On Sept. 24, 2024, the Mark O. Hatfield Clinical Research Center at the National Institutes of Health (NIH) in Bethesda, Maryland was dedicated. The facility is home to new inpatient units, day hospitals and research labs that connect to the Warren Grant Magnuson Clinical Center, which opened its doors to patients in 1953.

The 870,000 square foot Hatfield center opened to patients in 2005 with 242 inpatient beds and 90 day-hospital stations. Together, the Magnuson and Hatfield centers form the NIH Clinical Center, the world’s largest clinical research complex, serving a dual role: providing humane and healing patient care as well as the environment clinical researchers need to advance clinical science.
