What is the goal of Intermediate-Level Disinfection?

• A. The destruction of bacterial spores only
• B. The destruction of viruses, mycobacteria, fungi, and vegetative bacteria
• C. The cleaning of surgical instruments
• D. The reduction of visible contamination on surfaces

Answer: (B)

The goal of Intermediate-Level Disinfection is primarily focused on the destruction of a wide range of pathogens, specifically targeting viruses, mycobacteria, fungi, and vegetative bacteria. This level of disinfection is essential in healthcare settings, particularly in surgical environments where the risk of infection from various microorganisms is heightened.

Intermediate-level disinfection effectively eliminates pathogens that pose a significant risk to patients, especially those that are resistant to low-level disinfection methods. For instance, mycobacteria are known for their resilient nature and can be more challenging to eliminate compared to standard bacteria. By ensuring these pathogens are destroyed, the process contributes significantly to patient safety.

Cleaning surgical instruments involves more than just reducing visible dirt; it must ensure that all types of potentially harmful microorganisms are adequately addressed before the instruments can be reused safely. Consequently, the methods used in this context must be capable of targeting a broad spectrum of pathogens, not just those that are visibly contaminating the instruments or surfaces.

While the destruction of bacterial spores is crucial in sterilization processes, this goes beyond the scope of intermediate-level disinfection, which does not purport to eliminate all spores effectively. Similarly, cleaning and reducing visible contamination focus on surface appearance rather than the microbial efficacy required in surgical settings. Therefore
