Abstract
Background Potentially inappropriate medications (PIMs) use often cause to poor health outcomes in older patients. There is a dearth of information on PIMS use in this population of patients seeking treatment at Hiwot Fana Comprehensive Specialized Hospital. Objective To assess PIMs use and associated factors among older patients receiving follow-up treatment at the chronic care clinic of Hiwot Fana Comprehensive Specialized Hospital in eastern Ethiopia. Methods A retrospective cross-sectional study using medical records of 419 older patients was conducted. older patients, aged 65 years or older, treated in the ambulatory care clinic were included. Simple random sampling technique was used. PIMs use was identified by using the 2023 American Geriatrics Society Beers Criteria (AGS Beers Criteria) and Screening Tool of Older People's Potentially Inappropriate Prescriptions Criteria and Screening Tool to Alert Doctors to Right Treatment (STOPP/START) version 2 criteria. The multivariable logistic regression analysis was employed to identify factors associated with PIMs use. The strength of statistical association was measured by adjusted odds ratio (aOR) and 95% CI. P values < 0.05 were considered statistically significant. Results A total of 419 patients' medical records were reviewed. Of these, 411 patients' medical records fulfilled the inclusion criteria and were considered for final analysis. About 56.9% (n= 234) of the study population was women. The prevalence of PIMs use was 28.5% and 18.5%, according to 2023 AGS Beers Criteria and STOPP/START version 2 criteria, respectively. In accordance with 2023 AGS Beers Criteria, male sex (aOR = 1.78; 95% CI, 1.10-2.87), diabetes mellitus (aOR = 0.35; 95% CI, 0.19-0.62), and chronic kidney disease (aOR = 6.68; 95% CI, 2.55-9.32) were found to be the determining factors for PIMs use. According to STOPP/START version 2 criteria, deep vein thrombosis, diabetes mellitus, hypertension, and advanced age were the primary factors influencing PIMs use. Conclusions Compared with other study findings from across the world, the prevalence of PIMs use was low. Based on 2023 AGS Beers Criteria, male sex, diabetes mellitus, and chronic kidney disease were found to be the determinant factors for PIMs use. Deep vein thrombosis, diabetes mellitus, hypertension, and advanced age were significant factor of PIMs use according STOPP/START version 2 criteria.

Patterns of Medication Management and Associated Medical and Clinical Features among Home-Dwelling Older Adults: A Cross-Sectional Study in Central Portugal. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1701. [PMID: 36767067 PMCID: PMC9914088 DOI: 10.3390/ijerph20031701] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 01/11/2023] [Accepted: 01/12/2023] [Indexed: 06/18/2023]
Abstract
Ageing is frequently associated with multimorbidity and polypharmacy. The present study aimed to identify the current medication management patterns and the profiles of home-dwelling older adults and to find any association with their conditions, including frailty and cognitive impairment. Within the scope of this cross-sectional study, 112 older adults living in the community were assessed via face-to-face structured interviews. Frailty, cognitive status, medication management and clinical and sociodemographic variables were evaluated. Descriptive and inferential statistics were calculated. The mean participant age was 76.6 ± 7.1 years, 53.6% of participants were women, and 40.2% of participants lived alone. More than half were classified as having frailty (58.9%), almost one-fifth (19.6%) presented with a moderate cognitive impairment had more than one disease, and 60.7% were polymedicated. No associations were found between polymedication and medication self-management, the use of over-the-counter medications, living alone, having a poor understanding of pharmacological therapy and/or pathology, or having more than one prescriber. Self-management was associated with age, the number of medications, frailty and cognitive status. Binary logistic regressions showed that cognitive impairment had statistically significant differences with medication management, having a poor understanding of pharmacological therapy and/or pathology, having one prescriber and the use of medications not prescribed by physicians. Interventions to prevent medication-related problems in home-dwelling older adults are recommended.

The Prevalence of Polypharmacy and Potentially Inappropriate Medications and Its Relationship with Cognitive Status in Portuguese Institutionalized Older Adults: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19052637. [PMID: 35270323 PMCID: PMC8910092 DOI: 10.3390/ijerph19052637] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 02/15/2022] [Accepted: 02/20/2022] [Indexed: 11/25/2022]
Abstract
The aim of this study was to evaluate the prevalence of polypharmacy and potentially inappropriate medications (PIMs) in a population of older adults living in nursing homes. Furthermore, we also intended to assess the possible association between polypharmacy, potentially inappropriate medications and cognitive impairment in institutionalized older adults. A cross-sectional study analyzed data from 193 nursing home residents in the district of Viseu, Portugal, between September 2018 and June 2019, with a mean age of 82.4 ± 6.2 years (ranging from 65 to 95 years old); 72.5% (n = 140) were female participants. Major polypharmacy was presented in 80.8% of the study population, who took 7.6 ± 3.3 drugs per day. Using the Beers Criteria, we found that 79.3% took PIMs. There was a positive association between polypharmacy and PIM (p < 0.001), showing that higher medicines intake increased the number of PIMs. Polypharmacy was not associated with the functionality of the older adults to perform activities of daily living, but was associated with cognitive impairment. The older adults with lower scores on the Mini Mental State Examination (MMSE) took more drugs (p = 0.039) and used more PIM (p < 0.001). Moreover, patients taking five or more prescription drugs per day (major polypharmacy) consuming any psychiatric, gastrointestinal or oral antidiabetic agents (regardless of whether they were considered potentially inappropriate or not) had higher odds of displaying cognitive impairment than those who did not (p < 0.05). Older adult residents of the studied nursing homes were potentially affected by polypharmacy and inappropriate polypharmacy. This observation reveals the need to adopt and implement strategies that make drug therapy more adequate and safer for older adults.

Abstract
PURPOSE Long-Term Care (LTC) systems have experienced recent developments driven by changes in healthcare and demography (e.g. population ageing). As well, pharmacists are changing from traditional roles to more patient-oriented services. The present study aimed to identify and assess pharmacists' and/or pharmacy-based interventions in institutional LTC settings, also mapping relevant medications. METHODS The review was undertaken in general accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), using three main literature databases (PubMed, Scopus, and Web of Knowledge). A set of 16 keywords, divided into three domains (professional, type of care and type of setting), were combined into search equations. Selected studies were assessed through the Quality Assessment Tool for Quantitative Studies. RESULTS Twenty-six studies met the inclusion criteria, out of 794 initial hits. Most studies (12) described pharmacist/pharmacy-driven interventions assessing Medication Management Reviews' impact in different endpoints or outcomes. Other studies (3) assessed pharmacists' interventions on specific medication groups. Good Administration Practices, new pharmaceutical care models, antibiotic stewardship programs, and studies assessing other pharmacists' interventions, such as pharmacy-managed informatics and education, were addressed by 11 other papers. Six studies were classified as Strong after quality assessment. CONCLUSION LTC is a clinically complex type of care benefiting from interdisciplinary work. Despite the overall lower quality of the identified studies, pharmacists perform in a wide array of LTC areas. The broad implementation of pharmaceutical activities in institutional LTC settings opens opportunities to optimise medicines' use.

