Introduction
Ignaz Semmelweis discovered the importance of hand hygiene in 1858, and 150 years later, it was the Semmelweis University (SU) in Budapest that first adapted a digital tool to effectively teach proper hand disinfection technique. The Department of Surgical Research and Techniques at SU began to employ a UV dye-based, computer-imaging empowered device after it received the 1st ICPIC Innovation Academy Award.
