Atlanta-based Grady Memorial Hospital plans to spend $12 million to expand and modernize the emergency room and trauma unit. The majority of the work is aimed at relocating the trauma unit apart from the emergency room. The trauma unit will expand from four to six bays, said Grady spokesman Matt Gove. Emergency crews now rush trauma victims through the emergency room area to reach the trauma unit, which can hamper work for both services. The trauma unit can also become cramped during busy times, Gove told the Atlanta Journal-Constitution.
