A cost analysis of self-management programs for people with chronic illness

The soaring cost of health care is a national problem that needs response at multiple levels, including that of the community. Reducing or limiting health care costs through interventions that emphasize the self-management of health may promote broader health care coverage, better quality of health care, and a sense of control over one's health. Therefore, it behooves community psychologists to perform cost analyses when testing interventions for people in a community. The present study investigated the effects of social support and education interventions on psychosocial variables, health status, and health care costs in older people with osteoarthritis. Participants were 363 members of a health maintenance organization (HMO), 60 years of age and older, with osteoarthritis. Participants were randomly assigned to one of three intervention groups (social support, education, or a combination of both) or to a control group. The results indicated that feelings of helplessness decreased in the intervention groups but not in the control group. All groups showed increases in self-efficacy and overall health status. In addition, health care costs increased less in the intervention groups than in the control group. Cost analysis was used to demonstrate that the monetary savings of the intervention greatly outweighed the cost of conducting the intervention. It appears that interventions can limit health care costs while improving health and increasing feelings of control for older people with osteoarthritis. Further, this paper demonstrates how a cost-benefit focus can benefit community studies.
