A Review of Radiology Reports From Hip Surveillance Radiographs for Children With Cerebral Palsy
Bibliographic record
Abstract
BACKGROUND: Measurement of migration percentage (MP) is fundamental to successful hip surveillance for children with cerebral palsy (CP). In British Columbia, Canada, children enrolled in the province's hip surveillance program get radiographs at the province's tertiary care pediatric hospital or their local community hospital. This study aimed to review the radiology reporting of images completed as part of hip surveillance. METHODS: Pelvis radiographs completed between September 2015 and December 2019 of 960 children enrolled in the province's hip surveillance program were included. MP values measured by the program coordinator and corresponding value measured by the facility's radiologist, when present, were retrieved. Agreement in MP between the program coordinator and the radiologist was measured using Bland-Altman plots and intraclass correlation coefficients. Radiology reports for images completed at community facilities that prompted a referral to a pediatric orthopaedic surgeon, when reviewed by the hip surveillance team, were further reviewed for qualitative comments. RESULTS: In total, 1849 radiographs were reviewed with 69.3% (1282) completed at the pediatric hospital and 30.7% (567) at 64 different hospitals or clinics. MP was reported for 20.6% (264/1282) of radiographs completed at the pediatric hospital and 3.0% (17/567) of the radiographs completed at community hospitals. Bland-Altman plot analyses found a MP mean difference of 1.2% (95% confidence interval=0.6%-1.8%) between the program coordinator and all radiologist reports with an intraclass correlation coefficient of 0.88 (95% confidence interval=0.86-0.90). There were 47 radiographs completed at community hospitals that resulted in a referral to a pediatric orthopaedic surgeon after review by the hip surveillance team. Eleven of these reports stated normal or unremarkable findings. CONCLUSIONS: Radiologic reporting of images completed for hip surveillance for children with CP was inadequate to allow for the detection of hip displacement. Reporting of MP was rare, particularly in community hospitals. If radiology reporting will be utilized for hip surveillance in children with CP, education of radiologists is required.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
