Abstract text (incl. references and figure legends)
Introduction:
Trauma is one of major public health care issue which is costly to society. Differences vary from region to region, but blunt trauma accounts for a large part of the total trauma, and the rates of the falls from heights among the blunt trauma is getting higher. It is serious that falls from heights is often accompanied by severe multiple trauma. Therefore, authors studied the relationship between the height of the fall/other related factors and outcomes including hospital stay/mortality.
Materials and Methods
Retrospective cohort study of the 670 adult falls-from-heights patients visited a regional trauma center for 4 years (from 2014.01.01 to 2017.12.31).
Results
Of total 670 patients, the number of D.O.A patients were 69. The height from falls of the deceased patients was statistically significantly higher than that of the survived patients. (19.4 ± 15.3 m vs. 4.3 ± 4.2, p < 0.001) The AUC of the ROC curve of the height from fall to mortality was 0.879. (Fig.) The sensitivity of 3.75m was 90.7% and 6.5m was 81.4%, respectively. The traumatic brain injury, pelvis fracture, visceral organ injury, age, and the height from fall were statistically significant risk factors in multivariate analysis for mortality (p=<0.001, 0.11, 0,001, 0.004, and 0.03 respectively)
Conclusions
We think the current height for the severe fall injury in CDC field triage for trauma is high and needs to be lower to 3.5 m with about 90% sensitivity for survival.
