A. Voss et Af. Widmer, NO TIME FOR HANDWASHING - HANDWASHING VERSUS ALCOHOLIC RUB - CAN WE AFFORD 100-PERCENT COMPLIANCE, Infection control and hospital epidemiology, 18(3), 1997, pp. 205-208
Handwashing is the most important and least expensive measure to preve
nt transmission of nosocomial infections. However, compliance rarely e
xceeds 40% under study conditions. Alcoholic hand disinfection (AHD) g
enerally is used in Europe. In contrast, handwashing with medicated so
ap is practiced most frequently in the United States. Healthcare worke
rs often explain the failure to comply with handwashing or AHD as due
to the limited time available for this practice. We calculated a time
consumption for handwashing and AHD in a representative model intensiv
e-care unit with 12 healthcare workers, based on different compliance
levels (40%, 60%, and 100%), duration of handwashing (40-80 seconds),
and AHD (20 seconds). Comparing the extremes of our model, given 100%
compliance, handwashing consumes 16 hours of nursing time per day shif
t, whereas AHD from a bedside dispenser requires only 3 hours (P=.01).
We conclude that 100% compliance with handwashing may interfere with
patient care and partly explains the low compliance. In contrast, AHD,
with its rapid activity, superior efficacy, and minimal time commitme
nt, allows 100% healthcare-worker compliance without interfering with
the quality of patient care.
