Prior studies have demonstrated that rude behavior undermines patient safety. This study used a smartphone application to collect reports of rudeness directed toward nurses. These data were analyzed in conjunction with the hospital's hand hygiene and medication protocol compliance data as well as adverse event reports to determine if rudeness affected these safety outcomes. Participants also reported whether rudeness incidents influenced their cognition or their teamwork. Although rudeness was associated with worse self-reported cognition and teamwork, investigators did not observe differences in reported adverse events or changes in hand hygiene or medication protocol adherence related to rudeness exposure. A past PSNet perspective discussed how organizations are seeking to rehabilitate persistently disruptive clinicians.
