To efficiently allocate limited resources, National Tuberculosis Program (NTP) staff and technical assistance (TA) teams need to know the likely cost and health impact of available intervention packages. Intervention packages can be quantified by the resources they require to achieve a quantified health impact. This can be categorised into A) what resource needs are required for an intervention (e.g. the amount of nurse time and the number of diagnostics), B) the total cost of these resources (e.g. the unit cost multiplied by the resource amount), and C) the likely increase in health impact (e.g. an increase in treatment success) (see Figure).

As part of this aim, TB MAC and colleagues developed a letter Better data for country-level TB resource allocation are urgently required available here. The Supplementary data used and a checklist developed for this letter is available below.
