報告摘要:
The Cancer Centers designated by the National Cancer Institute (NCI) form the “backbone” of the cancer care system in the United States. Awarded via a grant using a peer-review process, a NCI-designated Center (NCI center) receives substantial financial support from NCI grants and is re-evaluated every 3 to 5 years. This talk evaluates geographic and racial disparities in spatial accessibility to the NCI centers and examines various planning scenarios to minimize the inequalities in accessibility. Two scenario of optimization are considered in this research for the objective of minimizing inequality of spatial accessibility. One is to adjust the capacities of NCI centers, and the other is to designate new centers from the existing academic medical centers (AMCs). Both scenarios are assessed in addressing geographic and racial disparities explicitly. Quadratic programming and integer programming are used to solve different optimization problems. Results from the study may inform the public policy decision making process in planning of the NCI centers towards equal accessibility.
