Diagnostic Accuracy of Extended Focused Assessment with Sonography for Trauma Performed by Paramedic Students: A Simulation-Based Pilot Study.
Article in Open access emergency medicine : OAEM, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundTraining on how to perform a prehospital extended focused assessment with sonography in trauma (EFAST) has resulted in improved outcomes for trauma patients in several countries. The result of previous studies showed good accuracy despite minimal training. However, data on the diagnostic accuracy among untrained paramedic students and the course length in middle-income countries is scarce. In Thailand, the current paramedic education does not include training on prehospital ultrasounds. In the present study, we aimed to investigate the diagnostic accuracy of EFAST among ultrasound-naïve paramedic students and factors that are associated with successful posttest training.
methodsFinal-year paramedic students attending a 4-year university program were included in this study. A 2-h didactic training session and 1-h hands-on workshop were led by experienced emergency physicians. The diagnostic indices for EFAST interpretation were obtained pretraining and posttraining. The participants' ultrasound image acquisition was also evaluated individually on a mannequin model using a standardized assessment tool.
resultsIn total, 47 paramedic students were voluntarily enrolled and underwent EFAST training. Of these participants, 31 (66%) reported having >1 year of experience in the prehospital field. Four were advanced emergency medical technicians before becoming paramedic students. The sensitivity, specificity, positive predictive value, and negative predictive value after training were 85.7% (95% CI, 81.5-89.3), 81.6% (95% CI, 74.2-87.6), 91.6% (95% CI, 87.9-94.4), and 71% (95% CI, 63.3-77.8), respectively. Previous prehospital experience was not associated with accuracy.
conclusionThis study demonstrated that paramedic students in Thailand were able to achieve a competency comparable with that of other medical professionals in a simulated environment. The total 3 h training course was sufficient for them to acquire EFAST skills.
