Background:
Factors influencing patients' motivations for enrolling in, and their experiences of, orthopaedic randomized controlled trials (RCTs) are not fully understood. Less is known about healthcare professionals' (HCP) experiences of RCT involvement.
Aim:
This study investigates patients' and HCPs' views and experiences of RCT participation and delivery to inform the planning of future RCTs.
Methods:
Total hip or knee replacement patients (n = 24) participating in the single-center double-blind APEX RCTs of an intra-operative anesthetic intervention and HCPs (n = 15) involved in trial delivery were interviewed. Data were audio-recorded, transcribed, anonymized and thematically analyzed.
Results:
Although altruistic reasons for RCT participation were common, patients also weighed up demands of the RCT with the potential benefits of taking part, demonstrating the complex and conditional nature of trial participation. HCPs were interested in RCT involvement as a means of contributing towards advances in medical knowledge and also considered the costs and benefits of RCT involvement.
Conclusion:
Patients and HCPs value involvement in RCTs that they see as relevant and of value, while imposing minimum burden. These findings have important implications for the design of methods to recruit patients to RCTs and for planning how an RCT might best interface with HCP clinical commitments.
