Having a solid picture of the proportions of separations and the trends over time provides health system planners and other decision-makers with information to plan care and evaluate the performance of their health care system.

This indicator provides a measure of hospital utilization and may reflect differences in the health of the population and mental health service delivery models as well as variations in the availability and accessibility of specialized, residential and/or ambulatory and community-based health services.

2016–2017: For records from the Ontario Mental Health Reporting System (OMHRS) — one of the data sources that populates the Hospital Mental Health Database (HMHDB) — broad mental health category in the HMHDB was assigned based on the DSM-5 diagnosis category instead of the specific diagnosis code.

The assignment of diagnosis codes to diagnosis categories was modified. Several ICD-10-CA and DSM-IV-TR diagnosis codes were regrouped into HMHDB broad mental health categories. These changes decreased the volume of separations in the Anxiety Disorders broad mental health category and increased the volume of separations in the Other Disorders category.

As this indicator excludes psychiatric hospitals, it should not be construed to represent all mental health and addiction hospital separations in Canada.

Certain cells were suppressed for confidentiality reasons in accordance with CIHI's privacy policy. Totals exclude suppressed values.

Many factors contribute to the observed variations in the analysis of indicators at the provincial/territorial and regional levels. These include, but are not limited to, geography, population health, provincial and regional health service resources, and health services administration. It is important to consider these factors and the effect they may have on indicator results when conducting comparative analyses. The variation in results between provinces/territories or between health regions suggests systematic differences in

–Provincial/territorial or regional health policies, practices and resources
–Geography and urban/rural population distribution
–Environmental and socio-economic characteristics
–Types of patients served and acuity of illness
–The range of health services available beyond general and specialty psychiatric hospitals (such as community mental health services)
–Accessibility and awareness of alternative points of entry to the health system

The above list suggests a few of the factors that should be considered when making provincial/territorial and/or regional comparisons.

2011–2012: Additional ICD-10-CA diagnosis codes were added to the extraction criteria for the Discharge Abstract Database–Hospital Morbidity Database (DAD-HMDB), one of the data sources that populates the Hospital Mental Health Database (HMHDB). This increased the volume of separations.

2011–2012: Additional ICD-10-CA diagnosis codes were added to the extraction criteria for the DAD-HMDB, one of the data sources that populates the HMHDB. This increased the volume of separations.

2014–2015: Two ICD-10-CA diagnosis codes were removed from the extraction criteria for the DAD-HMDB, one of the data sources that populates the HMHDB. This decreased the volume of separations.

2016–2017: For records from the Ontario Mental Health Reporting System (OMHRS) — one of the data sources that populates the Hospital Mental Health Database (HMHDB) — broad mental health category in the HMHDB was assigned based on the DSM-5 diagnosis category instead of the specific diagnosis code.

The assignment of diagnosis codes to diagnosis categories was modified. Several ICD-10-CA and DSM-IV-TR diagnosis codes were regrouped into HMHDB broad mental health categories. These changes decreased the volume of separations in the Anxiety Disorders broad mental health category and increased the volume of separations in the Other Disorders category.

Separations by year are based on the date of discharge, not the date of admission. As such, records with invalid discharge dates are not included.

The HMHDB is an event-based rather than a person-based database; individuals may be represented multiple times in the data.

For 2006–2007, 2007–2008, 2008–2009, 2009–2010, 2011–2012, 2012–2013, 2013–2014, 2014–2015 and 2015–2016, crude rate calculations at the provincial/territorial level are based on population estimates from Statistics Canada as of July 1, 2006, 2007, 2008, 2009, 2011, 2012, 2013, 2014, 2015, 2016 and 2017, respectively.

For 2010–2011, crude rate calculations at the provincial/territorial level are based on population estimates from Statistics Canada as of October 1, 2010.

For 2006–2007, 2007–2008, 2008–2009, 2009–2010, 2011–2012, 2012–2013, 2013–2014, 2014–2015 and 2015–2016, crude rate calculations at the regional level are based on population estimates from Statistics Canada as of July 1, 2006, 2007, 2008, 2009, 2011, 2012, 2013, 2014, 2015, 2016 and 2017, respectively.

For 2010–2011, crude rate calculations at the regional level are based on population estimates from Statistics Canada as of October 1, 2010.

Standardized rates are age-adjusted using a direct method of standardization based on the July 1, 2011, Canadian population. For data years prior to 2014–2015, rates were age-adjusted using a direct method of standardization based on the July 1, 1991, Canadian population.
