Comment on "Comparison of different versions of the quick sequential organ failure assessment for predicting in-hospital mortality of sepsis patients"

Dear editor, We have read with great interest the recent article "Comparison of different versions of the quick sequential organ failure assessment for predicting in-hospital mortality of sepsis patients: A retrospective observational study".[1] They showed that the performance of the procalcitonin-enhanced qSOFA (PqSOFA) was similar to that of the qSOFA, and the lactate-enhanced qSOFA (LqSOFA) and the modified qSOFA (MqSOFA) were superior to the qSOFA for predicting in-hospital mortality. Further, they suggested that the MqSOFA should be a candidate for the qSOFA in the emergency department (ED). We congratulate the authors for their contributions. However, we has several concerns about this research.
