- \n
- Breaks healthcare data into small, modular components called resources (e.g Patient, Encounter)<\/li>\n
- Defines standard structure, content, and semantics for these.<\/li>\n
- Exposes healthcare resources via RESTful APIs.<\/li>\n<\/ul>\n
Example of simple Patient resource:<\/p>\n
{\r\n \u00a0\"resourceType\": \"Patient\",\r\n \u00a0\"id\": \"example\",\r\n \u00a0\"name\": [{\"family\": \"Sheikh\", \"given\": [\"Mavin\"]}],\r\n \u00a0\"gender\": \"male\",\r\n \u00a0\"birthDate\": \"1980-26-26\"\r\n}<\/pre>\nWhat is SMART on FHIR?<\/h2>\n
SMART on FHIR is an open standard that allows third-party apps to connect with healthcare systems using FHIR Rest API\u2019s and standardised OAuth 2.0 authorization flows.<\/p>\n
SMART App Launch Types<\/h2>\n
SMART on FHIR defines three ways to launch the app:<\/p>\n
- \n
- Standalone Launch<\/strong>: Launched directly by the user outside the EHR.<\/li>\n
- EHR (also called as Embedded) Launch<\/strong>: Launched within an EHR application.<\/li>\n
- Backend systems<\/strong>: For Apps without direct end user or patient interaction (In this blog we will only discuss first two launch types)<\/em><\/li>\n<\/ul>\n
Standalone Launch Sequence<\/h2>\n
- \n
- Register the App with the FHIR server to get a Client ID (e.g, via Epic<\/a> or Cerner<\/a>).<\/li>\n
- The user visits your app directly outside of EHR.<\/li>\n
- Get SMART well known configuration from the FHIR server (also called as conformance statement).<\/li>\n
- Redirect user to the FHIR server\u2019s authorize endpoint.<\/li>\n
- FHIR server authenticates user and redirects to your callback url with an authorization code.<\/li>\n
- Exchange the code at the token endpoint to get access token.<\/li>\n<\/ul>\n

<\/p>\nStandalone launch sequence<\/p>\n<\/div>\n
<\/h1>\n
EHR (Embedded) Launch Sequence<\/h2>\n
EHR (Embedded) Launch Sequence is same as standalone, except<\/strong>:<\/p>\n
- \n
- App is launched from within the EHR.<\/li>\n
- EHR passes a launch context and iss<\/strong> (FHIR base URL).<\/li>\n<\/ul>\n\n

Step-by-Step Implementation<\/h2>\n
Step 1: Register Your App<\/h3>\n
Register your app with the desired FHIR platform (Epic, Cerner etc) to get client credentials and configure redirect URI.<\/p>\n
Step 2: Setup Express App (app.ts)<\/h3>\n

Testing Your Application<\/h2>\n
Standalone Launch<\/h3>\n
Start your server: npm run start<\/strong> and try:
\nEpic: http:\/\/localhost:3000\/auth\/standalone\/epic<\/a><\/em>
\nCerner: http:\/\/localhost:3000\/auth\/standalone\/cerner<\/a><\/em><\/p>\nYou will be redirected to the EHR login screen. After successfully logging in, you will receive access token.<\/p>\n
Embedded Launch<\/h3>\n
To simulate embedded launch use the SMART App Launcher with your embedded endpoint: http:\/\/localhost:3000\/auth\/embedded<\/p>\n
Using token to access FHIR resources<\/h2>\n
Once you receive valid access token, your can now access protected patient data from the EHR database using FHIR Rest APIs. You need to pass access token in authorization header as a Bearer token.<\/p>\n
GET <fhir-server-url>\/Patient\/{id}\r\nAuthorization: Bearer Nxfve4q3H9TKs5F5vf6kRYAZqz...<\/pre>\n<\/h1>\n
Adding Support for a New EHR<\/h2>\n
Adding support for another SMART on FHIR compliant EHR is simple, <\/strong>Just add another provider entry in ehrAuthConfig<\/strong> inside config.ts. No additional logic required!<\/em><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
Introduction In the rapidly evolving landscape of health-tech, interoperability and security are critical. SMART on FHIR (Substitutable Medical Applications, Reusable Technologies on Fast Healthcare Interoperability Resources) has emerged as a robust standard to create apps that integrate seamlessly with Electronic Health Record systems.