Abstract
OBJECTIVES To measure the prevalence of cases of potentially inappropriate prescribing (PIP) for older patients and to identify the risk factors for identified cases of PIP. METHODS STOPP criteria version 2 were used for identifying cases of PIP for older patients (>65 years) who were admitted to a tertiary hospital in Jordan over a period of 18 months. Data were collected by prospectively reviewing the clinical and prescription records of included patients. Descriptive analysis, univariate analysis and multiple linear regression were used to analyse the results. RESULTS Upon admission, during hospitalisation and on discharge, 144, 182 and 156 cases of PIP were identified, respectively. There was a statistically significant association between the number of prescribed medications and cases of PIP during the hospital journey (P < .05). CONCLUSION Inappropriate prescribing of medications is highly prevalent among older patients. Application of validated (STOPP) criteria can help to detect and direct development of interventions to prevent PIP occurrence among older patients.

Abstract
Pharmacological therapy in the elderly is particularly complicated and challenging. Due to coexistence of three main predisposing factors (advanced age, multiple morbidity and polypharmacotherapy), this group of patients is prone to occurrence of drug interactions and adverse effects of incorrect drug combinations. Since many years patient safety during the treatment process has been one of key elements for proper functioning of healthcare systems around the world, thus different preventive measures have been undertaken in order to counteract factors adversely affecting the therapeutic effect. One of the avoidable medical errors is pharmacological interactions. According to estimates, one in six elderly patients may be at risk of a significant drug interaction. Hence the knowledge about mechanisms and causes of drug interactions in the elderly, as well as consequences of their occurrence are crucial for planning the process of pharmacotherapy. For the purpose of pharmacovigilance, a review of available methods and tools gives an insight into possible ways of preventing drug interactions. Additionally, recognizing the actual scale of this phenomenon in geriatric population around the world emphasizes the importance of a joint effort among medical community to improve quality of pharmacotherapy.

Abstract
PURPOSE The increase in drug prescription for the elderly raises the risk of the occurrence of potentially inappropriate medications (PIMs), thus increasing the incidence of drug-related problems. Likewise, potential prescribing omissions (PPOs) are also highly prevalent in the elderly. This study aimed at assessing the prevalence of PIMs in the elderly by using the EU(7)-PIM list, STOPP criteria version 2 and the Beers criteria version 2015, as well as the prevalence of PPOs by applying the START criteria version 2 in elderly nursing home residents and outpatients of the Eastern Central Region of Portugal. PATIENTS AND METHODS A descriptive cross-sectional study was carried out in a sample of 90 Portuguese elderly people. Age, gender, diagnoses and medication history were collected from the patients' clinical records. The prevalence of PIMs and PPOs was measured according to each of the criteria applied. RESULTS The patients' ages ranged from 65 to 103 years, with an average age of 84.15 years. In addition, the average number of medications prescribed was 7.6. The STOPP criteria identified 250 PIMs affecting 77 patients (85.5%), the EU(7)-PIM list detected 94 PIMs in 58 patients (64.4%) and the Beers criteria identified 69 PIMs in 51 patients (56.6%). Therefore, the STOPP criteria version 2 identified substantially more PIMs than the other two tools. Furthermore, by applying the START criteria 68 PPOs were detected in 52 patients (57.7%). CONCLUSION A high prevalence of PIMs and PPOs was observed, suggesting the need to implement actions aimed at reducing the phenomenon and thus help to improve the quality of care provided in nursing homes. The variations in prevalence with the different tools suggest the need to carefully choose the tool for medication review in the elderly.

Abstract
Inappropriate prescribing is a risk factor for adverse drug reactions and hospitalizations in the elderly and places a considerable burden on the healthcare system. Hence, it is imperative to identify irrational prescribing and implement interventions to improve prescribing appropriateness in geriatric clinical practice. This study aimed to determine: (i) the prevalence of potentially inappropriate medications (PIMs) according to Beers STOPP, FORTA, and the Medication Appropriateness Index (MAI) criteria; (ii) the prevalence of potential prescribing omissions (PPOs) according to START criteria; and (iii) the predictors for PIMs and PPOs. A cross-sectional study was performed among elderly outpatients of 10 primary healthcare centers with specialized geriatric clinics in Kuwait. Four-hundred and seventy-eight patients were selected randomly, 420 (87.9%) agreed to participate. Data about chronic diseases and prescribed medications were obtained from the physicians by accessing the patients’ medical records. Descriptive and multivariable logistic regression were used for data analysis. A total of 2645 medications were prescribed to all patients; mean (SD) number of medicines per patient was 6.3 (3.0). PIMs were present in 53.1%, 55.7%, and 44.3% of respondents, according to Beers, STOPP, and FORTA criteria, respectively. Almost 74% of respondents had one or more inappropriate ratings among their medications in the MAI criteria. According to START criteria, 19.8% of patients had at least one PPO. Respondents taking ≥ 5 medications were found to be using more PIMs according to Beers (OR: 6.3), STOPP (OR: 3.3), FORTA (OR: 6.0) and MAI (OR: 3.9) criteria in comparison to those taking ≤ 4 medications (p<0.001). The MAI revealed a significantly higher number of medications with inappropriate ratings compared to the Beers, STOPP and FORTA criteria (p<0.001). Taking the MAI as reference standard, STOPP criteria had the highest sensitivity (68.6%) and measure of agreement (Kappa index = 0.40) to detect PIMs compared with Beers and FORTA criteria. Inappropriate prescribing is common among the elderly in the primary geriatric clinics. This necessitates further evaluation of its impact on clinical outcomes and warrants efforts to implement interventions to improve prescribing practice in these settings.

Abstract
BACKGROUND In potentially inappropriate medications harm potentially outweighs benefits. Even appropriately prescribed medications may become inappropriate. They can lead to a high risk of adverse drug reactions, morbidity and mortality. The aim of this study was to determine the prevalence of potentially inappropriate medication in the older adult population attending primary care in Portugal and to identify associated sociodemographic and clinical factors. METHODS We conducted a cross-sectional, analytical study in primary care centres from the five Portuguese healthcare administrative regions and the two autonomous regions. We used a random sample of 757 older patients provided by the information department of the ministry of health (SPMS) and family doctors from the autonomous regions. Data collection occurred March 2018 and we studied sociodemographic characteristics, clinical profile and medication. We used 2015 Beers Criteria to assess potentially inappropriate medications. Logistic regression analyses were performed to determine associations between potentially inappropriate medications' prescriptions and other variables. RESULTS Potentially inappropriate medication was present in 68.6% and 46.1% of the sample had two or more. The likelihood of having potentially inappropriate medication increased significantly with being female (OR=1.56 [1.05 to 2.31]), number of chronic health problems (OR=1.06 [1.01 to 1.13]), number of pharmacological subclasses (OR=1.40 [1.30 to 1.51]) and number of prescribers (OR=1.34 [1.09 to 1.65]). Proton-pump inhibitors, nonsteroidal anti-inflammatory drugs and benzodiazepines were the most commonly found ones. CONCLUSION Potentially inappropriate medication in older adults was found to be a common occurrence in Portugal. It is important that doctors are aware of this problem, namely in the primary care setting due to the longitudinal care.

