[Role of the nurse in research]

In the last decade, the participation of nurses in research has increased and different roles have emerged in this area: clinical research nurse, research nurse, research support nurse and research consumer nurse. In this regard, the terms clinical research nurse and research nurse are often confused and used interchangeably. However, these are four different profiles, because the functions, training requirements, skills and responsibilities of these vary considerably and that is why it seems interesting to define the contents and competencies of each of them.
