Regional systems of care demonstration project

Background:Up to 50% of patients fail to meet ST-segment–elevation myocardial infarction (STEMI) guideline goals recommending a first medical contact–to–device time of <90 minutes for patients directly presenting to percutaneous coronary intervention–capable hospitals and <120 minutes for transferred patients. We sought to increase the proportion of patients treated within guideline goals by organizing coordinated regional reperfusion plans. Methods:We established leadership teams, coordinated protocols, and provided regular feedback for 484 hospitals and 1253 emergency medical services (EMS) agencies in 16 regions across the United States. Results:Between July 2012 and December 2013, 23 809 patients presented with acute STEMI (direct to percutaneous coronary intervention hospital: 11 765 EMS transported and 6502 self-transported; 5542 transferred). EMS-transported patients differed from self-transported patients in symptom onset to first medical contact time (median, 47 versus 114 minutes), incidence of ...
