Commissioned project results

03 Sep 2013 — Gert van Valkenhoef

The Escher commissioned project, "industry requirements and a data standard for ADDIS", has been completed and the results are available.

Hans van Leeuwen carried out interviews with industry stakeholders to evaluate ADDIS as a tool for benefit-risk analysis. An executive summary of the results is now available.

Jozef Aerts evaluated the ADDIS data model and improved various aspects of it to increase compatibility with existing industry standards (CDISC, BRIDG, etc.) and internal consistency of the data model. The resulting XML Schema, validation rules, and documentation are available for download: ADDIS - Standard for Exchange of Aggregated Data in Clinical Research - Specification Document version 1.0.
