ART Costing Tool Crosswalk: HIV/AIDS Program Sustainability Analysis Tool

HIV/AIDS Program Sustainability Analysis Tool (HAPSAT)

Model Methodology

  • Data are gathered from health ministry offices, health care facilities, donors, implementing organizations, and published reports.
  • Costs of HIV treatment are calculated from the unit costs of components such as supplies, pharmaceuticals, laboratory tests, labor hours, facility operating costs, and management costs. Human resource needs are also estimated for each health worker cadre involved in HIV service delivery.

Questions Answered

Analyzes the sustainability of a country’s comprehensive national portfolio of HIV interventions by looking at financial and human resource requirements for achievement of various HIV policy targets over a five-year time horizon and evaluating the resulting resource gaps.

  • How much does the current HIV program cost?
  • How are resources allocated across an HIV program?
  • What are expected future resource gaps for maintaining current or target volume of services?
  • What are the key bottlenecks and when do they appear over time?
  • What would be the implications of particular donors reducing or increasing their financial commitments?

Program Areas

Treatment, care, prevention, mitigation, ART, VCT, pre-ART monitoring, OI prevention and treatment, home-based care, palliative care, testing and directly observed treatment short–course for TB-HIV coinfection, PMTCT, behavior change prevention/abstinence, be faithful, use condoms, most-at-risk population outreach, youth-friendly services, mass media, OVC, economic and social support programs for PLWH, health systems, and shared costs.

Data Outputs

  • Three scenarios are modeled (maintain, scale-up, universal)
  • Outputs include key program impacts (AIDS death, PMTCT, etc.), financial resources required, human resource gap shortfalls
  • Total cost of HIV treatment services for pre-ART, palliative care, first line treatment, second line treatment, and pediatric ART
  • Total cost of HIV treatment services for a given policy by cost category (including health worker labor, ARV medications and supplies, laboratory tests, and overhead health worker time)


  • The model is not currently available in the public domain.
  • It is difficult to measure how well a program is managed (e.g., generate accurate strategic information routinely, efficient organizational systems).
  • There is limited modeling of infrastructure/investment costs.
  • Unit costs do not change for time or coverage, there is no discounting of future costs, HIV incidence is not affected by modeled interventions (i.e., testing and ART do not impact transmission).
  • There is no discounting of downstream costs and benefits.
  • Not yet publicly available.
