The same goes for the sideline presence of KPC Health, a Santa Ana, Calif., hospital operator that told the court in a filing Thursday that it would like to participate in an alternate sale process for both Hahnemann and St. Christopher’s and wants to reopen Hahnemann. KPC, which already owns seven hospitals in Southern California and has a pending deal to buy four more out of bankruptcy in its home state for $611 million, also said it was ready to provide a loan to Hahnemann’s parent company to extend the sale process.
