Key result

Minority-serving hospitals performing CABG were projected to be almost twice as likely to receive readmission penalties compared to non-minority-serving hospitals (61% vs 32%).

Why the study?

Do readmission penalties under the Hospital Readmissions Reduction Program disproportionately affect minority-serving hospitals performing CABG?

Population

National Medicare beneficiaries undergoing coronary artery bypass grafting in 2008 to 2010.

Comparison

Minority-serving hospitals vs Non-minority-serving hospitals

Design

Cohort

Member takes

Implication

May warrant caution expanding HRRP penalties to CABG at minority-serving hospitals; observational data leave open whether risk adjustment equalizes rates.

Yes

Structured PICO

Do readmission penalties under the Hospital Readmissions Reduction Program disproportionately affect minority-serving hospitals performing CABG?

P
Population
255,250 national Medicare beneficiaries undergoing coronary artery bypass grafting across 1,186 hospitals between 2008 and 2010.
E
Exposure
Minority-serving hospitals (defined as hospitals in the top quintile according to proportion of black patients treated)
C
Comparator
Non-minority-serving hospitals (defined as hospitals in the bottom quintile according to proportion of black patients treated)
O
Outcome
Projected readmission penalties according to the Hospital Readmissions Reduction Program formula

Main Result

Absolute Event Rate: 61% vs 32%

Expanding the Hospital Readmissions Reduction Program to cardiac surgery may disproportionately penalize minority-serving hospitals, potentially impacting care for disadvantaged patients.

Shih et al. (2014) conducted an observational in Coronary artery bypass grafting (CABG) (n=255,250). Minority-serving hospital status vs. Non-minority-serving hospital status was evaluated on Projected readmission penalties. Minority-serving hospitals performing CABG were projected to be almost twice as likely to receive readmission penalties compared to non-minority-serving hospitals (61% vs 32%).
