Introduction
Global efforts to improve health, especially of women, newborns and children, require comprehensive and creative approaches. New global frameworks and calls to action (Every Woman Every Child, People-Centred Health Systems, United States Agency for International Development (USAID) Acting on the Call), all state the value of involving multiple stakeholders in health, including and especially ‘communities’.1–3 The UN’s Global Strategy, similar to other global guidance documents, labels community health work as an ‘essential component of health system resilience’ and community engagement as ‘one of the nine action areas’ required to improve health systems.4–6 The recent Global Conference on Primary Health Care (PHC), held in Astana, Kazakhstan, in 2018, renews past promises and principles of healthcare for all.7
Communities are groups of families, individuals and other types of networks and social circles that provide support and are often the unit on which health activities are organised and focused. Formal health services may be offered at health facilities, such as hospitals and health centres, but many services are provided at the community level, from familial provision of preventive or curative care in the household, to systematic clinical outreach from facilities. While most curative and specialised care should be provided in facility settings, many preventive, preliminary screening and basic treatments may be provided outside of formal facilities. Activities at the community level may also involve advocacy, education, governance, fundraising, inter-sectoral collaborations and other types of indirect support to the health system. Thus, community health has been recognised as foundational to global health, but is often treated in health systems frameworks as a forgotten and rediscovered issue or a secondary consideration.8–11
Health systems frameworks can serve many purposes, including: to describe the structure, organisation, functions and processes of a health system; to conceptualise actions to improve health system performance; or to coordinate and harmonise national and global health systems investment strategies, programme support and tools.12 It is impossible for one framework to serve all needs, as evidenced by the 41 different health systems strengthening frameworks developed from 1972 to 2011 identified in a recent review13 and the oft-quoted idea that ‘all models are wrong, but some are useful’.14 Health systems frameworks attempt to include the most salient aspects of a health system and the interlinked factors underpinning health system functionality and use. However, most of these frameworks exclude, or do not integrate ‘community health’ explicitly.15 Some frameworks include community elements under ‘context’ or ‘population’, but these are generally not operationally useful for planning and design purposes. Some recent recognition of the invisibility of community roles has occurred. For example, the Health Systems Global Research Symposium in 2018 listed a theme: “Community health systems—where community needs are located, but often the invisible level of health systems”.16 Global discourse around the Alma-Ata anniversary and 2018 meeting in Astana has brought yet again attention to the role of communities in providing PHC.7 In this paper, we propose simple but significant changes to a well-known health system framework as a guide or thinking tool for programmers, policymakers and donors of health systems efforts to more consciously include community health.
The WHO’s Health System Framework (also known as the ‘WHO building blocks’) has provided a common language and dominant structure of discourse on health systems issues in the last decade. Its utility, in spite of limitations, is commonly recognised by policymakers, programmers and scholars in global health.8 Although not the original intention of the framework, the WHO building blocks have become a tool for planning, funding decisions and establishing priorities. Its traditional six operational building blocks—service delivery, health workforce, information, medical products and technologies, financing, and leadership and governance—have become shorthand for describing health systems and for guiding investments in health systems strengthening.8 9 11 While ubiquitous, the framework is not without controversy.9 WHO itself has clarified how the framework provides a mapping of six essential groups of inputs required to support or strengthen health systems, but that it is also too static to help navigate the complexity of health systems.17 We fully endorse the evolving and growing school of thought for applying ‘systems thinking’ to the complexity of changes in health systems, but we aim to focus on the building blocks, and how they contribute to a disconnect—and a bias against community health—between health systems interventions and investments, at the policy level.9
