  • Title: Disinfection, sterilization and antisepsis: An overview.
    Author: Rutala WA, Boyce JM, Weber DJ.
    Journal: Am J Infect Control; 2023 Nov; 51(11S):A3-A12. PubMed ID: 37890951.
    Abstract:
    BACKGROUND: Each year in the United States there are approximately 100,000,000 outpatient/inpatient surgical procedures. Each of these procedures involves contact by a medical device or surgical instrument with a patient's sterile tissue and/or mucous membrane. A major risk of all such procedures is the introduction of infection. METHODS: We searched published literature for articles on the use and effectiveness of disinfectants, sterilization methods and antiseptics. RESULTS: The level of disinfection is dependent on the intended use of the object: critical (items that contact sterile tissue such as surgical instruments), semicritical (items that contact mucous membrane such as endoscopes), and noncritical (devices that contact only intact skin such as stethoscopes) items require sterilization, high-level disinfection and low-level disinfection, respectively. Cleaning must always precede high-level disinfection and sterilization. Antiseptics are essential to infection prevention as part of a hand hygiene program as well as other uses such as surgical hand antisepsis and pre-operative patient skin preparation. CONCLUSIONS: When properly used, disinfection and sterilization can ensure the safe use of invasive and non-invasive medical devices. Cleaning should always precede high-level disinfection and sterilization. Strict adherence to current disinfection and sterilization guidelines is essential to prevent patient infections and exposures to infectious agents.
