minimal travel model assumes a maximum of one thoracic and one abdominal team per donor, from nearest in-state center

2

donor transport model utilizes a facility in Ann Arbor, MI, with shared duty between UMMC and HFH transplant surgeons for procurements. Percent compliance assumes non-transported donors have procurements as per historical data
