Abstract

Background: Racial, ethnic, and socioeconomic disparities have been shown to exist in trauma patients. Management of blunt splenic injuries (BSIs) can include splenectomy, embolization, or nonoperative management. This study assesses the effect of race and insurance status on outcomes in patients after blunt splenic trauma. Methods: The National Trauma Data Bank was used to study patients aged 15-89 y with BSIs from 2013 to 2015. Patients with abbreviated injury scores greater than two in nonabdominal areas, excluding extremities, were eliminated, as were patients with other concomitant abdominal injuries requiring repair. Variables of interest were compared across groups using chi-square tests, and those with significant associations were used in multivariate regression models for each outcome. Results: We analyzed 13,537 BSI patients. Uninsured patients had increased odds of mortality, more splenic operations, and were less likely to have nonoperative management (P < 0.001). Uninsured patients were also twice as likely to be discharged home and three times as likely to leave against medical advice (P < 0.001). African Americans and Hispanics had higher mortality (odds ratio [OR] 2.03, CI 1.34-3.08; OR 1.58, CI 1.03-2.44, respectively). African Americans had more splenic operations (OR 1.33, CI 1.08-1.64) and were 60% less likely to receive angioembolization (CI 0.41-0.84). Hispanics had fewer splenic operations (OR 0.79, CI 0.63-0.98). Conclusions: Noteworthy differences exist in the management of splenic trauma patients based on race/ethnicity and socioeconomic status, despite controlling for demographics and injury characteristics. Insurance status and race likely affect surgical treatment plans and mortality, particularly for uninsured, black, and Hispanic patients, but further research is needed to identify the root cause of these disparities.
