(Olympia, WA)  --  A bill being heard in a Senate committee would mandate changes at Washington's largest mental hospital.  Senate Bill 6541 would require Western State Hospital to measure progress and goals, with some of the results due by the end of the year.  The hospital is in danger of losing millions of dollars in federal funding by March first if it doesn't make improvements to patient safety, management structure, and basic hygiene.  The bill is being considered by the Senate Reform and Accountability Committee.
