Összefoglaló szövege

Hand hygiene with alcohol-based handrub is one of the most efficient tools in fighting healthcare-associated infections. The applied volume of handrub is critical for efficacy. In clinical settings, handrub is usually provided by the means of wall-mounted dispensers. Our previous study found that the dispensed amount can decrease dramatically if dispensers are not in use for a few hours.
The aim of this study was to describe a short, simple protocol for testing wall-mounted dispensers in hospitals.
In the first part of the study, dispensers in regular, daily clinical use were tested. Dispensed amount of handrub was collected after 10 minutes resting, and volume was measured. A total of 21 dispensers were tested, representing 5 different models from various manufacturers. In the second part, dispensers were investigated in laboratory environment. Samples were collected after 2, 3, 5, 10, 30 and 60 minutes. Every time point was measured in triplicates.
We found that even the same type of dispensers can perform differently. From one particular type of dispenser, 5 pieces were tested; in the worst case, after 10 minutes resting idle the dispensed amount decreased to 58% of the original volume, while other pieces of the same type did not lose volume (0% and 2%). During the second part, dispensers were defined as defective if dispensed volume decreased by more than 40% during an hour. In the case of defective dispensers, a significant decrease is detectable even after 3 minutes.
Results suggest that all dispensers should be quality checked regularly, as even the same type dispensers can perform fundamentally different in their critical function of dispensing the proper amount. In the case of defective dispensers, there is no need for time-consuming long-term assessment measurements, as the decrease can be detected in minutes.
