Knowledge Synthesis Group

About Us


The Knowledge Synthesis (KS) Group, led by Dr. David Moher, joined the Ottawa Hospital Research Institute (OHRI) in 2008. It is an academic research group located at the Centre for Practice-Changing Research, Ottawa, Canada and is affiliated with the University of Ottawa. It works closely with the Ottawa Methods Centre (OHRI) and is engaged exclusively in knowledge synthesis and related methods research. The KS Group is committed to developing high quality knowledge syntheses such as systematic reviews; health technology assessments; scoping reviews; and rapid reviews. It has garnered international recognition having conducted research for and training to local, provincial, national and international stakeholders.

The KS Group is home to several international research initiatives including the Cochrane Collaboration's Bias Methods Group (BMG), the Consolidated of Reporting Initiatives for Randomized Controlled Trials (CONSORT) group; Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) group; the coordinating centre for Knowledge Synthesis (KS) Canada Network; a designated Evidence on Tap Centre by the Canadian Institutes of Health Research (CIHR); and a CIHR-designated a Drug Safety and Effectiveness Network (DSEN) Collaborating Centre for Network Meta-Analysis. The KS Group is also focused on how best to update knowledge syntheses and how best to conduct and report rapid reviews.


As mentors and global leaders in the science and conduct of clinical and methodological research, the Knowledge Synthesis (KS) Group strives to improve healthcare through evidence-based research syntheses by fostering excellence through innovation, collaboration, professionalism and transparency. 


ChalmersPrior to 2009, the KS Group was formerly the Chalmers Research Group, established in 1998 at the Children’s Hospital of Eastern Ontario Research Institute (CHEO RI).  The group was named after Dr. Thomas C. Chalmers, a highly respected and accomplished physician, researcher and administrator, who was an acknowledged leader in the design, conduct and evaluation of clinical trials and systematic reviews. Dr Chalmers went on to publish several hundred articles in his lifetime, including a landmark paper on the development of evidence-based medicine.  The KS Group endeavors to continue Dr. Chalmers’ legacy in the quest for excellence in health research.