[PMID: 29730617 PMCID: PMC5942474 DOI: 10.1136/bmjopen-2017-019101] [Citation(s) in RCA: 107] [Impact Index Per Article: 17.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2017] [Revised: 02/13/2018] [Accepted: 02/14/2018] [Indexed: 01/10/2023] Open
Abstract
OBJECTIVE To investigate the epidemiology of medication errors and error-related adverse events in adults in primary care, ambulatory care and patients' homes. DESIGN Systematic review. DATA SOURCE Six international databases were searched for publications between 1 January 2006 and 31 December 2015. DATA EXTRACTION AND ANALYSIS Two researchers independently extracted data from eligible studies and assessed the quality of these using established instruments. Synthesis of data was informed by an appreciation of the medicines' management process and the conceptual framework from the International Classification for Patient Safety. RESULTS 60 studies met the inclusion criteria, of which 53 studies focused on medication errors, 3 on error-related adverse events and 4 on risk factors only. The prevalence of prescribing errors was reported in 46 studies: prevalence estimates ranged widely from 2% to 94%. Inappropriate prescribing was the most common type of error reported. Only one study reported the prevalence of monitoring errors, finding that incomplete therapeutic/safety laboratory-test monitoring occurred in 73% of patients. The incidence of preventable adverse drug events (ADEs) was estimated as 15/1000 person-years, the prevalence of drug-drug interaction-related adverse drug reactions as 7% and the prevalence of preventable ADE as 0.4%. A number of patient, healthcare professional and medication-related risk factors were identified, including the number of medications used by the patient, increased patient age, the number of comorbidities, use of anticoagulants, cases where more than one physician was involved in patients' care and care being provided by family physicians/general practitioners. CONCLUSION A very wide variation in the medication error and error-related adverse events rates is reported in the studies, this reflecting heterogeneity in the populations studied, study designs employed and outcomes evaluated. This review has identified important limitations and discrepancies in the methodologies used and gaps in the literature on the epidemiology and outcomes of medication errors in community settings.

Abstract
Background Potentially inappropriate medications (PIMs) should be avoided by the aged population. The aim of this study was to assess the prevalence of PIMs among Lebanese aged outpatients using Beers criteria of 2012. The secondary objectives were to identify the correlates of the PIMs use and to compare the PIMs prevalence rates as per Beers criteria of 2003 and 2012. Methods This cross-sectional observational study was conducted among aged outpatients of different accredited community pharmacies across Lebanon. Data were collected through a validated questionnaire. The Beers criteria of 2012 were used to evaluate PIMs. The association between PIMs used and independent variables were analyzed by logistic regression. The differences between PIMs use according to Beers criteria 2003 and 2012 were calculated using chi-squared and McNemar’s tests. Results A total of 248 outpatients were analyzed. We identified 112 (45.2%) out of 248 patients taking PIMs. The leading classes of medications identified to cause PIMs were those acting on the central nervous system (71.4%). The factors associated with PIMs use were age, osteoporosis, Alzheimer/dementia, diabetes, and alcohol consumption. PIMs use increased significantly between Beers criteria 2003 and 2012 (Chi-squared test, P<0.001; McNemar’s test, P<0.001). Conclusion Our study showed a high prevalence of PIMs use in Lebanon, which is associated with various correlates. Education of health care providers and medication review should be considered to improve medication safety of older adults.

Abstract
UNLABELLED Background Potentially inappropriate medications (PIMs) are often found in high proportion among the elderly population. The STOPP criteria have been suggested to detect more PIMs in European elderly than the Beers criteria. Objective This study aimed to determine the prevalence of PIMs and potential prescribing omissions (PPOs) in a sample of Portuguese nursing homes residents. Setting Four elderly facilities in mainland Portugal Method A descriptive cross-sectional study was used. Elderly polypharmacy patients were included in the study and their medication (registered in patient clinical records) analysed using the Beers (2012 original version and 2008 version adapted to Portugal), STOPP (Screening Tool of Older Person's Prescriptions) and START (Screening Tool to Alert doctors to Right Treatment) criteria. Data were analysed using univariate and bivariate descriptive statistics, considering a confidence interval of 95 %. MAIN OUTCOME MEASURES Prevalence of PIMs and PPOs. Results The sample included 161 individuals, with a mean age of 84.7 years (SD = 6.35), 68.9 % being female. A total of 807 PIMs and 90 PPOs were identified through the application of the three set of criteria. The prevalence of PIMs using the most recent version of the Beers criteria was 85.1 and 42.1 % for independent and dependent of diagnosis, respectively. The Portuguese adaptation of this same tool indicated a lower prevalence of PIMs, 60.3 and 16.7 %, respectively. The prevalence of PIMs using the STOPP criteria was 75.4 %, whilst the prevalence of PPOs, using START, was 42.9 %. There were significant differences in the mean number of PIMs detected depending on the tool used. (p < 0.001). Conclusions The application of the studied criteria in an elderly sample enabled the identification of a notable amount of PIMs and PPOs, indicating there is room for improving the quality of care. The variation in prevalence indicates careful choice of the tool is a prerequisite for engaging in medication review. Using START/STOPP criteria enabled a more holistic approach to the quality of prescribing in the elderly, highlighting low levels of cardiovascular risk prevention and abuse of psychotropic drugs, aside with system failures largely preventable by electronic prescribing and alert generation.

Abstract
BACKGROUND Currently, people live longer but often with poor quality of life. The decrease in healthy life-years is partly attributable to the institution of polypharmacy to treat various comorbidities. OBJECTIVES The objectives of the study were to determine the prevalence and nature of drug-related problems (DRPs) in polypharmacy elderly patients residing in nursing homes and to test the acceptability of a pharmacist's intervention. METHODS An exposure cohort was constituted in three Portuguese nursing homes, where all polypharmacy (five or more medicines) elderly patients (≥65 years of age) were analysed and then a random stratified sample was extracted to be subject to an intervention. Clinical and therapeutic data were collected and analysed for DRPs and classified according to the II Granada Consensus, by a pharmacist-led team. The intervention was the formulation of a pharmacist's recommendations to prescribers addressing clinically relevant DRPs, along with suggestions for therapy changes. RESULTS The initial sample included 126 elderly patients taking 1332 medicines, where 2109 DRPs were identified. The exposure cohort included 63 patients, with comparable baseline data (p > 0.005). Manifest DRPs occurred in 31.7 % of the intervention group (mainly quantitative ineffectiveness-DRP 4), whereas potential DRPs were identified in 100 % of patients (mainly non-quantitative unsafe-DRP 5). Amongst the DRPs identified, 584 (56.7 %) were reported to prescribers (all types of DRPs) and 113 (11 %) to nurses (only non-quantitative ineffectiveness-DRP 3). A total of 539 pharmacist recommendations were presented to physicians, corresponding to 62 letters sent by mail, each including an average of 8.7 recommendations to solve DRPs present in intervention group (IG) patients. There was a high non-response rate (n = 34 letters; 54.8 %; containing 367 pharmacist recommendations; 68.1 %) and amongst recommendations receiving feedback, only 8.7 % of pharmacist recommendations made were accepted (n = 15). Positive responses were significantly associated with a lower number of recommendations made, whereas a higher number of recommendations increased the odds of no response (p < 0.001). CONCLUSION A pharmacist-led medication review proved useful in identifying DRPs in elderly polypharmacy nursing home residents. Stronger bonds must be developed between healthcare professionals to increase patient safety in the vulnerable institutionalised elderly population.

