The Hospital Mental Health Database (HMHDB) contains data from all provinces and territories in Canada on hospitalizations for mental illness and addiction.
HMHDB data is gathered from administrative separation records of psychiatric and general hospitals from 4 sources:
- Discharge Abstract Database (DAD): Separation records from psychiatric hospitals participating in the DAD
- Hospital Morbidity Database (HMDB): Separation records from psychiatric hospitals in Quebec and selected acute separation records from all provinces and territories
- Hospital Mental Health Survey (HMHS): Separation records from selected psychiatric hospitals that do not report to the DAD
- Ontario Mental Health Reporting System (OMHRS): Separation records for individuals admitted as inpatients to adult mental health services in Ontario as well as some individuals in youth inpatient beds and selected facilities in other provinces
Inpatient hospital stays from all provinces and territories are represented in the HMHDB. The HMHDB includes general and psychiatric hospitals.
