Leadership research in healthcare: A realist review

Being largely considered a human right, healthcare needs leaders who are able to make choices and to set directions. Following the recommendations expressed by Gilmartin and D'Aunno's review and roadmap compiled in 2008, today, it is important to acknowledge researchers' contributions to outline this landscape. The realist review of 77 publications answered questions such as "what works, for whom, and in which circumstances" highlighting: the effectiveness and acceptance of transformational and collaborative approaches; professionalism, expertise, and good task delegation within operational teams; distributed leadership, relationships, and social responsibility at a systemic level. The relevancy and need of leadership development programs, framed within a wider strategy, emerged. Nonetheless, gaps still exist and require further investigation: particular needs in public vs. private contexts; professionals' and women's differentiating characters; generational gaps; associations between leadership and recruitment HR practices research; how (and if) leaders (should) influence the organizational culture and values; and developing countries specific challenges. Also, a greater proportion of relevant findings should be drawn by empirical and more rigorous studies. Finally, a major attention could be paid to interactions happening at the team, organizational, and systemic level among different leaders and among leaders, followers and external actors.
