Which infection control measure effectively reduces the risk of healthcare-associated infections?

The consistent use of hand hygiene protocols is a foundational infection control measure that significantly reduces the risk of healthcare-associated infections (HAIs). Hand hygiene includes thorough handwashing with soap and water or the use of alcohol-based hand sanitizers, which are effective in eliminating pathogens that can be transmitted between healthcare providers, patients, and the environment.

Effective hand hygiene practices are critical in interrupting the transmission of bacteria, viruses, and other microorganisms that can lead to infections acquired during healthcare delivery. Studies consistently show that when healthcare workers adhere to recommended hand hygiene guidelines, the rates of HAIs decrease, demonstrating the importance of this measure in protecting patient health and enhancing overall safety in healthcare settings.

In contrast, the other options do not contribute positively to reducing infection risks. Using personal medications may not address infection prevention directly, and increasing patient visits could potentially elevate infection risk if proper precautions aren't taken. Reducing staff training is counterproductive, as well-trained staff are essential for implementing effective infection control practices.
