching to another TNF antagonist, anakinra, rituximab or abatacept. The risk of discontinuation was compared between different levels of physician preference using survival analysis. Results Higher preference for the prescribed TNF antagonist was associated with improved persistence with the drug (4.28 years (95% CI 3.70 to 4.90) vs 3.27 (2.84 to 3.84), with log rank test p value of 0.017). The adjusted HR for discontinuation was significantly lower in courses of drugs with higher preference (0.85 (0.76 to 0.96)). The results were robust in a sensitivity analysis. Conclusions Higher physician preference was associated with decreased risk of discontinuing TNF antagonists in patients with rheumatoid arthritis. This finding suggests that physicians who strongly prefer a specific treatment help their patients to stay on treatment for a longer duration. Similar research on other treatments is warranted.

Pharmaceutical companies spend significant amount of resources on promotion influencing the prescribing behavior of physicians. Drug promotion can negatively impact on rational prescribing, which may adversely affect the quality of patient care. However, little is known about these activities in Nigeria as the most populous country in Africa. We therefore aimed to explore the nature of encounters between Nigerian physicians and pharmaceutical sales representatives (PSRs), and how these encounters influence prescribing habits. Cross-sectional questionnaire-based study conducted among practicing physicians working in tertiary hospitals in four regions of Nigeria. 176 questionnaires were completed. 154 respondents (87.5%) had medicines promoted to them in the previous three months, with most encounters taking place in outpatients' clinics (60.2%), clinical meetings (46%) and new medicine launches (17.6%). Information about potential adverse effects and drug interactions was provided in 41.5%, and 27.3% of cases, respectively. Food, in the form of lunch or dinner, was the most common form of incentive (70.5%) given to physicians during promotional activities. 61% of physicians felt motivated to prescribe the drug promoted to them, with the quality of information provided being the driving factor. Most physicians (64.8%) would agree to some form of regulation of the relationship between medical doctors and the pharmaceutical industry. Interaction between PSRs and physicians is a regular occurrence in Nigeria, influencing prescribing practices. Meals and cheap gifts were the most common items offered to physicians during their encounters with PSRs. The need for some form of regulation by professional organizations and the government was expressed by most respondents to address current concerns.

Prescribing Errors Involving Medication Dosage Forms

CONTEXT Prescribing errors involving medication dose formulations have been reported to occur frequently in hospitals. No systematic evaluations of the characteristics of errors related to medication dosage formulation have been performed. OBJECTIVE To quantify the characteristics, frequency, and potential adverse patient effects of prescribing errors involving medication dosage forms . DESIGN Evaluation of all detected medication prescribing errors involving or related to medication dosage forms in a 631-bed tertiary care teaching hospital. MAIN OUTCOME MEASURES Type, frequency, and potential for adverse effects of prescribing errors involving or related to medication dosage forms. RESULTS A total of 1,115 clinically significant prescribing errors involving medication dosage forms were detected during the 60-month study period. The annual number of detected errors increased throughout the study period. Detailed analysis of the 402 errors detected during the last 16 months of the study demonstrated the most common errors to be: failure to specify controlled release formulation (total of 280 cases; 69.7%) both when prescribing using the brand name (148 cases; 36.8%) and when prescribing using the generic name (132 cases; 32.8%); and prescribing controlled delivery formulations to be administered per tube (48 cases; 11.9%). The potential for adverse patient outcome was rated as potentially “fatal or severe” in 3 cases (0.7%), and “serious” in 49 cases (12.2%). Errors most commonly involved cardiovascular agents (208 cases; 51.7%). CONCLUSIONS Hospitalized patients are at risk for adverse outcomes due to prescribing errors related to inappropriate use of medication dosage forms. This information should be considered in the development of strategies to prevent adverse patient outcomes resulting from such errors. PMID:12213138

The prevalence of coxib use by dose and duration, and the proportion of persons initially prescribed a high-dose coxib and indications for such use. The estimated daily prevalence of nonaspirin prescription nonsteroidal anti-inflammatory drugs (NSAIDs) was 8.7% in 2002 to 2003 (45.7% coxibs). NSAID use peaked at age 65 to 74 with a prevalence of 19.8% (56.3% coxibs). Doses above the recommended daily dose for osteoarthritis accounted for 33.2% (95% confidence intervals [CIs] 32.4%, 33.9%) of celecoxib use, 14.9% (95% CI 14.4%, 15.5%) of rofecoxib use, and 52.2% (95% CI 50.6%, 53.8%) of valdecoxib use. Most of these prescriptions were for a month's supply. For new coxib users, 13.5% were given a month's supply for the highest dose category, and 28% refilled their prescriptions within 7 days of the end of the original prescription. Of these new chronic high-dose users, 17.2% had ischemic heart disease and 7.1% had heart failure. A substantial portion of coxib prescriptions were for a month's supply at doses above those recommended for most chronic indications. New users were also prescribed high doses despite evidence for cardiovascular comorbidity. These prescribing patterns at doses outside licensed indications are both inappropriate and potentially dangerous.

Using spatial analysis to demonstrate the heterogeneity of the cardiovascular drug-prescribing pattern in Taiwan

PubMed Central

2011-01-01

Background Geographic Information Systems (GIS) combined with spatial analytical methods could be helpful in examining patterns of drug use. Little attention has been paid to geographic variation of cardiovascular prescription use in Taiwan. The main objective was to use local spatial association statistics to test whether or not the cardiovascular medication-prescribing pattern is homogenous across 352 townships in Taiwan. Methods The statistical methods used were the global measures of Moran's I and Local Indicators of Spatial Association (LISA). While Moran's I provides information on the overall spatial distribution of the data, LISA provides information on types of spatial association at the local level. LISA statistics can also be used to identify influential locations in spatial association analysis. The major classes of prescription cardiovascular drugs were taken from Taiwan's National Health Insurance Research Database (NHIRD), which has a coverage rate of over 97%. The dosage of each prescription was converted into defined daily doses to measure the consumption of each class of drugs. Data were analyzed with ArcGIS and GeoDa at the township level. Results The LISA statistics showed an unusual use of cardiovascular medications in the southern townships with high local variation. Patterns of drug use also showed more low-low spatial clusters (cold spots) than high-high spatial clusters (hot spots), and those low-low associations were clustered in the rural areas. Conclusions The cardiovascular drug prescribing patterns were heterogeneous across Taiwan. In particular, a clear pattern of north-south disparity exists. Such spatial clustering helps prioritize the target areas that require better education concerning drug use. PMID:21609462

Antibiotic overuse is driving the emergence of antibiotic resistance worldwide. Good data on prescribing behaviours of healthcare providers are needed to support antimicrobial stewardship initiatives. This study examined the differences in antibiotic prescribing rates of public and private primary care clinics in Malaysia. We used data from the National Medical Care Survey (NMCS), a nationwide cluster sample of Malaysian public and private primary care clinics in 2014. NMCS contained demographic, diagnoses and prescribing from 129 public clinics and 416 private clinics. We identified all encounters who were prescribed antibiotic and analyse the prescribing rate, types of antibiotics, and diagnoses that resulted in antibiotic. Five thousand eight hundred ten encounters were prescribed antibiotics; antibiotic prescribing rate was 21.1 % (public clinics 6.8 %, private clinics 30.8 %). Antibiotic prescribing was higher in private clinics where they contributed almost 87 % of antibiotics prescribed in primary care. Upper respiratory tract infection (URTI) was the most frequent diagnosis in patients receiving antibiotic therapy and accounted for 49.2 % of prescriptions. Of the patients diagnosed with URTI, 46.2 % received antibiotic treatment (public 16.8 %, private 57.7 %). Penicillins, cephalosporins and macrolides were the most commonly prescribed antibiotics and accounted for 30.7, 23.6 and 16.0 % of all antibiotics, respectively. More recently available broad-spectrum antibiotics such as azithromycin and quinolones were more frequently prescribed in private clinics. Antibiotic prescribing rates are high in both public and private primary care settings in Malaysia, especially in the latter. This study provides evidence of excessive and inappropriate antibiotic prescribing for self-limiting conditions. These data highlights the needs for more concerted interventions targeting both prescribers and public. Improvement strategies should focus on reducing

The marketing authorization for the weight loss drug sibutramine was suspended in 2010 following a major trial that showed increased rates of non-fatal myocardial infarction and cerebrovascular events in patients with pre-existing cardiovascular disease. In routine clinical practice, sibutramine was already contraindicated in patients with cardiovascular disease and so the relevance of these influential clinical trial findings to the 'real World' population of patients receiving or eligible for the drug is questionable. We assessed rates of myocardial infarction and cerebrovascular events in a cohort of patients prescribed sibutramine or orlistat in the United Kingdom. A cohort of patients prescribed weight loss medication was identified within the Clinical Practice Research Datalink. Rates of myocardial infarction or cerebrovascular event, and all-cause mortality were compared between patients prescribed sibutramine and similar patients prescribed orlistat, using both a multivariable Cox proportional hazard model, and propensity score-adjusted model. Possible effect modification by pre-existing cardiovascular disease and cardiovascular risk factors was assessed. Patients prescribed sibutramine (N=23,927) appeared to have an elevated rate of myocardial infarction or cerebrovascular events compared with those taking orlistat (N=77,047; hazard ratio 1.69, 95% confidence interval 1.12-2.56). However, subgroup analysis showed the elevated rate was larger in those with pre-existing cardiovascular disease (hazard ratio 4.37, 95% confidence interval 2.21-8.64), compared with those with no cardiovascular disease (hazard ratio 1.52, 95% confidence interval 0.92-2.48, P-interaction=0.0076). All-cause mortality was not increased in those prescribed sibutramine (hazard ratio 0.67, 95% confidence interval 0.34-1.32). Sibutramine was associated with increased rates of acute cardiovascular events in people with pre-existing cardiovascular disease, but there was a low absolute

Behavioral economics interventions have been shown to effectively reduce the rates of inappropriate antibiotic prescriptions for acute respiratory infections (ARIs). To determine the cost-effectiveness of three behavioral economic interventions designed to reduce inappropriate antibiotic prescriptions for ARIs. Thirty-year Markov model from the US societal perspective with inputs derived from the literature and CDC surveillance data. Forty-five-year-old adults with signs and symptoms of ARI presenting to a healthcare provider. (1) Provider education on guidelines for the appropriate treatment of ARIs; (2) Suggested Alternatives, which utilizes computerized clinical decision support to suggest non-antibiotic treatment choices in lieu of antibiotics; (3) Accountable Justification, which mandates free-text justification into the patient's electronic health record when antibiotics are prescribed; and (4) Peer Comparison, which sends a periodic email to prescribers about his/her rate of inappropriate antibiotic prescribing relative to clinician colleagues. Discounted costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios. Each intervention has lower costs but higher QALYs compared to provider education. Total costs for each intervention were $178.21, $173.22, $172.82, and $172.52, and total QALYs were 14.68, 14.73, 14.74, and 14.74 for the control, Suggested Alternatives, Accountable Justification, and Peer Comparison groups, respectively. Results were most sensitive to the quality-of-life of the uninfected state, and the likelihood and costs for antibiotic-associated adverse events. Behavioral economics interventions can be cost-effective strategies for reducing inappropriate antibiotic prescriptions by reducing healthcare resource utilization.

2011-01-01

Objective To better understand barriers associated with the adoption and use of electronic prescribing of controlled substances (EPCS), a practice recently established by US Drug Enforcement Administration regulation. Materials and methods Prescribers of controlled substances affiliated with a regional health system were surveyed regarding current electronic prescribing (e-prescribing) activities, current prescribing of controlled substances, and expectations and barriers to the adoption of EPCS. Results 246 prescribers (response rate of 64%) represented a range of medical specialties, with 43.1% of these prescribers current users of e-prescribing for non-controlled substances. Reported issues with controlled substances included errors, pharmacy call-backs, and diversion; most prescribers expected EPCS to address many of these problems, specifically reduce medical errors, improve work flow and efficiency of practice, help identify prescription diversion or misuse, and improve patient treatment management. Prescribers expected, however, that it would be disruptive to practice, and over one-third of respondents reported that carrying a security authentication token at all times would be so burdensome as to discourage adoption. Discussion Although adoption of e-prescribing has been shown to dramatically reduce medication errors, challenges to efficient processes and errors still persist from the perspective of the prescriber, that may interfere with the adoption of EPCS. Most prescribers regarded EPCS security measures as a small or moderate inconvenience (other than carrying a security token), with advantages outweighing the burden. Conclusion Prescribers are optimistic about the potential for EPCS to improve practice, but view certain security measures as a burden and potential barrier. PMID:21946239

To describe the pattern of drug consumption among patients with dementia in a geographically defined general population in Catalonia (Spain), and to determine its association with age, gender, type of dementia and severity indicators. Cross-sectional study that included 1,894 cases of dementia registered by the Registry of Dementias of Girona from 2007 to 2009. Prescribed drugs were categorized according to the Anatomical Therapeutic Chemical (ATC) classification. A descriptive analysis of drug consumption was stratified according to age, gender, dementia subtypes and dementia severity. Binary logistic regression models were adjusted to detect the association of these variables with drug consumption according to the ATC groups. The most commonly prescribed drugs were for the central nervous system (CNS) (96.4 %), cardiovascular system (79.4 %) and digestive and metabolic system categories (77.7 %). No significant differences were found between the use of nervous system drugs and age, gender, dementia subtypes or dementia severity. The use of alimentary tract and metabolism related drugs, as well as cardiovascular and blood system drugs, were positively correlated with age and secondary dementia. The prevalence of use of cardiovascular and musculoskeletal drugs was higher in women than in men (OR: 1.34; OR: 1.26 respectively). A negative association was found between the severity of dementia and the use of musculoskeletal drugs (OR: 0.71), while its use was significantly higher in the youngest patients (OR: 1.71). Almost all patients with dementia received a CNS drug, being at risk of inappropriate treatment. Treatment for comorbidities in patients with dementia should not be withheld on the basis of age or dementia severity, but rather on the benefit/risk ratio of its prescription. Further studies are needed to evaluate potentially inappropriate drug use and possible untreated conditions in this population.

Inpatient providers have varying levels of knowledge in managing patients with drug and/or penicillin (PCN) allergy. Our objectives were (1) to survey inpatient providers to ascertain their baseline drug allergy knowledge and preparedness in caring for patients with PCN allergy, and (2) to assess the impact of an educational program paired with the implementation of a hospital-based clinical guideline. We electronically surveyed 521 inpatient providers at a tertiary care medical center at baseline and again 6 weeks after an educational initiative paired with clinical guideline implementation. The guideline informed providers on drug allergy history taking and antibiotic prescribing for inpatients with PCN or cephalosporin allergy. Of 323 unique responders, 42% (95% CI, 37-48%) reported no prior education in drug allergy. When considering those who responded to both surveys (n = 213), we observed a significant increase in knowledge about PCN skin testing (35% vs 54%; P < .001) and loss of PCN allergy over time (54% vs 80%; P < .0001). Among those who reported attending an educational session (n = 62), preparedness to determine if an allergy was severe significantly improved (77% vs 92%; P = .03). Other areas, including understanding absolute contraindications to receiving a drug again and PCN cross-reactivity with other antimicrobials, did not improve significantly. Inpatient providers have drug allergy knowledge deficits but are interested in tools to help them care for inpatients with drug allergies. Our educational initiative and hospital guideline implementation were associated with increased PCN allergy knowledge in several crucial areas. To improve care of inpatients with drug allergy, more research is needed to evaluate hospital policies and sustainable educational tools.

and large-scale studies are undertaken during their post-marketing use to determine the genetic components involved in induction of TdP, routine genotyping of patients remains unrealistic. Even without this pharmacogenetic data, the clinical risk of TdP can already be greatly minimised. Clinically, a substantial proportion of cases of TdP are due to the use of either high or usual dosages of drugs with potential to cause TdP in the presence of factors that inhibit drug metabolism. Therefore, choosing the lowest effective dose and identifying patients with these non-genetic risk factors are important means of minimising the risk of TdP. In view of the common secondary pharmacology shared by these drugs, a standard set of contraindications and warnings have evolved over the last decade. These include factors responsible for pharmacokinetic or pharmacodynamic drug interactions. Among the latter, the more important ones are bradycardia, electrolyte imbalance, cardiac disease and co-administration of two or more QT-prolonging drugs. In principle, if large scale prospective studies can demonstrate a substantial genetic component, pharmacogenetically driven prescribing ought to reduce the risk further. However, any potential benefits of pharmacogenetics will be squandered without any reduction in the clinical risk of TdP if physicians do not follow prescribing and monitoring recommendations.

Prescribing without evidence – pregnancy

PubMed Central

Thomas, Simon H L; Yates, Laura M

2012-01-01

Prescribing of medicines during pregnancy is common, and for some groups of women is essential for maintaining maternal and therefore fetal health. Pregnant women and prescribers are rightly concerned, however, about the potential adverse fetal effects of medicines. These may include fetal death or stillbirth, congenital malformations, developmental impairment, neonatal effects or late carcinogenesis. It is therefore essential that the risks and benefits for mother and fetus are considered carefully before prescribing in pregnancy. This is often challenging because of the paucity of information available. To complicate the issue further, drug pharmacokinetics are commonly altered in pregnancy, potentially affecting optimal dosing as well as interpretation of plasma concentration measurements, with specific information on individual drugs seldom available. Most drugs cross the placenta, especially lipophilic drugs and those with low plasma protein binding. Active membrane transporters also have an important role in enhancing or preventing drug transfer, although this is not yet clearly understood. Animal studies have limited applicability to humans because of species-specific effects, and clinical trials in pregnancy are only undertaken in special circumstances. Prescribers therefore need to rely on observational studies of fetal outcomes following drug exposure in human pregnancy. These often involve limited numbers, and data are also subject to confounding and bias, making interpretation difficult. It therefore remains essential that appropriate mechanisms for systematic data collection, including congenital malformation registries, teratology information services, pregnancy registers and linked population registries, are maintained and enhanced to increase the amount and quality of information available.

