Endoscopy Basics
Name one complex feature of flexible endoscopes that makes them challenging to reprocess.
Long, narrow lumens and multiple channels.
What type of pathogens can be transmitted through inadequately reprocessed endoscopes?
Exogenous pathogens, such as antibiotic-resistant bacteria.
What is the first step in reprocessing a flexible endoscope?
Precleaning or point-of-use cleaning.
Why is ongoing education and competency validation important for personnel reprocessing endoscopes?
To ensure adherence to infection prevention protocols and proper reprocessing techniques.
What is a duodenoscope and why is it difficult to clean?
A duodenoscope is used during ERCP procedures and has an elevator channel, making it harder to clean and disinfect.
Name one type of infection linked to endoscopes despite strict adherence to reprocessing protocols.
Carbapenem-resistant Enterobacteriaceae (CRE) infections.
Why is leak testing performed on endoscopes?
To detect damage that could lead to fluid invasion and potential infection transmission.
What should be included in a facility's quality assurance documentation for endoscope reprocessing?
Logs indicating the patient's details, procedure, endoscope serial number, and staff involved in each stage.
What classification do flexible endoscopes fall under according to the Spaulding system?
Semicritical devices.
What is biofilm and why is it significant in the context of endoscopy?
A matrix of microorganisms that is difficult to remove and can decrease the effectiveness of disinfection and sterilization processes.
What type of water should be used for the final rinse in manual reprocessing?
Critical water or sterile water, depending on the manufacturer's IFU.
What is one recommendation for the storage of reprocessed endoscopes?
Store them in a clean, well-ventilated, and secured area, preferably in drying cabinets.
