Table 1. Hierarchy of Price Sources .

Criteria	Rationale
Is the price recent?	Up to date prices account for changes in inflation and are more relevant to the decision problem.
Is the source of price a public source?	This costing exercise uses a provider perspective for the public sector. The prices for inputs purchased by the public sector such as medicines and equipment can often differ substantially from private sector prices. We therefore attempted to use the purchase prices for public sector providers.
Is the source nationally representative?	At this stage, the UHC benefit package and its unit costs are a national exercise therefore the price sources used were ranked higher if they were nationally representative.

Abbreviation: UHC, universal health coverage.
