Analysis of risk factors for postoperative incision infection in elderly lung cancer patients
Objective To study the risk factors of postoperative incision infection in elderly lung cancer patients.Methods 102 elderly lung cancer patients undergoing surgery in our hospital from February 2018 to October 2023 were divided into infected group(12 cases)and non-in-fected group(90 cases)according to whether incisional infection occurred after surgery.Univariate analysis and multivariate logistic regression were used to analyze the risk factors of postoperative incision infection in elderly lung cancer patients,and a logistic regression model was constructed,and the ROC curve was used to analyze the predictive value of postoperative incision infection in elderly lung cancer patients.Results The univariate analysis showed that the operation time,resection range and albumin level(P＜0.05).Multivariate logistic regression analysis showed that operation time 3 h,total lung resection,and 3 d postoperative albumin level were independent risk factors for the development of postoperative cancer infection(P＜0.05).AUC of elderly lung cancer patients was 0.814(95％CI:0.700-0.928,P＜0.05),prediction sensitivity was 78.68％and specificity was 71.11％.Conclusion Operation time of 3 h,total lung resection and 3d postoperative albumin level are independent risk factors for the occurrence of postoperative incision infection in elderly lung cancer patients,and the logistic regression model constructed based on this has certain predictive value for postoperative incision infection in elderly lung cancer patients.