Abstract
OBJECTIVE To determine medication consumption in the older people from a central area of Oporto; determine the prevalence of prescription of Potentially Inappropriate Medication and to analyse the polypharmacy and other important connected factors. DESIGN, SETTING AND PATIENTS Cross-sectional study with a sample of 747 patients older than 64 years, who were attended in a Primary care health centre: USF Rainha D. Amélia, Oporto, Portugal. MAIN OUTCOME MEASURES identification of all medication prescribed from electronic registers. Polypharmacy was considered more than 5 medication prescribed and Potential Inappropriate Medication was identified by Beers criteria 2012. The socio-demographic factors, diagnosis and health care services use were registered too. Logistic regression analysis was used to determine the association between co-variables. RESULTS There were 89.2% (95%CI: 87.6-92.0) of the studied population with at least one prescription. The polypharmacy was present at 59.2% (95%CI: 55.7-62.7) of people. The Potential Inappropriate Medication was present in 37.0% (95%CI: 33.5-40.5) of the cases. The Potential Inappropriate Medication was related with increasing age [OR=1.02 (95%CI: 1.00-1.05)], polypharmacy [OR=4.45 (95%CI: 3.12-6.36)], and be diagnosed with depression/anxiety [OR=2.18 (95%CI: 1.36-3.51)] and/or arthrosis [OR=1.64 (95%CI: 1.11-2.42)]. CONCLUSION The rate of medication prescription, polypharmacy and the prescription of Potentially Inappropriate Medication are very high in Portuguese population studied. The polypharmacy is the most important factor related with this potential inappropriate medication. The physician need to have carefully with prescription of the anxiolytic and anti-inflammatory pain drugs.

Abstract
OBJECTIVE Adverse drug reactions are more incident among the elderly and are frequently associated to inappropriate prescription for this group. The objective of the current study was to investigate the incidence and the characteristics of emergency department visits, related to inappropriate prescription, at the Hospital Israelita Albert Einstein. METHODS Patients aged 60 years or older, admitted to the emergency department at Unidade Avançada Ibirapuera of Hospital Israelita Albert Einstein, were included in the study. Potentially inappropriate medication for the elderly was evaluated using updated 2003 Beers criteria. RESULTS Over a period of 6 months, 214 individuals were included in the study, being 53.7% male. The mean age was 70.8 years (60-107). A total of 48 registries of inappropriate prescription were recorded in 42 patients (19.6% of sample). An emergency visit related to adverse drug event was verified in 27 individuals (12.5% of the sample). From these patients, 34.5% were admitted to the emergency department because of an adverse event caused by an inappropriate medication. CONCLUSION Inappropriate prescription is frequent among elderly patients admitted to emergency department. A surveillance system and a program to educate physicians on the most recent criteria of appropriate prescription may help reducing emergency visits and adverse drug events in the elderly population.

Abstract
BACKGROUND Potentially inappropriate prescribing (PIP) is one of the main risk factors for adverse drug events (ADEs) in older people. PURPOSE This systematic literature review aims to determine prevalence and type of PIP in community-dwelling older people across Europe, as well as identifying risk factors for PIP. METHODS The PubMed and Web of Science database were searched systematically for relevant manuscripts (January 1, 2000-December 31, 2014). Manuscripts were included if the study design was observational, the study participants were community-dwelling older patients in Europe, and if a published screening method for PIP was used. Studies that focused on specific pathologies or that focused on merely one inappropriate prescribing issue were excluded. Data analysis was performed using R statistics. RESULTS Fifty-two manuscripts were included, describing 82 different sample screenings with an estimated overall PIP prevalence of 22.6 % (CI 19.2-26.7 %; range 0.0-98.0 %). Ten of the sample screenings were based on the Beers 1997 criteria, 19 on the Beers 2003 criteria, 14 on STOPP criteria (2008 version), 8 on START-criteria (2008 version), and 7 on the PRISCUS list. The 24 remaining sample screenings were carried out using compilations of screening methods or used country-specific lists such as the Laroche criteria. It appears that only PIP prevalence calculated from insurance data significantly differs from the other data collection method categories. Furthermore, risk factors most often positively associated with PIP prevalence were polypharmacy, poor functional status, and depression. Drug groups most often involved in PIP were anxiolytics (ATC-code: N05B), antidepressants (N06A), and nonsteroidal anti-inflammatory and anti-rheumatic products (M01A). CONCLUSION PIP prevalence in European community-dwelling older adults is high and depends partially on the data collection method used. Polypharmacy, poor functional status, and depression were identified as the most common risk factors for PIP.

Abstract
WHAT IS KNOWN AND OBJECTIVE Elderly people are the principal consumers of prescription drugs. The more the medication used by the patient, the greater the likelihood there is of the patient being subjected to potentially inappropriate drug therapy (PIDT). PIDT has been measured in the literature with both implicit and explicit tools. The purpose of this review was to assess the use of tools to detect PIDT in various studies and to determine which terms are used to refer to PIDT in practice. METHODS A systematic review was conducted according to the following steps: the first was identification. In this step, studies were selected from different combinations of the descriptors 'aged', 'elderly', 'inappropriate prescribing' and 'drug utilization' in three different languages, using the Embase, Medline, Scielo, Scopus and Web of Science databases. Second, the papers that satisfied the inclusion criteria for data extraction were carefully examined by three evaluators to determine the tools used and terms that referred to PIDT. RESULTS AND DISCUSSION From the combinations of keywords, 8610 articles were found. At the end of the selection process, 119 of the articles complied with the specified criteria. The degree of agreement among evaluators was moderate for the study titles (κ1 = 0·479) and substantial for abstracts (κ2 = 0·647). With respect to the PIDT evaluation criteria used by the studies, 27·7% used two criteria. Of the 27 evaluation criteria identified, the Beers criteria were used by 82·3% of the studies. More than 50 different terms to identify PIDT were found in the literature. WHAT IS NEW AND CONCLUSION This review is the first study to conceptualize and discuss terms that refer to PIDT. At present, there is no consensus regarding terms used to refer to PIDT, with over 50 different terms currently in use. This review shows an increase in the number of articles aimed at evaluating PIDT using implicit and explicit tools.

