Results Of The Nashville Barber-pharmacist Hypertension Management Pilot Study

Background: The Los Angeles Barbershop Blood Pressure Study (LABBPS) demonstrated that collaboration between barbers and pharmacists delivering hypertension management could significantly improve blood pressure as well as access to care. It is unknown if this model can be translated to other locations. This single-arm, proof-of-concept pilot study tested the development and implementation of a similar protocol in Nashville, TN (NCT04232124). Methods: Between 2019 and 2021, community stakeholders, clinicians, investigators, and the LABBPS team convened to adapt the study design and protocol. Established barbershops with barbers willing to be trained on study procedures were recruited as study sites. Non-Hispanic Black male clients, aged 35-79 years with systolic blood pressure (SBP) > 140 mmHg on two screening days were eligible for participation. Enrolled participants met with a pharmacist for lifestyle and medication management at least once monthly for a six-month period. Barbers measured blood pressure during haircuts for additional monitoring. Results: Eight barbershops in business for an average of 20 (± 5) years participated in the trial. Barbers from each shop (range: 1-4) were trained. A total of 419 clients completed screening visit 1, 82 were eligible and 52 (12%) completed visit 2. We enrolled 36, with 30 completing the initial clinical visit and 27 had complete data at 6-months. Participants were on average age 50 (± 10) years, had a body mass index 33 (± 6), 44% were currently smoking, 52% with high school or less education, and 56% reported current primary care. Baseline BP 157.7±17.1/ 95.1±13.9 mmHg improved to 125.7±11.9/75.6±9.5, a change of -32.1±21.6/ -19.5±14.1, respectively. At 6-months 85% of the group had a BP<140/90, 74% BP<135/85, and 67% BP<130/80. At baseline 15% of participants reported health as excellent/very good and this increased to 56% at 6-months (p=0.002). Adverse reactions reported were minimal. Conclusion: Implementation of the barber-pharmacist model of hypertension management and care delivery improved BP control among hypertensive Black men in Nashville. Lessons learned regarding adaptation overcoming unforeseen barriers will inform expansion into additional naïve locations for future research.
