Abstract：Objective To evaluate the effectiveness of microsurgical skills training for standardized trainers in plastic surgery us-ing the O-AMAS teaching model.Methods Fifty general standardized trainers specialized in burns and plastic surgery,undergoing training at the Affiliated Hospital of Zunyi Medical University from July 2022 to June 2023,were selected for this study.They were divided into two groups randomly:a study group and a control group,with 25 participants in each.The study group received training in microsurgi-cal skills using a teaching model based on the O-AMAS teaching model,while the control group used the traditional microsurgical training method.After the training,the theoretical knowledge scores,skills assessment scores,questionnaire scores,and interest scores of the two groups of trained surgeons were evaluated through theoretical and practical skills assessments and questionnaire surveys.Results The study group's standardized trainers had a significantly higher theoretical knowledge score(27.20±2.16)compared to the control group(21.92±2.61)(t=7.79,P＜0.0001).Similarly,the study group's standardized trainers had a significantly higher skill assessment score(39.24±3.15)than the control group(33.60±3.29).The study found a statistically significant difference between the two groups(t=6.19,P＜0.0001).The satisfaction scores of the surgeons in the study group(45.72±2.57)were significantly higher than those in the control group(26.36±5.90)(t=15.04,P＜0.0001).The study group of regulated surgeons had interest scores of(4.04±1.17),while the control group had interest scores of(2.44±1.08).The difference between the two groups was statistically significant(t=0.51,P＜0.0001).Conclusion The O-AMAS teaching model demonstrated a high level of effectiveness in training standardized trainers in plastic surgery microsurgical skills.The model significantly improved participants'theoretical knowledge,practical skills,and engagement,leading to better learning outcomes and higher satisfaction.
