Background: The choice of treatment is an unavoidable challenge faced in the day to day medical decision making pertaining to patients with organic heart disease. As a professional discipline, cardiac surgery focuses on creating and using the most advanced evidence-based patient decision aids (PtDAs) to achieve highquality decision-making. Objectives: To describe the basic situation, influencing factors, and the outcome of indicators of PtDAs among cardiac surgery patients. Methods: Seven electronic databases were systematically searched for relevant reviews on the application of PtDAs among cardiac surgery patients. The methodological framework proposed by Arskey and O'Malley was used to guide the scoping review. The extracted data was analyzed qualitatively and quantitatively. Results: After dual, blinded screening of titles and abstracts, 12 articles were included in the review. 10 were quantitative studies, 1 was a mixed study, 1 was a qualitative study. Conclusions: Compared with the burden of heart disease and the huge evidence base, the application of PtDAs in cardiac surgery is obviously insufficient. The published literature mainly provide information about the factors to be solved from the perspective of researchers, and also summarize obstacle factors. This is the basis for the application and construction of PtDAs in cardiac surgery patients. (c) 2022 The Authors. Published by Elsevier Inc.
