Under the Centers for Medicare and Medicaid Service Hospital Readmissions Reduction Program, hospitals are subject to nonpayment if patients with certain medical conditions are readmitted. Research supports the effectiveness of this program in decreasing readmissions and some have argued for expansion to a hospital-wide readmission measure. Using Medicare claims data, investigators concluded that transitioning to a hospital-wide readmission measure would lead to greater penalties for safety-net hospitals compared to other hospitals, a concern that has been raised with regard to Medicare's Hospital-Acquired Condition Program.
