Researchers developed an optimization model showing that improving roads can expand access to cancer care in Rwanda, published in Health Care Management Science. The model evaluates road and facility investments over five years under limited budgets, oncologist availability and changing weather.
Why it matters
Butaro Cancer Center was the country's only publicly accessible facility offering comprehensive oncology services at the time of the visit, and heavy rains often wash out the roughly 60-mile route from Kigali. Because only 35% of estimated cancer cases are diagnosed and 75% of those are caught at severe stages, travel barriers carry direct consequences for patients.
The model covers roughly 7,500 road segments, 1,066 population centers and 48 potential facility locations, with projected rainy-season travel falling from six hours to three hours in one scenario. Whether these projected gains would hold under actual budget and staffing constraints remains untested.
The players
Georgia Tech
Georgia Institute of Technology is a public research university in Atlanta, Georgia, known for its engineering and computing programs.
Health Care Management Science
Health Care Management Science is a peer-reviewed academic journal publishing operations research and analytics applied to healthcare management.
The details
Abel Sapirstein, a Ph.D. student in Georgia Tech's H. Milton Stewart School of Industrial and Systems Engineering, developed the model with ISyE faculty Lauren Steimle and Mathieu Dahan. The model accounts for limited budgets, the fixed number of available oncologists who must staff each new facility, and changing weather that can make roads impassable.
Timeline
June to September and December to February are Rwanda's dry seasons, when 70% of Rwandans still travel more than two hours for care.
The model evaluates road and cancer facility investments over a five-year period.
The study was published in Health Care Management Science in 2026.
Big Picture
The study applies industrial-systems optimization methods, the kind developed in Georgia Tech's H. Milton Stewart School of Industrial and Systems Engineering, to decide where to place roads and cancer facilities in Rwanda. It shows operations-research tools being used to allocate scarce oncology staff and infrastructure budgets across a national care network.
For patients living far from oncology services, travel time to diagnosis and treatment can determine whether cancer is caught early. Improved roads and facility placement could shorten those trips, though the study does not set a timeline for implementation.
The takeaway
Access to cancer care depends as much on getting to a clinic as on the clinic itself. Investments in roads and facility siting can be evaluated together to reach more patients under fixed budgets.
