Hand care for healthcare workers

Good hygiene practice and prevention of cross infection are important for healthcare workers working in hospitals, clinics, rest care facilities and private homes.

Why is hand care important?

Hand care is important because healthcare workers are prone to hand dermatitis. This is mostly due to contact with irritants during frequent hand washing or cleaning using aggressive disinfectants and detergents. The use of surgical gloves may also cause dermatitis in some individuals.

Exposure to irritants at home or during recreation may exacerbate the problem. Chemicals, extremes of temperature and humidity, mechanical injury (e.g. rough surfaces and friction), plants, paints, some foods and ultraviolet rays, for example, may injure the skin.

The skin barrier may be disrupted by:

Disruption of the skin barrier manifests as frank eczema or irritant contact dermatitis. Damaged skin is then susceptible to bacterial infection and development of allergies (contact allergic dermatitis), aside from being itchy, sore and less supple.

Dermatitis is most likely in those with pre-existing sensitive skin or who have atopic dermatitis in other sites.

Bacterial infection is usually caused by Staphylococcus aureus and/or Streptococcus pyogenes. Hand dermatitis and wet work also predisposes to yeast infection, usually presenting as paronychia infected by Candida albicans or as intertrigo between the fingers.

Hand skin preservation tips

Sanitisers

Evidence-based Cochrane reviews reveal that alcohol-based hand rubs are superior to conventional hand washing for reducing transmission of infections in hospitals and healthcare services. They can also minimise irritation compared with soap and water.

Gloves

Gloves provide some barrier for the skin but no one glove will resist all chemicals indefinitely. Choosing the right glove design and construction will provide the best protection, provided it also fits well. Similarly, protection against mechanical risk varies with different gloves providing different strengths of abrasion, blade cut, tear and puncture resistance.

Healthcare facilities often have a health and safety officer with knowledge about suitable gloves. Safety shops also offer advice and a wide choice.

What investigations should be done?

If hand eczema is slow to improve, seek a referral to a dermatologist for patch tests. Patch tests help decide if a contact allergy is contributing. About 60% of patients with chronic hand eczema have one or more positive contact allergens on patch testing. Loss of barrier function due to irritant contact dermatitis increases the risk of developing a contact allergy.

Common occupational allergens in healthcare workers include nickel, perfume/fragrance, rubber antioxidants, antiseptics, antibacterial soap and preservatives.

Latex allergy results in immediate redness and swelling of the hands when donning gloves. This is tested by prick tests and specific IgE RAST tests.
