Technical Overview
The API solution establishes a uniform interface for all BPCS services and facilitates integration through RESTful exchange. It is designed to be a distributed system that consists of a set of microservices supported by the existing HNS infrastructure, including HP NonStop and IBM Websphere Application Server. Each microservice represents a containerized application that operates on a container orchestration platform, enabling horizontal scaling.
This guide is based on the HL7 FHIR R5 standard. Implementers who do not already have a background in FHIR are encouraged to familiarize themselves with the following pages:
Level 1 Basic framework on which the specification is built:
- Foundation, including extensions
Level 2 Supporting implementation and binding to external specifications:
- Exchange, including RESTful API and Extended Operations on the RESTful API
Level 3 Linking to real-world concepts in the healthcare system:
- Administration, specifically Patient Registers
Level 4 Record-keeping and Data Exchange for the healthcare process
- Financial, specifically Billing and Other
- Medication, specifically Medications
- Security and Privacy
Specific implementation considerations around the use of FHIR include:
- Only those search parameters listed are supported. Any others specified will be ignored
- There is no support for paging. Operations returning multiple resources will return the complete set
- When specifying parameters on the URL, order of parameters is irrelevant
