What is the typical recommended maximum reuse period (in days) for a single-use enzymatic detergent solution?
Answer: Single-use only; must be discarded after each scope cleaning
Enzymatic detergent solutions are single-use and must be discarded after each endoscope cleaning cycle to prevent cross-contamination and enzyme depletion.
Which type of brush is required when mechanically cleaning the channels of a flexible endoscope?
Answer: A channel-specific brush that fits the channel diameter snugly
Brushes must be sized to fit the channel diameter snugly to ensure full contact with channel walls, and must be long enough to pass completely through the channel.
In an automated endoscope reprocessor (AER), what is the function of the self-disinfection cycle?
Answer: To decontaminate the machine's internal fluid pathways between uses
The AER self-disinfection cycle runs HLD or another disinfectant through the machine's own internal tubing and channels to prevent the machine itself from becoming a source of contamination.
What personal protective equipment (PPE) is required as a minimum when manually cleaning contaminated endoscopes?
Answer: Gloves, fluid-resistant gown, face shield or mask and eye protection
OSHA and SGNA guidelines require gloves, a fluid-resistant gown, and face/eye protection to protect reprocessing staff from splashes of blood, body fluids, and chemical disinfectants.
What is the significance of the 'reuse life' stated on a high-level disinfectant product label?
Answer: The maximum number of days the activated solution can be used before it must be discarded regardless of MEC
The reuse life is the manufacturer-validated maximum number of days an activated HLD solution may be used; it must be discarded after this period even if MEC testing still shows adequate concentration.
Which component of a flexible endoscope is most frequently identified as a source of reprocessing failures and subsequent patient infections?
Answer: The elevator mechanism of duodenoscopes
The elevator mechanism (forceps elevator) of duodenoscopes has a complex, difficult-to-clean design that has been linked to multiple outbreaks of carbapenem-resistant organism transmission.
How should reprocessing staff document completion of each step in the endoscope reprocessing cycle?
Answer: Record each step in a traceability log tied to the scope and patient
Traceability documentation linking the scope identifier, patient, reprocessing steps, chemical lot numbers, and staff initials is essential for quality assurance and outbreak investigation.
