What this trial studies

This clinical trial aims to evaluate the effectiveness of prophylactic gentamicin bladder irrigation in preventing catheter-associated urinary tract infections (CAUTIs) in hospitalized patients. It is a prospective randomized controlled trial that will involve patients over 18 years old who have an indwelling Foley catheter due to trauma, surgical, or neuro-critical care conditions. The study seeks to address the high incidence of CAUTIs, which are considered preventable but still occur frequently despite existing prevention strategies. By testing this intervention, the trial hopes to provide a new approach to reducing CAUTI rates in critical care settings.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who are admitted with trauma, surgical, or neuro-critical care diagnoses and have an indwelling Foley catheter.

Not a fit: Patients with recent urinary infections, traumatic bladder injuries, or allergies to gentamicin will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of CAUTIs, leading to better patient outcomes and lower healthcare costs.

How similar studies have performed: While there have been various approaches to preventing CAUTIs, the specific use of gentamicin bladder irrigation in this context is novel and has not been extensively tested.
