Discharge Abstract Database – National Ambulatory Care Reporting System – Ontario Mental Health Reporting System linked to Canadian Vital Statistics Death Database

Overview

Summary

New Hospitalization data linked to death data is now available in Research Data Centres across Canada. As part of its record linkage activities, Statistics Canada has linked the patient records in the Discharge Abstract Database (DAD), the National Ambulatory Care Reporting System (NACRS) and the Ontario Mental Health Reporting System (OMHRS), which are provided to Statistics Canada annually by the Canadian Institute for Health Information (CIHI), to the Canadian Vital Statistics Death Database. These linked data can be used to develop and validate health care indicators and perform survival and outcome analyses on acute hospital data.

The linking of Vital Statistic Death data with provincial administrative data held by CIHI creates a valuable dataset that can provide answers to important research questions that cannot be found in single administrative datasets alone. Statistics Canada has a long history of creating and using record linkages. Record linkage is an important and cost-effective statistical technique used to develop data products that support advanced research and provide insight on important social issues, such as health outcomes and disparities in subsectors of the Canadian population. The Discharge Abstract Database (DAD) (2000/2001 to 2022/2023), the National Ambulatory Care Reporting System (NACRS) (2002/2003 to 2022/2023) and the Ontario Mental Health Reporting System (OMHRS) (2005/2006 to 2022/2023) linked to the Canadian Vital Statistics Death Database (CVSD) (January 1, 2000 to December 31, 2022) dataset is now accessible at Statistics Canada’s Research Data Centres across the country.
