Outcomes of a quasiexperimental study of a hands-on POCUS curriculum in undergraduate medical education.
Article 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
backgroundPoint-of-care ultrasonography (POCUS) education is increasingly provided in medical schools. However, there is a lack of understanding regarding how to teach POCUS to undergraduate students. The aim of this study was to implement and evaluate a teaching strategy within the Internal Medicine clerkship. The Kirkpatrick framework is used to evaluate an educational program on four levels (reaction, learning, behavior, and results). We evaluated our program on the first three levels.
methodsWe enrolled 159 medical students in a single-center, prospective, quasiexperimental study between 2023 and 2024. The intervention comprised a 2-h hands-on session. The participants completed three time-point assessments to test their image interpretation skills (precourse, postcourse, and a 6-month follow-up). Friedman and Dunn's tests were used to compare results. Twenty-six participants were assessed on their ability to acquire images from patients. Satisfaction and behaviors were surveyed. A linear mixed model was applied to identify variables that influence improvements in image interpretation.
resultsAmong the 140 respondents at the end of the clerkship, 136 (97%) were satisfied with the intervention. Among the 78 respondents who completed the follow-up survey at 6 months, 73 (93%) reported that the intervention contributed to their ability to perform POCUS again. There was a significant increase in the interpretation of images assessed at the three time points (9/20 vs. 14.5/20 vs. 14/20, chi-squared = 76.6, p < 0.001), and no significant decline was observed at 6 months (Z = -0.1, p > 0.99). Image acquisition skills (N = 26) suggested high proficiency for non-cardiac views, but substantial challenges in cardiac windows. POCUS application in real patients was reported by 110/140 participants (78.6%) and 42/78 participants (53.9%) during the clerkship and at the 6-month follow-up, respectively.
conclusionsThis teaching strategy was associated with high student satisfaction and significant learning and retention of interpretation skills. Given the non-controlled design and reliance on self-reported behavioral data, these findings suggest a positive impact on undergraduate education rather than establishing definitive effectiveness.
