This is electronic patient-reported outcome (ePRO) data collection, and it has quietly transformed how a significant proportion of clinical trial data reaches the sponsor's database. For the coordinator, it eliminates one entire category of work -- the transcription step from source to CRF that occupied much of Modules 3 and 4 of this course. But it introduces a different category of work that is, in my experience, less intuitive and more easily neglected: training participants to use the technology, monitoring their compliance through dashboards rather than binder pages, troubleshooting devices that malfunction at 9:00 PM on a Saturday, and understanding the source documentation implications of a system where the participant -- not the coordinator -- creates the official record.

This lesson teaches the operational reality of ePRO and the broader family of electronic clinical outcome assessments (eCOA). It is grounded in the data integrity principles you learned in Module 1 and the source documentation concepts from Module 2, applied to a data collection paradigm where the coordinator's role shifts from data creator to data steward.
