Abstract 123: Door To Needle 60, Creative Solutions in Academia

Abstract

Introduction: National guidelines endorse that eligible acute ischemic stroke (AIS) patients should be treated with intravenous tissue plasminogen activator (IV tPA) within 60 minutes of arrival to an emergency department (ED). We participated in the American Heart Association’s Target: Stroke program which successfully reduced door to needle (DTN) times through 10 best practices, but academic hospitals face a unique challenge as junior residents evaluate and manage AIS patients. We hypothesized that a “stroke boot camp” could improve resident efficiency during stroke codes and shorten DTN times through faster stroke code to tPA times. Methods: A neurology resident educational protocol was developed and implemented in April 2013 using a Socratic case-based discussion to emphasize focused history and exam, medication history, and tPA exclusion criteria. We distributed cards with IV tPA risks/benefits and a checklist for tPA exclusion criteria. We compared pre-intervention (January 2010-April 2013) to post-intervention (April 2013-April 2014) patient demographics, comorbidities, resident level, relevant times, and outcomes using appropriate tests. Results: We analyzed 122 consecutive AIS patients treated with IV tPA in our ED during the study period. Pre and post intervention groups did not differ by demographics except gender (p = 0.005). There were no difference in comorbidities, baseline NIHSS, or resident post graduate year (PGY). After the intervention, stroke-code-to-tPA was significantly reduced (75 min vs. 45 min; p < 0.001), whereas door-to-stroke-code (7 min vs. 6 min, p = 0.56) and door-to-CT (18 min vs. 19 min, p = 0.44) did not change. The proportion of patients treated within 60 minutes increased (16.4% vs. 51.4%, P < 0.001) and median DTN time decreased (81 min vs. 60 min P < 0.001) significantly after the intervention. Time reductions were consistent across PGY levels without increased adverse outcomes. Conclusion: Reduction in stroke code-to-tPA times after implementation of a “stroke boot camp” led to a significant reduction in DTN time. Focused neurology resident acute stroke education should be implemented at academic institutions to improve rapid IV tPA administration
