Introduction

Overview

This Ontario Mental Health and Addictions Provincial Data Set HL7 FHIR Implementation Guide (MHA PDS HL7 FHIR IG) is written to support implementers with the submission of data from health service providers operating in the mental health and addictions domain. This implementation guide will provide guidance to implementers submitting their organization's client data to the Mental Health and Addictions Provincial Data Set Repository (MHA PDS Repository).

The Ontario Mental Health and Addictions Provincial Data Set HL7 FHIR Implementation Guide defines the required data based on the Mental Health and Addictions Provincial Data Set, and is built on the FHIR® (Fast Healthcare Interoperability Resources) standard Release 4.0.1. It provides guidance to implementers on how to submit data to the MHA PDS Repository using the HL7 FHIR standard.​ The guide ensures all Point of Service (PoS) systems that submit MHA data to the provincial repository do so through HL7 FHIR R4.0.1 RESTful APIs and standard terminologies.

Digital Health Information Exchange (DHIEX)

On January 1, 2021, an amendment to Ontario Regulation 329/04 (“O. Reg. 329/04” or the “regulation”) came into force to establish the DHIEX framework for interoperability specifications, as set out in sections 26 to 34 of the regulation. As a cornerstone of the Ministry of Health’s Digital First for Health Strategy, the DHIEX framework is intended to guide and support adoption of modern interoperability specifications for seamless access to integrated records of personal health information. In accordance with the regulation, Ontario Health is required to, subject to the review and approval of the Minister, establish, maintain and amend interoperability specifications for digital health assets selected, developed or used by health information custodians.

In accordance with O. Reg. 329/04, a health information custodian is required to ensure that every digital health asset that it selects, develops or uses complies with every applicable interoperability specification, as it may be amended from time to time, within the time period set out in the specification. Compliance with this requirement does not relieve a health information custodian of its obligation to comply with the other provisions of PHIPA and its regulations.
