"Five Key Moments for Hand Hygiene: When & Why"

Understanding the Five Moments for Hand Hygiene

Hand hygiene is a cornerstone of infection prevention and control. It's a simple yet powerful measure that helps prevent the spread of healthcare-associated infections. The World Health Organization (WHO) has outlined five key moments when healthcare workers should perform hand hygiene. Let's delve into these critical moments, their importance, and the best practices for each.

1. Before Patient Contact

The first moment for hand hygiene is before touching a patient. This is to ensure that healthcare workers do not transmit their own microorganisms to the patient. It's crucial because patients, especially those with weakened immune systems, are highly susceptible to infections.

• When: Before any patient contact, including approaching the bedside.
• How: Use an alcohol-based hand rub (ABHR) or soap and water if hands are visibly soiled.

2. After Patient Contact

After touching a patient, it's essential to clean your hands to remove any microorganisms that may have been acquired from the patient. This helps prevent the spread of pathogens to other patients or surfaces.

• When: After touching a patient, including their intact skin.
• How: Use an ABHR or soap and water if hands are visibly soiled.

3. Before Aseptic Procedures

Before performing an aseptic procedure, such as inserting a central venous catheter or performing wound care, it's crucial to clean your hands to minimize the risk of infection.

• When: Before starting an aseptic procedure.
• How: Use soap and water, followed by an ABHR. Gloves should also be worn during the procedure.

4. After Exposure to Body Fluids

After exposure to blood, bodily fluids, secretions, or excretions, hand hygiene is necessary to remove any microorganisms acquired from these fluids.

• When: After exposure to blood or bodily fluids.
• How: Use soap and water, followed by an ABHR. Gloves should be worn during the exposure and removed using appropriate techniques.

5. After Contact with Patient Surroundings

The final moment for hand hygiene is after touching a patient's immediate surroundings, such as their bed, bedside table, or equipment. This is to prevent the transmission of microorganisms from the environment to your hands and then to another patient or surface.

• When: After touching a patient's surroundings.
• How: Use an ABHR or soap and water if hands are visibly soiled.
