Abstract

The Medicare Shared Savings Program (Shared Savings Program) is designed to facilitate coordination and cooperation among providers to improve the quality of care for Medicare Fee-For-Service beneficiaries and to reduce unnecessary costs under Tracks 1 and 2. Medicare beneficiaries are preliminarily prospectively assigned to Accountable Care Organizations (ACOs) quarterly and retrospectively assigned annually using a claims-based attribution methodology. We posit that higher Medicare beneficiary turnover among ACOs is associated with less desirable quality scores on health care quality outcomes. This association may reflect beneficiary dissatisfaction as a result of perceived poor care quality. Or, increasing turnover and care quality deterioration may be secondary to ACO market competition. We sought to examine and quantify the relationship between ACO Medicare beneficiary turnover and all-cause hospital readmissions. We expected higher beneficiary turnover to correlate with higher all-cause hospital admissions.
