Health systems that work at the national level frequently fail at the community level. The last mile is where the system meets the person who needs it.
The Last Mile Problem
The last mile in health delivery is the gap between the health system's formal capacity — its facilities, its health workers, its medicines and equipment — and the ability of the specific person who needs care to actually access and receive it. This gap is present in every health system to some degree and is largest in the systems that serve the most geographically dispersed, economically marginalised, and socially excluded populations. The hospital technically accessible to everyone within fifty kilometres provides little practical access to the person who cannot afford transportation, who cannot leave their work, or whose cultural background makes engagement with the formal health system uncomfortable.
The Last Mile Investment
Closing the last mile requires investment in the community-level health infrastructure that connects the formal health system to the populations it serves: the community health workers who provide the trusted relationship that formal health workers cannot, the mobile clinics that bring services to communities that cannot access fixed facilities, and the community health information systems that track which people are receiving care and which are not. These investments are structurally less politically salient than hospital construction and equipment procurement — they serve the populations with the least political power — but they produce larger health impact per unit of investment in the contexts where the last mile gap is largest.
The last mile is where health systems earn their legitimacy or lose it. The system that functions at the national level and fails at the community level has not built a health system — it has built a health resource that a fraction of the population can access.
