Sepsis was associated with nearly 20% of all global deaths, and the majority of sepsis cases occurred in low- or middle-income countries [1]. In 2017, the World Health Organization recommended actions to reduce the global burden of sepsis [2]. Sepsis has been defined as acute life-threatening organ dysfunction due to dysregulation of host responses to Background: Some variables of the Sequential Organ Failure Assessment (SOFA) score are not routinely measured in sepsis patients, especially in countries with limited resources. Therefore, this study was conducted to evaluate the accuracy of the modified SOFA (mSOFA) and compared its ability to predict mortality in sepsis patients to that of the original SOFA score.
Methods
Sepsis patients admitted to the medical intensive care unit of Songklanagarind Hospital between 2011 and 2018 were retrospectively analyzed. The primary outcome was all-cause in-hospital mortality.
Results
A total of 1,522 sepsis patients were enrolled. The mean SOFA and mSOFA scores were 9.7±4.3 and 8.8±3.9, respectively. The discrimination of the mSOFA score was significantly higher than that of the SOFA score for all-cause in-hospital mortality (area under the receiver operating characteristic curve, 0.891 [95% confidence interval, 0.875–0.907] vs. 0.879 [0.862–0.896]; P<0.001), all-cause intensive care unit (ICU) mortality (0.880 [0.863–0.898] vs. 0.871 [0.853–0.889], P=0.01) and all-cause 28-day mortality (0.887 [0.871–0.904] vs. 0.874 [0.856–0.892], P<0.001). The ability of mSOFA score to predict all-cause in-hospital and 28-day mortality was higher than that of the SOFA score within the subgroups of sepsis according to age, sepsis severity and serum lactate levels. The mSOFA score was demonstrated to have a performance similar to the original SOFA score regarding the prediction of mortality in sepsis patients with cirrhosis or hepatic dysfunction.
Conclusions
The mSOFA score was a good alternative to the original SOFA core in predicting mortality among sepsis patients admitted to the ICU.
