The Hospital Readmissions Reduction Program (HRRP), implemented by the Centers for Medicare & Medicaid Services (CMS), imposes a financial penalty on hospitals with higher than average readmission rates for certain conditions. Six years of readmission rates for four conditions included in the HRRP (acute myocardial infarction, chronic obstructive pulmonary disease, congestive heart failure, and pneumonia) and two conditions not included (septicemia and mood disorders) were analyzed to assess the impact of the HRRP. The researchers conclude the HRRP reduced readmission rates for the four targeted conditions, but reductions were not consistent across all categories of patients.
