From detailed guides to online courses – resources are available to provide you with the knowledge necessary to build and integrate EHR applications.

Domain Repository Services

Disciplines in the health sector are referred to as clinical domains or line of business systems. 

Domain repositories are applications that collect, store, and support the use of clinical data about health care clients for a clinical domain. They also provide business services for accessing and managing the data. Examples of domain repositories include drugs, labs, diagnostic images, immunizations, and clinical data repositories.

Access to, use of, and entry/modification of information in the repositories is managed through service interfaces exposed by the HIAL. Using the HIAL creates an important level of abstraction, so that consuming systems can exchange data with these domain repositories without needing to interact with, or know the details of, their native interfaces – the consuming systems simply use a published service end point that is exposed at the HIAL.

These applications are designed to ensure that high quality data pertinent to a line of business is properly managed and adheres to the rules of that line of business. They are provincially owned and are accessible to authorized requestors. 

Data exchange with these repositories can be two-way. For example, laboratory information systems may populate lab results into the laboratory domain repository, and health care clients and providers may view lab results from the same repository. Access to the various clinical repositories, in combination, enables the user to compose a multi-disciplinary clinical picture of a health care client.
