A Randomized Clinical Trial of Outpatient Geriatric Evaluation and Management

Abstract

OBJECTIVES: To measure the effects of outpatient geriatric evaluation and management (GEM) on high‐risk older persons' functional ability and use of health services. DESIGN: Randomized clinical trial. SETTING: Ambulatory clinic in a community hospital. PARTICIPANTS: A population‐based sample of community‐dwelling Medicare beneficiaries age 70 and older who were at high risk for hospital admission in the future (N = 568). INTERVENTION: Comprehensive assessment followed by interdisciplinary primary care. MEASUREMENTS: Functional ability, restricted activity days, bed disability days, depressive symptoms, mortality, Medicare payments, and use of health services. Interviewers were blinded to participants' group status. RESULTS: Intention‐to‐treat analysis showed that the experimental participants were significantly less likely than the controls to lose functional ability (adjusted odds ratio (aOR) = 0.67, 95% confidence interval (CI) = 0.47–0.99), to experience increased health‐related restrictions in their daily activities (aOR = 0.60, 95% CI = 0.37–0.96), to have possible depression (aOR = 0.44, 95% CI = 0.20–0.94), or to use home healthcare services (aOR = 0.60, 95% CI = 0.37–0.92) during the 12 to 18 months after randomization. Mortality, use of most health services, and total Medicare payments did not differ significantly between the two groups. The intervention cost $1,350 per person. CONCLUSION: Targeted outpatient GEM slows functional decline.
