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.
