The Implementation of Shared Decision-Making Using Patient Decision Aid Tools to Select Breast Cancer Treatment...

Background: Research on shared decision making (SDM) has significantly increased in the 21st century. This study aims to review publications that include patient decision aid (PtDA) tools for selecting medical treatments for breast cancer (BC) since the advent of the minimum International Patient Decision Aid Standards (IPDAS) quality criteria. Methods: A systematic review was conducted using the PRISMA statement and focused on the literature published between 2013 and 2024. The databases included PubMed, Google Scholar, and PsycINFO. The quality of the studies was critically assessed. Results: A total of 29 empirical studies were examined, involving research conducted in Europe, America, and Asia. Most of the studies were quantitative clinical experiments, although qualitative and mixed methods were also reviewed. Three key themes were extracted: (1) study characteristics, including countries, sample sizes, and methodologies; (2) the clinical characterises and outcomes of the SDM processes and the implementation of PtDA tools; and (3) the various versions of the IPDAS criteria utilised. Conclusions: The medical option currently proposed includes a range of treatments, both surgical and nonsurgical options. Evidence shows positive outcomes associated with this healthcare approach; however, only half of the studies assessed utilised tools that met IPDAS criteria. Challenges remain in integrating SDM and PtDA tools into routine clinical practice, yet risk factors and potential solutions have been identified.
