Power and leadership are intimately related. While physician leadership is widely discussed in healthcare, power has received less attention. Formal organisational leadership by physicians is increasingly common even though the evidence for the effectiveness of physician leadership is still evolving. There is an expectation of leadership by all physicians for resource stewardship. The impact of power on interprofessional education and practice needs further study. Power also shapes the profession’s attempts to address physician and learner well-being with its implications for patient care. Unfortunately, the profession is not exempt from inappropriate use of power. These observations led the authors to explore the concept and impact of power in physician leadership.
