Continuity of care, potentially inappropriate medication, and health care outcomes among the elderly: evidence from a longitudinal analysis in Taiwan. Med Care 2013; 50:1002-9. [PMID: 23047791 DOI: 10.1097/mlr.0b013e31826c870f] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND Better continuity of care (COC) is associated with improved health care outcomes, such as decreased hospitalization and emergency department visit. However, little is known about the effect of COC on potentially inappropriate medication. OBJECTIVES This study aimed to investigate the association between COC and the likelihood of receiving inappropriate medication, and to examine the existence of a mediating effect of inappropriate medication on the relationship between COC and health care outcomes and expenses. METHODS A longitudinal analysis was conducted using claim data from 2004 to 2009 under universal health insurance in Taiwan. Participants aged 65 years and older were categorized into 3 equal tertiles by the distribution of COC scores. This study used a propensity score matching approach to assign subjects to 1 of 3 COC groups to increase the comparability among groups. Generalized estimating equations were used to examine the association between COC, potentially inappropriate medication, and health care outcomes and expenses. RESULTS The results revealed that patients with the best COC were less likely to receive drugs that should be avoided [odd ratios (OR), 0.44; 95% confidence interval (CI), 0.43-0.45) or duplicated medication (OR, 0.22; 95% CI, 0.22-0.23) than those with the worst COC. The findings also indicated that potentially inappropriate medication was a partial mediator in the association between COC and health care outcomes and expenses. CONCLUSION Better COC is associated with fewer negative health care outcomes and lower expenses, partially through the reduction of potentially inappropriate medication. Improving COC deserves more attention in future health care reforms.

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
BACKGROUND Inappropriate prescribing of certain medications known as Beers drugs may be harmful to the elderly, because the potential risk for an adverse outcome outweighs the potential benefit. OBJECTIVES (1) To assess Beers drug use in dual enrollees compared to non-duals; (2) to explore the association between dual enrollment status and Beers use, controlling for the effects of age, gender, race/ethnicity, census region, and health status; (3) to assess which medication therapeutic category had the highest Beers use. DESIGN Cross sectional retrospective review of 2007 Centers for Medicare & Medicaid Service Part D data. Potentially inappropriate medication use was assessed, independent of diagnosis, using the 2003 update by Fick et al. FINDINGS The likelihood of Beers drug use among duals approximates that of non-duals (OR 1.023, 95% CI 1.020-1.026). Characteristics associated with the receipt of a Beers medication include Hispanic origin, younger age, female gender, poor health status, and residence outside of the U.S.' Northeast region. Genitourinary products had the highest Beers use within medication therapeutic categories among both dual and non-dual enrollees (21.1% and 19.9%, respectively). CONCLUSIONS Part D data can be successfully used to monitor Beers drug use. With adjustments for several important and easily measured demographic, health, and prescription drug use covariates, Beers drug use appears to be as common among non-dual enrollees as it is among dual enrollees in the Part D program. New Part D drug utilization policies that apply to all beneficiaries may need to be enacted to reduce Beers drug use.

Abstract
OBJECTIVE To evaluate the impact of a real-time computerized decision support tool in the emergency department that guides medication dosing for the elderly on physician ordering behavior and on adverse drug events (ADEs). DESIGN A prospective controlled trial was conducted over 26 weeks. The status of the decision support tool alternated OFF (7/17/06-8/29/06), ON (8/29/06-10/10/06), OFF (10/10/06-11/28/06), and ON (11/28/06-1/16/07) in consecutive blocks during the study period. In patients ≥65 who were ordered certain benzodiazepines, opiates, non-steroidals, or sedative-hypnotics, the computer application either adjusted the dosing or suggested a different medication. Physicians could accept or reject recommendations. MEASUREMENTS The primary outcome compared medication ordering consistent with recommendations during ON versus OFF periods. Secondary outcomes included the admission rate, emergency department length of stay for discharged patients, 10-fold dosing orders, use of a second drug to reverse the original medication, and rate of ADEs using previously validated explicit chart review. RESULTS 2398 orders were placed for 1407 patients over 1548 visits. The majority (49/53; 92.5%) of recommendations for alternate medications were declined. More orders were consistent with dosing recommendations during ON (403/1283; 31.4%) than OFF (256/1115; 23%) periods (p≤0.0001). 673 (43%) visits were reviewed for ADEs. The rate of ADEs was lower during ON (8/237; 3.4%) compared with OFF (31/436; 7.1%) periods (p=0.02). The remaining secondary outcomes showed no difference. LIMITATIONS Single institution study, retrospective chart review for ADEs. CONCLUSION Though overall agreement with recommendations was low, real-time computerized decision support resulted in greater acceptance of medication recommendations. Fewer ADEs were observed when computerized decision support was active.

Abstract
Objectives This study aimed to develop a list of potentially inappropriate drugs for the elderly in Korea using the Delphi technique. Methods A Delphi evaluation with a two-round survey was used to reach a consensus on the criteria for inappropriate medications for the elderly in an outpatient setting. The expert panel consisted of 7 family medicine specialists, 3 psychiatrists, 1 neurologist and 3 clinical pharmacists. The level of inappropriateness was determined by considering clinical importance of the risk and availability of alternative therapy, and was rated on a scale of 1 (very low) to 4 (very high). The drugs were categorized into three groups. The first group (Group 1) was drugs that should be avoided. The second (Group 2) was for drugs that need to be monitored. And the third (Group 3) was for drugs with a low level of risk. Results We took a list of 60 ingredients for drugs and created a list of 57 potentially inappropriate ingredients for the elderly, independent of diagnosis. Forty-two drugs were classified as Group 1. 13 drugs were classified as Group 2. And 2 drugs were classified as Group 3. Ninety-three drugs were potentially inappropriate for the elderly with 29 diagnoses. Groups 1, 2, and 3 included 63, 28, and 3 drugs, respectively. Conclusions This study is an important development of a list of drugs potentially inappropriate for the elderly in Korea. The application of this list may be useful for identifying potentially inappropriate medication uses and decreasing drug-related problems.

