Plans to reassess the details of a proposed $1.2 billion, 484-bed teaching hospital in downtown New Orleans are raising some concerns about the future of the facility. Louisiana Health and Hospitals Secretary Alan Levine says he is worried that the hospital's current configuration is too expensive and might not qualify for bond financing. As a result, Leveine wants to hire outside experts to "challenge the assumptions" in a business model that said the new hospital would be financially viable.
