Potential for exposure to pathogens: High-touch surfaces (e.g., bed rails) require more frequent and rigorous environmental cleaning than low-touch surfaces (e.g., walls).Įvery facility should develop cleaning schedules, including: Vulnerability of patients to infection: Surfaces and items in care areas containing vulnerable patients (e.g., immunosuppressed) require more frequent and rigorous environmental cleaning than surface and items in areas with less vulnerable patients. Probability of contamination: Heavily contaminated surfaces and items require more frequent and thorough environmental cleaning than moderately contaminated surfaces, which in turn require more frequent and rigorous environmental cleaning than lightly or non-contaminated surfaces and items. Risk-Based Environmental Cleaning Frequency Principles This risk-based approach is outlined in Appendix A – Risk-assessment for determining environmental cleaning method and frequency. Risk determines cleaning frequency, method, and process in routine and contingency cleaning schedules for all patient care areas. These three elements combine to determine low, moderate, and high risk-more frequent and rigorous (with a different method or process) environmental cleaning is required in areas with high risk.
vulnerability of the patients to infection.
The determination of environmental cleaning procedures for individual patient care areas, including frequency, method, and process, should be based on the risk of pathogen transmission. This chapter provides the current best practices for environmental cleaning procedures in patient care areas, as well as cleaning for specific situations (e.g., blood spills) and for noncritical patient care equipment see summary in Appendix B1 – Cleaning procedure summaries for general patient areas and Appendix B2 – Cleaning procedure summaries for specialized patient areas.
