BACKGROUND: The communication of health and risk information is an integral part of patient-physician interaction. Effective communication of risk information for cardiovascular diseases and diabetes has been shown to improve medication adherence, increase physical activity levels, and improve dietary control. Patients who understand their risk profile are better able to work towards modifying their lifestyle behaviours as part of a shared decision-making process with physicians. This scoping review examines the evidence on patient-physician risk communication strategies, approaches and interventions for CVDs and diabetes management in primary care and secondary outpatient settings. METHODS: A comprehensive database search for quantitative and qualitative studies was conducted in PubMed, Embase, Web of Science, Scopus, CINAHL, PsycINFO, and Cochrane Library from 1st January 2000 to 3rd October 2023. Two reviewers independently performed the screening of articles. Studies that report on patient-physician risk communication processes were included. Data were extracted and analysed using descriptive summaries and narrative synthesis. Results are reported in accordance with PRISMA-ScR guidelines. Included articles were appraised for quality following JBI critical appraisal and MMAT tools. RESULTS: A total of 8378 articles published between 1st Jan 2000 to 3rd October 2023 were screened. After a full-text review of 88 articles, a total of 30 articles, consisting of 15 qualitative, 14 quantitative and 1 mixed method studies were included. Common areas of inquiry among articles include: (1) understanding and recalling risk information, (2) strategies and approaches used by physicians to communicate risk, and (3) interventions to improve the communication of risk. Studies reveal how physicians use a range of strategies, approaches and interventions to discuss risk with patients. We present and discuss each theme narratively in detail. CONCLUSIONS: There is a critical need for further research into risk communication strategies for cardiovascular diseases (CVDs) and diabetes, with a focus on developing targeted approaches that enhance patients' understanding of their risk profiles. Evidence-based guidelines should assist healthcare professionals improve risk communication within clinical settings, with the goal of facilitating patient comprehension of health risks that can sustain lifestyle changes. Misalignment in communication may lead to dissatisfaction and confusion, which may impede the effective management of chronic conditions.
