The cost of care is going up, and so are concerns about how Arkansans will pay for it all. The latest figures on healthcare coverage don`t calm the fears of those struggling to stay insured. Arkansas is one of the worst in the country when it comes to coverage: 16 percent of adults have no insurance; 22 percent of women are uninsured. Health leaders say the cost of care will only increase, so now is the time to reform the system. They say any solution will have to include both the federal and state government.
