Why the study?
Can a preoperative prediction rule identify cardiac surgery patients at high risk for postoperative delirium?
Can a preoperative prediction rule identify cardiac surgery patients at high risk for postoperative delirium?
A 4-item preoperative prediction rule can identify cardiac surgery patients at high risk for postoperative delirium, enabling targeted monitoring and prevention.
May support preoperative delirium risk stratification in cardiac surgery; leaves open need for validation and intervention trials.
Delirium occurs frequently after cardiac surgery. Using 4 preoperative characteristics, clinicians can determine cardiac surgery patients' risk for delirium. Patients at higher delirium risk could be candidates for close postoperative monitoring and interventions to prevent delirium.
