Objective: To enable members of the OHDSI community to find, evaluate, and utilize community-validated cohort definitions for research and other activities. These “gold standard” definitions will reside in a library, the entries of which are held to specific standards of design and evaluation. These standards are what this working group is ultimately working to establish, as well as the instantiation of the library itself.

To achieve the above objective, we are focusing on the following Subtasks:

1. Design: Rule-Based (Heuristic) Phenotypes
2. Design: Computable (Probabilistic) Phenotypes
3. Evaluation: Manual Chart Review / Annotations
4. Evaluation: Automated / Algorithmic
5. Library Architecture and Implementation

Each subtask has a Task Leader:

1. TBD
2. Juan Banda
3. Seng Chan You
4. Joel Swerdel
5. Aaron Potvien
