BACKGROUND: Renal trauma may be managed differently in tiered trauma systems and among those who requireinterfaculty transfer.
OBJECTIVE: To evaluate the initial management of renal trauma, assess patterns of management based on hospital trauma level designation and interfacility transfer status, and analyze management trends over time.
DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of renal trauma from the National Trauma Data Bank 2010-2015. INTERVENTION: Nephrectomy, angioembolization, or nonoperative management. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS: We used generalized estimating equations to compare odds of each management outcome in patients transferred and directly admitted to a level I center, versus those directly admitted to a non-level I center, adjusting for vital signs, injury, demographic, and facility characteristics. We also used generalized estimating equations to examine linear time trends in management outcome, adjusting for injury characteristics.
RESULTS AND LIMITATIONS: A total of 51798 renal trauma records were included: 44 838 low-grade (American Association for the Surgery of Trauma I-III) and 6359 high grade (IV-V) injuries. After adjusting for comorbidities, demographics, and hospital characteristics, odds of nephrectomy, angioembolization, and nonoperative management were similar in patients transferred or directly admitted to a level I center compared with those treated at a non-level I center. Changes in management over time demonstrated a decreased rate of nephrectomy (p=0.007) in high-grade injuries, while the rate of angioembolization remained constant (p=0.33). Study limitations include mortality prior to hospital transfer or arrival, and its retrospective nature.
CONCLUSIONS: In this contemporary trauma analysis, outcomes of both low- and high-grade renal trauma are similar across patients managed in tiered trauma centers and those undergoing transfer, signifying dissemination of collective renal trauma management. The rate of nephrectomy has decreased for high-grade renal injury over our study period, suggesting new adoption of kidney-sparing management. PATIENT SUMMARY: Renal trauma is now managed similarly in tiered trauma centers and in patients requiring interfacility transfer. The rate of nephrectomy for high-grade renal injuries has decreased over time.
