Prognostic Performance of SOFA, qSOFA, and SIRS in Kidney Transplant Recipients Suffering from Infection: A Retrospective Observational Study

Yun-Xia Chen et al. Adv Ther. 2020 Mar.

Abstract

Introduction: The prognostic performance of scoring systems for illness severity in infectious kidney transplant recipients (KTRs) is rarely reported. We investigated the ability of the scores for the quick Sequential Organ Failure Assessment (qSOFA), Sequential Organ Failure Assessment (SOFA) and Systemic Inflammatory Response Syndrome (SIRS) to predict in-hospital mortality, intensive care unit (ICU) admission and mechanical ventilation (MV) requirement.

Methods: This was a second analysis of a retrospective observational study. Scores for SIRS, SOFA and qSOFA were calculated upon hospitalization (infection onset was before hospitalization) or on the day of infection onset (infection episodes were during hospitalization). The primary outcome was in-hospital mortality. The secondary outcomes were ICU admission and MV requirement. Binary logistic regression and area under the receiver operating characteristic curve (AUC) were employed to assess prognostic performance.

Results: A total of 161 infectious episodes occurred in 97 KTRs. Forty patients (41%) experienced more than one episode. The SOFA score was available in 161 infections, and scores for qSOFA and SIRS were available in 160 infections. The SIRS score was not different between KTRs with opposite outcomes. The qSOFA score was higher in infections necessitating MV. The SOFA score was significantly higher in the deceased, those needing ICU admission, MV, and for those with positive etiology results. The SOFA score was the only independent predictor of in-hospital mortality, ICU admission, and MV requirement, and the AUCs were 0.879, 0.815, and 0.784, respectively. The optimum cutoff value of predicting the three outcomes was SOFA score ≥ 3.

Conclusions: The SOFA score (but not those for SIRS and qSOFA) independently predicted in-hospital mortality, ICU admission, and MV requirement in infectious KTRs.
