Decisional Conflict In Peripheral Arterial Disease: Association With Treatment Choice And Health Status In The Portrait Registry

Introduction: Engaging patients in medical decision-making is important, especially for conditions such as peripheral arterial disease (PAD) that have multiple treatment options. Lack of information or support in decision-making can create uncertainty about benefits and risks, and impact decisional quality. Significant work is needed to document decisional quality in PAD populations. Methods: In PORTRAIT, a multi-center study of patients with new or worsening of PAD symptoms in the US, the Netherlands, and Australia, patients were interviewed about their PAD-specific health status (PAQ - Peripheral Artery Questionnaire) and clinical variables were abstracted from medical records. The initial treatment strategy and patient-reported decisional conflict, captured using the 4-item SURE instrument, were assessed at 3 months. Patients experience conflict when they lack knowledge on treatments, treatment risks and benefits, and in the absence of support during or after the treatment decision. Variation in decisi...
