Comparison of Systemic Inflammatory Response Syndrome and quick Sequential Organ Failure Assessment scores in predicting bacteremia in the emergency department.

Abstract

AimThe emergency department requires simple and useful clinical indicators to identify bacteremia. This retrospective study explored the Systemic Inflammatory Response Syndrome (SIRS) and quick Sequential Organ Failure Assessment (qSOFA) scores for predicting bacteremia.MethodsBetween April and September 2017, we assessed blood cultures of 307 patients in our emergency department. We calculated the SIRS and qSOFA scores for these patients and evaluated their correlation with bacteremia.ResultsOf 307 patients, 66 (21.5%) had bacteremia, 237 (77.2%) were SIRS‐positive, and 123 (40.0%) were qSOFA‐positive. The sensitivity and specificity of the SIRS score for predicting bacteremia were 87.9% and 25.7%, respectively. The sensitivity and specificity of the qSOFA score were 47.0% and 61.8%, respectively. Multivariate analysis revealed that body temperature (odds ratio, 2.16; 95% confidence interval, 1.22–3.84; P = 0.009) and blood pressure (odds ratio, 2.72; 95% confidence interval, 1.39–5.35; P = 0.004) significantly associated with bacteremia.ConclusionsThe SIRS score was a more sensitive indicator than the qSOFA score for predicting bacteremia.
