Abstract

This study compares risk-standardized mortality rates (RSMRs) of patients with acute myocardial infarction among tertiary A (typically, advanced urban hospitals with more than 800 beds), tertiary B (urban hospitals with more than 500 beds), and secondary A hospitals (rural and urban hospitals with less than 500 beds) in Shanxi, China. In all, 43 500 acute myocardial infarction inpatient records from 93 hospitals were included. Hierarchical logistic regression was used to estimate RSMRs, and Dunn’s post hoc test was used to make pairwise comparisons of RSMR between hospital levels. It was found that the median RSMRs of secondary A hospitals were significantly lower than those of tertiary A and tertiary B hospitals (at 1% and 10% significance level, respectively), while there was no significant difference between the median RSMRs in tertiary A and tertiary B hospitals. The reasons for significant disparity in quality of care among different hospital levels requires further exploration.
