New research shows that Medicaid recipients have a 13% increased risk for dying while in the hospital than the uninsured. Medicaid patients also have longer, more expensive hospitals stays.

Researchers studied outcomes for nearly 900,000 patients across the United States who underwent one of eight major surgical procedures. They found that patients covered by Medicaid incurred a 97% increased risk for dying while in the hospital, and uninsured patients had a 74% increase in risk compared with privately insured patients.

So why does federal health care law will put 500,000 more North Carolinians on Medicaid?