The prescribing behavior to prescribe high-priced drugs has been hypothesized to be related to the increasing drug expenditures in China, but little empirical evidence exists. The purpose of this study was to examine whether Chinese physicians, driven by financial incentives, tend to prescribe high-priced drugs. The 2000-2008 drug data in the Yangtze River Basin Hospitals' Drug Use Analysis System were analyzed to examine the prescription patterns of penicillins and cephalosporins in Shanghai. Among the top-100 drugs (by volume), cephalosporins cost as 1.1- 2.3 times as penicillins and their volume was 1.7-18.2 times. Revenues generated from prescribing cephalosporins were 3.4-24.2 times as those from prescribing penicillins. The tendency of prescribing relatively high-priced drugs was observed given the same chemical name, dosage, and specification but different trade names. Furthermore, high-priced drugs remained on the top-100 list with increasing volumes, while some lower-priced drugs exited from the list due to decreases in volumes. Facing the policy dilemmas, the Chinese government needs to implement a new financially rewarding system in which hospitals and physicians are able to achieve financial gains in a cost-effective way including prescribing similar drugs with lower prices. Reforming hospitals' payment methods is necessary and feasible to reshape financial incentives of healthcare providers. The combination of the global budget policy and financial incentive measures would be likely to change providers' prescribing behaviors towards a cost-effective direction.

The abuse of prescription drugs has increased dramatically since 1990. Persons who overdose on such drugs frequently consume large doses and visit multiple providers. The risk of fatal overdose for different patterns of use of opioid analgesics and sedative/hypnotics has not been fully quantified. Matched case-control study. Cases were 300 persons who died of unintentional drug overdoses in New Mexico during 2006-2008, and controls were 5,993 patients identified through the state prescription monitoring program with matching 6-month exposure periods. Death from drug overdose or death from opioid overdose. Exposures were demographic variables and characteristics of prescription history. Crude and adjusted odds ratios (AOR) were calculated. Increased risk was associated with male sex (AOR 2.4, 95% confidence interval [CI] 1.8-3.1), one or more sedative/hypnotic prescriptions (AOR 3.0, CI 2.2-4.2), greater age (AOR 1.3, CI 1.2-1.4 for each 10-year increment), number of prescriptions (AOR 1.1, CI 1.1-1.1 for each additional prescription), and a prescription for buprenorphine (AOR 9.5, CI 3.0-30.0), fentanyl (AOR 3.5, CI 1.7-7.0), hydromorphone (AOR 3.3, CI 1.4-7.5), methadone (AOR 4.9, CI 2.5-9.6), or oxycodone (AOR 1.9, CI 1.4-2.6). Patients receiving a daily average of >40 morphine milligram equivalents had an OR of 12.2 (CI 9.2-16.0). Patients being prescribed opioid analgesics frequently or at high dosage face a substantial overdose risk. Prescription monitoring programs might be the best way for prescribers to know their patients' prescription histories and accurately assess overdose risk. Wiley Periodicals, Inc.

To document the impact on clinical practice in England of media attention around possible adverse effects of paroxetine. Analysis of national selective serotonin reuptake inhibitor (SSRI) prescribing trends and yellow-card adverse drug reaction reports, 2001-2004. From a steady state in 2001, paroxetine prescribing declined sharply from April 2002, coinciding with a USA regulatory action; the subsequent decline in paroxetine prescribing was 1.87% per month (95% confidence interval - 2.06, -1.68). Other SSRI prescribing increased by 1% per month until a major UK review of SSRIs in children in December 2003, after which prescribing plateaued. Media publicity was associated with short-term peaks in yellow-card reports related to paroxetine. Falls in paroxetine and other SSRI prescribing in the UK coincided, respectively, with regulatory communications from the USA and the UK, but associations may have noncausal or other explanations. Reports of adverse reactions to paroxetine appeared to increase after adverse media publicity about the drug.

Why do general practitioners prescribe antibiotics for upper respiratory tract infections to meet patient expectations: a mixed methods study

Objectives To describe the role patient expectations play in general practitioners (GPs) antibiotic prescribing for upper respiratory tract infections (URTI). Methods Concurrent explanatory mixed methods approach using a cross-sectional survey and semistructured interviews. Settings Primary care GPs in Australia. Participants 584 GPs (response rate of 23.6%) completed the cross-sectional survey. 32 GPs were interviewed individually. Outcome measure Prescribing of antibiotics for URTI. Results More than half the GP respondents to the survey in Australia self-reported that they would prescribe antibiotics for an URTI to meet patient expectations. Our qualitative findings suggest that ‘patient expectations’ may be the main reason given for inappropriate prescribing, but it is an all-encompassing phrase that includes other reasons. These include limited time, poor doctor–patient communication and diagnostic uncertainty. We have identified three role archetypes to explain the behaviour of GPs in reference to antibiotic prescribing for URTIs. The main themes emerging from the qualitative component was that many GPs did not think that antibiotic prescribing in primary care was responsible for the development of antibiotic resistance nor that their individual prescribing would make any difference in light of other bigger issues like hospital prescribing or veterinary use. For them, there were negligible negative consequences from their inappropriate prescribing. Conclusions There is a need to increase awareness of the scope and magnitude of antibiotic resistance and the role primary care prescribing plays, and of the contribution of individual prescribing decisions to the problem of antibiotic resistance.

Drug rash with eosinophilia and systemic symptoms (DRESS) is a severe drug hypersensitivity reaction characterized by rash, fever and multi-organ failure. Limbic encephalitis (LE) is a rare disorder characterized by cognitive dysfunction with memory disturbance, seizures and psychiatric symptoms. We herein present an unusual case of DRESS syndrome due to lamotrigine with reactivation of Epstein-Barr virus, which developed autoimmune LE and syndrome of inappropriate antidiuretic hormone secretion. Discontinuation of lamotrigine, administration of methylprednisolone and intravenous immunoglobulin led to improvement. The LE in this case might have been caused by an autoimmune inflammatory mechanism associated with DRESS syndrome.

During the study period 27% (n=112,069) of veterans who received opioid analgesics also received benzodiazepines. About half of the deaths from drug overdose (n=1185) occurred when veterans were concurrently prescribed benzodiazepines and opioids. Risk of death from drug overdose increased with history of benzodiazepine prescription: adjusted hazard ratios were 2.33 (95% confidence interval 2.05 to 2.64) for former prescriptions versus no prescription and 3.86 (3.49 to 4.26) for current prescriptions versus no prescription. Risk of death from drug overdose increased as daily benzodiazepine dose increased. Compared with clonazepam, temazepam was associated with a decreased risk of death from drug overdose (0.63, 0.48 to 0.82). Benzodiazepine dosing schedule was not associated with risk of death from drug overdose. Among veterans receiving opioid analgesics, receipt of benzodiazepines was associated with an increased risk of death from drug overdose in a dose-response fashion. © Park et al 2015.

The aim is to evaluate the association between the Charlson Comorbidity Index (CCI), polypharmacy, inappropriate medication use and cognitive impairment in long-term care facility patients. A cross-sectional study including 105 long-term care facility residents was performed. The Charlson Comorbidity Index (CCI) was used. Inappropriate drug use (IDU) was defined according to the STOPP (Screening Tool of Older People's Prescriptions) criteria. Univariate analysis to identify variables associated with patient outcome related with cognitive impairment was investigated with χ 2 , Pearson correlation, Fisher exact, and Mann-Whitney U test where appropriate. For the multivariate analysis, the possible factors identified with univariate analysis were further entered into logistic regression analysis. A significant difference was found between gender, CCI and cognitive impairment (p = 0.038, p = 0.01). While every one point increment in the CCI increases the risk of cognitive impairment 3.1 fold (95% CI = 1.8-5.4, p < 0.001), hypertension increases the risk 12 fold (95% CI = 2.5-67.8, p = 0.002). While the correlation between Mini-Mental Status Examination (MMSE) score and polypharmacy is significant (p = 0.015), the correlation between MMSE and IDU was insignificant (p = 0.739). The association of urogenital system drugs and dementia was significant (p = 0.044). Comorbidities, especially hypertension and old age, are risk factors for cognitive impairment. Polypharmacy correlates with MMSE and is considered a risk factor for cognitive impairment. Inappropriate medication use is high among long-term care facility residents. More studies on large cohorts are needed regarding optimal drug prescription and detection of specific drugs that may have an impact on cognitive performance.

Drug policy: making effective drugs available without bankrupting the healthcare system.

Laupacis, Andreas; Anderson, Geoffrey; O'Brien, Bernie

To the extent possible, drug policy should be based upon good quality evidence. This must extend beyond the traditional focus on efficacy and safety in carefully selected patients, to evidence about real-world effectiveness, cost-effectiveness and safety of drugs. This paper will consider methods of improving the quality of the evidence currently available, and the implications of requiring that evidence. Historically, there has been a direct link between research evidence and policy at the level of licensing - drugs are only made available after they have been shown to be safe and efficacious in well-designed and independently assessed research studies. We propose that this reliance on evidence be logically extended to cover the formulary inclusion and post-marketing surveillance aspects of modern prescription drug policy. More specifically we propose that the decision to initially list a drug on a benefit formulary be based on evidence from relevant head-to-head comparisons and well-designed cost-effectiveness analyses. This evidence would be produced by industry in cooperation with independent peer-reviewed funding agencies. Drugs could only be added to a formulary if they met specific predetermined criteria, and drugs could be removed as superior alternatives became available. The provincial governments are monopsony buyers of medicines, and they wield the power to determine public payer "market access'for medicines. This power (within and across provinces) could be used more effectively to negotiate price in the context of reimbursement. The effect of different methods of influencing prescribing (e.g., 'limited access?) upon drug utilization and patient outcomes should be rigorously assessed, including the randomization of groups of patients or communities to different strategies. We also propose that all drugs on the formulary would be subject to a well-designed post-marketing surveillance program. This program would build on the existing passive reporting of

Carisoprodol, a centrally acting muscle relaxant indicated for acute lower back pain, has been available in Europe and the United States since 1959. Studies indicating increased risk of abuse or addiction led to withdrawal of the drug from the market in Norway and other EU countries in 2008. In this nationwide longitudinal prescription study of 53,116 individuals in Norway, previous users of carisoprodol switched, to a limited extent, to other prescribed drugs with abuse potential after the withdrawal.

For at least two decades, concerns have been raised about inappropriate psychotropic prescribing in Australian residential aged care facilities, due to their modest therapeutic benefit and increased risk of falls and mortality. To date, the majority of prevalence data has been collected in Sydney exclusively and it is not known if recent initiatives to promote appropriate psychotropic prescribing have impacted utilisation. Thus, we aimed to comprehensively analyse psychotropic use in a large national sample of residential aged care facility residents. A cross-sectional, retrospective cohort study of residents from 150 residential aged care facilities distributed nationally during April 2014-October 2015. Antipsychotic, anxiolytic/hypnotic and antidepressant utilisation was assessed, along with anticonvulsant and anti-dementia drug use. Negative binomial regression analysis was used to examine variation in psychotropic use. Full psychotropic prescribing data was available from 11,368 residents. Nearly two-thirds (61%) were taking psychotropic agents regularly, with over 41% prescribed antidepressants, 22% antipsychotics and 22% of residents taking benzodiazepines. Over 30% and 11% were charted for 'prn' (as required) benzodiazepines and antipsychotics, respectively. More than 16% of the residents were taking sedating antidepressants, predominantly mirtazapine. South Australian residents were more likely to be taking benzodiazepines ( p < 0.05) and residents from New South Wales/Australian Capital Territory less likely to be taking them ( p < 0.01), after adjustment for rurality and size of residential aged care facility. Residents located in New South Wales/Australian Capital Territory were also significantly less likely to take antidepressants ( p < 0.01), as were residents from outer regional residential aged care facilities ( p < 0.01). Antipsychotic use was not associated with State, rurality or residential aged care facility size. Regular

Since economic liberalization in the late 1970s, China's health care providers have grown heavily reliant on revenue from drugs, which they both prescribe and sell. To curb abuse and to promote the availability, safety, and appropriate use of essential drugs, China introduced its national essential drug list in 2009 and implemented a zero markup policy designed to decouple provider compensation from drug prescription and sales. We collected and analyzed representative data from China's township health centers and their catchment-area populations both before and after the reform. We found large reductions in drug revenue, as intended by policy makers. However, we also found a doubling of inpatient care that appeared to be driven by supply, instead of demand. Thus, the reform had an important unintended consequence: China's health care providers have sought new, potentially inappropriate, forms of revenue.

Tablet splitting or pill splitting frequently occurs in daily medical practice. For drugs with special pharmacokinetic characters, such as drugs with narrow therapeutic index (NTI), unequal split tablets might lead to erroneous dose titration and it even cause toxicity. The aim of this study was to investigate the frequency of prescribing split NTI drugs at ambulatory setting in Taiwan. A population-based retrospective study was conducted using the National Health Insurance Research Database in Taiwan. All ambulatory visits were analyzed from the longitudinal cohort datasets of the National Health Insurance Research Database. The details of ambulatory prescriptions containing NTI drugs were extracted by using the claims datasets of one million beneficiaries from National Healthcare Insurance Research Database in 2010 in Taiwan. The analyses were stratified by dosage form, patient age and the number of prescribed tablets in a single dose for each NTI drugs. Main outcome measures Number and distinct dosage forms of available NTI drug items in Taiwan, number of prescriptions involved split NTI drugs, and number of patients received split NTI drugs. A total of 148,548 patients had received 512,398 prescriptions of NTI drugs and 41.8 % (n = 62,121) of patients had received 36.3 % (n = 185,936) of NTI drug prescriptions in form of split tablets. The percentage of splitting was highest in digoxin prescriptions (81.0 %), followed by warfarin (72.0 %). In the elderly patients, split tablets were very prevalent with digoxin (82.4 %) and warfarin (84.5 %). NTI drugs were frequently prescribed to be taken in split forms in Taiwan. Interventions may be needed to provide effective and convenient NTI drug use. Further studies are needed to evaluate the clinical outcome of inappropriate split NTI drugs.

Background and Objectives: Inappropriate antimicrobial prescribing is highly reported in dentistry. The objective of the study was to see the effect of dental qualification and practice settings on antimicrobial prescribing practices among dental practitioners in Delhi and National Capital Region (NCR) of India. Materials and Methods: A self-designed and pretested questionnaire was given to 667 dental practitioners holding degrees of graduation, postgraduation, and those pursuing postgraduation, working in academic institutions and private clinics in NCR of India. Data were analyzed using statistical software Stata version 12.0. Chi-square and logistic regression tests were used for analysis. Results: Out of total 539 responded, 66.4% of the practitioners prescribed by brand name and 27.8% by generic name. Amoxicillin + clavulanic acid (27.4%) was the first choice. Only 26% of the practitioners asked for antimicrobial susceptibility testing. Space infections (91.9%), impacted third molar extractions (89.7%), and periodontal abscess (88.1%) were the conditions where antimicrobials were most frequently prescribed. However, 60.9% and 53.3% of the practitioners also prescribed antimicrobials for acute pulpitis and dry socket, respectively. For prophylaxis in medical conditions, amoxicillin was the first choice. In case of history of allergy to penicillin, 52.3% of the practitioners prescribe erythromycin whereas 14.6% prescribe amoxicillin. The adverse drug reporting culture was negligible, and only 14.3% of the practitioners were aware of the Pharmacovigilance Program of India. Level of qualification had a significant effect on prescribing (P < 0.05). Interpretation and Conclusion: Frequent irrational prescribing of antimicrobials used in odontogenic conditions warrants an urgent and continued need for guidelines as well as educational intervention programs in dentistry. This will improve the quality of antimicrobial prescribing practices in dentistry. PMID:28781493

Aims The sources of prescribing information are legion but there is little knowledge about which are actually used in practice by doctors when prescribing. The aims of this study were to determine the sources of prescribing information considered important by doctors, establish which were used in practice, and investigate if hospital and primary care physicians differed in their use of the sources. Methods Two hundred general practitioners (GPs) and 230 hospital doctors were asked to rate information sources in terms of their importance for prescribing ‘old’ and ‘new’ drugs, and then to name the source from which information about the last new drug prescribed was actually derived. Results Among 108 GPs, the Drugs and Therapeutics Bulletin and medical journal articles were most frequently rated as important for information on both old and new drugs while pharmaceutical representatives and hospital/consultant recommendations were more important for information on new drugs, as opposed to old. In practice, information on the last new drug prescribed was derived from pharmaceutical representatives in 42% of cases and hospital/consultant recommendations in 36%, with other sources used infrequently. Among 118 hospital doctors, the British National Formulary (BNF) and senior colleagues were of greatest theoretical importance. In practice, information on the last new drug prescribed was derived from a broad range of sources: colleagues, 29%; pharmaceutical representatives, 18%; hospital clinical meetings, 15%; journal articles, 13%; lectures, 10%. GPs and hospital doctors differed significantly in their use of pharmaceutical representatives (42% vs 18%) and colleagues (7% vs 29%) as sources of prescribing information (P < 0.0001 for both). Conclusions The sources most frequently rated important in theory were not those most used in practice, especially among GPs. Both groups under-estimated the importance of pharmaceutical representatives. Most importantly, the

Medication errors such as potential inappropriate prescriptions would induce serious adverse drug events to patients. Information technology has the ability to prevent medication errors; however, the pharmacology of traditional Chinese medicine (TCM) is not as clear as in western medicine. The aim of this study was to apply the appropriateness of prescription (AOP) model to identify potential inappropriate TCM prescriptions. We used the association rule of mining techniques to analyze 14.5 million prescriptions from the Taiwan National Health Insurance Research Database. The disease and TCM (DTCM) and traditional Chinese medicine-traditional Chinese medicine (TCMM) associations are computed by their co-occurrence, and the associations' strength was measured as Q-values, which often referred to as interestingness or life values. By considering the number of Q-values, the AOP model was applied to identify the inappropriate prescriptions. Afterwards, three traditional Chinese physicians evaluated 1920 prescriptions and validated the detected outcomes from the AOP model. Out of 1920 prescriptions, 97.1% of positive predictive value and 19.5% of negative predictive value were shown by the system as compared with those by experts. The sensitivity analysis indicated that the negative predictive value could improve up to 27.5% when the model's threshold changed to 0.4. We successfully applied the AOP model to automatically identify potential inappropriate TCM prescriptions. This model could be a potential TCM clinical decision support system in order to improve drug safety and quality of care. Copyright © 2016 John Wiley & Sons, Ltd.

