Davis Medical Center in Elkins, Broaddus Hospital in Philippi and Webster Memorial Hospital in Webster Springs are now part of Charleston, W.Va.-based Vandalia Health, a 12-hospital system.
The two health systems signed a letter of intent in June for Davis Health to join Vandalia.
Vandalia is also the product of a merger between Mon Health System and the Charleston Area Medical Center. It is now the second-largest nongovernment employer in the state.
