Rahmatinejad Z, et al. - The Sequential Organ Failure Assessment (SOFA) and modified SOFA (mSOFA) scores are risk stratification systems which include respiratory, coagulatory, liver, cardiovascular, renal, and neurologic systems to measure the overall severity of acute disorder in the intensive care unit. Researchers assessed the value of these scores at arrival for predicting in-hospital mortality in the emergency department (ED). They included all adult patients with an Emergency Severity Index (ESI) of 1–3 in the ED of Imam Reza Hospital, northeast of Iran from March 2016 to March 2017. As per outcomes, in predicting in-hospital mortality, the scores showed fair discrimination and good calibration when applied to ED.
