Conspicuous vs customary location of hand hygiene agent dispensers on alcohol-based hand hygiene product usage in an intensive care unit

Hand washing is considered the single most important nosocomial infection-control strategy, yet compliance rarely meets levels recommended by infection control authorities. To determine whether placement of hand hygiene foam dispensers in more conspicuous positions and closer proximity to patients would increase use of infection control agents as measured by volume of product used. Further, to ascertain the influence of dispenser placement vs the number of dispensers available on usage by volume. This prospective, observational study conducted in an intensive care unit was composed of three observation periods. A control period with standard agent dispenser location (8 dispensers) was followed by two experimental periods: (1) "conspicuous and immediate proximity to patient" placement (16 dispensers) and (2) standard locations with a dramatic increase in the number of dispensers (36 dispensers). Volume of use for alcohol-based hand hygiene agent during the three observation periods revealed a statistically significant increase in daily consumption after conspicuous and proximate positioning of dispensers (P
