BackgroundSurvival in older adults has a high variability. The possible association of length of survival with potentially inappropriate medication (PIM) use remains unclear.AimTo examine the four-year survival rate, the prevalence of polypharmacy and PIM use at admission, and the association between the two, in an inception cohort of newly admitted nursing home residentsMethodsData were used from ageing@NH, a prospective observational cohort study in nursing homes. Residents (n = 613) were followed for four years after admission or until death. PIM use was measured at admission, using STOPPFrail. The Kaplan-Meier method was used to estimate survival, using log-rank tests for subgroup analyses. Cox regression analyses was used to explore associations with PIM use and polypharmacy, corrected for covariatesResultsMean age was 84, 65% were females. After one, two, three and four years the survival rates were respectively 79%, 60.5%, 47% and 36%. At admission, 47% had polypharmacy and 40% excessive polypharmacy, 11% did not use any PIMs, and respectively 28%, 29%, and 32% used one, two and three or more PIMs. No difference in survival was found between polypharmacy and no polypharmacy, and PIM use and no PIM use at admission. Neither polypharmacy nor PIM use at admission were associated with mortality.ConclusionResidents survived a relatively short time after NH admission. Polypharmacy and PIM use at admission were relatively high in this cohort, although neither was associated with mortality. 相似文献

The adverse drug reactions caused by potentially inappropriate medications (PIMs) are closely related to emergency department visits and acute hospital admissions in the elderly population. It has been reported that 11.5-14% of community-dwelling elderly patients were prescribed for at least one PIM, but little is known regarding to it in rural Taiwan. The purpose of this study was to evaluate the prevalence and risk factors of PIMs among older patients visiting the outpatient clinic of a community health center in rural Taiwan. In August of 2008, all elderly patients attended the outpatient clinic of a community health center in I-Lan County were enrolled for study. PIMs are evaluated by Beers’ criteria. In total, 327 patients (mean age: 74.8 ± 5.3 years old, 49.5% males) were enrolled, and 27.5% (90/327) of them were prescribed for at least one PIM. The most common PIMs were antihistamines (50.9%) and muscle relaxants (39.0%). In particular, 87.6% of these PIMs were having a high severity potential. Patients had PIMs were significantly older (76.2 ± 6.9 vs. 74.2 ± 6.1 years, p = 0.011), being prescribed for more drugs (3.7 ± 1.4 vs. 2.4 ± 1.7 items, p < 0.001), and more commonly to visit due to acute diseases (64.4% vs. 24.9%, p < 0.001) than those had no PIM. Multiple logistic regression showed that older age (OR = 1.05, 95% CI = 1.00-1.09, p = 0.046), higher number of prescribed medications (OR = 1.66, 95% CI = 1.39-1.98, p < 0.001), and diagnosis of acute diseases (OR = 8.98, 95% CI = 4.71-17.10, p < 0.001) are all independent risk factors for PIMs. In conclusion, the prevalence of PIMs in the outpatient clinic of the community health care center in rural Taiwan was 27.5%. Older age, higher number of prescribed medications and diagnosis of acute diseases are independent risk factors for PIMs in rural Taiwan. 相似文献

ObjectivesTo investigate polypharmacy and potentially inappropriate medications (PIMs) in elderly patients visiting the urology department for lower urinary tract symptoms (LUTS).MethodsWe retrospectively analyzed digital medical records of individuals over the age of 65 who visited the urology department for LUTS. This cross-sectional study was conducted in 10 hospitals located in South Korea, between September 2017 and December 2017. All prescribed medications were analyzed using electronic medical records. The updated 2015 Beers criteria were used to identify and assess the appropriateness of the prescribed drugs in elderly patients.ResultsWe analyzed a total of 2143 patients aged over 65 years from 10 institutions. The mean age was 74.2 ± 6.26 years (65–97), 1634 (76.2%) were men. Patients took a mean of 6.48 ± 2.46 medications (range 0–18), and polypharmacy was found in 1762 patients (82.2%). The number of patients who received PIMs at least once was 1579 (73.7%). The average number of PIMs used per patient was 1.31 ± 1.25 (0–7). PIM use ratio was 18.9 ± 0.15% (0–67%). The number of chronic diseases, and concurrent medication and polypharmacy were predictive factors associated with PIM use.ConclusionOur multi-institutional results show that a substantial proportion of elderly patients took PIMs when visiting the urology department. Factors associated with PIMs were the number of chronic diseases and polypharmacy. Medication use in elderly patients, especially in urology, should be monitored carefully. 相似文献

AimTo study the population-based prevalence of potentially inappropriate medication (PIM) among older individuals with diabetes, and to identify factors associated with their use.MethodsWe used the Quebec Integrated Chronic Disease Surveillance System (QICDSS) database to conduct a population-based cohort study of individuals with diabetes ≥66 years between April 1st, 2014 and March 31st, 2015. PIMs were defined according to the 2015 Beers Criteria. Factors associated with PIM use were identified using robust Poisson regression models. Risk ratios (RR) and 99% confidence intervals (99%CI) were calculated.ResultsMore than half (56%) of the 286,962 older individuals with diabetes used at least one PIM over a year. Benzodiazepines (41%), proton pump inhibitors (27%) and endocrine medication (mainly glibenclamide) (25%) were the most common PIMs used. Factors associated with PIM use included female sex (RR: 1.17; 99%CI: 1.16–1.18), and comorbidities such as schizophrenia (1.48; 1.45–1.51), anxiety disorders (1.34; 1.33–1.35) and Alzheimer's disease (1.14; 1.13–1.25). Risks of using PIMs increased both with increasing comorbidities and number of medications.ConclusionPIM use is highly prevalent among older individuals with diabetes. Interventions to promote optimal medication use should particularly target individuals with comorbidities and polypharmacy who are most vulnerable to adverse drug events. 相似文献

The percentage of the population described as elderly is growing, and a higher prevalence of multiple, chronic disease states must be managed concurrently. Healthcare practitioners must appropriately use medication for multiple diseases and avoid risks often associated with multiple medication use such as adverse effects, drug/drug interactions, drug/disease interactions, and inappropriate dosing. The purpose of this study is to identify a consensus definition for polypharmacy and evaluate its prevalence among elderly outpatients. The authors also sought to identify or develop a clinical tool which would assist healthcare practitioners guard against inappropriate drug therapy in elderly patients. The most commonly cited definition was a medication not matching a diagnosis. Inappropriate was part of definitions used frequently. Some definitions placed a numeric value on concurrent medications. Two common definitions (ie, 6 or more medications or a potentially inappropriate medication) were used to evaluate polypharmacy in elderly South Carolinians (n = 1027). Data analysis demonstrates that a significant percentage of this population is prescribed six or more concomitant drugs and/or uses a potentially inappropriate medication. The findings are 29.4% are prescribed 6 or more concurrent drugs, 15.7% are prescribed one or more potentially inappropriate drugs, and 9.3% meet both definitions of polypharmacy used in this study. The authors recommend use of less ambiguous terminology such as hyperpharmacotherapy or multiple medication use. A structured approach to identify and manage inappropriate polypharmacy is suggested and a clinical tool is provided. 相似文献
