Description

The ACT-NOW specification describes the data collection for oncology treatment in New Zealand, particularly medication administration.

This Guide describes how this data could be represented as FHIR resources, and collected from care delivery systems into a FHIR server for subsequent use such as Analytics and Care delivery.

As such it describes an actual implementation based around a generic FHIR server, rather than a definition of how interoperability works between systems in a particular domain. It is accompanied by a Reference Implementation - an example solution intended to validate the design and make the design more approachable to system implementers.

Details of the server requirements are found in the CapabilityStatement - though note that there are some details - like the requirement for transaction updates using conditional update - that are not reflected here.

It is intended that the guide will help inform the choice of architectural components needed for a production grade deployment, as well as the requirements for vendors supplying data to the system.

Tabs in the guide

There are a number of sections to the Guide, represented as tabs at the top of the guide.

• The Resource graph section describes how the clinical information is represented as a graph of FHIR resources
• The Architecture section describes the high level architecture of the proposed solution. This is intended to provide the requirements for the implementers of the system. and may be adapted as the project progresses. However, it will remain a high level description - the implementation details will not be represented in this guide.
• The API section has 2 sub sections.
  • The Input API describes how data is sent from the client to the server via the RESTful API using FHIR transactions.
  • The Query API describes what queries the system needs to support.
• Examples contains a list of example resources
• Extensions is a summary of extensions
• Profiles lists the profiles defined here
• Terminology contains ValueSets needed by the profiles & extensions
• The Reference Implementation describes applications that have been created to assist with development and demonstrate the kinds of interface that could be built with the ACT-NOW data
• And finally the Support tab allows downloading of this guide and all the artifacts defined as computable resources in a number of formats, as well as a link to the main FHIR specification.
