Abstract:
In the four decades since the introduction of flexible endoscopy into medical practice, nearly 300 cases of human infections or pseudoinfections involving bacteria, fungi, parasites, and viruses have been linked to endoscopic procedures. In the majority of such cases, inadequate cleaning and disinfection techniques during the reprocessing of the instruments or their accessories have been likely contributing factors. Working groups from major gastroenterology societies and infection control organizations have established standards of care for the routine maintenance of endoscopic equipment in order to decrease the rates of infection even further. Since the institution of these standards, rates of transmission of infections to patients have decreased, though have not been completely resolved. This article reviews the available literature on transmission of pathogenic agents through endoscopic procedures, summarizes the current guidelines for the care of endoscopic equipment, and discusses available preventive measures aimed at decreasing the risk of endoscopy-related infections.
Insights
Flexible endoscopy reprocessing requires strict adherence to cleaning and disinfection standards to prevent patient infections. While guidelines have reduced transmission, ongoing vigilance is crucial for patient safety in endoscopic procedures.
Area of Science:
- Infectious Diseases
- Gastroenterology
- Medical Device Reprocessing
Background:
- Flexible endoscopy has been linked to nearly 300 human infections since its introduction.
- Inadequate reprocessing of endoscopic instruments is a primary cause of these infections.
- Despite established standards, endoscopy-related infections persist.
Purpose of the Study:
- To review literature on pathogenic agent transmission via endoscopic procedures.
- To summarize current guidelines for endoscopic equipment care.
- To discuss preventive measures against endoscopy-related infections.
Main Methods:
- Literature review of transmission of pathogenic agents.
- Summary of current infection control guidelines for endoscopic equipment.
- Discussion of preventive strategies.
Main Results:
- Inadequate reprocessing is the main factor in endoscopy-related infections.
- Established standards have decreased but not eliminated infection transmission.
- Further preventive measures are needed.
Conclusions:
- Adherence to reprocessing standards is critical for reducing endoscopy-related infections.
- Ongoing efforts and updated guidelines are necessary to enhance patient safety.
- Minimizing infection risk requires continuous improvement in equipment care protocols.
