Regional Network for Equity in Health in east and southern Africa (EQUINET): Disussion Paper 111<br> The health services delivery system in Zambia is pyramid in structure, with primary healthcare (PHC) services at community level, at the base, followed by first and second level hospitals at district and provincial levels, respectively, and third level (tertiary) services at national level. Notably, primary health services are free in Zambia and health service providers are either governmentowned or not-for-profit facilities. <br> Over the years, resource constraints have affected the quality and extent of healthcare services at all levels, requiring the mobilisation of additional resources for the sector. In doing so, prioritisation was high on the agenda of health sector reform. The EHB, therefore, prioritises interventions with the highest impact on the population, enabling policy makers to revisit priority diseases and conditions and to cost the services provided at each level of facility. Other key issues in developing the EHB in Zambia have included the need to have cost-effective services and cost per capita of services for more systematic budgeting, to rank interventions and to validate and cost the health benefit package as a whole.
