What Is ePRO?

Electronic patient-reported outcomes (ePRO) have become central to capturing how patients truly experience treatments during clinical trials. By collecting data directly from participants through digital tools, ePRO provides real-time insight into symptoms, side effects, daily functioning, and quality of life — without relying on site visits or paper diaries. This patient-first approach reduces recall bias, improves data completeness, and strengthens confidence in trial results.

Designed for accessibility, ePRO platforms use familiar interfaces like mobile apps or web-based questionnaires, supported by reminders that help participants stay on schedule. For study teams, electronic capture enables continuous monitoring, clearer audit trails, and faster responses to emerging trends or safety concerns. ePRO also supports decentralized and hybrid trial models, expanding participation while reducing operational burden. With thoughtful planning, training, and ongoing support, ePRO becomes a reliable foundation for collecting meaningful, patient-centered data throughout the study lifecycle.