Abstract
BACKGROUND Complex medication regimens may adversely affect compliance and treatment outcomes. Complexity can be assessed with the medication regimen complexity index (MRCI), which has proved to be a valid, reliable tool, with potential uses in both practice and research. OBJECTIVE To use the MRCI to assess medication regimen complexity in institutionalized elderly people. SETTING Five nursing homes in mainland Portugal. METHODS A descriptive, cross-sectional study of institutionalized elderly people (n = 415) was performed from March to June 2009, including all inpatients aged 65 and over taking at least one medication per day. MAIN OUTCOME MEASURE Medication regimen complexity index. RESULTS The mean age of the sample was 83.9 years (±6.6 years), and 60.2 % were women. The elderly patients were taking a large number of drugs, with 76.6 % taking more than five medications per day. The average medication regimen complexity was 18.2 (±SD = 9.6), and was higher in the females (p < 0.001). The most decisive factors contributing to the complexity were the number of drugs and dosage frequency. In regimens with the same number of medications, schedule was the most relevant factor in the final score (r = 0.922), followed by pharmaceutical forms (r = 0.768) and additional instructions (r = 0.742). CONCLUSION Medication regimen complexity proved to be high. There is certainly potential for the pharmacist's intervention to reduce it as part as the medication review routine in all the patients.

Abstract
BACKGROUND The use of potentially inappropriate medications (PIMs) is common in the older population. Inappropriate medications as well as polypharmacy expose older people to a greater risk of adverse drug reactions and may result in hospitalizations. OBJECTIVE To evaluate the prevalence of PIMs among acutely hospitalized patients aged ≥65 years in an acute medical unit, and to investigate the relationship between use of PIMs and weakness. SETTING This longitudinal observational study was undertaken in the Acute Medical Unit, Hvidovre Hospital, University of Copenhagen, Denmark. METHOD Patients aged ≥65 years admitted to the acute medical unit during the period October to December 2011 were included. Patients were interviewed at admission and at a follow-up visit 30 days after discharge. Data included information about medications, social status, functional status, cognitive status, handgrip strength, health-related quality of life, visual acuity, days of hospitalization, and comorbidities, and was prospectively collected. Polypharmacy was defined as regular use of 5 or more drugs. The Charlson Comorbidity Index was used to categorize comorbidities. MAIN OUTCOME MEASURE The prevalence of PIMs and the association with PIMs and functional status handgrip strength, HRQOL, comorbidities, social demographic data and vision. RESULTS Seventy-one patients (55 % men) with a median age of 78.7 years participated. The median number of medications was eight per person. Eighty percent were exposed to polypharmacy. PIMs were used by 85 % of patients, and PIMs were associated with low functional status (p = 0.032), low handgrip strength (p = 0.006), and reduced health-related quality of life (p = 0.005), but not comorbidities (p = 0.63), age (p = 0.60), sex (p = 0.53), education (p = 0.94), cognition (p = 0.10), pain (p = 0.46), or visual acuity (p = 0.55). CONCLUSIONS Use of PIMs was very common among older people admitted to an acute medical unit. The use of PIMs is associated with low functional status, low handgrip strength, and reduced health-related quality of life.

Abstract
Potentially inappropriate medication (PIM) use is a significant worldwide public health problem. Community-dwelling older adults are susceptible to the negative outcomes associated with the use of PIMs. A database search (January 1991-June 2013) produced 19 prospective correlational and 10 intervention studies. The current state of the science reveals that conceptual clarity is lacking regarding the use of PIMs. The prevalence of PIM use is well documented in an abundance of descriptive studies. However, researchers have not examined an intervention's effects on health outcomes in community-dwelling older adults. Although independent older adults can acquire PIMs outside of a provider, current interventions aim to change the behavior of the prescribing physician and pharmacist. Nurses need to collaborate with other disciplines in PIM use research. Priority needs are to design interventions that reduce the use of PIMs and negative health outcomes.

Abstract
BACKGROUND The use of potentially inappropriate medications (PIM) among the elderly is a serious public health problem because it is intrinsically linked to increased morbidity and mortality, causing high costs to public health systems. This study's objective was to verify the prevalence of and the factors associated with the use of PIMs by elderly Brazilians in institutional settings. METHODS We performed a transversal study, by consulting the case files of elderly people living in Long Term Care for the Elderly (LTC) in towns in the State of São Paulo, Brazil, as well as structured interviews with the nurses responsible for them.We identified PIMs using the list of recently updated Beers criteria developed by a group of specialists from the American Geriatrics Society (AGS), who reviewed the criteria based on studies with high scientific evidence levels. We defined the factors studied to evaluate the association with PIM use prior to the statistical analyses, which were the chi-square test and multiple logistic regression. RESULTS Among the elderly who used drugs daily, 82.6% were taking at least one PIM, with antipsychotics (26.5%) and analgesics (15.1%) being the most commonly used. Out of all the medications used, 32.4% were PIMs, with 29.7% of these being PIMs that the elderly should avoid independent of their condition, 1.1% being inappropriate medication for older adults with certain illnesses or syndromes, and 1.6% being medications that older adults should use with caution. In the multivariate analysis, the factors associated with PIM use were: polypharmacy (p = 0.0187), cerebrovascular disease (p = 0.0036), psychiatric disorders (p < 0.0001) and dependency (p = 0.0404). CONCLUSIONS The results of this study showed a high prevalence of PIM use in institutionalized elderly Brazilian patients. and the associated factors were polypharmacy, psychiatric disorders, cerebrovascular diseases and dependency.

Abstract
Introduction Polypharmacy and inappropriate prescriptions are prominent prescribing issues with elderly patients. Beers criteria and other guidelines have been developed to assist in the reduction of potentially inappropriate medications prescribed to elderly patients. The objectives of this study were to assess the prescribing pattern for elderly Nigerian outpatients and estimate the prevalence of potentially inappropriate medications among them using the Beers criteria. Methodology This was a prospective cross-sectional study of elderly patients (65 years and above) who were attending the general outpatients clinic of a rural Nigerian hospital. For the drug utilization aspect of the study, drug-use indicators were assessed using established World Health Organization guidelines, while the Beers criteria was used to screen for potentially inappropriate medications. Result The medical records of 220 patients aged 65 years and above were utilized for the study. A total of 837 drugs were prescribed for the patients, giving an average of 3.8 ± 1.3 drugs per person. Antihypertensive drugs accounted for 30.6% of the prescriptions, followed by multivitamins/food supplements (11.5%) and analgesics (10.8%). A review of the prescribed medications using the 2012 Updated Beers Criteria by the American Geriatric Society identified 56 patients with at least one potentially inappropriate medication prescribed giving a rate of 25.5%. The drug groups identified were nonsteroidal anti-inflammatory drugs, antihistamines, and amitriptyline. Conclusion Polypharmacy and prescription of potentially inappropriate medications are major therapeutic issues in Nigeria. There is a need for prescriber training and retraining with emphasis on the geriatric population.

