Background
Canada Health Infoway (Infoway) has initiated the Interoperable
Electronic Health Record (iEHR) project to set the foundation for
establishing the messaging standards by which the EHR community
in Canada will interoperate. These specifications will form the basis
of the interoperable messaging platform within the EHR Infostructure
as detailed in Infoway’s blueprint document.

iEHR Components
•
The iEHR specifications will address the requirement by the healthcare
community (Point of Service or PoS) to interact with two specific
components of the EHR Infostructure;
1. The Shared Health Record (SHR)
2. The EHR Index.
•
The SHR is primarily responsible for housing healthcare information related
to encounters, events and episodes which spans multiple business
domains; that is, information specifically identified as not belonging to an
already existing business area (e.g. Drug Information, Laboratory, and
Diagnostic Imaging)
•
The EHR Index will contain meta information about healthcare events,
episodes and encounters stored in the SHR and in domain-specific
repositories (Drug, Lab, DI). This meta data will effectively catalogue the
information to allow for easier storage to, and retrieval from the SHR and
the domain-specific repositories.
