The CHI St. Alexius Health regional healthcare system was formed in April 2016, when several Catholic Health Initiative healthcare facilities joined together to form the largest healthcare delivery system in central and western North Dakota. The system is comprised of a tertiary hospital in Bismarck, and critical access hospitals (CAHs) in Carrington, Dickinson, Devils Lake, Garrison, Turtle Lake, and Williston and numerous clinics and outpatient services. CHI St. Alexius Health also manages five CAHs in North Dakota which are located in the communities of Ashley, Elgin, Linton, and Wishek, as well as Mobridge Regional Hospital & Clinics in Mobridge, SD.
