Integrating Clinical Information and Electrocardiographic Signal Features to Develop a Prediction Model for Postoperative Delirium in Older Patients: A Prospective Observational Study
Purpose Postoperative delirium (POD) is a frequent and serious complication in older surgical patients. While conventional prediction models rely heavily on subjective clinical indicators, this study aimed to develop a simple, non-invasive preoperative risk prediction model by integrating objective physiological signal...
