Key result
High performing hospitals had proportionately fewer 30-day readmissions without differences in readmission diagnoses and timing compared to lower performing hospitals.
Why the study?
Do high performing hospitals have a different distribution of readmission diagnoses and timing compared to lower performing institutions in Medicare beneficiaries?

Broad readmission strategies may outperform targeted ones; leaves open causal drivers versus confounding in observational Medicare data.

Do high performing hospitals have a different distribution of readmission diagnoses and timing compared to lower performing institutions in Medicare beneficiaries?
High performing hospitals achieve lower readmission rates globally rather than by reducing specific readmission diagnoses or altering readmission timing, suggesting the benefit of broad readmission reduction strategies.
Dharmarajan et al. (2013) conducted a cohort in Heart failure, acute myocardial infarction, or pneumonia (n=2,944,970). High hospital performance (low 30-day risk standardized readmission rates) vs. Average or low hospital performance was evaluated on Distribution of readmission diagnoses and timing within 30 days. High performing hospitals had proportionately fewer 30-day readmissions without differences in readmission diagnoses and timing compared to lower performing hospitals.
