A randomized clinical trial of outpatient geriatric evaluation and management

OBJECTIVES: To measure the effects of outpatient geriatric evaluation and m anagement (GEM) on high-risk older persons' functional ability and use of h ealth services. DESIGN: Randomized clinical trial. SETTING: Ambulatory clinic in a community hospital. PARTICIPANTS: A population-based sample of community-dwelling Medicare bene ficiaries age 70 and older who were at high risk for hospital admission in the future (N = 568). INTERVENTION: Comprehensive assessment followed by interdisciplinary primar y 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 participa nts were significantly less likely than the controls to lose functional abi lity (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 (a OR = 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. Mo rtality, use of most health services, and total Medicare payments did not d iffer significantly between the two groups. The intervention cost $1,350 pe r person. CONCLUSION: Targeted outpatient GEM slows functional decline.
