Design, content and financing of an essential national package of health services.

A minimum package of public health and clinical interventions, which are highly cost-effective and deal with major sources of disease burden, could be provided in low-income countries for about US$ 12 per person per year, and in middle-income countries for about $22. Properly delivered, this package could eliminate 21% to 38% of the burden of premature mortality and disability in children under 15 years and 10-18% of the burden in adults. The cost would exceed what governments now spend on health in the poorest countries but would be easily affordable in middle-income countries. Governments should ensure that, at the least, poor populations have access to these services. Additional public expenditure should then go either to extending coverage to the non-poor or to expansion beyond the minimum collection of services to an essential national package of health care, including somewhat less cost-effective interventions against a larger number of diseases and conditions.
