Automated endoscope washer disinfectors offer effective decontamination for flexible endoscopes, reducing staff exposure to disinfectants. Proper machine selection and water quality are crucial for safe and thorough instrument processing.

Area of Science:

  • Medical device reprocessing
  • Infection control
  • Endoscopy

Background:

  • Flexible endoscopes require rigorous decontamination to prevent patient-to-patient transmission of infections.
  • Manual cleaning methods pose risks of incomplete disinfection and staff exposure to hazardous chemicals.
  • Automated endoscope washer disinfectors (AEWDs) are increasingly adopted for improved safety and efficacy.

Purpose of the Study:

  • To outline the essential features and considerations for selecting appropriate automated endoscope washer disinfectors.
  • To emphasize the importance of effective cleaning, disinfection, rinsing, and safety measures in AEWDs.
  • To guide purchasers in evaluating AEWD performance and verifying manufacturer claims.

Main Methods:

  • Review of AEWD functionalities including cleaning, disinfection, and rinsing of all endoscope components.

  • Assessment of safety features such as fume containment for disinfectants like glutaraldehyde.
  • Consideration of water quality requirements, particularly sterile or filtered water for invasive procedures.
  • Evaluation of factors influencing machine choice: mobility, disinfectant type, throughput, and capacity.

    • Main Results:

    • AEWDs are more effective than manual methods and minimize operator contact with disinfectants.
    • Proper functioning requires effective cleaning, disinfection, and rinsing of all channels and surfaces without instrument damage.
    • Safety measures like fume containment and self-disinfect facilities are essential.
    • Microbiological quality of rinse water is critical; sterile or filtered water is necessary for bronchoscopes and invasive endoscopes.

    Conclusions:

    • Selection of AEWDs should consider specific needs like mobility, disinfectant used, and workflow.
    • Verification of manufacturer claims through independent testing is strongly advised for purchasers.
    • Ensuring proper decontamination protocols with AEWDs is vital for patient safety and healthcare worker protection.
