A prospective community engagement initiative to improve clinical research participation in patients with peripheral artery disease

Objective: Patients diagnosed with peripheral artery disease are difficult to recruit into clinical trials. However, there is currently no high-quality, patient-centered information explaining why peripheral artery disease patients choose to participate or not participate in clinical research studies. Methods: The current study was a prospective community engagement initiative that specifically asked patients with and without peripheral artery disease: (1) what motivates them to participate in clinical research studies, (2) their willingness to participate in different research procedures, (3) the barriers to participation, (4) preferences about study design, and (5) demographic and disease-related factors influencing participation. Data were gathered through focus groups ( n = 19, participants aged 55–79 years) and mailed questionnaires ( n = 438, respondents aged 18–85 years). Results: More than half of the respondents stated that they would be willing to participate in a study during evening or weekend time slots. Peripheral artery disease patients ( n = 45) were more willing than those without peripheral artery disease ( n = 360) to participate in drug infusion studies (48% versus 18%, p
