Abstract
BACKGROUND: Shared medical decision making requires patients' understanding of their disease and its treatment options. Peripheral artery disease (PAD) is a condition for which preference-sensitive treatments are available, but for which little is known about patients' knowledge and treatment preferences as it relates to specific treatment goals. METHODS: In a prospective, multicenter registry that involved patients with PAD experiencing claudication, the PORTRAIT Knowledge and Preferences Survey was administered at 1 year. It asks questions about PAD treatment choices, symptom relief options, disease management, and secondary prevention. PAD treatment preferences were also queried, and patients ranked 10 PAD treatment goals (1-10 Likert scale; 10 being most important). RESULTS: Among 281 participants completing the survey (44.8% women, mean age 69.6 ± 9.0 years), 54.1% knew that there was more than one way to treat PAD symptoms and 47.1% were offered more than one treatment option. Most (82.4%) acknowledged that they had to manage their PAD for the rest of their life. 'Avoid loss of toes or legs,' 'decreased risk of heart attack/stroke,' 'long-lasting treatment benefit,' 'living longer,' 'improved quality of life,' and 'doing what the doctor thinks I should do' had mean ratings > 9.0 (SD ranging between 1.21 and 2.00). More variability occurred for 'avoiding surgery.' 'cost of treatment,' 'timeline of pain relief,' and 'return to work' (SD ranging between 2.76 and 3.58). The single most important treatment goal was 'improving quality of life' (31.3%). CONCLUSIONS: .
