Outpatient thyroid surgery: should patients be discharged on the day of their procedures?
Bibliographic record
Abstract
BACKGROUND: Outpatient surgery benefits patients and surgeons alike, as it is convenient, safe and cost-effective. We sought to assess the safety and feasibility of outpatient thyroid surgery (OTS) at an ambulatory site affiliated with a teaching hospital. METHODS: We performed a retrospective chart review of patients who underwent hemithyroidectomy, subtotal thyroidectomy, total thyroidectomy or completion thyroidectomy between 2002 and 2004 at the Riverside campus of The Ottawa Hospital. We analyzed patient outcomes based on hospital admission and readmission rates as well as complication rates. RESULTS: Two hundred and thirty-two patients met our inclusion criteria. Most patients were women (84%) with a mean age of 47 years. Of these patients, 43 had total thyroidectomies, 75 had subtotal thyroidectomies, 42 had left hemithyroidectomies, 57 had right hemithyroidectomies and 18 had completion thyroidectomies; 26% of these procedures were performed to treat cancer. Other pathologies included multinodular goitre (37%), adenoma (21%), nodular hyperplasia (12%) and Hashimoto thyroiditis (4%). The mean duration of surgery was 87 (range 50-150) minutes. No patients died or underwent reoperation. Complications included hypocalcaemia in 6 patients, hematoma in 1 patient, vocal cord injury in 1 patient and wound infection in 2 patients. All patients but 1 were discharged within 10 hours of surgery; the hospital admission rate was 0.4%. Four patients were readmitted within 1 week of surgery (2 for hypocalcemia, 1 for wound infection and 1 for pain control). CONCLUSION: Outpatient thyroid surgery is safe and is associated with a low complication rate.

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.
