Focus group study of factors relevant to treatment decisions and experiences among patients with symptomatic peripheral artery disease.

Abstract

Clinical guidelines recommend shared decision-making for treatment of peripheral artery disease (PAD), which requires understanding of patient perspectives and preferences. We conducted a focus group study of patients with symptomatic PAD to identify factors important and relevant to treatment choices, and to characterize aspects of the health care process that contribute to positive vs negative experiences apart from the specific treatment(s) received. Participants were recruited from an academic medical center over 2years using a purposeful sampling approach based on a clinical diagnosis of symptomatic PAD (either claudication or chronic limb-threatening ischemia [CLTI]) confirmed by the abnormal ankle or toe brachial index. Focus groups were led by a nonphysician moderator, consisted of 5 to 12 participants, and were conducted separately for patients with CLTI and claudication. Audio recordings converted to verbatim transcripts were used for qualitative analysis. A total of 51 patients (26 with CLTI and 25 with claudication) were enrolled and participated in focus groups. Major themes identified related to treatment preferences and decisions included specific interventions under consideration, the chance of technical success versus failure, anticipated degree of symptom improvement, outcome durability, and risk.Major themes related to the process of care included decision-making input, provider communication and trust, the timeline from diagnosis to definitive treatment, and compartmentalized care (including different venues of care). The results provide insights into patient preferences, perspectives, and experiences related to PAD treatment. These observations can be used to inform patient-centered approaches to shared decision-making, communication, and assessment of PAD treatment outcomes.
