Abstract
Kaiser Permanente initiated a two-year demonstration ambulatory case management program in its Ohio region to evaluate five outcomes: perceived health status, functional status, and satisfaction with care, service use, and service costs. Expected results were not consistently obtained for the five outcome measures. Treatment group members did not, however, experience the functional status impairments or decline in health status perceptions reported by the control group during the study period. The unexpected finding that costs were not affected may be attributed to the type of case management intervention used in the demonstration program. This study is broadly applicable to managed care settings facing the challenge of developing programs to minimize the risk for bearing the costs of the Medicare beneficiaries' overall health when all services are not covered. Managed care administrators should be favorably disposed to implementing a case management model with the potential for affecting functional status, the most significant predictor of expensive continuing care for this cohort of Medicare beneficiaries, while working to develop more effective protocols and resource control strategies.
