EHR IP Summary

Description

This EHR Interoperability Profile describes the EHR Communication Steps (EHR_CS) for a user to access the EHR and retrieve a list of patient (clinical) events from multiple jurisdictions and locations.

This process includes the following two interactions with the EHRi registries and repositories

EHRS Locator - to return a list of the locations where a patient has received care recorded in multiple jurisdictions
EHR Index – Search for patient Event index entries in the EHR Index and retrieve a list of Events from one or more EHRs that match the search criteria

The EHRi System records patient Events of different types and granularity (see EHRIP15 Put Event). How patient Events are grouped together in the EHRi System is dependent on how they were related when they were recorded in the EHRi System by POS systems.

EHR IP List Events will allow POS systems to retrieve a list of Events using optional parameters such as:

The type of events required (e.g Lab Results)
The identity of a main event (HL7 Focal Act Event) other sub-events belong to
A range of dates when these events were created
A maximum number of events to be returned
The jurisdiction(s) / location(s) where this list of events is to be retrieved from

If no parameters are provided, EHR List Event will list the key attributes of all Events for a patient by date up to a default maximum from all participating jurisdictions / locations.

Examples

The following is a list of example services that would use the generic “List Event” type of interoperability profile pattern to retrieve lists of patient clinical data.

EHR IP (type List Event)	Description
List Encounters/Visits	Requests the list of available encounter related events (admission, discharge, transfers) in the EHR of a given client
List Medication Profile	Request the list of available drug related events available in the EHR of a given client
List Health Profiles	Requests a list of health profiles recorded and available in the EHR of a given client
List Provider Laboratory Results	Request a list of known laboratory results available in the EHR and destined to a specific Provider
List Location Communicable Disease Reports	Request a list of communicable disease report events for a given service delivery location or for a collection of service delivery locations

Actors

This EHR IP includes interactions between the following actors:

Actor

Description

Point of Service System (or

EHRi System Web Viewer)

The point of service system used by the Health Care Provider (user)

EHRi System

The system that contains the jurisdictional EHR for this patient.

Preconditions

The user is already authenticated and authorized and logged into the EHRi System and has identified the patient to retrieve and list events.
The client, provider and location identities have been established

Process Steps

User has selected the desired patient and proceeds with the following steps.

Process Step	POS	EHR Communication Step
User requests a list of events for the selected patient.	POS system sends a request (via POS middle tier) to the EHRi System specifying the provider identity, the client identifying information to located, an optional type of Event and an optional range of dates when the Event was recorded in an EHR	EHRCS07_Search_Patient_Information_Location (request) Communication Step Responsibilities: Locate the patient’s unique identifier in the Client Registry Locate which jurisdictions and locations where this patient has EHR Events.
	The POS middle tier receives a list of jurisdictions / locations where this patient has EHR Events.
	POS system middle tier sends query to each jurisdiction EHRi System specifying the provider identity, the client identity, and Event search criteria.	EHRCS12_List_Events (request) Communication Step Responsibilities: For each jurisdiction where the patient has information, the system retrieves a list of Events by location that match the input criteria.
	POS system receives a list of the patient’s Events by jurisdiction, service location, provider id, date and type of event.	(response)
