Who We Are

Established in 1998, the Centre for Health Evaluation and Outcome Sciences (CHÉOS) is a group of experienced health outcomes researchers and support staff based at St. Paul’s Hospital. We evaluate the effectiveness of health interventions in populations to understand how to improve health and transform health systems for the future.

Our Research

At CHÉOS, we produce high-quality evidence to make informed changes to the health care system. CHÉOS Scientists are active in a number of clinical research areas, including cardiology, nephrology, critical care, and emergency medicine.

A major focus of CHÉOS Scientists is research surrounding the structural and intermediary determinants of health. Our work spans the areas of urban populations with research related to mental health, substance use, and infectious diseases, as well as other groups such as ethnic minorities, new Canadians, and Indigenous peoples.

Our Mandate

CHÉOS is proud to be recognized as one of Canada’s foremost health outcomes research organizations. Bridging the gap between data, research, and care, CHÉOS is a collaboration between cross-disciplinary scientists and expert research staff. The Centre influences change and improves patient care and health systems by empowering decision-makers to find positive, evidence-based solutions.

In addition to undertaking our own research, CHÉOS is dedicated to providing research support services for both health outcomes research and clinical trials.

The Centre is committed to creating an inclusive, dynamic, and cooperative work environment in which younger researchers are mentored, established researchers are supported, and all participants are encouraged to pursue personal and professional challenges.

Governing Institutions

As the primary investigator-driven health services and outcomes research centre for Providence Health Care (PHC), CHÉOS is jointly affiliated with Providence Research and the University of British Columbia (UBC) Faculty of Medicine and is housed at St. Paul’s Hospital, a teaching and research hospital in the heart of Vancouver, Canada.

Annual Reports

Each year, we release a report to summarize and celebrate the ongoing achievements at CHÉOS.
