Comparison of different critical illness scores for intensive care unit mortality in patients with gastrointestinal and abdominal tumors
Objective To evaluate the predictive efficacy of sequential organ failure assessment(SOFA),simplified acute physiological scoreⅡ(SAPS-Ⅱ),Oxford acute severity of illness score(OASIS),Logistic organ dysfunction score(LODS),acute physiology scoreⅢ(APS-Ⅲ),and model for end-stage liver disease(MELD)score in predicting the intensive care unit(ICU)mortality among patients with gastrointestinal and abdominal tumors.Methods Patients that met the inclusion criteria with gastrointestinal and abdominal tumors were included from the American Intensive Care Medical Information DatabaseⅢ(MIMIC-Ⅲ),and characteristics of patients between survival and death groups were compared.The receiver operator characteristic curve(ROC curve)of 6 critical illness scores were plotted,area under the curve(AUC)was used to assess performance in predicting ICU mortality.Kaplan-Meier survival curve was drawn to analyze the difference in the cumulative survival rate between patients with SAPS-Ⅱ≤49 and those with SAPS-Ⅱ>49,and patients with APS-Ⅲ≤68 and APS-Ⅲ>68.Results A total of 1 400 patients were enrolled for the final analysis,with 1 233 being survivors and 167 deceased.The ROC curve analysis showed:SAPS-Ⅱ,APS-Ⅲ,OASIS,SOFA,LODS,and MELD scoring systems were all predictive values for ICU prognosis in patients with gastrointestinal and abdominal tumors with AUC values of 0.835,0.831,0.816,0.797,0.788,and 0.729,respectively,among which the AUC of SAPS-Ⅱscore was the largest.Kaplan-Meier survival analysis showed that ICU survival rate in patients with SAPS-Ⅱ≤49 score was significantly higher than that in patients with SAPS-Ⅱ>49 score(Log-Rank:χ2=122.87,P=0.001);ICU survival rate in patients with APS-Ⅲ≤68 score was significantly higher than that in patients with APS-Ⅲ>68 score(Log-Rank:χ2=146.37,P=0.001).Subgroup analysis showed that for patients complicating sepsis,the predicting efficancy of the SPAS-Ⅱscore was superior than other scoring systems.Conclusion SPAS-Ⅱhas better predication for ICU mortality among gastrointestinal and abdominal tumors patients.
