Construction of predictive analysis of postoperative abdominal infection in gastrointestinal malignant tumors by constructing the early warning scale for abdominal infection
Objective To explore the predictive value of constructing an early warning scale for abdominal infection on the occurrence of abdominal infection after surgery for gastrointestinal malignant tumors.Methods 200 patients who underwent surgery for gastrointestinal malignant tumors in the hospital from January 2020 to January 2023 were selected and divided into 23 cases of abdominal infection group and 177 cases of non-abdominal infection group according to whether or not abdominal infection occurred in the postoperative period,and then constructed a risk prediction model for postoperative abdominal infection,adopted the Hosmer-Lemeshow test for the model's fit,and analyzed the risk of postoperative abdominal infection by the work characteristics(ROC)curve of the subjects.The Hosmer-Lemeshow test was used to test the fit of the model,and the value of the risk prediction model was analyzed by using the ROC curve.Results After univariate analysis,age,gender,BMI,NRS2002 score,operation mode,operation time,intraoperative blood loss,postoperative albumin,postoperative hemoglobin,diabetes mellitus,hypertension,cardiac disease,and hospital stay were not the influencing factors of postoperative abdominal infection in gastrointestinal malignant tumors(P＞0.05).Postoperative abdominal pain,postoperative abdominal distension,and postoperative calcitoninogen(PCT)were the influencing factors of postoperative abdominal cavity infection in gastrointestinal malignant tumors(P＜0.05).After multifactorial binary Logistic analysis,postoperative abdominal pain,postoperative abdominal distension,postoperative PCT ≥ 2 μg/L,postoperative maximum body temperature ≥ 37.5 ℃,and postoperative leukocytes≥ 9.95×109/L were the risk factors for postoperative abdominal cavity infection of gastrointestinal malignant tumors(P＜0.05).The Hosmer-Lemeshow goodness-of-fit test showed thatx2=0.949,P=0.996.Hosmer-Lemeshow goodness-of-fit test showed that x2=0.949,P=0.996,and the ROC curve showed that the area under the curve(AUC)of the risk model for postoperative abdominal infection of gastrointestinal malignant tumors was 0.880,and the Jordon's index was 0.760,with the sensitivity and specificity of 78.26％and 97.74％,respectively,and the accuracy for practical application was 95.50％.Conclusion The early warning scale for postoperative abdominal infection of gastrointestinal malignant tumors constructed in this study has a good predictive effect,and can be used as an auxiliary reference for postoperative abdominal infection of gastrointestinal malignant tumors.
