Reducing the risk of infection: hand washing technique
Eyes are susceptible to infection by many organisms, including gram-negative bacilli, adenoviruses, the herpes simplex virus, and fungi. Infection puts eyes at higher risk of complications after cataract surgery.
Hand washing is the most important, fundamental principle of infection control. It must be strongly encouraged and practised by all disciplines in the health care setting.
Hand washing is required in the following situations:
- before any aseptic procedure
- before and after handling any patient
- after handling any soiled item
- before and after handling food
- whenever hands are, or even feel, soiled
- when entering and leaving a clinical area
- after using the toilet or assisting a patient in the toilet
Many health care workers are unaware of the need for frequent hand washing and that a certain technique is required for hand washing to be effective.
