Disinfection, sterilization, and antisepsis: An overview

Area of Science:

• Infection Prevention and Control
• Medical Device Reprocessing
• Sterilization and Disinfection

Background:

• Invasive procedures necessitate medical devices or surgical instruments contacting sterile tissue or mucous membranes.
• The required level of reprocessing (sterilization, high-level disinfection, low-level disinfection) is determined by the device's intended use and contact level.
• Cleaning is a mandatory prerequisite for high-level disinfection and sterilization processes.

Purpose of the Study:

• To outline the principles of medical device reprocessing based on contact type.
• To emphasize the importance of cleaning, disinfection, and sterilization in infection prevention.
• To highlight the role of antiseptics in healthcare settings.

Main Methods:

• Classification of medical devices into critical, semicritical, and noncritical categories based on tissue contact.
• Description of reprocessing requirements (sterilization, high-level disinfection, low-level disinfection) for each category.
• Explanation of the necessity of cleaning prior to disinfection or sterilization.

Main Results:

• Critical items require sterilization, semicritical items require high-level disinfection, and noncritical items require low-level disinfection.
• Antiseptics play a vital role in infection prevention strategies.
• Effective hand hygiene, surgical antisepsis, and pre-operative skin preparation rely on antiseptics.

Conclusions:

• Appropriate reprocessing of medical devices is essential for preventing healthcare-associated infections.
• Adherence to established protocols for cleaning, disinfection, and sterilization ensures patient safety.
• The judicious use of antiseptics is fundamental to comprehensive infection control programs.
