目的 构建重症肺部感染相关脓毒症预后不良的预测模型,并评估模型的预测效能。方法 收集2018年4月-2021年2月三门峡市中心医院收治的165例重症肺部感染相关脓毒症患者临床资料,其中28 d治疗后生存58例(预后良好组)、死亡107例(预后不良组),采用Logistics回归分析法构建预后不良的预测模型,Hosmer-Lemeshow检验评估模型的拟合度,受试者工作特征(ROC)曲线评估模型的预测效能。结果 与预后良好组比较,预后不良组患者合并急性肾损伤占比较高(P<0。05);白细胞计数、尿素氮、血肌酐、总胆红素、谷草转氨酶、谷丙转氨酶、C-反应蛋白、降钙素原、急性生理学与慢性健康状况Ⅱ(APACHE Ⅱ)评分、全身感染相关性器官功能衰竭评价(SOFA)评分均升高(P<0。05);前白蛋白及24 h乳酸清除率降低(P<0。05);Logistic回归分析结果显示,合并急性肾损伤及APACHE Ⅱ评分、SOFA评分均为重症肺部感染相关脓毒症预后不良独立危险因素(P<0。05),24 h乳酸清除率为独立保护因素(P<0。05);多元Logistic回归方程获得重症肺部感染相关脓毒症预后不良的预测模型,Hosmer-Lemeshow检验显示模型拟合度较好(x2=12。691,P=0。124),ROC曲线分析显示模型的预测效能较高[曲线下面积(AUC)值为0。881,95%CI:0。814~0。949]。结论 应用Logistic回归分析法构建预测模型能综合评估重症肺部感染相关脓毒症的不良预后,模型拟合度满意,预测效能较高,可为脓毒症诊疗提供指导数据。
Prediction model for poor prognosis of patients with severe pulmonary infection-related sepsis and its predictive efficiency
OBJECTIVE To establish the prediction model for poor prognosis of the patients with severe pulmonary infection-related sepsis and assess the predictive efficiency of the model.METHODS The clinical data were collect-ed from 165 patients with severe pulmonary infection-related sepsis who were treated in Sanmenxia Central Hospi-tal from Apr 2018 to Feb 2021 and were divided into the favorable prognosis group with 58 cases and the poor prognosis group with 107 cases according to the survival status after the treatment for 28 days.The prediction model for poor prognosis was established by logistics regression analysis,the fitting degree of model was evaluated by Hosmer-Lemeshow test,and the predictive efficiency of the model was assessed by means of receiver operating characteristic(ROC)curves.RESULTS The proportion of patients complicated with acute kidney injury was signifi-cantly higher in the poor prognosis group than in the favorable prognosis group(P<0.05).The white blood cell counts,urea nitrogen,serum creatinine,total bilirubin,aspartate aminotransferase,alanine aminotransferase,C-reactive protein,procalcitonin,acute physiology and chronic health evaluationⅡ(APACHE Ⅱ)score and sepsis-related organ failure assess-ment(SOFA)score were significantly elevated(P<0.05);the eradication rates of prealbumin and 24-hour lactic acid were reduced(P<0.05).The result of logistic regression analysis showed that complication with acute kidney injury,A-PACHEⅡ score and SOFA score were the independent risk factors for the poor prognosis of the patients with severe pul-monary infection-related sepsis(P<0.05),and the eradication rate of 24-hour lactic acid was the independent protective factor(P<0.05).The prediction model for poor prognosis of the patients with severe pulmonary infection-related sepsis was acquired by multivariate logistic regression equation,and the Hosmer-Lemeshow test showed that the fitting degree of the model was good(x2=12.691,P=0.124).ROC curve analysis indicated that the model showed high predictive effi-ciency,with the area under curve(AUC)0.881,95%CI:0.814-0.949.CONCLUSION The prediction model for poor prognosis of the patients with severe pulmonary infection-related sepsis that is established based on logistics re-gression analysis shows high prediction efficiency,the fitting degree of the model is satisfying,and it can provide data for guidance of diagnosis and treatment of sepsis.
