Pros

“Viedoc is a custom friendly eCRF development platform, where you can customize the placement of fields anywhere as per the requirement, which is not part of any other EDCs.”

Kowsalya N.

Data Manager

“Its EDC system combines precision and simplicity with drag-and-drop study design, real-time data validation, and automated compliance (FDA 21 CFR Part 11, GDPR), speeding database development.”

Janus R.

“Viedoc seamlessly integrates EDC, ePRO, and RTMS into a unified, intuitive platform, for clinical trial management.”

Janus R.

Head of Data Management

Pros

“Layout of data events, security features of eConsent (ie. two factor, audit history), and now how the data event reminders are email/SMS.”

“The interface is modern and not overly complicated.”

Corinna P.

Project Associate

“Very very great experience, Its very easy to navigate which is the best thing when you are training new people and also setting up new studies”

Anirudha L.

Sub Investigator

Cons

“There is no option to leave comment in cases of data not applicable or not collected in error.”

Ebaa H.

Study Coordinator

“Lot of features from Viedoc 3 such as monitoring reports, sae reporting are lacking in viedoc 4.”

Rajalakshmi V.

Senior Technical Specialist

“Impossible to select a query from the research field with key words, impossible to navigate between several forms when an edit check is related to more than one form.”

Venel F.

Senior Data Manager

Cons

“This created a lot of issues for us in the long run, as when you want to edit a single form at a certain timepoint, it ends up changing all the timepoints that use this same form”

Nishat H.

Research Trial Manager

“The lack of in-depth monitoring reports makes it difficult to generate detailed overview of data points.”

Joshua T.

Clinical Research Associate II

“You cannot navigate between visits without leaving page and entering participant view again.”
