Announcing Source Data Verification in VISION EDC

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 give clinical trial monitors an easy way to see which fields still need to be verified.

 

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 formThis 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. 

 

The audit trail shows information about the user who performed the Source Data Verification.

 

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 responsibilitiesOccasionally, 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.

How Can the Dynamic Drop-Down Menu be Utilized in a Study?

VISION’s user-friendly tools for customizing forms includes a handy tool known as the dynamic drop-down. This deceivingly simple field packs a lot of punch. While you can leave the drop-down menu as just that, a menu and nothing more, did you know that you can also use this menu to populate other fields or even populate it from other fields?

A great place to use this tool is on the Adverse Events and Concomitant Medications forms, so that the two can communicate with each other. If a con med gets administered to a subject due to an adverse event, both need to be documented. Using a dynamic drop-down menu on each form for the relevant subject saves a great deal of time and streamlines documentation. Once it is noted on the con med form that a medication was administered after an adverse event, then a menu appears with all previously entered adverse events for that subject. Simply select the correct event, and now the medication and adverse event are linked. Vice versa, If an adverse event required the administration of a medication in a subject, then you can select from a drop-down menu on the adverse events form all previously entered con meds.

This tool opens the door to many more opportunities for customization and, therefore, simplification of data-entry. Signature drop-down menus can either be populated from another field, i.e., from a list of names, or be role-based, meaning the names of every user who has been assigned a specified role will appear as an option. The menu for the reason a subject was withdrawn can be pre-populated conditionally, e.g., only if the subject was euthanized. This would save the investigator time as there would be no need to answer a slew of unnecessary questions to close out a patient. The transcribed CRF form features a drop-down menu that can be based on all forms or form groups, or it can include or exclude specific forms or form groups. Dynamic drop-downs can even communicate between subjects and sites, e.g., when updating con med and adverse event dictionaries.
