Richard F. Salluzzo, MD, the new chief executive of Massachusetts-based Cape Cod Healthcare, is already putting his mark on the ailing system. Salluzzo has tapped Michael Lauf, chief operating officer of Bristol Regional Medical Center in Bristol, TN, to become chief operating officer of the Cape system. Lauf was a longtime executive from Salluzzo's former company, Kingsport, TN-based Wellmont Health System. Cape Cod Healthcare doctors and other employees say they anticipate additional top level changes at the system, which includes Cape Cod Hospital in Hyannis and Falmouth Hospital.
