Objective To evaluate the effectiveness of the GROW coaching model in the standardized training of newly graduated nurses in surgical care. Methods Sixty new nurses recruited in 2021 (control group) and sixty recruited in 2022 (observation group) received traditional training or GROW model-guided training, respectively. Comprehensive assessment score and job competency were compared between the two groups after the 2-year standardized training. Results The observation group demonstrated significantly higher scores than the control group in both the comprehensive assessment and job competency (both P<0.05).Conclusion Implementing the GROW coaching model in the standardized training of newly graduated surgical nurses effectively enhances their comprehensive quality and job competency, thereby contributing to improved patient care quality.
