“…These programs have catalyzed new scholarship and future grant-supported research, particularly in populations with dementia, multimorbidity, and other vulnerabilities, with networksupported investigators publishing many hundreds of papers relevant to deprescribing science and obtaining a wide variety of grants on the topic. [3][4][5] Working groups, a data harmonization initiative, and resource development programs (all hosted at https://deprescribingresearch.org/) have created resources and established evidence-based best practices on foundational topics in deprescribing science. These topics include identifying high-value targets for deprescribing, consensus outcome measures to use in deprescribing studies, guidance on measuring deprescribing using data from electronic health records, and an ongoing project to identify best practices in deprescribing communication.…”
