Abstract

OBJECTIVE: To investigate the association of lack of insurance and African American race with the probability of transfer to level I/II trauma centers after evaluation in the emergency department of level III/IV trauma centers for traumatic brain injury (TBI).

BACKGROUND: The influence of nonmedical factors on the disposition of TBI patients initially seen in less specialized institutions is debated.

METHODS: We conducted a retrospective cohort study involving TBI patients who were registered in the National Trauma Data Bank between 2009 and 2011. Regression methods were used to investigate the association of insurance status and race with the disposition of TBI patients evaluated in less specialized trauma centers.

RESULTS: During the study period, there were 26,031 TBI patients who were registered in the National Trauma Data Bank and met inclusion criteria. Of these, 10,572 (35.9%) were transferred to a higher level of care institution. Multivariable logistic regression after coarsened exact matching demonstrated an association of uninsured patients with an increased possibility of transfer (odds ratio [OR] = 1.22; 95% confidence interval [CI], 1.05-1.42). On the contrary, there was no association of African Americans with transfers (OR = 1.27; 95% CI, 0.99-1.62). Those with Glasgow Coma Scale score above 8 (OR = 1.22; 95% CI, 1.08-1.39) or Injury Severity Score below 16 (OR = 1.33; 95% CI, 1.13-1.56) had a higher possibility of transfer.

CONCLUSIONS: In TBI patients, lack of insurance was associated with an increased possibility of transfer to higher level of care institutions after evaluation in a level III or IV trauma center emergency department. Regardless of insurance status, this transfer pattern was also observed for African Americans, but only for those with milder injuries.
