Effects of a Computational Fluid Dynamics-Based Mobile Education Program on Syringe-Based Wound Irrigation

The study aimed to develop a computational fluid dynamics-based mobile wound irrigation education program and explore changes in irrigation pressure control, wound irrigation-related knowledge and performance confidence in syringe-based wound irrigation. This study used a single-group pre-post design. A computational fluid dynamics-based mobile wound irrigation program was developed following the Analysis, Design, Development, Implementation, and Evaluation model. The program enabled learners to manipulate irrigation variables and visualize pressure distribution in real time. Thirty-four participants were recruited. Irrigation pressure was measured using a load cell-based device, and knowledge and performance confidence were assessed pre- and post-intervention. Data were analysed using paired t-tests and content analysis. The mean irrigation pressure increased significantly, although the post-intervention mean remained below the recommended pressure range and the proportion of participants achieving the recommended range rose from 0% to 44%. Knowledge and performance confidence also improved significantly. Qualitative findings indicated enhanced understanding of performance standards, improved technical awareness and reduced uncertainty during skill execution. Participation in the computational fluid dynamics-based mobile education program was associated with improvements in irrigation pressure control, related knowledge and performance confidence in syringe-based wound irrigation. These findings should be interpreted as preliminary because of the single-group pre-post design. Numerical visualization and real-time feedback may be useful educational strategies for facilitating the transition from experience-based skill performance to data-driven practice.
