CIRCE - Cohort Inclusion and Restriction Criteria Expression
When performing an analysis, usually the first step is to define the population of interest (also known as a cohort). However, there is limited technology out there that makes it easy for a user to define populations based on user-specified criteria. CIRCE provides a user interface for users to enter cohort criteria, persist them to storage, and generate the CDM v5 SQL queries.
The scope of CIRCE is to enable a researcher to specify criteria that identifies a patient population within the Common Data Model (CDM). The criteria available for cohort definition is directly mapped to the entity types found in the CDM v5: Person, Condition_occurrence, Condition_era, Drug_Occurrence, Drug_era, Procedure_occurrence, Observation, Visit, and Death. By having a well-defined data-structure for capturing cohort definition criteria, definitions can be shared between CDM environments to do comparative analysis.
* Ensure that you have OHDSI Web API service installed in your environment. see https://github.com/OHDSI/WebAPI * CIRCE client is installed on any HTTP server.
