TorSaDE cohort data now more available

More security and privacy

The research community in Quebec has special access to microdata from ISQ surveys, in particular the Canadian Community Health Survey (CCHS), as well as administrative data from different ministries through the Centres d’accès aux données de l’Institut de la statistique du Québec (CADRISQ). These sites allow researchers to consult data in a highly secure setting. The implementation process used by the ISQ also ensures the highest level of data confidentiality thanks to a mandatory analysis and verification process for confidentiality of results.

In early 2021, the Unité de soutien SRAP du Québec proudly announced the creation of a TorSaDE research community, naming Dr. Anaïs Lacasse, full professor at the health sciences department at the Université du Québec en Abitibi-Témiscamingue (UQAT), as its scientific director.

More access

The increased distribution of CADRISQs is excellent news for research teams in Quebec. In March 2021, Quebec hosted CADRISQs in Montreal, Quebec City and Sherbrooke. The Unit is pleased that data from the TorSaDE cohort, specifically designed to study the care trajectories of patients with sensitive conditions requiring ambulatory care, has consequently become more accessible to the research community. 

What is TorSaDE?


TorSADE is a cohort specifically designed to study the care trajectories of patients with sensitive conditions requiring ambulatory care. This project is designed to make data on care trajectories of a cohort representative of the Quebec population available to researchers.

The TorSaDE cohort consists of respondent data from various cycles of the Canadian Community Health Survey (CCHS), combined with their medical and administrative data for a 20-year period (from 1996 to 2016).

With this project, we developed a TorSaDE-specific toolbox that includes:

  • Documentation on available variable metadata.
  • A false databank that contains all variables and their relationships, with data randomly modified to test project feasibility and the strength of the programming of anticipated analyses.
  • A case selection algorithm directory for participants with sensitive conditions requiring ambulatory care.
  • A library of preprogramed complex compound variables (e.g., comorbidity index, gender, continuity of care).
  • Documentation on the different sequential analytical methods for studying care trajectories.
  • The “6W” conceptual and operational model for care trajectory analysis.

To access this toolbox, you must become a member of the TorSaDE research community by submitting a service request to the Unit.
Researchers using the TorSaDE cohort

  • Are part of a community of practice dedicated to studying care trajectories
  • Offer scientific workshops on using the cohort
  • Share methodological improvements resulting from their work
  • Have received more than $2M in complementary research subsidies and bursaries for graduate students.
