The field of infection prevention describes a hierarchy of removal of microorganisms from surfaces including medical equipment and instruments. Cleaning is the lowest level, accomplishing substantial removal. Disinfection involves the removal of all pathogens other than bacterial spores.
He also classified levels of germicidal activity as "high", "intermediate", and "low". While influential, the Spaulding scheme is susceptible to oversimplification and can be difficult to implement.

The operations of a sterile services department usually consist of the cleaning, disinfection, and sterilization of reusable medical equipment. Reusable medical equipment, or RME, can consist of any medical equipment from stainless steel surgical instrumentation, to IV pumps and crash carts. RME is separated into three classes: non-critical ...
A less specific measurement of effectiveness is the United States Environmental Protection Agency (EPA) classification into either high, intermediate or low levels of disinfection. "High-level disinfection kills all organisms, except high levels of bacterial spores" and is done with a chemical germicide marketed as a sterilant by the U.S. Food ...
The practice of reusing medical devices labeled for only one use began in hospitals in the late 1970s. [8] After a thorough review by the U.S. FDA in 1999 and 2000, [8] the agency released a guidance document for reprocessed SUDs that began regulating the sale of these reprocessed devices on the market, [9] under the condition that third-party reprocessors would be treated as the manufacturer ...
Since 1984, the CDC and the NIH have jointly authored the Biosafety in Microbiological and Medical Laboratories (BMBL). The BMBL is an advisory document providing national recommedations for Biosafety Levels, Containment, Decontamination and Disinfection, Transportation, and Disposal of biohazardous agents. [10]
There are two categories of asepsis: medical and surgical. [1] The modern day notion of asepsis is derived from the older antiseptic techniques, a shift initiated by different individuals in the 19th century who introduced practices such as the sterilizing of surgical tools and the wearing of surgical gloves during operations.

[12] [11] In semi-critical situations, or situations with contact of mucous membranes or non-intact skin, high-level disinfectants are required. Cleaning and disinfecting devices with high-level disinfectants, rinsing with sterile water, and drying all equipment surfaces to prevent microorganism growth are methods nurses and doctors must follow.
