Understanding High-Level Disinfection

What is high-level disinfection and when is it used?

High-level disinfection is the level of decontamination that is second only to sterilization. When is it typically utilized?

Answer:

High-level disinfection is a process that eliminates or kills most pathogenic microorganisms, but not necessarily all forms of microbial life, such as bacterial spores. It is commonly used to decontaminate medical equipment and instruments that come into contact with mucous membranes or non-intact skin, but not sterile tissues.

High-level disinfection plays a crucial role in ensuring the safety of patients and healthcare professionals. By effectively killing or eliminating harmful microorganisms, it helps prevent the spread of infectious diseases in healthcare settings.

Examples of high-level disinfectants include hydrogen peroxide, peracetic acid, and glutaraldehyde. These substances are potent enough to destroy a wide range of pathogens, making them ideal for decontaminating medical equipment.

It's important to select the appropriate level of decontamination based on the intended use of the equipment or surface. Sterilization is reserved for critical items (items that enter sterile tissue or the vascular system). High-level disinfection is used for semi-critical items (items that come into contact with mucous membranes or non-intact skin).
