Pharmacist interventions to deprescribe opioids and benzodiazepines in older adults: A rapid review

Many older adults are prescribed opioids and benzodiazepines (BZDs), despite increased susceptibility to adverse events. Challenges of deprescribing include fragmented care and lack of knowledge or time. Pharmacists are well-positioned to overcome these challenges and facilitate deprescribing of these medications.

We sought to evaluate interventions utilizing pharmacists to deprescribe opioids and BZDs in older adults.

We conducted a rapid review following a comprehensive literature search to identify interventions with pharmacist involvement for deprescribing opioids and BZDs in older adults. Studies were included based on: (1) inclusion of patients ≥ 65 years old receiving BZDs and/or opioids, (2) evaluation of feasibility or outcomes following deprescribing (3) pharmacists as part of the intervention. We included randomized, observational, cohort, and pilot studies. Studies that did not report specific results for BZD or opioids were excluded.

We screened 687 abstracts and included 17 studies. Most (n = 13) focused on BZD deprescribing. Few studies focused on opioids (n = 2) or co-prescribing of opioids and BZDs (n = 2). The most common intervention was educational brochures (n = 8), majority being the EMPOWER brochure for deprescribing BZDs. Other interventions included chart review with electronic notes (n = 4), pharmacist-led programs/services (n = 2), and multifactorial interventions (n = 3). Many studies were underpowered or lacked suitable control groups. Generally speaking, interventions utilizing educational materials and those in which pharmacists engaged with patients and providers were more effective. Interventions relying on electronic communication by pharmacists were less successful, due to low acceptance or acknowledgement.

We identified a number of feasible interventions to reduce BZD use, but fewer interventions to reduce opioid use in older adults. An optimal approach for deprescribing likely requires pharmacists to engage directly with patients and providers. Larger well-designed studies are needed to evaluate the effectiveness of deprescribing interventions beyond feasibility.
