"Who's Guide to Hand Hygiene in Healthcare"

By Daniel LewisNovember 16, 2025

Hand hygiene is a cornerstone of infection prevention and control in healthcare settings. It's the first line of defense against healthcare-associated infections (HAIs), which affect millions of patients worldwide each year. The World Health Organization (WHO) and other global health bodies have established comprehensive guidelines to ensure consistent and effective hand hygiene practices among healthcare workers (HCWs). Let's delve into these guidelines and understand their significance.

World Health Organization's "Five Moments for Hand Hygiene"

The WHO's "Five Moments for Hand Hygiene" is a globally recognized standard for hand hygiene in healthcare. It's based on the idea that hand hygiene should be performed at specific times to maximize its impact on infection prevention. The five moments are:

Before touching a patient - to prevent transmission of pathogens from the HCW's hands to the patient.
Before performing a clean/aseptic procedure - to prevent transmission of pathogens from the HCW's hands to the patient's sterile body site.
After exposure to body fluids - to prevent transmission of pathogens from the HCW's contaminated hands to other patients or environments.
After touching a patient - to prevent transmission of pathogens from the patient's skin or surroundings to the HCW's hands.
After touching patient surroundings - to prevent transmission of pathogens from the HCW's hands to other patients or environments.

Hand Hygiene Techniques

Effective hand hygiene involves more than just washing hands with soap and water. The WHO recommends using an alcohol-based hand rub (ABHR) for most situations, as it's faster, more convenient, and as effective as soap and water for most hand hygiene indications. However, soap and water should be used when hands are visibly soiled or contaminated with potentially dangerous pathogens like Clostridium difficile or norovirus.

Hand Hygiene in Healthcare: WHO Guidelines & Infection Control Best Practices

Alcohol-Based Hand Rub

When using an ABHR, the WHO recommends applying the product to the palm of one hand and rubbing hands together, covering all surfaces of the hands and fingers, until they are dry. This should take around 20-30 seconds. Here's a simple breakdown:

Steps	Duration
Apply product to palm of one hand	1-2 seconds
Rub hands together	10-15 seconds
Interlace fingers and rub	2-3 seconds
Palm to palm	2-3 seconds
Backs of hands to fingers	2-3 seconds
Thumb rotation	2-3 seconds
Dry with a clean towel or air dry	15-25 seconds

Handwashing with Soap and Water

When handwashing is indicated, the WHO recommends the following steps:

Monitoring and Improving Hand Hygiene Compliance

To ensure the effectiveness of hand hygiene guidelines, regular monitoring and improvement strategies are crucial. This can involve direct observation of HCWs, use of electronic monitoring systems, and feedback mechanisms to address any identified gaps in compliance. Education and training programs also play a vital role in maintaining high levels of hand hygiene adherence.

In conclusion, hand hygiene is a critical aspect of healthcare that requires consistent, evidence-based practices. The WHO's guidelines provide a robust framework for hand hygiene in healthcare settings, promoting patient safety and reducing healthcare-associated infections. By adhering to these guidelines and continually striving to improve hand hygiene practices, healthcare facilities can significantly enhance the quality and safety of care they provide.
