PICO Question
International Network for Simulation-based Pediatric Innovation, Research and Education
Approach / Design
Two Phases:
1. Radiograph Calibration– Remove educationally poor cases
– Broad sample of expertise
– Use Rasch Modelling to ensure appropriate difficulty
2. Actual Trial– Target Population
