In all of these situations, the question becomes how to generate real-world evidence from these different data sources?

We at OHDSI are serving all of these data holders by building tools and establishing processes to help standardize and analyze data in a higher quality and more efficient way.

If you are a data holder and are interested in collaborative research — and would like to participate in establishing and applying scientific best practices in your research — you are invited to join the OHDSI collaborative and conduct analyses on your own data or across the OHDSI data network.
