Do women face higher delirium risk after surgery? new study investigates
NCT ID NCT07502391
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether older women are more likely than men to develop confusion after surgery (postoperative delirium) and whether family visits play a role. Researchers will follow 471 patients aged 65 and older having non-cardiac surgery. No new treatments are tested—just careful observation to understand these links.
