Improving Door-to-Needle Times for Acute Ischemic Stroke

This is totally pathetic. The goal should be negative DTN time. With an objective diagnosis in the ambulance with no neurologist needed you should be able to deliver tPA before you get to the hospital. If that is not your goal then get the fuck out of the way and let actual leaders get that done.

Abstract

Background—The effectiveness of specific systems changes to reduce DTN (door-to-needle) time has not been fully evaluated. We analyzed the impact of 4 specific DTN time reduction strategies implemented prospectively in a staggered fashion.

Methods and Results—The HASTE (Hurry Acute Stroke Treatment and Evaluation) project was implemented in 3 phases at a single academic medical center. In HASTE I (June 6, 2012 to June 5, 2013), baseline performance was analyzed. In HASTE II (June 6, 2013 to January 24, 2015), 3 changes were implemented: (1) a STAT stroke protocol to prenotify the stroke team about incoming stroke patients; (2) administering alteplase at the computed tomography (CT) scanner; and (3) registering the patient as unknown to allow immediate order entry. In HASTE III (January 25, 2015 to June 29, 2015), we implemented a process to bring the patient directly to CT on the emergency medical services stretcher. Log-transformed DTN time was modeled. Data from 350 consecutive alteplase-treated patients were analyzed. Multivariable regression showed the following factors to be significant: giving alteplase in the CT (32% decrease in DTN time, 95% confidence interval [CI] 38%–55%), stretcher to CT (30% decrease in DTN time, 95% CI 16%–42%), patient registered as unknown (12% decrease in DTN time, 95% CI 3%–20%), STAT stroke protocol (11% decrease in DTN time, 95% CI 1%–20%), and stroke severity (National Institutes of Health Stroke Scale score 6–8: 19% decrease in DTN time, 95% CI 6%–31%; National Institutes of Health Stroke Scale score >8: 27% decrease in DTN time, 95% CI 17%–37%).

Conclusions—Taking the patient to CT on the emergency medical services stretcher, registering the patient as unknown, STAT stroke protocol, and administering alteplase in CT are associated with lower DTN time.
