Research interests

Dr. Hayden leads the BACK Program with two arms of clinical epidemiology research: 1. Prognosis research, and 2. Systematic review research – both arms are funded through multi-year CIHR grants.  For many years, she has contributed to the Cochrane Collaboration. Her research is broadly related to improving the quality and use of research evidence for more effective health care decision-making and improved patient outcomes.
