Perioperative care and outcomes for older adults having surgery
Official title: Elderly Patients Undergoing Surgery During Perioperative Period: a Prospective Cohort Study
Run by Second Affiliated Hospital of Wenzhou Medical University · NCT07314762 · Data updated 2026-11-12
This project will follow people aged 65 and older who are having surgery to try to identify clinical and biological factors that raise the risk of postoperative delirium and other complications.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are people aged 65 or older treated at the participating hospitals who agree to provide informed consent and perioperative clinical information and biological samples.
✕Probably not a fit
People younger than 65 or those who refuse consent or sampling will not be eligible and therefore will not receive direct benefit from participation.

What this trial studies
This is a prospective cohort study enrolling patients aged 65 or older at a single medical center and collecting clinical data and biological samples across the perioperative period. Samples and standardized clinical information will be obtained before, during, and after surgery to capture changes linked to complications. Investigators will monitor patients for postoperative delirium, other complications, length of stay, and short-term outcomes. The collected data will be used to explore possible mechanisms and to build a risk prediction model for postoperative complications in older surgical patients.
Why it matters
Potential benefit: If successful, the work could help clinicians identify high-risk older patients earlier and target preventive measures to reduce delirium and other postoperative complications.
How similar studies have gone: Previous cohort studies have identified some risk factors and produced predictive models for postoperative delirium, so this work builds on an existing but still-improving evidence base.
