Spectrum is a suite of easy to use policy models which provide policymakers with an analytical tool to support the decision making process. Models included in the SPECTRUM system are: DemProj, FamPlan, LiST, AIM, GOALS, Resource Needs Model, RAPID, Safe Motherhood and Allocate
The OneHealth Tool is a model to be used for supporting the costing, budgeting, financing and national strategies development of the health sector in developing countries with a focus on integrated planning and strengthening health systems. This model seeks to leverage the most useful components of the different tools that currently exist and is designed in a modular fashion allowing for program specific costing as well as health system component costing.
PrEP-it PrEP implementation planning, monitoring and evaluation tool (PrEP-it)

The PrEP implementation planning, monitoring and evaluation tool (PrEP-it) is a Microsoft Excel-based tool funded by the US President’s Plan for Emergency AIDS Relief (PEPFAR and developed under three projects: the US Agency for International Development (USAID)’s Optimizing Prevention Technology Introduction on Schedule (OPTIONS) Consortium, the Health Policy Plus (HP+) project and the Efficiency and Accountability Technical Assistance to Partners II (EATAP-II) project,).

The National Optimized Treatment Costing (OTC) tool is a tool designed to calculate total and unit costs of different optimized treatment scenarios for antiretroviral therapy (ART). When national level data are entered, the tool can help policymakers undertaking overall national strategic planning. The primary intent of the OTC tool is to serve as a user-friendly tool where cost data from ongoing studies and/or expenditure data can be used to build, compare and conduct analyses.

  • Where will cost savings occur when treatment scenarios are changed?
  • Which optimized treatment scenario provides the greatest cost savings?
  • What is the total projected cost for different treatment scenarios annually for the next five years, by patient type (with sub-totals for key components)?
  • What is the overall unit cost by patient type for different treatment scenarios?

Syphilis Interventions Towards Elimination (SITE) is a dynamic transmission model to evaluate and project impact and cost of syphilis interventions (screening, treatment and prevention) and national control programs. Outcomes include prevalence of active syphilis, incident cases and infections averted, across 7 lower- and higher-risk groups in a national adult population.

The AIDS Impact Model for Business is a tool that is used by businesses to assess how HIV/AIDS may affect their profitability in the future. AIM-B uses a simple approach to calculate the number of workers who are HIV infected, the number of workers who may become HIV infected in the future and determine how this is projected to affect corporate expenditures (e.g., additional health care costs) and revenues (e.g., worker absenteeism). By obtaining this information, it becomes easier for businesses to understand how best to respond to HIV in order to mitigate this economic impact.
