I am looking for information regarding encountered issues and a communications overview in mass casualty incidents and disasters responses. This should be addressed by doctors, nurses, paramedics and any other participants. Are there radio communication problems on route and at the scene? If so, what does that encompass and can this be quantified? What about the general overview of the intervention, like amplitude, knowing the incident and route beforehand, patient information transmission to the hospital or on arrival, debriefing.
