Announcing FHIR R5 Support

Today, we're excited to announce full support for FHIR R5, the latest version of the HL7 FHIR standard. This release brings significant improvements to healthcare data interoperability and opens up new possibilities for developers building modern health applications.

What's New in FHIR R5

FHIR R5 introduces several key improvements over R4:

  • **Improved Subscription Framework**: The new subscription model provides more flexible and powerful real-time notifications
  • **Enhanced Clinical Resources**: Updated resources for better representation of clinical workflows
  • **Better International Support**: Improved localization and international terminology bindings
  • How to Get Started

    If you're already using our FHIR R4 API, migrating to R5 is straightforward. We've maintained backward compatibility where possible and provide detailed migration guides for breaking changes.

    import { Pharmako } from '@pharmako/sdk';

    const client = new Pharmako({

    apiKey: process.env.PHARMAKO_API_KEY,

    fhirVersion: 'R5' // Now supported!

    });

    const patient = await client.fhir.patient.read('patient-123');

    What's Next

    We're committed to supporting the latest healthcare standards. Stay tuned for upcoming features including SMART on FHIR 2.0 support and enhanced CDS Hooks integration.
