To date, the precise components needed for effective HTN self-management programs have yet to be defined, and access to multicomponent targeted support for HTN management that include telemonitoring remain inaccessible and costly. Objective: The aim of this pilot study was to evaluate the impact of a digital HTN self-management program on blood pressure (BP) control among adults with excess body weight. Methods: A single-arm, nonrandomized trial was performed to evaluate a digital HTN self-management program that combines comprehensive lifestyle counseling with HTN education, guided HMBP, support for taking medications, and led by either a registered nurse or certified diabetes care and education specialist. A sample of 151 participants were recruited using a web-based research platform (Achievement Studies, Evidation Health Inc). The primary outcome was change in systolic BP from baseline to 3 months, and secondary outcomes included change in diastolic BP and medication adherence. Results: Participants’ mean age was 44.0 (SD 9.3) years and mean BP was 139/85 mm Hg. At follow-up, systolic and diastolic BP decreased by 7 mm Hg (P<.001, 95% CI –9.3 to –4.7) and 4.7 mm Hg (P<.001, 95% CI –6.3 to –3.2), respectively. Participants who started with baseline BP at goal remained at goal. For participants with stage 1 HTN, systolic and diastolic BP decreased by 3.6 mm Hg (P=.09, 95% CI –7.8 to 0.6) and 2.5 mm Hg (P=.03, 95% CI –4.9 to –0.3). Systolic and diastolic BP decreased by 10.3 mm Hg (P<.001, 95% CI –13.4 to –7.1) and 6.5 mm Hg (P<.001, 95% CI –8.6 to –4.4), respectively, for participants with stage 2 HTN. Medication adherence significantly improved (P=.02). Conclusions: This pilot study provides initial evidence that a digital HTN self-management program improves BP and medication adherence.