Abstract
Achieving safe prescribing in frail older people is difficult owing to age-related physiological changes, multiple comorbidities, multiple medication use and a higher risk of adverse drug events (ADEs). Among people aged 65 years and over, 7–25% are frail. While frailty is recognized as a major public health problem, there is a lack of consensus on the definition of frailty and validated tools that can be used to assess the effects of frailty on pharmacological response in old age. Frail individuals are at higher risk of adverse clinical outcomes, such as hospitalization, falls, disability and mortality. There is also a lack of consensus on the definition of inappropriate medications. Inappropriate medication use is a major contributor to the risk of ADEs in frail older people. Therefore, development and implementation of tools to optimize appropriate use of medications is necessary for the medical care of frail older people.

Abstract
WHAT IS KNOWN AND OBJECTIVE Increasing attention is being paid to inappropriate medication prescribing for the elderly. A growing body of studies have detected a prevalence of inappropriate prescribing ranging from 12% to 40% worldwide, including Regione Emilia-Romagna, Italy. To improve quality of prescribing, a multi-phase pilot project in the Local Health Unit (LHU) of Parma, Regione Emilia-Romagna, was established. This phase aimed to assess primary care physicians' knowledge of appropriate prescribing in elderly patients. METHODS In total, 155 primary care physicians (51% of the total), convened by the LHU of Parma for an educational session, were asked to complete anonymously a 19-item paper survey. Knowledge of inappropriate medication use in the elderly was assessed using seven clinical vignettes based on the 2002 Beers Criteria. Topics tested included hypertension, osteoarthritis, arrhythmias, insomnia and depression. Data regarding physician's perceived barriers to appropriate prescribing for elderly patients were also collected. To evaluate the relationship between physician knowledge scores and physician characteristics, physicians were classified as having a 'low score' (three or below) or a 'high score' (six or more) with respect to their knowledge of prescribing for the elderly. RESULTS AND DISCUSSION All physicians completed the survey. Most physicians (88%) felt confident in their ability to prescribe appropriate medications for the elderly. Thirty-nine physicians (25%) received a 'high score' compared to 26 (17%) who received a 'low score'. 'Lower score' respondents had been in practice for a longer time (P < 0·05) than 'higher score' respondents. Perceived barriers to appropriate prescribing included potential drug interactions (79% of respondents) and the large number of medications a patient is already taking (75%). WHAT IS NEW AND CONCLUSION The study results show an unsatisfactory knowledge of appropriate prescribing among primary care physicians in the LHU of Parma, especially among older physicians. Educational strategies tailored to primary care physicians should be establish to enhance knowledge in this area and improve quality of prescribing.

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
STUDY OBJECTIVE We assess the impact of emergency department (ED) pharmacists on reducing potentially harmful medication errors. METHODS We conducted this observational study in 4 academic EDs. Trained pharmacy residents observed a convenience sample of ED pharmacists' activities. The primary outcome was medication errors recovered by pharmacists, including errors intercepted before reaching the patient (near miss or potential adverse drug event), caught after reaching the patient but before causing harm (mitigated adverse drug event), or caught after some harm but before further or worsening harm (ameliorated adverse drug event). Pairs of physician and pharmacist reviewers confirmed recovered medication errors and assessed their potential for harm. Observers were unblinded and clinical outcomes were not evaluated. RESULTS We conducted 226 observation sessions spanning 787 hours and observed pharmacists reviewing 17,320 medications ordered or administered to 6,471 patients. We identified 504 recovered medication errors, or 7.8 per 100 patients and 2.9 per 100 medications. Most of the recovered medication errors were intercepted potential adverse drug events (90.3%), with fewer mitigated adverse drug events (3.9%) and ameliorated adverse drug events (0.2%). The potential severities of the recovered errors were most often serious (47.8%) or significant (36.2%). The most common medication classes associated with recovered medication errors were antimicrobial agents (32.1%), central nervous system agents (16.2%), and anticoagulant and thrombolytic agents (14.1%). The most common error types were dosing errors, drug omission, and wrong frequency errors. CONCLUSION ED pharmacists can identify and prevent potentially harmful medication errors. Controlled trials are necessary to determine the net costs and benefits of ED pharmacist staffing on safety, quality, and costs, especially important considerations for smaller EDs and pharmacy departments.

Abstract
Significant pain, activity limitation, and disability in patients with acute and chronic gouty arthritis lower health-related quality of life. Although many effective therapies are available for gouty arthritis, medication errors are common. One goal of therapy is to reduce the frequency of gout flares by lowering serum uric acid. Further, evidence suggests that the quality of care provided to patients with gout may also impact health-related quality of life. This article reviews evidence concerning quality of care and quality of life for patients with gout.

