Abstract:
Endoscopic examinations and procedures are essential for diagnosis and treatment of gastrointestinal diseases. As a result of poor reprocessing practice microorganisms can be transmitted via endoscope. The majority of infection transmissions is due to insufficient performance of cleaning and disinfection disregarding guidelines of societies of gastrointestinal endoscopy. A review of the literature and a comparison of European and American guidelines for reprocessing flexible endoscopes are given. Differences in the classification of endoscopic devices, on the possibility of prion transmission, recommendations on staff training and protection, quality assurance of reprocessing and evidence-based graduation of guidelines are stressed and discussed. With respect to the procedure of endoscope reprocessing, differences concerning the cleaning solution to choose, necessity of thoroughly manual cleaning and brushing of the accessible endoscope channels (even in the case of subsequent automatic reprocessing endoscopes in washers-disinfectors), disinfection solution, microbiological quality of water for final rinsing and rationale for alcohol flush of endoscope channels for better drying are mentioned. The need for experimental investigations of the cleaning and disinfection process is stressed. In contrast to recent guidelines of European and American societies of gastrointestinal endoscopy, the now updated recommendations of the Robert Koch-Institute for reprocessing flexible endoscopes and endoscopic accessories are evidence-based and graduated.
Insights
Inadequate reprocessing of endoscopes can spread infections. Updated Robert Koch-Institute guidelines offer evidence-based, graduated recommendations for flexible endoscope reprocessing, improving patient safety.
Area of Science:
- Gastroenterology
- Infectious Disease Control
- Medical Device Reprocessing
Background:
- Endoscopic procedures are vital for diagnosing and treating gastrointestinal diseases.
- Inadequate cleaning and disinfection of endoscopes can lead to microorganism transmission and patient infections.
- Current guidelines for endoscope reprocessing vary, particularly between European and American recommendations.
Purpose of the Study:
- To review and compare European and American guidelines for flexible endoscope reprocessing.
- To highlight differences in device classification, prion transmission, staff training, quality assurance, and guideline evidence base.
- To discuss variations in reprocessing procedures, including cleaning solutions, manual cleaning necessity, disinfection, rinsing water quality, and alcohol flushing.
Main Methods:
- Literature review and comparative analysis of European and American guidelines for flexible endoscope reprocessing.
- Examination of specific reprocessing steps, including cleaning, disinfection, rinsing, and drying.
- Evaluation of the Robert Koch-Institute's updated recommendations in contrast to existing guidelines.
Main Results:
- Significant differences exist between European and American guidelines regarding endoscope reprocessing.
- Key areas of divergence include prion transmission, staff training, and the evidence base for recommendations.
- The Robert Koch-Institute's updated recommendations are presented as evidence-based and graduated, addressing identified gaps.
Conclusions:
- There is a critical need for standardized, evidence-based guidelines for flexible endoscope reprocessing to prevent infections.
- Experimental investigations are necessary to further validate and refine cleaning and disinfection processes.
- The updated Robert Koch-Institute recommendations offer a more robust framework for ensuring endoscope reprocessing safety.
