Although gerontological nurse specialists (GNSs) are expected to contribute to integrated care, their roles remain inconsistently defined and insufficiently synthesized across healthcare systems and professional role titles. This scoping review aims to systematically map the roles of GNSs in supporting integrated care for older adults within hospital-based settings. Methods: This scoping review protocol will follow the JBI methodology for scoping reviews and will be reported in accordance with the PRISMA-ScR guidelines. Searches will be conducted in PubMed, CINAHL, Web of Science, China National Knowledge Infrastructure, and Ichushi-Web, with no date restrictions. Studies published in English, Chinese, and Japanese will be included. The review will consider studies involving nurses with recognized specialist or advanced nursing practice competence in gerontological or older-adult care and will focus on their roles in supporting integrated care for older adults within hospital-based settings and hospital-linked transitional care services. Two independent reviewers will conduct study selection and data extraction. The findings will be synthesized descriptively and presented using tabular, narrative, and diagrammatic formats. Conclusions: This review is expected to contribute to a clearer understanding of the roles of GNSs in integrated care for older adults and provide evidence to inform future nursing practice, workforce development, education, and research in gerontological integrated care. Registration: This protocol was registered within the OSF database on 19 May 2026.<\/jats:p>","DOI":"10.3390\/ijerph23080968","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T17:16:34Z","timestamp":1785172594000},"page":"968","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Roles of Hospital-Based Gerontological Nurse Specialists in Supporting Integrated Care for Older Adults: A Scoping Review Protocol"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-6837-4084","authenticated-orcid":false,"given":"Jingwen","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Advanced Gerontological Nursing, Graduate School of Nursing, Chiba University, Chiba 260-0856, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1416-9427","authenticated-orcid":false,"given":"Li","family":"Yao","sequence":"additional","affiliation":[{"name":"Department of Advanced Gerontological Nursing, Graduate School of Nursing, Chiba University, Chiba 260-0856, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhouyuan","family":"Peng","sequence":"additional","affiliation":[{"name":"Medical School, Lihu Campus, Shenzhen University, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3847-167X","authenticated-orcid":false,"given":"Kumiko","family":"Kuroda","sequence":"additional","affiliation":[{"name":"Department of Advanced Gerontological Nursing, Graduate School of Nursing, Chiba University, Chiba 260-0856, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,27]]},"reference":[{"key":"ref_1","unstructured":"Legg, S.
