Outcomes of preventive case management among high-risk elderly in three medical groups: a randomized clinical trial

Preventive case management was implemented by Sharp Healthcare of San Diego with the intention of complementing primary care for geriatric patients enrolled in PacifiCare's Secure Horizons Medicare plan. This article presents patient outcomes after 12 months of participation. The program featured an annual screening questionnaire, appointment monitoring, disease education, and self-management support. It used a prospective design, tracking randomly assigned treatment (n= 1,537) and control patient samples (n = 1,542) for 12 months. Outcomes included physical and mental health status; hospital, ER, and nursing home use; hospital days and expenditures among persons having an inpatient stay; and primary care physician visits. Utilization data were obtained from Sharp Healthcare systems and from screening questionnaires. No statistically significant main effects were found, but persons with three or more independent activity of daily living limitations were about half as likely to have a nursing home admission if they were in case management rather than in the control group.
