Abstract: OBJECTIVE: To construct and validate a nomogram for prediction of in-hospital postoperative heart failure (PHF) in elderly patients with hip fracture. METHODS: This was a retrospective cohort study. The patients aged ≥65 years undergoing hip fracture surgery in Peking University Third Hospital from July 2015 to December 2023 were enrolled. The patients admitted from July 2015 to December 2021 were divided into a development cohort, and the others admitted from January 2022 to December 2023 in to a validation cohort. The patients ' clinical data were collected from the electronic medical record system. Univariate and multivariate Logistic regression were employed to screen the predictors for PHF in the patients. The R software was used to construct a nomogram. Internal and external validation were performed by the Bootstrap method. The discriminatory ability of the model was determined by the area under the receiver operating characteristic curve (AUC). The calibration was evaluated by the calibration plot and Hosmer-Lemeshow goodness-of-fit test. Decision curve analysis (DCA) was performed to assess the clinical utility. RESULTS: =0.791) showed its satisfactory calibration. Clinical usefulness of the nomogram was confirmed by decision curve analysis. CONCLUSION: An easy-to-use nomogram for prediction of in-hospital PHF in elderly patients with hip fracture is well developed. This preoperative risk assessment tool can effectively identify patients at high risk of PHF and may be useful for perioperative management optimization.
