The American College of Surgeons (ACS) published a guidance about how to properly set up a RMOC, a Regional Medical Operations Center. It is a single point of shared situational awareness and information that can implement effective command and control for the medical response to a large-scale mass casualty incident. The RMOC allows coordination across all EMS agencies, hospitals, public health representatives, and emergency management leaderships. Therefore, it allows for a better communication and coordination among and between the public health authority, acute and chronic care health systems and EMS.
