Hand Hygiene
Definition
The practice of cleaning hands to remove pathogens, using soap and water or alcohol-based hand rub, to prevent healthcare-associated infections.
Overview
Hand hygiene is the single most important practice in preventing healthcare-associated infections. Compliance rates average only 40–60% without active improvement programs.
The two primary methods are handwashing with soap and water and alcohol-based hand rub (ABHR). Each has specific indications and techniques.
WHO Five Moments
- Before touching a patient
- Before clean or aseptic procedures
- After body fluid exposure risk
- After touching a patient
- After touching patient surroundings
Technique
Handwashing requires minimum 20 seconds of vigorous rubbing covering all surfaces. ABHR requires 20–30 seconds rubbed over all surfaces until dry.
Surgical hand antisepsis requires 2–6 minute scrub with antimicrobial soap before donning sterile gloves.
Common Errors
Inadequate duration, missing fingertips/thumbs, wearing rings or artificial nails, and applying ABHR to visibly soiled hands.
Why It Matters
Hand hygiene questions appear on CNA, MA, CST, EMT, and Paramedic exams. You must know the WHO five moments, proper technique duration, and when ABHR is insufficient.
