Overview

We have an accelerator called Apigee HealthAPIx software solution which assists healthcare providers in accelerating the development and delivery of digital services based on FHIR (Fast Healthcare Interoperability Resources) APIs.

Apigee HealthAPIx is built on the Apigee Edge API management platform, and features FHIR APIs and a healthcare developer portal to help hospitals meet the demand for data interoperability, deliver patient-centric healthcare, and move faster to the digital world.

http://fhirtest.uhn.ca/ is a publicly accessible FHIR server We are using the DSTU2 FHIR server for this demo - http://fhirtest.uhn.ca/baseDstu2. It is accessible using the HAPI client implementation.

We have interfaced some of these APIs(appointment booking) using dialogflow.

Components

Dialog flow agent -

These are modules which convert user requests to actionable data

Apigee Edge -

  • apiai-connector - webhook for the dialog flow agent. This is where all the actionable data is used to form an RESTful request for the provider.
  • fhir-api - This is a part of the flame solution which is built as an accelerator. This is the northbound part of the proxy to which the calls are made by the apiai-connector.
  • fhir-connector - This is also part of the flame solution. This is the southbound part of the proxy which connects to the publically accessible FHIR server.
  • auth-b2b - This is also a part of the flame solution. This is a Business2business authorization module for the FHIR APIs exposed as a part of the flame solution.
