RESUMEN
BACKGROUND: In recent years, decision support tools (DSTs) in various fields of medicine have emerged to aid clinicians and patients in the process of shared decision-making (SDM). This scoping review aims to identify the existing DSTs for selecting treatments in lower extremity arterial disease and to evaluate their effectiveness in facilitating SDM. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for scoping reviews were followed. A literature search was conducted across MEDLINE, EMBASE, and Cochrane databases, along with the Decision Aid Library Inventory, for studies published between January 2000 and June 2023. Articles reporting the development and/or clinical application of a DST specific to lower extremity arterial disease were included. A narrative synthesis of the results was performed and findings were presented in tabular formats. RESULTS: Five studies and 5 unique DSTs were included. Presenting formats included websites, booklets, brochures, and pocket cards. Overall, a high degree of heterogeneity was observed across all DSTs in their format, content, and delivery. A widespread acceptability and satisfaction were reported among patients and clinicians. However, their effect at improving SDM remains uncertain due to the lack of standardized outcome metrics. CONCLUSIONS: The development and implementation of DSTs for lower limb arterial disease treatment discussion remain in the early stages. This review lays the foundation for future studies to continue exploring optimal strategies for DST development and their role in supporting SDM.
