Northwestern Medicine Central DuPage Hospital (CDH) is a 390-bed hospital in Winfield, Illinois, United States, one of twelve hospitals operated by Northwestern Medicine. CDH was the first hospital in DuPage County to perform open heart surgery and the first to perform closed-chest, robot-assisted cardiac bypass surgery in the State of Illinois. , the hospital was ranked 8th on the "Best Hospitals in Illinois" list by U.S. News & World Report, but was not nationally ranked in any specialty. History The Central DuPage Hospital Association was established in 1958 when citizens from Glen Ellyn, Lombard, Wheaton, Warrenville, Winfield and West Chicago banded together to restore a sanitarium located on the hospital's current primary site. After an extensive million-dollar renovation project, Central DuPage Hospital opened on September 16, 1964 with 113 beds and 66 physicians. The hospital saw much change throughout the 1970s, with the opening of a 120-bed pavilion on December 13, 1970, small additions in 1971 and 1972, and a five-story 112-bed patient tower in 1976. The facility and campus continued to expand in the decades that followed, with much of the original structure eventually reused or demolished, culminating in the construction of a new $232 million five-story bed tower with 202 private rooms in 2011. In 2011, Central DuPage Health (the successor parent to the Central DuPage Hospital Association) merged with Delnor Health System, the parent of Delnor Hospital of Geneva, Illinois, to form Cadence Health System. Cadence, in turn, was then acquired by Northwestern Memorial HealthCare, parent of Chicago's Northwestern Memorial Hospital, in 2015.
