The concept of person-centred care has emerged in Australia alongside many different descriptions in the literature without consensus on a global definition. The Australian residential aged care sector is currently redesigning its entire system. Person-centred care remains a broad and heterogeneous topic in healthcare. A clear and explicit definition of person-centred care could not be found in Australian aged care governing bodies. Examining which descriptions of person-centred care exist in residential aged care nursing practice literature can provide information to inform practice and policy. Therefore, a scoping review of published work and grey literature is being conducted guided by the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA –SCR) and Chapter 11 of the Joanna Briggs Institute (JBI) Reviewer’s 3 Manual. The aim of the scoping review is to synthesise the descriptions of person-centred care in residential aged care nursing practice. A population, concept, and context (PCC) framework has been used to develop the research question and define inclusion and exclusion criteria. The scoping review is being conducted to answer the question: What is the definition of person-centred care in residential aged care nursing practice? Evidence is being sourced from CINHAL, PubMed, Scopus, and Web of Science databases, and references from all included articles. Data will be extracted based on congruency with the eligibility and inclusion criteria, research question, and objectives of this scoping review. The PRISMA flowchart will be used to show the source selection process. Data will be mapped with a descriptive format that aligns with the PCC framework, research questions, and objectives of the review. A synopsis of descriptions will be presented. This evidence could help move person-centred care from an emerging concept to an established nursing practice in Australian residential aged care.
