Early warning score predicts acute mortality in stroke patients.

摘要: Objectives Clinical deterioration and death among patients with acute stroke are often preceded by detrimental changes in physiological parameters. Systematic effective tools to identify at risk of early enough intervene therefore needed. The aim the study was investigate whether aggregate weighted track trigger system warning score (EWS) can be used as a simple observational tool predict mortality population stroke. Materials methods Patients admitted Copenhagen University Hospital, Nordsjaellands Denmark, from May September 2012 were enrolled retrospective cohort (n = 274). Vital signs measured immediately after admission consistently during hospitalization period. Based on vital signs, single composite EWS calculated. Death within 30 days outcome. Area under receiver operating characteristics curve (AUROC) Kaplan–Meier computed examine prognostic validity EWS. Results A total 24 (8.8%) died 30 days. performance high for both (AUROC 0.856; 95% CI 0.760–0.951; P-value < 0.001) maximal 0.949; 0.919–0.980; P-value < 0.001). Mortality rates lowest 0–1 (2%) highest EWS ≥ 5 (63%). Conclusions Early is valid identifying dying stroke. Readily available parameters converted score, which guide nurses physicians clinical decision making resource allocation.
