Do Outcomes Differ after Rotator Cuff Repair for Patients Receiving Workers' Compensation?
Bibliographic record
Abstract
UNLABELLED: Comparisons of outcomes after rotator cuff repair between Worker's Compensation Board (WCB) recipients and nonrecipients generally do not consider patient, injury, and shoulder characteristics. We compared preoperative differences between WCB recipients and nonrecipients and determined the impact on their 6-month postoperative outcome. We evaluated a prospective cohort of 141 patients with full-thickness rotator cuff tears, 36 of whom (26%) were WCB recipients, preoperatively and 3 and 6 months after rotator cuff repair. Their mean age was 54.0 +/- 10.4 years (standard deviation) and 102 (72%) patients were male. Shoulder range of motion, Western Ontario Rotator Cuff (WORC) index, and American Shoulder and Elbow Surgeons' score were used to evaluate outcomes. We performed regression analyses to control for baseline differences in age, baseline scores, smoking status, symptom duration, injury type, and associated biceps disorder between WCB recipients and nonrecipients. WCB recipients were younger and more likely to smoke, have a traumatic injury, and undergo surgery within 6 months of injury. WCB recipients had lower recovery for all outcomes when these differences were not considered but when differences were accounted for, only 6-month WORC scores were lower in WCB recipients. Clinicians should consider preoperative characteristics before concluding WCB recipients experience less recovery after surgical repair. LEVEL OF EVIDENCE: Level I, prognostic study.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
