Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 55 years or older who are currently experiencing hypoactive delirium.

Probably not a fit

Patients who have a history of delirium prior to ICU admission or those with conditions such as dementia or active psychosis may not benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness of melatonin in treating hypoactive delirium in adult patients aged 55 and older who are currently experiencing this condition. The study utilizes a randomized, controlled design, comparing melatonin to a placebo to assess improvements in delirium symptoms. The trial aims to address the lack of pharmacological treatment options for hypoactive delirium, which is often overlooked despite its prevalence and serious consequences. Participants will be evaluated using specialized assessment methods to confirm their eligibility based on specific delirium criteria.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for hypoactive delirium, potentially improving patient outcomes and quality of life.

How similar studies have gone: While many studies have focused on hyperactive and mixed delirium, this approach to treating hypoactive delirium with melatonin is relatively novel and has not been extensively tested.
