A strategy developed by Canadian researchers for encouraging older patients with insomnia to wean themselves from sleeping pills and improve their sleep through behavioral techniques is effective, data suggest. If proven helpful for the millions of older Canadians who currently rely on nightly benzodiazepines (BZDs) and non-BZDs (colloquially known as Z drugs) for their sleep, it might yield an additional benefit: Reducing resource utilization.
“We know that cognitive behavioral therapy for insomnia (CBTI) works. It’s recommended as first-line therapy because it works,” study author David Gardner, PharmD, professor of psychiatry at Dalhousie University in Halifax, Nova Scotia, Canada, told this news organization.
“We’re sharing information about sleeping pills, information that has been embedded with behavior-change techniques that lead people to second-guess or rethink their long-term use of sedative hypnotics and then bring that information to their provider or pharmacist to discuss it,” he said.
The results were published in JAMA Psychiatry.
Better Sleep, Fewer Pills
Dr. Gardner and his team created a direct-to-patient, patient-directed, multicomponent knowledge mobilization intervention called Sleepwell. It incorporates best practice– and guideline-based evidence and multiple behavioral change techniques with content and graphics. Dr. Gardner emphasized that it represents a directional shift in care that alleviates providers’ burden without removing it entirely.
To test the intervention’s effectiveness, Dr. Gardner and his team chose New Brunswick as a location for a 6-month, three-arm, open-label, randomized controlled trial; the province has one of the highest rates of sedative use and an older adult population that is vulnerable to the serious side effects of these drugs (eg, cognitive impairment, falls, and frailty). The study was called Your Answers When Needing Sleep in New Brunswick (YAWNS NB).
Eligible participants were aged ≥ 65 years, lived in the community, and had taken benzodiazepine receptor agonists (BZRAs) for ≥ 3 nights per week for 3 or more months. Participants were randomly assigned to a control group or one of the two intervention groups. The YAWNS-1 intervention group (n = 195) received a mailed package containing a cover letter, a booklet outlining how to stop sleeping pills, a booklet on how to “get your sleep back,” and a companion website. The YAWNS-2 group (n = 193) received updated versions of the booklets used in a prior trial. The control group (n = 192) was assigned treatment as usual (TAU).
A greater proportion of YAWNS-1 participants discontinued BZRAs at 6 months (26.2%) and had dose reductions (20.4%), compared with YAWNS-2 participants (20.3% and 14.4%, respectively) and TAU participants (7.5% and 12.8%, respectively). The corresponding numbers needed to mail to achieve an additional discontinuation was 5.3 YAWNS-1 packages and 7.8 YAWNS-2 packages.
At 6 months, BZRA cessation was sustained a mean 13.6 weeks for YAWNS-1, 14.3 weeks for YAWNS-2, and 16.9 weeks for TAU.
Sleep measures also improved with YAWNS-1, compared with YAWNs-2 and TAU. Sleep onset latency was reduced by 26.1 minutes among YAWNS-1 participants, compared with YAWNS-2 (P < .001), and by 27.7 minutes, compared with TAU (P < .001). Wake after sleep onset increased by 4.1 minutes in YAWNS-1, 11.1 minutes in YAWNS-2, and 7.5 minutes in TAU.
Although all participants underwent rigorous assessment before inclusion, less than half of participants receiving either intervention (36% in YAWNS-1 and 43% in YAWNS-2) contacted their provider or pharmacist to discuss BZD dose reductions. This finding may have resulted partly from limited access because of the COVID-19 pandemic, according to the authors.
