settings. This summary provides an update on the benefits, barriers to use with large
clinical databases, policy frameworks that have been formulated, and challenges.
Methods: This report highlights some recent publications on the diverse uses of clinical data
and some policy initiatives to promote reuse. It also contains the opinions of the
author.
Results: Although many examples of the benefits of data reuse have been documented, this summary
also reviews why the quality of clinical data needs to be the focus of future informatics
work.
Conclusion: The promise of reusing data outweighs potential risks, but concerns about privacy
and the need to modernize our legal framework will be necessary to realize the full
benefits of real-world evidence.
