St. Charles Parish Hospital officials improperly spent almost $6 million in bond money last year for purposes not approved by voters, according to a recent state auditor's report. The public hospital, located in Luling, has been ordered to repay that money to its restricted fund account. The audit, which covers the fiscal year ending June 30, 2012, also showed the hospital ended the year with a $12 million deficit. Hospitals administrators attributed the shortfall to rising health care costs, lower reimbursements and expansion expenses. About $4.7 million of the deficit was attributed to payment for participation in an employee retirement fund.
