Door-to-Needle Time in Myocardial Infarction: Small Steps, Huge Dividends

Abstract

The Himachal Pradesh acute coronary syndrome registry highlighted a prehospital delay of 780 min. Additional door-to-needle time delay by 1 h increases the hazard ratio of death by 20%. We conducted a retrospective (group 1) and a prospective (group 2) analysis of 63 patients each to measure the impact of a fast-track protocol in the emergency department (ED) on the door-to-needle time in ST-elevation myocardial infarction (STEMI). The fast-track protocol involved zero cost to the hospital and saved 63 precious door-to-needle minutes for patients with STEMI. Thrombolysis in ED can save 33 precious minutes wasted in shifting patients to the coronary care unit. Keywords: Acute coronary syndrome, Quality improvement
