Evaluation of Nurse-Led Sono-Triage in Identifying the Under-Triage Rate Among Yellow-Triage Patients During Mass Casualty Incidents at a Level 1 Trauma Center in India.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTriage is critical during mass casualty incidents (MCIs). Under-triage during MCIs using existing triage tools may lead to errors in making critical treatment decisions. The point-of-care ultrasound has been used during MCIs to diagnose hemoperitoneum, pneumothorax, long bone fractures, cardiac tamponade, and inferior vena cava (IVC), with good sensitivity and specificity.
objectiveWe explored the impact of nurse-led sono-triage in identifying the under-triage rate among yellow triage patients and inter-rater agreement among nurse performers during MCIs.
methodsThis was a retrospective observational study of four MCIs during Holi festivals encountered at the emergency department of a level one trauma centre in India. After undergoing training, 10 nurses performed extended focused assessment by sonography in trauma (E-FAST) of yellow triaged patients. The findings were recorded and analyzed.
resultsSono triage was done in 438 patients. Eight patients were E-FAST positive, and 430 E-FAST negative patients. These eight patients (1.8%) were then triaged as red and categorized as under-triaged. The interrater agreement between the nurse performers and the radiologist was 100%.
conclusionSono-triage was able to estimate the under-triage rate among yellow triage patients during MCIs. The nurses who performed sono-triage had a good inter-rater agreement with the radiologist. Nurses may be utilized as a task-sharing model to do sono-triage during MCIs.
