What are the decision-making preferences of patients in vascular surgery? A mixed-methods study

Objectives: Shared decision-making (SDM) has been advocated as the preferred method of choosing a suitable treatment option. However, patient involvement in treatment decision-making is not yet common practice in the field of vascular surgery. The aim of this mixed-methods study was to explore patients' decision-making preferences and to investigate which facilitators and barriers patients perceive as important for the application of SDM in vascular surgery. Design and setting: Patients were invited to participate after visiting the vascular surgical outpatient clinic of an Academic Medical Center in the Netherlands. A treatment decision was made during the consultation for an abdominal aortic aneurysm or peripheral arterial occlusive disease. Patients filled in a number of questionnaires (quantitative part) and a random subgroup of patients participated in an in-depth interview (qualitative part). Results: A total of 67 patients participated in this study. 58 per cent of them (n=39) indicated that they preferred a shared role in decision-making. In more than half of the patients (55%; n=37) their preferred role was in disagreement with what they had experienced. 31 per cent of the patients (n=21) preferred a more active role in the decision-making process than they had experienced. Patients indicated a good patient-doctor relationship as an important facilitator for the application of SDM. Conclusions: The vast majority of vascular surgical patients preferred, but did not experience a shared role in the decision-making process, although the concept of SDM was insufficiently clear to some patients. This emphasises the importance of explaining the concept of SDM and implementing it in the clinical encounter.