Abstract
Cyclobenzaprine is a tricyclic pharmacologic agent that has enjoyed considerable use since its availability. Most clinical usages have focused on the muscle relaxant properties, the mechanism of action being more recently redefined. Higher orders of the CNS are, nevertheless, affected, and the latter contributes to the spectrum of proclaimed side effects that are otherwise largely anticholinergic in nature. Cyclobenzaprine has a reasonable safety profile and overdoses are not as problematic as those for accepted tricyclic psychotherapeutic agents. Clinical studies have given supportive, albeit not conclusive, evidence for treatment roles in the short-term management of acute neck and back pain, and fibromyalgia. Further and more exacting science is warranted to explore the value of this drug in other neurological and psychiatric contexts.

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 Medication errors contribute to significant morbidity, mortality, and costs to the health system. Little is known about the characteristics of Emergency Department (ED) medication errors. STUDY OBJECTIVE To examine the frequency, types, causes, and consequences of voluntarily reported ED medication errors in the United States. METHODS A cross-sectional study of all ED errors reported to the MEDMARX system between 2000 and 2004. MEDMARX is an anonymous, confidential, de-identified, Internet-accessible medication error-reporting program designed to allow hospitals to report, track, and share error data in a standardized format. RESULTS There were 13,932 medication errors from 496 EDs analyzed. The error rate was 78 reports per 100,000 visits. Physicians were responsible for 24% of errors, nurses for 54%. Errors most commonly occurred in the administration phase (36%). The most common type of error was improper dose/quantity (18%). Leading causes were not following procedure/protocol (17%), and poor communication (11%), whereas contributing factors were distractions (7.5%), emergency situations (4.1%), and workload increase (3.4%). Computerized provider order entry caused 2.5% of errors. Harm resulted in 3% of errors. Actions taken as a result of the error included informing the staff member who committed the error (26%), enhancing communication (26%), and providing additional training (12%). Patients or family members were notified about medication errors 2.7% of the time. CONCLUSION ED medication errors may be a result of the acute, crowded, and fast-paced nature of care. Further research is needed to identify interventions to reduce these risks and evaluate the effectiveness of these interventions.

Abstract
The objective of this study was to examine the prevalence of potentially inappropriate medications (PIMs) and potential adverse drug effects (ADEs) in older adults presenting to the emergency department (ED). This was a prospective observational study of a convenience sample of adults 65 years and older presenting to the ED at an urban, tertiary care hospital. Potentially inappropriate medications were defined according to 2003 Beers criteria. Potential ADEs were defined as either (1) a potential drug-drug interaction, (2) alternative medication likely to cause toxicity or drug interactions, or (3) toxic doses of vitamins or minerals. Of 174 eligible patients, 124 were enrolled. The mean number of medications used per patient was 8.6 (range, 0-20). Thirty six patients (29%, 95% confidence interval, 27%-37%) presented to the ED with at least one PIM. Eight PIMs were prescribed in the ED, representing 16% of all prescriptions in the ED. Potential ADEs meeting the defined criteria were found in 26.6% of patients. A subanalysis of a random sample of charts revealed significant discordance between medication lists obtained by the research assistants and that of the health care providers. Older ED patients are at high risk for use of potentially inappropriate medications and ADEs. This problem may be magnified by inaccurate medication lists obtained by ED providers. A larger multicenter study may help to better define the scope of this problem.

Abstract
BACKGROUND Prescribing of potentially harmful medications has not been well documented in hospitals. OBJECTIVE The objective of the study was to determine the rate of and factors associated with potentially inappropriate medication (PIM) prescribing in a large inpatient sample. DESIGN The study was a retrospective cohort of the period between September 1, 2002, and June 30, 2005. We used multivariable logistic regression to identify patient, physician, and hospital characteristics associated with PIM prescribing. SETTING The study collected data from 384 US hospitals. PATIENTS The sample was composed of patients aged >or=65 years admitted with 1 or more of 7 common medical diagnoses. MEASUREMENTS The percentage of patients prescribed PIMs as defined using a modified Beers list was measured. Multivariable-adjusted odds ratios for PIM use were computed. RESULTS Of the 493,971 patients, 49% received at least 1 PIM, and 6% received 3 or more, most commonly promethazine, diphenhydramine, and propoxyphene. Patient, physician, and hospital characteristics were all associated with PIM use. Patients with myocardial infarction or heart failure were most likely (61% and 52% vs. 46% for pneumonia), men (47% vs. 49% for women) and those in managed care plans (44% vs. 49% for other plans) were less likely, and patients >or=85 years were least likely (42% vs. 53% for patients aged 65-74 years) to receive PIMs (P < .0001 for all comparisons). For high-severity PIMs, internists and hospitalists had similar prescribing rates (33%), cardiologists had a higher rate (48%), and geriatricians had the lowest rate (24%). The proportion of elders receiving PIMs ranged from 34% in the Northeast to 55% in the South, and variation at the individual hospital level was extreme. At 7 hospitals, PIMs were never prescribed. CONCLUSIONS Wide variation in the use of PIMs is associated with hospital and physician characteristics. Care may be improved by minimizing this non-patient-centered variation.

