Triage early warning score as the best predictor of in-hospital mortality: a systematic review study

Many patients may experience unexpected clinical deterioration during hospitalization, and the severity of this clinical deterioration is associated with in-hospital mortality. Therefore, an effective triage tool for quick identification of risk factors and in-hospital mortality is essential. Currently, several scoring systems are used to predict clinical deterioration and in-hospital mortality. This study was conducted with the aim of investigating the accuracy of early warning score tools in predicting in-hospital mortality.

  In this review study, the  related  articles searched by using the keywords Early warning score, Triage early warning score, and Inhospital mortality and their persian equivalents in Jahad Daneshgahi Database, Iran Scientific Research Institute, Database of Iranian Journals, Springer, Medline, PubMed, and Google Scholar.

Based on the prisma diagram, 95 articles were found. And according to the aim of the study, 32 related articles were selected. The results showed that the triage early warning score tool is more accurate in predicting in-hospital mortality.

Early warning score systems are useful tools in patient risk management. Meanwhile, triage early warning score has more power in predicting clinical deterioration and in-hospital mortality, considering that age is one of its parameters.
