Acute myocardial infarction has been the second leading cause of death in Taiwan. It's a novel issue to evaluate the relationship between the 24-h PCI service model and the outcome of STEMI patients. The objective of this study was to determine the effect of 24-h PCI service model in STEMI patients to improving survival rate. This population-based cohort study included those STEMI patients, older than 18 year-old, who had ever called emergency department from 2012 to 2018. We had two groups of our study participant, one group for STEMI patients with 24-h PCI model and the other group for STEMI patients with non-24-h PCI model. We used the Logistic regression model to analyze the risk of death within 30 days, emergency department (ED) revisits within 3 days, and readmission within 14 days. After the relevant variables were controlled, the risk of death after an ED visit among the patients with STEMI who were sent to hospitals with 24-h PCI services was significantly lower than that among the patients with STEMI who were sent to hospitals without 24-h PCI services (OR 0.85; 95% CI 0.75-0.98). However, the model could not reduce the risk of ER revisits and readmission.
