FHIR (Fast Healthcare Interoperability Resources)

Introduction

The FHIR standard is developed specifically for Healthcare interoperability. This scenario periodically reads a record from a FHIR service and then updates the same record.

Getting Started

You can follow with the video above to build the integration or you can import the FHIRDrill-export.zip, or you can create from scratch starting with configuring a FHIR Connection. For this I'm using the following FHIR service endpoint

http://hapi.fhir.org/baseDstu3/

FHIR Connection Figure 1. Configure the FHIR Connection

The start action is a Simple Timer that fires every minute. The finish connection is a FHIR connection where we select the update action. Then we add a step in the middle to read a Patient record from the same FHIR connection. You can verify the Patent 22964 record exists by looking at

http://hapi.fhir.org/baseDstu3/Patient/22964

Finally we add a DataMapper Step to map

tns.id/tns:value -> tns.id/tns:value
tns.name/tns.family -> tns.name/tns.family
tns.name/tns.given -> tns.name/tns.given
tns.name/tns.family -> tns.name/tns.text/tns.value

and add Log Steps before and after the DataMapper, then Deploy the integration and the activity log should show activity.

What did we learn?

  • We learned how to Read and Update a record on a FHIR server.
  • We learned to navigate the complex FHIR API using JSON/XML in the DataMapper and we mapped some fields.
