89 The Effect of Trauma Center Status and Burn Verification Process on Burn Patient Outcomes

Abstract

Abstract Introduction Burn center verification was implemented to ensure burn patients receive the best quality of care. As part of the of the organized burn care system, trauma centers that do not have a burn center within the hospital should refer burn patients to a designated burn center. However, more than 30% of burn patients are still being taken care of in non-verified burn centers. Our aim was to determine if trauma center status conferred a benefit in outcomes in a national sample of burn patients. Methods This is a retrospective study using State Inpatient Databases of 22 states in 2014. The inclusion criteria were all patients admitted for burn injury (ICD-9 codes 940–949). Hospitals were categorized as ABA verified centers (VBC) and non-verified burn centers (NVBC), as well as trauma centers (TC) and non-trauma centers (NTC) based on verification status at the time of admission. Main Outcomes were in-hospital mortality and length of hospitalization (LOS). Stratifying by burn center verification status, multivariable regression was used to identify the association between trauma center status and the outcomes. Results A total of 15,982 burn patients were identified. The overall in-hospital mortality rate was 2.45%. In our sample, we only had 26 hospitals that were both a TC and VBC (Table 1). The majority of patients (54%) were treated at a NVBC/TC. In unadjusted analysis, amongst verified centers, there was no difference in mortality between TC and NTCs (3.2% vs. 3.0%, p=0.877), but NTCs had longer LOS (14.7 vs. 10 d, p< 0.001). Amongst non-verified centers, TCs had higher mortality when compared with NTCs (2.4% vs. 1.1%, p< 0.001), but TCs had longer LOS (8.3 vs. 7.2 d, p=0.007). After adjusted analysis, within VBC, TC status was associated with shorter LOS (Coef -3.28, 95% CI -5.37 – -1.19, p=0.002), but not associated with mortality (OR 1.21, 95% CI 0.50 – 2.89, p=0.667). After adjusted analysis, within NVBC, TC status was associated with longer LOS (Coef 2.37, 95% CI 1.70 – 3.04, p< 0.001) and with mortality (OR 3.70, 95% CI 2.10 – 6.51). Conclusions Trauma center status does not confer any benefit for burn patient outcomes within the burn care verification system. Despite the regionalization of burn care through the development of verified burn centers, the majority of burn patients are receiving care at trauma centers with a non-verified burn center within the hospital.
