The OMNI Tool is designed to help the development community, nutrition and non-nutrition agencies, and donors plan and report impacts of nutrition programming. The tool can guide decision making by on-the-ground program implementers, policy makers, and also provides valuable insights for advocacy efforts.


Nutrition organizations, national governments and donors need the ability to prioritize limited resources to the most cost-effective and high-impact nutrition interventions. It is often difficult for organizations to accurately calculate current or future impact of their nutrition programming, especially with multiple interventions. There is often a gap between program coverage and estimating impacts as a result of programming (Figure 1). Building on 20 years of programming experience, Nutrition International (NI) developed the Outcome Modeling for Nutrition Impact (OMNI) Tool to address these challenges.

The OMNI Tool is a modelling tool that integrates program coverage data from the field and intervention efficacy values to calculate relevant health impacts. The tool combines evidence, program coverage data, and NI’s implementation experience. This powerful tool estimates health and non-health impacts that result from nutrition programming, and can be used to estimate impacts across multiple interventions.

Using actual coverage data (provided by the user), the OMNI Tool allows impact reporting for current activities. The tool also guides future program planning scenarios, estimating potential impact of select nutrition interventions. With the tool, users can experiment with program strategy and design to identify the greatest opportunity to make the biggest impact.

The current version of the OMNI Tool estimates health impacts such as:

  • Child deaths averted
  • Anaemia cases averted (among different beneficiary groups)
  • Low birth weight cases averted
  • Stunting cases averted
  • Neural tube defects (NTDs) averted
  • Mental impairments averted

NI has invested in expanding the OMNI Tool to model non-health impacts, which will be publicly available in late 2018. The updated tool will extend current functionality by translating estimated health impacts to other relevant impact outcomes such as:

  • Economic losses averted
  • IQ points and years of education saved
  • Cost per beneficiary

Non-health impacts have the potential to illuminate new pathways that may link nutrition to other social and economic gains that are not yet fully understood or communicated. Although still under development, the potential to generate an additional body of evidence and rationale for existing and future investments in nutrition is greatly needed.
