This project configures a Node.js server to be used for testing alcohol screening and brief intervention (ASBI) clinical decision support (CDS). It leverages the Asymmetrick implementation of the Health Level 7 (HL7®) Fast Healthcare Interoperability Resources (FHIR®) specification.
This project is not intended to provide a fully-implemented and secure FHIR server. It has been configured to expose synthetic patient data over a SMART on FHIR® connection to either the ASBI CDS Screening App or the ASBI CDS Intervention App for the purposes of localhost testing. It should not be used in a production system nor should it be used to store or transmit protected health information (PHI) or personally identifiable information (PII).
This project currently only supports the EHR SMART on FHIR® launch sequence.
This project consists of several components.
Asymmetrik's node-fhir-server-core provides a FHIR® API that has been configured to provide the following resources:
- Patient
- Condition
- Observation
- Procedure
- QuestionnaireResponse
Additional resources will be exposed as needed to support ASBI CDS testing.
The express-oauth-server provides an OAuth2 endpoint required for the SMART on FHIR® connection between the FHIR® API and the ASBI CDS Screening App.
- Password authentication has been disabled since this is meant for insecure
localhosttesting only. - Issues such as the following are mitigated by the fact that
asbi-testing-serveris not meant to be used in production.
A flat JSON file is being used as the database from which the FHIR API pulls data.
Running yarn in the root directory should install all dependencies (see https://yarnpkg.com/).
Running this project assumes you have also installed the ASBI CDS Screening App:
yarn startin the root of this project- Go to where you have setup the ASBI CDS Screening App and run
yarn serve - Open a web browser and navigate to http://localhost:8080/selector.html
- Select a synthetic patient from the list
This will start the SMART on FHIR® launch sequence, which if everything is working should result in the ASBI CDS Screening App being displayed. A series of FHIR® queries will be made from the App to this project, which will respond with the appropriate resources.
