Stroke Nurse Triage: Effects on Time Metrics at a Regional Stroke Center.

Optimization of time metrics in the management of acute stroke is a priority. Nurses with special training in stroke management may contribute to enhanced delivery of care. This study analyzes the effects of initiating a nurse-led stroke triage program at a regional stroke center on time metrics of acute stroke.In retrospective review, stroke metrics 25 months prior to the start of the triage program and 23 months after the start of the program were analyzed, including time from arrival to: emergency department assessment, neurologist assessment, head computed tomography (CT) scan, start of tissue plasminogen activator (tPA) administration, and puncture for mechanical thrombectomy.The study included 1,019 patients presenting with symptoms of acute stroke. Significant decrease was found between means for the time measures of arrival to emergency department (ED) physician assessment (pre-program: 6.2 minutes, post-program: 5.7 minutes, p= 0.0036), and CT start (pre-program: 21.3 minutes, post-program: 19.8 minutes, p= 0.0001). Time from arrival to ED physician assessment and CT start showed an increase in the proportion of cases meeting goal times: ED physician assessment increased from 82 percent to 84.4 percent of cases meeting the goal time (p= 0.3543), and CT start increased from 55.3 percent to 63.2 percent (p= 0.0481) of cases meeting the goal time. Significant increase was found between means for time from arrival to neurologist assessment (pre-program: 11.6 minutes, post-program: 17.1 minutes, p= 0.0015), and the proportion of cases meeting the goal time for arrival to neurologist assessment decreased (88.8 percent pre-program, 75.8 percent post-program). No significant differences were found for times from arrival to tPA administration and mechanical thrombectomy, or between Modified Rankin Scores (mRS) at discharge.Certain time-sensitive metrics of acute stroke care were improved after implementation of the stroke nurse triage program, particularly those related to immediate patient assessment within the ED. Time metrics related to the direct administration of stroke therapies were unaffected, indicating the need for recognition of additional factors affecting timely stroke management. Incorporating specially trained stroke nurses in acute stroke management may be an important component in efforts to improve time metrics of acute stroke.
