Abstract
Background
Randomized controlled trials (RCTs) are foundational in advancing medical knowledge and patient care, offering high-quality evidence on the comparative effectiveness of healthcare interventions. However, a common challenge for RCTs is the recruitment of trial participants. To understand and overcome potential obstacles in recruitment for a clinical trial (the LightBAR trial, NCT06309238) comparing the effectiveness of bariatric surgery versus an intensive weight loss program, a qualitative study was conducted.
Methods
Nine patients from the public bariatric surgery waiting list participated in focus groups at a hospital in the Capital Region of Denmark. Vignette scenarios were utilized to prompt participants to reflect on barriers and facilitators for participation. Three patients participated in a follow-up interview. Data was analyzed using thematic analysis.
Results
Analysis revealed four main themes: (1) having waited long for surgery reduced participants’ willingness to be randomized; (2) the cost of weight loss medication was a major concern for participants; (3) participants were concerned about the extra work involved in program participation; and (4) participants weighed the efficacy and potential negative side effects of surgery against those of an intensive weight loss program based on personal beliefs and experiences.
Conclusions
Tailoring the recruitment strategy to patients’ circumstances and concerns, and providing clear, patient-centered communication about the nature and potential implications of participating in the trial may improve recruitment success.
