Abstract 17432: Specific Care Process Implementation Associated With Improved Reperfusion Times Across Multiple STEMI Networks: Insights From The AHA Mission: Lifeline STEMI Accelerator Program

Introduction: The STEMI Accelerator Program occurred in 16 U.S. metropolitan regions and resulted in more patients receiving timely reperfusion. We assessed whether implementing key care processes was associated with shorter reperfusion times. Methods: Hospitals (n=167 with 23,498 STEMI patients) were surveyed pre- (02/2012) and post- (08/2014) intervention with a standardized care process questionnaire. Survey data were then merged with patient-level clinical data over the same time period. For reperfusion times, hospitals were stratified by whether they implemented a specific process of care, had a pre-existing process, or never implemented the process. Results: Uptake of several care processes increased following intervention: pre-hospital activation (62% to 91% of hospitals; p<0.001), single call transfer protocol from an outside facility (45% to 70%; p<0.001) and emergency department (ED) bypass for both direct presenters via paramedics (48% to 59%; p=0.002) and transfer patients (56% to 79%; p=0.001...
