BackgroundIn recent years computed tomography (CT) has become faster and more available in the acute trauma care setting. The aim of the present study was to compare injured patients who underwent immediate total-body CT (TBCT) scanning with patients who underwent the standard radiological work-up with respect to 30-day mortality.MethodsBetween January 2009 and April 2011, 152 consecutive patients underwent immediate TBCT scanning as part of a prospective pilot study. These patients were case-matched by age, gender, and Injury Severity Score (ISS) category with control patients from a historical cohort (July 2006-November 2007) who had undergone X-rays and focused assessment with sonography for trauma, followed by selective CT scanning.ResultsDespite comparable demographics, TBCT patients had a lower median Glasgow Coma Score (GCS) than controls (10 vs. 15; p < 0.001) and on-scene endotracheal intubation was performed more often (33 vs. 19 %; p = 0.004). 30-day mortality was 13 % in the TBCT patient group versus 13 % in the control group (p = 1.000). A generalized linear mixed model analysis showed that a higher in-hospital GCS [odds ratio (OR) 0.8, 95 % confidence interval (CI) 0.745-0.86; p < 0.001] and immediate TBCT scanning (OR 0.46, 95 % CI 0.236-0.895; p = 0.022) were associated with decreased 30-day mortality, while a higher ISS (OR 1.054, 95 % CI 1.028-1.08) p < 0.001) was associated with increased 30-day mortality.ConclusionsTrauma patients who underwent immediate TBCT scanning had similar absolute 30-day mortality rates compared to patients who underwent conventional imaging and selective CT scanning. However, immediate TBCT scanning was associated with a decreased 30-day mortality after correction for the impact of differences in raw ISS and in-hospital GCS.
