MADISON, Wis. -

Wisconsin health officials have issued a report on their investigation of a Dean Health diabetes nurse educator who mistakenly put thousands of patients at risk of blood-borne illnesses.

Dean Health officials announced last August that the diabetes nurse educator might have exposed nearly 2,400 patients to hepatitis C by mistakenly reusing insulin demonstration pens and finger-stick devices.

The Wisconsin Department of Health Services' Division of Public Health said it found no evidence of transmission of HIV, Hepatitis B or Hepatitis C associated with the nurse's misuse of insulin demonstration devices.

The nurse involved, Stacey Anderson, was fired when Dean Health discovered her mistakes last summer.

Dean Health officials said they have since reviewed training.

Anderson was reprimanded by the State Board of Nursing earlier this year.
