Objective
This study evaluates how well RBfracture™ version 1.8 detects fractures in pediatric patients in a real-life clinical setting. It specifically assesses RBfracture’s standalone performance — both overall and on medicolegal-relevant fractures — and its impact on the diagnostic accuracy of less-experienced emergency physicians.
Key findings
- RBfracture demonstrated a sensitivity of 92%, specificity of 83%, and accuracy of 87%
- RBfracture demonstrated a sensitivity of 100% for proximal tibia fractures
- Residents using RBfracture improved their sensitivity from 84% to 87%, specificity from 91% to 92%, and diagnostic accuracy from 88% to 90%
- The performance of RBfracture in children <5 years old was not significantly lower than >5 years
- Concerning medicolegal relevant fractures, RBfracture performed best on proximal tibia fractures (100% sensitivity) and medial ankle fractures (96% sensitivity)
- Use of RBfracture resulted in a decrease of missed fractures of 22%
