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 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.
