EHR IP Summary

Description

This EHR Interoperability Profile describes the process for a user / system to correct a patient Event in the EHRi system. A patient’s Event may be corrected (made obsolete) if it is found to contain incorrect data.

The following steps describe the business process to correct an Event in the EHR:

1. An EHR Event “A” is identified as being incorrect and is retrieved from the EHR to the POS system either by the original author, or a user authorized to make a correction. The unique Event identifiers are passed to the POS system at the same time.

2. The POS system user initiates an “EHRIP Correct Event” interaction with the EHR

2.1. Event “B” is created in the EHR to record that Event A is incorrect and obsolete
(Communication Step EHRCS15 Put Event)

2.2. Event “C” is created in the EHR as the new correct replacement version of Event “A”
(Communication Step EHRCS15 Put Event)

Notes:

Steps 2.1 and 2.2 are two communication steps that take place inside EHRIP Correct Event.
Step 2.2 is a mandatory part of this process – a correct replacement Event must be provided
The end result is that Events “B” and “C” are "linked" to the original Event “A” in the EHR.

If the original Event being corrected is linked to an Encounter, it is the POS system’s responsibility to provide the common attribute values to ensure the new correction Events created in the EHR belong to the same Encounter.

Each newly created correction Event is linked to a Patient as a Patient Role to identify the patient’s role while receiving services by this provider at this health service location.

The EHRi system will create a unique entry in the EHR Index for each newly created correction Event using attributes derived from Put Event payload information as well as already established user and location identifiers.

If changes to the patient’s consent / data masking directives are included with this Event, they are recorded in the patient’s consent record in the Consent Registry.

EHR Business Requirement reference

This EHR IP is used by the following Clinical Activities:

Clinical Activity Document Id	Name
D03 CLACT11 D* EHR 11.1.3	Error Correction

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 to access the EHRi system and has identified the patient in the POS to store an Event.
The service location id and the provider id that requested this process have been established in previous interactions
The event to be corrected has been uniquely identified and retrieved by the POS system

Process Steps

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

Process Step	POS	EHR Communication Step
User / system requests to correct an Event in the EHRi system.	POS System sends a notification to the EHRi system specifying the provider identity, the client identity and the identity of Event to be incorrect and obsolete. If needed, consent directives would be sent in the same interaction.	EHRCS15_Put_Event
	EHRi system responds with the status of the Communication Step interaction	(response)
The POS middle tier system sends the correct Event to be recorded the EHRi system.	POS System sends a notification to the EHRi system specifying the provider identity, the client identity and the Event details of the correct replacement Event. If needed, consent directives would be sent in the same interaction.	EHRCS15_Put_Event
	EHRi system responds with the status of the Communication Step interaction	(response)
