OHDSI seeks to create a validated content library to enable reproducible research. The library touches on the activities of many working groups, including APHRODITE, CIRCE, ATLAS / HERMES, LAERTES, PENELOPE, and the PheKB definition effort. In addition to these activities, the Library has its own standalone requirements. This project page is designed to faciliate defining the requirements of the OHDSI library.

Content Types

• Phenotypes (e.g., Patients with Hyperlipidemia)
• Clinical Components (e.g., Elevated Cholesterol Values (e.g. [LDL > 130 OR Total Chol > 200])
• Concept Sets (e.g., concept codes meaning Low Density Lipoprotein (LDL))

Note that Clinical Components are not currently implemented in OHDSI so would require development effort.
