As early as March 1, Sacramento county plans to shutter Capital Health Center and Northeast Health Center to trim about $360,000 from its annual budget. The clinics serve a total of about 10,200 visitors a year, said county spokeswoman Laura McCasland. Some said the new closures could portend disaster, forcing sick people to wait longer for appointments at the remaining clinics, to wait in longer lines for care, and to head to emergency rooms if they are unable to get treatment in a reasonable amount of time.
