The Basics
Health Systems - Research Needs
The World Health Organization (WHO) defines health systems as, “all the activities whose primary purpose is to promote, restore, or maintain health.” Health systems strengthening aims to improve health by responding to people’s needs and providing services in a fair and equitable manner.1 The WHO defined six building blocks of health systems that encompass the activities needed to provide universal access to needed services and universal coverage of health care through comprehensive strategies. The scope of activities ranges from high-level governance issues to community level point-of-care and service delivery approaches.
Why Research on Health Systems?

Weak or missing elements of the building blocks create bottlenecks to efficient and effective delivery of health care. Health systems research identifies where bottlenecks exist and provides innovative solutions to improve the delivery of care. For example, health workers need information, tools, skills and medicines to effectively deliver health care services; patients need money, subsidies or insurance to utilize them. Practitioners and program implementers face numerous challenges in providing care and delivering interventions at all levels of health systems, but particularly at the community level. Both the need and the capacity for finding solutions are greater than ever before. Researchers, working in partnership with governments and the private sector, play an important role in developing and sustaining health systems and providing feasible solutions to systemic bottlenecks. Confronting these challenges in settings where health infrastructures are crumbling and weaknesses exist on multiple fronts requires targeted research on health systems and health policy.2 Coordination and collaboration on research projects are needed to avoid duplication, maximize opportunities for data collection and comparison, and to build local capacity for health systems research in developing countries, where obstacles to care are especially problematic.
Research Priorities for the Building Blocks2 ◗
Governance, Leadership and Management. Identify factors that contribute to the success and failure of programs or financing mechanisms. § § §
◗
On a national level, develop health priorities to guide investment and research. Promote the development of supportive policies; encourage consideration of ethical matters.3 At the hospital and clinic levels, examine successful interventions for management and leadership.
Financing Health Care and Health Systems. Monitor long-term results of innovative financing mechanisms for health, such as the effectiveness of national health accounts, national health insurance policies or community-based financing schemes to cover those who cannot pay out of pocket.4, 5 Identify the costs associated with building a health system; determine what an investment in health systems strengthening will buy; examine the returns on investment for different disease-specific initiatives in the context of stronger health systems. 6, 7 § §
Estimate the minimum system requirements, changes needed to make programs work, options for scaling up coverage, options to finance the scaling up coverage, and costs of implementing those changes. Determine the transparency, availability and accessibility of health systems financing data.
◗
Health Information Systems. Test ways to provide accurate, reliable health information in a sustainable manner. Useful health information systems and technology investments will facilitate the management of information in all aspects of the health system and will improve the capacity for surveillance and emergency response activities.
◗
Health Workforce. Research the distribution and tasks of doctors, nurses and community health workers; and research methods of evaluation, supervision, and the impact of workforce issues on quality of care. § §
Research system constraints faced by various health personnel and programs. Understand what motivates providers in different communities and resource-strained settings and what incentives might encourage better quality of care, such as pay-for-performance schemes.
◗
Medical Products and Technologies. Research to develop effective forecasting and distribution systems for drugs and other commodities to avoid shortages of essential medicines; research the causes of health workers being ill-equipped with drugs and supplies to deliver necessary care and explore and test the effectiveness of solutions.
◗
Service Delivery. Research to identify and disseminate findings about affordable, safe and effective interventions that are widely available and to make access to health care more equitable; compare the effectiveness of delivering services through disease-specific programs to delivery through primary care or integrated mechanisms. § §
Research is needed on how to deliver prevention, care and treatments in rural communities where there is limited infrastructure, particularly to tackles diseases of the poor. Engage communities in the design of delivery mechanisms in order to identify culturally appropriate, convenient and sustainable approaches and measure results.6
Operations research focuses on defining and measuring important process and outcome indicators that assess health systems, including service delivery successes and failures, and intervention and policy effectiveness. Include research that links health systems inputs to outcomes, including long- and short-term cost-savings and other outcome indicators. All research should address interrelated systems, including financing and workforce needs.
From Health Systems Research to Policy Action2 Further investigation is required to examine the impact of health systems on maternal and child mortality, access to reproductive health services and the incidence of infectious disease for Millennium Development Goals 4, 5, and 6. In addition, research is needed to establish the link and determine the impact of health systems strengthening on poverty reduction, gender equality, agricultural output and access to education, microfinance and clean water and sanitation.8 The dissemination of research results, both positive and negative, is critical to expanding the health system in an effective and efficient manner. Improvements in the flow of information to donors, policymakers and practitioners are needed to ensure that policy is evidence-based and to minimize the time it takes to transfer research to policy action.
A Call to Action The Global Health Council supports comprehensive prevention, care and treatment policies that are evidence-based and locally appropriate. The Council supports strategic investments in health systems that include research that identifies clear and measurable outcomes, effective interventions and the impact of disease-specific initiatives and achievement of the MDGs. The Council also calls for the United States, developing country governments and other public and private donors to continue their leadership role in strengthening health systems. 1
