A narrative review of updates in deprescribing research

Abstract

Background/Objectives Deprescribing is a strategy intended to reduce harms associated with potentially inappropriate medications. Reflective of the growing interest in deprescribing, there has been an increase in related research to better understand the landscape, opportunities for improvement, how best to develop and implement interventions, and remaining knowledge gaps that can be addressed with additional study. Design We conducted a narrative review of recent deprescribing literature. Setting As part of the US Deprescribing Network's inaugural conference in October 2020, we presented a narrative review of recent deprescribing literature to an audience with a range of clinical and research expertise. Participants We searched four databases for English‐language articles published between January 1, 2019 and August 31, 2020. Measurements We evaluated titles, abstracts, and full‐length manuscripts for relevance, novelty, rigor and variety of methods; we also aimed for broad representation of authors, institutions, and nations. Results The initial search returned 199 citations, from which we reviewed 18 full‐length manuscripts, selecting 10 articles to present. Salient themes included missed opportunities to deprescribe in potentially eligible patients, with variable impact of medication‐ and patient‐level factors, along with differing perspectives and behaviors between geriatricians, internists, and cardiologists. Clinical, financial, and economic drivers were also evaluated. Finally, attention was given to issues applicable to deprescribing research, including difficulty recruiting trial participants, perspectives of investigators, and integration of findings into clinical practice. Conclusion This narrative review summarizes key advances in the field while also identifying priority areas for additional research.
