Abstract
BACKGROUND: How quickly percutaneous coronary intervention is performed in patients with ST-elevation myocardial infarction (STEMI) is a quality measure, reported as door-to-balloon (D2B) time. OBJECTIVES: To explore factors affecting STEMI performance in six hospitals in one healthcare system. METHODS: This was a retrospective chart review of clinical features and D2B times. Predictors for D2B times were identified using multivariate linear regression. RESULTS: The median D2B time for all six hospitals was 63 minutes and all hospitals surpassed the minimal recommended percentage of patients achieving D2B time ≤90 minutes (87.8%vs75%,p<0.001). Patient confounders adversely affect D2B times (+21.5 minutes, p<0.001). Field ECG/activation with emergency department (ED) transport (-22.0 minutes) or direct cardiac catheterization laboratory (CCL) transport (-27.3 minutes) was superior to ED ECG/activation (p<0.001). CONCLUSION: Field ECG/STEMI activation significantly shortened D2B time. To improve D2B time, hospital and Emergency Medical Service collaboration should be advocated to increase field activation and direct patient transportation to CCL.
