Application of smart healthcare in the continuum of care for type 2 diabetes mellitus: a scoping review protocol

Introduction Type 2 diabetes mellitus (T2DM) is a chronic non-communicable disease that requires long-term management to maintain blood glucose levels and prevent complications. Smart healthcare technologies have shown promising potential in enhancing self-management and treatment adherence among people with T2DM. However, current research on the use of smart healthcare in the continuum of care for T2DM showed considerable variation in intervention approaches, content and evaluation metrics, resulting in substantial heterogeneity across studies. Objectives This scoping review aims to identify recurring intervention strategies, summarise commonly reported components and outline outcome indicators in the application of smart healthcare within the continuum of care for T2DM, to inform future research and practice by healthcare professionals. Methods and analysis This scoping review will follow the methodological framework proposed by Arksey and O’Malley. A comprehensive literature search will be conducted across PubMed (National Library of Medicine), Embase (Elsevier), Cumulative Index to Nursing and Allied Health Literature (CINAHL; EBSCO), Web of Science (Clarivate Analytics), the Cochrane Library (Wiley), Scopus (Elsevier), China National Knowledge Infrastructure (CNKI; China Academic Journals (CD-ROM) Electronic Publishing House), Wanfang Data (Beijing Wanfang Data Co., Ltd.), VIP Database (Chongqing VIP Information Co., Ltd.) and Chinese Biomedicine Literature Database (CBM; Chinese Academy of Medical Sciences). The search will include studies published from the inception of each database up to 25 April 2025. Two reviewers will independently screen the literature and extract data. Any disagreements will be resolved through discussion with a third reviewer. The review will be reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. Ethics and dissemination Ethics approval is not required. Findings will be disseminated through professional networks, conference presentations and publication in a scientific journal.
