Assessing infection risks in digestive endoscopy environments

Risk Assessment of Indirect Exposure to the Environment in the Gastrointestinal Endoscopy Center

NA · Peking Union Medical College Hospital · NCT05321043

This study is testing how germs might spread in a digestive endoscopy center by looking at where patients touch and how it could lead to infections.

What this trial studies

This study aims to evaluate the risk of indirect exposure and transmission of infections in a digestive endoscopy center by simulating contact with environmental surfaces using a Vitamin B2 solution. The research involves analyzing key exposure areas within the endoscopy room and marking patients' hands with a fluorescent marker before their procedures. The study records the endoscopy process and assesses the residual fluorescence on surfaces after the procedures to understand touch behaviors and potential contamination. This case-only design focuses on identifying high-risk areas to improve infection control protocols.

Who should consider this trial

Good fit: Ideal candidates include patients scheduled for gastroscopy at the digestive endoscopy center, regardless of age or gender.

Not a fit: Patients who are allergic to Vitamin B2 or have severe health conditions that contraindicate endoscopy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance infection control measures in endoscopy centers, leading to safer procedures for patients and healthcare staff.

How similar studies have performed: While studies on infection control in medical settings exist, this specific approach using Vitamin B2 for indirect exposure assessment is relatively novel.
