View operation history of CRF version
A CRF stands for case report form, a document used in clinical trials to collect and record study data. As the trial evolves, new insights or challenges may emerge, requiring changes to the CRF. These modifications, especially after data collection has commenced in the EDC system, lead to what is known as versioning. This process involves adapting the CRF to new protocol requirements or data collection processes during the clinical trial.
When maintaining CRF versions, you can access a detailed history of all operations carried out on a specific version. The comprehensive recording encompasses not just the actions performed on the CRF version but also chronicles its journey through various stages, including submission, progression through lifecycles, and publication to EDC.
