Background The Emergency Department (ED) is a setting where teamwork and leadership is imperative, however, the literature to date is mostly discipline (nursing or medical) specific. This scoping review aimed to map what is known about nurses’ and physicians’ conceptions of leadership in the ED to understand similarities, differences, and opportunities for leadership development and research.

Method Guided by the Joanna Briggs Institute approach, and Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Guidelines, a systematic search of three electronic databases was performed. The Mixed Methods Assessment Tool was used for quality appraisal of included articles.

Results In total, 37 articles were included. Four key findings emerged: 1) leadership was rarely explicitly defined; 2) nurse leaders tended to be characterised as agents of continuity whilst physician leaders tended to be characterised as agents of change and continuity; 3) the clarification of expectations from nurse leaders was more evident than expectations from physician leaders; and 4) leadership discourse tended to be traditional rather than contemporary.

Conclusion Despite the proliferation of studies into ED nurse, physician and interprofessional leadership, opportunities exist to integrate learnings from other sectors to strengthen the development of current and next generation of ED leaders.
