Introduction to Hand Hygiene
Why Hand Hygiene Matters
Hand hygiene is the single most effective intervention for preventing healthcare-associated infections (HAIs) and reducing antimicrobial resistance. Healthcare workers’ hands are the primary vehicle for transmitting pathogens between patients, making proper hand hygiene critical for patient safety and quality care delivery.
Historical Context: The importance of hand hygiene was first demonstrated by Ignaz Semmelweis in 1847, who showed that handwashing with chlorinated lime solutions reduced mortality rates in maternity wards from 18% to less than 2%. This foundational discovery laid the groundwork for modern infection prevention practices.
Current Significance: Despite overwhelming evidence supporting hand hygiene, compliance rates among healthcare workers globally remain suboptimal, ranging from 30-70%. This gap between knowledge and practice represents a significant opportunity for improving patient outcomes and reducing healthcare costs associated with preventable infections.
Memory Aid: CLEAN
- Compliance saves lives
- Lather for 15-30 seconds
- Every patient contact
- Alcohol-based rub when available
- Nails should be short and clean
Types of Hand Hygiene
1. Routine Hand Hygiene
Purpose: Remove transient microorganisms and some resident flora
Duration: 15-30 seconds with soap and water or alcohol-based hand rub
Indications:
- Before and after patient contact
- Before clean/aseptic procedures
- After body fluid exposure risk
- After touching patient surroundings
2. Antiseptic Hand Hygiene
Purpose: Reduce transient and some resident microorganisms
Duration: 2-5 minutes with antiseptic agent
Indications:
- Before invasive procedures
- In outbreak situations
- When caring for immunocompromised patients
- In high-risk units (ICU, OR)
3. Surgical Hand Antisepsis
Purpose: Eliminate transient flora and reduce resident flora
Duration: 2-5 minutes initial scrub, 2-3 minutes subsequent
Key Features:
- Systematic approach from fingertips to elbows
- Use of brush or sponge for mechanical action
- Sterile towels for drying
- Persistent antimicrobial activity
4. Protective Hand Hygiene
Purpose: Protect healthcare worker from exposure
Components: Proper glove use with hand hygiene
Critical Points:
- Hand hygiene before gloving
- Proper glove removal technique
- Hand hygiene after glove removal
- Understanding that gloves are not 100% protective

WHO 5 Moments of Hand Hygiene
The Science Behind the 5 Moments
The WHO 5 Moments framework is based on extensive research demonstrating that healthcare workers’ hands become contaminated at predictable points during patient care. These five critical moments represent opportunities to interrupt pathogen transmission and protect both patients and healthcare workers.
Patient Protection
Moments 1, 2, and 3 protect the patient from harmful microorganisms, including those from the healthcare worker and the environment.
Healthcare Worker Protection
Moments 4 and 5 protect the healthcare worker and healthcare environment from patient microorganisms.
Moment 1: Before Touching a Patient
When:
- • Before any direct patient contact
- • Before putting on gloves for patient contact
- • When moving from contaminated to clean body site
Examples:
- • Shaking hands, helping patient move
- • Clinical examination, taking vital signs
- • Providing comfort or reassurance
Moment 2: Before Clean/Aseptic Procedures
When:
- • Before any invasive procedure
- • Before handling invasive medical devices
- • Before preparing medications
Examples:
- • IV insertion, urinary catheterization
- • Wound dressing changes
- • Administering injections
Moment 3: After Body Fluid Exposure Risk
When:
- • After any contact with body fluids
- • After handling contaminated items
- • After removing gloves
Examples:
- • After handling specimens, secretions
- • After wound care or suctioning
- • After cleaning up spills
Moment 4: After Touching a Patient
When:
- • After any direct patient contact
- • After removing gloves from patient contact
- • Before touching anything else
Examples:
- • After physical examination
- • After assisting with ADLs
- • After helping patient with mobility
Moment 5: After Touching Patient Surroundings
When:
- • After contact with surfaces near patient
- • After handling patient equipment
- • Before leaving patient area
Examples:
- • After touching bed rails, monitors
- • After handling IV pumps, ventilators
- • After touching bedside table, chair
Memory Aid: BEFORE and AFTER
BEFORE (Patient Protection)
- 1. Before patient contact
- 2. Before clean/aseptic procedures
AFTER (Self & Environment Protection)
- 3. After body fluid exposure
- 4. After patient contact
- 5. After touching patient surroundings
