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
