We propose to enhance the Open Concept Lab (OCL) suite of tools to serve as an authoritative, FHIR-compliant source for codes, value sets, disaggregates, and other metadata required to support the FHIR/mADX approach to aggregate data exchange. OCL is actively supporting a proof of concept for aggregate data exchange using the TX_PVLS indicator and would use this award to build out FHIR terminology services functionality, publish all metadata needed by the point of service, health information exchange and data warehouse layers, and to develop a thin-client web interface for browsing and searching this metadata.
This award would be used for the following: 1. Build a FHIR terminology services layer onto the existing OCL terminology server, specifically the FHIR CodeSystem and ValueSet resources. * OCL would provide FHIR-based code/code system lookups, validations, and value set expansions that would be used by the CQL execution engine in the HIE layer. * Optionally, OCL would provide point of service systems, such as OpenMRS, with access to the metadata needed to capture data in a format compatible with the aggregate data exchange process and to prepare FHIR messages. * Along with a FHIR Measure, OCL would have all the metadata required to set up a data warehouse or aggregate reporting system, such as DHIS2, to store the results of a FHIR Measure Report. 2. Model and publish definitions for all codes, value sets, disaggregates, and other metadata required to support the aggregate data exchange process. * The model to represent these definitions in OCL was already implemented for the TX_PVLS proof of concept with PEPFAR. * Optionally, store links to FHIR Measure resources in the definitions of the corresponding measures published in OCL, so that client systems may easily access the full package of metadata needed to evaluate a measure regardless of which service they access first. 3. Enhance the OCL Metadata Browser Prototype to support intuitive browsing, searching and downloading of all metadata published to OCL as part of this project and easy access to view or download the associated FHIR resources. * The OCL Metadata Browser (currently in development) is designed to be the primary method for browsing, searching, and visualizing metadata published in OCL. It is an open-source, ReactJS tool that can be used in the cloud or customized for a local implementation. It would be enhanced for this project to provide intuitive, hierarchical navigation of indicator metadata. 4. Demonstrate OCL terminology service facilitating the aggregate data exchange workflow with a selected point of service system. * We will be able to demonstrate the full workflow with a selected point of service system assuming that compatible HIE and Data Warehouse components are available. Additional information to be added soon.