Abstract
OBJECTIVE To test the feasibility and reliability of a tool and methodology for evaluating expert clinicians' perceptions about the application of the Beers criteria in hospice. DESIGN A pilot survey. SETTING A national medication therapy management provider specializing in hospice care. PARTICIPANTS Thirty-five participants from a multidisciplinary panel were invited to complete the survey. They were selected to represent acute, long-term care, and community practice settings with various levels of experience and judgment. INTERVENTION Respondents were asked to complete the survey by rating their agreement or disagreement with the inappropriateness of the medications or medication classes for hospice patients, using a five-point Likert scale from strongly agree (1) to strongly disagree (5), with the midpoint (3) expressing equivocation. MAIN OUTCOME MEASURES Feasibility as measured by the percentage of returned and completed surveys. A secondary aim was to measure inter-rater reliability and response. RESULTS Twenty-four clinicians (69%) completed the survey, including 13 clinical pharmacists, 6 nurses, and 5 physicians. Twenty-nine responses (2%) were furnished by imputation methods. The intraclass correlation for medication inappropriateness for hospice patients was 0.89 (0.81-0.95), indicating "good" inter-rater reliability. Short-acting benzodiazepines, gastrointestinal antispasmodics, anticholinergics, and antihistamines were considered appropriate for use in older hospice patients, but they are considered inappropriate according to the Beers criteria. CONCLUSION We established a viable methodology for evaluating clinician judgment about medication inappropriateness in older hospice patients. Some medications routinely considered to be inappropriate may be appropriate at end of life; different criteria may be needed to determine medication inappropriateness in hospice care.

Abstract
INTRODUCTION Adverse drug events (ADEs) are associated with inappropriate prescribing (IP) and result in increased morbidity, mortality and resource utilisation. We used Beers' Criteria to determine the three-month prevalence of IP in a non-selected community-dwelling population of acutely ill older people requiring hospitalisation. METHODS A prospective, observational study of 597 consecutive acute admissions was performed. Diagnoses and concurrent medications were recorded before hospital physician intervention, and Beers' Criteria applied. RESULTS Mean patient age (SD) was 77 (7) years. Median number of medications was 5, range 0-13. IP occurred in 32% of patients (n = 191), with 24%, 6% and 2% taking 1, 2 and 3 inappropriate medications respectively. Patients taking >5 medications were 3.3 times more likely to receive an inappropriate medication than those taking < or =5 medications (OR 3.34: 95%, CI 2.37-4.79; P<0.001). Forty-nine per cent of patients with inappropriate prescriptions were admitted with adverse effects of the inappropriate medications. Sixteen per cent of all admissions were associated with such adverse effects. CONCLUSION IP is highly prevalent in acutely ill older patients and is associated with polypharmacy and hospitalisation. However, Beers' Criteria cannot be used as a gold standard as they do not comprehensively address all aspects of IP in older people.

Abstract
OBJECTIVES To determine the prevalence and type of suboptimal pharmacotherapy that older veterans discharged from the emergency department (ED) or urgent care clinic (UCC) receive and to examine factors associated with suboptimal pharmacotherapy in this population. DESIGN Retrospective, cohort study. SETTING An academically affiliated Department of Veterans' Affairs (VA) Medical Center. PARTICIPANTS Four hundred twenty-one veterans aged 65 and older who were prescribed a new medication at the time of discharge from the ED or UCC. MEASUREMENTS The primary dependent variable, suboptimal pharmacotherapy, was a composite measure defined as one or more drug-related problems, based on drugs-to-avoid criteria, drug-drug interactions, drug-disease interactions, and failure to satisfy an explicit quality indicator for prescribing or medication monitoring. RESULTS A total of 757 drugs were prescribed to the 421 patients at the time of discharge from the ED or UCC (mean number+/-standard deviation per patient 1.65+/-1.1). The most frequently prescribed medications were nonsteroidal antiinflammatory drugs (n=59), opioid analgesics (n=47), and fluoroquinolone antibiotics (n=46). Overall, 134 (31.8%) subjects were found to have suboptimal pharmacotherapy with regard to their discharge medications; 49 (11.6%) were prescribed a drug to avoid, 53 (12.6%) received a drug that introduced a new drug-drug interaction, 24 (5.7%) were given a drug that introduced a drug-disease interaction, and 74 (17.6%) did not have a quality indicator satisfied (61% of these evaluated prescribing and 39% evaluated medication monitoring). No consistent associations between patient or visit characteristics and suboptimal pharmacotherapy were identified in multivariable models. CONCLUSION A substantial number of older adults discharged from the ED or UCC may be at risk for adverse events due to suboptimal prescribing and inadequate medication monitoring. Further study is needed to examine the relationship between suboptimal pharmacotherapy and adverse clinical outcomes.

Abstract
The objective of this study was to determine the prevalence of potentially inappropriate medication (PIMs) use in older emergency department (ED) patients based on the updated 2002 Beers criteria. This was a retrospective analysis of 352 consecutive ED visits by patients aged 65 years and older. The mean number of medications taken was 8.4 per patient. In the study population, 111 (32%; 95% confidence interval [CI], 27-36) of 352 patients were taking at least 1 PIM at ED presentation. Propoxyphene/acetaminophen (24/352, 7%; 95% CI, 4-10), muscle relaxants (14/352, 4%; 95% CI, 2-7), and antihistamines (12/352, 3%; 95% CI, 2-6) were the most common PIMs. Among 101 of 193 patients discharged home from the ED with a new prescription, 13 (13%; 95% CI, 6-19) were also given PIMs. The most common PIMs were propoxyphene/acetaminophen (3/101; 95% CI, 1-8), diazepam (3/101; 95% CI, 1-8), cyclobenzaprine (2/101, 2%; 95% CI, 0-7), and diphenhydramine (2/101, 2%; 95% CI, 0-7). Outpatient PIM use in older ED patients is highly prevalent. Further education is needed regarding prescribing practices in this population group.

