The Association of Race, Sex, and Insurance With Transfer From Adult to Pediatric Trauma Centers

Our objective was to investigate whether racial/ethnic-based or payer-based disparities existed in the transfer practices of pediatric trauma patients from adult trauma center (ATC) to pediatric trauma center (PTC) in Pennsylvania.

Data on trauma patients aged 14 years or less initially evaluated at level I and II ATC were obtained from the Pennsylvania Trauma Outcome Study (2008-2012) (n = 3446). Generalized estimating equations regression analyses were used to evaluate predictors of subsequent transfer controlling for confounders and clustering. Recent literature has described racial and socioeconomic disparities in outcomes such as mortality after trauma; it is unknown whether these factors also influence the likelihood of subsequent interfacility transfer between ATC and PTC.

Patients identified as nonwhite comprised 36.1% of the study population. Those without insurance comprised 9.9% of the population. There were 2790 patients (77.4%) who were subsequently transferred. Nonwhite race (odds ratio [OR], 4.3), female sex (OR, 1.3), and lack of insurance (OR, 2.3) were associated with interfacility transfer. Additional factors were identified influencing likelihood of transfer (increased odds: younger age, intubated status, cranial, orthopedic, and solid organ injury; decreased odds: operative intervention at the initial trauma center) (P < 0.05 for all).

Although we assume that a desire for specialized care is the primary reason for transfer of injured children to PTCs, our analysis demonstrates that race, female sex, and lack of insurance are also associated with transfers from ATCs to PTCs for children younger than 15 years in Pennsylvania. Further research is needed to understand the basis of these health care disparities and their impact.
