The Medicare Readmissions Reduction Program penalizes hospitals with higher than expected readmission rates after discharge for congestive heart failure (CHF). This exploratory study analyzed whether categorizing readmissions by event severity might have implications for the program. The authors used the 5% MedPAR (Medicare Provider and Analysis Review) data for 2008 to 2014 and ranked 1820 hospitals based on all readmissions, readmissions for CHF, short-stay CHF readmissions, and readmissions for severe CHF with evidence of cardiogenic shock. Ranking hospitals based on severe CHF readmissions changes their relative rank order significantly compared to counting all readmissions. If confirmed in the full Medicare data, the finding could inform the design of the Readmission Reduction Program.
