The study accessed the accuracy of an innovative hand hygiene monitoring tool, the Sani Nudge hand hygiene solution. It was administered by two test nurses performing clinical standard tasks while being observed by two infection preventionists.

 Study highlights included:

  • All hand hygiene systems should be validated but industry standards are needed.
  • Accuracy of hand hygiene systems can be measured with only few resources available.
  • An independent-event approach is feasible to perform clinical validation.
  • Electronic and observed counting of hand hygiene opportunities and events matched.
