Only one of the nine companies bidding to purchase Prince George's County's (MD) healthcare system wants to run the entire network, raising the possibility that bidders may partner to develop more comprehensive proposals. Eight bidders are not interested in or not capable of operating the system on their own, according to Donna Wilson, vice chair of a panel created to find a buyer for the system. Under a Maryland law, the Prince George's Hospital Authority may sell the system in pieces but cannot transfer any part of it until all of it is sold.
