What is the main purpose of hand hygiene in a healthcare setting?

The main purpose of hand hygiene in a healthcare setting is to prevent infection transmission. This practice is crucial because healthcare environments often expose patients to a variety of pathogens, which can lead to healthcare-associated infections (HAIs). By performing proper hand hygiene, healthcare providers significantly reduce the number of microorganisms on their hands, which helps to protect both patients and themselves from infections.

Regular and effective handwashing or the use of hand sanitizers interrupts the chain of infection, decreasing the likelihood of pathogens being transferred between patients, staff, and surfaces. This practice is vital, particularly in high-risk areas such as surgical units, intensive care units, and during patient interactions, where the immune system of patients may already be compromised. Thus, the focus on prevention through proper hand hygiene is a fundamental aspect of healthcare that directly influences patient safety and health outcomes.
