Background:
Nurses play an integral role in triaging stroke patients. The purpose of this quality improvement initiative was to determine the efficacy of using an emergent large vessel occlusion (ELVO) screening protocol in the emergency department by nursing staff to improve identification of eligible patients as compared with current practice, improving time to endovascular treatment.
Methods:
Retrospective chart review was used to identify 76 patients admitted to a large urban stroke center. Of these, 36 presented during a 4-month period before the implementation of the Stroke Vision, Aphasia, Neglect (Stroke VAN) tool for assessing ELVO risk; 40 patients were admitted during the 4 months after implementation of Stroke VAN.
Results:
The mean door-to-computed tomography angiography scan times were reduced from 119 to 49 minutes (P < .0001) for all patients and reduced from 77 to 27 minutes in a subset of VAN-positive patients.
Conclusion:
Implementation of the VAN screening tool to assess for ELVO was associated with decreased door-to-computed tomography angiography times and more rapid identification of endovascular eligible patients with ischemic stroke.
