General anesthesia is an acceptable choice for hip fracture surgery
Bibliographic record
Abstract
The debate over the optimal type of anesthesia for hip fracture surgery continues to rage. While retrospective evidence in elective total joint arthroplasty has suggested a reduction in complications with neuraxial anesthesia, previous retrospective studies in the hip fracture population have been mixed. Recently, two multicenter randomized, controlled trials (REGAIN and RAGA) have been published that examined delirium, ambulation at 60 days, and mortality in patients with hip fractures who were randomized to spinal or general anesthesia. These trials enrolled a combined 2,550 patients and found that spinal anesthesia did not confer a mortality benefit nor a reduction in delirium or greater proportion who could ambulate at 60 days. While these trials were not perfect, they call into question the practice of telling patients that spinal anesthesia is a "safer" choice for their hip fracture surgery. We believe a risk/benefit discussion should take place with each patient and that ultimately the patient should choose his or her anesthesia type after being informed of the state of the evidence. General anesthesia is an acceptable choice for hip fracture surgery.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
