Potentially Inappropriate Medications in Older Adults: Deprescribing with a Clinical Pharmacist

Objectives To compare the effects of a Geriatric Patient-Aligned Care Team (GeriPACT) on deprescribing of potentially inappropriate medications (PIMs) in individuals aged 80 and older with usual care (UC) in the Veterans Affairs setting. Design Retrospective cohort study. Setting Veterans Affairs Medical Center in Lexington, Kentucky. Participants Individuals aged 80 and older who filled a PIM at least 90 days before a GeriPACT or primary care appointment between January 1, 2015, and September 6, 2017 (N = 568). Measurements The primary outcome was to determine whether an interdisciplinary team (IDT) including a clinical pharmacy specialist (CPS) resulted in greater deprescribing of PIMs for older adults than UC. Results One hundred twenty-one (26.8%) PIMs were deprescribed in GeriPACT, compared with 73 (16.1%) in UC (p = <.001). Of PIMs not deprescribed, 9.7% (n = 32) were dose reduced in GeriPACT, versus 2.8% (n = 11) in UC (p < .001). Documentation of risk versus benefit discussion between a provider and participant or pharmacist and participant occurred with 65.2% (n = 215) of PIMs not deprescribed in GeriPACT and 0.003% (n = 1) in UC (p < .001). Conclusion An IDT that included a CPS led to significantly more deprescribing of PIMs in older veterans. Including a CPS on an IDT for the management of older adults can decrease PIM use in our rapidly growing aging population. J Am Geriatr Soc 67:115-118, 2019.
