To evaluate the current practice regarding the prevalence and sequence of x-ray and CT scan in diagnostic algorithms for multiple injured patients.All primarily treated patients with ISS ≥ 9 were selected from the TraumaRegister DGU® (years 2008-2015; n = 109,257). Four subgroups of diagnostic algorithm were defined: CT only (group C; n = 63,763), CT before x-ray (group CX; n = 3711), x-ray followed by CT (group XC; n = 33,590), and x-ray only (group X, n = 8193). We analysed the type and sequence of diagnostic procedures and their association with hospital mortality and length-of-stay in the emergency room (ER-LOS).Predominant strategies were CT only (58.4%) and x-ray followed by CT (30.7%). Overall mortality was between 10 and 12% in all subgroups involving CT, and 6.6% in the x-ray only group. Expected mortality was within the 95% confidence of observed mortality except for the CX group (observed 10.0%; CIER-LOS is significantly affected by diagnostic pathway. CT scan alone accelerates ER-LOS, which however was not associated with lower mortality rates. Performing completive x-ray examinations after an initial CT scan seems not to deteriorate mortality rates. |
