The scenario involves the introduction of a new hospital disinfectant with a 3-minute contact time, intended for use across patient care areas, but with concerns raised by Environmental Services about its high cost. The infection preventionist’s advice must balance infection control efficacy with cost management, adhering to principles outlined by the Certification Board of Infection Control and Epidemiology (CBIC) and evidence-based practices. The goal is to optimize the disinfectant’s use while ensuring a safe environment. Let’s evaluate each option:
A. Use the new disinfectant for patient washrooms only: Limiting the disinfectant to patient washrooms focuses its use on high-touch, high-risk areas where pathogens (e.g., Clostridioides difficile, norovirus) may be prevalent. However, this approach restricts the disinfectant’s application to a specific area, potentially leaving other patient care surfaces (e.g., bed rails, tables) vulnerable to contamination. While cost-saving, it does not address the broad infection control needs across all patient care areas, making it an incomplete strategy.
B. Use detergents on the floors in patient rooms: Detergents are cleaning agents that remove dirt and organic material but lack the antimicrobial properties of disinfectants. Floors in patient rooms can harbor pathogens, but they are generally considered lower-risk surfaces compared to high-touch areas (e.g., bed rails, doorknobs). Using detergents instead of the new disinfectant on floors could reduce costs but compromises infection control, as floors may still contribute to environmental transmission (e.g., via shoes or equipment). This option is not optimal given the availability of an effective disinfectant.
C. Use detergents on smooth horizontal surfaces: Smooth horizontal surfaces (e.g., tables, counters, overbed tables) are common sites for pathogen accumulation and transmission in patient rooms. Using detergents to clean these surfaces removes organic material, which is a critical first step before disinfection. If the 3-minute contact time disinfectant is reserved for high-touch or high-risk surfaces (e.g., bed rails, call buttons) where disinfection is most critical, this approach maximizes the disinfectant’s efficacy while reducing its overall use and cost. This strategy aligns with CBIC guidelines, which emphasize a two-step process (cleaning followed by disinfection) and targeted use of resources, making it a practical and cost-effective recommendation.
D. Use new disinfectant for all surfaces in the patient room: Using the disinfectant on all surfaces ensures comprehensive pathogen reduction but increases consumption and cost, which is a concern for Environmental Services. While the 3-minute contact time suggests efficiency, overusing the disinfectant on low-risk surfaces (e.g., floors, walls) may not provide proportional infection control benefits and could strain the budget. This approach does not address the cost concern and is less strategic than targeting high-risk areas.
The best advice is C, using detergents on smooth horizontal surfaces to handle routine cleaning, while reserving the new disinfectant for high-touch or high-risk areas where its antimicrobial action is most needed. This optimizes infection prevention, aligns with CBIC’s emphasis on evidence-based environmental cleaning, and addresses the cost concern by reducing unnecessary disinfectant use. The infection preventionist should also recommend a risk assessment to identify priority surfaces for disinfectant application.
