Data Collection:

Data are gathered from administrative separation records of psychiatric and general hospitals. Mental health data from provincial psychiatric hospitals comes from the Hospital Mental Health Survey and general hospitals from the Hospital Morbidity Database. They are obtained electronically through selected extracts of the Discharge Abstract Database for those provinces/territories participating in DAD. Data files for the remaining hospitals are submitted by the appropriate province or territory.

Data Elements: Selected data elements include:
- Demographic information (age, sex, birth date, marital status)
- Medical diagnosis
- Admission/ separation information
Notes: Data are based on inpatient events only and exclude patients treated as outpatients, in residential care facilities and group homes, and in community-based mental health services.
Data are reported based on the region of the patient's residence, not region of hospitalization. Consequently, these figures reflect the hospitalization experience of residents of the region wherever they are treated as opposed to the comprehensive activity of the region's hospitals. It represents how frequently residents of a given area received hospital care rather than the volume of services provided by hospitals.
