Surgery preference of orthopedic surgeons based on X-rays

Methodology: Generalized linear mixed effects models
Client affiliation: UCLA Medical Center, Department of Orthopaedic Surgery

For this project we are working with orthopedic surgeons from UCLA Medical Center who conducted an online survey that 700+ orthopedic surgeons responded to. In this survey the surgeons were asked about their training (3 categories), their practice (academic vs. private) and what percentage of their practice involves treatment of pediatric patients (4 categories). Then they were shown a series of 10 X-ray images and asked whether they would choose to operate on the patient based on the X-ray. Multi-level modeling is used to examine if there are significant differences in rate of surgery preference based on training, practice and percentage of treatment of pediatric patients the surgeon’s practice involves.
