Sources of Hospital Variation in Short-Term Readmission Rates After Percutaneous Coronary Intervention
Key result
Hospital 30-day all-cause readmission rates after PCI varied widely (9.5% to 17.9%), with procedural and postprocedural factors explaining only 10.4% of the between-hospital variance.

Implication
Wide unexplained variation in post-PCI readmission rates persists across hospitals; leaves open the impact of unmeasured hospital characteristics on outcomes.

Population
36,060 patients undergoing PCI at 24 nonfederal hospitals in Massachusetts between 2005 and 2008 who survived to discharge, followed for 30 days.

Exposure
Percutaneous coronary intervention (PCI)

Outcome
30-day, all-cause risk-standardized readmission rates (RSRRs)hard clinical
There is wide variation in 30-day all-cause readmission rates after PCI across hospitals, most of which cannot be explained by identifiable procedural and postprocedural factors.
Cite This Study
Yeh et al. (2012) conducted an observational in Percutaneous coronary intervention (n=36,060). Hospital of treatment vs. Other hospitals was evaluated on 30-day all-cause readmission. Hospital 30-day all-cause readmission rates after PCI varied widely (9.5% to 17.9%), with procedural and postprocedural factors explaining only 10.4% of the between-hospital variance.
