Item Cluster randomized trial on integrated primary care strategies to reduce high blood pressure in rural communities in Sri Lanka: Report from the feasibility study(Sri Lanka Medical Association, 2016) de Silva, H.A.; Kasturiratne, A.; Luke, W.A.N.V.; Ediriweera, D.S.INTRODUCTION: Hypertension is the leading cause of mortality worldwide. Control of Blood Pressure and Risk Attenuation (COBRA) trial conducted in Pakistan, demonstrated that the combined intervention of home health education (HHE) plus training general practitioners (GPs)was more effective for lowering blood pressure (BP) compared to usual care. OBJECTIVES: A feasibility study was conducted to adapt and integrate evidence-based strategies to control hypertension in the primary healthcare system in rural Sri Lanka. METHOD: Public Health Midwives (PHMs) in three Medical Officer of Health areas in Kurunegala district were trained on digital BP measurement and health education of hypertensive patients and their families PHMs screened household members above 40 years of age to identify individuals with hypertension. Socio-demographic data was collected and HHE was delivered as per training manual.PHMs referred probable patients to trained medical officers in the closest divisional hospital for further care and regular follow up. A referral loop was maintained by tracking the referred patients at the rural hospital by supervising PHM and medical officers. RESULTS: 142 hypertensive individuals were recruited and 129(90.8%) of them presented to the health care facility for follow up. At the end of follow up mean systolic blood pressure reduction of 13.8 mmHg (p-0.001) in those with poorly controlled BP (SBP≥160or DBP≥100 ) was demonstrated. CONCLUSIONS: It is feasible to implement this community-based strategy integrated to routine care for improving the management of hypertension in rural communities. Findings of this feasibility study will be fully evaluated in a large randomized controlled trial.Item Multicomponent intervention versus usual care for management of hypertension in rural Bangladesh, Pakistan and Sri Lanka: study protocol for a cluster randomized controlled trial(BioMed Central, 2017) Jafar, T.H.; Jehan, I.; de Silva, H.A.; Naheed, A.; Gandhi, M.; Assam, P.; Finkelstein, E.A.; Quigley, H.L.; Bilger, M.; Khan, A.H.; Clemens, J.D.; Ebrahim, S.; Turner, E.L.; Kasturiratne, A.; for COBRA-BPS Study GroupBACKGROUND: High blood pressure (BP) is the leading attributable risk for cardiovascular disease (CVD). In rural South Asia, hypertension continues to be a significant public health issue with sub-optimal BP control rates. The goal of the trial is to compare a multicomponent intervention (MCI) to usual care to evaluate the effectiveness and cost-effectiveness of the MCI for lowering BP among adults with hypertension in rural communities in Bangladesh, Pakistan and Sri Lanka. METHODS/DESIGN: This study is a stratified, cluster randomized controlled trial with a qualitative component for evaluation of processes and stakeholder feedback. The MCI has five components: (1) home health education by government community health workers (CHWs), (2) BP monitoring and stepped-up referral to a trained general practitioner using a checklist, (3) training public and private providers in management of hypertension and using a checklist, (4) designating hypertension triage counter and hypertension care coordinators in government clinics and (5) a financing model to compensate for additional health services and provide subsidies to low income individuals with poorly controlled hypertension. Usual care will comprise existing services in the community without any additional training. The trial will be conducted on 2550 individuals aged ≥40 years with hypertension (with systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg, based on the mean of the last two of three measurements from two separate days, or on antihypertensive therapy) in 30 rural communities in Bangladesh, Pakistan and Sri Lanka. The primary outcome is change in systolic BP from baseline to follow-up at 24 months post-randomization. The incremental cost of MCI per CVD disability-adjusted life years averted will be computed. Stakeholders including policy makers, provincial- and district-level coordinators of relevant programmes, physicians, CHWs, key community leaders, hypertensive individuals and family members in the identified clusters will be interviewed. DISCUSSION: The study will provide evidence of the effectiveness and cost-effectiveness of MCI strategies for BP control compared to usual care in the rural public health infrastructure in South Asian countries. If shown to be successful, MCI may be a long-term sustainable strategy for tackling the rising rates of CVD in low resourced countries.
