The state of hand rub dispensers in healthcare settings – a multicenter assessment in 19 German healthcare facilities

Even though several studies addressed the variability in dispensed volumes of hand hygiene dispensers, studies dealing with dispenser types and functionality are lacking, promoting the common but false assumption that different dispensers may be equivalent and interchangeable. Variability in dispensed volumes, coupled with frequent dispenser defects and maintenance issues, can be a major barrier to hand hygiene compliance. To support healthcare workers, more attention should be paid to 'dispenser compliance', selecting dispensers with similar volume ranges and proper maintenance.
