Decision aids for promoting shared decision-making: A review of systematic reviews

In the context of shared decision-making (SDM), experts have advocated the use of validated decision aids (DAs) as valuable tools for facilitating SDM in various healthcare scenarios. This comprehensive review attempts to analyze a vast corpus of DA research by performing thorough searches across four prominent databases (PubMed, CINAHL, Embase, and Web of Science). Independent reviewers selected relevant reviews, extracted data, and assessed review quality using the AMSTAR II tool. A total of 34 systematic reviews were identified and evaluated in this review, encompassing a wide range of outcomes associated with using DAs. These outcomes include patient knowledge, patient involvement in SDM, decision conflict, decision regret, satisfaction, and adherence. In addition, DAs positively affect healthcare provider outcomes by increasing satisfaction, reducing decision conflicts, and lengthening clinical consultations. This review highlights the need for additional research in specific contexts such as long-term care, mental health, and reproductive health to better understand the benefits and challenges of implementing DAs in these settings. Such research can contribute to the improvement of SDM practices and patient-centered care.
