STRAUMA: A Novel Alert System for a Combined Stroke and Trauma.

Abstract

Cerebrovascular accident (CVA) can lead to traumatic injury. While timely administration of tissue plasminogen activator (tPA) can be lifesaving in CVAs, it is contraindicated with active bleeding. A STRAUMA is a combined stroke and highest-level trauma activation for patients with suspected CVA and signs of trauma. The purpose of this study is to evaluate the impact of the STRAUMA activation on time to CT and patient outcomes. A retrospective review was conducted on adult patients presenting to a Level 1 trauma and comprehensive stroke center with signs of CVA between 01/2019 and 09/2020. Patients who had a STRAUMA activation were compared to patients who had a stroke alert. Five hundred and eighty patients met the inclusion criteria. Of these, 111 had STRAUMA activations and 469 had stroke alerts. There were no differences in age, gender, or anticoagulation use. The STRAUMA group had a higher NIH stroke scale (NIHSS) (11 vs 5, P<.0001). The STRAUMA group had a longer time to CT (23.1 min vs 16.9 min, P<.0001) and a lower rate of tPA (13.5% vs 27.9%, P = .001). Time to tPA and thrombectomy were similar. The STRAUMA group had a 15% rate of traumatic injury with a median injury severity score of 9. Mortality was higher in the STRAUMA group (14.4% vs 6.0%, P = .003). Multivariable logistic regression identified NIHSS and time to CT as predictors of mortality. STRAUMA did not predict mortality. The novel STRAUMA activation allows for an evaluation of both stroke and trauma to facilitate safe and timely administration of lifesaving interventions.
