Utilizing an interview method to estimate potential bias in silent observer hand hygiene observations

Published:December 01, 2022DOI:


      • Healthcare worker recall of hand hygiene audit.
      • Estimates potential bias in hand hygiene observations.
      • Cost effective approach to determine anonymity of hand hygiene observers.
      Interviewed health care workers to determine whether they had noticed a silent hand hygiene observer, thereby determining the legitimacy of the silent observers. Data supported the observers were typically unseen, and potential observer bias had a negligible role in hand hygiene compliance.
