What this trial studies

This study investigates whether using two sterile towels for drying hands after surgical handwashing reduces contamination events compared to using just one towel. It is a randomized, multicenter trial involving 72 healthcare workers and surgical residents across three hospitals in Bogotá, Colombia. Participants will have fluorescent cream applied to simulate bacteria, and contamination will be assessed post-drying. The study aims to provide insights into optimal hand hygiene practices to prevent surgical wound infections.

Who should consider this trial

Good fit: Ideal candidates include healthcare workers and surgical residents who perform surgical handwashing at least once a week.

Not a fit: Patients who do not perform surgical handwashing or those with specific exclusions such as allergies to the fluorescent cream will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved hand hygiene practices, reducing the risk of surgical wound infections and healthcare-associated infections.

How similar studies have performed: Previous studies have shown varying results regarding hand hygiene practices, but this specific comparison of towel usage is novel.
