Abstract TP401: Impact of Vital Signs and Neurological Assessments After Alteplase for Acute Stroke

Abstract

Background: Vital signs and neurologic assessments are currently performed using the schedule utilized during the clinical trials which led to the approval of alteplase for acute stroke. These assessments can be disruptive to patients and represent a considerable staffing and infrastructural demand. While the goal of this approach is to improve outcomes by rapidly detecting actionable changes, its impact has been questioned. Despite its widespread use there has been limited systematic review regarding its influence on outcomes. Purpose: This project’s aim was to determine the impact of these assessments by conducting a retrospective review at our large, urban, comprehensive stroke center. We sought to evaluate the rate of compliance with established guidelines, and assess its correlation with patient outcomes. Methods: This retrospective review of patients receiving alteplase for acute stroke was approved by our institutional review board. A total of 130 patients were identified during 2018. Data was collected from the electronic medical record and The Get with the Guidelines database. Results: Our institutional guideline includes a total of 36 vital signs and 24 neurological assessments during first 24-hours after alteplase administration, for a total of 60 assessments. 63% of patients had full compliance with all 60 assessments. The discharge modified Rankin scale (mRS) for those with full compliance was 2.35 versus 2.31 for patients without 100% compliance (p>0.05; NS). There was less compliance with vital signs compared to neurological assessments (73.8% versus 76.9%). Conclusions: The majority of patients were complaint with all assessments however a notable portion missed at least one assessment, occurring more frequently with vital signs. Full compliance with all assessments was not associated with improved mRS.
