The relationship between patient volume and mortality in NSW major trauma service hospitals.

Introduction: Conventional wisdom is that Major Trauma Services (MTS) treating larger volumes of severe trauma patients will have better outcomes than lower volume centres, but recent studies from Europe have questioned this relationship. We aimed to determine if there is a relationship between patient volume and outcome in New South Wales (NSW) MTS hospitals.

Materials And Methods: Retrospective observational study using data from the NSW State Trauma Registry from 2010 to 2019 inclusive.
