Sani nudge is a tracking system that automatically detects the use of the sanitizer by healthcare workers while registering patient contact, thus improving hand hygiene levels, increasing patient and staff safety, and reducing healthcare-associated infections. It is small and can be affixed to existing dispensers, not impacting the existing workflow. Thanks to low-energy Bluetooth, its battery lasts for two years. It automatically and anonymously sends data every time the dispensers are used so you can track how well your workers follow hand hygiene compliance. A whole system can be installed in few hours without involving the IT team.
