Evaluation of Postoperative Delirium in Cardiac Surgery Patients With the SDACS Screening Tool: A Multicenter-Multiphase Study
This study developed and validated the SDACS screening tool to predict postoperative delirium in cardiac surgery patients. Conducted across three academic hospitals with 920 participants, it identified four key predictors: chronic opioid use, hearing impairment, benzodiazepine history, and poor postoperative sleep. The tool demonstrated strong predictive power (AUC = 0.897), offering clinicians a practical instrument to guide early interventions.
