Deaconess was founded in 1892 by a group of Protestant ministers and laymen in a small house on 604 Mary Street, Evansville, Indiana, as a 19-bed hospital. In 1897 the house was moved to the back of the lot. A new building was constructed on the corner and opened in 1899. In October 2022, Deaconess took over four
Southern Illinois facilities and hospitals. The facilities included Heartland Regional Medical Center in
Marion, Illinois, Red Bud Regional Hospital in
Red Bud, Illinois, Crossroads Community Hospital in
Mt. Vernon, Illinois, and Union County Hospital in
Anna, Illinois. In 2023, Deaconess partnered to utilize a Health Catalyst, Inc. enterprise analytics and outcomes which work to improve clinical, operational, and financial domains for the overall health system. In February, Deaconess announced that Memorial Hospital was to be an affiliate of Deaconess. Deaconess started to utilize new artificial intelligence at their command center in August. The system was brought on by Jeff Terry, the CEO for
GE-Healthcare, who created this technology to further healthcare for Deaconess. == Hospitals ==
