According to the Alma-Ata Declaration (1978), which of the following is the most common barrier to achieving universal health coverage through primary health care in low-income countries?

Explanation

## Understanding Universal Health Coverage Barriers in PHC **Key Point:** The Alma-Ata Declaration (1978) identified inadequate financial resources and weak health system infrastructure as the PRIMARY and most common obstacle to achieving universal health coverage through primary health care, especially in low-income and middle-income countries. ### Why This Barrier Is Most Common 1. **Financial Constraint** — Most low-income countries allocate <5% of GDP to health; PHC requires sustained funding for: - Basic health centres and sub-centres - Training and retention of health workers - Essential medicines and diagnostics - Immunization and maternal-child health programmes 2. **Infrastructure Deficit** — Lack of: - Road connectivity to remote areas - Electricity and water supply in health facilities - Cold chain for vaccines - Diagnostic equipment (blood pressure monitors, thermometers, basic labs) **High-Yield:** In India's context, despite the National Health Mission (NHM) and NRHM initiatives, resource scarcity remains the bottleneck — many sub-centres operate with inadequate staff, medicines, and equipment, directly limiting PHC delivery. ### Comparative Framework | Barrier | Frequency | Impact on PHC | Reversibility | |---------|-----------|---------------|---------------| | Financial/Infrastructure | Very high | Prevents service delivery | Slow (requires sustained investment) | | Tertiary care bias | High | Diverts resources | Medium (policy reorientation) | | Community participation gaps | High | Reduces uptake | Medium (health education) | | Traditional medicine reliance | Variable | Context-dependent | Low (cultural integration needed) | **Clinical Pearl:** Countries like Rwanda and Bangladesh have shown that even with limited resources, strategic PHC investment (community health workers, basic preventive services) yields high ROI in reducing maternal mortality and infectious disease burden.
