Effective nursing leadership has been shown to improve patient outcomes, but there has been little exploration of the factors that influence early career nurses to develop their leadership skills and adopt leadership roles. This article presents a rapid review of the literature on these factors, integrating data from 25 articles. Findings suggest that improving leadership confidence and self-efficacy, particularly in relation to system leadership, can increase nurses’ motivation for adopting leadership roles. Supportive organisations that value leadership and give nurses opportunities to exercise it are equally important. Training and education, preceptorship, peer-to-peer shadowing, modelling and mentoring can all be useful in improving leadership skills and inspiring the next generation of nurse leaders.
