Summary of Sudan's HIV Response: Value for Money in a Low-Level Epidemic

Core Content

This report presents the findings of an allocative efficiency analysis conducted in 2014 for Sudan's HIV response, focusing on how to optimally allocate limited resources to achieve the highest impact in reducing HIV incidence, disability-adjusted life years (DALYs), and long-term costs. The study was commissioned by the Government of Sudan to inform the national HIV strategic plan and a concept note for the Global Fund.

Main Objectives

The analysis aimed to address four key policy questions:

• How to optimally allocate HIV funding to minimize new infections
• How to minimize HIV-related DALYs
• What resource requirements are needed to achieve moderate and ambitious impact and coverage targets
• How to minimize future spending commitments due to new HIV infections

Key Findings

1. Epidemic Overview

• Sudan experiences a low-level concentrated HIV epidemic, with the highest incidence rates among female sex workers (FSW), men who have sex with men (MSM), and clients of sex workers.
• In 2013, Sudan had an estimated 6,376 new HIV infections, with 31% directly linked to sex work.
• General population incidence was less than 0.05%, indicating that the majority of infections occur in key populations.
• FSW and MSM are net transmitters, while general population females are net receivers.

2. Optimal Funding Allocations

• To minimize HIV incidence by 2020, USD 6.4 million in programmatic spending should be reallocated to four high-impact programs:
  • ART: 22% of total HIV funding (up from 12% in 2013)
  • FSW prevention: 15% of total HIV funding (up from 4% in 2013)
  • High-risk men/SW clients prevention: 10% of total HIV funding (up from 4% in 2013)
  • MSM prevention: 6% of total HIV funding (up from 2% in 2013)
• Prevention programs for the general population were not included in the optimal mix.
• PMTCT was not part of the optimal mix at the 2013 funding level due to high costs, but with a reduced unit cost, it becomes a more viable option.

3. Impact on DALYs

• To minimize HIV-related DALYs by 2020, the same reallocations would apply.
• This approach could avert 29,300 additional DALYs (23%) compared to the 2013 non-optimal allocation.
• ART would receive the largest share of funding (25% of total HIV funding or 47% of programmatic spending) due to its effectiveness in reducing AIDS morbidity and mortality.

4. Cost-Effectiveness of Targets

• Achieving a 25% reduction in cumulative HIV incidence and deaths by 2016 requires USD 8.1 million annually.
• For 2020 impact targets, an estimated USD 14 million per year is required (220% of 2013 spending).
• For ambitious 2020 targets, USD 34 million annually is needed (over 5 times 2013 spending).

5. Long-Term Fiscal Commitments

• Allocating resources to key populations and ART scale-up minimizes long-term fiscal costs.
• PMTCT and other prevention programs need to be geographically prioritized and integrated with other public health interventions (e.g., syphilis testing) to improve cost-effectiveness.

6. Sustainability and Efficiency

• The study highlights the importance of targeted prevention and ART scale-up for sustainability and defensibility of HIV investments in a health sector with multiple needs.
• The Optima model used in the analysis is robust and provides a formal method of optimization, estimating intervention impact, cost-effectiveness, and long-term financial consequences.

Methodology

• The Optima model is a mathematical model of HIV transmission and disease progression, using population-based data.
• It provides quantitative and objective allocation of HIV resources across prevention and treatment programs.
• Cost-outcome curves were developed for seven core programs, including ART, PMTCT, and prevention services for key populations.
• The model was calibrated to HIV prevalence and incidence data from Sudan, including data from PMTCT sites and key population surveys.

Key Populations and Programs

• Key populations (KPs) include FSW, their clients, MSM, and other high-risk groups.
• Seven core programs were analyzed:
  • Prevention for FSW
  • Prevention for high-risk men/SW clients
  • Prevention for MSM
  • General population prevention
  • HIV testing and counselling (HTC)
  • ART
  • PMTCT
• The model emphasizes the importance of HTC in identifying cases for ART initiation, especially among KPs.

Funding Trends in Sudan

• Sudan's HIV financing is heavily reliant on external aid, with over two-thirds of funding coming from outside sources.
• In 2013, USD 6.4 million was spent on programmatic HIV interventions, while USD 12.2 million was the total spending.
• Domestic public funding has declined significantly, from USD 6.6 million in 2011 to USD 3.7 million in 2013.
• Public health expenditure was only 2% of GDP in 2012, far below the 15% pledged by the Abuja Declaration.

Conclusion

• The study concludes that targeting prevention and ART to key populations is essential for maximizing impact and minimizing costs.
• The Optima model provides a robust framework for guiding resource allocation across multiple policy objectives.
• The Sudan National AIDS Control Program (SNAP) and other stakeholders contributed significantly to the data and insights used in the analysis.