We aimed to reliably describe the pattern of outpatient prescription of non-steroidal anti-inflammatory drugs (NSAIDs) and antibiotics (ATBs) at a central hospital in the West Bank, Palestine. This was a retrospective, cross-sectional study investigating a cohort of 2,208 prescriptions ordered by outpatient clinics and the emergency room over one year in Beit Jala Hospital in Bethlehem, West Bank. The orders were analysed for the rate and types of NSAIDs and ATBs utilised, and the appropriateness of these drugs to the diagnosis. Of the total prescriptions, 410 contained NSAIDs (18.6%), including diclofenac (40.2%), low dose aspirin (23.9%), ibuprofen (17.8%) and indomethacin (15.1%). A minority of these prescriptions contained a combination of these agents (2.5%). Only one prescription contained cyclooxyeganse-2 inhibitors (0.2%). The appropriateness of NSAID use to the diagnosis was as follows: appropriate (58.3%), inappropriate (14.4%) and difficult to tell (27.3%). The rate of ATB use was 30.3% (669 prescriptions). The ATBs prescribed were amoxicillin (23.3%), augmentin (14.3%), quinolones (12.7%), first and second generation cephalosporins (9.4% and 12.7%, respectively) and macrolides (7.2%). ATB combinations were identified in 9.4%, with the most common being second-generation cephalopsorins and metronidazole (4.3%). Regarding the appropriateness of prescribing ATBs according to the diagnosis, it was appropriate in 44.8%, inappropriate in 20.6% and difficult to tell in 34.6% of the prescriptions. These findings revealed a relatively large number and inappropriate utilisation of ATBs and NSAIDs. An interventional programme needs to be adopted to reinforce physicians' knowledge of the rational prescription of these agents.

The cost-effectiveness of direct-to-consumer advertising for prescription drugs.

PubMed

Atherly, Adam; Rubin, Paul H

2009-12-01

In this paper we use published information to analyze the economic value of Direct to Consumer Advertising (DTCA). The reviewed research finds that DTCA leads to increased demand for the advertised drug and that the effect of the drug tends to be class-wide rather than product specific. There is weak evidence that DTCA may increase compliance and improve clinical outcomes. However, there is little research on the effect of DTCA on inappropriate prescribing or on the characteristics of patients who respond to treatment. On net, if the advertised drugs are cost effective on average and the patients using the drugs in response to the advertisement are similar to other users, DTCA is likely cost effective. Overall, the literature to date is consistent with the idea that DTCA is beneficial, but further research is needed before definitive conclusions can be drawn.

The rates and reasons why clinicians decide not to follow recommendations from explicit-criteria have been studied scarce. We aimed to compare STOPP version 2 representing one of the most commonly used excplicit tool with the implicit comprehensive geriatric assessment mediated clinical evaluation considered as gold standard. Two hundred and six (n = 206) outpatients ≥65 years old were included. The study was designed as retrospective, cross-sectional, and randomised. STOPP version 2 criteria were systematically used to assess pre-admission treatments followed by implicit clinical evaluation regarding two questions: Were the STOPP criteria recommendations valid for the individual patient and were there any potentially inappropriate-prescription other than depicted by STOPP version 2 criteria? The underlying reason(s) and associated clinical-features were noted. About 62.6% potentially inappropriate-prescriptions were identified (0.6 per-subject) according to systematic application of STOPP v2 while it was 53.4% (0.5 potentially inappropriate-prescriptions per subject) by clinician's application of STOPP v2. Prevalence of non-compliance was 14.7% in 18 (21.7%) of 83 patients identified by systematic application. Suggestion to stop a drug was not accepted because of need of treatment despite likelihood of anticipated side-effects in about 2/3 and with no-anticipated side-effects in about 1/3 of non-compliances. Not following STOPP v2 was significantly associated with lower functional level. According to clinician's implicit-evaluation, there were an extra 59.2% potentially inappropriate-prescriptions (0.6 per subject) in 80 (38.8%) patients yielding a total of 112.6% potentially inappropriate-prescription. Most of the STOPP v2 directed drug cessations are decided valid by the clinicians. In patients with higher functional dependency, it is likely that they are not followed due to palliation focussed care/patient-family preferences. There may be as much as STOPP

Background Medication errors are common among inpatients and many are preventable with computerized prescribing. Relatively little is known about outpatient prescribing errors or the impact of computerized prescribing in this setting. Objective To assess the rates, types, and severity of outpatient prescribing errors and understand the potential impact of computerized prescribing. Design Prospective cohort study in 4 adult primary care practices in Boston using prescription review, patient survey, and chart review to identify medication errors, potential adverse drug events (ADEs) and preventable ADEs. Participants Outpatients over age 18 who received a prescription from 24 participating physicians. Results We screened 1879 prescriptions from 1202 patients, and completed 661 surveys (response rate 55%). Of the prescriptions, 143 (7.6%; 95% confidence interval (CI) 6.4% to 8.8%) contained a prescribing error. Three errors led to preventable ADEs and 62 (43%; 3% of all prescriptions) had potential for patient injury (potential ADEs); 1 was potentially life-threatening (2%) and 15 were serious (24%). Errors in frequency (n=77, 54%) and dose (n=26, 18%) were common. The rates of medication errors and potential ADEs were not significantly different at basic computerized prescribing sites (4.3% vs 11.0%, P=.31; 2.6% vs 4.0%, P=.16) compared to handwritten sites. Advanced checks (including dose and frequency checking) could have prevented 95% of potential ADEs. Conclusions Prescribing errors occurred in 7.6% of outpatient prescriptions and many could have harmed patients. Basic computerized prescribing systems may not be adequate to reduce errors. More advanced systems with dose and frequency checking are likely needed to prevent potentially harmful errors. PMID:16117752

To compare the predictive validity of the 2003 Beers, 2012 American Geriatrics Society (AGS) Beers, and Screening Tool of Older Persons' potentially inappropriate Prescriptions (STOPP) criteria. Retrospective cohort. Managed care administrative claims data from 2006 to 2009. Commercially insured persons aged 65 and older in the United States (N=174,275). Association between adverse drug events (ADEs), emergency department (ED) visits, and hospitalization outcomes and inappropriate medication use using time-varying Cox proportional hazard models. Measures of model discrimination (c-index) and hazard ratios (HRs) were calculated to compare unadjusted and adjusted models for associations. The prevalence of inappropriate prescribing was 34.1% for the 2012 AGS Beers criteria, 32.2% for the 2003 Beers criteria, and 27.6% for the STOPP criteria. Each set of criteria modestly discriminated ADEs in unadjusted analyses (STOPP criteria: hazard ratio (HR)=2.89, 95% confidence interval (CI)=2.68-3.12, C-index=0.607; 2012 AGS Beers criteria: HR=2.51, 95% CI=2.33-2.70, C-index=0.603; 2003 Beers criteria: HR=2.65, 95% CI=2.46-2.85, C-index=0.605). Similar results were observed for ED visits and hospitalizations. The c-indices increased to between 0.65 and 0.70 in adjusted analyses. The kappa for agreement between criteria was 0.80 for the 2003 and 2012 AGS Beers criteria, 0.58 for the 2012 AGS Beers and STOPP criteria, and 0.59 for the 2003 Beers and STOPP criteria. For the three outcomes, the 2012 AGS Beers criteria had the highest sensitivity (61.2-71.2%) and the lowest specificity (41.2-70.7%), and the STOPP criteria had the lowest sensitivity (53.8-64.7%) but the highest specificity (47.8-78.1%). All three criteria were modestly prognostic for ADEs, EDs, and hospitalizations, with the STOPP criteria slightly outperforming both Beers criteria. With low sensitivity, low specificity, and low agreement between the criteria, they can be used in a complementary fashion to enhance

Inappropriate use of antimicrobials is of special importance in the intensive treatment unit because of the large number of drugs prescribed, the chance for drug errors, and the likelihood of development of drug resistance. A total of 297 records of patients admitted to the intensive treatment unit of the Manipal teaching hospital, a tertiary care hospital in Pokhara, western Nepal, were studied to determine the prescribing frequency and rationality of use of antimicrobials. Patient outcome, duration of stay in the intensive treatment unit, and the age and sex distribution of the patients were also studied. Mean+/-SD drugs per patient was 3.4+/-1.8. About half (50.2%) of the patients received an antimicrobial; 84.6% of the antimicrobials were used without obtaining bacteriologic evidence of infection. The commonest organisms isolated on culture were Pseudomonas aeruginosa, Klebsiella pneumoniae, Streptococcus pneumoniae, and Staphylococcus aureus. A total of 28.9% of the antimicrobials were prescribed for lower respiratory tract infections on the basis of the putative site of infection; 61.9% of the antimicrobials were prescribed by the parenteral route and mainly the older generation of antimicrobials were used. In 39 of the 149 patients prescribed an antimicrobial, the use was irrational. Prescriber education to improve prescribing patterns and regular auditing of antimicrobial prescriptions to prevent their inappropriate use and unnecessary cost to the patients are required. The high percentage of inappropriate use of antimicrobials raises concerns about the development and spread of drug resistance, which must be addressed.

In post-war Kosovo, the magnitude of inappropriate use of benzodiazepines is unknown to date. The aim of this study was to assess the prevalence and correlates of continuation of intake of benzodiazepines beyond prescription (referred to as "inappropriate use") in the adult population of Gjilan region in Kosovo. A cross-sectional study was conducted in Gjilan region in 2015 including a representative sample of 780 individuals attending different pharmacies and reporting use of benzodiazepines (385 men and 395 women; age range 18-87 years; response rate: 90%). A structured questionnaire was administered to all participants inquiring about the use of benzodiazepines and socio-demographic characteristics. Overall, the prevalence of inappropriate use of benzodiazepines was 58%. In multivariable-adjusted models, inappropriate use of benzodiazepines was significantly associated with older age (OR 1.7, 95% CI 1.1-2.7), middle education (OR 1.8, 95% CI 1.2-2.7), daily use (OR 1.4, 95% CI 1.1-2.0) and addiction awareness (OR 2.7, 95% CI 2.0-3.8). Furthermore, there was evidence of a borderline relationship with rural residence (OR 1.2, 95% CI 0.9-1.7). Our study provides novel evidence about the prevalence and selected correlates of inappropriate use of benzodiazepines in Gjilan region of Kosovo. Health professionals and policymakers in Kosovo should be aware of the magnitude and determinants of drug misuse in this transitional society.

Studying drug use pattern among medical practitioners is of vital importance in the present scenario where irrational drug use and development of drug resistance is becoming rampant. To assess, the pattern of prescribing practices among the general practitioners in a defined rural and urban area of Tamil Nadu. A community based descriptive study was conducted to collect 600 prescriptions from the catchment areas of rural and urban health training centers of a medical college using prescribing indicators as per the WHO "How to investigate drug use in health facilities" tool. This prescription study revealed that multivitamins (19.5%), antibiotics (19.3%), drugs for gastro-intestinal tract (GIT) (18%), analgesic non-steroidal anti-inflammatory drugs/ (NSAID's) (15.1%), and antihistaminic (12.5%) were prescribed frequently. Among the antibiotics, amoxicillin (49.2%) was the most commonly prescribed followed by gentamicin (31.7%). Percentage of prescriptions with an antibiotic was 55% and nearly 62% of the practitioners prescribed drugs by their generic names. As a practice of poly-pharmacy, it was observed that the average number of drugs prescribed in urban and rural area was nearly 5 and 4, respectively. Nearly 80% of the urban and rural practitioners were prescribing at least one injection. Study of the quality of prescriptions revealed that there was poor legibility, high usage of abbreviations, inadequate details of the drugs, and absence of signature by practitioners in the prescriptions. This study clearly highlights the practice of poly-pharmacy, low usage of generic drugs, injudicious usage of antibiotics and injections and low usage of drugs prescribed from essential drugs list.

Background: The use of antibiotics prophylactically and therapeutically in dentistry has become common practice. Inappropriate prescription may lead to adverse side effects and bacterial resistance. During clinical training, dental students in Saudi Arabia are authorized to prescribe antibiotics. Aim: To evaluate dental students’ knowledge and attitudes regarding antibiotic prescription in Riyadh, Saudi Arabia. Methods: A cross-sectional study based on a validated questionnaire consisting of 34 questions focusing on antibiotic indications in dentistry, antibiotic regimens, and knowledge regarding resistance was distributed amongst dental students in five leading dental colleges in Riyadh. Results: A large proportion of students (71.7%) were familiar with the concept of antibiotic resistance. When comparing junior and senior dental students’ knowledge with regards to indications of antibiotic use in commonly encountered conditions, it was found that there was no significant difference in antibiotic prescription frequency between these groups. Most dental students choose to prescribe amoxicillin as their first-choice of antibiotic (88.4%), and most also chose to use it for a duration of 3⁻5 days (69.2%). Conclusions: This study concludes that dental students may prescribe antibiotics inappropriately to manage various conditions when not indicated. This may indicate a defect in education of students with regards to current antibiotic guidelines.

Many patients unnecessarily receive proton-pump inhibitor (PPI) drugs long term with significant financial and safety implications. Educating, empowering and supporting patients to self-manage their symptoms can lead to significant and sustained reductions in PPI prescribing. We aimed to implement a programme to reduce inappropriate PPI prescribing. Eligible patients in one general medical practice in rural Scotland were invited for participation between November 2008 and February 2010. Patients attended special nurse advisor clinics, completed dyspepsia questionnaires, received information, formulated self-management plans and were offered flexible support. Of the study population, 437/2883 (15%) were prescribed PPIs. Of these, 166 (38%) were judged eligible for participation. After 12 months, 138/157 (83%) had reduced or stopped their PPIs, while 19/157 (11%) had reverted. The estimated annual net saving in the prescribing budget was ?3180.67. Self-reported understanding of symptom self-management increased from 6/20 (30%) to 18/20 (90%) patients after participation in the programme. A patient-centred programme delivered by a specialist nurse significantly reduced PPI prescribing with financial and potential therapeutic benefits. The vast majority of eligible patients were able to 'step down and off' or 'step off' PPI use after 12 months without any complications or deteriorating symptom control. Further research with larger cohorts of practices and patients is needed to develop a feasible, acceptable and effective programme if similar benefits are to be achieved for primary care in general.

National indicators for quality of drug therapy in older persons: the Swedish experience from the first 10 years.

Inappropriate drug use is an important health problem in elderly persons. Beginning with the Beers' criteria in the early 1990s, explicit criteria have been extensively used to measure and improve quality of drug use in older people. This article describes the Swedish indicators for quality of drug therapy in the elderly, introduced in 2004 and updated in 2010. These indicators were designed to be applied to people aged 75 years and over, regardless of residence and other characteristics. The indicators are divided into drug specific, covering choice, indication and dosage of drugs, polypharmacy, drug-drug interactions (DDIs), drug use in decreased renal function and in some symptoms; and diagnosis specific, covering the rational, irrational and hazardous drug use in common disorders in elderly people. During the 10 years since introduction, the Swedish indicators have several applications. They form the basis for recommendations for drug therapy in older people, are implemented in prescribing supports and drug utilisation reviews, are used in national benchmarking of the quality of Swedish healthcare and have contributed to initiatives from pensioner organisations. The indicators have also been used in several pharmacoepidemiological studies. Since 2005, there have been signs of improvement of the quality of drug prescribing to elderly persons in Sweden. For example, the prescribing of drugs that should be avoided in older persons decreased by 36 % between 2006 and 2012 in persons aged 80 years and older. Similarly, drug combinations that may cause DDIs decreased by 26 % and antipsychotics by 41 %. The indicators have likely contributed to this.

What do we know about direct-to-consumer advertising of prescription drugs?

PubMed

Calfee, John E

2003-01-01

Two papers, by Joel Weissman and colleagues and by Robert Dubois, add to our limited knowledge of the effects of direct-to-consumer (DTC) advertising of prescription drugs. Their results reinforce the largely positive findings from consumer surveys, while adding valuable new data and insights. These suggest that DTC ads probably improve patients' health outcomes and do not tend to lead to inappropriate prescribing. DTC advertising is emerging as a positive force in health care markets, consistent with what is known about the effects of advertising in many other markets.

