Strengthening supply chain and logistics management


PATH applies a systematic architected and rational approach to define country needs for supply chain and logistics information management, identify the most appropriate and effective technology solution to address them, and provide technical support in the development and implementation phase.

  • Cold Chain Equipment Manager: Recognizing the urgent need for countries to better plan and manage cold chain equipment such as refrigerators, cold rooms, and cold boxes, PATH developed a software tool called Cold Chain Equipment Manager (CCEM). CCEM can help vaccination programs plan and manage the equipment needed on a facility-by-facility basis, matching equipment specifications with a facility’s energy availability and capacity needs. With support from the US Agency for International Development (USAID), the World Health Organization (WHO), UNICEF, and the Clinton Health Access Initiative (CHAI), CCEM has been implemented into national immunization programs in four countries, including India and Benin.
  • Common Requirements for Logistics Systems: With funding from the Rockefeller Foundation, PATH applied the collaborative requirements development methodology (CRDM) approach with health care workers from Kenya, Rwanda, Senegal, and Vietnam. Through this process, they identified a set of 12 business processes and 208 user requirements common to national supply chain systems. Albania, Rwanda, and Zambia have successfully used these global requirements to develop country-specific plans for new supply chain management systems.
  • Logistics Management Information System (openLMIS): PATH used CRDM to work with Ethiopia, Tanzania, and Zambia to define the requirements for an information system to track logistics. With the requirements in hand, we work with our partners in a systematic and rational approach to design and develop an open-source logistics management information system (openLMIS) that meets the requirements of low-income countries. We provide technical support to the project management team in developing a product vision and roadmap, and during the development and implementation phases of openLMIS. Our partners include Columbia UniversityJohn Snow Inc. (JSI), and VillageReach. This work is funded by the US Agency for International Development and the Bill & Melinda Gates Foundation.
  • VaxTrac Stock Management System in Vietnam: As part of Project Optimize, PATH began working with Vietnam’s National Institute of Hygiene and Epidemiology (NEPI) in 2011 to create a software program that allows users at various levels of the health system to track vaccine stock and report monthly immunization activity. The team piloted VaxTrac in three provinces: Phu Tho, Quang Tri, and Ben Tre as well as at regional and national levels. After the first three months of implementation, NEPI extended the pilot to all districts of one project province and expanded the number of participating provinces to 13. Now that Optimize work has ended in Vietnam, NEPI is looking for funding to scale up the software nationwide.
  • Logistimo Stock Management System in South Sudan: As part of Project Optimize and in partnership with the Government of the Republic of South Sudan and the United Nations Children’s Fund, PATH is testing a cloud-based logistics management information system (LMIS) that uses mobile phones to manage vaccine stock. The new system, named Logistimo, was deployed in May 2012 and is now being used in the central store, the ten state stores, and all six counties of Central Equatoria State. The Logistimo demonstration project in South Sudan aims to evaluate the benefits to immunization programs of more reliable and up-to-date information on stock levels and consumption rates, as well as the feasibility of implementing a mobile phone-based LMIS in remote locations. As part of the demonstration, county stock managers have been provided with mobile phones they can use to register stock transactions and submit orders for additional stock. National or state managers can then use this information to track stock and demand in real time and analyze consumption patterns.
