Handwashing in healthcare workers: accessibility of sink location does not improve compliance.
In spite of its importance, handwashing frequency in healthcare workers is generally low. The rebuilding and relocation of an 800-bed tertiary referral hospital on the same campus allowed assessment of the impact of easy accessibility to sinks on handwashing compliance. The new hospital design ensured that no clinical activity could occur more than 5 m (usually much less) from a sink. In the old hospital, clinical staff were often up to 30 m from a sink. Covert observation of nursing staff was undertaken in intensive care, infectious diseases, internal medicine and urology wards, over a total of 24 h during three consecutive days, two months before and one and 10 months after relocation to the new hospital. In all areas, handwashing compliance was greater before than after-patient contact. Initial increases (9-24%) in after-patient contact handwashing frequency following patient contact were demonstrated in units of both high and low clinical care activity one month after relocation. However, no sustained clinically significant improvement could be demonstrated nine months later. Glove use was shown to diminish compliance with handwashing protocols by as much as 25%. Improved accessibility to sinks does not lead to an improvement in healthcare workers' handwashing compliance.