Background/Objectives: The marketing authorization for the weight loss drug sibutramine was suspended in 2010 following a major trial that showed increased rates of non-fatal myocardial infarction and cerebrovascular events in patients with pre-existing cardiovascular disease. In routine clinical practice, sibutramine was already contraindicated in patients with cardiovascular disease and so the relevance of these influential clinical trial findings to the ‘real World' population of patients receiving or eligible for the drug is questionable. We assessed rates of myocardial infarction and cerebrovascular events in a cohort of patients prescribed sibutramine or orlistat in the United Kingdom. Subjects/Methods: A cohort of patients prescribed weight loss medication was identified within the Clinical Practice Research Datalink. Rates of myocardial infarction or cerebrovascular event, and all-cause mortality were compared between patients prescribed sibutramine and similar patients prescribed orlistat, using both a multivariable Cox proportional hazard model, and propensity score-adjusted model. Possible effect modification by pre-existing cardiovascular disease and cardiovascular risk factors was assessed. Results: Patients prescribed sibutramine (N=23 927) appeared to have an elevated rate of myocardial infarction or cerebrovascular events compared with those taking orlistat (N=77 047; hazard ratio 1.69, 95% confidence interval 1.12–2.56). However, subgroup analysis showed the elevated rate was larger in those with pre-existing cardiovascular disease (hazard ratio 4.37, 95% confidence interval 2.21–8.64), compared with those with no cardiovascular disease (hazard ratio 1.52, 95% confidence interval 0.92–2.48, P-interaction=0.0076). All-cause mortality was not increased in those prescribed sibutramine (hazard ratio 0.67, 95% confidence interval 0.34–1.32). Conclusions: Sibutramine was associated with increased rates of acute cardiovascular events in

Background Recent studies on prescribing among outpatients in hospitals in Western Nepal are lacking. The main objectives of the study were to obtain information on the morbidity pattern among outpatients and to analyze prescribing using drug use indicators. Methods A retrospective hospital record based study from 01.01.2004 to 31.12.2004 was carried out among individuals attending the outpatient department (OPD) of the Manipal Teaching hospital, Pokhara, Western Nepal. A total of 32,017 new patients attended the OPD during the study period. Systematic random sampling (1 in every 20 patients) was done and 1600 patients selected. After excluding patients visiting the emergency department, those who got admitted and whose records were not available, 1261 cases were analyzed. The demographic details, morbidity pattern, average number of drugs prescribed, percentage of drugs prescribed by generic names and from the Essential drug list of Nepal (Essential drugs are those which satisfy the priority healthcare needs of the population), percentage of encounters with an antibiotic and an injection prescribed were noted. Results 1261 patients made 1772 visits. Upper respiratory tract infection and acid peptic disease were the most common diagnoses. The mean number of drugs was 1.99. Only 19.5% and 39.6% of drugs were prescribed by generic name and from the Essential drug list. Antibiotics and injections were prescribed in 26.4% and 0.96% of encounters. Cetrizine, vitamins, amoxicillin, the combination of paracetamol and ibuprofen and ranitidine were most commonly prescribed. Conclusions Upper respiratory tract infections and acid peptic disease were the common illnesses. Generic prescribing and use of essential drugs were low. Some of the drug combinations being used were irrational. Prescriber education may be helpful in encouraging rational prescribing. PMID:18523618

Influencing prescribing in English primary care: the views of primary care organisations.

The rapid rise of prescribing expenditure is a concern in many industrialised countries and methods to manage medicines are widely employed. The purpose of this study was to identify the approaches to improve primary care prescribing by primary care organisations (PCOs) in the National Health Service (NHS) in England. A questionnaire (Management of Medicines, MANMED) was mailed to prescribing advisers and prescribing leads in 332 PCOs. A response rate of 66% (220/332) was achieved. Most PCOs report the improvement of the quality of prescribing as their top priority, followed by budget adherence at both practice and PCO levels. Prescribing advisers typically offer several forms of support: practice visits, prescribing reviews, indicators of prescribing, prescribing newsletters, hands-on support, seminars and local formularies. PCOs are pursuing a wide range of prescribing initiatives, covering, on average, seven different therapeutic areas. National targets are the main driver for prescribing initiatives but other key influences include inappropriate prescribing and clinical governance. Although cost considerations are important, improving the quality of prescribing is perceived as the overriding principle on which PCO prescribing strategy is based. Multifaceted prescribing support is widespread and national targets are the largest single factor influencing choice of therapeutic area for prescribing initiatives. Diversity in approaches presents the opportunity to improve the evidence base for medicines management. Not only could such research inform PCOs in their central aim of improving the quality of prescribing within the NHS, but it may also offer insights of relevance to other countries if the influence of process and context upon the effectiveness of medicines management is systematically explored.

The penetration of generic drugs in the Greek pharmaceutical market is placed among the weakest in the EU. The Greek regulatory framework does not systematically support the development of this subsector and physicians are not provided with incentives for prescribing generics. The aim of this study was to investigate the prescribing profile of physicians in Greece with a focus on the factors that influence their decision on generics prescribing. A structured questionnaire was sent by mail to a random national sample of 1463 physicians, stratified by sex, specialty and geographical region. The response rate was 82.3%. Greek physicians have a positive view on generics but they prefer to prescribe the original products. According to our analysis, physician's age and their opinion on generics' efficacy and effectiveness are identified as important determinants of their prescribing decision. The primary reason that could make them change their prescribing habits is the appearance of side-effects. Patients' insurance coverage and income, as well as the drug cost are also referred as factors that influence their prescribing decision. Despite the fact that they do not usually prescribe generics in their clinical practice, they are willing to substitute an original drug by a generic product. Our findings suggest that Greek physicians could be persuaded to prescribe generic medicines, if a generic promotion policy was introduced in the country. To develop such a policy, a set of supply side and demand-side measures should be implemented along with provision of information on generics to physicians during their education and clinical practice.

In order to assess biases occurring in primary care prescription studies, we compared non-steroidal anti-inflammatory drug (NSAID) prescribing patterns reported by general practitioners directly (GP-based survey) and from a pharmacy-based survey of general practitioner prescribing (pharmacy-based survey). Volunteer GPs of the administrative area of Côte d'Or (France) returned a mailed questionnaire on NSAID prescribing patterns for consecutive patients seen during a 2-month period. In order to obtain a reference basis, pharmacies of the same administrative area provided all prescriptions that included NSAIDs during a 1-week period originating in general practice. The rate of participation was 25% for the GPs and 40% for the pharmacies. Participant GPs were representative of GPs of the area with regard to sex, year of graduation and practice area but pharmacies from rural areas were over-represented. The GP-based survey and the pharmacy-based survey provided respectively 770 and 1050 prescriptions. There were no differences between either survey in the type of NSAIDs prescribed and in the most frequently associated drugs. GPs who volunteered in the GP survey prescribed NSAIDs more frequently orally and at higher doses than GPs involved in the pharmacy-based survey. They also prescribed more gastroprotective drugs, especially in the elderly. None of these results could be explained by differences in patient characteristics and GP practice areas. GPs who actively participate in prescription surveys exhibit prescribing patterns that fit better with official recommendations than the average. Although selection biases cannot be ruled out, it is suggested that some changes in GP prescription habits may have been induced by the survey itself.

Antipsychotic medications are routinely prescribed in nursing homes to address the behavioral and psychological symptoms of dementia. Unfortunately, inappropriate prescribing of antipsychotic medications is common and associated with increased morbidity, adverse drug events, and hospitalizations. Multifaceted interventions can achieve a 12-20 % reduction in antipsychotic prescribing levels in nursing homes. Effective interventions have featured educational outreach and ongoing performance feedback. This pragmatic, cluster-randomized control trial and embedded process evaluation seeks to determine the effect of adding academic detailing to audit and feedback on prescribing of antipsychotic medications in nursing homes, compared with audit and feedback alone. Nursing homes within pre-determined regions of Ontario, Canada, are eligible if they express an interest in the intervention. The academic detailing intervention will be delivered by registered health professionals following an intensive training program including relevant clinical issues and techniques to support health professional behavior change. Physicians in both groups will have the opportunity to access confidential reports summarizing their prescribing patterns for antipsychotics in comparison to the local and provincial average. Participating homes will be allocated to one of the two arms of the study (active/full intervention versus standard audit and feedback) in two waves, with a 2:1 allocation ratio. Homes will be randomized after stratifying for geography, baseline antipsychotic prescription rates, and size, to ensure a balance of characteristics. The primary outcome is antipsychotic dispensing in nursing homes, measured 6 months after allocation; secondary outcomes include clinical outcomes and healthcare utilization. Policy-makers and the public have taken note that antipsychotics are used in nursing homes in Ontario far more than other jurisdictions. Academic detailing can be an effective

Drug overdose is the leading cause of injury death in the United States. The death rate from drug overdose in the United States more than doubled during 1999-2013, from 6.0 per 100,000 population in 1999 to 13.8 in 2013. The increase in drug overdoses is attributable primarily to the misuse and abuse of prescription drugs, especially opioid analgesics, sedatives/tranquilizers, and stimulants. Such drugs are prescribed widely in the United States, with substantial variation by state. Certain patients obtain drugs for nonmedical use or resale by obtaining overlapping prescriptions from multiple prescribers. The risk for overdose is directly associated with the use of multiple prescribers and daily dosages of >100 morphine milligram equivalents (MMEs) per day. 2013. The Prescription Behavior Surveillance System (PBSS) is a public health surveillance system that allows public health authorities to characterize and quantify the use and misuse of prescribed controlled substances. PBSS began collecting data in 2012 and is funded by CDC and the Food and Drug Administration. PBSS uses standard metrics to measure prescribing rates per 1,000 state residents by demographic variables, drug type, daily dose, and source of payment. Data from the system can be used to calculate rates of misuse by certain behavioral measures such as use of multiple prescribers and pharmacies within specified time periods. This report is based on 2013 de-identified data (most recent available) that represent approximately one fourth of the U.S. Data were submitted quarterly by prescription drug monitoring programs (PDMPs) in eight states (California, Delaware, Florida, Idaho, Louisiana, Maine, Ohio, and West Virginia) that routinely collect data on every prescription for a controlled substance to help law enforcement and health care providers identify misuse or abuse of such drugs. In all eight states, opioid analgesics were prescribed approximately twice as often as stimulants or benzodiazepines

Anemia is common in several patient populations, including those with chronic kidney disease, cancer, and HIV/AIDS, and may require treatment with erythropoietin-stimulating agents (ESAs). Given the potential risks of the ESA, epoetin, and the significant costs associated with this agent, a large teaching medical institution developed a the drug-utilization management program using evidence-based guidelines on appropriate use. This study was designed to determine the clinical and financial impact of the drug-utilization management program. This retrospective cohort study was conducted at the medical institution that implemented the program using clinical pharmacists. Patients were included if epoetin was administered during their hospital stay (evaluation period, December 1, 2010, to December 31, 2011). The rate of inappropriate epoetin prescribing and the economic impact of guideline implementation were evaluated using comparisons of data from cohorts prescribed epoetin before and after guideline implementation. Data from 796 patients were included in the analyses (pre-implementation, 496; post-implementation, 300). The proportion of patients prescribed epoetin was significantly smaller after guideline implementation (2.4% vs 1.6%; P < 0.001). The reduction in the total number of epoetin units administered was 45%. The significant reduction (25%) in inappropriate prescribing after guideline implementation was primarily attributed to a 17% decrease in epoetin use in nonspecific anemia. The reduction in inappropriate epoetin prescribing translated into a 23.8% reduction in costs (P < 0.001) associated with inappropriate epoetin use. The estimated annual cost-savings of this program was $198,352 ($16,529/mo). The implementation of a drug-utilization management program using clinical pharmacists who evaluated epoetin was associated with a decrease in inappropriate epoetin prescribing and with significant cost-savings.

Background Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used pharmaceutical agents worldwide. NSAIDs are considered nephrotoxic and should therefore be used with caution or be avoided completely in high risk patients, such as chronic kidney disease (CKD) patients. Objective This study aimed to investigate the prescribing of NSAIDs in CKD patients in order to generate awareness and improve the outcome of these patients. Setting The study was conducted using medicine claims data in the private health sector of South Africa. Method A descriptive, quantitative study was performed, using retrospective data obtained from a Pharmaceutical Benefit Management company. Data from 1 January 2009 to 31 December 2013 were analysed. The study population consisted of all patients with an ICD-10 code for a CKD (N18), in association with a paid claim for an NSAID. Main outcome measure The stratification of NSAID prescribing volume among the CKD population in terms of gender, age, NSAID type, dosage and prescriber type. Results The prescribing of NSAIDs in CKD patients varied between 26 and 40 % over the 5 year study period. No association between gender and CKD patients who received NSAIDs versus those who did not was found, with p > 0.05 and Cramer's V < 0.1 for each year of the study. The association between age groups and CKD patients who received NSAIDs versus those who did not was statistically significant, but practically weak (p < 0.05; Cramer's V ≥ 0.1). Most NSAID prescriptions (52-63 %) were for patients aged 35-64 years. Diclofenac (34.25 %) was the single most frequently prescribed NSAID, but the COX-2-inhibitors (celecoxib, meloxicam and etoricoxib) were the preferred NSAID class to be prescribed. The majority (61.6 %) of the NSAIDs were prescribed by general medical practitioners in dosages meeting and even exceeding the recommended daily dosage of patients with normal kidney function. Conclusions Even though NSAIDs are

Medication prescribing is a complex process where the focus tends to be on starting new medication, changing a drug regimen, and continuing a drug regimen. On occasion, a prudent approach to prescribing may necessitate ending an ongoing course of medication, either because it should not have been started in the first place; because its continued use would cause harm; or because the medication is no longer effective. To identify effective strategies for stopping pre-existing prescribing in situations where continued prescribing may no longer be clinically warranted. Systematic searches for English-language reports of experimental and quasi-experimental research were conducted in PubMed (1951-November 2009), EMBASE (1966-September 2008), and International Pharmaceutical Abstract b (1970-September 2008). A manual search for relevant review articles and a keyword search of a local database produced by a previous systematic search for prescribing influence and intervention research were also conducted. Following initial title screening for relevance 2 reviewers, using formal assessment and data extraction tools, independently assessed abstracts for relevance and full studies for quality before extracting data from studies selected for inclusion. Of 1306 articles reviewed, 12 were assessed to be of relevant, high-quality research. A variety of drugs were examined in the included studies with benzodiazepines the most common. Studies included in the review tested 9 different types of interventions. Effective interventions included patient-mediated interventions, manual reminders to prescribers, educational materials given to patients, a face-to-face intervention with prescribers, and a case of regulatory intervention. Partially effective interventions included audit and feedback, electronic reminders, educational materials alone sent to prescribers, and distance communication combined with educational materials sent to prescribers. It appears possible to stop the

Polypharmacy is frequent in the elderly population and is associated with potentially drug inappropriateness and drug-related problems. To assess the effectiveness and safety of a medication evaluation programme for community-dwelling polymedicated elderly people. Randomized, open-label, multicentre, parallel-arm clinical trial with 1-year follow-up. Primary care centres. Polymedicated (≥8 drugs) elderly people (≥70 years). Pharmacist review of all medication according to the Good Palliative-Geriatric Practice algorithm and the Screening Tool of Older Person's Prescriptions-Screening Tool to Alert Doctors to the Right Treatment criteria and recommendations to the patient's physician. Routine clinical practice. Recommendations and changes implemented, number of prescribed drugs, restarted drugs, primary care and emergency department consultations, hospitalizations and death. About 503 (252 intervention and 251 control) patients were recruited and 2709 drugs were evaluated. About 26.5% of prescriptions were rated as potentially inappropriate and 21.5% were changed (9.1% discontinuation, 6.9% dose adjustment, 3.2% substitution and 2.2% new prescription). About 2.62 recommendations per patient were made and at least one recommendation was made for 95.6% of patients. The mean number of prescriptions per patient was significantly lower in the intervention group at 3- and 6-month follow-up. Discontinuations, dose adjustments and substitutions were significantly higher than in the control group at 3, 6 and 12 months. No differences were observed in the number of emergency visits, hospitalizations and deaths. The study intervention was safe, reduced potentially inappropriate medication, but did not reduce emergency visits and hospitalizations in polymedicated elderly people. © The Author 2016.

2011-01-01

For many disorders, patient heterogeneity requires physicians to customize their treatment to each patient’s needs. We test for the existence of customization in physicians’ prescribing for bipolar disorder, using data from a naturalistic clinical effectiveness trial of bipolar disorder treatment (STEP-BD), which did not constrain physician prescribing. Multinomial logit is used to model the physician’s choice among five combinations of drug classes. We find that our observed measure of the patient’s clinical status played only a limited role in the choice among drug class combinations, even for conditions such as mania that are expected to affect class choice. However, treatment of a patient with given characteristics differed widely depending on which physician was seen. The explanatory power of the model was low. There was variation within each physician’s prescribing, but the results do not suggest a high degree of customization in physicians’ prescribing, based on our measure of clinical status.

The misuse, abuse and diversion of controlled substances have reached epidemic proportion in the United States. Contributing to this problem are providers who over-prescribe these substances. Using one state's prescription drug monitoring program, we describe a series of metrics we developed to identify providers manifesting unusual and uncustomary prescribing practices. We then present the results of a preliminary effort to assess the concurrent validity of these algorithms, using death records from the state's vital records database pertaining to providers who wrote prescriptions to patients who then died of a medication or drug overdose within 30 days. Metrics manifesting the strongest concurrent validity with providers identified from these records related to those who co-prescribed benzodiazepines (e.g., valium) and high levels of opioid analgesics (e.g., oxycodone), as well as those who wrote temporally overlapping prescriptions. We conclude with a discussion of a variety of uses to which these metrics may be put, as well as problems and opportunities related to their use.

What use is generic prescribing?

