Ontario Mental Health and Addictions Provincial Data Set – HL7® FHIR® Implementation Guide (Version 1.0.0)

The Mental Health and Addictions Provincial Data Set will be implemented in a phased approach to standardize the collection of data across the sector and lifespan. This standard will provide local service providers with discrete client level data to deliver care, and as a Prescribed Entity, Ontario Health will collect data using this standard to facilitate aggregate-level system performance measurement and service planning at local, regional, and provincial levels.

Data in scope for this release includes:

• Client data including demographics, social determinants of health, episode of care information​
• Program information including referral data, assessment dates, enrollment information, encounter data
• Health Service Provider data including organization and location information

Scope

The Mental Health and Addictions Provincial Data Set Implementation Guide is built on the HL7® FHIR® (Fast Healthcare Interoperability Resources) standard Release 4 and provides guidance to implementers on how to submit data to the MHA repository using the HL7 FHIR standard.​ It ensures all point of care systems that submit MHA data to the provincial repository do so through HL7 FHIR R4 RESTful APIs and standard terminologies.

The guide is a web-based specification hosted on the Canadian FHIR Registry powered by SIMPLIFIER.NET*. The reader will be re-directed to the implementation guide’s home page on Canadian FHIR Registry website after registering and clicking the “Agree and Download” button.

Status

This implementation guide is a Balloted Draft for trial use and is subject to a formal review and approval process.

FHIR is an evolving trial-for-use standard, so additional changes by HL7 are expected. We will continue to monitor developments and assess whether there are impacts and publish updates as they emerge.
