The Ontario Mental Health Reporting System (OMHRS) analyzes and reports on information submitted to CIHI about all individuals receiving adult mental health services in Ontario, as well as some individuals receiving services in youth inpatient beds and selected facilities in other provinces. OMHRS includes information about mental and physical health, social supports and service use, as well as care planning, outcome measurement, quality improvement and case-mix funding applications.
Find out more about inpatient mental health services, including reports and analyses based on OMHRS data.
OMHRS comprehensive data is collected using the Resident Assessment Instrument — Mental Health (RAI-MH©) version 2.0, a standardized clinical instrument used to regularly assess those receiving inpatient mental health care. The RAI-MH gathers information on where individuals are admitted from and why, where they are discharged to and why, and, potentially, information at other points in time during a hospital stay.
The tool was developed by interRAI , Ontario’s Ministry of Health and Long-Term Care and the Ontario Hospital Association. It includes the following:
- The Minimum Data Set for Mental Health (MDS-MH)©, with approximately 300 data elements
- 20 Mental Health Clinical Assessment Protocols (MH CAPs)© for care planning
- 5 Quality Indicators for Mental Health (QIMH)
- 7 outcome measures based on clinical scales
- The System for Classification of In-Patient Psychiatry (SCIPP) case-mix methodology
Assessments are completed
- At admission
- At discharge
- Every 3 months, for patients with extended stays
- Whenever there is a significant, unexpected change in a patient’s clinical status
Data is currently submitted to CIHI from participating hospitals in Ontario, as well as from 2 pilot facilities in Newfoundland and Labrador and 1 pilot facility in Manitoba. Data is available from October 1, 2005, onward.
OMHRS data is available by fiscal quarter, with a 2-month lag period following each fiscal quarter. OMHRS data is currently available for the following fiscal years:
- Most recent year: 2017–2018
- Historical data: 2005–2006 to 2016–2017
For data from 2005–2006 to 2016–2017, please complete a data request form.
Case-mix methodologies (a form of resource measurement) categorize assessment data into homogenous groups based on the administrative and clinical data collected. This information can be used to understand the different care requirements of clients by comparing health care organization and case-mix resource use.
OMHRS uses the System for Classification of In-Patient Psychiatry (SCIPP) that was developed for the RAI-MH.
The OMHRS data elements in the MDS-MH are organized into the following sections:
- Patient identifiers
- Personal items
- Referral items
- Mental health service history
- Assessment information
- Mental state indicators
- Substance use and excessive behaviours
- Harm to self and others
