Doctors at a community hospital in New York City that is part of a large system of hospitals say they are being squeezed out so the system can sell off property in popular neighborhoods. The doctors contend that the parent company, Continuum Health Partners, has been downsizing the institution where they work, Long Island College Hospital in Brooklyn, and diverting resources to its more prestigious hospitals in Manhattan, primarily Beth Israel Medical Center. The doctors estimate that the system had already sold off $50 million in property belonging to their hospital, and have filed formal complaints with the State Health Department and attorney general's office seeking to terminate membership in the Continuum system.
