What is the difference between CTMS and EDC systems?
CTMS or Clinical Data Management System is software for managing the whole clinical trial process. EDC or Electronic Data Capture is just one of the steps in that process – creating protocols and case report forms, recording patient data, and sending it to where it belongs.
Not all clinical trials use complicated CTMSs, but most of them have an EDC, because they replace paper forms and reports. Sometimes patients use them too, when they’re accessing ePROs to report their health. We have a whole article on clinical trial software, where we explain all these systems and how they comprise the trial workflow.
