Objective To develop a patient decision aid (PtDA) for choice of surgical management for aortic dissection and to improve decision quality in patients and their families.Methods A PtDA for choice of surgical management for aortic dissection was deve-loped through literature review, expert consultation, and user adaptation. Patients with aortic dissection admitted to the department of cardiovascular surgery in August to October, 2022, were assigned to two groups according to the ward where the patient was hospitalized, with 35 in each group.The control group was given routine health education and preoperative conversation, while the intervention group additionally received PtDA for education.Decisional conflict, decision preparation, and satisfaction were compared between the two groups before discharge.Results The PtDA included 4 primary indicators, 9 secondary indicators and 31 tertiary indicators. The score of decisional conflict was significantly lower, whereas the scores of decision preparation and satisfaction were significantly higher in the intervention group compared with the control group （all P＜0.05）.Conclusion PtDA for choice of surgical management for aortic dissection is scientific and practical, which can be used to ameliorate decisional conflict and improve decision quality, resulting in achieving shared decision-making between patients and healthcare providers.
