Making sure the data that our system generates fully represents reality is a top priority at Sani nudge. Yesterday our validation team was at Bispebjerg hospital in Denmark to compare our hand hygiene monitoring system to direct observations. Nurses from the hospital made the observations while a hygiene responsible nurse performed 25 different tasks in different locations around the ward. We not only do this to provide valid data, but also to ensure that the nurses and quality managers understand how to best use the system. We are proud to claim that we are the only system available that can cover 100% of all areas with 100% validity.
