Items to be disinfected or sterilized at the point of use must be?

The requirement for items to be disinfected or sterilized at the point of use is centered around the necessity of proper cleaning according to the manufacturer's Instructions for Use. This is because the effectiveness of disinfection or sterilization processes relies heavily on the removal of organic material, soil, or contaminants from the surface of the items being treated. If items are not properly cleaned, the disinfection or sterilization process may not be effective, potentially leading to the survival of pathogens and increasing the risk of infection.

While semi-critical and non-critical devices are relevant in the context of infection control, the specific focus on the requirement for proper cleaning emphasizes adherence to the manufacturer's guidelines. These guidelines typically outline the appropriate methods and materials necessary for cleaning, which is a critical step prior to any disinfection or sterilization efforts. Therefore, ensuring that items are cleaned according to these instructions is fundamentally important in achieving the desired level of safety and efficacy in patient care and infection prevention practices.
