Background/scope: The Clinical Nurse Specialist in Nutrition is a professional capable of providing specialist clinical assistance and leadership-related clinical nutrition. To date, although their role has already been identified, there is still uncertainty about how this figure can actually fit into the various global health systems. The purpose of this review is to clarify and define the role of this professional aimed at analysing clinical experiences and data from nutrition scientific societies.
Methodology: A systematic literature review was conducted using the Prisma Statement in the Cochrane Library databases and subsequently in PubMed, Embase, CINAHL, Scopus and Web of Science. In addition, a manual search of studies published in Google Scholar was conducted for the analysis of 'grey literature'. Out of 2,348 identified records, 21 studies were included in the present review.
Results: The development of specific training, certification and qualification protection courses is contributing to the development of this professional in various hospital and community clinical contexts. The clinical experiences identified have shown that this figure is able to provide specialist assistance by offering high levels of safety, efficacy and quality of the care provided.
Conclusions/ implications for nursing: The implementation of nurse nutrition specialist, to date, is still limited at the global level, and training programmes coordinated between scientific societies and nursing universities could be the basis for the development of this specialization in countries where today this figure is not yet present.
