Abstract

fetched live from OpenAlex

Background: Trauma educational opportunities for general surgery residents in Canada are uncharacterized. We aimed to characterize these opportunities for and identify factors associated with such opportunities. Methods: We performed a prospective cross-sectional study characterizing trauma educational opportunities within Canadian trauma programs. Data were collected during 1 summer week and 1 winter week. We summarized educational opportunities by trauma site and season and used multivariable modelling to evaluate factors associated with increased likelihood of procedure opportunities. Results: Nine academic trauma centres participated. Most consults (93.9%) and trauma team activations (TTAs) (72.3%) were for blunt injuries, and most presentations were during the summer (67.2% TTAs + consults, 69.3% TTAs). Trauma services cared for a median of 14 (interquartile range [IQR] 10–20) inpatients, 4 (IQR 1–6) patients in the intensive care unit, and 0 (IQR 0–2) patients admitted to another service but subsequently followed by a trauma physician (i.e., consulting patients), which varied across hospitals (p < 0.001). Consult, TTA, nonoperative, and operative procedure volumes varied across sites. The most common operative procedures were laparotomies (36.4%), with 1.33 laparotomies per week per site. For nonlaparotomy operations, the maximum volume was 6 over 2 weeks. More operations occurred during summer (74.2%) than winter. Multivariable modelling determined that penetrating mechanisms (odds ratio [OR] 1.87, 95% confidence interval [CI] 1.11–3.15) and TTAs with a trauma surgeon present (OR 2.37, 95% CI 1.59–3.54) were associated with increased likelihood of procedures. Conclusion: Trauma educational opportunities remain heterogeneous across Canada. Higher volumes of patients with trauma were seen during the summer. Penetrating mechanism and TTAs with a trauma surgeon present appear to increase opportunities to perform procedures. Our results can inform general surgery training programs to optimize resident trauma training in Canada.

Not 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.
