Abstract

BACKGROUND Patients who sustain blunt liver trauma and are treated at an American College of Surgeons Committee on Trauma-verified Level I trauma center have an overall lower risk of mortality compared with patients admitted to a level II trauma center. However, elements contributing to these differences are unknown. We hypothesize that practice variation exists between trauma centers in management of blunt liver injury. Our objective is to identify practice variations and their effect on clinical outcomes. METHODS Data from a statewide collaborative quality initiative for trauma were used. The data set contains information from 29 American College of Surgeons Committee on Trauma verified Levels I and II trauma centers from 2011 to 2016. Propensity score matching was used to create cohorts of patients treated at Levels I or II trauma centers. The 1:1 matched cohorts were used to compare in-hospital mortality, management strategy, complications, intensive care unit (ICU) and hospital length of stay, and failure to rescue. RESULTS Four hundred fifty-four patients with grade 3 or higher blunt liver injury were included. Patients treated at level II trauma centers had higher in-hospital mortality than those treated at Level I trauma centers (15.4% vs 8.8%, p = 0.03). Level II trauma centers used angiography less compared with Level I centers (p = 0.007) and admitted significantly fewer patients to the ICU (p = 0.002). The ICU status was associated with reduced mortality (7.2% vs 23.9%, p < 0.001). Despite a lower rate of overall complications, Level II trauma centers were more likely to fail in rescuing their patients (p = 0.045). CONCLUSION Admission with a high-grade liver injury to a Level II trauma center is associated with increased in-hospital mortality. Level II trauma centers were less likely to use angiography or admit high-grade liver injuries to the ICU. This variation in practice may lead to the inability to rescue critically ill patients. Future research should investigate contributors to underutilization of resources for patients with high-grade liver injuries. Level of Evidence Care management, level IV
