- Abstract
Background: Central nervous system (CNS)-active polypharmacy (defined as concurrent exposure to three or more antidepressant, antipsychotic, antiseizure, benzodiazepine, opioid, or nonbenzodiazepine benzodiazepine receptor agonists) is associated with significant potential harms in persons living with dementia (PLWD).We conducted a pilot trial to assess a patient nudge intervention's implementation feasibility and preliminary effectiveness to prompt deprescribing conversations between PLWD experiencing CNS-active polypharmacy and their primary care clinicians ("clinicians")., Methods: We used the electronic health record to identify PLWD prescribed CNS-active polypharmacy in primary care clinics from two health systems. Clinics were assigned to intervention (n = 10) or control (n = 12), with PLWD in intervention clinics mailed an educational brochure to prompt discussion with clinicians about the appropriateness of their CNS-active regimen. We conducted chart reviews for evidence of documentation related to these medications and used the electronic health record (EHR) to assess preliminary effectiveness 120 days after sending the brochure (e.g., number of CNS-active medications prescribed, change in total standardized daily dose [TSDD] of CNS-active medications, and change in prevalence of CNS-active polypharmacy). We interviewed 10 clinicians from intervention clinics to assess their perceptions about the acceptability of the intervention., Results: PLWD in the intervention group (n = 61) and control group (n = 68) had an average age of 72.4 years (standard deviation [SD] 9.7), 62.8% were female, and 84.5% were white. We did not find any documented evidence of conversations related to CNS-active medications between PLWD who received the brochure and their primary care clinicians. After 120 days, there was no significant between-group difference in the mean number of CNS-active medications prescribed (- 1.0 [SD 1.3] versus - 1.0 [SD 1.3]), mean TSDD (- 1.6 [SD 6.0] versus - 1.3 [SD 5.8]), or the percentage of patients with CNS-active polypharmacy (52.6% versus 50.4%). Interviews with clinicians suggested they were aware that combinations of CNS-active medications were not ideal; however, they reported inheriting patients who were already on these medications, and they did not have sufficient clinic time or access to safer alternatives to overcome patient hesitation to deprescribe., Conclusions: A direct-to-patient mailed educational brochure did not demonstrate feasibility in provoking deprescribing conversations between PLWD and clinicians or preliminary effectiveness in decreasing CNS-active polypharmacy., Competing Interests: Declarations.
