    BackgroundWhile transarterial embolization (TAE) is an effective way to control arterial bleeding associated with pelvic fracture, the clinical outcomes according to door-to-embolization (DTE) time are unclear. This study investigated how DTE time affects outcomes in patients with severe pelvic fracture.MethodsUsing a trauma database between November 1, 2015 and December 31, 2019, trauma patients undergoing TAE were retrospectively reviewed. The final study population included 192 patients treated with TAE. The relationships between DTE time and patients' outcomes were evaluated. Multiple binomial logistic regression analyses, multiple linear regression analyses, and Cox hazard proportional regression analyses were performed to estimate the impacts of DTE time on clinical outcomes.ResultsThe median DTE time was 150 min (interquartile range, 121-184). The mortality rates in the first 24 h and overall were 3.7% and 14.6%, respectively. DTE time served as an independent risk factor for mortality in the first 24 h (adjusted odds ratio = 2.00, 95% confidence interval [CI] = 1.20-3.34, p = 0.008). In Cox proportional hazards regression analyses, the adjusted hazard ratio of DTE time for mortality at 28 days was 1.24 (95% CI = 1.04-1.47, p = 0.014). In addition, there was a positive relationship between DTE time and requirement for packed red blood cell transfusion during the initial 24 h and a negative relationship between DTE time and ICU-free days to day 28.ConclusionShorter DTE time was associated with better survival in the first 24 h, as well as other clinical outcomes, in patients with complex pelvic fracture who underwent TAE. Efforts to minimize DTE time are recommended to improve the clinical outcomes in patients with pelvic fracture treated with TAE.© 2021. The Author(s).
