Establishing development strategies and improvement paths for decision coach competencies in shared decision-making using an integrated accessibility–performance analysis and network relation map approach

A decision coach (DC) is a trained healthcare professional who provides non-directive support to patients in health-related decision-making. The decision coach role can be integrated into shared decision-making (SDM) processes, but is not an inherent component of SDM, as both may be applied independently depending on the clinical context. Numerous trained DCs are nurses who have transitioned from their roles as patient educators to knowledgeable, skilled decision facilitators. Thus, developing core competencies has become increasingly crucial for DC training, especially patient-centered care in nursing education. This study aimed to evaluate DC competencies in SDM by examining accessibility, performance, and perceived directional relationships among competency domains. This mixed-methods study combined a narrative literature review and expert consultations to identify key DC competency criteria. Subsequently, a cross-sectional questionnaire survey was administered to healthcare professionals at two hospitals in Taiwan between April 2023 and February 2024. Accessibility–performance analysis (APA) and the decision-making trial and evaluation laboratory (DEMATEL)-based network relation map (NRM) approach were applied to evaluate competency accessibility, performance, and perceived directional relationships across domains. A total of 149 healthcare professionals, including physicians, nurses, and other clinical staff, completed the valid questionnaires. The reliability of the overall criteria was measured at 0.965. The findings suggest that the professional knowledge (PK) aspect demonstrated perceived directional associations with the outcome evaluation (OE), process management (PM), and guidance skills (GS) aspects within the network structure, whereas the GS aspect was more likely to be associated with other competency domains. Each of the four aspects has a criterion critical to improving DCs’ competencies: value (PK1), listening skill (GS2), shared decision-making resources (PM3), and practical decision-making results (OE3). From healthcare professionals’ perspectives, professional knowledge was the competency domain most closely associated with perceived directional relationships among other competency aspects within the network structure. The integrated APA-NRM approach delivers evidence-based prioritization and practical pathways for developing DC competencies and guiding training strategies. Not applicable.
