It’s another deprescribing super special on today's GeriPal Podcast, where we delve into the latest research on deprescribing medications prescribed to older adults. Today, we explore four fascinating studies highlighting innovative approaches to reducing medication use and improving patient outcomes.

In our first segment, we discuss a study led by Constance Fung and her team, which investigated the use of a masked tapering method combined with augmented cognitive behavioral therapy for insomnia (CBTI) to help patients discontinue benzodiazepines. The study involved 188 middle-aged and older adults who had been using medications like lorazepam, alprazolam, clonazepam, temazepam, and zolpidem for insomnia. The results were impressive: 73% of participants in the masked tapering plus augmented CBTI group successfully discontinued their medication, compared to 59% in the open taper plus standard CBTI group. This significant difference highlights the potential of targeting placebo effect mechanisms to enhance deprescribing efforts.

Next, we turn to Emily McDonald, the director of the Canadian Medication Appropriateness and Deprescribing Network, to discuss her study on the impact of direct-to-consumer educational brochures on gabapentin deprescribing. Patients received brochures detailing the risks of gabapentinoids, nonpharmacologic alternatives, and a proposed deprescribing regimen (see here for the brochure). Additionally, clinicians participated in monthly educational sessions. The intervention group saw a deprescribing rate of 21.1%, compared to 9.9% in the usual care group. This study underscores the power of patient education in promoting safer medication use.

In our third segment, we explore Amy Linsky’s study that examined the effect of patient-directed educational materials on clinician deprescribing of potentially low-benefit or high-risk medications, such as proton pump inhibitors, high-dose gabapentin, or risky diabetes medications. The intervention involved mailing medication-specific brochures to patients before their primary care appointments (click here for the brochure). The results showed a modest but significant increase in deprescribing rates among the intervention group. This approach demonstrates the potential of simple, low-cost interventions to improve medication safety.

Finally, we discuss Michelle Odden’s study, which used a target trial emulation approach to investigate the effects of deprescribing antihypertensive medications on cognitive function in nursing home residents. The study included 12,644 residents and found that deprescribing was associated with less cognitive decline, particularly among those with dementia4. These findings and the two studies Michelle mentions in the podcast (DANTE and OPTIMIZE) suggest that carefully reducing medication use in older adults may help preserve cognitive function. However, the DANTON study adds more questions to that conclusion.

Join us as we dive deeper into these studies and discuss the implications for clinical practice and patient care. Don’t miss this episode if you’re interested in the latest advancements in deprescribing research!
