Background: The optimal candidates for resuscitative endovascular balloon occlusion of the aorta (REBOA) remain unclear. We hypothesized that patients who experience delays in surgical intervention would benefit from REBOA. Methods: Using the Japan Trauma Databank (2014–2019), patients transferred to the operating room (OR) within 3 h were identified. Patients treated with REBOA were matched with those without REBOA using propensity scores, and further divided based on the transfer time to OR: ≤ 1 h (early), 1–2 h (delayed), and >2 h (significantly-delayed). Survival to discharge was compared. Results: Among 5258 patients, 310 underwent REBOA. In 223 matched pairs, patients treated with REBOA had improved survival (56.5% vs. 31.8%; p < 0.01), although in-hospital mortality was reduced by REBOA only in the delayed and significantly-delayed subgroups (HR = 0.43 [0.28–0.65] and 0.42 [0.25–0.71]). Conclusions: REBOA-treated trauma patients who experience delays in surgical intervention (>1 h) have improved survival.
