Aim To develop and validate a risk prediction model for estimating the likelihood of insomnia in patients with acute exacerbations chronic obstructive pulmonary disease (AECOPD). Methods This prospective study enrolled 253 AECOPD treated at Department Respiratory Critical Care Medicine, Chaohu Hospital Affiliated Anhui Medical University, between September 2022 April 2024. Patients were randomly assigned to training set testing 7:3 ratio. Least Absolute Shrinkage Selection Operator (LASSO) regression analysis was conducted identify factors associated AECOPD. A nomogram constructed based on four identified variables visualize model. Model validation involved Hosmer-Lemeshow test, its performance assessed through receiver operating characteristic (ROC) curves, calibration decision curve (DCA). interpretability further enhanced using SHapley Additive exPlanations (SHAP). Results PSQI grade, marital status (widowed), white blood cell (WBC) count, eosinophil percentage (EOS%) as significant predictors The these exhibited excellent predictive performance, areas under ROC (AUCs) 0.987 0.933 sets, respectively. curves test demonstrated strong agreement predicted observed outcomes, while DCA confirmed model’s superior clinical utility. Conclusion established estimate probability accuracy applicability, offering valuable guidance early identification management this population.
