Le Bonheur Children’s Hospital

I am a pediatric surgeon with a clinical and research focus on pediatric trauma. I have been the Trauma Medical Director at Le Bonheur Children’s Hospital for 5 years. Le Bonheur is a ACS-verified level 1 trauma center in an urban community with approximately 2000 trauma admissions each year. My general surgery training occurred also in Memphis where I spent many months training at one of the busiest adult trauma centers in the country, the Elvis Presly Memorial Trauma Center, which treats over 1300 firearm injuries each year. The importance of decreasing firearm injuries was apparent then and was brought to the forefront in 2017 when we saw a spike in firearm injuries in children at my trauma center. A research approach at our institution found a large increase in 2017 in firearm injuries with much worse increase since the COVID 19 pandemic. Since that time, I have worked extensive both in and out of the hospital to support and prevent firearm injuries in children.

In 2019, we conducted a study which reported a two-fold increase in adverse childhood experiences in our trauma clinic. This data lead to funding to bring Mental Health Counselors into the hospital to provide integrated behavorial health to injured children and their families. Through this work, we identified an increase in acute stress scores in children that were victims of gunshot wounds. Concurrently, we received city government funding to start a hospital-based violence intervention program to support victims of violent injuries and prevent further injuries. I have been working extensively in the community to build partnerships to prevent community violence and treat our families after violence has occurred. We have partnerships with the city and county government, the school system, community interrupters and juvenile court. The last partnership has grown with federal funding to extend the wraparound services we provide to victims of violent injuries into juvenile court utilizing a primary prevention model to support children before injury occurs.

This study will assess school enrollment in pediatric trauma patients and compare violent vs non-violent injuries. In taking a public health approach to decreasing firearm injuries, we must identify risk factors for violent injuries (truancy) and build programs to modify those factors.
