Data Collection:
|
CIHI receives data directly from participating hospitals.
|
|
Sample size:
|
About 4.3 million records per annum
|
|
Geographic coverage:
|
Coverage has been increasing over time. Currently, about 85% of hospital inpatient discharges in Canada are included, consisting of all hospitals in every province and territory except Quebec and parts of Manitoba (Manitoba only submits 40% of their data) for both acute/inpatient data. It also contains Day Surgery Data for all provinces except Quebec, Alberta and parts of Manitoba. If comprehensive geographic coverage is required, the Hospital Morbidity Database may be used instead for national reporting.

Data Elements:
Selected data elements include:
- 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:
The advantages of the Discharge Abstract Database include its timeliness, value-added data elements (e.g. Case Mix Groups and Resource Intensity Weights), and coverage of same day surgery for selected jurisdictions/facilities.
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.