PubMed Central

Archer, Michael

1985-01-01

The dispensing of generic preparations at four dispensing chemist shops was investigated by means of a questionnaire. Certain generic prescriptions result in the dispensing of proprietary products despite the existence of generic preparations, and the pharmacist may be reimbursed for the cost of the proprietary drug which has been dispensed. Not all generic prescriptions result in the dispensing of cheaper drugs because of the methods of payment to chemists. If doctors write more generic prescriptions there will ultimately be more dispensing of generic products. Even in the case of drugs still under patent, prescribing by generic name should be encouraged. The savings achieved by generic prescribing are to some extent at the cost of the dispensing chemists. The method and scale of payments for dispensing requires urgent review. PMID:4032358

Objectives: We aimed to reliably describe the pattern of outpatient prescription of non-steroidal anti-inflammatory drugs (NSAIDs) and antibiotics (ATBs) at a central hospital in the West Bank, Palestine. Methods: This was a retrospective, cross-sectional study investigating a cohort of 2,208 prescriptions ordered by outpatient clinics and the emergency room over one year in Beit Jala Hospital in Bethlehem, West Bank. The orders were analysed for the rate and types of NSAIDs and ATBs utilised, and the appropriateness of these drugs to the diagnosis. Results: Of the total prescriptions, 410 contained NSAIDs (18.6%), including diclofenac (40.2%), low dose aspirin (23.9%), ibuprofen (17.8%) and indomethacin (15.1%). A minority of these prescriptions contained a combination of these agents (2.5%). Only one prescription contained cyclooxyeganse-2 inhibitors (0.2%). The appropriateness of NSAID use to the diagnosis was as follows: appropriate (58.3%), inappropriate (14.4%) and difficult to tell (27.3%). The rate of ATB use was 30.3% (669 prescriptions). The ATBs prescribed were amoxicillin (23.3%), augmentin (14.3%), quinolones (12.7%), first and second generation cephalosporins (9.4% and 12.7%, respectively) and macrolides (7.2%). ATB combinations were identified in 9.4%, with the most common being second-generation cephalopsorins and metronidazole (4.3%). Regarding the appropriateness of prescribing ATBs according to the diagnosis, it was appropriate in 44.8%, inappropriate in 20.6% and difficult to tell in 34.6% of the prescriptions. Conclusion: These findings revealed a relatively large number and inappropriate utilisation of ATBs and NSAIDs. An interventional programme needs to be adopted to reinforce physicians’ knowledge of the rational prescription of these agents. PMID:24273668

High antibiotic prescribing and antimicrobial resistance in patients attending primary care have been reported in South America. Very few interventions targeting general practitioners (GPs) to decrease inappropriate antibiotic prescribing have been investigated in this region. This study assessed the effectiveness of online feedback on reducing antibiotic prescribing in patients with suspected respiratory tract infections (RTIs) attending primary care. The aim was to reduce antibiotic prescribing in patients with acute bronchitis and acute otitis media. Both are RTIs for which antibiotics have a very limited effect. A cluster randomized two-arm control trial was implemented. Healthcare centres from Bolivia, Argentina, Paraguay and Uruguay participating in the quality improvement program HAPPY AUDIT were randomly allocated to either intervention or control group. During ten consecutive weeks, GPs in the intervention group received evidence-based online feedback on the management of suspected RTIs. In patients with acute bronchitis, the intervention reduced the antibiotic prescribing rate from 71.6% to 56% (control group from 61.2% to 52%). In patients with acute otitis media, the intervention reduced the antibiotic prescribing from 94.8% to 86.2% (no change in the control group). In all RTIs, the intervention reduced antibiotic prescribing rate from 37.4% to 28.1% (control group from 29% to 27.2%). Online evidence-based feedback is effective for reducing antibiotic prescribing in patients with RTIs attending primary care in South America. PMID:29240687

Psychiatric Prescribers' Experiences With Doctor Shoppers.

Doctor shopping is a primary method of prescription medication diversion. After opioids, benzodiazepines and stimulants are the next most common prescription medications used nonmedically. Studies have shown that patients who engage in doctor shopping find it fun, exciting, and easy to do. There is a lack of research on the prescriber's perspective on the phenomenon of doctor shopping. This study investigates the experiences of prescribers in psychiatry with patients who engage in doctor shopping. Fifteen prescribers including psychiatrists and psychiatric nurse practitioners working in outpatient psychiatry were interviewed to elicit detailed information about their experiences with patients who engage in doctor shopping. Themes found throughout the interview were that psychiatric prescribers' experience with patients who engage in doctor shopping includes (a) detecting red flags, (b) negative emotional responding, (c) addressing the patient and the problem, and (d) inconsistently implementing precautions. When red flags were detected when prescribing controlled drugs, prescribers in psychiatry experienced both their own negative emotional responses such as disappointment and resentment as well as the negative emotions of the patients such as anger and other extreme emotional responses. Psychiatric prescribers responded to patient's doctor shopping in a variety of ways such as changing their practice, discharging the patients or taking steps to not accept certain patients identified as being at risk for doctor shopping, as well as by talking to the patient and trying to offer them help. Despite experiencing doctor shopping, the prescribers inconsistently implemented precautionary measures such as checking prescription drug monitoring programs. © The Author(s) 2015.

Objectives To assess whether prospective, observational study procedures, including questionnaires and audio recording, are associated with different patterns of physician diagnostic decision making and antibiotic prescribing. Data Sources/Setting (1) Survey data from a prospective observational study of treatment patterns for children with acute upper respiratory illnesses (10/96–3/97) and (2) retrospective medical record abstraction data of nonobserved encounters for the same problems occurring during (10/96–3/97) and one year after (10/97–3/98) the observational study period. Ten pediatricians in two community practices were studied. Study Design Patterns of diagnoses recorded in the medical record and antibiotics ordered for visits occurring outside of the observational study (same time period and one year later) were compared with the pattern of diagnoses and antibiotics ordered during the observational study. Data Collection/Extraction Methods For the observational study (10/96–2/97), diagnosis and treatment choices were obtained from questionnaires completed by physicians immediately following the visit. For the nonstudy encounters (10/96–3/97 and 10/97–3/98), data were abstracted from medical records one year after the observational study was completed. Principal Findings The proportion of viral cases in which an antibiotic was prescribed was 29 percentage points lower for the observational study compared to the retrospective analysis (p <.05). In one of two study sites, the proportion of cases assigned a bacterial diagnosis was 29 percentage points lower in the observational study period compared to the retrospective study (p <.05). Conclusions Observational study procedures including questionnaires and audio recording can affect antibiotic prescribing behavior. Future observational studies aimed at examining the frequency of inappropriate antibiotic prescribing should measure and adjust for the Hawthorne effect; without such adjustments, the

The incorporation of medication indications into the prescribing process to improve patient safety is discussed. Currently, most prescriptions lack a key piece of information needed for safe medication use: the patient-specific drug indication. Integrating indications could pave the way for safer prescribing in multiple ways, including avoiding look-alike/sound-alike errors, facilitating selection of drugs of choice, aiding in communication among the healthcare team, bolstering patient understanding and adherence, and organizing medication lists to facilitate medication reconciliation. Although strongly supported by pharmacists, multiple prior attempts to encourage prescribers to include the indication on prescriptions have not been successful. We convened 6 expert panels to consult high-level stakeholders on system design considerations and requirements necessary for building and implementing an indications-based computerized prescriber order-entry (CPOE) system. We summarize our findings from the 6 expert stakeholder panels, including rationale, literature findings, potential benefits, and challenges of incorporating indications into the prescribing process. Based on this stakeholder input, design requirements for a new CPOE interface and workflow have been identified. The emergence of universal electronic prescribing and content knowledge vendors has laid the groundwork for incorporating indications into the CPOE prescribing process. As medication prescribing moves in the direction of inclusion of the indication, it is imperative to design CPOE systems to efficiently and effectively incorporate indications into prescriber workflows and optimize ways this can best be accomplished.

The objective of our study is to evaluate the association between Ohio's April 2012 emergency physician guidelines aimed at reducing inappropriate opioid prescribing and the number and type of opioid prescriptions dispensed by emergency physicians. We used Ohio's prescription drug monitoring program data from January 1, 2010, to December 31, 2014, and included the 5 most commonly prescribed opioids (hydrocodone, oxycodone, tramadol, codeine, and hydromorphone). The primary outcome was the monthly statewide prescription total of opioids written by emergency physicians in Ohio. We used an interrupted time series analysis to compare pre- and postguideline level and trend in number of opioid prescriptions dispensed by emergency physicians per month, number of prescriptions stratified by 5 commonly prescribed opioids, and number of prescriptions for greater than 3 days' supply of opioids. Beginning in January 2010, the number of prescriptions dispensed by all emergency physicians in Ohio decreased by 0.3% per month (95% confidence interval [CI] -0.49% to -0.15%). The implementation of the guidelines in April 2012 was associated with a 12% reduction (95% CI -17.7% to -6.3%) in the level of statewide total prescriptions per month and an additional decline of 0.9% (95% CI -1.1% to -0.7%) in trend relative to the preguideline trend. The estimated effect of the guidelines on total monthly prescriptions greater than a 3-day supply was an 11.2% reduction in level (95% CI -18.8% to -3.6%) and an additional 0.9% (95% CI -1.3% to -0.5%) decline in trend per month after the guidelines. Guidelines were also associated with a reduction in prescribing for each of the 5 individual opioids, with various effect. In Ohio, emergency physician opioid prescribing guidelines were associated with a decrease in the quantity of opioid prescriptions written by emergency physicians. Although introduction of the guidelines occurred in parallel with other opioid-related interventions, our

Gender-specific attitudes and communication styles are known to influence both the content and outcome of medical visits. Therefore, gender-specific differences in response to cost containment may also occur. The purpose of this study was to assess the effect of physician gender on changes in prescribing patterns of angiotensin-converting enzyme (ACE) inhibitors after the implementation of reference pricing for prescription drugs in British Columbia, Canada. Reference pricing is a cost-sharing policy by which use of high-priced medication requires out-of-pocket payment of the price difference between the cost-sharing drug and a lower-cost drug within the same class. In British Columbia, reference pricing for ACE inhibitors was introduced on January 1, 1997. Analysis was carried out on linked pharmacy and medical service claims data on 927 female and 2922 male physicians treating 47,680 Pharmacare Plan A enrollees who were aged >-65 years and were prescribed a high-priced ACE inhibitors before the implementation of reference pricing. Female physicians (24.1% of all physicians) were younger, treated more female patients, had patients with fewer chronic illnesses, and worked more often as general practitioners than did male physicians. The patients of female physicians were more likely to receive a written physician-requested exemption from copayment, according to a multivariate logistic regression analysis (odds ratio [OR], 1.25; 95% CI, 1.04-1.50). Data suggested that patients of female physicians were more likely to stop antihypertensive drug therapy (OR, 1.43; 95% CI, 0.96-2.13); however, this was independent of the new copayment policy. The results provide empirical evidence that physician gender is associated with slightly different patient management strategies regarding physician-requested exemptions after the start of a new drug cost-sharing policy. However, these differences are unlikely to have meaningful clinical or economic consequences.

Antimicrobial stewardship (AMS) programmes have been developed with the intention of reducing inappropriate and unnecessary use of antimicrobials, while improving the quality of patient care and locally helping prevent the development of antimicrobial resistance. An important aspect of AMS programmes is the qualitative assessment of prescribing through antimicrobial prescribing surveys (APS), which are able to provide information about the prescribing behaviour within institutions. Owing to lack of standardization of audit tools and the resources required, qualitative methods for the assessment of antimicrobial use are not often performed. The aim of this study was to design an audit tool that was appropriate for use in all Australian hospitals, suited to local user requirements and included an assessment of the overall appropriateness of the prescription. In November 2011, a pilot APS was conducted across 32 hospitals to assess the usability and generalizability of a newly designed audit tool. Following participant feedback, this tool was revised to reflect the requirements of the respondents. A second pilot study was then performed in November 2012 across 85 hospitals. These surveys identified several areas that can be targets for quality improvement at a national level, including: documentation of indication; surgical prophylaxis prescribed for >24 h; compliance with prescribing guidelines; and the appropriateness of the prescription. By involving the end users in the design and evaluation, we have been able to provide a practical and relevant APS tool for quantitative and qualitative data collection in a wide range of Australian hospital settings. © The Author 2015.

Drug interactions are a leading cause of morbidity and mortality. Methadone and buprenorphine are frequently prescribed for the treatment of opioid addiction. Patients needing treatment with these medications often have co-occurring medical and mental illnesses that require medication treatment. The abuse of illicit substances is also common in opioid-addicted individuals. These clinical realities place patients being treated with methadone and buprenorphine at risk for potentially toxic drug interactions. A substantial literature has accumulated on drug interactions between either methadone or buprenorphine with other medications when ingested concomitantly by humans. This review summarizes current literature in this area.

Advances in understanding and treatment of feline inappropriate elimination.

PubMed

Herron, Meghan E

2010-11-01

Feline inappropriate elimination is the number one behavioral reason for relinquishment of cats to shelters and has historically been the most commonly reported feline problem addressed by behavior professionals. Veterinarians are hence challenged to uncover the underlying motivation for this behavior so that an accurate diagnosis can be made and an effective treatment plan implemented. Before a behavioral diagnosis can be made, underlying medical disease must be addressed, making a comprehensive physical evaluation imperative. After all medical issues have been addressed, a behavior diagnoses list is made based on detailed historical information obtained from the cat owner. A distinction is first established between marking and inappropriate toileting, according to elimination postures described by the owner and the social relevance of the sites of inappropriate eliminations. Next, inadequacies of the litter box management are identified and subsequent aversions and preferences, including litter box aversion, substrate aversion, location aversion, substrate preference, and location preference, can be diagnosed. The practitioner should be cognizant of the fact that anxiety from the environment and social conflict may play a major role in both marking and inappropriate toileting behaviors. Once both the medical and behavioral diagnoses are established, a treatment plan catered to the individual cat, owner, and household environment can be formulated. This should include acceptable forms of marking when indicated, appropriate litter box management and hygiene, reduction of environmental stressors, including resolution of social conflict in multicat households, proper treatment and restricted access to soiled areas, pheromone application, and, when indicated, anxiolytic drug therapy.

Several studies of inappropriate (in the sense of the AEP) hospital days highlighted associations between two factors (rate of inappropriateness and reasons for inappropriateness, rate of inappropriateness and appropriate setting of care,..). The aim of this communication is to present a study on real associations, at constant factor, between five factors associated with hospital inappropriate days: medical management process, reason for inappropriateness, scheduled admission, rate of inappropriateness, length of stay. We used the European version of Appropriateness Evaluation Protocol for evaluation of inappropriate days and the French protocol ;for analysis of inappropriate days. The study set in three Parisian hospitals, four clinical departments, three specialities. 523 patients were included in the study, 5663 days were evaluated on a wide variety of pathologies: 27 Medical Management Processes. Results show that there are real associations (elimination of transitive associations) between five factors : medical management process and discharge processes, reason for inappropriateness, scheduled admission, rate of inappropriate days, length of stay. Multiple Correspondence Analysis on all "groups of contiguous days related with the same reason for inappropriateness" shows five profiles of queues integrating various medical management processes.

Aims To demonstrate an epidemiological method to assess predictors of prescribing errors. Methods A retrospective case-control study, comparing prescriptions with and without errors. Results Only prescriber and drug characteristics were associated with errors. Prescriber characteristics were medical specialty (e.g. orthopaedics: OR: 3.4, 95% CI 2.1, 5.4) and prescriber status (e.g. verbal orders transcribed by nursing staff: OR: 2.5, 95% CI 1.8, 3.6). Drug characteristics were dosage form (e.g. inhalation devices: OR: 4.1, 95% CI 2.6, 6.6), therapeutic area (e.g. gastrointestinal tract: OR: 1.7, 95% CI 1.2, 2.4) and continuation of preadmission treatment (Yes: OR: 1.7, 95% CI 1.3, 2.3). Conclusions Other hospitals could use our epidemiological framework to identify their own error predictors. Our findings suggest a focus on specific prescribers, dosage forms and therapeutic areas. We also found that prescriptions originating from general practitioners involved errors and therefore, these should be checked when patients are hospitalized. PMID:11874397

Objectives To describe the incidence of recorded mental illness and challenging behaviour in people with intellectual disability in UK primary care and to explore the prescription of psychotropic drugs in this group. Design Cohort study. Setting 571 general practices contributing data to The Health Improvement Network clinical database. Participants 33 016 adults (58% male) with intellectual disability who contributed 211 793 person years’ data. Main outcome measures Existing and new records of mental illness, challenging behaviour, and psychotropic drug prescription. Results 21% (7065) of the cohort had a record of mental illness at study entry, 25% (8300) had a record of challenging behaviour, and 49% (16 242) had a record of prescription of psychotropic drugs. During follow-up, the rate of new cases of mental illness in people without a history at cohort entry was 262 (95% confidence interval 254 to 271) per 10 000 person years and the rate of challenging behaviour was 239 (231 to 247) per 10 000 person years. The rate of new psychotropic drug prescription in those without a previous history of psychotropic drug treatment was 518 (503 to 533) per 10 000 person years. Rates of new recording of severe mental illness declined by 5% (95% confidence interval 3% to 7%) per year (P<0.001), and new prescriptions of antipsychotics declined by 4% (3% to 5%) per year P<0.001) between 1999 and 2013. New prescriptions of mood stabilisers also decreased significantly. The rate of new antipsychotic prescribing was significantly higher in people with challenging behaviour (incidence rate ratio 2.08, 95% confidence interval 1.90 to 2.27; P<0.001), autism (1.79, 1.56 to 2.04; P<0.001), and dementia (1.42, 1.12 to 1.81; P<0.003) and in those of older age, after control for other sociodemographic factors and comorbidity. Conclusions The proportion of people with intellectual disability who have been treated with psychotropic drugs far exceeds the proportion with

To assess nurse practitioners' interactions with pharmaceutical industry promotional activities and their perception of information reliability and self-reported prescribing behaviors. Self-administered online survey. A nationally randomized sample of nurse practitioner prescribers was surveyed. Eligibility criteria included current clinical practice and licensure to prescribe medications in their state of practice. A total of 263 responses were analyzed. Almost all respondents (96%) reported regular contact with pharmaceutical sales representatives, and most (71%) reported receiving information on new drugs directly from pharmaceutical sales representatives some or most of the time. A large portion (66%) dispensed drug samples regularly to their patients, and 73% believed that samples were somewhat or very helpful in learning about new drugs. Eighty-one percent of respondents thought that it was ethically acceptable to give out samples to anyone, and 90% believed that it was acceptable to attend lunch and dinner events sponsored by the pharmaceutical industry. Almost half (48%) stated that they were more likely to prescribe a drug that was highlighted during a lunch or dinner event. Most respondents stated that it was ethically acceptable for speakers to be paid by industry. Nurse practitioner prescribers had extensive contact with pharmaceutical industry promotional activities such as pharmaceutical representative contact, receipt of drug samples, and regular attendance at industry-sponsored meal events and continuing education programs. They reported that industry interface with nurse practitioner prescribers in the form of sponsored meals, education events, and paid speakers was ethically acceptable.

