Analysis on the risk factors and construction of a nomogram model for postoperative pulmonary infection after tibial plateau fractures surgery
Objective To explore the risk factors and construct a nomogram model for postoperative pulmonary infection in patients with tibial plateau fractures.Methods The clinical data of 322 patients with tibial plateau fractures who underwent surgery in Nanjing Gaochun People's Hospital and Nanjing Gaochun Hospital of Traditional Chinese Medicine from April 2021 to July 2023 were retrospectively analyzed.According to the diagnostic criteria of pulmonary infection,28 patients developed pulmonary infection(infection group),and 294 patients did not(non-infection group).Univariate analysis was used to screen the factors related to pulmonary infection after tibial plateau fractures surgery,and multivariate logistic regression analysis was used to analyze the risk factors affecting pulmonary infection after tibial plateau fractures surgery.A nomogram model was constructed for the independent risk factors,and the predictive efficacy of the model was tested using ROC curves and calibration curves.Results There were statistically significant differences in age,proportion of advanced age,fracture type,history of smoking,history of alcohol consumption,fracture-to-admission time,proportion of cardiovascular diseases,proportion of respiratory diseases,proportion of neurological diseases,and WBC between the two groups(all P＜0.05).Multifactorial logistic regression analysis showed that advanced age,history of smoking,history of alcohol consumption,longer fracture-to-admission time,abnormal WBC,and abnormal hs-CRP were all independent risk factors for pulmonary infections after tibial plateau fractures surgery(all P＜0.05).Independent risk factors such as advanced age,history of smoking,history of alcohol consumption,fracture-to-admission time,WBC,hs-CRP were combined to construct a nomogram model of pulmonary infection after tibial plateau fractures surgery,and the ROC curve was used to validate the model,which was found to have an AUC of 0.947,indicating that the model had a good predictive efficacy.Calibration curves were showed that the prediction curves of this model had a good fit with the clinical actual results.Conclusion Advanced age,history of smoking,history of alcohol consumption,longer fracture-to-admission time,abnormal WBC,and abnormal hs-CRP are risk factors for pulmonary infection after tibial plateau fractures surgery.The nomogram constructed based on these factors can well identify high-risk patients.
