Application of national early warning score in prognosis of stroke patients in the emergency department / 中国实用护理杂志

ABSTRACT

Objective To discuss the feasibility and applicability in prognosis prediction of t he National Early Warning Score (NEWS) for stroke patients in emergency department through comparing NEWS and modified early warning score(MEWS). Methods 1 195 cases of stroke patients for NEWS and MEWS from May 2013 to June 2015 in emergency centerwere chosen, and were tracked prognosis for 30 days, two score prediction ability were compared. Results When took death as prediction index, the area under the ROC curve of NEWS was AZ=0.906, sensitivity was 84.1%,specificity was 86.1%,best truncated point was 4.5 score; The area under the ROC curve of MEWS was AZ=0.846,sensitivity was 80.5%,specificity was 77.9%,best truncated point was 2.5 score, the difference was statistically significant between them (Z=3.324,P<0.05).It showed that NEWS had higher value than MEWS in prognosis prediction for stroke patients in emergency department. Conclusions NEWS score is a good tool to predict stroke patients in emergency department, which has better value than MEWS.
