(Indianapolis, Ind.) – One-hundred incidents of medical errors were reported in Indiana last year.

Bedsores and surgeries on the wrong body part topped the annual list in the Medical Errors report released Monday by the Indiana State Department of Health.

The exactly 100 errors in 2011 are down from 2010 when there were 107 medical errors logged. Seventeen incidents of retention of a foreign object following surgery were reported in 2011, down from 33 incidents in 2010. The seventeen incidents were the fewest number of foreign object retentions in the six years of the errors report.

In 2011, 41 incidents of pressure ulcers – commonly known as bed sores – were reported, up from 34 in 2010 and the highest number of incidents in six years. Eighteen surgeries were performed on the wrong body part in 2011.

Three of the errors led to deaths or a serious disability for patients.

“The Medical Errors Report is a helpful tool in increasing patient safety awareness,” said State Health Commissioner Dr. Gregory Larkin. “By learning about the types of incidents that could potentially occur while in the care of a hospital or ambulatory surgery center, patients and their families can gain a better understanding of how to assist in the prevention of medical errors.”

Indiana University Health's three downtown Indianapolis hospitals reported the highest number of mistakes, but those three hospitals also had the most patients out of the state's 291 hospitals.
