Readmission rates after passage of the hospital readmissions reduction program


CLINICAL QUESTION: Did hospitals receiving the highest penalties for readmissions have accelerated improvement in this metric after passage of Medicare Hospital Readmissions Reduction Program (HRRP)?

BACKGROUND: Medicare passed the HRRP to incentivize reductions in readmission rates. The impact of penalties on relative hospital improvement rates remains unknown.

Study Design: Retrospective pre-post analysis.

SETTING: Query of national Medicare Provider Analysis and Review files.

SYNOPSIS: 2,868 hospitals were identified as candidates for analysis and were stratified into four risk groups based on penalty size under HRRP: highest-performing, average-performing, low-performing, and lowest-performing. The primary outcomes were hospital-specific, 30-day, all-cause risk-standardized readmission rates (RSRRs) for patients discharged with acute MI, HF, or pneumonia. The investigators separated data into a pre-law period and post-law period. They fitted a logistic regression model to pre-law RSRRs and developed a piecewise linear model on post-law RSRRs with pre-law data as the dependent variable. All hospital groups had reductions in RSRRs, with the lowest quartile demonstrating greatest improvement.

BOTTOM LINE: HRRP has resulted in reductions in RSRRs with greatest improvement in hospitals with lowest pre-law performance.