There is evidence of inappropriate medication use, causing unnecessary costs for health systems, particularly those with limited resources. Overprescription is commonly reported and can lead to antibiotic resistance. Prescribing patterns differ between countries; little is known about paediatric prescribing practices in Africa. To investigate prescribing practices in children in The Gambia, West Africa. A retrospective survey of prescribing practices in children under 5 years of age based on WHO protocol DAP/93.1 was conducted. Twenty government-run health centres across all six regions in The Gambia were assessed. The first 10 encounters each month in 2010 were recorded. For each encounter, patient demographics, diagnoses and medications were recorded as per protocol. Two thousand and four hundred patient encounters were included. The mean number of medications per encounter was 2.2 (median 2.0, IQR 2.0-3.0). Across different geographical regions within The Gambia antibiotics were prescribed in 63.4% (IQR 62.8-65.8%) and micronutrients in 21.7% (IQR 15.3-27.1%) of patient encounters. There was evidence of high antibiotic prescription in children with cough and coryzal symptoms (54.5%; IQR 35.8-59.0%) and simple diarrhoea without dehydration (44.8%; IQR 36.7-61.3%). 74.8% (IQR 71.8-76.1%) of medications were prescribed generically. The study showed an overprescription of antibiotics and substantial usage of micronutrients despite a lack of international evidence-based guidelines. Cost-effective interventions to improve prescribing practices are called for and more studies with a focus on rational prescribing in paediatrics in low-income settings are urgently required to fill the gap in current knowledge.

To assess the impact of a closed-loop electronic prescribing, automated dispensing, barcode patient identification and electronic medication administration record (EMAR) system on prescribing and administration errors, confirmation of patient identity before administration, and staff time. Before-and-after study in a surgical ward of a teaching hospital, involving patients and staff of that ward. Closed-loop electronic prescribing, automated dispensing, barcode patient identification and EMAR system. Percentage of new medication orders with a prescribing error, percentage of doses with medication administration errors (MAEs) and percentage given without checking patient identity. Time spent prescribing and providing a ward pharmacy service. Nursing time on medication tasks. Prescribing errors were identified in 3.8% of 2450 medication orders pre-intervention and 2.0% of 2353 orders afterwards (p<0.001; chi(2) test). MAEs occurred in 7.0% of 1473 non-intravenous doses pre-intervention and 4.3% of 1139 afterwards (p = 0.005; chi(2) test). Patient identity was not checked for 82.6% of 1344 doses pre-intervention and 18.9% of 1291 afterwards (p<0.001; chi(2) test). Medical staff required 15 s to prescribe a regular inpatient drug pre-intervention and 39 s afterwards (p = 0.03; t test). Time spent providing a ward pharmacy service increased from 68 min to 98 min each weekday (p = 0.001; t test); 22% of drug charts were unavailable pre-intervention. Time per drug administration round decreased from 50 min to 40 min (p = 0.006; t test); nursing time on medication tasks outside of drug rounds increased from 21.1% to 28.7% (p = 0.006; chi(2) test). A closed-loop electronic prescribing, dispensing and barcode patient identification system reduced prescribing errors and MAEs, and increased confirmation of patient identity before administration. Time spent on medication-related tasks increased.

Use of non-prescribed drugs during treatment for opiate addiction reduces treatment success, creating a need for effective interventions. This review aimed to assess the efficacy of contingency management, a behavioural treatment that uses rewards to encourage desired behaviours, for treating non-prescribed drug use during opiate addiction treatment. A systematic search of the databases Embase, PsychInfo, PsychArticles and Medline from inception to March 2015 was performed. Random effects meta-analysis tested the use of contingency management to treat the use of drugs during opiate addiction treatment, using either longest duration of abstinence (LDA) or percentage of negative samples (PNS). Random effects moderator analyses were performed for six potential moderators: drug targeted for intervention, decade in which the study was carried out, study quality, intervention duration, type of reinforcer, and form of opiate treatment. The search returned 3860 papers; 22 studies met inclusion criteria and were meta-analysed. Follow-up data was only available for three studies, so all analyses used end of treatment data. Contingency management performed significantly better than control in reducing drug use measured using LDA (d=0.57, 95% CI: 0.42-0.72) or PNS (d=0.41) (95% CI: 0.28-0.54). This was true for all drugs other than opiates. The only significant moderator was drug targeted (LDA: Q=10.75, p=0.03). Contingency management appears to be efficacious for treating most drug use during treatment for opiate addiction. Further research is required to ascertain the full effects of moderating variables, and longer term effects. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

Inappropriate antibiotic prescribing for nonbacterial infections leads to increases in the costs of care, antibiotic resistance among bacteria, and adverse drug events. Acute respiratory infections (ARIs) are the most common reason for inappropriate antibiotic use. Most prior efforts to decrease inappropriate antibiotic prescribing for ARIs (e.g., educational or informational interventions) have relied on the implicit assumption that clinicians inappropriately prescribe antibiotics because they are unaware of guideline recommendations for ARIs. If lack of guideline awareness is not the reason for inappropriate prescribing, educational interventions may have limited impact on prescribing rates. Instead, interventions that apply social psychological and behavioral economic principles may be more effective in deterring inappropriate antibiotic prescribing for ARIs by well-informed clinicians. The Application of Behavioral Economics to Improve the Treatment of Acute Respiratory Infections (BEARI) Trial is a multisite, cluster-randomized controlled trial with practice as the unit of randomization. The primary aim is to test the ability of three interventions based on behavioral economic principles to reduce the rate of inappropriate antibiotic prescribing for ARIs. We randomized practices in a 2 × 2 × 2 factorial design to receive up to three interventions for non-antibiotic-appropriate diagnoses: 1) Accountable Justifications: When prescribing an antibiotic for an ARI, clinicians are prompted to record an explicit justification that appears in the patient electronic health record; 2) Suggested Alternatives: Through computerized clinical decision support, clinicians prescribing an antibiotic for an ARI receive a list of non-antibiotic treatment choices (including prescription options) prior to completing the antibiotic prescription; and 3) Peer Comparison: Each provider's rate of inappropriate antibiotic prescribing relative to top-performing peers is reported back to

The records of 430 patients taking antithrombotic drugs who underwent emergency endoscopy for UGIB in Saga Medical School Hospital between 2002 and 2011 were studied. We also compared the characteristics of our cohort of 11,919 patients prescribed antithrombotic drugs in our hospital between 2002 and 2011. UBGI patients of variceal bleeding were not included in this study. 186 patients presented with UGIB in the first period (2002-2006) and 244 in the second period (2007-2011). The proportion of patients infected with Helicobacter pylori was lower in the second period, while the proportion taking antithrombotic drugs rose significantly. Peptic ulcer disease was responsible for the majority of bleeding episodes; however, bleeding from other sources is increasing. In the whole cohort, the risk of UGIB was 1.08%; however, of the 31.8% who also took an acid-secretion inhibitor only 18 (0.28%) developed bleeding. In contrast, 102 (1.87%) of those not taking an acid-secretion inhibitor developed UGIB, a statistically significant difference. Risk of UGIB in Japanese patients taking antithrombotics was 1.01% and the incidence is increasing. Acid-secretion inhibitors reduced the risk of antithrombotic drug-related UGIB.

Inappropriate prescribing of antibiotics by health care professionals is a worldwide concern. This study evaluated the knowledge and practices of dental practitioners in the city of Shiraz, Islamic Republic of Iran regarding their therapeutic use of antibiotics for patients with dentoalveolar infections. Of 219 (48.6%) dentists responding to the questionnaire more than 40% would prescribe antibiotics for localized fluctuant swelling and for problems for which antibiotics are not required according to good practice guidelines (acute pulpitis, chronic apical infection, periodontal abscess, chronic gingivitis, chronic periodontitis, pericoronitis and dry socket). A majority correctly prescribed antibiotics for acute periapical infection (77.2%), cellulitis (75.3%) and acute ulcerated gingivitis (63.0%). Amoxicillin was the most frequently prescribed antibiotic for all clinical conditions but there was a wide variation in dosage, frequency and duration for all antibiotics used. Guidelines on rational antibiotic use are needed for dental practitioners in the Islamic Republic of Iran.

High risk prescribing in older adults: prevalence, clinical and economic implications and potential for intervention at the population level

PubMed Central

2013-01-01

Background High risk prescribing can compromise independent wellbeing and quality of life in older adults. The aims of this project are to determine the prevalence, risk factors, clinical consequences, and costs of high risk prescribing, and to assess the impact of interventions on high risk prescribing in older people. Methods The proposed project will utilise data from the 45 and Up Study, a large scale cohort of 267,153 men and women aged 45 and over recruited during 2006–2009 from the state of New South Wales, Australia linked to a range of administrative health datasets. High risk prescribing will be assessed using three indicators: polypharmacy (use of five or more medicines); Beers Criteria (an explicit measure of potentially inappropriate medication use); and Drug Burden Index (a pharmacologic dose-dependent measure of cumulative exposure to anticholinergic and sedative medicines). Individual risk factors from the 45 and Up Study questionnaire, and health system characteristics from health datasets that are associated with the likelihood of high risk prescribing will be identified. The main outcome measures will include hospitalisation (first admission to hospital, total days in hospital, cause-specific hospitalisation); admission to institutionalised care; all-cause mortality, and, where possible, cause-specific mortality. Economic costs to the health care system and implications of high risk prescribing will be also investigated. In addition, changes in high risk prescribing will be evaluated in relation to certain routine medicines-related interventions. The statistical analysis will be conducted using standard pharmaco-epidemiological methods including descriptive analysis, univariate and multivariate regression analysis, controlling for relevant confounding factors, using a number of different approaches. Discussion The availability of large-scale data is useful to identify opportunities for improving prescribing, and health in older adults. The size

Inappropriate nonsteroidal anti-inflammatory drugs (NSAIDs) therapy is a common cause of actual and potential adverse effects, such as bleeding and gastrointestinal ulceration, which exacerbates the patient's medical condition and might even be life threatening. We aimed to evaluate and analyze the prescription pattern of NSAIDs in Northeastern Iranian population and also provide suggestions for a more rational prescription behavior for such drugs. In this cross-sectional retrospective study, pattern of 1-year prescriptions was inspected based on 9.3 million prescriptions from two insurance companies. Type of NSAIDs, all dispensed doses and the number of NSAIDs ordered per prescription, and the route of administration for each patient were extracted from the databases. The prescription pattern of NSAIDs was analyzed seasonally. Out of 9,303,585 prescriptions, 19.3% contained at least one NSAID. Diclofenac was the most commonly prescribed NSAID (49.21%). At least two NSAIDs were simultaneously prescribed in 7% of prescriptions. General practitioners prescribed NSAIDs more frequently (67%) than specialists. Orthopedic surgeons and internists more frequently prescribed NSAIDs in comparison with other physicians (6% and 4%, respectively). Gastroprotective agents (GPAs) were coprescribed to only 7.62% of prescriptions. The frequency of NSAIDs prescription was relatively high in Northeast of Iran. A significant number of prescriptions were associated with irrational prescribing in both coadministration of NSAIDs and GPAs and NSAIDs combination. A strategy must be developed and implemented for prescribing and rational use of medications, e.g., continuing medical education regarding the potential risks of NSAIDs, importance of their appropriate and rational use, and necessity of appropriate prescription writing regarding both content and indication.

State-level prescription drug monitoring programs (PDMPs) have been implemented in most states. PDMPs enable registered prescribers to obtain real-time information on patients' prescription history to reduce non-medical use of controlled drugs. This study examined whether PDMP implementation and different levels of PDMP requirements were associated with physicians' patterns of prescribing opioid analgesics for patients with non-cancer chronic pain. This is a secondary analysis study using cross-sectional national data. Patients with non-cancer chronic pain from the 2012 National Ambulatory Medical Care Survey were included (weighted N=81,018,131; unweighted N=3295). Heckman two-step selection procedure employing two logistic regressions was used to explore the associations between PDMP requirements and physicians' prescribing behaviors, controlling for physician characteristics, patient characteristics, physician-healthcare system interaction, and physician-patient relationship, guided by the Eisenberg's model of physician decision making. State PDMP implementation status and requirement levels were not associated with physician opioid prescribing for non-cancer chronic pain treatment (p's ranged 0.30-0.32). Patients with Medicare coverage were more likely to be prescribed opioid analgesics than those with private health insurance (OR=1.55, p<0.01). Hispanic patients were less likely to be prescribed opioid analgesics than non-Hispanic white patients (OR=0.61, p<0.05). Findings indicated that the effectiveness of PDMPs on physicians' opioid prescribing tendency for non-cancer chronic pain treatment could not be supported. Policy makers should be aware of the need for redesigning PDMPs regarding requirements and enforcement for prescribers and related stakeholders. Future studies also are needed to identify characteristics contributing to PDMP effectiveness in reducing non-medical use of prescription opioids. Copyright © 2017 Elsevier Ltd. All rights reserved.

Pharmaceutical prescribing and drug-drug interaction data underlie recommendations on drug combinations that should be avoided or closely monitored by prescribers. Because the number of patients taking multiple medications is increasing, a comprehensive view of prescribing patterns in patients is important to better assess real world pharmaceutical response and evaluate the potential for multi-drug interactions. We obtained self-reported prescription data from NHANES surveys between 1999 and 2010, and confirm the previously reported finding of increasing drug use in the elderly. We studied co-prescription drug trends by focusing on the 2009-2010 survey, which contains prescription data on 690 drugs used by 10,537 subjects. We found that medication profiles were unique for individuals aged 65 years or more, with ≥98 unique drug regimens encountered per 100 subjects taking 3 or more medications. When drugs were viewed by therapeutic class, it was found that the most commonly prescribed drugs were not the most commonly co-prescribed drugs for any of the 16 drug classes investigated. We cross-referenced these medication lists with drug interaction data from Drugs.com to evaluate the potential for drug interactions. The number of drug alerts rose proportionally with the number of co-prescribed medications, rising from 3.3 alerts for individuals prescribed 5 medications to 11.7 alerts for individuals prescribed 10 medications. We found 22% of elderly subjects taking both a substrate and inhibitor of a given cytochrome P450 enzyme, and 4% taking multiple inhibitors of the same enzyme simultaneously. By examining drug pairs prescribed in 0.1% of the population or more, we found low agreement between co-prescription rate and co-discussion in the literature. These data show that prescribing trends in treatment could drive a large extent of individual variability in drug response, and that current pairwise approaches to assessing drug-drug interactions may be inadequate for

Opioid analgesics and benzodiazepines are often misused in clinical practice. We determined whether implementation of a centralized prescription network offering real-time access to patient-level data on filled prescriptions (PharmaNet) reduced the number of potentially inappropriate prescriptions for opioids and benzodiazepines. We conducted a time series analysis using prescription records between Jan. 1, 1993, and Dec. 31, 1997, for residents of the province of British Columbia who were receiving social assistance or were 65 years or older. We calculated monthly percentages of filled prescriptions for an opioid or a benzodiazepine that were deemed inappropriate (those issued by a different physician and dispensed at a different pharmacy within 7 days after a filled prescription of at least 30 tablets of the same drug). Within 6 months after implementation of PharmaNet in July 1995, we observed a relative reduction in inappropriate filled prescriptions for opioids of 32.8% (95% confidence interval [CI] 31.0%-34.7%) among patients receiving social assistance; inappropriate filled prescriptions for benzodiazepines decreased by 48.6% (95% CI 43.2%-53.1%). Similar and statistically significant reductions were observed among residents 65 years or older. The implementation of a centralized prescription network was associated with a dramatic reduction in inappropriate filled prescriptions for opioids and benzodiazepines.

The United States is in the midst of an opioid epidemic. These medications continue to be used to manage pain associated with osteoarthritis, despite mounting evidence questioning the benefits. The rate at which opioids are prescribed for osteoarthritis is largely unknown. We sought to identify rates of opioid prescriptions for osteoarthritis and identify factors associated with higher rates of prescribing. We queried the Humana, Inc. administrative claims database from 2007 to 2014. Patients with osteoarthritis were identified using International Classification of Diseases 9th Revision codes and classified as having hip, knee, or any joint osteoarthritis. Claims data were reviewed to identify opioid prescriptions associated with a diagnosis of osteoarthritis. Rates of prescribing were trended over time and stratified by sex, age, and geographic region. From 2007 to 2014, 17.0% of patients with any joint osteoarthritis, 13.4% of patients with hip osteoarthritis, and 15.9% with knee osteoarthritis were prescribed an opioid for their condition. Yearly rates of prescription were fairly stable over this period. Patients in the South had the highest odds of opioid prescription, while those in the Northeast had the lowest. Patients ≤49 years old were more likely to receive a prescription than those ≥50 years old. This study provides important epidemiologic data about the use of opioids for osteoarthritis. Despite increasing evidence calling proposed benefits into question and increasing awareness of risks of opioids, prescribing rates remained stable between 2007 and 2014. This provides important baseline data as we work to combat excessive and inappropriate opioid use within the United States. Copyright © 2017 Elsevier Inc. All rights reserved.

