Effectiveness of a Multimodal IT Enhanced Hand Hygiene Strategy on Healthcare Associated Infections in Nursing Homes

The intervention, adapted from the WHO's multimodal strategy, incorporated IT-based components to enhance hand hygiene compliance. A one-time, 1-hour online education session via Google Meet covered the WHO's Five Moments and seven-step handwashing technique, with real-time feedback using fluorescent dye and UV light. Post-session videos were available on tablets for review. Visual reminders, such as screensavers and digital posters, reinforced learning. Smart sanitizer dispensers with seven-step lights and a 20-second countdown were installed at five key sites, RFID-linked to staff badges for automatic tracking. Monthly performance data were shared via bulletin boards and LINE, with SMS feedback to top and bottom performers. Daily audio reminders played at 9 a.m. and 5 p.m., and high performers were recognized in monthly meetings.
