Abstract

Background Routine performance measures of primary percutaneous coronary intervention (PCI) within an ST-segment elevation myocardial infarction (STEMI) network are needed to improve care. Objective We evaluated the door-in to door-out (DI-DO) delays at the initial hospitals in STEMI patients as a routine performance measure of the metropolitan STEMI network. Patients and Methods We retrospectively analyzed the DI-DO time from 1,076 patients with acute STEMI who were transferred by ground ambulance to a primary PCI center for primary PCI between 4 October 2014 and 1 April 2019. Correlation analysis between DI-DO times and total ischemia time was performed using Spearman's test. Logistic regression analyses were used to find variables associated with a longer DI-DO time. Results Median DI-DO time was 180 minutes (25th percentile to 75th percentile: 120-252 minutes). DI-DO time showed a positive correlation with total ischemia time ( r = 0.4, p < 0.001). The median door-to-device time at the PCI center was 70 minutes (25th percentile to 75th percentile: 58-88 minutes). Multivariate analysis showed that women patients were independently associated with DI-DO time > 120 minutes (odds ratio 1.55, 95% confidence interval 1.03 to 2.33, p = 0.03). Conclusion The DI-DO time reported in this study has not reached the guideline recommendation. To improve the overall performance of primary PCI in the region, interventions aimed at improving the DI-DO time at the initial hospitals and specific threat for women patients with STEMI are possibly the best efforts in improving the total ischemia time.
