Effectiveness of flexible gastrointestinal endoscope reprocessing

Area of Science:

• Infection Control
• Medical Device Reprocessing
• Gastroenterology

Background:

• Endoscopes require meticulous reprocessing to prevent patient-to-patient transmission of infections.
• Inadequate reprocessing practices pose a significant risk in healthcare settings.

Purpose of the Study:

• To evaluate the effectiveness of endoscope reprocessing practices across multiple healthcare services.
• To identify the prevalence of endoscope contamination and associated pathogens.

Main Methods:

• A cross-sectional evaluation of endoscope reprocessing in 37 healthcare services.
• Microbiological sampling and analysis of reprocessed endoscopes, including colonoscopes and gastroscopes.
• Assessment of adherence to recommended reprocessing guidelines.

Main Results:

• Contamination was identified in 91.6% of the evaluated services.
• Bacteria, fungi, and/or mycobacteria were isolated from 84.6% of colonoscopes and 80.6% of gastroscopes.
• Significant microbial loads (CFUs/mL) were detected, indicating potential infectious risk.

Conclusions:

• Current endoscope reprocessing practices are frequently inadequate, failing to eliminate microbial contamination.
• Non-adherence to guidelines contributes to the high rates of contaminated endoscopes.
• Patients undergoing gastrointestinal endoscopy are exposed to a diverse range of pathogens due to ineffective reprocessing.
