The main goal is to understand what it is truly like to live with OAB from the patient's perspective, including how it affects: daily activities, emotional wellbeing and mental health, social life and relationships, work and overall quality of life.

The REVEAL-OAB (Real-world Experiences and Voices Exploring the Actual Lived burden of Overactive Bladder) study is a large, international, mixed-methods research program designed to capture both the measurable burden and the lived experience of overactive bladder (OAB).Quantitatively, it uses structured surveys and validated patient-reported outcome measures to assess symptom severity (e.g., urgency, frequency, incontinence), health-related quality of life, healthcare utilization, and treatment patterns across diverse populations. Qualitatively, it incorporates in-depth patient interviews, open-ended survey responses, and narrative data to explore how OAB affects emotional wellbeing, social functioning, relationships, and daily decision-making. By integrating these quantitative metrics with rich qualitative insights, the study aims to provide a comprehensive, patient-centered understanding of OAB, identify unmet needs in care, and inform more effective clinical management and health policy.
