Hand Hygiene
Key Points
- Hand hygiene is the most effective routine action to reduce infection transmission.
- Accepted methods are soap-and-water handwashing or alcohol-based hand sanitizer.
- Required moments include before patient contact, before aseptic/invasive tasks, after body-fluid or contaminated-surface contact, after patient/environment contact, and immediately after glove removal.
- Nail standards matter: short natural nails (tip under 0.5 inches), no artificial nails/tips, and no nail polish.
- Routine hand hygiene primarily removes transient flora acquired by contact; deep resident flora are reduced less completely.
Core Practice
Hand hygiene is applied consistently across all care settings to interrupt transmission from staff hands to patients, equipment, and surrounding surfaces. It remains necessary even when gloves are used.
Transient flora from recent contact are the most important transmission target during clinical hand hygiene. Resident flora in deeper skin layers are less fully removed, so repeated correct technique remains essential throughout shifts.
Required Care Moments
- Immediately before touching a client.
- On arrival to and departure from a patient-care unit.
- Before aseptic tasks or handling invasive devices.
- Before moving from a soiled site to a clean site on the same client.
- After touching a client or immediate surroundings.
- After blood/body-fluid or contaminated-surface contact, with or without gloves.
- Immediately after glove removal.
Nursing Interventions
- Choose soap-and-water or sanitizer according to contamination risk and facility policy.
- Use alcohol-based sanitizer for routine decontamination when hands are not visibly soiled; rub thoroughly for about 20-30 seconds.
- Use soap and water when hands are visibly soiled, after blood/body-fluid contamination, and in C. difficile care contexts.
- For C. difficile isolation care, use soap-and-water hand hygiene when entering and exiting the room per facility protocol.
- Perform a full soap-and-water wash for at least 30 seconds to improve microorganism removal.
- Enforce nail/hygiene standards for all direct-care personnel.
- Coach staff and learners that glove use never replaces hand hygiene.
- Escalate repeated noncompliance as a patient-safety risk.
