Other Resources

We welcome you to explore other helpful resources created by the USAID Global Health Supply Chain Program-Procurement and Supply Management (GHSC-PSM) project, including resources like our software tools, technical toolkits, and guidelines. See related resources below for a full list.

OptiDx Software Tool

OptiDx is a web-based, open-access tool to conduct diagnostic network optimization (DNO) and route optimization analysis, for any disease. It enables countries to design diagnostic networks that align with national health goals and supports efforts towards universal health coverage.

Developed in partnership with FIND and Coupa (formerly Llamasoft), supported by the Bill & Melinda Gates Foundation, and hosted and maintained through support by PEPFAR via GHSC-PSM, the OptiDx tool is for ministries of health, donors, and other key stakeholders who work in national laboratory health program development.

OptiDx Helps Teams

  • Weigh possible strategies and recommend solutions based on local contexts to strengthen diagnostic networks and expand access to testing
  • Compare costs and outputs to shape investments for diagnostics systems strengthening
  • Inform evidence-based strategic national plans and guidelines
  • Evaluate the integration of new tests on existing devices
  • Plan procurement or placement of new devices or the procurement of assays
  • Guide funding requests

About OptiDx

  • A network analytics tool designed for diagnostic networks in low- and middle-income countries
  • User-friendly, requiring minimal prior experience in network optimization
  • Highly visual with many pre-populated graphs and charts that can be generated in a click
  • Enables users to model the impact of simultaneous change in multiple parameters on network design and performance

Data Collection Requirements

For optimal tool performance, users will need to collect the following data for each unique geographic area:

Sites and Facilities Information

  • Facility Characteristics:
    • Geocodes (latitude, longitude) of each location
    • Facility Type (ex: Point of care facility, hub, laboratory)
    • Facility Level (ex: City, District, Province, National)
    • Facility Code
  • Equipment Types and Availability
    • Equipment Name
    • Test Type
    • Daily Max Throughout
  • Human Resources/Staffing Levels by Facility
  • Referral Network
  • Demand for tests
