简要总结
The incidence of postoperative hypothermia in patients with laparoscopic gastrointestinal tumors is high. Hypothermia increases the risk of postoperative complications and medical costs. Early warning can effectively reduce the incidence of postoperative hypothermia in patients. Multivariate prediction models help identify high-risk patients and reversible factors. At present, there are few reports on the risk factors and prediction models of postoperative hypothermia in patients with laparoscopic gastrointestinal tumors. Therefore, this study aims to clarify the risk factors of postoperative hypothermia in patients with laparoscopic gastrointestinal tumors. Four machine learning algorithms, traditional Logistic regression analysis, decision tree, random forest and naive Bayes, were used to establish risk prediction models. According to the TRIPOD statement, C-index, Hosmer-Lemeshow ( H-L ) test and decision curve analysis ( DCA ) were used to evaluate the prediction and fitting effects of the models in all aspects, and the optimal model was selected and verified. Provide reference for subsequent research.

结局指标
主要结局
Whether hypothermia occurs
时间窗: Generally 1 ~ 3 hours, up to 3 hours can be observed.
If the patient 's body temperature is lower than 36 °C during this period, it will be determined that the patient has a postoperative hypothermia, and the rewarming measures will be implemented according to the doctor 's advice. If the patient 's body temperature data collected during this period were all greater than or equal to 36 ° C and less than or equal to 37.2 ° C, it was determined that the patient 's body temperature was normal during the postoperative recovery period and no postoperative hypothermia occurred.
