Optima | Using Optima
We were fortunate to be able to use this analysis for making the key decision regarding funding distribution between programs targeting the different key affected populations and strengthening the interventions that will be more effective for prevention and control of the HIV epidemic in Georgia. Ketevan Stvilia, HIV program manager – National Center for Disease Control and Public Health, Georgia

Several countries have used Optima analyses to inform their national HIV strategies or to develop concept notes for the Global Fund. Optima is also used in supporting the World Bank with their in-country HIV allocative efficiency analyses.

Optima HIV has been applied in over 40 countries across sub-Saharan Africa, Eastern Europe and Central Asia, Asia and the Pacific, Middle East and North Africa, and Latin America and the Caribbean, with many studies resulting in shifts in policy or programmatic emphases. Below is a sample of case studies from the applications of Optima HIV in Sudan.

Case study: Sudan

In the first half of 2014, the Sudan National AIDS Programme reviewed its National Strategic Programme on HIV and AIDS while at the same time preparing a concept note for submission to the Global Fund for the 2015-17 grant cycle. At this time, the Government of Sudan approached the World Bank with a request to conduct an allocative efficiency analysis to inform the prioritization of the national HIV response and the development of the concept note. These analyses, conducted by the World Bank and using the Optima HIV model, recommended the country increase the focus of its HIV response to antiretroviral therapy (ART) and prevention for key populations including female sex workers (FSW) and men who have sex with men (MSM).

With the same amount of money, this strategic shift in investment was projected to reduce new cumulative infections by 37% by 2020. If more strategic allocations were maintained up to 2030, an estimated additional 49,000 new HIV infections and 14,000 HIV-related deaths could be averted.

When budgets were assigned for 2015-2017, the total amount of funding was less than 2013 levels. However, due to the optimization results, more funding was shifted towards programs targeting key populations, predicted to lead to a reduction of total new infections.
