This systematic review examines servant leadership in healthcare, analyzing 55 studies to understand its conceptualization, theoretical frameworks, measurement tools, and nomological networks. Servant leadership, rooted in moral and ethical principles, emphasizes serving others and fostering personal and organizational growth. It is particularly relevant in healthcare due to the complex, multicultural, and high-stakes nature of the environment. The review highlights the Global Servant Leadership Scale as the most widely used measure, with social exchange theory as the dominant explanatory framework. Servant leadership is positively associated with various outcomes, including employee commitment, job satisfaction, and organizational performance. The study reveals that servant leadership enhances employee well-being, reduces burnout, and improves patient care. It also contributes to the development of servant leadership theory by identifying key antecedents, mediators, and moderators in healthcare settings. The review underscores the importance of integrating servant leadership into healthcare practices to achieve performance excellence and improve patient outcomes. Future research should explore under-researched areas, such as the relationship between servant leadership and patient safety, and ensure methodological rigor in studies. The findings suggest that servant leadership is a promising model for healthcare leadership, emphasizing ethical, compassionate, and supportive leadership practices.This systematic review examines servant leadership in healthcare, analyzing 55 studies to understand its conceptualization, theoretical frameworks, measurement tools, and nomological networks.
