ABSTRACT
Background:
Biomedical data warehouses have become an essential tool to facilitate the reuse of health data for both research and decisional applications. Beyond technical issues, the implementation of biomedical data warehouses (BDW) requires a strong institutional data governance and the operational translation of the legal framework for the management of research data access and use.
Objective:
In this paper we describe the process of implementation and contents of a university hospital BDW.
Methods:
We present actions and challenges regarding organizational changes, technical architecture and shared governance that took place to develop the Nantes BDW. We describe the process to access to clinical contents and examples.
Results:
More than 68 millions of textual documents and 543 millions of coded information, concerning about 1.5 million of patients admitted in the clinical services of Nantes University hospital between 2002 and 2021, can be queried and transformed to be made available to investigators. Since its creation in 2018, 166 projects exploited the Nantes BDW. Access to data is organized according to data usages. We provide three examples encompassing the wealth of applications.
Conclusions:
Data usage is defined by scientific question legitimating the access to data. Implementing the access to BDW is a game changer for research and all operational situations in need of data. Finally, data governance must prevail over technical issues in institution data strategy towards care professionals and patients alike.
