The Supply of Hospital Care to Minority and Low-Income Communities and the Hospital Readmission Reduction Program

In: Medical care research and review, Band 78, Heft 1, S. 77-84

Abstract

To determine if the Centers for Medicare and Medicaid Services Hospital Readmission Reduction Program reduced hospital discharges for penalized conditions in minority and low-income communities, we used hospital discharge data for 2006 and 2013 from Arizona, California, Colorado, Florida, New Jersey, New York, North Carolina, and Wisconsin and readmission data from the Medicare Hospital Compare website. Negative binomial regression was used for 6,564 zip codes for each year to estimate the association between the expected penalty for an excess readmission in the hospital service area and the number of hospital discharges for penalized conditions (acute myocardial infarction, congestive heart failure, and pneumonia) for zip codes. The results showed that the expected penalty for excess readmissions had a negative association with the number of discharges for acute myocardial infarction, congestive heart failure, and pneumonia. The negative association increased with the percentage of minority residents but not with the poverty rate.
