The "door-to-needle blitz" in acute myocardial infarction: the impact of a CQI project.
A continuous quality improvement (CQI) project was conducted at Soroka Medical Center in Beer-Sheva, Israel, in an effort to identify and address causes of delays in thrombolytic therapy in patients arriving at a high-volume (160,000 patients per year) emergency department with acute myocardial infarction and thereby reduce the "door-to-needle time" (DTNT). The study had four phases: preintervention survey, peri-intervention process redesign, postintervention evaluation, and follow-up evaluation. CQI TEAM: The CQI team followed a seven-step protocol: problem definition, present-state screening, factors analysis, solution development, outcome evaluation, standardization, and conclusions. ⋯ Results suggest that the 30-minute DTNT suggested by the American College of Cardiology/American Heart Association is appropriate for patients with a clear diagnosis and no contraindications for thrombolysis, but when the risk-benefit ratio of thrombolytic therapy raises concerns, a 45- to 60-minute DTNT may still be acceptable. Further CQI projects should address technical triage of simple cases and clinical estimation of risk-benefit ratio in complicated patients.
