Changes in trauma management following the implementation of the whole-body computed tomography: a retrospective multi-centre study based on the trauma registry of the German Trauma Society (TraumaRegister DGU®)

Whole-body computed tomography (WBCT) plays an increasingly important role in the diagnostic assessment of trauma room patients. It is still unclear whether its use has led to changes of trauma room procedures and patient outcomes.
In a retrospective multi-centric study based on the trauma registry of the German Trauma Society (TraumaRegister DGU®), we analysed patients with an ISS ≥ 9 between 2002 and 2013. Two periods of time, i.e. up to 3 years preceding (pre-WBCT) and up to 3 years following the introduction of the WBCT (WBCT-group), were assessed separately for every hospital (TR-DGU Project ID 2014-020).
19,838 patients underwent treatment in 77 hospitals. Of these, 5621 were assigned to the pre-WBCT group and 11,307 to the WBCT group. Basic data did not differ relevantly. The time spent in the trauma room decreased from 77.9 min (pre-WBCT) to 63.3 min (WBCT). Following the introduction of the trauma scan, the number of diagnoses per patient increased from 4.6 to 5.1. The percentage of patients who underwent surgery immediately after the completion of trauma room procedures decreased from 44.5 to 39.1%. There was an increase in mortality from 15.7 to 15.9%.
Routine use of WBCT is not superior to a combination of conventional radiography, ultrasound and focused CT in terms of mortality. The entire process involving the introduction of the trauma scan and the further development of algorithms has caused changes that can be observed in the trauma room setting.
