the moment patient care was transferred to either the ambulance service or the emergency department.
The data were analyzed using IBM SPSS Statistics for Windows, version 22.0 (IBM Corp., Armonk, NY, USA). Descriptive statistics were used for impacted treatment, incidence of trauma mechanisms and illnesses, and PHUS diagnostic performance. Normally distributed data are reported as mean ± standard deviation (SD), data with a skewed distribution are reported as median with an interquartile range (IQR). The interquartile range (IQR) was cal- culated using Tukey’s hinge technique. Pearson’s chi-squared test was used to test for differ-
ences in trauma mechanisms and illnesses between the Radboudumc and non-Radboudumc
