Abstract

Objectives: The Hyperlink trial tested a 12-month intervention of home blood pressure (BP) telemonitoring with pharmacist case management in adults with uncontrolled hypertension. The intervention resulted in improved BP control compared with usual care at both 6 (72% vs. 45%; P < 0.001) and 12 months (71% vs. 53%; P = 0.005). We sought to investigate factors contributing to intervention success. Design: Mixed-methods analysis of process of care data, patient focus groups, and pharmacist interviews. Participants: Data from 228 intervention patients were examined from the original 450 patients randomly assigned from 16 primary care clinics. Five patient focus groups and 4 pharmacist interviews were conducted to ascertain the patient and pharmacist perspective. Focus group and interview data were coded, and themes relevant to pharmacists were identified. Outcome measures: Home BP readings of less than 135/85 mm Hg and patient focus group and pharmacist interview themes. Results: Mean BP at the intake visit was 148/85 mm Hg. Antihypertensive medications were adjusted in 10% of patients at the initial in-person visit, 33% at phone visit 1, 36% at phone visit 2, and 19% at phone visit 3. Thereafter, medication changes declined. The mean home BP for patients at the first phone visit was 136/80 mm Hg, 126/74 mm Hg at 3 months, and 123/73 mm Hg at 5 months, with little change thereafter. Key components of success from patient and pharmacist interviews included a strong patient–pharmacist relationship, individualized treatment plans, and frequent phone contact with the pharmacist. Conclusion: Frequent adjustments to the antihypertensive treatment regimen based on home BP telemonitoring resulted in rapid lowering of BP. Our results suggest that an intensive telephone-based intervention with the key components of medication adjustments, a strong patient and pharmacist relationship, and individualized treatment plans can achieve BP control in only 3 months in many patients with uncontrolled hypertension.
