IOWA CITY — A former acting director of University of Iowa Health Care’s Central Sterilizing Services is suing UIHC and the Board of Regents for gender and pay discrimination, asserting she was excluded from meetings and decision making, paid less and fired after reporting concerns about bias and unsafe practices.When Courtney Mace Davis, now of Winfield, was terminated in April 2019, the UIHC Central Sterilizing Services she previously led was transitioning from the main campus in Iowa City to a new 48,000-square-foot facility on the Oakdale campus in Coralville.The operation is responsible for cleaning, inspecting, packaging and sterilizing nearly 10 million medical instruments a year.“Ms.
