Changes In End-Of-Life Care In The Medicare Shared Savings Program

摘要

End-of-life care is often overly aggressive and inconsistent with patients' preferences. Although end-of-life care could therefore be a natural target for accountable care organizations (ACOs) in their efforts to reduce spending, identifying and curbing wasteful care for patients at high risk of death may be challenging. To date, the impact of ACOs on end-of-life care has not been quantified. Using fee-for-service Medicare claims through 2015 and a difference-in-differences approach, we found evidence of some changes in end-of-life care associated with providers' participation in the Medicare Shared Savings Program among both decedents and patients at high risk of death. Although generally suggestive of less aggressive care, most effects were small and inconsistent across cohorts of ACOs entering the program in different years. This suggests that ACOs have not yet substantially altered end-of-life care patterns and that additional incentives, time, or both may be needed. Alternatively, curbing wasteful end-of-life care might not be a viable source of substantial savings under population-based payment models.
