Linking Investigations in Trauma and Emergency Research Network Task Order 1

Principal Investigator: Bellal Joseph, MD                 

Funding Source: Department of Defense

Start Date: January 2017 – December 2021

Enrolling: collecting data on up to 10,000 patients locally, and 50,000 patients across the country

Increasing evidence suggests that multiple factors may be responsible for regional variation and outcome differences following traumatic injury. Trauma center admission volume, admission volume changes over time, transport mechanism and EMS training, and trauma center verification processes have recently been shown to play a role. The purpose of the Trauma Quality Improvement Program (TQIP), directed by the American College of Surgeons, is to improve the level of trauma care provided to the nation by characterizing regional outcome differences and promoting focus initiatives to reduce such variation, resulting in outcome improvement for all injured patients.

A recent military review of those deaths, which occurred on the battlefield prior to arrival to a medical treatment facility in Iraq and Afghanistan (2001-2010), demonstrated that more than 24% of deaths were potentially survivable with more tahn 67% of potentially survivable deaths due to uncontrolled truncal bleeding. The National Academies of Sciences, Engineering and Medicine recommended an integration of military and civilian trauma care including engagement of prehospital care and emergency medical services to establish a national trauma care system with the aim of achieving zero preventable deaths after injury and further minimizing trauma-related disability ( For 2014, the committee estimated that approximately 20% of annual deaths may have been preventable with optimal trauma care and that the greatest opportunity to reduce mortality may reside in the prehospital setting.

Purpose: The purpose of this research study is to collect data from multiple sources, including the pre-hospital and in-hospital settings, from trauma centers across the country to and to better characterize injury related factors, management practices and trauma system factors resulting in or associated with preventable mortality.
