The effect of preoperative cognitive impairment and type of vascular surgery procedure on postoperative delirium with associated cost implications

摘要

Objective: Postoperative delirium (POD) has a high prevalence among vascular surgery patients, increasing morbidity, mortality, and length of stay. We prospectively studied preoperative risk factors for delirium that can be assessed by the surgical team to identify high-risk patients and assessed its impact on hospital costs.
