hl7-hapi-fhir-obs-api

Overview

The HL7 Application Programming Interface (HAPI) Fast Healthcare Interoperability Resources (FHIR) is an open-source implementation of the HL7 FHIR standard designed for healthcare interoperability, providing a robust toolkit for developers to create applications that facilitate the exchange of healthcare data.

• This application uses Observation data (BMI) to decide if patients are classed as Obese (where BMI >= 30%).
• There are several end-points to improve familiarity with the models / Canonicals available for integration and analysis.
• This tool may help in requirements gathering and integration design for devs or teams in the Healthcare space.
• See samples of data returned by this micro service here.
