An intervention by community pharmacists consisting of sending elderly patients educational information on deprescribing of inappropriate medications resulted in higher levels of discontinuation of inappropriate medications within 6 months compared with in patients who received usual care, according to a study published in JAMA.

Inappropriate prescriptions to older individuals can lead to higher hospitalization rates and adverse events, and remain a concern. A collaborative effort among patients, physicians, and pharmacists to optimize medication management with the aid of communication regarding potential harm and safer alternatives may help mitigate these concerns.

The Developing Pharmacist-Led Research to Educate and Sensitize Community Residents to the Inappropriate Prescriptions Burden in the Elderly (D-PRESCRIBE) study ( identifier: NCT02053194) was a 2-group cluster randomized multiblinded trial conducted in Quebec, Canada, between February 2014 and September 2017.

A total of 69 community pharmacies were randomly assigned to provide an intervention (n=34) or usual care (control; n=35). The intervention consisted of providing patients ≥65 years who were prescribed 1 of 4 Beers Criteria medications (ie, sedative-hypnotics, first-generation antihistamines, glyburide, or nonsteroidal anti-inflammatory drugs [NSAIDs]) deprescribing information (n=248; 61.7% women) or usual care (n=241; 70.1% women). Study participants were followed for 6 months.

Intervention group pharmacists provided patients a deprescribing brochure and sent their physicians a pharmaceutical opinion letter advocating for deprescribing inappropriate medications. Usual care pharmacists offered conventional care without educational intervention. The primary outcome was inappropriate medication discontinuation at the 6 month-follow-up.

Of 489 enrolled patients (mean age, 75 years; 66% women; 23% aged ≥80 years), 437 individuals (89%) completed the study (n=219 [88%] received intervention; n=218 [91%] received usual care). After 6 months, inappropriate medications were discontinued by 106 patients (42.7%) who had received the intervention and by 29 patients (12.0%) who had received usual care (risk difference, 31%; 95% CI, 23%-38%; number needed to treat [NNT], 3.22; relative risk [RR], 3.55).

Sedative-hypnotic drugs were stopped by 63 (43.2%) of 146 patients in the intervention group compared with 14 (9.0%) of 155 patients in the control group (risk difference, 34%; 95% CI, 25%-43%; NNT, 2.94; RR, 4.78). For glyburide, 30.6% vs 13.8% of patients, respectively, had discontinued the medication (risk difference, 17%; 95% CI 2%-31%; NNT, 5.88; RR, 2.22). NSAIDs were discontinued by 57.6% vs 21.7% of patients in the intervention and control groups, respectively (risk difference, 35%; 95% CI 10%-55%; NNT, 2.86; RR, 2.64). The P value for the interaction was .09. Antihistamines were not analyzed because of a small sample size (n=12).

A total of 37 patients who discontinued an inappropriate medication replaced it with another drug. Of participants taking sedative-hypnotic drugs, 38% who tried tapering reported experiencing withdrawal symptoms. No serious adverse events that required hospitalization were reported.

Study limitations include a lack of information regarding extra clinic visits or telephone contacts, limited follow-up time, and uncertainty regarding additional factors that may have contributed to drug cessation.

“A pharmacist-led intervention has the potential to reduce prescriptions for inappropriate medication in older adults,” concluded the authors.
