HL7-NLM EHR Project Description
EHR Overview Document
EHR Phase I
Phase I will implement a simple query-response message set executed between two EHR systems in the
following conversational format:
-
A query from an authorized requestor to a record holder asks what information could be provided
on a specific patient within supplied parameters.
-
The response provides a high level description or index of the information on that specific patient
that could be transmitted in response to the request.
-
A follow-up query requests all or a specified subset (by type and date range, for example) of the
specified patient’s information.
-
The response contains a simplified but standardized information retrieval message that has one or
more CDA documents as payload. The CDA documents, in turn, contain human-readable clinical
records plus optional source data encoded in HL7 formats.
This conversation takes place within a secure transmission mechanism that handles encryption,
segmentation, verification, and transmission over the internet. Mechanisms to move source data into and
out of these messages will also be provided.
