What Are Priorities for Deprescribing for Elderly Patients? Capturing the Voice of Practitioners: A Modified Delphi Process

<div><p>Polypharmacy and inappropriate medication use among older adults contribute to adverse drug reactions, falls, cognitive impairment, noncompliance, hospitalization and mortality. While deprescribing - tapering, reducing or stopping a medication - is feasible and relatively safe, clinicians find it difficult to carry out. Deprescribing guidelines would facilitate this process. The aim of this paper is to identify and prioritize medication classes where evidence-based deprescribing guidelines would be of benefit to clinicians. A modified Delphi approach included a literature review to identify potentially inappropriate medications for the elderly, an expert panel to develop survey content and three survey rounds to seek consensus on priorities. Panel participants included three pharmacists, two family physicians and one social scientist. Sixty-five Canadian geriatrics experts (36 pharmacists, 19 physicians and 10 nurse practitioners) participated in the survey. Twenty-nine drugs/drug classes were included in the first survey with 14 reaching the required (≥ 70%) level of consensus, and 2 new drug classes added from qualitative comments. Fifty-three participants completed round two, and 47 participants completed round three. The final five priorities were benzodiazepines, atypical antipsychotics, statins, tricyclic antidepressants, and proton pump inhibitors; nine other drug classes were also identified as being in need of evidence-based deprescribing guidelines. The Delphi consensus process identified five priority drug classes for which expert clinicians felt guidance is needed for deprescribing. The classes of drugs that emerged strongly from the rankings dealt with mental health, cardiovascular, gastroenterological, and neurological conditions. The results suggest that deprescribing and overtreatment occurs through the full spectrum of primary care, and that evidence-based deprescribing guidelines are a priority in the care of the elderly.</p></div

Deprescribing guidelines: an international symposium on development, implementation, research and health professional education

Deprescribing is a clinically important and feasible innovation that ensures medication efficacy, reduces harms, and mitigates polypharmacy. It involves reducing doses or stopping medications that are not useful, no longer needed, or which may be causing harm. It may also involve changing to a safer agent or using non-pharmacological approaches for care instead. Clinical guidelines combined with behaviour changes (of health care providers (HCPs), the public, and health care decision-makers) are needed to integrate deprescribing into routine practice. Using rigorous international standards, the Bruyère Research Institute Deprescribing Guidelines research team validated a ground-breaking deprescribing guideline methodology and developed or co-developed 5 evidence-based deprescribing guidelines. In March 2018, the team hosted an international symposium convening HCPs, researchers, public agencies, policymakers, and patient advocates in Ottawa, Ontario, Canada. This 3-day symposium aimed to facilitate knowledge exchange amongst guideline developers, users, and the public; initiate partnerships and collaborations for new deprescribing guideline recommendations and effectiveness research; and to continue work on HCP deprescribing education activities. An interprofessional planning committee developed an overall agenda, and small groups worked on session objectives and formats for different components: methods for rigorous deprescribing guideline development, implementation experiences, research/evaluation experiences and educational needs. Through a series of keynote speakers, panel discussions, and small working groups, the symposium provided a forum for participants to meet one another, learn about their different experiences with deprescribing guidelines, and develop collaborations for future initiatives. One hundred thirty participants, from 10 countries and representing over 100 institutions and organizations took part. Symposium proceedings are presented in this issue of RSAP for sharing with the wider community engaged in the care of patients with problematic polypharmacy
