The association between self-perceived proficiency of personal protective equipment and objective performance: An observational study during a bioterrorism simulation drill.

Background: The recent Ebola virus disease outbreak emphasized the potential misuse of personal protective equipment (PPE) by health care workers (HCWs) during such an event. We aimed to compare self-perceived proficiency of PPE use and objective performance, and identify predictors of low compliance and PPE misuse.

Methods: An observational study combined with subjective questionnaires were carried out during a bioterror simulation drill.
