A data-driven evaluation of a train-the-trainer program for delirium management in ICUs: a mixed-methods study integrating multidimensional outcome metrics and qualitative insights.

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
Background: Delirium remains a prevalent and serious complication in intensive care units (ICUs), yet the translation of evidence-based monitoring and management into routine nursing practice faces persistent implementation gaps. Sustainable and scalable educational strategies are urgently needed to address this challenge. Objectives: This study employed a mixed-methods approach to comprehensively evaluate the impact of a train-the-trainer (TTT) delirium education program using a multidimensional outcome framework. Quantitatively, we assessed changes in ICU nurses' competencies across the learning, behavior, and results levels of the Kirkpatrick model. Qualitatively, we explored the underlying experiential mechanisms and contextual drivers to explain the quantitative outcomes and inform program optimization. Methods: A mixed-methods quasi-experimental study with an embedded qualitative component was conducted in a tertiary ICU in China. Forty-seven nurses participated in the TTT program. Quantitative data acquisition included validated instruments for delirium knowledge assessment, standardized clinical simulation evaluations using the CAM-ICU tool, and the General Self-Efficacy Scale, collected at baseline and three months post-intervention. For qualitative data acquisition, semi-structured interviews were conducted with 12 purposively sampled nurses to explore experiential learning trajectories, behavioral drivers, and implementation barriers. Thematic analysis was guided by Social Cognitive Theory and performed using systematic coding procedures. Results: Quantitative analysis revealed statistically significant improvements across all outcome metrics: delirium knowledge scores ( Conclusion: The TTT program significantly enhanced ICU nurses' delirium care competencies, driven by simulation-based practice, repeated application, and peer teaching. Contextual challenges and the need for standardized video resources inform future implementation and fidelity considerations. This study provides a feasible, scalable framework for evidence-based delirium care.
