Objective: We aimed to identify predictive factors of delayed mobilization in ventilated blunt trauma patients. Methods: We retrospectively reviewed 257 consecutive blunt trauma patients who required mechanical ventilation for at least 24 hours between April 2013 and December 2016. The study outcome was the achievement of an upright sitting position out of bed. First, we performed the cumulative incidence function (CIF) approach and the Gray’s test. Second, the Fine-Gray competing risk regression model was applied to investigate the impact of injury location on mobilization. Results: Male sex (P=0.029), injury severity score (ISS) ≥ 25 (P<0.001) and revised trauma score (RTS) <6 (P<0.001) was significantly associated with delayed mobilization. In the Fine-Gray competing risk regression model, spine injury (adjusted hazard ratio 0.64, 95%CI 0.44-0.94, P=0.022) and pelvis/extremity injury (adjusted hazard ratio 0.71, 95%CI 0.53-0.95, P=0.020) were independent predictive factors of delayed mobilization, even after adjustment for sex, ISS and RTS. Conclusion: Sex, high ISS and low RTS, spine injury, and pelvis/extremity injury independently predicted delayed mobilization in ventilated blunt trauma patients.
