New developments in processing semicritical items: Channeled endoscopes, probes, optical and nasal devices, and...

Area of Science:

• Infection Control and Prevention
• Medical Device Reprocessing
• Healthcare Epidemiology

Background:

• Semicritical medical devices contact mucous membranes or nonintact skin, necessitating high-level disinfection or sterilization.
• Examples include gastrointestinal (GI) endoscopes and endocavitary probes, requiring rigorous reprocessing.
• Inadequate disinfection poses significant infection risks to patients.

Purpose of the Study:

• To review current recommendations and advancements in disinfection and sterilization of semicritical medical devices.
• To highlight infection risks associated with reusable medical instruments.
• To emphasize the importance of adherence to reprocessing guidelines.

Main Methods:

• Literature review of published studies on disinfection and sterilization of semicritical items.
• Identification of key recommendations and technological advancements.
• Analysis of infection outbreaks linked to medical devices.

Main Results:

• Reusable endoscopes are frequently implicated in healthcare-associated infection outbreaks.
• Infection risk varies by procedure type (e.g., colonoscopy) and patient factors.
• Gastrointestinal and bronchoscopes have been associated with numerous outbreaks.

Conclusions:

• Strict adherence to current disinfection and sterilization recommendations is essential.
• Following manufacturer's instructions for use (IFU) is critical for preventing outbreaks.
• Consistent implementation of reprocessing protocols safeguards patient safety.
