A tool for generating clinical notes using Synthea patient FHIR Bundles.

This project contains the chatty.py script that will take a FHIR Bundle as input. It then scans the FHIR Bundle for encounters. Given information on the encounter, pulled from other resources in the bundle, it will create a prompt for ChatGPT. The script uses OpenAI Chat completions API to supply the prompt and get a response.

git clone https://github.com/synthetichealth/chatty-notes.git
cd chatty-notes/
pip install -r requirements.txt

Running the script requires setting up an account with OpenAI and getting an API key. The API key should be added to the environment in the OPENAI_API_KEY variable.

export OPENAI_API_KEY=YOUR_KEY_HERE
python chatty.py -b PATH_TO_FHIR_BUNDLE

The new bundle will be written to an output directory. The bundle file will have the same base name as the input file. An output directory will be created if one doesn't already exist.

This is how it can be done using GNU Parallel:

ls ../synthea/output/fhir/*.json | awk '!/Information/' | parallel python chatty.py -b {}

This will process all bundle files in the directory in... parallel.

In this case, awk is used to remove the hospital and provider information files from the pipeline.
