A combination of C-reactive protein and quick sequential organ failure assessment (qSOFA) score has better prognostic accuracy than qSOFA alone in patients with complicated intra-abdominal infections

Abstract

INTRODUCTION: Complicated intra-abdominal infections (cIAIs) remain a serious challenge because of their unacceptably high mortality rates. Among different prognostic scoring systems quick-sequential organ failure assessment (qSOFA) score is the most recent. However, as mortality predictor in surgical patients, qSOFA showed lack of sensitivity. The aim of this study was to find prognostic superiority of our new qSOFA-CRP score in patients with cIAIs. MATERIALS AND METHODS: We retrospectively analyzed 78 patients presented to ED and admitted to Department of Surgical Diseases between January 2017 and October 2018 with diagnosis cIAIs. CRP levels, qSOFA score and systemic inflammatory response syndrome (SIRS) were established at admission. We analyzed area under receiver operating characteristics (AUROC) curves of SIRS, qSOFA and qSOFA-CRP and performed a comparison to explore their prognostic values. RESULTS: = .0009). The new qSOFA-CRP score ≥2 points showed excellent specificity (91.4%) and the highest sensitivity in comparison to qSOFA ≥2 and SIRS ≥2 (60% vs. 35% vs. 40%) for mortality prediction. CONCLUSIONS: qSOFA-CRP score showed better prognostic value than quick-SOFA alone in patients with cIAIs.
