Final answer:
The AAMI's definition of the removal of contamination to a level necessary for further use or intended purpose is associated with cleaning, which aims to reduce the microbial load to safe levels.
Step-by-step explanation:
The Association for the Advancement of Medical Instrumentation's (AAMI) definition of 'The removal of contamination from an item to the extent necessary for further processing or for its intended use' corresponds to cleaning. Cleaning involves sanitization, which is the removal of microbes to achieve levels considered safe for public health. Different levels of microbial control, such as disinfection and sterilization, are used depending on the item's contact with tissues.
For instance, sterilization is necessary for critical items in contact with sterile tissues, and it is the complete removal or killing of all vegetative cells, endospores, and viruses from an item. Cleaning generally achieves decontamination by reducing the microbial load to safe public health levels, and it is distinguished from sterilization or high-level disinfection that are more thorough and may not be necessary for all items.
