Objective: To review the current evidence on shared decision-making (SDM) and patient decision aids (PDAs) for patients with peripheral arterial disease (PAD), focusing on application characteristics, intervention effects, and implementation factors to inform clinical decision support models. Methods: A scoping review was conducted following the Joanna Briggs Institute (JBI) framework and PRISMA-ScR guidelines. A systematic search was performed in eight Chinese and English databases, including PubMed, Embase, the Cochrane Library, CINAHL, CNKI, Wanfang, VIP, and the China Biomedical Literature Database, up to 2025. Eligible studies included randomized controlled trials, cross-sectional studies, qualitative studies, and mixed-methods studies. Data were extracted and descriptively synthesized. Results: Fifteen studies published between 2011 and 2025 were included, mainly from Europe, North America, and Asia. Studies explored SDM preferences, the development and application of PDAs, decision support tools, SDM training, multimedia decision-making interventions, and patients’ experiences. SDM and PDAs improved patient knowledge, participation, decision quality, and satisfaction, while reducing decisional conflict and negative emotions. Implementation was affected by time constraints, information complexity, provider–patient communication, and healthcare system factors. Conclusion: SDM and PDA research in PAD is increasing; however, tool standardization and clinical integration remain limited. Future research should develop patient-centered decision-support tools and promote nurse-led SDM models to improve long-term PAD management and patient decision-making experiences.
