A year after Gov. Bobby Jindal started turning over the operations of Louisiana's university-run hospital system to outside companies, lawmakers are complaining that they have unanswered questions about the deals. Over the past week, state senators have asked why federal officials haven't signed off on the financing arrangements, what happens if federal approval never comes, and how the state will compensate other hospitals now dealing with a rush of uninsured patients. Jindal chose to impose most of the reduction of federal Medicaid financing on the LSU charity hospital system.
