Johns Hopkins is in discussions to integrate Washington-based Sibley Hospital into its health system, they announced Thursday. Both boards have expressed intent to join and said they expected Sibley to be absorbed in early fall. There will not be any financial exchanges. Sibley will keep its name and leadership and day-to-day operations are not expected to change, but Sibley will operate under Hopkins' governance structure and gain access to its clinical medicine and professionals. Hopkins would add patients. Other affiliates in the system are Johns Hopkins Hospital, Johns Hopkins Bayview Medical Center, Howard County General Hospital, Suburban Hospital and Johns Hopkins University School of Medicine.