Abstract
CONTEXT AND OBJECTIVES In Brazil, few studies have investigated the prevalence of potentially inappropriate medications (PIMs) among elderly outpatients. This study aimed to determine the prevalence of PIMs prescribed for elderly outpatients, identify the PIMs most commonly involved, and investigate whether age, sex and number of medications are related to prescription of such medications. DESIGN AND SETTING Observational descriptive study developed in the Geriatrics Service of the Central Institute of Hospital das Clínicas (HC), Faculdade de Medicina da Universidade de São Paulo (FMUSP), São Paulo, Brazil. METHODS Prescriptions issued to 1,270 elderly patients (≥ 60 years) were gathered from a database. These prescriptions had been written by geriatricians at a tertiary-level university hospital in São Paulo, Brazil, between February and May 2008. The prescriptions were divided according to sex and age group (60-69, 70-79 and ≥ 80). The Beers criteria were used to evaluate PIMs. RESULTS Most of the sample comprised women (77%) and the mean age was 80.1 years. The mean prevalence of PIM prescriptions was 26.9%. Female sex and number of medications prescribed were associated with prescription of PIMs. The chance of having a PIM prescription was lower among patients ≥ 70 years. CONCLUSION The greater prevalence of PIMs was correlated with female sex. The chance of having a PIM prescription was lower among patients ≥ 70 years and became greater with increasing numbers of medications prescribed (≥ 7).

Abstract
OBJECTIVE To identify tools for measuring the appropriateness of drug therapy useful in patients with multiple chronic conditions. DESIGN We performed a literature review. DATA SOURCES The following database were consulted (December 2009): Pubmed, EMBASE, CINAHL, PsycINFO and Spanish Medical Index (IME) to detect tools for measuring the appropriateness of treatment in patients with multiple chronic conditions, or otherwise elderly or polypharmacy. STUDY SELECTION Studies were identified both qualitative and quantitative methodology, both theoretical and field work, both original and revised work and included work from all areas of the health system. 108 articles were retrieved, of which we selected 59. The consultation of their references include 20 jobs allowed, resulting in a total of 59 articles. DATA EXTRACTION Of all the tools identified, the researchers performed a selection of those with possible utility for classified PP. The articles were classified into implicit and explicit methods and the characteristics of the field works were tabulated. RESULTS We identified two implicit methods (MAI and Hamdy) and 6 explicit methods (Beers criteria, IPET, STOPP/START, ACOVE, CRIME and NORGEP). None was specific to patients with multiple chronic conditions. The questionnaire MAI, the Beers criteria and its modifications are most often used in literature. The advantages of explicit criteria means that many of them have been developed recently. CONCLUSION There are several tools to measure the appropriateness and none of them has been designed for a population of patients with multiple chronic conditions yet, which by its nature requires a specific approach spreads.

Abstract
AIM To explore the prevalence of potentially inappropriate medication (PIM) use in the elderly, to identify the trends and the patterns of prescribing such medication, and to calculate the associated direct medication cost of such practice in a Saudi hospital. METHODS This was a retrospective cross-sectional study of patients who were aged 65 years or older on at least one PIM. The source of our data was outpatient pharmacy prescription records at Riyadh Military Hospital (RMH) for 2002, 2003 and 2004. Beers' explicit criteria for PIM was used to identify these medications. RESULTS A total of 20521 PIM were identified. The prevalence of PIM for 2002, 2003 and 2004 was 2.5%, 2.3% and 2.1%, respectively. A total of 43.6% of the patients had filled a prescription of one PIM, 18% filled two PIM and 38.4% filled three or more PIM. Digoxin accounted for 23.7% of these PIM. The most commonly prescribed medications were cardiovascular medications at 26.7%. The total direct cost that was associated with inappropriate prescribing was 518314 Saudi Riyals (US$138217) during the study period. CONCLUSION PIM prescribing in RMH was less compared with what was published in the literature in other countries. It was unclear whether these results reflect the level of elderly healthcare services provided to RMH patients or because of underreporting. Drug utilization review programs, medical education, recruiting physicians and clinical pharmacists who are specialized in geriatrics, finding safer medications or integration of computer software to detect such medications during prescriptions entry can improve the medical services provided to the elderly.

Abstract
BACKGROUND Inappropriate medication prescription is a common cause of preventable adverse drug events among elderly persons in the primary care setting. OBJECTIVE The aim of this systematic review is to quantify the extent of inappropriate prescription to elderly persons in the primary care setting. METHODS We systematically searched Ovid-Medline and Ovid-EMBASE from 1950 and 1980 respectively to March 2012. Two independent reviewers screened and selected primary studies published in English that measured (in)appropriate medication prescription among elderly persons (>65 years) in the primary care setting. We extracted data sources, instruments for assessing medication prescription appropriateness, and the rate of inappropriate medication prescriptions. We grouped the reported individual medications according to the Anatomical Therapeutic and Chemical (ATC) classification and compared the median rate of inappropriate medication prescription and its range within each therapeutic class. RESULTS We included 19 studies, 14 of which used the Beers criteria as the instrument for assessing appropriateness of prescriptions. The median rate of inappropriate medication prescriptions (IMP) was 20.5% [IQR 18.1 to 25.6%.]. Medications with largest median rate of inappropriate medication prescriptions were propoxyphene 4.52 (0.10-23.30)%, doxazosin 3.96 (0.32 15.70)%, diphenhydramine 3.30 (0.02-4.40)% and amitriptiline 3.20 (0.05-20.5)% in a decreasing order of IMP rate. Available studies described unequal sets of medications and different measurement tools to estimate the overall prevalence of inappropriate prescription. CONCLUSIONS Approximately one in five prescriptions to elderly persons in primary care is inappropropriate despite the attention that has been directed to quality of prescription. Diphenhydramine and amitriptiline are the most common inappropriately prescribed medications with high risk adverse events while propoxyphene and doxazoxin are the most commonly prescribed medications with low risk adverse events. These medications are good candidates for being targeted for improvement e.g. by computerized clinical decision support.

