| Popis: | Hand hygiene is important in the prevention of healthcare-associated infection in hospitals, but the compliance rate of healthcare workers for hand hygiene is lower than expected. Hand hygiene compliance is usually monitored employing visual methods that are open to the Hawthorne effect and limited in terms of time and place. An automated monitoring system may provide the hand-hygiene compliance rate automatically and continuously, without suffering from the Hawthorne effect. An automated monitoring system may also improve hand hygiene by providing feedback data and real-time reminders. We report herein on an automated monitoring system that permits the tracking of hand hygiene opportunities and the disinfection compliance of healthcare workers. The aim is to establish the accuracy of the system in monitoring hand hygiene compliance and to estimate the effect of the system in promoting hand hygiene behaviour. Two studies were conducted. First, to evaluate the accuracy of hand hygiene compliance recorded by the automated monitoring system, we compared the hand hygiene compliance rate recorded by the automated monitoring system with that recorded by direct visual observation for 3 days during the same period in the same ward. For the overall period of simultaneous automated and human observations, the hand hygiene compliance rate was automatically observed to be 78% and visually observed to be 75.4%. Second, to estimate the effect of the automated monitoring system in improving health workers' compliance with hand hygiene, we installed monitoring equipment in one ward and measured the compliance rate via the automated monitoring system for 13 weeks. This study included Phase 1 with a reminder only, Phase 2 with a reminder and feedback, and Phase 3 again with a reminder only. A significant increase in hand hygiene performance was observed during phase 2, and a high rate was sustained over phase 3. In phase 1, however, there was no increase in the hand hygiene compliance rate. We found the automated monitoring system to be a useful tool for not only monitoring hand hygiene but also for improving hand hygiene compliance. |
