Abstract
It is unclear whether current practice reflects current evidence on predictors of clinically important outcomes like mortality and fixation failure. Knowledge of predictors of outcome can and should influence treatment decisions and can subsequently improve outcomes. We hypothesized that there is evidence about the significance of predictors of outcome not being considered in the decision making process in the treatment of hip fractures because many surgeons are unaware of it. We surveyed 298 North American and European orthopedic surgeons to examine their training and experience and their opinion on the relative importance of predictors of outcome of femoral neck fracture treatment. We compared the results with the highest level of therapeutic and prognostic evidence currently available. Surgeons' perceptions about the importance of the quality of fracture reduction, patient comorbidities, degree of fracture displacement, dementia, and prefracture walking ability were justified by the current literature. However, we further identified a number of variables deemed unimportant to surgeons that have evidence to support their use in managing patients with hip fractures, including the type of anesthesia as a modifiable variable. In contrast to surgeons' perceptions, the available evidence suggests regional anesthesia is associated with a lower mortality risk than general anesthesia.

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 it
