Summary
This study tests whether giving caffeine to adults aged 70 and older after major surgery can lower their risk of postoperative delirium—a state of sudden confusion. Researchers will compare low-dose and high-dose caffeine against a placebo in 250 participants. The goal is to see if a common, safe substance can improve mental recovery.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
caffeine citrate
What this could lead to
If it works, this could point toward a simple, low-cost way to prevent confusion and cognitive decline after major surgery in older adults.
What could go wrong
This is a mid-stage trial with only 250 participants, so results may not apply to everyone. Caffeine can cause side effects like jitters or heart issues, and it might not reduce delirium at all.
