Step 4: Write your first FHIR client

In this step, the goal is to write your first FHIR client. This is a software tool that allows you to interact with an FHIR server. And also perform CRUD (Create, Read, Update, Delete) operations on FHIR resources. 

To write your first FHIR client, you will need to have some basic programming skills. Also, knowledge of a programming language such as JavaScript or Python. You will also need to have an FHIR server to connect to. 

The first step is to choose a programming language and an FHIR client library that is compatible with that language. Some popular FHIR client libraries include fhir.js, fhirclient.js, and the HAPI FHIR client for Java. 

Once you have chosen your FHIR client library, you can start writing code to interact with the FHIR server. This typically involves sending HTTP requests to the FHIR server using the FHIR API. And parsing the responses to retrieve or modify FHIR resources. 

For example, if you wanted to retrieve a patient resource. As in from the FHIR server using the fhir.js library in JavaScript, you could write code like this:

  javascript 
var fhir = require('fhir.js'); 
 
var client = fhir({ 
  baseUrl: 'myfhirserverdotcom', 
  auth: { 
    bearer: 'myaccesstoken' 
  } 
}); 
 
client 
  .read({ 
    type: 'Patient', 
    id: '12345' 
  }) 
  .then(function(patient) { 
    console.log(patient); 
  }); 

In this code, we are using the fhir.js library to create an FHIR client. It connects to an FHIR server at the URL ‘myfhirserverdotcom’, and authenticates using an access token. We then use the read method to retrieve a Patient resource with the ID ‘12345’. Finally, log in to the console. 

For non-technical people looking to implement FHIR

It may be helpful to work with a developer partner to write the first FHIR client. A healthcare software development partner can provide guidance on which programming language and FHIR client library to use. And also helps with the code-writing process.

It involves choosing a programming language and FHIR client library and writing code to interact with the FHIR server using the FHIR API. Working with a developer partner can be helpful for non-technical people looking to implement FHIR. 

Step 5: Start integrating with other systems

In this step, the goal is to start integrating with other systems. This involves using the FHIR standard to exchange health data between different systems in a consistent and interoperable way. 

Integrating with other systems typically involves using FHIR’s RESTful API to send and receive data, and mapping the data to and from the internal data formats used by each system. 

For example, a healthcare organization might use FHIR to exchange patient data between its electronic health record (EHR) system and a population health management system. The EHR system might use its own internal data model. This is to represent patient data, while the population health management system might use a different data model. By using FHIR to exchange data, the two systems can communicate with each other even though they use different data models. 

Other examples of systems that might be with FHIR integration include health information exchanges, patient portals, telehealth platforms, and mobile health apps. 

For non-technical people looking to implement FHIR

It may be helpful to work with a healthcare integration service provider to integrate with other systems. They can provide guidance on which systems to integrate with and can help with the integration process.
