Compliance with hand disinfection and its impact on hospital-acquired infections.

Hand hygiene prevents cross-infection in hospitals, but adherence to guidelines is poor among healthcare workers. Although some interventions to improve compliance have been successful, none had achieved lasting improvement until very recently. Reasons for non-compliance with recommendations occur at individual, group and institutional levels. The complexity of the process of behavioural change would suggest that the application of multimodal, multidisciplinary strategies are necessary. Both easy access to hand hygiene in a timely fashion and skin protection appear necessary prerequisites for satisfactory hand hygiene behaviour. Alcohol-based hand-rub may be superior to traditional handwashing as it requires less time, acts faster, irritates hands less often, and recently proved significantly to contribute to sustained improvement in compliance associated with decreased infection rates. This paper reviews barriers to appropriate hand hygiene and describes the results of the first successful experience of sustained hand hygiene promotion and its effectiveness on hospital-acquired infection.
