Assumptions

The nurse uses an EMR system and is already logged on this 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 nurse 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).

Workflow Event Step	POS Action	EHRi System Action	EHR IP reference
Late one night patient’s condition deteriorates markedly and he passes away. The nurses who was with patient when he died, accesses the patient record, through the EMR system, to record this event.
Resolution of patient’s identification (in the current jurisdiction)
The nurse enters the patient’s identification information in the EMR system.	The POS EMR system searches and finds locally the identification of 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 the client, in the current jurisdiction, with the provided key information (ex. name, birth date, provincial health care number) and finds the client.	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.
Record death event (in the current jurisdiction)
The nurse records the death event in the EMR system: - Date, - Time, - History, - Exam, - Action.	The POS EMR system is updated with the death event. The POS EMR system sends, to the EHRi system, an update request to record the death event for the current patient (for the EHRi Transaction Client ID).	The EHRi system adds the death event for the current patient (for the EHRi Transaction Client ID).	EHRIP15 Put Event
		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.
