Disposable flexible endoscopes offer infection control but face economic barriers. A two-step disinfection process using peracetic acid effectively reduces microorganisms and mitigates prion risk.

Area of Science:

  • Medical Devices
  • Infectious Disease Control
  • Materials Science

Context:

  • Flexible endoscopes are crucial for diagnostics but pose infection risks.
  • Autoclave sterilization is unsuitable for heat-sensitive endoscope materials.
  • Economic factors currently limit the widespread adoption of disposable endoscopes.

Purpose:

  • To outline a disinfection protocol for flexible endoscopes that ensures safety against infection transmission.
  • To address the limitations of heat-sensitive materials in sterilization methods.
  • To propose a method for managing prion risk associated with endoscope reprocessing.

Summary:

  • A two-step disinfection process is recommended for flexible endoscopes: mechanical cleaning with detergent followed by immersion in a peracetic acid bath for 30 minutes.

  • This high-level disinfection achieves bactericidal, virucidal, fungicidal, and sporicidal activity.
  • Peracetic acid and a double cleaning method are proposed to manage prion risk by eliminating protein debris and replacing glutaraldehyde.

    • Impact:

    • The proposed disinfection protocol enhances patient safety by minimizing infection transmission risks.
    • This approach offers a viable alternative to costly disposable endoscopes, improving cost-effectiveness in healthcare.
    • Effective reprocessing strategies are crucial for maintaining the usability of reusable medical instruments and preventing healthcare-associated infections.
