Prevalence, Antecedents, and Consequences of Workplace Bullying among Nurses—A Summary of Reviews

Despite over 25 years of extensive research about the workplace bullying phenomenon in various disciplines, there have been mixed conclusions about its prevalence, antecedents, and consequences among nurses reported by multiple systematic reviews. This summary review used the Cochrane’s Overview of Reviews method to examine the prevalence, antecedents, coping behaviors, and consequences of workplace bullying among nurses to understand the interplay of these variables in healthcare workplace contexts. A total of 12 systematic reviews published between 2013 and 2020 were included based on the eligibility criteria. There were differences in workplace bullying prevalence across different reviews, ranging from 1 to 90.4%, but a more recent review estimated the pooled prevalence at 26.3%. This review identified at least five main types of antecedents for workplace bullying: demographics, personality, organizational culture, work characteristics, and leadership and hierarchy. Workplace bullying affected nurses, organizational outcomes, and patient safety. This review proposes an integrative model to explain workplace bullying among nurses and highlights the need for more studies to evaluate interventions to address this phenomenon.
