Hahnemann University Hospital‘s owners have filed for chapter 11 bankruptcy, CBS Philly reported. Philadelphia Academic Health System, which also owns Saint Christopher’s Hospital, filed the paperwork shortly after midnight yesterday. Allen Wilen, chief restructuring officer for Philadelphia Academic Health System LLC, says that the move will facilitate a restructuring or sale of St. Christopher’s, allowing it to remain in full operation. The real estate used by the two hospitals wasn’t included in the filing. Last Wednesday, Hahnemann announced it was closing in September because of unsustainable financial losses.
