SSC Launches Common Data Elements Task Force for Research Studies Related to Venous Thromboembolism

The Scientific and Standardization Committee (SSC) of the International Society on Thrombosis and Haemostasis (ISTH) has formed a task force to collaboratively define, document, publish and promote common data elements (CDE) for clinical research studies related to venous thromboembolism. The CDE Task Force consists of seven working groups charged with establishing a universal vocabulary for clinical research that will facilitate the standardized exchange of data across systems.

The project is chaired by Gregoire Le Gal (Canada), M.D., Ph.D., Professor in the Division of Hematology at the University of Ottawa and Senior Scientist in the Ottawa Hospital Research Institute. The seven working groups are as follows:

  1. General Core Data Elements
  2. Anticoagulation and Other Treatments
  3. Predictors of VTE
  4. Diagnosis of VTE
  5. Other VTE-Related Outcomes
  6. Perioperative
  7. Malignancy

Currently, the definition and coding of variables collected in these fields of study are often heterogeneous. This could lead to misinterpretation and to difficulties in synthesizing available evidence. As such, these CDE working groups will establish a consistent, interoperable and universal vocabulary for clinical research. This would allow consistent, accurate and reproducible capture of clinical concepts and research elements.

The first phase of the project will be developing a core set of common, general data elements for VTE study.  As part of the process, a draft set of CDEs will be circulated during an open comment period.  The finalized core data set will be published for those interested in clinical research and integrated into the ISTH REDCap registry platform.

The CDE task force is represented by leading experts in the SSC and is collaborating with Breakthrough Strategy, a consulting firm that works with medical societies on registry and data-set design.

“BTS is thrilled to work with ISTH on this important project to develop consistent VTE research standards,” said Sam Walters, BTS Founder and President. “Consensus-based datasets are key to powering collaborative research that will increase the power and magnitude of future research projects across the world.”

The project aims to be completed by November 2019 with a goal of sharing the finalized datasets in a corresponding journal publication. For questions or comments, please email
