The Ontario Mental Health Reporting System (OMHRS) is a new data holding at CIHI that includes clinical, administrative and resource information to support inpatient mental health services planning. The OMHRS database captures information on all adult inpatient mental health beds in Ontario. Collection commenced with new admissions after October 1, 2005.

The Ontario Mental Health Reporting System incorporates the RAI-MH© version 2.0 instrument as well as admission and discharge tracking-related data elements. The Resident Assessment Instrument–Mental Health (RAI-MH) is a unique standardized data collection system for mental health, which is designed to include care planning, outcome measurement, quality improvement and case mix based funding applications.

The RAI-MH is a suite of products that includes:

  • The Minimum Data Set for Mental Health © (MDS-MH) with approximately 300 data elements;
  • 28 Mental Health Assessment Protocols © (MHAPs) for care-planning;
  • 32 Quality Indicators for Mental Health (QIMH), 12 Outcome Measures based on clinical scales; and
  • The System for Classification of In-Patient Psychiatry (SCIPP), the case-mix methodology developed for use with the MDS-MH data.


The Ontario MOHLTC has mandated mental health reporting using the RAI-MH data collection system (Resident Assessment Instrument–Mental Health, version 2.0) in all hospitals with designated adult inpatient Mental Health beds. This mandate involves approximately 70 facilities in Ontario, including general hospitals with designated adult inpatient mental health beds, as well as specialty psychiatric hospitals and provincial psychiatric hospitals. These facilities are required, under the mandate, to collect clinical and administrative data using the RAI-MH. CIHI is implementing OMHRS on behalf of the Ontario Ministry of Health and Long-Term Care (MOHLTC). CIHI has developed technical solutions to support data submission and reporting and will continue to manage client support, including education and ongoing training for participating OMHRS facilities.

The OMHRS database is scalable, designed for pan-Canadian usage and expansion of the reporting system to other Canadian jurisdictions is expected in the coming years. For inquiries related to RAI-MH mental health reporting or education in Canada, please contact the OMHRS team at CIHI.

OMHRS Reports

As part of the reporting system, OMHRS provides province, facility and unit level quarterly comparative reports to participating mental health facilities. These reports detail the rate and prevalence trending for six quality indicators and four clinical scales. OMHRS quarterly comparative reports are designed to aid in decision support and inform policy and planning. The peer and provincial comparators allow facilities to gauge their indicators in context and afford further benchmarking opportunities.
OMHRS also produces quarterly data quality reports for facilities that include information on ten key indicators giving a quarterly snapshot of facility level data quality. The indicators include, for example, such items as use of “unknown” coding and the integrity of patient episodes.
OMHRS reports are provided only to participating facilities that have signed the eOMHRS Service Agreement. Contact the OMHRS team for more information on eOMHRS.