The aim was to determine distribution and trends in the outpatient utilization of antipsychotics to evaluate the rationality of antipsychotic drug prescribing during the ten year period. The epidemiological method of descriptive and analytical observation was used. Data on drug utilization from Zagreb Municipal Pharmacy were used to calculate the number of defined daily doses (DDD) and DDD per 1000 inhabitants per day (DDD/TID) using the World Health Organization Anatomical-Therapeutic-Chemical methodology. The ratio of typical versus atypical antipsychotics served as an indicator on assessing the rationality of the utilization. Data on the use of anticholinergics in the treatment of neuroleptic side effects were also included. Outpatient utilization of antipsychotics showed a declining pattern from 14.17 in 2001 to 8.42 DDD/TID in 2010. The utilization of atypical antipsychotics increased by 60% (from 3.68 to 5.89 DDD/TID), while the utilization of typical antipsychotics decreased by 76% (from 10.49 to 2.53 DDD/TID). The drugs showing the largest increase were olanzapine (from 1.21 to 2.78 DDD/TID) and quetiapine (from 0 to 0.68 DDD/TID). The typical/atypical antipsychotic ratio changed from 1:0.4 in 2001 to 1:2.3 in 2010. A 2.3-fold decrease was recorded in the utilization of anticholinergics (from 2.05 to 0.91 DDD/TID). Total consumption of neuroleptics significantly decreased. A decrease was also recorded in the utilization of anticholinergics. Study results pointed to two favorable features, i.e. low use of typical antipsychotics and the ratio of typical and atypical antipsychotics. Implementation of the new clinical guidelines for nervous system disorders and updating of the list of reimbursable drugs with the addition of new ones contributed to the observed improvement in the prescribing patterns during the study period. Using the WHO ATC/DDD methodology and rationality indicators in the assessment of trends in the outpatient utilization of

In Pakistan, there is no mechanism to monitor the drug promotional campaign by pharmaceutical industry despite the fact that there is enough evidence that irrational pharmacotherapy is increasingly encountered even in the developed countries due to unethical practices of pharmaceutical promotion. Objectives. To audit the drug promotional claims made by the pharmaceutical companies in Pakistan. Drug promotional pamphlets and brochures containing claims for the drugs, which were circulated by the pharmaceutical representatives were collected from 122 general practitioners (GPs) from Karachi and Larkana cities of the Sindh Province. The claims were critically analyzed and audited with the help of currently available evidence in the medical literature. 345 distinct advertisements covering 182 drugs from different manufacturers were critically analyzed for information content. Sixty two out of 345 (18%) of the reviewed advertisements were adjudged to be misleading / unjustifiable, which were again classified as, exaggerated (32%), ambiguous (21%), false (26%), and controversial (21%). The primary source of information (approximately 78%) about the newly launched drugs for the GPs was found to be the pharmaceutical representatives followed by hospital doctors (5%) and colleagues (5%). Furthermore, 110 (90%) GPs were of the view that the drug promotion has definitely an influence on their prescribing pattern. Since GPs in Pakistan rate pharmaceutical companies as their primary source of information regarding drugs, it can be anticipated that inappropriate advertisement claims would lead to irrational prescribing if physicians had no any other information to follow.

Governmental oversight of prescribing medications: history of the US Food and Drug Administration and prescriptive authority.

PubMed

Plank, Linda S

2011-01-01

The evolution of drug regulation and awarding of prescriptive authority is a complex and sometimes convoluted process that can be confusing for health care providers. A review of the history of how drugs have been manufactured and dispensed helps explain why this process has been so laborious and complicated. Because the federal and state governments have the responsibility for protecting the public, most regulations have been passed with the intentions of ensuring consumer safety. The current system of laws and regulations is the result of many years of using the legal system to correct drug marketing that had adverse health consequences. Government oversight will continue as prescribing medications transitions to an electronic form and as health care professionals in addition to physicians seek to gain prescriptive authority. © 2011 by the American College of Nurse-Midwives.

Antimicrobial resistance is a worldwide threat to public health. Acute respiratory tract infections are the main reason for antibiotic prescribing in the Spanish paediatric population. The aim of the study was to describe the frequency of antibiotic prescription and their pattern of use in acute respiratory tract infections diagnosed in children in Primary Care in Aragón (Spain). A study was conducted over a 1-year period on children between 0 and 14 years-old, recording all episodes of acute otitis, acute pharyngotonsillitis, non-specific upper respiratory infection, and acute bronchitis. The proportion of episodes within each diagnosis receiving an antibiotic prescription was calculated, and the prescribing pattern was determined. Half (50%) of the children in Aragón were diagnosed with a respiratory tract infection during the study period. Non-specific upper respiratory infection was the most frequent diagnosis. An antibiotic was prescribed in 75% of pharyngotonsillitis episodes, 72% of otitis, 27% of bronchitis, and 16% of non-specific upper respiratory infections. Broad spectrum antibiotics, mainly amoxicillin and amoxicillin-clavulanic, were predominantly prescribed. Antibiotic prescribing in respiratory tract infections in children was generally high, and the choice of antibiotics was probably inappropriate in a high percentage of cases. Therefore an improvement in antibiotic prescribing in children appears to be needed. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U. All rights reserved.

Potentially Inappropriate Prescriptions (PIP) is drug treatment, which in general, at the group level for a median/mean patient, can be considered unfavorable meaning that the risks commonly may outweigh the benefits. This MiniReview reports and discusses the main findings in a large cluster-randomized educational intervention in Norwegian general practice, aimed at reducing the prevalence of PIPs to patients ≥ 70 years (The Rx-PAD study). Targets for the intervention were general practitioners (GPs) in continuing medical education (CME) groups receiving educational outreach visits (i.e., peer academic detailing). A Delphi consensus process, with a panel of medical experts was undertaken to elaborate a list of explicit criteria defining PIPs for patients ≥ 70 years in general practice. Agreement was achieved for 36 explicit PIP criteria, the so-called Norwegian General Practice (NorGeP) criteria. Using a selection (n = 24) of these criteria during a one-year baseline period on the prescribing practice of 454 GPs (i.e., those enrolled to participate in the intervention trial), we found a prevalence rate of 24.7 PIPs per 100 patients ≥70 years per year. In the Rx-PAD study, 449 GPs completed an educational intervention (96.6% of the included GPs), 250 in the intervention group and 199 in the control arm. Following the intervention, PIPs were reduced by 13% (95% CI 8.6 - 17.3), and the number of patients who were no longer exposed to one or more PIPs was reduced by 1173 (8.1%). The GPs who responded most strongly to the educational intervention were the oldest GPs (57-68 years) and these were the GPs with the highest prevalence of PIPs at baseline before the intervention.

Uganda began implementation of a structural adjustment programme (SAP) in July 1994 in order to improve social services. The decentralization of health services administration to district level was intended to improve the quality of health services and pharmaceutical supplies in the hospitals, with resultant increase in the level of utilization of health facilities. This study evaluated the impact of the decentralization policy on health facility utilization; availability of essential drugs, and prescribing patterns for acute respiratory infections (ARI), diarrhoea, and malaria in two district hospitals in Uganda. Mixed method evaluation design, involving both quantitative and qualitative methods. Time series analyses of data from utilization, pharmacy stock, and prescription records before and after the policy change. Key informant interviews and focus group discussions to obtain information on perceptions and attitude of stakeholders on the process of the policy implementation. STUDY SETTING AND POPULATION: The study was conducted in two district hospitals in northern Uganda. A total of seven years of utilization and pharmacy stock data including 5040 patient records from the hospitals were analysed retrospectively. In-depth interviews were conducted among 11 politicians from each district; 100 open-ended questionnaires were administered to patients in each hospital; 86 health care workers were interviewed using semi-structured questionnaires; and focus group discussions were conducted with 23 health care providers. Facility utilization was evaluated by average monthly attendance in the outpatient department and paediatric ward admissions. Availability was assessed as average number of drugs per month. Prescribing indicator outcomes included: for malaria, percent chloroquine tablets and percent chloroquine injection; for ARI, percent receiving antibiotics or injections; for diarrhoea, use of oral rehydration salts (ORS), antidiarrhoeal mixtures, and antibiotics

Objectives To assess the impact of a closed‐loop electronic prescribing, automated dispensing, barcode patient identification and electronic medication administration record (EMAR) system on prescribing and administration errors, confirmation of patient identity before administration, and staff time. Design, setting and participants Before‐and‐after study in a surgical ward of a teaching hospital, involving patients and staff of that ward. Intervention Closed‐loop electronic prescribing, automated dispensing, barcode patient identification and EMAR system. Main outcome measures Percentage of new medication orders with a prescribing error, percentage of doses with medication administration errors (MAEs) and percentage given without checking patient identity. Time spent prescribing and providing a ward pharmacy service. Nursing time on medication tasks. Results Prescribing errors were identified in 3.8% of 2450 medication orders pre‐intervention and 2.0% of 2353 orders afterwards (p<0.001; χ2 test). MAEs occurred in 7.0% of 1473 non‐intravenous doses pre‐intervention and 4.3% of 1139 afterwards (p = 0.005; χ2 test). Patient identity was not checked for 82.6% of 1344 doses pre‐intervention and 18.9% of 1291 afterwards (p<0.001; χ2 test). Medical staff required 15 s to prescribe a regular inpatient drug pre‐intervention and 39 s afterwards (p = 0.03; t test). Time spent providing a ward pharmacy service increased from 68 min to 98 min each weekday (p = 0.001; t test); 22% of drug charts were unavailable pre‐intervention. Time per drug administration round decreased from 50 min to 40 min (p = 0.006; t test); nursing time on medication tasks outside of drug rounds increased from 21.1% to 28.7% (p = 0.006; χ2 test). Conclusions A closed‐loop electronic prescribing, dispensing and barcode patient identification system reduced prescribing errors and MAEs, and increased confirmation of patient identity before

There is limited data regarding the relationship between age and inappropriate therapy among patients with an implantable cardioverter-defibrillator (ICD) and resynchronization therapy. We aimed to investigate this relationship and the effect of ICD programming on inappropriate therapy by age. In the Multicenter Automatic Defibrillator Implantation Trial-Reduce Inappropriate Therapy (MADIT-RIT) 1500 patients were randomized to 3 ICD programming arms: (A) conventional with ventricular tachycardia (VT) therapy ≥170; (B) high-rate cutoff with VT therapy ≥200, and (C) prolonged 60-second delay for VT therapy ≥170. We investigated the relationship between age, the risk of inappropriate ICD therapy (including antitachycardia pacing [ATP] or shock), and ICD programming. Cumulative incidence function Kaplan-Meier graphs showed an inverse relationship between increasing quartiles of age (Q1: ≤55, Q2: 56-64, Q3: 65-71, and Q4: ≥72 years) and the risk for inappropriate therapy. Multivariate analyses showed that each increasing decade of life was associated with 34% (P < .001), 27% (P < .001), and 26% (P < .001) reduction in the risk of inappropriate shock, inappropriate ATP, and any inappropriate therapy, respectively. Treatment arms B and C as compared with arm A were associated with a significant reduction in the risk of inappropriate therapies across all age quartiles (P < .001 for all). Among patients with a primary prevention indication for an ICD, there is an inverse relationship between age and inappropriate ICD therapy. Innovative ICD programming of high-rate cutoff or prolonged delay for VT therapy is associated with significant reductions in inappropriate therapy among all age groups.

Raisch, D W

1990-04-01

The purpose of this literature review is to develop a model of methods to be used to influence prescribing. Four bodies of literature were identified as being important for developing the model: (1) Theoretical prescribing models furnish information concerning factors that affect prescribing and how prescribing decisions are made. (2) Theories of persuasion provide insight into important components of educational communications. (3) Research articles of programs to improve prescribing identify types of programs that have been found to be successful. (4) Theories of human inference describe how judgments are formulated and identify errors in judgment that can play a role in prescribing. This review is presented in two parts. This article reviews prescribing models, theories of persuasion, studies of administrative programs to control prescribing, and sub-optimally designed studies of educational efforts to influence drug prescribing.

In developing countries, inappropriate, inefficient and ineffective use of pharmaceuticals have resulted into the poor health and medical cares for the community people. For improving the situation, various interventions have been tested and proved effective in different settings. In Nepal also, various strategies have been tested and found effective to improve the prescribing and dispensing practices. This paper has examined the process and results of different studies. The educational intervention, the training has not been effective in improving the prescribing practices but has limited effect on dispensing practices in the public sector. However, it becomes effective in improving prescribing practices if combined with a managerial intervention e.g. peer-group discussion. In private sector, training alone is effective in changing the drug recommendation practices of retailers. But none of interventions have been found to be effective in improving dispensing practices. After examining the effectiveness of different interventions, training combined with peer-group discussion is recommended for piloting in all Primary Health Care (PHC) outlets of a district to improve the prescribing practices. For improving the dispensing practices in both public and private sector, additional studies have to be carried out using different strategies.

To determine the prescribing activity of different staff groups within intensive care unit (ICU) and combined high dependency unit (HDU), namely trainee and consultant medical staff and advanced nurse practitioners in critical care (ANPCC); to determine the number and type of prescription errors; to compare error rates between prescribing groups and to raise awareness of prescribing activity within critical care. The introduction of government legislation has led to the development of non-medical prescribing roles in acute care. This has facilitated an opportunity for the ANPCC working in critical care to develop a prescribing role. The audit was performed over 7 days (Monday-Sunday), on rolling days over a 7-week period in September and October 2011 in three ICUs. All drug entries made on the ICU prescription by the three groups, trainee medical staff, ANPCCs and consultant anaesthetists, were audited once for errors. Data were collected by reviewing all drug entries for errors namely, patient data, drug dose, concentration, rate and frequency, legibility and prescriber signature. A paper data collection tool was used initially; data was later entered onto a Microsoft Access data base. A total of 1418 drug entries were audited from 77 patient prescription Cardexes. Error rates were reported as, 40 errors in 1418 prescriptions (2·8%): ANPCC errors, n = 2 in 388 prescriptions (0·6%); trainee medical staff errors, n = 33 in 984 (3·4%); consultant errors, n = 5 in 73 (6·8%). The error rates were significantly different for different prescribing groups (p < 0·01). This audit shows that prescribing error rates were low (2·8%). Having the lowest error rate, the nurse practitioners are at least as effective as other prescribing groups within this audit, in terms of errors only, in prescribing diligence. National data is required in order to benchmark independent nurse prescribing practice in critical care. These findings could be used to inform research and role

A controlled cross-over study in 12 Victorian public hospitals was performed to examine the power of marketing techniques in influencing prescribing. The targeted prescribing behaviour was the use of antibiotic prophylaxis in surgery, and the criteria for judging the appropriateness of therapy were its duration and timing, as are detailed in the fourth edition of the booklet Antibiotic guidelines. The first intervention was mounted in 1985 in six hospitals (two metropolitan teaching hospitals, one suburban general hospital and three rural hospitals), and six matched hospitals acted as control hospitals. One year later, the intervention was mounted in the six hospitals that previously had been the control hospitals. The interventional campaign consisted of material that was similar to that which is used by the pharmaceutical industry, including an "academic" representative. Its effect was assessed by audits that were performed before and after the first interventional campaign and again, one year later, after the second interventional campaign. The proportion of antibiotic courses that were assessed as satisfactory in terms of duration increased significantly after the first campaign in the hospitals where the intervention was mounted. No significant changes in prescribing occurred in the control hospitals. In the hospitals which were control hospitals in 1985, and in which the intervention occurred in 1986, the proportion of antibiotic courses that were assessed as satisfactory also increased significantly after the interventional campaign. A fall-off in performance occurred during the 12 months after the campaign in the 1985-interventional hospitals. Calculated cost savings more than outweighed the costs of the campaign. We conclude that inappropriate prescribing behaviour in hospitals can be modified successfully by educational marketing techniques.

We examined gender-specific prevalences, patterns, and correlates of non-prescribed use of pain relievers - mainly opioids - in a representative sample of American adolescents (N=18,678). Data were drawn from the public use data file of the 2005 U.S. National Survey on Drug Use and Health, a survey of non-institutionalized American household residents. The patterns of non-prescribed use of prescription pain relievers were examined, and logistic regression procedures were conducted to identify correlates of non-prescribed use. Approximately one in 10 adolescents aged 12-17 years reported non-prescribed use of pain relievers in their lifetime (9.3% in males and 10.3% in females). The mean age of first non-prescribed use was 13.3 years, which was similar to the mean age of first use of alcohol and marijuana but older than the age of first inhalant use. Among all non-prescribed users, 52% reported having used hydrocodone products (Vicodin, Lortab, Lorcet, and Lorcet Plus, and hydrocodone), 50% had used propoxyphene (Darvocet or Darvon) or codeine (Tylenol with codeine), and 24% had used oxycodone products (OxyContin, Percocet, Percodan, and Tylox). Approximately one quarter (26%) of all non-prescribed users had never used other non-prescribed or illicit drugs. There were gender variations in correlates of non-prescribed use. Use of non-prescribed pain relievers occurs early in adolescence. Research is needed to understand whether early use of non-prescribed pain relievers is related to later drug use.

