Gastrointestinal Flexible Endoscopes: Infection Control Risks, Lessons Learned from Outbreaks, and Centers for Disease Control and Prevention Guidance

Flexible endoscopes require cleaning, high-level disinfection, and sterilization between each patient use to reduce risk of transmitting pathogens. Public health investigations have identified concerns, including endoscope damage, mishandling, and reprocessing deficiencies, placing patients at risk for transmission of bacterial, viral, and other pathogens. Findings from outbreak investigations and other studies have led to innovations in endoscope design, use, and reprocessing, yet infection risks related to contaminated or damaged endoscopes remain. Strict adherence to infection control guidelines and manufacturer instructions for use, utilization of supplemental guidance, and training and oversight of reprocessing personnel, reduce risk of pathogen transmission by flexible endoscopes.
