The membership of the GACD has expanded from the original six health and medical research funding organizations in 2009 to its current 12 member agencies. The founding GACD funding member agencies in 2009 were the Canadian Institutes of Health Research (CIHR), Australia's National Health and Medical Research Council (NHM), the US National Institutes of Health, the United Kingdom Medical Research Council (MRC), the South African Medical Research Council (MRC), and the Indian Council of Medical Research (ICMR). Its overarching goals are three-fold: coordination among member funding agencies, collaboration across research teams, and communication with policymakers. Funding agencies have been encouraged by the success of the GACD collaboration model, resulting in new members and funding for each research program. In 2014, member agencies committed over $30 million US dollars to the GACD Diabetes Program, which consists of 17 projects around the world, and a GACD Lung Diseases Program is being initiated in 2016. Hypertension was chosen by GACD as its inaugural funding priority in 2010, resulting in the GACD Hypertension Program with a total of $23 million US dollars in committed funds for 15 studies of up to 5 years’ duration. Coordinating peer-reviewed funds within this program from both developed and developing countries, the GACD has demonstrated the viability of this new approach to funding research and the ability to coordinate international efforts in the prevention and control of NCDs. Isolated studies are limited in their ability to generate scalable evidence for tackling complex issues. The extensive interaction and exchange of information among GACD network researchers has unlocked great potential to generate new evidence to influence policy and practice and to build research capacity in LMICs. A central tenet of the GACD has been the emphasis on using the latest implementation science approaches, and pairing high- and low-income country partners. Interventions are carefully culturally tailored to LMIC study settings, populations, and contexts as well as designed to engage local and national policymakers at all stages of project development, implementation, and evaluation. The aims and objectives of the Hypertension Program are summarized in the Table. The researchers for each program are listed in the Appendix. The GACD Hypertension Program includes a network of researchers from 19 countries. Six projects are being undertaken in Africa (Ghana, Kenya, Nigeria, Rwanda, South Africa, Tanzania, and Uganda), three in South Asian countries, and three in a number of locations within India and are working in a number of different locations throughout that country. There is also a project being conducted in the Pacific Islands of Fiji and Samoa, as well as three projects in South America (Argentina, Colombia, and Peru), one in aboriginal communities in Canada, and one in China and in Malaysia. In all, more than 100,000 participants are being surveyed and screened with an overall goal to recruit more than 25,000 patients with hypertension into various trials of preventive and/or clinical interventions. The majority of projects (13 in total) are randomized pragmatic clinical trials. Other projects involve population-based surveys and a preintervention and postintervention population assessment. Standardized definitions for hypertension are being used (blood pressure ≥140/90 mm Hg or being treated for hypertension), with two studies also including a lower threshold (≥130/80 mm Hg) for people with diabetes. One study in China involves primary school children and their families; the remainder of the studies are enrolling only adults (18 years and older). The studies are a combination of pragmatic effectiveness and/or proof-of-concept trials involving heterogeneous study populations, hence the focus on maximizing external validity to maintain the generalizability of study findings. Secondary studies include barriers and facilitators to the provision of care, as well as studies of supporting policies and regulatory frameworks. Each study has identified innovative intervention strategies including the use of short message service (SMS) text messaging, “smart phone” technologies, child-to-adult education for sodium reduction, policy interventions, and task-shifting. Task-shifting includes the rational redistribution of tasks among the health workforce to make more efficient use of human resources. In addition, most projects emphasize sustainability, ongoing knowledge engagement with relevant local stakeholders and end-users, and the potential for future implementation and scale-up. The research principles and overall aims of the GACD Hypertension Program have been shaped to address the needs of the local context and to generate lessons, approaches, and results that can be more widely implemented and generalized to other settings and contexts. Through the annual scientific meeting, the research teams have developed into a global research community, in turn strengthening the individual research projects. Several researcher-initiated, cross-project working groups on different topics have been established to facilitate the opportunities to regularly exchange and interact. The Annual Scientific Meetings (ASM) hosted by different GACD member agencies are convened to facilitate the learnings and joint activities of all teams. This includes capacity development workshops on implementation science. Development of a core set of consensus measures across the program will enable cross-site data analysis and comparisons in line with the implementation research agenda of the GACD.5 These studies fit in with the WHO's Global Monitoring Framework for NCDs for blood pressure control and dietary sodium reduction. Through a researcher-initiated, process evaluation working group, each team is being encouraged to conduct and publish a process evaluation in order to facilitate wider implementation and appropriate adaptation and refinement of programs in the future. In conclusion, the GACD Hypertension Program is undertaking important research to improve hypertension awareness, prevention, treatment, and control, and to maintain normal blood pressure levels in healthy people at risk for hypertension in vulnerable populations around the world. In the coming years, the findings from these studies will help policymakers and healthcare payers to better manage the emerging global NCD epidemic. Hopefully, this new approach will facilitate the development of cost-effective, evidence-based guidelines and policies leading to the control of hypertension in LMICs, which bear the largest burden of hypertension and its complications globally.
