PREVENTIVE SERVICES FOR THE ELDERLY - WOULD COVERAGE AFFECT UTILIZATION AND COSTS UNDER MEDICARE

Objectives. This study was undertaken to determine whether adding a be nefit for preventive services to older Medicare beneficiaries would af fect utilization and costs under Medicare. Methods. The demonstration used an experimental design, enrolling 4195 older, community-dwelling Medicare recipients. Medicare claims data for the 2 years in which the preventive visits occurred were compared for the intervention (n = 21 05) and control (n = 2090) groups. Monthly allowable charges for Part A and Part B services and number of hospital discharges and ambulatory visits were compared. Results. There were no significant differences in the charges between the groups owing to the intervention, although total charges were somewhat lower for the intervention group even when the cost of the intervention was included. Charges for both groups ro se significantly as would be expected for an aging population. A compa nion paper describes a modest health benefit. Conclusions. There appea rs to be a modest health benefit with no negative cost impact. This fi nding gives an early quantitative basis for the discussion of whether to extend Medicare benefits to include a general preventive visit from a primary care clinician.
