(AP) — A battle intensified on Monday between LSU and Tulane University over a new teaching hospital in New Orleans, after the LSU System Board of Supervisors proposed a plan that would boost LSU’s clout on the hospital’s governing board.Tulane officials quickly rejected the LSU board’s version of a preliminary plan that would give LSU five appointees on an 11-member hospital board.Tulane’s Board of Trustees last week approved a plan giving LSU four seats on a 12-member board. LSU board members amended the plan after voicing frustration that LSU would not have significant control over a project in which the school would be responsible for backing $400 million in bond debt for the 424-bed hospital, estimated to cost $1.2 billion.”We’re the ones taking all of the financial risk,” board member Rod West of New Orleans said. “LSU … is the only one on the hook.”LSU’s move essentially sent the plan back to Tulane, though Tulane spokesman Mike Strecker said the board of the private New Orleans university is finished negotiating it. Tulane issued a statement saying the LSU board’s move “indicates that Tulane and LSU have fundamental and philosophical differences with respect to the board composition and the appropriate safeguards and independent oversight of the proposed academic medical center.” “Given the importance of the unresolved issues to the community and the state, Tulane believes the matter should now return to the Legislature and the administration for further action.” John Lombardi, LSU system president, tried to downplay the dispute. He said his board’s action was a positive sign: Only one significant point of disagreement remains, over how to manage the proposed hospital in downtown New Orleans. But given the impasse, it was unclear how the project will proceed. “I have said that in order to have a successful academic medical center, we need the combined support of LSU and Tulane,” said Alan Levine, Gov. Bobby Jindal’s health secretary.
