Blended e-learning with handheld ultrasound devices improves practical competence in eFAST: a randomised controlled study.
Trial report in BMC medical education, 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
backgroundEmergency ultrasound, particularly extended Focused Assessment with Sonography in Trauma (eFAST), is increasingly recognised as essential in undergraduate medical education. Although blended learning offers flexibility, its effect on practical skills remains uncertain. This randomised controlled trial examined whether supplementing voluntary handheld ultrasound practice with digital self-study improved eFAST performance compared with digital preparation alone.
methodsIn this randomised controlled trial, 173 medical students were allocated to a control group (digital self-study; n = 89) or an intervention group (digital self-study plus voluntary handheld ultrasound practice; n = 84). All the students performed a standardised eFAST on a high-fidelity simulator. A blinded rater assessed performance using a modified Objective Structured Assessment of Ultrasound Skills (OSAUS) score (primary outcome). The secondary outcomes were examination duration, complete eFAST achievement, and student feedback. Regression analyses adjusted for potential confounders.
resultsThe intervention group achieved a significantly higher modified OSAUS score (median 16.0 vs. 13.0, p < 0.001), completed examinations faster (median 247 vs. 370 s, p < 0.001), and more frequently performed a complete eFAST (42.9% vs. 23.6%, OR 2.43, 95% CI 1.26–4.67). Adjusted analyses confirmed these associations (OSAUS + 3.29 points; aOR for complete eFAST 2.52; HR for faster completion 4.26; all p < 0.01). Student acceptance was high; intervention participants reported longer preparation times (2.0 vs 1.0 h, p < 0.001) without additional disadvantages.
conclusionsBlended e-learning with handheld ultrasound devices significantly improved eFAST training outcomes, including higher performance scores, shorter examination times, and more complete scans. These findings support the integration of handheld ultrasound practices into the undergraduate curriculum.
trial registrationNot applicable. This study did not involve a health care intervention on patients but focused on educational training in ultrasound techniques for medical students.
