In the developing world, allocating limited health care resources as effectively and equitably as possible is a top priority.
To address that need, systems engineers at the Georgia Institute of Technology are using computer models to help resource-poor nations improve supply chain decisions related to the distribution of breast milk and non-pharmaceutical interventions for malaria. They are also forecasting what health care services would be available in the event of natural disasters in Caribbean nations.
"We are using mathematical models implemented in user-friendly tools like Microsoft Excel to improve the allocation of limited resources across a network, especially in resource-poor settings," said Julie Swann, an associate professor in the H. Milton Stewart School of Industrial and Systems Engineering at Georgia Tech.
Swann reported on three global health case studies designed to improve the allocation of limited health care resources on Feb. 19, 2012 at the annual meeting of the American Association for the Advancement of Science (AAAS) in Vancouver, Canada.
For the first project, Swann and a group of graduate students created models to strategically determine how a nongovernmental organization (NGO) in South Africa should expand its breast milk donation and distribution network to the whole country. In the network, healthy mothers donate breast milk, which is stored in a local repository, transferred to a milk bank to be processed and then distributed to neonatal units where mothers cannot provide it themselves because of disease status or physical inability.
"We wanted to determine how we could provide breast milk to the most people while also being geographically equitable in terms of access," explained Swann, who holds the Harold R. and Mary Ann Nash chair at Georgia Tech. "We looked at the cost of equity and how that changed the distribution design."
