Multicenter study of US trauma centers examining the effect of the COVID-19 pandemic on injury causes, diagnoses and procedures.

Background: The COVID-19 pandemic resulted in nationwide social distancing and shelter-in-place orders meant to curb transmission of the SARS-CoV-2 virus. The effect of the pandemic on injury patterns has not been well described in the USA. The study objective is to determine the effect of the COVID-19 pandemic on the distribution and determinants of traumatic injuries.

Examining emergency medical services' prehospital transport times for trauma patients during COVID-19.

Introduction: Longer prehospital times were associated with increased odds for survival in trauma patients. The purpose of this study was to determine how the COVID-19 pandemic affected emergency medical services (EMS) prehospital times for trauma patients.

Methods: This retrospective cohort study compared trauma patients transported via EMS to six US level I trauma centers admitted 1/1/19-12/31/19 (2019) and 3/16/20-6/30/20 (COVID-19).
