Nine people accounted for nearly 2,700 of the emergency room visits in Central Texas during the past six years at a cost of $3 million to taxpayers and others, according to a report. The patients went to emergency rooms 2,678 times between 2003 and 2008, said the report from the nonprofit Integrated Care Collaboration, a group of hospitals and other healthcare providers that treat low-income and uninsured patients in Central Texas.
