CRYSTAL LAKE – Centegra Health System officials say they no longer will admit most patients at their 108-bed Woodstock hospital in a bid to save money and improve care at hospitals in Huntley and McHenry. With fewer patients and losses that topped $30 million through the first three quarters of its fiscal year, Centegra plans to close its intensive care and medical-surgical operations at the Woodstock facility and move those services – and hospital beds – to McHenry and Huntley. The Woodstock facility's comprehensive emergency department would become a basic emergency department under plans approved by the nonprofit's board.