Abstract
OBJECTIVES To determine the prevalence of inappropriate prescribing, defined by applying modified Beers' criteria, and to examine the influence of the Pharmaceutical Benefits Scheme (PBS), Australia's national scheme for subsidising medicines, on inappropriate prescribing. METHODS Cross-sectional survey of nursing home records, including 7-days data from medication charts. SETTING Fiveteen randomly selected nursing homes (998 residents) in Southeast Queensland and Northern New South Wales, Australia. MAIN OUTCOME MEASURES The prevalence of inappropriate prescribing as defined by modified Beers' criteria and its correlation with PBS restrictions. RESULTS 18.5% of residents were ordered one or more inappropriate medications, and 1.5% of residents were ordered two or more. The level of PBS restriction and the percentage of residents ordered a medication were highly correlated (p = -0.87, P < 0.001). Medications in Beers' criteria that were not listed (subsidised) on the PBS were not ordered for any resident. PBS medicines with subsidies restricted to certain populations or indications were ordered for 0% to 0.1% of residents. Dextropropoxyphene, diazepam, amitriptyline and methyldopa were the only medications in Beers' criteria prescribed to more than 0.5% of residents. Dextropropoxyphene was only subsidised for war veterans, with a caution warning of its potential to cause drug dependence, while diazepam, amitriptyline and methyldopa were listed on the PBS without any subsidy restrictions. CONCLUSION Increases in the level of PBS restriction were associated with decreases in the prevalence of inappropriate prescribing, The targeting of drug subsidies to reduce inappropriate prescribing warrants further investigation.

Abstract
Prescription of medicines is a fundamental component of the care of elderly people, and optimisation of drug prescribing for this group of patients has become an important public-health issue worldwide. Several characteristics of ageing and geriatric medicine affect medication prescribing for elderly people and render the selection of appropriate pharmacotherapy a challenging and complex process. In the first paper in this series we aim to define and categorise appropriate prescribing in elderly people, critically review the instruments that are available to measure it and discuss their predictive validity, critically review recent randomised controlled intervention studies that assessed the effect of optimisation strategies on the appropriateness of prescribing in elderly people, and suggest directions for future research and practice.

Abstract
As people age they almost invariably develop diseases which lead to the prescription of drugs – both to prevent disease progression and for symptomatic relief. Unfortunately, drug treatment in later life is also problematic. There is a dearth of evidence on the efficacy of drugs in people over the age of 80, and members of this age group are at highest risk of adverse drug reactions (ADR).

Abstract
BACKGROUND AND OBJECTIVE Drug therapy is necessary to treat acute illness, maintain current health and prevent further decline. However, optimizing drug therapy for older patients is challenging and sometimes, drug therapy can do more harm than good. Drug utilization review tools can highlight instances of potentially inappropriate prescribing to those involved in elderly pharmacotherapy, i.e. doctors, nurses and pharmacists. We aim to provide a review of the literature on potentially inappropriate prescribing in the elderly and also to review the explicit criteria that have been designed to detect potentially inappropriate prescribing in the elderly. METHODS We performed an electronic search of the PUBMED database for articles published between 1991 and 2006 and a manual search through major journals for articles referenced in those located through PUBMED. Search terms were elderly, inappropriate prescribing, prescriptions, prevalence, Beers criteria, health outcomes and Europe. RESULTS AND DISCUSSION Prescription of potentially inappropriate medications to older people is highly prevalent in the United States and Europe, ranging from 12% in community-dwelling elderly to 40% in nursing home residents. Inappropriate prescribing is associated with adverse drug events. Limited data exists on health outcomes from use of inappropriate medications. There are no prospective randomized controlled studies that test the tangible clinical benefit to patients of using drug utilization review tools. Existing drug utilization review tools have been designed on the basis of North American and Canadian drug formularies and may not be appropriate for use in European countries because of the differences in national drug formularies and prescribing attitudes. CONCLUSION Given the high prevalence of inappropriate prescribing despite the widespread use of drug-utilization review tools, prospective randomized controlled trials are necessary to identify useful interventions. Drug utilization review tools should be designed on the basis of a country's national drug formulary and should be evidence based.

Abstract
BACKGROUND Inappropriate medication prescribing is a significant problem among older adults that may contribute to increased morbidity and mortality as well as increased costs of care. The development of specific lists of medications that are considered potentially inappropriate for older adults, such as the Beers criteria (BC), make it relatively easy to study prescribing practices in large numbers of patients. OBJECTIVE The goal of this study was to determine how frequently adverse drug events (ADEs) in the acute care setting are related to BC medications and to determine if BC medication prescribing is significantly associated with the occurrence of ADEs and other negative outcomes in older hospitalized adults. METHODS This was a retrospective review of patients aged > or =75 years admitted to 2 adult internal medicine services over 18 months (March 2000-August 2001). Data regarding general demographic and clinical information were collected; this information included place of residence before admission and at discharge; medications at admission, during the hospital stay, and at discharge; ADEs; length of stay; and in-hospital mortality Patient medical records were used to determine the occurrence of ADEs. RESULTS : A total of 389 patients (68.9% female; mean age, approximately 79 years) were included. Of these 389 eligible patients, 107 (27.5%) were prescribed a total of 116 BC medications, and 124 (31.9%) experienced a total of 131 ADEs. Only 9.2% (12/131) of the ADEs were attributed to medications listed among the BC. After controlling for covariates, prescription of a BC medication was not significantly associated with experiencing an ADE (adjusted odds ratio [OR], 1.51; 95% CI, 0.98-2.35; P = 0.064), length of stay (adjusted OR, 1.03; 95% CI, 0.64-1.63; P = 0.91), discharge to higher levels of care (adjusted OR, 1.39; 95% CI, 0.82-2.34; P = 0.22), or in-hospital mortality (adjusted OR, 1.49; 95% CI, 0.77-2.92; P = 0.24). CONCLUSIONS Interventions targeted specifically at BC medications would have seemingly done little to change the risk of ADEs in this population. Interventions that are more comprehensive than the BC are necessary to reduce the risk of ADEs and the associated morbidity and mortality in acute care of the elderly.

