Source Data Verification
Prelude Dynamics continues to enhance our VISION™ platform with crucial features requested by our clinical trial user community. The ability to perform Source Data Verification (SDV) in the context of EDC has become more and more important as we’re migrating away from paper. VISION’s SDV functionality operates at the field level and complements the existing form review capability. How does it work?
Users who have permission to review forms can activate the SDV feature simply by clicking an icon on the form. When this is done, check boxes appear next to the fields on the form.
Check boxes are automatically cleared if the reviewed field is later changed – letting monitors easily see which fields need to be re-reviewed, while preserving the reviewed state of other data entry elements on the form. This is a time-saver for monitors, and saving time saves money!
These field-level SDV reviews are fully attributed and preserved in the audit trail in a 21 CFR compliant manner.
Even though most of our clients use VISION to directly enter data as the source (eSOURCE), in some cases there might be a need for SDV. Let’s consider a few scenarios.
Transcription of data from paper forms
First consider the transcription of data from paper forms (or pictures of paper forms) such as subject/owner logs or paper patient reported outcome forms to EDC. In the past, Double Data Entry (DDE) was typically used for situations such as these. SDV is an improved replacement for DDE, especially when used along with a file upload that allows a copy of the original paper form to be uploaded directly to the EDC.
Review of Adverse Events
Monitors typically want to review Adverse Events as soon as they are entered into the EDC as part of their safety assurance responsibilities. Occasionally, investigators haven’t completed all the information in the Adverse Event eCRF because they are still conducting analysis on the possible cause. In cases such as this, Monitors can review the data that has been already entered. When they revisit the form later, they will know which information has already been reviewed. This also works well for Concomitant Medications.
