A standardized ingredients approach was used to measure the costs of CS. This approach
requires information on the quantities of the physical inputs needed and on their unit costs.
Only the marginal resources directly associated with the C-section procedure were costed; in
other words, none of the routine costs associated with antenatal care visits were included, nor
were other services that would be considered part of normal vaginal delivery (such as the costs
of skilled birth attendants, tetanus prophylaxis or clean cord practices).
