HSUS-T1FF-CENSUS-NHS (High System Users linked to T1 Family File - Census of the Population Long-Form - National Household Survey)


Linked data on high users of in-hospital health care services now available in Research Data Centres across Canada.
Statistics Canada and the Canadian Institute for Health Information (CIHI) are pleased to announce the release of an integrated dataset that will allow researchers to analyse the socio-demographic, socio-economic, and health characteristics of higher users of the health care system compared to controls drawn from the population of non-high system users. 
As part of its data integration activities, Statistics Canada has linked information about high users of the health care system to the Annual Income Estimates for Census Families and Individuals (T1 Family File), the 2006 Census of Population Long-Form (2006 Census 2B), and the 2011 National Household Survey (2011 NHS) in order to add demographic and economic information to the cohort.
CIHI is collaborating with Statistics Canada to make the integrated data available in the Research Data Centers and to support researchers using the file.
The integration of sociodemographic and socio-economic data from Statistics Canada 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 datasets alone.
About the Data:
A cohort of higher system users and controls drawn from the non-higher system user population was created using the Dynamic Cohort of Complex High System Users algorithm, developed by the Canadian Institutes of Health Research (CIHR). This cohort was based on data from the Discharge Abstract Database, the National Ambulatory Care Reporting System and the Ontario Mental Health Reporting System (OMHRS) for fiscal years 2011/2012 to 2014/2015. The cohort was linked to the T1 Family File (2006 to 2014), the 2006 Census of the Population Long-Form and the 2011 National Household Survey.
