FHIR Server Implementation Track

Objective

The objective of FHIR Implementation track is to provide a starting point for participants to put their FHIR knowledge into practice.

The track covers the basics of Facade & Repository FHIR Server implementation.

Outcome 

After participating in this track, participants would be able to 

• Implement a basic
  • HAPI FHIR Facade Server
  • HAPI FHIR JPA Server
• Be aware of Extraction -> Ingestion -> Retrieval steps within an application workflow.
• Become familiar with:
  • FHIR Resource Extensions
  • Custom types in FHIR resources
  • FHIR interface Interceptors
  • Security configurations of HAPI FHIR server

Upon completion of this track, participants would be able to work on real-life use cases such as Ayushman Bharath Digital Health Mission https://ndhm.gov.in/. 

Intended Audience

• Solution Architect
• Product Owner
• Developers
• Participants of FHIR Starter Tracks from previous Connectathon
• Students (Health Informatics)

• Basic knowledge of “Java Spring Boot” for creating new project\executing application.
• Basic knowledge of Spring Data JPA.
• Basic knowledge of MAVEN for adding different dependencies in pom file

Track Orientation

Following topics are covered in "Orientation Sessions" conducted as part of Pre-Connectathon. It is highly recommended that participants to engage early with track to get the best benefits. 

* Important & Mandatory

Infrastructure Provided

Use cases

Facade/Plain Server Approach:

The HAPI FHIR Plain Server often referred to as a Facade, is an implementation of a FHIR server against an arbitrary backend. During Connectathon, we shall use the database of OpenEMR. This use case will cover: 

• Search, Create, Read operations for Patient Resource
• Search, Create, Read operations for Observation Resource using simple Laboratory Results. 

Repository Server Approach:

The HAPI FHIR JPA Server is a complete implementation of a FHIR server against a relational database. Unlike the Plain Server, the JPA server provides its own database schema and handles all storage and retrieval logic without any coding being required. The JPA server has been successfully used in many use cases. This use case will be cover: 

• Input EMR data (Patients & Observation) in V2 HL7 messages from text file
• Design and Mapping of Patient and Observation FHIR resource
• Load data into FHIR server using FHIR server provided APIs
• Read the EMR data using APIs provided by FHIR server
