Disinfection by Healthcare Personnel in Ambulatory Care and Home Care, 12. The exact type of PPE depends on the infectious or chemical agent and the anticipated duration of exposure. Detergent and water are adequate for cleaning surfaces in nonpatient-care areas (e.g., administrative offices). Store sterile items so the packaging is not compromised (e.g., punctured, bent). Prioritize disinfecting frequently touched surfaces. Ensure that packaging materials are compatible with the sterilization process and have received FDA 510[k] clearance. If a cluster of endoscopy-related infections occurs, investigate potential routes of transmission (e.g., person-to-person, common source) and reservoirs. Management of Equipment and Surfaces in Dentistry, 9. prevent common sources of extrinsic contamination of germicides (e.g., container contamination or surface contamination of the healthcare environment where the germicide are prepared and/or used). It is effective against norovirus and bloodborne pathogens. The FDA-cleared labels for high-level disinfection with >2% glutaraldehyde at 25ºC range from 20-90 minutes, depending upon the product based on three tier testing which includes AOAC sporicidal tests, simulated use testing with mycobacterial and in-use testing. Areas unoccupied for 7 or more days need only routine cleaning. Discard enzymatic cleaners (or detergents) after each use because they are not microbicidal and, therefore, will not retard microbial growth. Do not use processed items if the mechanical (e.g., time, temperature, pressure) or chemical (internal and/or external) indicators suggest inadequate processing. Mechanically clean reusable accessories inserted into endoscopes (e.g., biopsy forceps or other cutting instruments) that break the mucosal barrier (e.g., ultrasonically clean biopsy forceps) and then sterilize these items between each patient. Decreasing order of resistance of microorganisms to disinfection and sterilization and the level of disinfection or sterilization, Table 4. No recommendation is made about routinely performing microbiologic testing of either endoscopes or rinse water for quality assurance purposes. Use an FDA-cleared sterilant or high-level disinfectant for sterilization or high-level disinfection (, After cleaning, use formulations containing glutaraldehyde, glutaraldehyde with phenol/phenate, ortho-phthalaldehyde, hydrogen peroxide, and both hydrogen peroxide and peracetic acid to achieve high-level disinfection followed by rinsing and drying (see. The best compound for the preparation of chlorine solutions for disinfection is household bleach (also known by other names such as Chlorox®, Eau-de-Javel). Keep disinfectants out of the reach of children. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Category II”, prepare the disinfectant correctly to achieve the manufacturer’s recommended use-dilution; and. Periodically review policies and procedures for sterilization. To minimize the possibility of dispersing the virus through the air, do not shake dirty laundry. Disinfect protected surfaces at the end of the day or if visibly soiled. Gloves and gowns should be removed carefully to avoid contamination of the wearer and the surrounding area. Follow the sterilization times, temperatures, and other operating parameters (e.g., gas concentration, humidity) recommended by the manufacturers of the instruments, the sterilizer, and the container or wrap used, and that are consistent with guidelines published by government agencies and professional organizations. Disinfect (or clean) environmental surfaces on a regular basis (e.g., daily, three times per week) and when surfaces are visibly soiled. Ensure that the detergents or enzymatic cleaners selected are compatible with the metals and other materials used in medical instruments. It is a broad-spectrum disinfectant that is effective for the disinfection of viruses, bacteria, fungi, and mycobacterium. Extend exposure times beyond the minimum effective time for disinfecting semicritical patient-care equipment cautiously and conservatively because extended exposure to a high-level disinfectant is more likely to damage delicate and intricate instruments such as flexible endoscopes. For each sterilization cycle, record the type of sterilizer and cycle used; the load identification number; the load contents; the exposure parameters (e.g., time and temperature); the operator’s name or initials; and the results of mechanical, chemical, and biological monitoring. Do not use the carrying case designed to transport clean and reprocessed endoscopes outside of the healthcare environment to store an endoscope or to transport the instrument within the healthcare environment. Clean and disinfect the immediate workspace used. Wash your hands immediately after removing gloves and after contact with a person who is sick. Unresolved issue. Critical items that have been sterilized by the peracetic acid immersion process must be used immediately (i.e., items are not completely protected from contamination, making long-term storage unacceptable). Use air-exchange equipment (e.g., the ventilation system, out-exhaust ducts) to minimize exposure of all persons to potentially toxic vapors (e.g., glutaraldehyde vapor). To receive email updates about this page, enter your email address: Guideline for Disinfection and Sterilization in Healthcare Facilities (2008), 3. This is known as the “contact time” for disinfection. To achieve and maintain competency, train each member of the staff that reprocesses semicritical and/or critical instruments as follows: Compare the reprocessing instructions (e.g., for the appropriate use of endoscope connectors, the capping/noncapping of specific lumens) provided by the instrument manufacturer and the sterilizer manufacturer and resolve any conflicting recommendations by communicating with both manufacturers.