Abstract
OBJECTIVES To ascertain and analyse the drug consumption of the immobile elderly, as well as the number of potentially inappropriate medications (PIM). DESIGN Cross-sectional study. SETTING Fourteen rural primary care centres. PARTICIPANTS Non-institutionalised immobile patients, older than 64 years were selected by systematic sampling. PRINCIPAL MEASUREMENTS Review of patients' medicine cabinets and noting the daily doses and current number of drugs, as well as the origin of the prescription. Identification of PIM (Beers criteria). RESULTS One-hundred forty-three homes visits were made. The mean age was 81.3+/-7.9 years, of whom 74.8% were women. The most common drugs were: analgesics (9.2%), antacids (7.1%), nitrites-calcium antagonists (6.5%), non-steroidal anti-inflammatories (5.0%), and angiotensin converting enzyme inhibitors (4.7%). The percentage of patients who took more than 4 drugs was 76.1%. A PIM was taken by 35% of the elderly. The most common were: long-acting tranquilisers (41.5%), hypnotics (13.8%), digoxin (13.8%), indomethacin (7.7%), and antispasmodics (6.1%). In the majority of cases, the prescribing of the PIM was made by the family doctor (77.7%). Women took significantly more inappropriate drugs than men (0.50+/-0.72 vs to 0.25+/-0.50; P=.001) and those on multiple medication more than those not on multiple medication (0.50+/-0.73 vs 0.31+/-0.52; P=.008). CONCLUSIONS The prevalence of inappropriate therapy in the immobile elderly is high, therefore an effort must be made to reduce it. Procedures directed towards increasing the quality of prescribing could improve the state of health and quality of life of these patients.

Abstract
The majority of patients with gout are cared for by primary care physicians. Although both the physician and patient may easily recognize the acute arthritis of gout, errors in selecting the most appropriate medication and proper dose are common. The clinical stages of gout include asymptomatic hyperuricemia, intermittent gouty arthritis, and chronic tophaceous gout. Treatment of gout is usually considered after the first attack of arthritis, typically podagra. The aims of treatment are to alleviate the pain and inflammation associated with acute attacks, prevent future attacks, and decrease uric acid levels. Confusion frequently arises because certain medications such as colchicine may have dual purposes: to treat an acute attack and to suppress future attacks. The purpose of this management update is to provide practical advice about prescribing the proper medication considering both treatment goals and patient comorbidities.

Abstract
BACKGROUND AND OBJECTIVE Inappropriate drug use is one of the risk factors for adverse drug reactions in the elderly. We hypothesised that, in elderly patients, geriatricians are more aware of potentially inappropriate medications (PIMs) and may replace or stop PIMs more frequently compared with internists. We therefore evaluated and compared the prevalence of PIMs as well as anticholinergic drug use throughout hospital stay in elderly patients admitted to a medical or geriatric ward. METHODS In this retrospective cross-sectional study, 800 patients aged > or =65 years admitted to a general medical or geriatric ward of a 700-bed teaching hospital in Switzerland during 2004 were included. PIMs were identified using the Beers criteria published in 2003. The prevalence of anticholinergic drug use was assessed based on drug lists published in the literature. RESULTS The prevalence of use of PIMs that should generally be avoided was similar in medical and geriatric inpatients both at admission (16.0% vs 20.8%, respectively; p = 0.08) and at discharge (13.3% vs 15.9%, respectively; p = 0.31). In contrast to medical patients, the reduction in the prevalence of use of PIMs between admission and discharge in geriatric patients reached statistical significance (p < 0.05). Overall, the three most prevalent inappropriate drugs/drug classes were amiodarone, long-acting benzodiazepines and anticholinergic antispasmodics. At admission, the prevalence of use of PIMs related to a specific diagnosis was not significantly different between patients hospitalised to a medical or a geriatric ward (14.0% vs 17.5%, respectively; p = 0.17), as compared with the significant difference evident at hospital discharge (11.7% vs 23.7%, respectively; p < 0.001). This was largely because of a higher prescription rate of platelet aggregation inhibitors in combination with low-molecular-weight heparins and benzodiazepines in patients with a history of falls and syncope. The proportions of patients taking anticholinergic drugs in medical and geriatric patients at admission (13.0% vs 17.5%, respectively; p = 0.08) and discharge (12.2% vs 16.5%, respectively; p = 0.10) were similar. CONCLUSION Inappropriate drug use as defined by the Beers criteria was common in both medical and geriatric inpatients. Compared with internists, geriatricians appear to be more aware of PIMs that should generally be avoided, but less aware of PIMs related to a specific diagnosis, and of the need to avoid anticholinergic drug use. However, the results of this study should be interpreted with caution because some of the drugs identified as potentially inappropriate may in fact be beneficial when the patient's clinical condition is taken into consideration.

