Abstract:Objective: To analyze the risk factors of pain catastrophizing in Trigeminal neuralgia (TN) patients and establish a risk prediction model, so as to provide reference for effectively preventing the occurrence of pain catastrophizing in clinic. Methods: A total of 205 TN patients hospitalized in the pain department of a Grade-A hospital in Jiangxi Province from January 2021 to March 2023 were selected as the research objects. According to whether pain catastrophizing occurred, they were divided into the pain catastrophizing group and the group without pain catastrophizing. Univariate analysis and multivariate Logistic regression were used to explore the risk factors of pain catastrophizing. R software was used to construct the line graph risk prediction model and verify the effect. Results: Logistic regression showed that age, education level, pain degree, anxiety, depression and sleep quality were risk factors for pain disaster in TN patients. Internal verification of Bootstrap method showed that the average area under ROC curve (AUC) was 0.978 and C-Index was 0.978. External verification showed that the AUC was 0.882, the model specificity was 0.941, and the sensitivity was 0.792, indicating good model differentiation. Calibrate curve graph showed good model calibration, and DCA results showed high clinical benefit level of the model. Conclusion: Age, education level, pain degree, anxiety, depression and sleep quality are risk factors for pain catastrophizing in TN patients. The risk prediction model of this column graph has good predictive efficacy and clinical application value.
