Process-oriented feedback for ultrasound-guided central venous access training: a randomized controlled trial.
Trial report in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundProcess mining is an emerging discipline that allows for the analysis of procedural executions performed in a training context, providing objective information about adherence with a normative procedural model (similarity), the number of repetitions of steps (reworks), and performance metrics, which can be used as objective feedback for trainees to guide learning through a process-oriented feedback approach. The aim of this study was to assess whether interventions based on information derived from process mining analysis improve the attainment of procedural proficiency.
methodsTwenty anaesthesia and emergency medicine residents participated in a training program on ultrasound-guided internal jugular central venous catheter placement that took place in a simulated environment. The participants were randomized into a process-oriented training group (n = 10), which received supplementary interventions during training according to the information obtained with process mining tools, and a control group (n = 10), for whom the simulation-based training program was unchanged. Video recordings of each student were obtained before and after the training. Two blinded observers evaluated each recording using a global rating scale (primary outcome) and checklist. Procedure execution time and process-oriented metrics (rework and similarity) were measured. The pre- and posttraining performance indicators were compared within groups and between groups. The interrater reliability of the global rating scale scores was calculated using the intraclass correlation coefficient. We used the Wilcoxon signed-rank test for intragroup comparisons and the Mann‒Whitney test for intergroup comparisons. Statistical significance was set at P < .05, adjusted for multiple comparisons.
resultsThere were no differences between groups in the pretraining measures. During post training, both groups showed improved performance in ultrasound-guided central venous catheter placement compared with their pretraining performance. The global scale results, checklist results, and execution times were not significantly different between the control and process-oriented groups. However, the process-oriented group showed a significant improvement in similarity to the expected performance and a greater reduction in rework than did the control group.
conclusionThe process-oriented approach, along with the procedural training program, decreases rework and increases adherence to the reference process model of the ultrasound-guided central venous catheter in the execution of the procedure in a simulated environment. Moreover, classic procedural assessment indicators do not capture this effect.
