Nashville General Hospital, the city's financially troubled safety-net hospital, is being audited to see if it has addressed the issues identified in a 2005 audit, officials said. But Mayor Karl Dean's finance chief said Dean's administration had not requested the review of Nashville General Hospital at Meharry by the Office of Internal Audit, which is independent of the mayor's office and Metro Council. Any talk about the hospital's future being on the line is premature, Metro Finance Director Rich Riebeling said.
