This document describes a study that explored advanced practice nurses' perceptions of their leadership capabilities. The study identified two main themes of leadership demonstrated by advanced practice nurses: patient-focused leadership and organization and system-focused leadership. Patient-focused leadership involves capabilities that directly impact patients and families, such as managing patient-centered care, coaching and educating, advocating, and initiating communication. Organization and system-focused leadership involves capabilities that directly impact nurses, healthcare providers, organizations, and the healthcare system, such as improving quality of care, enhancing nursing practice, communicating effectively, and facilitating collaboration. The study developed a model of advanced practice nurse leadership capabilities based on these themes to clearly articulate the nature and complexity of advanced practice nursing roles.
