Assessing agreement between Ontario’s birth registry and CIHI-DAD

A September 2025 publication evaluated the consistency of birth-related data between the BORN Information System and the Canadian Institute for Health Information’s Discharge Abstract Database (CIHI-DAD), which collects administrative, clinical, and demographic data on all hospital discharges. The study found excellent agreement (≥90%) across all assessed maternal data elements. These findings reinforce BORN’s value as a reliable and trusted source for researchers and policy makers across Canada. https://journals.sagepub.com/doi/10.1177/18333583251375127
