Databases and data sources

National Ambulatory Care Reporting System

The National Ambulatory Care Reporting System (NACRS) contains data on hospital-based and community-based ambulatory care: day surgery, outpatient and community-based clinics and emergency departments.

Client visit data is collected at the time of service in participating facilities. Data collection methods may vary by facility.

Data submission

CIHI does not mandate data submission to NACRS. Provincial/territorial ministries of health and/or governing bodies that wish to collect ambulatory care data may mandate data collection in their jurisdictions.

The National Ambulatory Care Reporting System is one of CIHI’s 2 core clinical administrative databases. It contains data on emergency and ambulatory care visits, such as those at day surgery and outpatient clinics. For more information, please email cad@cihi.ca.
