Accuracy of SOS Score for Predicting In-hospital Mortality of Emergency Patients
Keywords:
SOS score, Emergency department, mortalityAbstract
Search Out Severity (SOS) score was widespread use to predict poor outcomes for the patients, As the same in Modified Early Warning Score (MEWS) and National Early Warning Score II (NEWS II) too. However, the research to determine the accuracy for use in emergency departments needs further study. The objective of this research is for studying the accuracy of the SOS score in predicting mortality in emergency patients compared with MEWS and NEWS. This research was a cross-sectional study. 412 Emergency patients, who were aged more than 15 years and had an indication for admission to the hospital from December 14, 2020, to March 25, 2021, were recruited for this study. The physiologic parameters of the patients were recorded in case record form. Data were analyzed by STATA version 14 about the accuracy of SOS, MEWS, and NEWS II for predicting 28-day in-hospital mortality. Presentation of the statistics by using sensitivity, specificity, and area under the curve (AUROC). The results revealed a 17.48% for mortality rate. AUC of SOS score, NEWS II and MEWS were 0.793, 0.789, and 0.759 respectively. The optimal cut-off point for the SOS score for predicting 28-day mortality was greater than or equal to 3 points, and the sensitivity and specificity were 86.11%, and 60.59% respectively. The SOS score was good for predicting 28-day mortality, close to the MEWS and NEWS II, with the optimal cut-off point greater than or equal to 3 points.
