Abstract
Several Canadian provincial cancer agencies have adopted a nurse-led model of patient navigation to decrease care fragmentation in the system. The scope of competencies of the oncology nurse navigator (ONN) in Canada has evolved over the years in response to emerging cancer care challenges. This integrative review aimed to outline the scope of competencies of the ONN role in Canada. Three databases were searched since its inception to identify Canadian studies or theoretical papers on the role of ONNs. The search yielded 62 articles of which 39 were included in the review. Three interdependent role domains were identified. The first domain of care coordinator highlighted the ONN as a coordinator of health and practical needs along the care journey. The second framed the ONN as a change agent, through increasing patients' health literacy, creating partnerships, and trusting relationships. ONNs were also described as a supporter of wellbeing, or a champion of emotional, multidimensional needs, and a transformer of the context of care. All domains were central to the navigator's success in addressing inequities in care and improving patient outcomes across care settings.
