What this trial studies

This study investigates whether the daily administration of 0.5L of alcohol-containing wheat beer can reduce the prevalence of delirium in intensive care unit (ICU) patients compared to water. The intervention is administered at 8 pm for six consecutive days to patients at risk of developing delirium, particularly those with an expected ICU stay of 24 hours or more. Delirium is a common and serious complication in ICU settings, and this study aims to explore a novel, non-pharmacological approach to its prevention.

Who should consider this trial

Good fit: Ideal candidates include ICU patients aged 18 years and older, weighing at least 50 kg, who are expected to stay in the ICU for 24 hours or more and have a naso-gastric tube in place.

Not a fit: Patients with pre-existing liver conditions, active psychosis, or a history of alcohol abuse are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of delirium in ICU patients, leading to improved patient outcomes and reduced healthcare costs.

How similar studies have performed: While there are various pharmacological approaches to prevent delirium, this study's non-pharmacological method using wheat beer is novel and has not been extensively tested in similar contexts.
