Delirium and Light: Exploring Modifiable Risk Factors in Critically Ill Adults

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

This pilot observational study, conducted at a major hospital network, follows adults over 50 who have recently been admitted to critical care to see if light exposure and sleep patterns relate to delirium risk. It will collect blood samples and monitor daytime light exposure to explore possible connections with delirium and cognitive outcomes. The goal is to identify modifiable factors that could help reduce delirium and inform future interventions in the ICU setting.
