ObjectiveTo identify the competency profile of advanced practice nurses involved in the care process of cancer patients. MethodsCross-sectional and descriptive study. The study included all nurses involved in the cancer patient care process in a tertiary hospital in Barcelona. Competence profile data were collected using the instrument for defining the role of the advanced practice nurse (APRD), as well as sociodemographic and occupational variables. Sociodemographic and occupational data were compared against the performance of advanced practice activities. ResultsA total of 29 (82.9%) nurses participated with a mean age of 42.6±12.54 years. 9 (31%) nurses were identified as meeting the standard in all 6 domains on the APRD scale to be considered advanced practice nurses. Of these 9 (31%) nurses, 7 (24.1%) met the training standards required by the International Council of Nurses (ICN) with an official master’s degree and 2 (6.9%) with a PhD. ConclusionsThere are nurses who carry out their activity in the oncology field of the hospital analyzed with the EPA profile. The identification of advanced practice nurses (APNs) in our health system is essential to be able to recognize the competencies of these professionals and create specific positions that help to address chronicity, patients' quality of life, their survival, and the optimization of health resources. Our study highlights the importance of chronicity and cancer as areas for the development of the APNs.
