Abstract:
Background: National guidelines recommend eligible acute stroke patients undergo neuroimaging within 25 min and IV tPA within 60 min. In order to reduce door-to-needle time, we implemented an “ED2CT” virtual group pager which allows ED staff to simultaneously activate the Stroke Team, neuroradiologists, CT technologists, nursing supervisors and pharmacists. Methods: We performed an IRB approved retrospective review of a prospectively acquired cohort of consecutive patients with ischemic stroke presenting to a single tertiary stroke center using our Get With the Guidelines Stroke (GWTG-S) database. We compared patients who received IV tPA within 3 hours of symptom onset pre- (March 2006-April 2008) to post-intervention (September 2008-December 2009) by Wilcoxon or Fisher's exact as appropriate. Results: Overall, there were 56 patients in the pre-intervention and 53 in the post-intervention groups. Patients were 50.5% male, median age was 76 [IQR 63, 85] years, median time to presentation was 50 [IQR 33, 87] min, and median initial NIHSS was 14 [IQR 8, 20]. None of these variables were significantly different between the pre- and post-intervention groups. Implementation of the ED2CT alert was associated with a reduction of 31% in door-to-CT time (29 [22, 40] vs. 20 [16, 29] min; p= 〈 0.001) and 13.5% in door-to needle time (59 [42, 78] vs. 51 [35, 62] min; p=0.02). In addition, there was an increase of 55% in the proportion of patients undergoing CT within 25 min (42.9% vs.66.7 % p=0.01) and 39% in door-to needle within 60 min (51.8% vs. 72.0% p=0.03). Symptomatic intracerebral hemorrhage (sICH) was infrequent among patients receiving IV tPA with or without rescue IA reperfusion (n=109, 8.3%) and those with IV tPA only (n=83, 6.0%); there was a trend in reduced sICH rate post intervention (11.6% vs. 0%; p=0.06). Conclusions: A novel emergency alert system with which the ED attending directly activates multiple members of the acute stroke clinical and imaging team was associated with an improved door-CT time and improved door-tPA time without an increased risk of sICH. This approach aligns acute stroke care activation with trauma and emergency cardiac care and suggests that team-based approaches may be better than specialty -specific responses.
