Research on the Application of the “Three-Dimensions, Four-Layers, Five-Cycles” Training Model in General Training for Operating Room Nurses

Abstract

This study developed and optimized a novel standardized training system for operating room nurses based on a three-dimensional, four-layer, five-cycle framework, aiming to facilitate standardized and homogeneous nursing talent training in tertiary hospitals. A self-controlled before-and-after design was adopted, with traditional training in 2024 as the control and optimized systematic closed-loop training in 2025 as the experimental intervention. Comprehensive optimizations were made to the training framework, hierarchical content, diversified teaching modes and full-process assessment mechanisms. Relevant training and assessment indicators were compared between the two phases. Results revealed substantial increases in annual training sessions (26.74%), class hours (25.17%) and participations (39.50%). Nurses’ infection control assessment performance, training satisfaction, professional participation and teaching-research achievements were also significantly improved (P＜0.05). This optimized training system effectively expands training coverage, standardizes training procedures, improves nurses’ post competency and promotes continuous nursing quality improvement, which is suitable for wide application in tertiary hospitals.
