Association Between Preoperative Health and Functional Status and Postoperative Complications in Elderly Patients

Using prospectively collected clinical data from the Chinese Perioperative Database of Elderly Patients, this study retrospectively analyzed patients aged ≥65 years who underwent elective non-cardiac, non-neurosurgical procedures under general anesthesia between April 2020 and April 2022. The study examined the associations between various preoperative health and functional status assessment tools and the occurrence of cardiovascular and cerebrovascular complications within 30 days after surgery, aiming to compare the clinical value of different assessment instruments.
