Cost analysis of hand hygiene using antimicrobial soap and water versus an alcohol-based hand rub.

Proper hand hygiene is acknowledged as the most critical element of an adequate infection control program in the oral healthcare setting. However, adherence to proper hand hygiene protocols is often lacking. Poor compliance with hand hygiene protocols has been attributed to such factors as lack of time, hand irritation, hand dryness, forgetfulness, skepticism over importance, understaffing, perceived low risk of cross-infection, inconvenience, and the belief gloves alone offer protection. In the medical environment the use of alcohol-based hand rubs now represent the preferred method of performing hand hygiene when delivering non-surgical care. In this study we compared the costs associated with traditional hand washing against an alcohol-based hand rub protocol in the dental setting. The results indicate an alcohol-based hand rub protocol is less costly and less time consuming when compared to traditional handwashing in the dental setting, creating a new paradigm for hand hygiene in the dental office.

The water barrier function of the skin in relation to the water content of stratum corneum, pH and skin lipids. The effect of alkaline soap and syndet on dry skin in elderly, non-atopic patients.

Clinical dryness of the skin is a common problem among elderly, dermatological patients. In the present investigation, hydration, surface lipids, skin pH and water barrier function as expressed by the transepidermal water loss (TEWL) were studied in both dry and normal skin. Using these parameters, a comparison of the local effects of acid and alkaline cleansing products was made. In non-atopic elderly patients with dry skin, the TEWL values were lower than in the younger control group but higher than in the older controls. Following one week's topical therapy, the TEWL values in the patient group decreased further and approached the lower values of the older control group. At the same time the skin hydration values increased, indicating a beneficial effect on the skin barrier. An inverse relationship was demonstrated between TEWL and skin hydration. The study indicates that high TEWL values are frequently correlated with high pH, low hydration of the stratum corneum and reduced skin surface lipid content. Despite the intensive use of an acid syndet and lotion, the pH-readings increased but were still within the 'confidence limits' of the control groups.
