omopfhirmap for mapping FHIR <--> OHDSI OMOP CDM

About

Omopfhirmap is a command-line tool for mapping a OHDSI cohort, defined in ATLAS, to a FHIR bundle that can be optionally submitted to a FHIR server for processing. Conversely, it can process a FHIR bundle and add resources to an existing CDM database ignoring duplicates. Unlike GT-FHIR2, the OMOP on FHIR Project at Georgia Tech omopfhirmap does not expose OMOP database as FHIR endpoints.

javadoc

Use cases

• To export a cohort to a FHIR based analytics tool.
• To load new resources to OMOP CDM databases for incremental ETL.

Build

mvn clean install spring-boot:repackage

Usage

java -jar <omopfhirmap.jar> <function> <source> <destination> --spring.config.location=<properties file>

Examples

• java -jar target/omopfhirmap-0.0.1.jar help

• java -jar target/omopfhirmap-0.0.1.jar tofhirbundle 2 test-fhir.json --spring.config.location=application.properties This will convert the cohort defined in Atlas with an ID of 2 (looks in the cohort table in results schema) and writes the FHIR (collection) bundle.

• java -jar target/omopfhirmap-0.0.1.jar toomop test-fhir.json 3 --spring.config.location=application.properties Imports the FHIR bundle in the above file, creates persons, observations, measurements, procedure and visit occurences. Finally it creates a new cohort with ID 3 (Can be seen in Atlas)

• Sample application.properties

spring.main.banner-mode=off

logging.level.root=ERROR
logging.level.org.foo.bar.baz=INFO

Work in progress

• I have only mapped FHIR.Patient <-> OMOP.Person so far.
• PRs welcome if you want to map others.
• Please star the repo, if you find this useful and want to see other mappings completed.

Design

• JAVA >= 13
• FHIR R4
• Multi-Threaded
• Uses spring-boot and JPA for wiring of services and abstraction of database.
• Can easily add support for other databases using spring-boot

Other projects

• Check out csv-fhir-mapper
• Python package for OMOP CDM
• .Net library for OMOP CDM
• Go library for OMOP CDM
