Abstract
BACKGROUND: Acute coronary syndrome (ACS) is a life-threatening medical condition that accounts for an annual expenditure of more than $300 billion in the United States. Hospital accreditation has been shown to improve patient and hospital outcomes for various conditions. OBJECTIVES: This study aimed to determine the benefits of hospital accreditation in patients with ACS. METHODS: This nationwide population-based cohort study used Taiwan's National Health Insurance Research Database from 1997 to 2011 (n = 249,354). Multivariable logistic regression was used to analyze the risk of in-hospital events among those treated in accredited and non-accredited hospitals, and to compare outcomes in hospitals before and after accreditation. The effect of accreditation on these events was also stratified by accreditation grade. RESULTS: A total of 823 hospitals were included, of which 2.4% were medical centers, 13.7% were regional hospitals, and 83.8% were district hospitals. The in-hospital mortality [odds ratio (OR), 0.82; 95% confidence interval (CI), 0.79-0.85; p < 0.001] and recurrent acute myocardial infarction (AMI) admission (OR, 0.81; 95% CI, 0.71-0.93; p = 0.003) rates were significantly lower in the after-accreditation group than in the before-accreditation group. There was a substantial and marked decrease in the in-hospital mortality rate after accreditation in 2008. CONCLUSIONS: This cohort study demonstrated that ACS accreditation was associated with better in-hospital mortality and recurrent AMI admission rates in ACS patients.
