Exploring stakeholder perspectives on the content, delivery, and contextual delivery of shared decision-making for people living with subacromial pain syndrome: a multimethod study with future workshops and interviews

Background: Shared decision-making (SDM) is a key component in patient-centered care for people consulting health care due to chronic musculoskeletal pain, including subacromial pain syndrome (SAPS). Limited research has explored how patients, relatives, and healthcare professionals perceive the content and delivery of SDM for managing SAPS in primary care. Thus, this study aims to explore stakeholder perspectives on the content, delivery, and contextual requirements for a context-specific SDM intervention for SAPS, and to identify shared challenges and co-develop ideas to inform intervention development. Methods: We conducted three separate future workshops (patients/relatives, physiotherapists/chiropractors, and general practitioners), each consisting of structured critique, fantasy, and implementation phases. A rapid preliminary analysis of workshop data was followed by semi-structured stakeholder interviews to validate, challenge, or elaborate the findings. All data were analysed thematically using an iterative, reflexive approach. Results: Twenty-eight participants took part across three workshops: patients/relatives (n = 10), physiotherapists/chiropractors (n = 12), and general practitioners (n = 6). Six additional stakeholders provided inputs via subsequent interviews (three physiotherapists, one patient, one relative and one GP). Thematic analysis identified 20 themes and 59 sub-themes, which were refined into two overarching categories: (1) shared barriers to SDM in SAPS care, including diagnostic uncertainty, fragmented clinical care pathways, time constraints, and decision fatigue; and (2) stakeholder visions for future SDM interventions, emphasising continuity, tailored communication tools, and supportive digital ecosystems. Conclusion: Based on stakeholder input, SDM in SAPS care may consider integrating dynamic, integrated systems that account for diagnostic ambiguity, contextual constraints, and varying patient capacities. These findings provide an actionable foundation for co-developing and piloting a context specific SDM intervention for primary care.
