Hand hygiene is one of the most important elements of infection control. The aim of hand washing is to remove transient micro-organisms, acquired through everyday tasks in the clinical setting, from the surface of the hands. Good hand hygiene protects both patients and staff.
The WHO guidelines on “Hand Hygiene in Healthcare” describe five key situations where hand washing is required (the 5 moments for hand hygiene):
- Before touching a patient
- Before a clean or aseptic procedure
- After body fluid exposure risk
- After touching a patient
- After touching patient surroundings
There are two main cleansing agents used in hand washing; alcohol-based formulations and soap & water*. For both agents however, the technique used to clean the hands is the same.
To maintain optimum hand hygiene, it is recommended that nothing is worn below the elbows (except for a plain bands), and that the fingernails are clean and trimmed.
*The use of soap & water is specifically indicated when the hands are visibly soiled or when they have come into contact with spore-forming pathogens, such as clostridium difficile
