Sex differences in postoperative delirium and whether family visits help

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Postoperative delirium is common in older adults after non-cardiac surgery and is linked to worse outcomes and higher costs. This observational study will examine whether men and women have different risks for delirium after surgery and whether the amount of family visitation mediates that risk. Researchers will collect data on delirium occurrence, sex, and family visit patterns to explore potential links. The goal is to better understand non-drug approaches that might reduce delirium risk in older adults.
