Core Data Elements
The COVID-19 Immunity Task Force (CITF) and its Field Studies Working Party have developed a standardized list of core data elements that must be integrated into surveys conducted by CITF-funded groups across Canada studying issues related to COVID-19 immunity.
CITF encourages the Canadian community of academic researchers, public health leaders, and staff in national health agencies to use the standardized CORE Data Elements to inform the development of new surveys or the revision of existing surveys.
Questions asked by Statistics Canada and other surveys used by national organizations formed the basis for the survey core data elements document, which aims to encourage groups to acquire and record survey data in a standardized manner.
Specifically, the core data elements include questions and responses related to COVID-19 status, COVID-19 symptoms, housing, risk factors, risk acquisitions, and health behaviours related to the virus as well as other areas of inquiry. The purpose of this list of core data elements is to ensure that gathered data is both useful on its own and is directly comparable between different COVID-19 studies and initiatives across Canada.
Likewise, a standardized reporting module for serological assays was developed. As much as possible, given the evolving pandemic, international standard coding schemes are used.
