The only solution to measure hand hygiene compliance according to your existing guidelines

Developed and trusted by hospitals around Europe

How it works



A sensor is installed on your existing dispenser solution from where it registers each sanitation and provide positive feedback when used.



The Sani ID is permanently attached to existing name tags, from where it collects and shares each hand hygiene opportunity anonymously.



The Sani sensor is placed above the patient beds and creates an invisible zone that identifies patient contact according to WHOs guidelines.

Our Story

Anne-Mette Iversen, a clinical nurse specialist at Aarhus University Hospital in Denmark had tried to improve the hospital’s hand hygiene compliance using flyers, stickers, training and posters, nothing had worked. The flyers piled up in the staff desk drawers and her team forgot their training after just few weeks. She knew that the direct methods of observation for compliance were impacted by the “Hawthorne Effect” which made her unable to prove the impact of her team’s improvement work. The hand hygiene compliance data was unreliable, and this made her unable to understand the possible risk of infections that was placed on the patients. This frustration created Sani nudge. 

Sani nudge was the solution we needed to improve our hand hygiene culture.

Hand hygiene compliance is one of the most critical measures in healthcare for patient safety. Accurate reporting of compliance and improvement work have been proven in hundreds of peer-reviewed articles to significantly reduce the number of healthcare acquired infections.


In 2015, in order to get data and improve hand hygiene compliance in her hospital, Anne-Mette Iversen mobilized a team led by engineers, clinical professionals and behavior scientists to design the Sani nudge. The solution was able to unobtrusively monitor hand hygiene compliance before and after patient contact and in other work situations such as management of medicine. The data was used to design a nudging method to positively reinforce good hand hygiene behavior of staff. Together with Bispebjerg hospital the system was tested and modified to provide validated data and to prove lasting improvement on hand hygiene compliance.


In 2018, the system validation was completed and the solution was ready to help other hospitals improve their hand hygiene compliance. The system has since proven to sustainably triple compliance scores for thousands of healthcare workers, at a low cost to the hospital and without impacting the workflow of the staff.


The study and development of the Sani nudge hand hygiene monitoring system have been supported with 1 million euro from the Danish government.
