INTRODUCTION: Prehospital stroke scales have been developed to identify anterior large vessel occlusion (LVO) in acute ischemic stroke (AIS) patients for direct transport to thrombectomy-capable hospitals. However, its performance in a Vietnamese population remains unknown. We aimed to evaluate the predictive value of the Rapid Arterial oCclusion Evaluation (RACE) scale for LVO detection in patients with ischemic stroke presenting within 24 h in Vietnam. METHODS: This was a prospective study of patients with AIS admitted at People's 115 Hospital between May 2022 and October 2022. All patients were assessed with the RACE scale with five items: facial palsy (scored 0-2), arm motor function (0-2), leg motor function (0-2), gaze (0-1), and aphasia or agnosia (0-2). LVO was diagnosed by CTA or MRA. Receiver operating characteristic curve, sensitivity, specificity, and accuracy of the RACE scale were analyzed to evaluate its predictive value for LVO. RESULTS: There were 318 patients included. LVO was detected in 121/318 patients (37.6%). The higher the RACE score, the higher the proportion of patients with LVO (p < 0.001). Receiver operating characteristic curves showed capacity to predict LVO of the RACE scale with an area under the curve (AUC) of 0.767. The optimal RACE cutoff was ≥5 with sensitivity = 0.68, specificity = 0.79, positive predictive value = 0.67, negative predictive value = 0.80, and overall accuracy = 0.75. RACE ≥5 had higher sensitivity and same specificity for detecting LVO in AIS patients within 6-h versus 6-24-h window (AUC = 0.79 vs. 0.75, sensitivity = 0.74 vs. 0.65, specificity = 0.79 vs. 0.80, accuracy = 0.77 vs. 0.74). CONCLUSIONS: The RACE scale is a simple tool that can accurately identify AIS patients with LVO. This tool may be useful for early detection of LVO patients and should be validated in the prehospital setting in Vietnam.
