Purpose:
To evaluate the effectiveness of management strategies for blunt liver injuries in adult patients.
Materials And Methods:
Patients aged ≥18 years with blunt liver injuries registered via the Trauma Quality Improvement Program (2007-2019) were identified. Management strategies initiated within 24 hours of hospital presentation were classified as nonoperative management (NOM), embolization, surgery, or combination therapy. Patients were stratified by injury grade. Linear models estimated each strategy's effect on hospital length of stay (LOS), intensive care unit (ICU) LOS, ventilator dependence, and mortality.
Results:
Of 78,127 included patients, 88.7%, 8.7%, 1.8%, and 0.8% underwent NOM, surgery, embolization, and combination therapy, respectively. Among patients with low-grade (n = 62,237) and high-grade (n = 15,890) injuries and compared with all other management strategies, NOM was associated with the shortest hospital LOS and ICU LOS. Among patients with low-grade injuries and compared with surgery, embolization was associated with a shorter hospital LOS (9.7 days; P < .001; Cohen d = 0.32) and ICU LOS (5.3 days; P < .001; Cohen d = 0.36). Among patients with high-grade injuries and compared with surgery, embolization was associated with a shorter ICU LOS (6.0 days; P < .01; Cohen d = 0.24). Among patients with low- and high-grade injuries and compared with embolization, surgery was associated with higher odds of mortality (P < .001).
Conclusions:
Among patients presenting with blunt liver injuries and compared with surgery, embolization was associated with a shorter ICU LOS and lower risk of mortality.
