Introduction Exploring the research landscape in shared decision-making (SDM) and type 2 diabetes mellitus (T2DM) can guide clinicians, researchers, and policymakers by shedding light on the most influential studies, ultimately contributing to the development of evidence-based practices for improving patient-centered care and outcomes in the management of T2DM.

Methods We systematically searched the Web of Science Core Collection on December 1, 2023, to retrieve studies related to SDM in T2DM published from 2003 to 2023, using Bibliometrix R- package and ’biblioshiny’ to analyze annual scientific production, countries, institutions, journals, authors, citations, collaborations, keywords, and trending topics.

Results 344 studies were identified, with an annual growth rate of 20.4%. The United States emerged as the predominant contributor (n=166), with Mayo Clinic ranking first (n=53). Patient Education and Counseling [IF= 3.5] published the most studies (n=17). Montori V. participated in most studies (n=29), and the most cited document was ’Grundy SM, 2019, J Am Coll Cardiol’, a clinical guideline (n=1165). The most frequent keywords were ’primary care,’ ’adherence,’ ’cardiovascular disease,’ and ’self-management.’ The most trending topic was ’medication adherence.’ Roughly 77% of the international collaboration was within Europe, followed by Europe-North America (18%).

Discussion Publications concerning SDM and T2DM are increasing, with medication adherence as the main topic. However, there needs to be more representation from regions outside of Europe and North America due to the limitation of cultural and socioeconomic diversity and bias in research priorities.

Conclusion This bibliometric review identifies SDM and T2DM research trends and underscores the need for greater global inclusivity. By fostering collaboration and knowledge exchange across borders, we can work towards enhancing patient-centered care and improving outcomes for individuals living with T2DM worldwide.
