Document the scale and consequences of primary health care system failure in low-income and middle-income countries, with particular focus on the structural financing and workforce gaps that drive the crisis.

Analysis of WHO Service Availability and Readiness Assessment (SARA) data across 120 countries, cross-referenced with World Bank health expenditure tracking and the 2024 Lancet Commission on Primary Healthcare. Coverage analysis of vaccination, maternal health, and basic disease treatment services. Workforce capacity assessment using Ministry of Health staffing data.

2 billion people globally lack access to basic primary health care — defined as coverage of essential services including vaccinations, maternal health, treatment of acute infections, and management of chronic disease. In Sub-Saharan Africa, 47% of districts do not have a single functional primary health center.

The average LMIC spends $34/capita annually on health; high-income countries spend $5,000+. A shortage of 18 million health workers globally, concentrated in low-income countries, means that many clinics exist but have no staff.

The consequences are catastrophic: maternal mortality in LMICs is 150x higher than in high-income countries; childhood diarrhea — entirely preventable — kills 600,000 children annually; diabetes and hypertension go undiagnosed and untreated, leading to preventable heart attacks and strokes.
