Non-Doctors as Trauma Surgeons? A Controlled Study of Trauma Training for Non-Graduate Surgeons in Rural Cambodia
Bibliographic record
Abstract
INTRODUCTION: Due to the accelerating global epidemic of trauma, efficient and sustainable models of trauma care that fit low-resource settings must be developed. In most low-income countries, the burden of surgical trauma is managed by non-doctors at local district hospitals. OBJECTIVE: This study examined whether it is possible to establish primary trauma surgical services of acceptable quality at rural district hospitals by systematically training local, non-graduate, care providers. METHODS: Seven district hospitals in the most landmine-infested provinces of Northwestern Cambodia were selected for the study. The hospitals were referral points in an established prehospital trauma system. During a four-year training period, 21 surgical care providers underwent five courses (150 minutes total) focusing on surgical skills training. In-hospital trauma deaths and post-operative infections were used as quality-of care indicators. Outcome indicators during the training period were compared against pre-intervention data. RESULTS: Both the control and treatment populations had long prehospital transport times (three hours) and were severely injured (median Injury Severity Scale Score = 9). The in-hospital trauma fatality rate was low in both populations and not significantly affected by the intervention. The level of post-operative infections was reduced from 22.0% to 10.3% during the intervention (95% confidence interval for difference 2.8-20.2%). The trainees' self-rating of skills (Visual Analogue Scale) before and after the training indicated a significantly better coping capacity. CONCLUSIONS: Where the rural hospital is an integral part of a prehospital trauma system, systematic training of non-doctors improves the quality of trauma surgery. Initial efforts to improve trauma management in low-income countries should focus on the district hospital.

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.