Abstract
OBJECTIVE To examine healthcare outcomes associated with Beers' criteria of inappropriate medication use based on a literature review. DATA SOURCES A search of MEDLINE, International Pharmaceutical Abstracts, and Cumulative Index to Nursing and Allied Health Literature was conducted to identify articles published from October 1991 to October 2006. The following key words were used: Beers, inappropriate, medication, drug, use, prescribing, and elderly. A manual search was also conducted using the references listed in the articles identified through the database search. STUDY SELECTION AND DATA EXTRACTION Studies that examined the impact or outcomes of Beers' criteria of inappropriate medication use (1991, 1997, and 2003 critera) were selected. Each article was examined for study setting, data source, study sample, study design, criteria, analysis and covariates, type of healthcare outcome, and study findings. Of 235 articles retrieved, 18 presented studies that examined healthcare outcomes associated with inappropriate medication use based on Beers' criteria. Specifically, setting-specific evidence as well as overall evidence was examined from the selected studies. The review considered evidence of association if more than 50% of the findings were statistically significant. DATA SYNTHESIS Most of the 18 studies evaluated were retrospective cohort studies involving patients 65 years of age or older from diverse healthcare settings. In community settings, there was no evidence of association with respect to mortality and other healthcare use, and evidence regarding quality of life and costs was inconclusive. However, inappropriate medication use was associated with hospitalization measures in community elderly. In nursing homes, there was no evidence of association with mortality and the association with hospitalization measures was inconclusive. In hospitals, there was inconclusive evidence to make any generalizations. Across healthcare settings, inappropriate medication use was associated with adverse drug reactions and costs but not with other outcome measures. CONCLUSIONS There is evidence that Beers' criteria of inappropriate medication use is associated with adverse healthcare impact in the community-dwelling elderly. With increasing use of Beers' criteria as quality-of-care measures, there is a need to strengthen the predictive validity of these criteria in all healthcare settings.

Abstract
AIM To study the occurrence of adverse drug reactions (ADRs) linked to inappropriate medication (IM) use in elderly people admitted to an acute medical geriatric unit. METHODS All the elderly people aged > or = 70 years admitted to the acute medical geriatric unit of Limoges University hospital (France) over a 49-month period were included, whatever their medical condition. For all the patients, clinical pharmacologists listed the medications given before admission and identified the possible ADRs. The appropriateness of these medications and the causal relationship between drugs (either appropriate or not) and ADRs were evaluated. RESULTS Two thousand and eighteen patients were included. The number of drugs taken was 7.3 +/- 3.0 in the patients with ADRs and 6.0 +/- 3.0 in those without ADRs (P < 0.0001). Sixty-six percent of the patients were given at least one IM prior to admission. ADR prevalence was 20.4% among the 1331 patients using IMs and 16.4% among those using only appropriate drugs (P < 0.03). In only 79 of the 1331 IM users (5.9%) were ADRs directly attributable to IMs. The IMs most often involved in patients with ADRs were: anticholinergic antidepressants, cerebral vasodilators, long-acting benzodiazepines and concomitant use of two or more psychotropic drugs from the same therapeutic class. Using multivariate analysis, after adjusting for confounding factors, IM use was not associated with a significant increased risk of ADRs (odds ratio 1.0, 95% confidence interval 0.8, 1.3). CONCLUSION Besides a reduction in the number of drugs given to the elderly, a good prescription should involve a reduction in the proportion of IMs and should take into consideration the frailty of these patients.

Abstract
BACKGROUND Older adults may have decreased homeostatic reserve, have multiple chronic diseases, and take multiple medications. Therefore, they are at risk for adverse outcomes after receiving a drug that exacerbates a chronic disease. OBJECTIVES The aims of this study were to compile a list of clinically important drug-disease interactions in older adults, obtain the consensus of a multidisciplinary panel of geriatric health care professionals on these interactions, and determine the prevalence of these interactions in a sample of outpatients. METHODS This analysis included a 2-round modified Delphi survey and cross-sectional study. Possible drug-disease interactions in patients aged > or =65 years were identified through a search of the English-language literature indexed on MEDLINE and International Pharmaceutical Abstracts (1966-July 2004) using terms that included drug-disease interaction, medication errors, and inappropriate prescribing. Nine health care professionals with expertise in geriatrics (2 geriatricians, 7 geriatric clinical pharmacist specialists) were selected based on specialty training and continuing clinical work in geriatrics, academic appointments, and geographic location. The panel rated the importance of the potential drug-disease interactions using a 5-point Likert scale (from 1 = definitely not serious to 5 = definitely serious). Consensus on a drug-disease interaction was defined as a lower bound of the 95% CI > or =4.0. The prevalence of drug-disease interactions was determined by applying the consensus criteria to a convenience sample of frail older veterans at hospital discharge who were enrolled in a health services intervention trial. RESULTS The panel reached consensus on 28 individual drug-disease interactions involving 14 diseases or conditions. Overall, 205 (15.3%) of the 1340 veterans in the sample had > or =1 drug-disease interaction. The 2 most common drug-disease interactions were use of first-generation calcium channel blockers in patients with congestive heart failure and use of aspirin in patients with peptic ulcer disease (both, 3.7%). CONCLUSIONS A survey of multidisciplinary geriatric health care professionals resulted in a concise consensus list of clinically important drug-disease interactions in older adults. Further research is needed to examine the impact of these drug-disease interactions on health outcomes and their applicability as national measures for the prevention of drug-related problems.

