About Us

This website was developed in 2015 to host deprescribing guideline resources and related research. This work is co-led by Drs. Barbara Farrell, Lisa McCarthy and Wade Thompson.

Our Vision and Mission

Our vision for this website is to share and exchange information about deprescribing approaches and deprescribing research with the public, health care providers and researchers.                    

Our mission is to offer:

  1. Tools to help patients and providers participate in deprescribing
  2. Information about ongoing and completed deprescribing initiatives and research                  projects in Canada
  3. Links to people around the world who are interested in deprescribing


Barbara Farrell

Barbara Farrell

Pharmacist, Researcher

Dr. Barbara Farrell is passionate about deprescribing – especially for frail older adults. As a pharmacist working in the Bruyère Geriatric Day Hospital since 1999, she sees many older people often taking more than 20 medications a day. Working closely with physicians, an interprofessional team and the patients and their families, she is able to help reduce or stop medications safely. More frequently than not, this helps patients feel better, be less confused, fatigued and dizzy. These experiences prompted Dr. Farrell to pursue research in the field of deprescribing and models that improve medication-related care for older people.

Dr. Farrell is a Senior Investigator with the Bruyère Research Institute (BRI) and the CT Lamont Primary Health Care Research Centre, an Assistant Professor with the Department of Family Medicine, University of Ottawa, and an Adjunct Assistant Professor with the School of Pharmacy, University of Waterloo. She is also a member of the Ontario Pharmacy Evidence Network and is co-founder of the Canadian Deprescribing Network.

Dr. Farrell’s research team developed rigorous methodology for constructing evidence-based “deprescribing guidelines” and have developed related tools that are now used worldwide. The guidelines and tools have been endorsed and supported by organizations such as the College of Family Physicians of Canada, the Canadian Pharmacists Association, Choosing Wisely Canada, CADTH, the Canadian Institute for Health Information and the Institute for Healthcare Improvement. Dr Farrell continues to conduct research examining the implementation and effect of using deprescribing guidelines.

In 2011, Dr. Farrell was named the Canadian Pharmacist Association’s “Pharmacist of the Year” for her work in pharmacist education, patient-centred care and research. In 2018, she received the Ontario Pharmacists Association “Exceptional Achievement in Research and Academia” award, and in 2019, the CIHR Betty Havens Prize for Knowledge Translation in Aging.

Lisa McCarthy

Lisa McCarthy

Dr. McCarthy’s current practice is with Seniors Care Services at Trillium Health Partners in Mississauga, Ontario.

Dr. McCarthy has been a long-time member of the Deprescribing Guidelines Research team at Bruyère. She co-leads with Dr. Farrell, research initiatives in the area of prescribing cascades and deprescribing in long-term care. She is an executive member of the Ontario Pharmacy Evidence Network and member of the Canadian Deprescribing Network. She is co-leading development of a special interest group for the US Deprescribing Research Network. In 2020-21, she co-chaired Ontario Health (Quality)’s Medication Safety Quality Standard Advisory Committee.

Dr. McCarthy has received awards for mentorship and recognizing the accomplishments of strong teams that she has led. In 2021, Dr. McCarthy received the Ontario Pharmacists Association “Exceptional Achievement in Research and Academia” award.


Wade Thompson

Wade Thompson

Dr. Wade Thompson is a deprescribing researcher and clinician with more than a decade of experience studying and evaluating strategies to reduce unnecessary medication use to improve the well-being of older adults. He is dedicated to finding ways to ensure older adults are only taking medications that are effective, safe, and consistent with their healthcare goals and treatment preferences. Dr. Thompson’s research is inspired by his experiences as a pharmacist in long-term care and primary care, working with older people and other healthcare providers to improve older persons’ wellbeing by safely reducing or stopping medications when they are no longer a good fit.

Dr. Thompson is an Assistant Professor at the University of British Columbia in the Department of Anesthesiology, Pharmacology and Therapeutics. He completed his his BScPhm and PharmD at the University of Waterloo School of Pharmacy, MSc in Clinical Epidemiology at the University of Ottawa, and his PhD at the University of Southern Denmark.

The Ontario Pharmacy Evidence Network (OPEN) is a team of multidisciplinary researchers working together to evaluate the quality, outcomes and value of medication management services that pharmacists and other healthcare professionals provide. We are fostering knowledge translation and exchange, building capacity in medication management research, and addressing the needs of Ontario’s vulnerable populations.


The Institut universitaire de gériatrie de Montréal (IUGM) is the Quebec leader in clinical practice, specialized care, health promotion and development of knowledge related to aging and seniors’ health.

Its research center is renowned as the largest of its kind throughout French-speaking countries, and brings together activities from contribution of numerous teams from various healthcare sectors.


The Canadian Institutes of Health Research (CIHR) was created in 2000 under the authority of the CIHR Act, and is the Government of Canada’s health research investment agency. CIHR’s mandate is to “excel, according to internationally accepted standards of scientific excellence, in the creation of new knowledge and its translation into improved health for Canadians, more effective health services and products and a strengthened Canadian health care system.

“In 2013, $419 million was spent on potentially inappropriate medications for seniors outside of hospital settings, in six Canadian provinces.”
