Assumptions

The anaesthetist is already logged on the hospital’s EMR system.
To resolve the patient’s identification, the provincial health care number is also used, because it is key information to find the patient. In this case, the anaesthetist uses the following key information to find the patient: name, birth date, and provincial health care number.
The resolution of the patient’s identification information is also necessary to obtain a “temporary” unique patient identifier from the EHR, to allow the user to view and update the patient’s record. The “temporary” unique patient identifier (EHRi Transaction Client ID) is provided by the EHRi only for one user session (without a break in the time), for the same patient and the same provider (person) who are engaged in the health service event. If there is an interruption during a health service, this becomes another health service event, and another resolution of the patient’s identification is required to obtain another “temporary” unique patient identifier (EHRi Transaction Client ID).
The “health profile” is an organized collection of specific events, whose definition depends on practices of each organization and jurisdiction.
The grouping of events realized during a same “encounter” depends and varies according to the functional capacities of the POS. The definition of an “encounter” also depends on clinical practices of every organization and jurisdiction. In this case, the POS has the capacity to group the events in an “encounter”.

Workflow Event Step	POS Action	EHRi System Action	EHR IP reference
Resolution of patient’s identification (in the current jurisdiction)
Before the patient is taken to the OR, the anaesthetist accesses patient’s record and enters patient’s identification information in the hospital’s EMR system.	The POS EMR system searches locally and finds the patient. The POS EMR system sends, to the EHRi system, a request with the key information (ex. name, birth date, provincial health care number) (and to obtain a EHRi Transaction Client ID).	The EHRi system searches and finds for the client in the current jurisdiction, with the provided key information (ex. name, birth date, provincial health care number).	EHRIP10 Search Patient
		The EHRi System Client Registry returns, to POS system, the corresponding patient record (with a EHRi Transaction Client ID).
	The POS EMR system displays the corresponding record of current patient.
Consultation of the patient’s health profile (for the current jurisdiction)
The anaesthetist does a request through the hospital’s EMR system to review the patient’s health profile.	The POS EMR system sends, to the EHRi system, a search request to obtain the patient’s health profile for the current patient (for the EHRi Transaction Client ID).	The EHRi system searches and finds (in current jurisdiction) the information of health profile for the current patient (for the EHRi Transaction Client ID).	EHRIP09 Get Patient Health Profile
		The EHRi system returns, to POS system, the health profile for the current patient.
	The POS EMR system receives, organizes and displays the patient’s health profile.
View a specific referral (in the current jurisdiction)
The anaesthetist does a request, through the hospital’s EMR system, to access the pre-operative physical exam report that was done by the other physician two weeks ago (with specific criteria).	The POS EMR system sends, to EHRi system, a request to retrieve the desired pre-operative physical exam report for the current patient (for the EHRi Transaction Client ID).	The EHRi system searches and retrieves the pre-operative physical exam report event for the current patient (for the EHRi Transaction Client ID).	EHRIP13 Get Event (Event Type = pre-operative physical exam report ID)
		The EHRi returns, to POS system, the pre-operative physical exam report event for the current patient (for the EHRi Transaction Client ID).
	The POS EMR system receives and displays the pre-operative physical exam report .
The anaesthetist reviews the pre-operative physical exam report.
Record patient’s assessment (in the current jurisdiction)
The anaesthetist assesses patient herself, by taking a history and performing a physical exam.
The anaesthetist records the findings in the hospital’s EMR system: - History, - Past medical/surgical history, - Pre-op physical exam, - Orders, - Intra-op findings, - Post-op findings.	The POS EMR system is updated with the anaesthetist record. The POS EMR system sends, to the EHRi system, an update request to record the anaesthetist record and to link this event with a specific health service encounter for the current patient (for the EHRi Transaction Client ID).	The EHRi system adds the anaesthetist record event and links it with the specific health service encounter for the current patient (for the EHRi Transaction Client ID).	EHRIP15 Put Event (Event Type = anaesthetist record)
		The EHRi system returns, to POS system, an acknowledgment that the update request is completed.
	The POS EMR system displays an acknowledgment about the completed update request.
