Prognostic Accuracy of the Quick Sequential Organ Failure Assessment Score and National Early Warning Scores in mortality rate of the Non-Traumatic Patients

Abstract

Background: The current study aimed to evaluate the predictive value of mortality in patients admitted to the Intensive Care Unit (ICU) through the emergency department and based on Quick Sequential Organ Failure Assessment (qSOFA), National Early Warning Score (NEWS) and NEWS2 criteria.

Methods: In this cross-sectional study, all patients referred to the emergency department with a need of admission to ICU for any reason, were evaluated. Demographic data such as age and sex were recorded for data collection. Also, the main diagnosis, length of stay and hospitalization outcome along with data related to qSOFA, NEWS and NEWS2 indices were included in the researcher's checklist.

Results: Of 89 included patients, 52 (58.4%) were male and 37 (41.6%) were female, with mean age of 60.25±20.8. Our findings indicated that qSOFA is a good predictor for mortality in non-traumatic patients so that qSOFA has 48% sensitivity and 100% specificity in the diagnosis of mortality in non-trauma patients. NEWS also has a sensitivity of 72% and a specificity of 71.4% in the diagnosis of non-traumatic mortality. And NEWS2 has 72% sensitivity and 78.6% specificity in non-traumatic mortality diagnosis.

Conclusion: Our findings suggested that the sensitivity and specificity of qSOFA, NEWS and NEWS2 in predicting the mortality of non-traumatic patients who were admitted in emergency departments and hospitalized in ICU, are high and reliablen.