The association between industry payments to physicians and prescribing rates of the brand-name medications that are being promoted is controversial. In the United States, industry payment data and Medicare prescribing records recently became publicly available. To study the association between physicians' receipt of industry-sponsored meals, which account for roughly 80% of the total number of industry payments, and rates of prescribing the promoted drug to Medicare beneficiaries. Cross-sectional analysis of industry payment data from the federal Open Payments Program for August 1 through December 31, 2013, and prescribing data for individual physicians from Medicare Part D, for all of 2013. Participants were physicians who wrote Medicare prescriptions in any of 4 drug classes: statins, cardioselective β-blockers, angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers (ACE inhibitors and ARBs), and selective serotonin and serotonin-norepinephrine reuptake inhibitors (SSRIs and SNRIs). We identified physicians who received industry-sponsored meals promoting the most-prescribed brand-name drug in each class (rosuvastatin, nebivolol, olmesartan, and desvenlafaxine, respectively). Data analysis was performed from August 20, 2015, to December 15, 2015. Receipt of an industry-sponsored meal promoting the drug of interest. Prescribing rates of promoted drugs compared with alternatives in the same class, after adjustment for physician prescribing volume, demographic characteristics, specialty, and practice setting. A total of 279 669 physicians received 63 524 payments associated with the 4 target drugs. Ninety-five percent of payments were meals, with a mean value of less than $20. Rosuvastatin represented 8.8% (SD, 9.9%) of statin prescriptions; nebivolol represented 3.3% (7.4%) of cardioselective β-blocker prescriptions; olmesartan represented 1.6% (3.9%) of ACE inhibitor and ARB prescriptions; and desvenlafaxine represented 0.6% (2.6%) of

Objective To explore types of e-prescribing errors in community pharmacies and their potential consequences, as well as the factors that contribute to e-prescribing errors. Methods Data collection involved performing 45 total hours of direct observations in five pharmacies. Follow-up interviews were conducted with 20 study participants. Transcripts from observations and interviews were subjected to content analysis using NVivo 10. Results Pharmacy staff detected 75 e-prescription errors during the 45 hour observation in pharmacies. The most common e-prescribing errors were wrong drug quantity, wrong dosing directions, wrong duration of therapy, and wrong dosage formulation. Participants estimated that 5 in 100 e-prescriptions have errors. Drug classes that were implicated in e-prescribing errors were antiinfectives, inhalers, ophthalmic, and topical agents. The potential consequences of e-prescribing errors included increased likelihood of the patient receiving incorrect drug therapy, poor disease management for patients, additional work for pharmacy personnel, increased cost for pharmacies and patients, and frustrations for patients and pharmacy staff. Factors that contribute to errors included: technology incompatibility between pharmacy and clinic systems, technology design issues such as use of auto-populate features and dropdown menus, and inadvertently entering incorrect information. Conclusion Study findings suggest that a wide range of e-prescribing errors are encountered in community pharmacies. Pharmacists and technicians perceive that causes of e-prescribing errors are multidisciplinary and multifactorial, that is to say e-prescribing errors can originate from technology used in prescriber offices and pharmacies.

To investigate if a pending application for disability pension had an influence on the applicant's purchase of medical drugs, with a particular focus on musculoskeletal disorders and the use of painkillers. We performed a registry-based follow-up study including 12,020 applicants for disability pension in a Danish county from 1995 to 2000 and linked this information to a database of drug prescriptions. Purchase of drug was calculated for the 6-month period just before the decision and for the 6-month period 2 years later. Changes in a 2-year time period were estimated by differences in purchase rates. Furthermore, the proportion of applicants with an increased purchase of drugs and the proportion of applicants who ceased buying drugs were estimated. The results were stratified by diagnosis and result of application (awarded/rejected). The analyses were furthermore restricted to musculoskeletal disorders and the use of painkillers. At baseline 81% had a purchase and after the 2-year time period 11% ceased buying prescribed drugs. Half of all applicants increased the purchase of drugs. For musculoskeletal disorders one third had an increased purchase rate of painkillers while one fourth ceased purchase of drugs with variations in different diagnostic subgroups. The major changes of drug purchase after a pending application for disability pension are probably ascribed to characteristics of the diseases underlying the disability.

Oral antihyperglycaemic prescription trends keep on changing and thus the drug prescription trend study may prove to be powerful exploratory tool for health care providers. To investigate trends in prescriptions of oral antihyperglycaemic drugs (OHDs) among postmenopausal women suffering from T2DM in India and evaluate the rationality and adherence to ADA treatment guidelines. An observational, cross-sectional descriptive prescription audit (n=500) was carried. Postmenopausal women were interviewed in their local language using pre-tested pre validated questionnaire after verbal informed consent at a teaching tertiary care hospital of north India. Oral antihyperglycaemic drugs (OHDs) drugs were categorized as per the pharmacological classification. Adherence to available clinical practice guidelines/recommendations issued under American Diabetes Association (ADA) 2015 Guidelines as well as rationality of these prescriptions were assessed using WHO Guide to Good Prescribing. Mean age of the study population was 58.14±12.86. Mean duration since menopause was 5.3 years and of T2DM was 9.5 years. A 93.4% of the prescriptions had only OHDs whereas 6.6% of the prescriptions had various insulin preprations + OHDs (p<0.0001). Biguanides followed by sulfonylureas, thiazolidinediones, DPP-inhibitors and alpha-glucosidases inhibitor were prescribed in 85.6%, 59.8%, 26.6%, 26% and 12.2% respectively as monotherapy or in combination. Among biguanides, metformin was the most frequently prescribed OHDs. In spite of black box warning on pioglitazone, it was prescribed in 26.6% as FDC. However, clear increase use of vidagliptine was noticed upto 26%. Among combinations most frequent was metformin plus glimipride followed by voglibose plus metformin, whereas, among FDC, metformin plus glimipride followed by metformin plus vidagliptine were most frequently prescribed. Metformin was the most common OHDs to be prescribed followed by glimepiride. Although pioglitazone still continues

Objective To examine pharmaceutical advertisements in medical journals for their adequacy of information. Methods We selected a convenience sample of 5 major Russian medical journals covering different fields of medicine and different types of publications. We evaluated all the ads in all the issues of the selected journals published during 1998. We counted the number of appearances of trade, chemical, and generic names; indication and contraindication; pharmacologic group; safety warnings; and references. Counts in all categories were aggregated for each advertiser. Results There were 397 placements of 207 distinct advertisements. Only 154 placements (40%) mentioned the generic name, 177 (45%) mentioned any indication, 42 (11%) mentioned safety warnings and contraindications, 21 (5%) warned about drug interactions, and 8 (2%) provided references. The 6 companies responsible for the most ads on average provided less information than the other companies. Conclusions Almost none of the drug ads published in Russian medical journals provide the basic information required for appropriate prescribing. This is despite the fact that in Russia, ads that omit essential information and that could lead consumers to misunderstandings about an advertised product are illegal. The arrival of drug advertising in Russia has brought little information and has been potentially damaging. PMID:11381003

Use of behavioral economics and social psychology to improve treatment of acute respiratory infections (BEARI): rationale and design of a cluster randomized controlled trial [1RC4AG039115-01] - study protocol and baseline practice and provider characteristics

PubMed Central

2013-01-01

Background Inappropriate antibiotic prescribing for nonbacterial infections leads to increases in the costs of care, antibiotic resistance among bacteria, and adverse drug events. Acute respiratory infections (ARIs) are the most common reason for inappropriate antibiotic use. Most prior efforts to decrease inappropriate antibiotic prescribing for ARIs (e.g., educational or informational interventions) have relied on the implicit assumption that clinicians inappropriately prescribe antibiotics because they are unaware of guideline recommendations for ARIs. If lack of guideline awareness is not the reason for inappropriate prescribing, educational interventions may have limited impact on prescribing rates. Instead, interventions that apply social psychological and behavioral economic principles may be more effective in deterring inappropriate antibiotic prescribing for ARIs by well-informed clinicians. Methods/design The Application of Behavioral Economics to Improve the Treatment of Acute Respiratory Infections (BEARI) Trial is a multisite, cluster-randomized controlled trial with practice as the unit of randomization. The primary aim is to test the ability of three interventions based on behavioral economic principles to reduce the rate of inappropriate antibiotic prescribing for ARIs. We randomized practices in a 2 × 2 × 2 factorial design to receive up to three interventions for non-antibiotic-appropriate diagnoses: 1) Accountable Justifications: When prescribing an antibiotic for an ARI, clinicians are prompted to record an explicit justification that appears in the patient electronic health record; 2) Suggested Alternatives: Through computerized clinical decision support, clinicians prescribing an antibiotic for an ARI receive a list of non-antibiotic treatment choices (including prescription options) prior to completing the antibiotic prescription; and 3) Peer Comparison: Each provider’s rate of inappropriate antibiotic prescribing relative to top

To assess the evidence of the effectiveness of different categories of interruptive medication prescribing alerts to change prescriber behavior and/or improve patient outcomes in hospital computerized provider order entry (CPOE) systems. PubMed, Embase, CINAHL and the Cochrane Library were searched for relevant articles published between January 2000 and February 2016. Studies were included if they compared the outcomes of automatic, interruptive medication prescribing alert/s to a control/comparison group to determine alert effectiveness. Twenty-three studies describing 32 alerts classified into 11 alert categories were identified. The most common alert categories studied were drug-condition interaction (n=6), drug-drug interaction alerts (n=6) and corollary order alerts (n=6). All 23 papers investigated the effect of the intervention alert on at least one outcome measure of prescriber behavior. Just over half of the studies (53%, n=17) reported a statistically significant beneficial effect from the intervention alert; 34% (n=11) reported no statistically significant effect, and 6% (n=2) reported a significant detrimental effect. Two studies also evaluated the effect of alerts on patient outcome measures; neither finding that patient outcomes significantly improved following alert implementation (6%, n=2). The greatest volume of evidence relates to three alert categories: drug-condition, drug-drug and corollary order alerts. Of these, drug-condition alerts had the greatest number of studies reporting positive effects (five out of six studies). Only two of six studies of drug-drug interaction and one of six of corollary alerts reported positive benefits. The current evidence-base does not show a clear indication that particular categories of alerts are more effective than others. While the majority of alert categories were shown to improve outcomes in some studies, there were also many cases where outcomes did not improve. This lack of evidence hinders decisions

Background: Opioid analgesics and benzodiazepines are often misused in clinical practice. We determined whether implementation of a centralized prescription network offering real-time access to patient-level data on filled prescriptions (PharmaNet) reduced the number of potentially inappropriate prescriptions for opioids and benzodiazepines. Methods: We conducted a time series analysis using prescription records between Jan. 1, 1993, and Dec. 31, 1997, for residents of the province of British Columbia who were receiving social assistance or were 65 years or older. We calculated monthly percentages of filled prescriptions for an opioid or a benzodiazepine that were deemed inappropriate (those issued by a different physician and dispensed at a different pharmacy within 7 days after a filled prescription of at least 30 tablets of the same drug). Results: Within 6 months after implementation of PharmaNet in July 1995, we observed a relative reduction in inappropriate filled prescriptions for opioids of 32.8% (95% confidence interval [CI] 31.0%–34.7%) among patients receiving social assistance; inappropriate filled prescriptions for benzodiazepines decreased by 48.6% (95% CI 43.2%–53.1%). Similar and statistically significant reductions were observed among residents 65 years or older. Interpretation: The implementation of a centralized prescription network was associated with a dramatic reduction in inappropriate filled prescriptions for opioids and benzodiazepines. PMID:22949563

Introduction: Evidence has shown that utilization of antiosteoporotic medications does not correspond with risk, and studies on other therapies have shown that adequacy of pharmaceutical prescribing might vary between regions. Nevertheless, very few studies have addressed the variability in osteoporotic drug consumption. We aimed to describe variations in pharmaceutical utilization and spending on osteoporotic drugs between Health Areas (HA) in Spain. Methods: Population-based cross-sectional ecological study of expenditure and utilization of the five therapeutic groups marketed for osteoporosis treatment in Spain in 2009. Small area variation analysis (SAVA) methods were used. The units of analysis were the 168 HA of 13 Spanish regions, including 7.2 million women aged 50 years and older. The main outcomes were the defined daily dose (DDD) per 1000 inhabitants and day (DDD/1000/Day) dispensed according to the pharmaceutical claims reimbursed, and the expenditure on antiosteoporotics at retail price per woman ≥50 years old and per year. Results: The average osteoporosis drug consumption was 116.8 DDD/1000W/Day, ranging from 78.5 to 158.7 DDD/1000W/Day between the HAs in the 5th and 95th percentiles. Seventy-five percent of the antiosteoporotics consumed was bisphosphonates, followed by raloxifene, strontium ranelate, calcitonins, and parathyroid hormones including teriparatide. Regarding variability by therapeutic groups, biphosphonates showed the lowest variation, while calcitonins and parathyroid hormones showed the highest variation. The annual expenditure on antiosteoporotics was €426.5 million, translating into an expenditure of €59.2 for each woman ≥50 years old and varying between €38.1 and €83.3 between HAs in the 5th and 95th percentiles. Biphosphonates, despite accounting for 79% of utilization, only represented 63% of total expenditure, while parathyroid hormones with only 1.6% of utilization accounted for 15% of the pharmaceutical spending

Oxygen is a widely used drug in the hospital setting. However, international audits suggest that oxygen administration practices are often not compliant with prescribed standards. This can place patients at risk and cause serious adverse events. To analyse data related to recent practices of oxygen prescription and administration at Royal Perth Hospital (RPH), Western Australia. The results of this audit aim to guide further research on possible interventional studies implementing key solutions. All patients who received care in the Acute Medical Unit at RPH between 1 September and 14 September 2015 were included in this audit. Patients who were given supplemental oxygen during their admission were selected for further review of records. Appropriate medically indicated target oxygen saturations for each patient were judged under consultation with a respiratory specialist. A total of 65 patients received oxygen supplementation within the study period; 36 of these patients (55.4%) had target oxygen saturations prescribed by doctors, and 25% of the prescribed targets were judged to be inappropriate. In total, 49 patients (75.4%) were exposed to a potential risk from oxygen therapy due to prescription error and/or delivery error. A real risk was identified in 19 patients (29.2%) as they received oxygen at levels outside their appropriate medically indicated target range. The current practices of oxygen prescription and administration within RPH are suboptimal. Patients are placed at risk of oxygen toxicity due to deviation from oxygen prescription guidelines. © 2017 Royal Australasian College of Physicians.

Potentially inappropriate medication (PIM) is associated with an increased risk for detrimental health outcomes in elderly patients. Some antidepressant drugs are considered as PIM, but previous research on the association between antidepressants and subsequent dementia has been inconclusive. Therefore, we investigated whether the intake of antidepressants, particularly of those considered as PIM according to the Priscus list, would predict incident dementia. We used data of a prospective cohort study of non-demented primary care patients (n = 3239, mean age = 79.62) to compute Cox proportional hazards models. The risk for subsequent dementia was estimated over eight follow-ups up to 12 years depending on antidepressant intake and covariates. The intake of antidepressants was associated with an increased risk for subsequent dementia (HR = 1.53, 95% CI: 1.16-2.02, p = .003; age-, sex-, education-adjusted). PIM antidepressants (HR = 1.49, 95% CI: 1.06-2.10, p = .021), but not other antidepressants (HR = 1.04, 95% CI: 0.66-1.66, p = .863), were associated with an increased risk for subsequent dementia (in age-, sex-, education-, and depressive symptoms adjusted models). Significant associations disappeared after global cognition at baseline was controlled for. Methodological limitations such as selection biases and self-reported drug assessments might have influenced the results. Only antidepressants considered as PIM were associated with an increased subsequent dementia risk. Anticholinergic effects might explain this relationship. The association disappeared after the statistical control for global cognition at baseline. Nonetheless, physicians should avoid the prescription of PIM antidepressants in elderly patients whenever possible. Copyright © 2017 Elsevier B.V. All rights reserved.

Importance In an effort to regulate physician conflicts of interest, some US academic medical centers (AMCs) enacted policies restricting pharmaceutical representative sales visits to physicians (known as detailing) between 2006 and 2012. Little is known about the effect of these policies on physician prescribing. Objective To analyze the association between detailing policies enacted at AMCs and physician prescribing of actively detailed and not detailed drugs. Design, Setting, and Participants The study used a difference-in-differences multivariable regression analysis to compare changes in prescribing by physicians before and after implementation of detailing policies at AMCs in 5 states (California, Illinois, Massachusetts, Pennsylvania, and New York) that made up the intervention group with changes in prescribing by a matched control group of similar physicians not subject to a detailing policy. Exposures Academic medical center implementation of policies regulating pharmaceutical salesperson visits to attending physicians. Main Outcomes and Measures The monthly within-drug class market share of prescriptions written by an individual physician for detailed and nondetailed drugs in 8 drug classes (lipid-lowering drugs, gastroesophageal reflux disease drugs, diabetes drugs, antihypertensive drugs, hypnotic drugs approved for the treatment of insomnia [sleep aids], attention-deficit/hyperactivity disorder drugs, antidepressant drugs, and antipsychotic drugs) comparing the 10- to 36-month period before implementation of the detailing policies with the 12- to 36-month period after implementation, depending on data availability. Results The analysis included 16 121 483 prescriptions written between January 2006 and June 2012 by 2126 attending physicians at the 19 intervention group AMCs and by 24 593 matched control group physicians. The sample mean market share at the physician-drug-month level for detailed and nondetailed drugs prior to enactment of policies
