Abstract 3967: Interdisciplinary Emergency Department (ED) Acute Stroke Case Review Decreases Door to Needle (DTN) Times
Background: Stroke is one of the leading causes of death and the leading cause of disability in the United States. Previous studies suggest that the quicker that intravenous tissue plasminogen activator (IV tPA) is administered, the safer and more effective it is, thus lowering the odds of in hospital mortality and symptomatic intracranial hemorrhage.
Objective: To investigate whether implementing a process oriented, interdisciplinary bimonthly review of acute ischemic stroke cases would decrease DTN times and ultimately lead to the consistent administration of IV tPA within 60 minutes of arrival to the ED.
Methods: To decrease the IV tPA DTN times, the stroke team at United Hospital in St. Paul, Minnesota developed a new ED stroke review process in July 2010 to analyze each acute ischemic stroke case. The cases were compiled into a document that contained time specific goals for each step of the acute stroke code process. Members of the stroke team would review the data prior to the meeting and if there was a delay (ie outside of the timed goal for lab result) in their department they would investigate the cause. At the meeting, the team would identify best practice efficiencies and barriers, leading to changes in the process. Formal follow up with each department and key learnings were sent to staff on a monthly basis.
Results: In 2010, there were 82 patients admitted with an acute ischemic stroke, within 3.5 hours from time last known well, and 28 patients received IV tPA 34% (28/82). From January to June, 2011 there have been 46 acute ischemic stroke patients and 18 patients received IV tPA (18/46) 39%. The mean DTN time was 88 minutes in 2010 vs. 70 minutes in 2011; mean age was 64 vs. 66.5; % female was 46% (13/28) vs. 67% (12/18); median NIH Stroke Scale was 6 vs. 6. The percentage of patients treated with IV tPA within 60 minutes of hospital arrival increased from 21.4% (6/28) in 2010 to 50% (9/18) from January to June 2011 (p=0.022).
Conclusions: The DTN times significantly decreased after the implementation of a process oriented, interdisciplinary ED acute stroke case review. The percentage of patients receiving IV tPA within 60 minutes increased from 21.4% to 50% over a 18 month period.
