For this study, researchers accessed data from MedAssurant’s Medical Outcomes Research for Effectiveness and Economics Registry, which contains more than 5.2 billion healthcare events from 77 million unique de-identified individuals.
The researchers discovered the unadjusted 30-day readmission rate for Medicare Advantage patients was 14.5 percent from 2006-2008, compared to a 36.5 percent 30-day readmission rate for Medicare fee-for-service patients in the same time period. This trend held true after adjusting for risk and demographic factors. Specifically, the adjusted 30-day readmission rate for Medicare Advantage patients was 13-20 percent lower than Medicare fee-for-service rates.
