BackgroundThe spleen is a commonly injured intra-abdominal organ from blunt trauma. In cases of traumatic blunt spleen injury, immediate treatment is often required. This study aimed to investigate the prognostic impact of the establishment of a trauma center on the treatment of patients with blunt trauma injury to the spleen.MethodsWe retrospectively reviewed 235 patients who visited our center from 2012 to 2019 for blunt trauma injury to the spleen. The study period was divided into two groups: January 2012 to September 2015 was the pre-center period (PCP), and September 2015 to December 2019 was the trauma center period (TCP). In each period, there were three treatment groups: Surgical group, embolization group, and conservative treatment group. The primary outcome was mortality, and the secondary outcomes were patient characteristics, such as injury severity score and abbreviated injury scale score, time from admission to intervention (both surgery and angiography embolization), and rate of spleen-preserving surgery.ResultsIn the conservative treatment group, the Hb and hct values were relatively low in the TCP than in the PCP (p=0.007, p=0.008, respectively). The intensive care unit admission rate was relatively high in the TCP (72.9% vs. 90.6%, p=0.031). The ISS was relatively low in the TCP (18 vs. 17, p=0.001). In the surgical group, the time taken to transfer patients to the operating room after admission was greatly reduced in the TCP (151 min vs. 107 min, p=0.028). In the embolization group, the patient's age and SBP were lower in the PCP than in the TCP (p=0.003, p=0.049, respectively); three patients had undergone embolization with CPR in the PCP, and no patient underwent CPR in the TCP. There were three deaths in PCP and none in the TCP (p=0.05).ConclusionThe establishment of a trauma center has led to improvements in the treatment quality and prognosis of patients with blunt trauma injury to the spleen receiving either of the three treatments.
