These guidelines will support interdisciplinary teams of healthcare professionals in tapering or stopping medications that may be causing harm or are no longer providing benefit as well as monitoring for adverse drug withdrawal reactions in elderly patients. The project’s research team expects that this will reduce adverse drug effects and improve quality of life.
Deprescribing guidelines and their team members
The project has assembled three teams of dedicated researchers and healthcare professionals to develop the guidelines.
Guideline team 1: Proton pump inhibitors — This team has developed a deprescribing guideline for PPIs, a class of drugs that reduce acid production in the stomach. They are commonly used to treat heartburn, among other conditions.
Guideline team 2: Benzodiazepines — This team has developed a deprescribing guideline for benzodiazepine receptor agonists, a class of drugs also called hypnotics or sedatives that are commonly prescribed for insomnia, among other conditions.
Guideline team 3: Antipsychotics — This team is developing a deprescribing guideline for antipsychotics, a class of drugs used to treat psychosis and schizophrenia, among other conditions.

- To determine which consensus, development and implementation processes can be used to create and introduce deprescribing guidelines into primary and long-term care to influence the adoption and use of the practices described in the guidelines.
- To determine the uptake and effect, including projected savings, of deprescribing guidelines in primary and long-term care settings.
- To determine the effect of deprescribing guidelines on prescriber self-efficacy in discontinuing medications and patients’ acceptance of deprescribing.
This project uses both qualitative and quantitative methods to evaluate the process of developing and implementing deprescribing guidelines in three long-term care and three family health team practices in Ottawa.
Priorities for guideline development were determined through a consensus process that involves experts in geriatric medicine, long-term care, primary care, and guideline development (see the publication describing this process). Guideline development and implementation teams have been formed, and three sets of guidelines are being developed, implemented and evaluated.
A variety of research and evaluation methods are being used to ensure that the guidelines are based on a rigorous development process and are relevant and useful for deprescribers. Observations of and interviews with the guideline development teams are being used to understand the process of prioritizing and developing guidelines. Observations of and interviews with members of the site implementation teams are being employed to capture additional detail on the progress and process of guideline implementation and ongoing development.
Pre–post surveys will assess changes to physicians’ perceived self-efficacy to taper or stop medications. The patients’ perspectives and experiences of the process will be captured through semi-structured interviews.
- Development of feasible, effective deprescribing guidelines and support tools, such as deprescribing algorithms
- Creation of an adaptable implementation process for use with other drugs and for implementation in a variety of healthcare contexts
- Generation of an outcomes evaluation approach to determine clinical and economic impacts
The results of the study will help reduce medications that may be causing problems or are no longer needed for older patients. The results will help to improve medication-related health of seniors — i.e., fewer medications taken, fewer adverse drug reactions, etc. — improve the confidence of clinicians in tapering or stopping medications and support a cultural shift in healthcare toward reassessing medication use as people age.

To continue this important work, Drs. Barbara Farrell and Cara Tannenbaum recently joined forces with a number of other interested colleagues to establish CaDeN — the Canadian Deprescribing Network — through a CIHR-PHSI grant to catalyze action and promote deprescribing across Canada.
