Compared with nonranked hospitals, top-ranked hospitals have lower 30-day mortality but similar or higher readmission rates for cardiovascular conditions, according to a study published online Nov. 28 in JAMA Cardiology.
David E. Wang, M.D., from Brigham and Women's Hospital in Boston, and colleagues conducted a cross-sectional study involving 3,552 U.S. hospitals to examine whether US News & World Report top-ranked hospitals for cardiology and heart surgery perform better than nonranked hospitals on mortality rates and readmission measures.
The researchers found that compared with 3,502 nonranked hospitals, the 50 top-ranked hospitals had lower 30-day mortality rates for acute myocardial infarction (AMI; 11.9 versus 13.2 percent; P < 0.001), heart failure (0.5 versus 11.9 percent; P < 0.001), and coronary artery bypass grafting (CABG; 2.3 versus 3.3 percent; P < 0.001). Compared with nonranked hospitals, the 50 top-ranked hospitals had similar readmission rates for AMI (16.7 versus 16.5 percent; P = 0.64) and CABG (14.1 versus 13.7 percent; P = 0.15) and higher rates for heart failure (21 versus 19.2 percent; P < 0.001). Compared with nonranked hospitals, the top-ranked hospitals had higher patient satisfaction (3.9 versus 3.3; P < 0.001).
"It is possible that top-ranked and nonranked hospitals have focused substantial resources on reducing readmissions rather than mortality rates given the financial push of the Hospital Readmission Reduction Program, which resulted in generally similar readmission rates but disparate mortality rates between these hospital groups," the authors write.
