certified flex endoscope reprocessor Interview Questions and Answers

1. What is a flexible endoscope?

   • Answer: A flexible endoscope is a long, thin, flexible tube with a camera and light source at the end, used to visualize the interior of the body through a natural orifice.

2. Describe the process of high-level disinfection of a flexible endoscope.

   • Answer: High-level disinfection involves pre-cleaning, leak testing, manual cleaning, rinsing, and immersion in a high-level disinfectant according to the manufacturer's instructions and regulatory guidelines. This typically involves using a liquid chemical sterilant such as glutaraldehyde or peracetic acid. Post-disinfection rinsing is crucial.

3. What are the key differences between high-level disinfection and sterilization?

   • Answer: Sterilization eliminates all microbial life, including spores, while high-level disinfection kills or inactivates a wide range of microorganisms but may not eliminate all spores. Sterilization is generally achieved through methods such as steam sterilization (autoclaving) or ethylene oxide gas sterilization, neither of which are typically used for flexible endoscopes due to the risk of damage.

4. Explain the importance of pre-cleaning endoscopes.

   • Answer: Pre-cleaning is crucial because it removes gross soil and organic matter, preventing the formation of biofilms that can interfere with subsequent disinfection and increase the risk of infection. It protects the endoscope from damage during the cleaning process.

5. What are the potential consequences of inadequate endoscope reprocessing?

   • Answer: Inadequate reprocessing can lead to patient infections (e.g., CRE, C. difficile), outbreaks, legal action, and reputational damage for the healthcare facility.

6. List three types of high-level disinfectants used for endoscopes.

   • Answer: Glutaraldehyde, Peracetic acid, Ortho-phthalaldehyde (OPA)

7. What are the safety precautions you should take when handling high-level disinfectants?

   • Answer: Wear appropriate personal protective equipment (PPE) including gloves, eye protection, and a gown. Work in a well-ventilated area. Follow manufacturer's instructions carefully. Avoid skin contact. Dispose of waste properly.

8. How do you ensure the effectiveness of the high-level disinfectant?

   • Answer: Use an automated endoscope reprocessor (AER) which monitors parameters like temperature and disinfectant concentration, use endoscope quality control tests like leak testing and visual inspection, and regularly perform biological indicator testing to validate the effectiveness of the disinfectant.

9. What is a biological indicator and how is it used in endoscope reprocessing?

   • Answer: A biological indicator (BI) contains a known number of resistant bacterial spores (e.g., Geobacillus stearothermophilus for steam sterilization, Bacillus atrophaeus for liquid chemical sterilants). After the disinfection/sterilization cycle, the BI is incubated. No growth indicates successful inactivation of the spores, confirming the efficacy of the process. For high-level disinfection, a BI may be used to verify the efficacy of the high-level disinfectant used in the AER.

10. Describe the process of leak testing an endoscope.

    • Answer: Leak testing involves submerging the endoscope in water and applying air or water pressure to check for leaks in the channels. Any bubbles indicate a leak, requiring repair or disposal of the endoscope.

14. What are the different channels in a flexible endoscope and their functions?

    • Answer: Typically includes a water/air channel for insufflation, a suction channel for removing fluids, and a biopsy channel for collecting tissue samples. Some endoscopes have additional channels for instrument insertion.

15. How often should an AER be validated?

    • Answer: AER validation should be performed according to manufacturer's instructions, but usually involves regular monitoring, testing, and documentation, often including periodic biological indicator testing.

16. What are the safety concerns associated with glutaraldehyde?

    • Answer: Glutaraldehyde is a potent irritant and can cause skin sensitization, respiratory irritation, and eye damage. It's also a potential carcinogen.

17. What are some common endoscope malfunctions and how are they addressed?

    • Answer: Examples include leaks, broken valves, and malfunctioning light sources. These require repair by trained personnel or may necessitate endoscope replacement.
