PopMedNet+i2B2+and+hQuery+POC

This wiki page facilitates the Query Health proof of concept based on PopMedNet, i2B2 and hQuery.

Concept:
The proof of concept is based on existing distributed query implementations PopMedNet, hQuery and i2B2. The PopMedNet Portal and client is used to provide the transport mechanisms based on web services to transport different types of query / results. The queries are created using i2B2 and hQuery and delivered to PopMedNet which delivers the queries to corresponding handlers present in the responding organizations. For queries created by hQuery the handler would be he hQuery Gateway and for i2B2 based queries the i2B2 CRC will be handling the query execution and result formation.

This is shown in the diagram below:



Scope:
The scope of the proof of concept would be tease out the standards and services based on running code using the above pilot as a strawman. The Query Health technical workgroup sees the standards in 3 layers:
 * Layer 1: These standards and services would focus on the ability to deliver generic queries and results between Information Requestors and Responders. This layer focuses on the envelope standards and requirements.
 * Layer 2: These standards and services deal with the query and result expression along with a clinical information model. For example a standard would be to use SQL queries against a clinical information model implemented as a STAR Schema or a JavaScript based query using JSON objects. The objective of the technical work group would be to pick one base standard ultimately for query and result expression and implement the clinical information model.
 * Layer 3: These services deal with integration of existing healthcare standards such as HQMF, QRDA, C32, CCR with the Layer 1 and Layer 2 standards above.
