According to the Spaulding classification, endoscopes that contact intact mucous membranes are categorized as which level of device?
Answer: Semi-critical
Semi-critical devices contact intact mucous membranes and require high-level disinfection at minimum.
What is the minimum contact time required for high-level disinfection of endoscopes using 2% glutaraldehyde at 25°C?
Answer: 20 minutes
High-level disinfection with 2% glutaraldehyde requires a minimum of 20 minutes at 25°C.
Which step in endoscope reprocessing is considered the most critical for reducing bioburden?
Answer: Manual cleaning (brushing and enzymatic detergent)
Manual cleaning physically removes organic material and bioburden that can interfere with disinfection efficacy.
A patient scheduled for endoscopy has a known history of Creutzfeldt-Jakob disease (CJD). What is the recommended approach?
Answer: Use a disposable endoscope or quarantine the scope after use
Prions are resistant to standard disinfection. Guidelines recommend disposable endoscopes or quarantining/destroying the scope.
What is the purpose of performing a leak test on an endoscope before reprocessing?
Answer: To detect damage to the endoscope's internal channels and outer sheath
Leak testing detects holes or cracks that could allow fluid infiltration and damage internal components or harbor microorganisms.
Which organism is the most frequently reported pathogen associated with endoscope-related infections due to inadequate reprocessing?
Answer: Pseudomonas aeruginosa
Pseudomonas aeruginosa is most commonly reported due to its ability to thrive in moist environments and form resilient biofilms.
