EHR to FHIR System API - Implementation Template

Underlying all IT architectures are core systems of records that are often not readily available due to their complexity and connectivity concerns. System APIs provide a means of hiding that complexity from the user while exposing data and providing downstream insulation from any interface changes or rationalization of those systems. This API provides an implementation best practice to expose EHR data from systems like Epic via a set of RESTful FHIR services in RAML 1.0, making it easy to consume within an enterprise.

Healthcare Accelerator

This EHR Implementation is one of many components included in Accelerator for Healthcare. This API provides organizations with connectivity assets that accelerate project delivery in healthcare, including pre-built API designs and implementations that support core healthcare business processes.

Use Case

As a user of Healthcare API Led Connectivity Web Portal I want a microservice to act as a system API to provide services to upper layers of the architecture. This include creation, modification, and retrieval of medical data from an EHR system.

EHR System API is part of the Healthcare Templates Solution and uses the standardized FHIR structures version 3.0.1 STU3.

The API is defined using RAML 1.0 to provide type information for validation of requests and to help with the data transformation during development by providing useful metadata.

The following FHIR objects and operations are implemented in this API:

• AllergyIntolerance - search, update, create
• Appointment - search, create
• Condition - search, update, create
• Patient - search, read, update, create
• Practitioner - search, read, update, create
• Schedule - search, create
• Slot - search, read, update, create

Considerations

To run this template, there are certain preconditions that must be considered. Failing to do so can lead to unexpected behavior of the template.

This template uses SOAP services defined by WSDL files located in the src/main/resources/wsdl folder.
