Brief summary
Hypertension is a global risk factor for cardiovascular diseases. Approximately 80% hypertension burden is in low-and-middle income countries. Hypertension can be managed with antihypertensive medication and following effective lifestyle interventions, however the control rate of hypertension among those on treatment is dismal. In Nepal, a quarter of adult population have hypertension of whom, 44% are unaware of their status, 33% are on treatment, and, only 12% are controlled. A comprehensive intervention strategy for hypertension management has shown promising results in high income countries. Therefore, it is of interest to understand its effectiveness, appropriateness and feasibility in the low income settings such as Nepal. The objective of the trial is to assess the impact on net change in mean systolic blood pressure measured between 7 to 8 months follow-up of a comprehensive intervention which provides personalized counselling on lifestyle modification and medication adherence together with support for regular monitoring of blood pressure at home, compared with a control arm where hypertensive patients have access to routine care only. The investigators are proposing a cluster randomized controlled trial conducted in government health facilities from Budhanilakantha, an urban municipality in the Bagmati Province of Nepal. Trial arms: 1) control (routine hypertension care); 2) Comprehensive approach to hypertension management that includes blood pressure (BP) audit and feedback by physician (nurse and doctor), and patient support to monitor BP, and home based patient care by community health workers to encourage self-monitoring of BP followed by tailored educational counselling on behavioral and lifestyle change. Eligible participants providing consent will be enrolled into the trial by a research assistant who will conduct interviews. Those from the intervention arm will receive the home visits for 6 months. Participants from both arms will provide follow up data in 7 to 8 months.
Interventions
BEHAVIORALComprehensive approach to hypertension management
Trained health workers will review blood pressure (BP) logs and provide treatment. The patients will receive a BP lowering informational package, BP monitoring device and log book and pill-box and medication table. The participants will receive monthly home visits (6 visits) to discuss hypertension and ways to manage it. They will be encouraged to identify problems and developing an action plan to solve them. The participants will be encouraged to set behavioral goals. The follow up visits will review the progress made in implementing action plan and goals set and updating them. Review BP logs and facilitate tailored discussion on topics based on problems faced by participants on barriers to medication adherence, physical activity, weight management or diet. The family members will be involved and be accountable in supporting the patients in achieving the action plans.
