The study which was divided into three phrases aimed to determine if a multimodal strategy, consisting of light-guided nudging and data-driven performance feedback on group and individual levels, can be used in a clinical context as a supporting tool to improve HHC among HCWs.Study highlights included:

  • Doctors (surgeons) have lower baseline hand hygiene compliance than nurses
  • Light-guided nudging and data-driven performance feedback improve compliance
  • Individual performance feedback might be more effective than group feedback
  • The Sani Nudge system detects more opportunities than using manual observations
  • Nurses and doctors disinfect hands more often after rather than before patient contact
