MADISON - Wisconsin hospitals showed a 30 percent increase in providing health care services to the uninsured between 2006 and 2011, according to a report released by The Wisconsin Hospital Association Information Center.

The report showed that hospitals provided services to more than 1 million uninsured and low income patients in 2011.

During 2011, Wisconsin hospitals saw 15.8 million outpatient visits, which was a 4 percent increase from 2010. That compares with 2.4 million inpatient days in 2011.

“We’ve seen a steady increase in our hospitals’ outpatient visits over the years as technology and medical advances have made procedures and treatments possible that in the past could only be delivered in the inpatient setting,” said Debbie Rickelman, vice president of the Madison-based Wisconsin Hospital Association Information Center.

The WHA report showed Medicare provided the largest percentage of gross patient revenue in 2011 at 41.6 percent followed by commercial insurance at 37.5 percent. Medicaid provided 14 percent.
