This page contains information about CIHI’s data holdings related to acute care.
Discharge Abstract Database
The Discharge Abstract Database (DAD) contains demographic, administrative and clinical data on inpatient hospital discharges. Facilities in all provinces and territories except Quebec are required to report to the DAD. Quebec acute inpatient records are submitted to CIHI through a different process and are included in the Hospital Morbidity Database.
Hospital Morbidity Database
The Hospital Morbidity Database (HMDB) is a national data holding that captures administrative, clinical and demographic information on hospital inpatient events. It contains inpatient data collected via the DAD and inpatient records submitted from Quebec. Please note that Quebec day surgery records are part of the HMDB population as of 2012–2013.
