This database collects demographic and clinical information for inpatient separations (discharges/deaths) from Canada's general and allied special hospitals. It is similar to the Discharge Abstract Database, but only contains Acute/Inpatient data and national level data and has fewer data elements.

Maintained by:
|
CIHI; prior to 1994, database maintained by Statistics Canada
|
|
Availability:
|
Data disclosure is determined by CIHI's Privacy and Confidentiality Policy (see www.cihi.ca). In some instances, CIHI and Statistics Canada manage release of information jointly. If privacy and confidentiality criteria are met, data can be released at the sub-provincial level. Costs are dependent upon the level data required, plus programming and processing fees.

Data Elements:
- Most responsible physician/diagnosis
- Principal procedure
- Patient gender, date of birth, postal code, institution/hospital number
- Admission/discharge, (e.g. admission category, length of stay)
Notes:
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.
Discharges from any outpatient services in any hospital and discharges from psychiatric hospitals are not contained in this database. Data for hospitalization for mental illnesses across Canada can be found in the Hospital Mental Health Database.
