Tufts Medical Center and MetroWest Medical Center announced they will collaborate to provide advanced pediatric care in MetroWest's Framingham (MA) Union Hospital. Doctors from the Floating Hospital for Children in Boston will boost the pediatrics department at Framingham Union Hospital with staff to oversee general care and with specialists for premature babies and children with complex medical needs. The arrangement will allow MetroWest to care for infants and children with more serious conditions, instead of referring them to academic medical centers in Boston.
