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


To ensure that EHR information is secure, reliable, and consistent, anyone who uses EHR services or who is included in information requests must be clearly identified. Any request to access sensitive PHI must include unique and unambiguous identification of the requestor, the requestor’s location (a legislative requirement under privacy law), the health care client, and any other individuals referenced by the request. The appropriate business rules must then be applied, including consent directives, and the access to PHI logged in an audit log.

Registries maintain the key reference information required to support health information exchange. They provide search and resolution services so that participating systems can query the registry in order to validate or obtain the formal and normalized identifier to reference an entity (such as a provider, client, or organization).

Records containing identification of health care clients and providers come from multiple sources, some of which may use identifiers that are only valid locally. The provincial registries support the concept of enterprise-wide identifiers to provide a common link for all identifiers for the same person, as required by the line of business. 

The registries will contain current, trusted information about health care clients, health care providers, EHR users, consent, systems, and terminology. They will serve as definitive reference sources for unambiguous identification and verification. As the EHR and ehealth evolve, requirements for additional types of registries may be identified.

Registries not only include reference data, but also basic functionality that allows data to be managed (e.g. put, get/search) by authorized users in accordance with applicable privacy law.
