- Abstract
Objectives: To determine whether frail older adults, based on a deficit accumulation index (DAI), are at greater risk of adverse outcomes after discharge from the emergency department (ED)., Design and Setting: Secondary analysis of data from the Medicare Current Beneficiary Survey., Participants: One thousand eight hundred fifty-one community-dwelling Medicare fee-for-service enrollees, aged 65 and older who were discharged from the ED between January 2000 and September 2002., Measurements: The primary dependent variable was time to first adverse outcome, defined as repeat outpatient ED visit, hospital admission, nursing home admission, or death, within 30 days of the index ED visit., Results: Time to first adverse outcome was shortest in individuals with the highest number of accumulated deficits. The frailest participants were at greater risk of adverse outcomes after ED discharge than those who were least frail (hazard ratio (HR)=1.44, 95% confidence interval (CI)=1.06-1.96). The frailest individuals were also at higher risk of serious adverse outcomes, defined as hospitalization, nursing home admission, or death (HR=1.98, 95% CI=1.29-3.05). In contrast, no association was detected between degree of frailty and repeat outpatient ED visits within 30 days (HR=1.06, 95% CI=0.73-1.54)., Conclusion: The DAI as a construct of frailty was a robust predictor of serious adverse outcomes in the first 30 days after ED discharge. Frailty was not found to be a major determinant of repeat outpatient ED visits; therefore, additional study is needed to investigate this particular type of health service use by older adults.

- Abstract
Background: Adverse drug reactions (ADR) negatively impact life quality and are sometimes fatal. This study examines the incidence and predictors of all and preventable ADRs in frail elderly persons after hospital discharge, a highly vulnerable but rarely studied population., Methods: The design was a prospective cohort study involving 808 frail elderly persons who were discharged from 11 Veteran Affairs hospitals to outpatient care. The main outcome measure was number of ADRs per patient as determined by blinded geriatrician and geropharmacist pairs using Naranjo's ADR algorithm. For all ADRs (possible, probable, or definite), preventability was assessed. Discordances were resolved by consensus conferences., Results: Overall, 33% of patients had one or more ADRs for a rate of 1.92 per 1000 person-days of follow-up. The rate for preventable ADRs was 0.71 per 1000 person-days of follow-up. Independent risk factors for all ADRs were number of medications (adjusted [Adj.] hazard ratio [HR], 1.07; 95% confidence interval [CI], 1.05-1.10 per medication), use of warfarin (Adj. HR, 1.51; 95% CI, 1.22-1.87), and (marginally) the use of benzodiazepines (Adj. HR, 1.23; 95% CI, 0.95-1.58). Counterintuitively, use of sedatives and/or hypnotics was inversely related to ADR risk (Adj. HR, 0.14; 95% CI, 0.04-0.57). Similar trends were seen for number of medications and warfarin use as predictors of preventable ADRs., Conclusions: ADRs are very common in frail elderly persons after hospital stay, and polypharmacy and warfarin use consistently increase the risk of ADRs.

- Abstract
Objectives: To determine the prevalence and predictors of unnecessary drug use at hospital discharge in frail elderly patients., Design: Cross-sectional., Setting: Eleven Veterans Affairs Medical Centers., Participants: Three hundred eighty-four frail older patients from the Geriatric Evaluation and Management Drug Study., Measurements: Assessment of unnecessary drug use was determined by the consensus of a clinical pharmacist and physician pair applying the Medication Appropriateness Index to each regularly scheduled medication at hospital discharge. Those drugs that received an inappropriate rating for indication, efficacy, or therapeutic duplication were defined as unnecessary., Results: Forty-four percent of patients had at least one unnecessary drug, with the most common reason being lack of indication. The most commonly prescribed unnecessary drug classes were gastrointestinal, central nervous system, and therapeutic nutrients/minerals. Factors associated (P<.05) with unnecessary drug use included hypertension (adjusted odds ratio (AOR)=0.61, 95% confidence interval (CI)=0.38-0.96), multiple prescribers (AOR=3.35, 95% CI=1.16-9.68), and nine or more medications (AOR=2.24, 95% CI=1.25-3.99)., Conclusion: A high prevalence of unnecessary drug use at discharge was found in frail hospitalized elderly patients. Additional studies are needed to identify predictors and prevalence of unnecessary drug use in nonveteran populations so that interventions can be designed to reduce the problem.

- Abstract
Background: Drugs can improve quality of life for many older people, but they may cause adverse health outcomes (eg, drug-disease interactions) if used inappropriately., Objective: To determine the prevalence of potential drug-disease interactions as defined by explicit criteria and examine associations between sociodemographic and health status variables and potential drug-disease interactions., Methods: The study design was cross-sectional. We evaluated 397 frail elderly inpatients from the Geriatric Evaluation and Management trial conducted at 11 Veterans Affairs Medical Centers. Drug-disease interactions were defined using explicit criteria from consensus expert panels of geriatricians from the US and Canada., Results: Overall, 159 (40.1%) patients had one or more potential drug-disease interaction. The most common potential interactions were calcium-channel blockers and heart failure (12.3%) and beta-blockers and diabetes (6.8%). Multivariable logistic regression analyses revealed that age > or =75 years (adjusted OR 2.43; 95% CI 1.52 to 3.88), being married (adjusted OR 1.77; 95% CI 1.11 to 2.82), comorbidity index defined by Charlson method (adjusted OR 1.19; 95% CI 1.05 to 1.34), and use of multiple prescription drugs (5-8: adjusted OR 4.17; 95% CI 1.96 to 8.88, > or =9: adjusted OR 9.22; 95% CI 4.26 to 19.95), were significantly (p < 0.05) associated with having one or more potential drug-disease interaction., Conclusions: Potential drug-disease interactions are common in hospitalized elderly patients and are related to specific sociodemographic and health status factors. Further research is needed to examine the relationship between health outcomes and drug-disease interactions.

- Abstract
Background: Inappropriate prescribing in frail elderly inpatients has not received as much investigation as in frail elderly nursing home patients., Objective: To determine the prevalence and predictors of inappropriate prescribing for hospitalized frail elderly patients., Methods: The study was conducted at 11 Veterans Affairs Medical Centers and involved a sample of 397 frail elderly inpatients. Inappropriate prescribing was measured by physician-pharmacist pair's consensus ratings for 10 criteria on the Medication Appropriateness Index (MAI). The MAI ratings generated a weighted score of 0-18 per medication (higher score = more inappropriate) and were summed across medications to achieve a patient score., Results: Overall, 365 (91.9%) patients had > or =1 medications with > or =1 MAI criteria rated as inappropriate. The most common problems involved expensive drugs (70.0%), impractical directions (55.2%), and incorrect dosages (50.9%). The most common drug classes with appropriateness problems were gastric (50.6%), cardiovascular (47.6%), and central nervous system (23.9%). The mean +/- SD MAI score per person was 8.9 +/- 7.6. Stepwise ordinal logistic regression analyses revealed that both the number of prescription (adjusted OR 1.28; 95% CI 1.21 to 1.36) and nonprescription drugs (adjusted OR 1.17; 95% CI 1.06 to 1.29) were related to higher MAI scores. Analyses excluding the number of drugs revealed that the Charlson index (adjusted OR 1.62; 95% CI 1.12 to 2.35) and fair/poor self-rated health (adjusted OR 1.15; 95% CI 1.05 to 1.26) were related to higher MAI scores., Conclusions: Inappropriate drug prescribing is common for frail elderly veteran inpatients and is related to polypharmacy and specific health status characteristics.
