IntroductionUniversal access to preventative healthcare is essential to children’s health. Registered nurses (RN) are well positioned to deliver well-child care within primary care settings; however, RN role implementation varies widely in this sector and the scope of literature that examines the influence of organisational attributes on nursing contributions to well-child care is not well understood. The aim of this scoping review is to identify the scope and characteristics of the literature related to organisational attributes that act as barriers to, or facilitators for RN delivery of well-child care within the context of primary care in high-income countries.Methods and analysisThe Joanna Briggs Institute scoping review methodology will be used to conduct this review. Databases that will be accessed include Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE and Embase. Inclusion criteria includes articles with a focus on RNs who deliver well-child care in primary care settings. Literature that meets this inclusion criteria will be included in the study. Covidence software platform will be used to review citations and full-text articles. Titles, abstracts and full-text articles will be reviewed independently by two reviewers. Any disagreements that arise between the reviewers will be resolved through discussion, or with an additional reviewer. Data will be extracted and organised according to the dimensions outlined in the nursing care organisation conceptual framework (NCOF). Principles of the ‘best fit’ framework synthesis will guide the data analysis approach and the NCOF will act as the framework for data coding and analysis.Ethics and disseminationThis scoping review will undertake a secondary analysis of data already published and does not require ethical approval. Findings will be disseminated via peer-reviewed publications and conference presentations targeting stakeholders involved in nursing practice and the delivery of well-child care.Trial registration detailsBraithwaite, S., Tranmer, J., Lukewich, J., & Macdonald, D.
