Summary
Implementing an Autolaunch protocol significantly reduced door-in-door-out (DIDO) times for ST-segment elevation myocardial infarction (STEMI) patients. This quality improvement initiative improved transfer efficiency and patient outcomes.
Area of Science:
- Cardiology
- Quality Improvement Science
Background:
- Timely transfer of ST-segment elevation myocardial infarction (STEMI) patients to percutaneous coronary intervention-capable centers is crucial for optimal outcomes.
- National compliance with the American Heart Association's ≤30-minute door-in-door-out (DIDO) time benchmark for STEMI transfers remains suboptimal.
