Fort Carson’s original hospital was erected in 1942 and was located between what is now Prussman Blvd. and Woodfill Rd. It was made of cinderblock construction and painted buff. The ward buildings were two stories, one ward per floor, with a total of 24 buildings and 48 wards. The buildings were connected with covered cement block corridors. The hospital was designed for a normal bed capacity of 1,726 with an expansion capacity to 2,000 beds.

In July 1942, the hospital was organized as an Army Service Forces Station Hospital with a bed authorization varying from 600-1,200, depending on fluctuations in troop density.  Army Service Forces Unit #5022 operated the hospital; the ASU number was an administrative designation for the unit, but the organization was nearly always referred to as US Army Hospital Camp or Fort Carson.

In September 1944, it was activated as a convalescent hospital. This facility and the station hospital already in existence provided treatment for an average 4,500 patients. In January 1945, it was redesignated as the US Army General Hospital, Camp Carson, and included a convalescent hospital. The patient load gradually diminished and by April 1946, the general hospital and the convalescent hospital were inactivated and the station hospital reestablished with a 400 bed authorization.

In May 1946, the Veterans Administration contracted for 100 of the station hospital’s beds. The need for bed capacity decreased after the cessation of hostilities in World War II, and by July 1947 the requirement for the Veterans Administration contract beds was eliminated; the station hospital was reduced to 100 authorized beds. This level remained in effect from 1948-1949.

The bed capacity of the hospital was increased to 400 because of the Korean conflict in July 1950. In February 1951 it was designated a specialized treatment center for orthopedic, psychiatric and neurological cases; and in early 1952 the additional mission of a specialized treatment center for tuberculosis was added.

A 1951 report mentions the attachment of the 807th Station Hospital (300 Bed, CZ) from the reserves. The 807th was under the operational control of the US Army Hospital and ran a dispensary. Beginning with the 1955 report the 807th is no longer mentioned and the 48th Field Hospital is mentioned as attached, but only for training, not under the operational control of the US Army Hospital.

The need for specialization gradually diminished and only the mission of a Class I station hospital existed by March 1, 1954.

In 1955 when the Army Medical Department was re-designated the Army Medical Service (AMEDS) the Army Service Unit designation went away. For a couple years records continued to mention "SU 5022" but after that just AMEDS Activities, Fort Carson. In 1968 the Army Medical Service was re-designated the Army Medical Department and AMEDS Activities became Medical Department Activities - MEDDACs. After the establishment of the Health Services Command in 1973, the hospital unit was officially re-designated as the US Army Medical Department Activity, Fort Carson, with its Soldiers assigned to a Medical Company. HSC was eventually reorganized to become the US Army Medical Command, and the Western Regional Medical Command, was later established as an intermediary command and control organization between the USAMEDCOM and the USAMEDDAC, Fort Carson.

The USAMEDDAC, Fort Carson’s mission remained the same until April 1968, when the hospital was given the additional responsibility of providing care for Vietnam War returnees. The bed capacity was increased to 340 Oct. 1, 1968.

The post-Vietnam drawdown saw doctor shortages in the active force and fostered the routine use of large numbers of civilian healthcare providers in Army medical treatment facilities.

In 1970, planning began for the new Fort Carson Hospital. It was dedicated June 5, 1986, and occupied in July. Evans Army Community Hospital is named in honor of Spec. Four Donald W. Evans Jr., a member of Company A, 2nd Battalion, 12th Infantry Regiment, 4th Infantry Division. Evans was awarded the Medal of Honor for action at Tri Tam, Republic of Vietnam, where he gave his life while administering medical aid to his fellow Soldiers.

The hospital is basically comprised of two distinct buildings separated by a glass-covered common area or atrium. The five-story tower on the north side of the hospital houses all inpatient units, the operating suite, the labor/delivery suite, nursery, radiology, emergency room and the nutrition care division. The two-story clinic building contains a family medicine clinic and other outpatient clinics. The atrium, which provides the main entries into the hospital, also houses patient services such as an outpatient pharmacy, admissions and dispositions, the hospital treasurer, a gift shop and a chapel. 

Adjacent to the hospital is the Woods Soldier Family Care Center.  This is named for Pvt. 1st Class  Eric P. Woods who served as a Combat Medic with the 3^rd Armored Cavalry Regiment and was killed in action in July 2005 during combat operations in Iraq. The WSFCC houses numerous outpatient medical clinics, outpatient records, physical therapy, a family medicine clinic and a dental clinic.

The USAMEDDAC also operates the Mountain Post Behavioral Health Clinic, Robinson Family Medicine Clinic, five Embedded Behavioral Health Teams/Clinics, the Warrior Recovery Center and the Premier Army Health Clinic located in north-central Colorado Springs.

In 2007 the USAMEDCOM established a Fort Carson Warrior Transition Battalion that comes under the command and control of USAMEDDAC.

The USAMEDDAC currently employs about 2,300 military and civilian staff professionals who serve a population of over 71,000 enrolled TRICARE beneficiaries from all military services, Family members and retirees.

Every day USAMEDDAC supports about 3,500 outpatient visits, 41 inpatients, 6 births, 137 Emergency Room visits, 21 operating room cases, and fills 2,806 prescriptions.

The hospital was first accredited by the Joint Commission on Accreditation of Healthcare Organizations in October 1954. Subsequent surveys have reaffirmed the hospital's full accreditation status.