Abstract
BACKGROUND The exposure of elderly patients to potentially inappropriate medication (PIM) is associated with the increased use of health care services. OBJECTIVE To evaluate both the prevalence of and the factors associated with the use of PIM by elderly patients who are being treated in primary healthcare facilities. SETTING Family Health Programme centres in northeastern Brazil. METHOD A prospective survey of the medications used by elderly patients was performed. A total of 142 participants were randomly selected via systematic sampling. Beers criteria were applied to assess the use of PIM among the investigated sample. All of the medications included in these criteria were assessed for their availability in Brazil. The prevalence of inappropriate medications was chosen as an occurrence measure and was compared among the exposure groups using the prevalence ratio (PR) as a measure of association. MAIN OUTCOME MEASURE Prevalence and various factors associated with the use of PIM. Results The prevalence of PIM usage was 34.5 %. The factors that exhibited associations included the following: illiteracy (PR = 1.51; 95 % CI = 1.02-2.24); black skin colour (PR = 1.80; 95 % CI = 1.40-2.32); the use of ≥4 drugs per day (PR = 2.36; 95 % CI = 1.79-3.11); the use of medications prescribed by a doctor (PR = 2.52; 95 % CI = 1.12-5.69), and the use of medications supplied by the Brazilian government (PR = 1.42; 95 % CI = 1.10-1.81). The most frequently prescribed PIM included short-acting nifedipine (34.5 %) and methyldopa (9.1 %). CONCLUSION The data collected in this study indicated a high prevalence of the use of PIM. The factors that contributed the most to this prevalence included medical prescriptions, polypharmacy, medications supplied by the Brazilian National Health System, and black skin colour (specifically, being of African descent).

Abstract
ABSTRACT Objective: To establish the prevalence of potentially inappropriate medications prescribed for elderly patients, to identify the most commonly involved drugs, and to investigate whether age, sex and number of medications were related with the prescription of these drugs. Methods: Prescriptions for 1,800 elderly patients (≥ 60 years) were gathered from a database. These prescriptions were written by general physicians at a tertiary level university hospital in the city of Sao Paulo, Brazil, from February to May 2008. Only one prescription per patient was considered. The prescriptions were classified according to sex and age (60-69, 70-79 and ≥ 80). The Beers criteria (2003 version) were used to evaluate potentially inappropriate medications. Results: Most of the sample comprised women (66.6%) with a mean age of 71.3 years. The mean prevalence of potentially inappropriate medication prescriptions was 37.6%. The 60-69 age group presented the highest prevalence (49.9%). The most frequently prescribed potentially inappropriate medications to women were carisoprodol, amitriptyline, and fluoxetine; amitriptyline, carisoprodol, fluoxetine and clonidine were prescribed more often to men. The female sex (p<0.001; OR=2.0) and number of medications prescribed (p<0.001) were associated with prescription of potentially inappropriate medications. The chance of having a prescription of these drugs was lower among patients aged over 80 years (OR=0.7). The mean number of prescribed medications for both sexes and all age groups was 7.1. The mean number of medications per patient was higher among females (p<0.001); this result was not age-dependent (p=0.285). Conclusion: The prevalence of potentially inappropriate medications was similar to previously reported values in the literature and was correlated with the female sex. The chance of having a potentially inappropriate medication prescription was lower among patients aged over 80 years. The chance of having a potentially inappropriate medications prescription increased proportionally with the number of medications prescribed (≥ 5).

Abstract
BACKGROUND AND OBJECTIVE Inappropriate prescribing in the elderly population is a well-recognized problem in public health. The Beers criteria have been widely used to evaluate the quality of prescribing for the elderly. However, because the Beers criteria were developed in the United States, they are not fully applicable in Italy. The purpose of this study was to establish explicit criteria for potentially inappropriate medication prescribing (PIP) for the elderly and assess the prevalence of and factors associated with PIP among elderly residents in the Local Health Unit of Parma, Italy according to the developed criteria. METHODS A nine-member expert panel was convened to identify a list of inappropriate medications reflecting the Italian prescribing habits. The panel decided to refine and update the 2002 Beers criteria. Consensus through a Nominal Group Technique was reached to classify the identified 23 inappropriate medications into three categories: 17 medications to be always avoided, three medications rarely appropriate, and three medications with some indications but often misused. A retrospective cohort study using the 2006 Parma Local Health Unit automated outpatient prescriptions database was conducted. The cohort comprised 91 741 elderly individuals >or=65 years with at least one prescription medication. PIP was defined as having a prescription claim for at least one inappropriate medication. RESULTS AND DISCUSSION A total of 23 662 elderly in the cohort (25.8%) had at least one PIP. Of these, 14.1% received prescriptions for two medications of concern, and 2.0% for three or more. Using the expert panel's categories, 59.2% of the elderly receiving PIP had prescriptions for drugs that should always be avoided, 33.9% for rarely appropriate drugs, and 19.1% for drugs that have some indications but are often misused. Non-steroidal anti-inflammatory drugs (35.7% of subjects) were the most frequently occurring PIP, followed by ticlopidine (17.6%), doxazosin (15.5%), and amiodarone (13.6%). Female, older age, overall number of drugs prescribed, greater number of chronic conditions were factors associated with greater odds of receiving PIP. CONCLUSION Via the developed criteria, the study corroborates that PIP among elderly outpatients is a substantial issue in Parma Local Health Unit, Italy. Knowledge of the prevalence of PIP and associated factors should gear efforts to develop strategies to reduce PIP in outpatient settings in Italy.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT * Potentially inappropriate prescribing in older people is a well-documented problem and has been associated with adverse drug reactions and hospitalization. * Beers' criteria, Screening Tool of Older Persons' potentially inappropriate Prescriptions (STOPP) and Screening Tool to Alert doctors to Right Treatment (START) are screening tools that have been formulated to help physicians and pharmacists identify potentially inappropriate prescribing and potential prescribing omissions. * The prevalence of potentially inappropriate prescribing and prescribing omissions in the elderly population presenting to hospital with acute illness is high according to STOPP and START criteria. WHAT THIS STUDY ADDS * Potential errors of prescribing and of omission of medicines are prevalent among medically stable older people in primary care. * Screening tools should be incorporated into the everyday practice of primary care doctors and community pharmacists as a means of preventing potential errors of prescribing commission and prescribing omission in older people. AIMS Screening tools have been formulated to identify potentially inappropriate prescribing (IP) in older people. Beers' criteria are the most widely used but have disadvantages when used in Europe. New IP screening tools called Screening Tool of Older Person's Prescriptions (STOPP) and Screening Tool to Alert doctors to Right Treatment (START) have been developed to identify potential IP and potential prescribing omissions (PPOs). The aim was to measure the prevalence rates of potential IP and PPOs in primary care using Beers' criteria, STOPP and START. METHODS Case records of 1329 patients >or=65 years old from three general practices in one region of southern Ireland were studied. The mean age +/- SD of the patients was 74.9 +/- 6.4 years, 60.9% were female. Patients' current diagnoses and prescription medicines were reviewed and the Beers' criteria, STOPP and START tools applied. RESULTS The total number of medicines prescribed was 6684; median number of medicines per patient was five (range 1-19). Overall, Beers' criteria identified 286 potentially inappropriate prescriptions in 18.3% (243) of patients, whilst the corresponding IP rate identified by STOPP was 21.4% (284), in respect of 346 potentially inappropriate prescriptions. A total of 333 PPOs were identified in 22.7% (302) of patients using the START tool. CONCLUSION Potentially inappropriate drug prescribing and errors of drug omission are highly prevalent among older people living in the community. Prevention strategies should involve primary care doctors and community pharmacists.

