Abusive Supervision and Its Relationship With Nursing Workforce and Patient Safety Outcomes: A Systematic Review.

Despite efforts to improve management and leadership behaviors among nurse managers, studies have shown the pervasive nature of abusive supervision in nursing practice, with strong evidence linking this type of behavior to reduced work productivity among nurses. This systematic review aimed to appraise and synthesize peer-reviewed studies that examine nurse-related and patient safety outcomes associated with abusive supervision. The review searched nursing literature from five databases (PubMed, CINAHL, Scopus, Web of Science, and PsycINFO) between August and November 2022. A total of 21 relevant studies were identified, with the Abusive Supervision Scale being the most frequently used measurement tool. Through content analysis, the review identified 29 outcomes which were categorized into six groups: (a) affective-based, (b) behavior/performance-based, (c) relationship-based, (d) cognitive-based, (e) health and well-being, and (f) nursing care. In addition, 10 mediators were identified and grouped into three categories: (a) affective-based, (b) motivation-based, and (c) health and well-being. The review findings provide compelling evidence regarding the detrimental effects of abusive supervision in the nursing workforce. Moreover, the review emphasizes the need for further research to explore how such behavior can impact patient safety outcomes. To address abusive supervision, it is crucial to promote positive behaviors among nurse managers through human resource mechanisms, relevant rules and policies, and theory-driven leadership development programs.
