Little information exists regarding competencies required to function as a charge nurse. This qualitative study identified charge nurse competencies. Data sources were interviews (N = 42) with charge nurses, head nurses, staff nurses, and supervisory personnel. A total of 54 competencies were identified in four categories: clinical/technical, critical thinking, organizational and human relations skills. The charge nurses who were interviewed primarily came from medical-surgical and intensive care units. The competencies derived from their interviews reflect leadership and management skills that medical-surgical nurses need to function as effective charge nurses.
