Replication of studies and systematic reviews: why, when, and how?


Brigitte Vachon is an occupational therapist and associate professor at the School of Rehabilitation in the Faculty of Medicine at the Université de Montréal. She is a researcher at the Centre de recherche du CIUSSS de l’Est de Montréal as well as an associate researcher at the CISSS Laval. Her research activities focus on the continuous quality improvement of primary care and rehabilitation services offered to people with chronic conditions. She is particularly interested in the evaluation of knowledge translation strategies based on reflexive and collaborative learning processes.



Sathya Karunananthan holds a PhD in epidemiology from McGill University. As a postdoctoral fellow at the Bruyère Research Institute, she is conducting work in the areas of frailty and physical function in older persons, and the role of technology in improving access to healthcare. She is also involved in projects on systematic review methodology, meta-research, and healthcare knowledge translation. Her recent work includes the development of guidance for when to replicate systematic reviews.
