A cluster-randomized controlled trial to evaluate the effects of a simplified cardiovascular management program in Tibet, China and Haryana, India: study design and rationale
Background In re source -poor areas of China and India , the cardiovascular disease burden is high , but availability of and access to quality healthcare is limited . Establishing a management scheme that utilizes the local infrastructure and builds healthcare capacity is essential for cardiovascular disease prevention and management . The study aims to develop , implement , and evaluate the feasibility and effectiveness of a simplified , evidence -based cardiovascular management program delivered by community healthcare workers in re source -constrained areas in Tibet , China and Haryana , India . Methods / design This yearlong cluster-r and omized controlled trial will be conducted in 20 villages in Tibet and 20 villages in Haryana . R and omization of villages to usual care or intervention will be stratified by country . High cardiovascular disease risk individuals ( aged 40 years or older , history of heart disease , stroke , diabetes , or measured systolic blood pressure of 160 mmHg or higher ) will be screened at baseline . Community health workers in the intervention villages will be trained to manage and follow up high-risk patients on a monthly basis following a simplified ‘ 2 + 2 ’ intervention model involving two lifestyle recommendations and the appropriate prescription of two medications . A customized electronic decision support system based on the intervention strategy will be developed to assist the community health workers with patient management . Baseline and follow-up surveys will be conducted in a st and ardized fashion in all villages . The primary outcome will be the net difference between-group in the proportion of high-risk patients taking antihypertensive medication pre- and post-intervention . Secondary outcomes will include the proportion of patients taking aspirin and changes in blood pressure . Process and economic evaluations will also be conducted . Discussion To our knowledge , this will be the first study to evaluate the effect of a simplified management program delivered by community health workers with the help of electronic decision support system on improving the health of high cardiovascular disease risk patients . If effective , this intervention strategy can serve as a model that can be implemented , where applicable , in rural China , India , and other re source -constrained areas .Trial registration The trial was registered in the clinical trials.gov data base on 30 December , 2011 and the registration number is NCT01503814