Abstract
The definition of "polypharmacy" ranges from the use of a large number of medications; the use of potentially inappropriate medications, which can increase the risk for adverse drug events; medication underuse despite instructions to the contrary; and medication duplication. Older adults are particularly at risk because they often present with several medical conditions requiring pharmacotherapy. Cancer-related therapy adds to this risk in older adults, but few studies have been conducted in this patient population. In this review, we outline the adverse outcomes associated with polypharmacy and present polypharmacy definitions offered by the geriatrics literature. We also examine the strengths and weaknesses of these definitions and explore the relationships among these definitions and what is known about the prevalence and impact of polypharmacy.

Abstract
BACKGROUND The use of potentially inappropriate medications can have profound medical consequences for elderly patients and place a substantial burden on the health care system. OBJECTIVES This study was conducted to determine the prevalence of potentially inappropriate medication prescribing at ambulatory care visits by patients aged > or =65 years covered by the Taiwanese National Health Insurance program, to examine the characteristics of and risk factors for such prescribing, and to investigate its influence on health care resource utilization. METHODS Ambulatory care visits by patients aged > or =65 years in 2001-2004 were identified from the National Health Insurance claims database. The 2003 Beers criteria for drugs to be avoided in the elderly were used to identify potentially inappropriate medications prescribed at these visits. Only drugs with the potential to lead to higher-severity adverse events were included. Multivariate logistic regression was used to determine predictors of the prescribing of potentially inappropriate medications at ambulatory care visits. Independent variables in the regression model included patient characteristics (eg, sex, age), physician characteristics (sex, age, and specialty), and visit characteristics (site and prescribed drug number). The dependent variable was visits that included a prescription for a potentially inappropriate medication. RESULTS Overall, 176,661,994 ambulatory care visits by patients aged > or =65 years were identified in 2001-2004. Of these, 19.1% involved a prescription for a potentially inappropriate medication. Although the frequency of potentially inappropriate medication prescribing declined over the study period, 62.5% of elderly patients were exposed to such medications in 2004. The only patient characteristic associated with an increased likelihood of the prescribing of potentially inappropriate medications was female sex (male sex: odds ratio [OR] = 0.982 [95% CI, 0.980-0.983], P < 0.001). Physician characteristics associated with a greater likelihood of the prescribing of potentially inappropriate medications was male sex (OR = 1.206 [95% CI, 1.202-1.210], P < 0.001); older age (43-50 years: OR = 1.021 [95% CI, 1.018-1.025], P < 0.001; >/=51 years: OR = 1.238 [95% CI, 1.235-1.242], P < 0.001); and family medicine/general practice (OR = 1.267 [95% CI, 1.265-1.269], P < 0.001). For visit characteristics, significant associations were found with visits to a primary care clinic (OR = 1.887 [95% CI, 1.881-1.892], P < 0.001) and the number of drugs prescribed (4-6 drugs: OR = 2.701 [95% CI, 2.696-2.706], P < 0.001; > or =7 drugs: OR = 4.528 [95% CI, 4.517-4.538], P < 0.001). The most commonly prescribed types of potentially inappropriate medications were antihistamines (4.8% of all prescriptions in 48.3% of elderly patients), muscle relaxants/antispasmodics (4.0% and 40.3%, respectively), and long-acting benzodiazepines (2.4% and 21.4%). In 2004, the mean number of ambulatory care visits per patient was significantly higher among those who received potentially inappropriate medications compared with those who did not (30.78 vs 16.57, respectively; P < 0.001). Patients who received potentially inappropriate medications also had significantly more emergency department visits (0.27 vs 0.15; P < 0.001) and hospital admissions (0.46 vs 0.27; P < 0.001). CONCLUSION There was a high prevalence of the prescribing of potentially inappropriate medications at ambulatory care visits by elderly patients in Taiwan in 2001-2004.

Abstract
PURPOSE The potential for adverse drug events caused by potentially inappropriate medication (PIM) use in elderly patients at emergency department (ED) visits is a growing concern. The objects of this study were to determine the prevalence, characteristics and risk factors of PIM use among elderly ED visits in Taiwan. METHODS The nationwide computerized claims database of elderly ED visits under the National Health Insurance (NHI) in Taiwan during 2001-2004 was accessed. PIM, independent of diseases diagnoses or conditions and should be generally be avoided in elderly people, was evaluated using the updated 2003 Beers criteria. RESULTS Between 2001 and 2004, 14.7% of total 1 429 463 elderly ED visits with prescriptions had PIM, and 19.3% of elderly people who visited ED received at least one PIM annually. Odds ratio for PIM prescriptions to ED elderly was higher for visits at which more drugs were prescribed, visits at local community hospital, female and older physicians, patients aged 65-69 years and female patients. Common PIM categories were short acting nifedipine, muscle relaxants and anti-spasmodics, antihistamines and ketorolac. When health care resource utilization was compared in 2004, subjects receiving PIM at ED visit had significantly more mean ambulatory care visits, ED visits and hospital admissions than subjects who did not receive PIM. CONCLUSIONS About one fifth of elderly people who visited ED received PIM annually in Taiwan. The public and physicians should be educated, and a computerized drug surveillance system might be needed to avoid PIM prescriptions to the ED elderly patients.

Abstract
BACKGROUND Although increasing attention has been given to the evaluation of use of potentially inappropriate medication in the older European Union (EU) member countries, information on this topic from Central and Eastern Europe is scarce. OBJECTIVES The aims of the present study were: to identify risk factors enhancing the probability of use of potentially inappropriate medication in hospitalized older patients under the conditions of the Slovak healthcare system and to compare our results with previously published European studies. METHODS The evaluation was performed in 600 patients aged > or =65 years, hospitalized in a general hospital between 1 December 2003 and 31 March 2005. To identify the use of potentially inappropriate medication, the Beers 2003 criteria were applied. Particular socio-demographic and clinical characteristics, as well as comorbid medical conditions were evaluated among possible factors enhancing the probability of use of potentially inappropriate medication. RESULTS At least one potentially inappropriate medication was prescribed to 126 (21%) of 600 patients. Multivariate analysis identified polypharmacy [odds ratio (OR) 2.38; 95% confidence interval (CI): 1.50-3.79], depression (OR 2.03; 95% CI: 1.08-3.82), immobilization (OR 1.87; 95% CI: 1.16-3.00) and heart failure (OR 1.73; 95% CI: 1.13-2.64) as factors associated with an increased risk of use of inappropriate medication. In contrast, patients aged > or =75 years had a lower risk of being prescribed potentially inappropriate medication (OR 0.58; 95% CI: 0.39-0.88). CONCLUSIONS Polypharmacy, immobilization, heart failure and depression were documented as predictors of use of potentially inappropriate medication. In depressive patients, drugs other than antidepressants contributed to the extensive use of potentially inappropriate medication. The observed prevalence of use of potentially inappropriate medication in older hospitalized Slovak patients was lower than the prevalence previously documented in Poland and the Czech Republic, but higher than in Croatia and Turkey. The identified risk factors were consistent with previous findings from other parts of Europe.
