OneHealth Tool

“While many costing tools take a narrow disease-specific approach, the OneHealth tool attempts to link strategic objectives and targets of disease control and prevention programmes to the required investments in health systems. The tool provides planners with a single framework for a scenario analysis, costing, health impact analysis, budgeting and financing of strategies for all major diseases and health system components. It is thus primarily intended to inform sector side national strategic health plans and policies.”
World Health Organization, “OneHealth Tool”

The OneHealth tool is a software tool designed to inform costing, budgeting, and integrated national planning and country-level health system analysis in low and middle-income countries. The tool helps national planning teams analysis health system resource needs, cost strategic plans by year and by input, estimate health impact of interventions, and compare estimated costs with available financing. This analysis can be done on a disease-specific basis to evaluate targeted national programs like NCDs and injuries, but is intended to provide an integrated approach to costing analysis across the national health system. 

The development of the OneHealth tool was overseen by the InterAgency Working Group on Costing (IAWG-Costing), comprised of United Nations members from UNFPA, UNICEF, UNDP, UNAIDS, UNWOMEN, WHO, and the World Bank. The software for the tool is developed, updated, and provided free of cost by Avenir Health (formerly the Futures Institute).

The first version of the OneHealth tool was officially released in May 2012 and revisions are continually updated. In 2015, a noncommunicable disease costing and impact module will be available, in addition to models for costing surgical care and human resources for health. 

The AvenirHealth website where the most recently updated version of OneHealth is available for download, also includes detailed instructions on how to use the software. These resources include materials and tutorials on:

  • OneHealth FAQ sheets
  • OneHealth Startup Manual & OneHealth Manual
  • OneHealth Technical Notes & Annexes
  • OneHealth Intervention Input Assumptions Manual
  • Defining the target population PIN and coverage in OneHealth
  • Using OneHealth for program planning

The OneHealth tool is currently available in English, Spanish, French, Portuguese, and Russian. The OneHealth tool is built for Windows, but instructions for Mac users are available.
