All data were randomly stratified into a training set and a testing set at a ratio of 8:2. Data were analyzed via multiple logistic regression analysis with receiver operating characteristic (ROC) curves and areas under the curve. This model was further validated by estimating calibration and discrimination. A nomogram was ultimately developed.Results: A total of 736 eligible patients were enrolled, 27.20% of whom developed CPSP within 6 months postoperatively. Preoperative pain in the surgical area (OR=2.456, 95% CI:1.814– 3.327, P< 0.001), preoperative depression state (OR=1.256, 95% CI:1.146– 1.378, P< 0.001), surgical type (OR=7.138, 95% CI:3.548– 14.364, P< 0.001), acute postoperative numerical rating scale score (OR=5.537, 95% CI:3.607– 8.499, P< 0.001) and analgesic type (patient-controlled epidural analgesia: OR=0.129, 95% CI:0.055– 0.299, P< 0.001; patient-controlled intravenous analgesia: OR=0.033, 95% CI:0.011– 0.097, P< 0.001) were identified as independent significant factors associated with CPSP. A prognostic model was established and further validated. An ROC curve confirmed the predictive ability of this model with a high sensitivity value of 92.12% (95% CI:86.90– 95.74) and specificity value of 91.72% (95% CI:88.77– 94.11). A nomogram was developed to simplify the use of the predictive model in clinical practice.Conclusion: This prognostic model could be of great value in clinical practice, serving as the basis for early personalized analgesic management of elderly patients undergoing hip arthroplasty.Keywords: chronic postsurgical pain, CPSP, prognostic model, nomogram, retrospective study |
