Objective To investigate the estimated values of sequential organ failure assessment (SOFA) and quick SOFA (qSOFA) for diagnosis and prognosis in patients with sepsis according to the new diagnostic criteria in Sepsis 3.0.Methods A retrospective study was conducted.All the clinical data were collected from patients with definite diagnosis of infection and they were admitted into the Intensive Care Unit (ICU) of Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical University from July 2014 to June 2016.The patients' gender,age,infectious location,respiratory rate (RR),oxygenation index (PaO2/FiO2),Glasgow coma scale (GCS),total bilirubin (TBil),platelet count (PLT),serum creatinine (SCr),serum lactate level,etc.general data on admission were collected to carry out SOFA and qSOFA scorings.And then the septic patients in accord with the diagnostic criteria of Sepsis 3.0 were screened out.According to outcome after admission,the septic patients were divided into survival group and death group,and the differences in diagnosis and in estimation value of prognosis between SOFA scoring and qSOFA scoring were assessed as SOFA group and qSOFA group.Results From 545 septic patients enrolled,189 septic patients consistent with the diagnostic criteria of Sepsis 3.0 were selected.In SOFA scoring group,the morbidity of septic patients was 34.68％,while in qSOFA scoring group,it was 15.96％,the difference between the two groups being statistically significant (P ＜0.01).The mortality was significantly lower in SOFA scoring group than that in qSOFA scoring group [28.04％ (53/189)vs.42.53％ (38/87),P ＜ 0.05].The mortality of qSOFA scoring group was about 1.52 times that of SOFA scoring group.On the aspect of scoring,in patients with SOFA scoring the score of death group was significantly higher than that in survival group (8.74 ± 0.417 vs.7.10 ± 0.235,P ＜ 0.01);in the patients with qSOFA scoring,the score in death group compared with that in survival group showed uo statistical significant difference (2.32 ± 0.48 vs.2.16 ± 0.37,P ＞ 0.05).On the aspect of laboratory indexes,the levels of GCS score in death group was significantly lower than that in the survival group (8.15 ± 0.67 vs.12.48 ± 0.36),blood lactate level in death group was significantly higher than that in the survival group (mmol/L:8.55 ± 4.66 vs.2.31 ± 0.16,P ＜ 0.01);the PaO2/FiO2,TBil,PLT and SCr showed no significant differences between the two groups (all P ＞ 0.05).Conclusions The new diagnostic criteria (Sepsis 3.0) can be used for diagnosis of sepsis in ICU.Compared with qSOFA scoring,the SOFA scoring is more suitable to be used for diagnosis and predicting prognosis of septic patients in ICU;SOFA scoring,GCS scoring and serum lactate level can be applied to estimate outcome of septic patients.
