Trials evaluating interventions to improve health care workers’ hand hygiene compliance use directly observed compliance as a
primary outcome measure. Observers should be blinded to the intervention and the effectiveness of blinding assessed to prevent
systematic bias. The literature has not addressed this issue, and this study describes a robust and pragmatic method for assessing
the adequacy of blinding in hand hygiene intervention trials.
Key Words: Hand hygiene; trials; blinding; training; observation; compliance; reliability.
