Which of the following is a critical factor in infection control?

Regular change of personal protective equipment (PPE) is a critical factor in infection control because PPE is designed to protect the healthcare worker from exposure to infections, and its effectiveness diminishes over time or with use. When PPE becomes contaminated, worn, or damaged, it can no longer effectively serve its purpose, potentially leading to the risk of pathogens being transmitted to both patients and healthcare personnel. Ensuring that PPE is changed regularly helps to maintain a barrier against infections, thereby reducing the likelihood of spreading pathogens in a healthcare environment.

Infection control relies on consistently using PPE that is clean and in good condition, as this is essential for preventing the transmission of infectious agents. By adhering to protocols that include regular changing of PPE, healthcare workers contribute significantly to maintaining a safe environment for both themselves and their patients.
