RESUMEN
INTRODUCTION AND HYPOTHESIS: To understand the patient burden of study procedures/measures at completion of a randomized controlled trial (RCT) requiring extensive testing and follow-up visits. METHODS: A survey sent after completing the 2-year visit of an RCT comparing Burch colposuspension and fascial retropubic sling to treat stress urinary incontinence assessed degree of bother for seven study procedures, eight study-related factors, and possible motivations to participate in the study. RESULTS: A total of 450 study participants (88%) returned the survey. Urodynamic testing was the most bothersome procedure, followed by 24-h pad test and Q-tip test. Self-administered questionnaires were the least bothersome. Main reasons to participate in the study were to help others, obtain better knowledge about the condition, and be guided by a committed team of investigators/study coordinators. CONCLUSIONS: At the end of a large multicenter RCT, we learned from a confidential patient survey that the most burdensome activities involved invasive procedures, frequent visits, and multiple forms to fill out.
