Historically, the US has been the largest contributor to development assistance for health (DAH), although its allocation has shifted in response to outside forces. This included, for example, the establishment of the Millennium Development Goals (MDGs) in 2000, which emphasised child mortality, maternal health, HIV/AIDS, and malaria. This led to funds being earmarked for disease-specific interventions rather than health system strengthening (HSS). In 2007, the World Health Organization (WHO) published six health system building blocks, representing essential components of strong health systems. In 2015, the MDGs were replaced by the Sustainable Development Goals (SDGs), which emphasised capacity-building as opposed to specific health problems. The Lancet Commission on Global Surgery, meanwhile, highlighted surgical capacity building as essential to achieving Universal Health Coverage (UHC). Given the renewed emphasis on a comprehensive approach rather than disease-specific interventions, one might anticipate the US aligning with this rhetoric in its allocation of DAH. However, we hypothesise that this is not the case. We queried the Organization for Economic Co-operation and Development (OECD) database for allocation of US DAH to low- and middle-income countries between 1995 and 2019, thereby excluding data after 2019 to avoid the influence of the coronavirus disease 2019 pandemic. OECD entries were assigned to health systems strengthening (HSS) or disease-specific interventions categories. The WHO building blocks were used as a framework for health systems strengthening. From 1995 to 1999, US DAH allocated to HSS decreased from 42% to 34%. The allocation decreased further from 34% in 2000 to 4% in 2007; correspondingly, DAH allocated to disease-specific interventions increased from 67% to 96%. Between 2008 and 2019, the distribution of US DAH remained relatively stable, with funds allocated to HSS versus disease-specific interventions ranging from 3-12% and 88-98% respectively. While total US DAH contributions in the 1990s and early 2000s were significantly lower compared to the decade that followed, the distribution of these funds was more evenly divided between HSS and disease-specific interventions. Despite attempts by the WHO and United Nations to redirect attention to HSS as the path to achieving UHC, the US continues to largely support disease-specific interventions and overlook the importance of HSS, including surgical capacity building.
