In the last decade, trauma care has become its own speciality. The creation of major trauma centres across the UK highlighted a clear clinical need to advance services for multiple injury patients who are known to have poor prognostic outcome. The story of trauma care development goes back well before the creation of the National Health Service (NHS). Although originally grouped with emergency medicine, the two have developed into their own distinct branches. This paper highlights key milestones and relationships in the development of trauma medicine alongside emergency medicine, from ancient times to present day, as well as the factors that have made them distinct. Reviewing the past can help medicine move forward.
