To illustrate the stepwise logic the OMNI tool takes from program coverage to health outcome, you will be taken through several impact pathways.

Below (Figure 3) is a comprehensive illustration of key intervention impact pathways integrated within the OMNI Tool. View the two illustrative examples that follow to see the OMNI tool in action.

Figure 3: Example of the interventions and beneficiaries in the OMNI Tool

Anaemia remains a severe public health problem in your program area, where nearly three in five pregnant women suffer from it. IFA supplementation in pregnancy is an evidence-based intervention with traditionally low levels of coverage; evidence has shown that IFA supplementation in pregnancy can reduce the risk of anaemia in pregnancy by 67%. In your program area, the number of pregnant women consuming the recommended 90 or more IFA supplements remains low. The steps of the IFA intervention pathway are illustrated below:

This example considers the burden of anaemia among pregnant women in your program area and follows the impact pathway and efficacy of the intervention captured above. In this scenario, the following information is used:

  • Reach: Your program targets approximately 400K pregnant women
  • Coverage: Your program covered an additional 35% of pregnant women with 90 or more IFA supplements
  • Burden: Approximately 58% of pregnant women suffer from anaemia in your program area and approximately 42% of pregnant women suffer from iron-deficiency anaemia (IDA)

Based on the information provided, The OMNI Tool will estimate the number of cases anaemia averted due to your program.  Should you consider expanding your program to other areas, you could use The OMNI Tool to help identify the greatest opportunity for impact through additional programming investment.

A leading cause of under-five mortality, diarrhoea contributes to nearly 1 in 10 child deaths globally. Critical in the treatment of childhood diarrhoea, zinc when combined with low-osmolarity oral rehydration salts (LO-ORS) has been shown to reduce the duration and severity of childhood diarrhoea in zinc deficient populations, thus contributing to averting child deaths.

The OMNI tool allows you to estimate the program impact in countries based on a few contextual factors:

  • Demographic: population under five, all-cause and diarrhoea-specific mortality (neonatal and under five years)
  • Program monitoring: proportion of additional episodes of diarrhoea treated with zinc and ORS

The steps of the zinc and ORS intervention pathway are illustrated below:

Your organization works at both national and sub-national levels. In the case of this example, programming was carried out in several provinces and therefore required provincial mortality and burden figures. In a stepwise function, the OMNI Tool stratifies burden of diarrhoea among the beneficiary group (e.g. estimate of post-neonatal deaths in the project area and the proportion due to diarrhoea after accounting for deaths in the neonatal period, or first 28 days of life). Next, the intervention effect is applied to the residual pool of cases (based on the number of episodes treated above baseline due to your program’s support). In this example, you assume the following:

  • Reach: Your program targets a specific area of your country with a population of 10M children
  • Coverage: Your program treats an additional 75% of diarrhoea cases
  • Burden: Approximately 41K post-neonatal deaths occur annually, 22% of which are due to diarrhoea (or about 9K)

Through your organization’s targeted programmatic activities in a specific area of your country for the delivery of zinc and ORS in the treatment of diarrhoea, using the OMNI Tool you can estimate child deaths averted. By knowing the health impact of the program, together with the cost of that impact, key stakeholder(s) can leverage this information to further improve and/or expand the program design to maximize impact.
