Delaware County's largest hospital system is running on fumes. A $20 million allotment of funding from the Foundation for Delaware County will keep Crozer Health operational in the immediate future, but what happens beyond the next few weeks is unclear. Just two of Crozer Health's four hospitals — Crozer-Chester Medical Center and Taylor Hospital — remain open. Prospect Medical Holdings, Crozer's for-profit parent company, is still trying to sell the ailing system to new ownership.
