This can assist emergency referrers in making a diagnosis when a radiologist's report is unavailable. The aim of this study was to evaluate the accuracy of radiographer PIE in interpreting paediatric trauma radiographs in an Australian emergency department.</p><p><strong>Methods: </strong>A randomised sample of paediatric radiographic examinations (aged 16 years and under) from January 2022 to June 2023 was retrospectively reviewed. The anatomical regions reviewed included the appendicular and axial skeleton, chest and abdomen. The PIE for each examination was compared to the radiologist report to indicate if the radiographer's evaluation was a true negative/positive or false negative/positive value.

Traditional didactic training methods often fail to provide the practical skills needed for effective safety protocol implementation.

Secondary objectives included assessing participant satisfaction, engagement and confidence in applying radiation safety practices.</p><p><strong>Methods: </strong>A 2-year randomised crossover trial was conducted with 39 medical professionals from cardiac catheterization laboratories and orthopaedic theatres. Group A received VR training in Year 1 and didactic training in Year 2, while Group B received the reverse. Radiation exposure was measured using Landauer Vision dosimeters.

Group A, which received VR training in Year 1 followed by didactic training in Year 2, showed significant reductions in radiation exposure during Year 1. Group B, which received didactic training in Year 1 followed by VR training in Year 2, exhibited similar reductions during Year 2.
