What action is essential before applying topical antimicrobials?

Washing hands thoroughly before applying topical antimicrobials is crucial for maintaining infection control and preventing contamination. Proper hand hygiene reduces the risk of transmitting pathogens that could worsen the infection or lead to new infections. It prepares both the healthcare provider's hands and the area where the antimicrobial will be applied, ensuring that the treatment can be effective without interference from external bacteria or contaminants.

While consulting a physician may be necessary in certain situations, it is not always essential before the application of topical antimicrobials, particularly when the practitioner has the authority and knowledge to prescribe these treatments. Applying directly from the tube without proper hygiene can introduce pathogens, and covering the area with a bandage is important but should occur after proper application and handwashing. Thus, hand hygiene stands as the foundational step in the process of applying topical antimicrobials.
