A Retrospective Proof-of-Concept Study of the Impact of Point of Care Ultrasound During Short-Term Surgical Missions
Bibliographic record
Abstract
Point of care ultrasound (POCUS)-use during short-term surgical missions (STSMs) to resource-limited settings has not been well studied. We conducted a retrospective analysis of POCUS use during the perioperative course of patients undergoing definitive surgical treatment over the course of two STSMs. A total of 58 perioperative POCUS exams were performed by emergency physicians on our team. Operative findings correlated with POCUS results in 90% of cases that underwent surgery, while surgery was deferred based on POCUS findings in 33% of scans. Our findings suggest that POCUS is a portable, rapid and cost-effective modality that can be used in a focused manner in the perioperative period. Specifically, our inter-disciplinary experience and results demonstrate that POCUS-use has a positive impact on patient safety and quality, and optimizes the use of valuable resources and time.

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.
