README

This is a primer to CQL, designed for beginners with FHIR and CQL.

Intent

The intent is to demonstrate the ability to:

1. create mock patient data using Synthea
2. explore patient data using the HAPI FHIR server
3. execute logic on patient data using a CQL artifact with the cql-runner

For the purpose of this primer, I've selected the simplest example of calculating the BMI of a patient.

Prerequisites

1. install Docker
2. install docker-compose

Getting started

1. build: docker-compose build
2. start: docker-compse up -d
3. you may want to follow synthea to see the progress: docker-compose logs --follow synthea
4. find the services running on:
   1. FHIR server: http://localhost:8080/
   2. cql-runner: http://localhost:8081/
5. Find a patient ID within the FHIR server
6. Copy a CQL artifact into the cql-runner (/cql-runner/artifacts/bmi.cql)
7. Configure the patient ID in the cql-runner
8. Run the artifact
