Are Canadian Outpatient Ambulatory Surgery Centers Safe? An Assessment of 2596 Consecutive Aesthetic Surgery Patients
Bibliographic record
Abstract
Abstract Background Ambulatory surgery centers (ASCs) with same-day discharge criteria are the most common setting for aesthetic surgery in Canada. However, to date, no study has reviewed the safety of outpatient aesthetic surgery performed in the Canadian ASC setting. Objectives The purpose of this study was to evaluate the overall safety profile of aesthetic surgery in ASCs, to determine how often in-hospital resources were utilized following outpatient aesthetic surgery, and to examine how predictor variables impact adverse outcomes in this setting. Methods A retrospective chart review of 2596 consecutive patients who underwent aesthetic surgery over a 40-month period at a single Canadian ASC was performed. Data extracted included demographics, operative details, and postoperative complications. Results A total of 2581 patients met inclusion criteria. The majority of patients were female (91.2%) with a mean age of 37.6 years (range, 18-85 years). Most patients had a BMI in the normal weight range (56.3%), and 70.0% were classified as American Society of Anesthesiologists Class I score. Patients predominantly underwent breast/chest surgery (60.3%) with a procedure duration under 2 h (59.2%). Mean postanesthesia care unit time was 109 min (range, 72-420 min). In total, 10 patients (0.4%) utilized hospital resources in the postoperative period, with 3 (0.1%) direct hospital transfers from the ASC. No patients underwent reoperation in the hospital setting. Overall, 67 (2.4%) patients experienced complications that were managed within the ASC setting. Combined procedures (P = .1367), lipoaspirate volume (P = .53) and procedure duration (P = .92) were not associated with an increased risk of adverse outcomes. Conclusions Aesthetic surgery in the ASC setting is safe, with a low associated complication rate. Utilization of hospital resources in the postoperative period is rare. Level of Evidence: 4 (Risk)

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.
