Nuts demo EHR system

This application is pretending to be an electronic health record system. You can use it to demo how healthcare professionals can work together by sharing information with colleagues through the Nuts nodes.

It uses a FHIR server for the storage of patients, observataions and tasks. We use the Smart dev sandbox with FHIR R4 and Synthea data for a quick setup. You can generate a localized data set using the Internaltion profiles for Synthea.

This version is an updated version using vue.js as frontend framework and a Golang backend. It's based on the nuts-registry-admin-demo.

Go to the master branch to find the previous version of the app.

NOTE THAT THIS APPLICATION IS NOT INTENDED FOR USE WITH REAL MEDICAL INFORMATION! IT IS IN NO WAY DEVELOPED TO BE SAFE, STABLE OR EVEN USABLE FOR SUCH PURPOSE.

Building and running

Production

To build for demo-production:

npm install
npm run build
go run .

This will serve the front end from the embedded filesystem.

Development

During front-end development, you probably want to use the real filesystem and webpack in watch mode:

npm install
npm run watch
go run . live

The API and domain types are generated from the api/api.yaml.

npm run gen-api

oapi-codegen -generate server -package api api/api.yaml > api/generated.go
oapi-codegen -generate types -package types -o domain/types/generated_types.go api/api.yaml

Docker

docker run -p 1304:1304 nutsfoundation/nuts-demo-ehr:main

Configuration

When running in Docker without a config file mounted at /app/server.config.yaml it will use the default configuration.

Starting the HAPI FHIR server backend

The simplest way of starting up an out of the box FHIR backend is using the HAPI FHIR server by running the following docker command:

docker run -p 8080:8080 -e hapi.fhir.fhir_version=DSTU3 -e hapi.fhir.partitioning.allow_references_across_partitions=false hapiproject/hapi:v5.4.1

Configuration explanation:

  • hapi.fhir.fhir_version=DSTU3 indicates FHIR version STU3 is used
  • hapi.fhir.partitioning.allow_references_across_partitions=false signals HAPI server to enable partitioning, which allows multi-tenancy.

FHIR server type

If you're using the HAPI FHIR docker image or any other HAPI FHIR server with support for multi-tenancy you should set the fhir.server.type option to: hapi-multi-tenant otherwise choose either hapi (for a single-tenant HAPI FHIR server) or other.

Nuts-node

The Demo-EHR needs a connection to a running Nuts node. The customers.json file also needs to be in sync with the DIDs known to the Nuts node. You can use the nuts-registry-admin-demo for setting up customers.json.

It's important to configure the Nuts node address in the server.config.yaml. The nutsnodeaddr must be used for this:

nutsnodeaddr: "http://localhost:1323"

When using IRMA for authentication, the Nuts node will generate a QR code with an URL in it. This URL must be publicly accessible. It can be configured IN THE NUTS NODE configuration file:

auth:
  publicurl: http://5d6670ee3d46.eu.ngrok.io

The above example uses ngrok to proxy a ngrok URL to localhost:1323.
