Under a new proposal, Ascension Health would take over the struggling Prince George County (MD) hospital system. The system would be subsidized by $495 million in public money, with $297 million coming from the state and $198 million coming from Prince George County. The transfer would take five years and be overseen by an authority with seven members, five appointed by the county and two by the state. The proposal, however, could run into trouble with state officials because of its cost.