Abstract
Three recently published Institute of Medicine reports, Hospital-Based Emergency Care: At the Breaking Point, Emergency Medical Services: At the Crossroads, and Emergency Care for Children: Growing Pains, examined the current state of emergency care in the United States. They concluded that the emergency medicine system as a whole is overburdened, underfunded, and highly fragmented. These reports did not specifically discuss the effect the aging population has on emergency care now and in the future and did not discuss special needs of older patients. This report focuses on the emergency care of older patients, with the intent to provide information that will help shape discussions on this issue.

Abstract
BACKGROUND AND OBJECTIVE Potentially inappropriate medication use is a major safety issue in the elderly and may cause a substantial proportion of drug-related hospital admissions. Hospitalisation could result in a change in the quantity and type of drugs, but its effect on potentially inappropriate drug use is still unknown. The aim of this study was to estimate the potentially inappropriate medication prevalence in patients > or =70 years of age at admission to and at discharge from an acute medical geriatric unit, and to identify the factors associated with no longer being a potentially inappropriate drug user at hospital discharge. METHODS A prospective drug surveillance study was undertaken in 2018 elderly patients (> or =70 years of age) admitted to an acute medical geriatric unit in Limoges University Hospital, France. Prescribing patterns were established at admission and at discharge. Potentially inappropriate medication use was evaluated according to a list derived from the Beers criteria and adapted to French practice. "To be no longer a potentially inappropriate drug user at discharge" was defined as using at least one potentially inappropriate medication at admission and not using it at discharge. RESULTS The numbers of drugs used at admission/discharge were 6.2 +/- 3.1/5.4 +/- 2.5. The prevalence of potentially inappropriate medication use decreased from 66% (95% CI 63.8, 68.0) at admission to 43.6% (95% CI 41.3, 45.9) at discharge. At discharge, 535 subjects were no longer potentially inappropriate medication users. Multivariate analysis showed that no longer being a potentially inappropriate medication user was associated with the number of drugs used (4-6 drugs vs < or =3 odds ratio [OR] 1.20; 95% CI 0.86, 1.68; 7-9 drugs vs < or =3 OR 1.37; 95% CI 0.97, 1.93; > or =10 drugs vs < or =3 OR 1.64; 95% CI 1.10, 2.44), age (80-89 years vs 70-79 years OR 1.38; 95% CI 1.03, 1.85; > or =90 years vs 70-79 years OR 1.69; 95% CI 1.22, 2.83), cerebral vasodilator use (OR 2.87; 95% CI 2.31, 3.57), analgesic use (OR 1.54; 95% CI 1.06, 2.25) and concomitant use of psychotropic drugs of the same therapeutic class (OR 1.94; 95% CI 1.29, 2.92). CONCLUSION Hospitalisation in geriatric services results in a reduction in potentially inappropriate medication use. Improved pharmacological education of practitioners, especially with regard to drug adverse effects, is desirable to improve management of geriatric patients.

Abstract
The purpose of this article is to assist emergency physicians in selecting safe and effective drug therapy for seniors. Because safer alternatives exist, medications on the Beers list of potentially inappropriate medications should generally be avoided. We also review risks associated with several classes of medications: nonsteroidal anti-inflammatory drugs, benzodiazepines, and anticholinergic medications. They are associated with adverse outcomes when taken by older adults and should be used with caution. We also address the use of opioid medications in seniors. Although they are not without risk, opioids are generally safe with slow titration, precautions, and a bowel regimen to prevent constipation. Prescribers should also consider the need for estimating creatinine clearance when prescribing medications that require dosage adjustment in the setting of renal insufficiency. Two areas in need of research are identifying the proper dosing and safety of medications in seniors and prescribing with electronic decision support to assist in prescribing decisions.

Abstract
STUDY OBJECTIVE To investigate the relationship between two widely used, generic health-related quality of life (HRQOL) measures, Short Form-12 (SF-12) and EuroQol's EQ-5D, and potentially inappropriate drug use in an elderly cohort. DESIGN Longitudinal retrospective cohort study. DATA SOURCE Medical Expenditure Panel Survey, panel 5. PARTICIPANTS Respondents aged 65 years or older. MEASUREMENTS AND MAIN RESULTS Participants with potentially inappropriate drug use were identified by using National Drug Codes based on the Beers updated criteria. The dependent variable, HRQOL, was measured by using self-reported scores on the SF-12 (physical component summary, mental component summary, and global rating of health) and the EQ-5D (index and visual analog scale). The HRQOL data were regressed onto scores for potentially inappropriate drug, age, sex, number of prescriptions, race, comorbidity, and previous HRQOL. Regression analysis revealed statistically significant models for all five HRQOL equations (adjusted R2=26.50-53.83%, p<0.0001). However, potentially inappropriate drug use was not a significant predictor of HRQOL in any of the models tested. Previous HRQOL, as measured by using the SF-12 (global, physical component summary, and mental component summary) and the EQ-5D (index and visual analog scale), was a significant predictor of HRQOL; number of prescriptions was also a significant predictor of HRQOL, as measured by using the SF-12 (global and physical component summary) and the EQ-5D (index and visual analog scale). CONCLUSION The results supported others showing that a significant proportion of the elderly receive care that is potentially harmful and not supported by evidence-based practice. Use of a disease-specific HRQOL scale may be more responsive to measuring the impact of potentially inappropriate drugs on patients' HRQOL.
