Patient-generated reports, also known as Patient-Reported Outcomes (PROs), capture the patients' illness experience in a structured format and may help bridge the gap between patients and providers. PROs measure any aspect of patient-reported health (e.g., physical, emotional or social symptoms) and can help to direct care and improve clinical outcomes. When clinicians systematically collect patient-reported data in the right place at the right time, PRO measurement can effectively aid in detection and management of conditions, improve satisfaction with care and enhance the patient-provider relationship. This review article summarizes the latest approaches to PRO measuring for clinical trials and clinical practice, with a focus on use of PROs in gastroenterology.
