Frequently Asked Questions (FAQs)

What does ePRO mean in clinical research?

ePRO (electronic Patient-Reported Outcomes) refers to digital systems that allow patients to directly report health conditions, symptoms, and treatment responses using electronic devices such as smartphones, tablets, or web-based platforms.

What are ePatient Diaries?

ePatient Diaries are digital tools used in clinical trials to record patient experiences, medication adherence, symptoms, and quality-of-life data in real time, improving data accuracy and compliance.

What is eCOA and how is it different from ePRO?

eCOA (electronic Clinical Outcome Assessment) is a broader category that includes ePRO, clinician-reported outcomes (eClinRO), observer-reported outcomes (eObsRO), and performance outcomes (ePerfO). ePRO is a subset of eCOA focused specifically on patient-reported data.
