The Shortage of Trauma Surgeons in the US.

BACKGROUND

As the United States (US) population increases, the demand for more trauma surgeons (TSs) will increase. There are no recent studies comparing the TS density temporally and geographically. We aim to evaluate the density and distribution of TSs by state and region and its impact on trauma patient mortality.

METHODS

A retrospective cohort analysis of the American Medical Association Physician Masterfile (PM), 2016 US Census Bureau, and Centers for Disease Control and Prevention (CDC's) Web-based Injury Statistics Query and Reporting System (WISQARS) to determine TS density. TS density was calculated by dividing the number of TSs per 1 000 000 population at the state level, and divided by 500 admissions at the regional level. Trauma-related mortality by state was obtained through the CDC's WISQARS database, which allowed us to estimate trauma mortality per 100 000 population.

RESULTS

From 2007 to 2014, the net increase of TS was 3160 but only a net increase of 124 TSs from 2014 to 2020. Overall, the US has 12.58 TSs/1 000 000 population. TS density plateaued from 2014 to 2020. 33% of states have a TS density of 6-10/1 000 000 population, 43% have a density of 10-15, 12% have 15-20, and 12% have a density >20. The Northeast has the highest density of TSs per region (2.95/500 admissions), while the Midwest had the lowest (1.93/500 admissions).

CONCLUSION

The density of TSs in the US varies geographically, has plateaued nationally, and has implications on trauma patient mortality. Future studies should further investigate causes of the TS shortage and implement institutional and educational interventions to properly distribute TSs across the US and reduce geographic disparities.
