Abstract

Background: Low-cost, automated interventions that increase knowledge and skills around diet and lifestyle modifications are recommended for cardiovascular disease risk reduction.

Methods: We initiated a quality improvement program to assess the impact of a web-based diet and lifestyle intervention utilizing short animated videos in adults with high blood pressure (BP) at a primary care clinic in Saudi Arabia. We enrolled adults with elevated BP, not on BP medications, who were identified using the electronic medical record. We delivered a web-linked diet and lifestyle intervention using animated videos covering diet and lifestyle topics. Videos and reminders were sent weekly for 5 weeks. Outcomes were proportion who engaged in the program, returned for a repeat BP within 3 months, and change in BP.

Results: We enrolled 269 adult participants, with a mean (SD) age of 41.6 (12.4) years; 77% were male. At the conclusion of the pilot, we demonstrated a high level of engagement: overall, 69% of materials were viewed and 67% of patients returned for BP. Patients who returned had a mean (SD) baseline systolic BP of 138.0 (7.2) mm Hg and a large mean reduction in systolic BP from baseline, -10.5 mm Hg (12.4; P < 0.001).

Conclusions: Overall, the feasibility of a video-assisted, web-based, diet and lifestyle intervention as a support tool for hypertension management demonstrated a high participation rate and a high return rate for reassessment of BP. These findings suggest that this low-cost, automated intervention may have a great potential as a scalable tool for blood pressure management. However, randomized trials to understanding the effectiveness of the support tools are needed.
