Can Spine Surgery Be Done as an Outpatient Procedure at a University Health Sciences Centre?
Bibliographic record
Abstract
At our centre, discectomies and laminectomies were traditionally done as inpatient surgery. A gradual change in practice was instituted between 2010 and 2014 to try to do these procedures as outpatient surgery. In comparing two 12-month periods, one before implementation and the other after, we found a change in the number of outpatient discectomies from 0 to 47 and laminectomies from 0 to 17. The change was received positively, as evidenced by an increase in total (inpatient and outpatient) discectomies from 54 to 63, laminectomies from 22 to 54 and patients from outside of our LHIN increased from 22 to 28%.(Ontario is divided into 14 regions with healthcare services in each planned, funded, and managed through a Local Health Integration Network.) It was efficacious with no hospital readmissions within 30 days and no change in the rate of patients' self-reported improvement postoperatively. Our findings are consistent with the reports of others that outpatient discectomy is safe and effective with resultant cost savings to the healthcare system. Our early results suggest that some outpatient laminectomies are also possible.

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.
