Enhancing medical intern competence in urethral catheterization: Impact of simulation-based training on knowledge, self-efficacy, and clinical outcomes.
Article in PloS one, 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
introductionUrethral catheterization is a common procedure, yet most related complications occur when performed by new medical interns. Studies have shown inadequate training and knowledge among junior doctors. This study evaluated the declarative knowledge of new interns regarding urethral catheterization and assessed the effectiveness of a simulation-based urology session in improving their knowledge, confidence, and perceived self-efficacy.
methodsA one-day urology simulation workshop was conducted for 40 new interns at a university hospital. Participants completed a pre-session online questionnaire assessing demographics, urinary catheterization knowledge, and self-reported confidence and self-efficacy. The workshop included three modules: an interactive presentation, instructional videos, and hands-on simulation on male and female models. Post-session assessments measured changes in knowledge, confidence, and self-efficacy scores using standardized evaluation tools.
resultsForty new medical interns participated. Only 15% felt adequately prepared before training. Knowledge gaps were identified regarding catheter types and sizes (92.5%), optimal patient positioning (62%), proper meatus exposure, and balloon inflation technique (100%). Following the workshop, mean knowledge scores increased from 7.7 ± 1.24 to 12.2 ± 1.11, self-reported confidence from 6.60 ± 1.79 to 8.66 ± 0.94, and perceived self-efficacy from 3.32 ± 0.94 to 4.32 ± 0.62 (all p < 0.001). At six-month follow-up, participants collectively performed 274 urethral catheterizations with a 93% success rate and a low complication rate of 4% (n = 11), reflecting effective transfer of learning from the simulation to clinical practice. DISCUSSION: New medical interns demonstrated insufficient baseline knowledge of urethral catheterization. The structured urology simulation session significantly improved their declarative knowledge, confidence, and perceived self-efficacy, underscoring the value of simulation-based training in early postgraduate medical education.
