OBJECTIVE: The objective of this study is to evaluate the role of three-dimensional printing models (3DPMs) in the medical education for undergrade students. METHOD: A comprehensive search was performed across three online databases including Medline, EMBASE, CINAHL, Web of SCI, and Scopus spanning from their inception to October 30, 2024. Studies that satisfied the predefined inclusion criteria were incorporated into the analysis. Data analysis was executed utilizing RevMan 5.4.1. Subgroup analyses were conducted based on various models, and overall effects were estimated using either the fixed effects model or the random effects model. The quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework. RESULTS: A total of 33 studies were included in this study, involving 2716 medical undergraduates. The findings indicate that 3DPMs demonstrated significant advantages over the control group in theory test of the skeletal system with a moderate effect size (N = 646, P < 0.00001, I = 80%, SMD = 0.56, 95% CI 0.20-0.93, Random effect model).Moreover, 3DPMs showed a moderate effect size advantage over the control group in laboratory tests with moderate effect size (N = 299, P < 0.00001, I = 0%, SMD = 0.57, 95% CI 0.34 - 0.80, Fixed effect model). Additionally, 3DP showed advantage over the control group in total tests with small effect size (N = 832, P = 0.20, I = 84%, SMD = 0.26, 95% CI -0.14-0.66, Random effect model). CONCLUSION: 3DPMs serve as a valuable adjunct to traditional teaching methodologies and have the potential to enhance both the theoretical understanding and practical laboratory skills of medical students. Nevertheless, caution must be exercised in interpreting the current findings due to variations in model types, low quality of included studies, and the limited number of studies with small sample sizes.
目的:本研究旨在评估三维打印模型(3DPMs)在本科医学生医学教育中的作用。 方法:对包括Medline、EMBASE、CINAHL、Web of SCI和Scopus在内的三个在线数据库进行全面检索,检索时间跨度从各数据库创建至2024年10月30日。纳入符合预定义纳入标准的研究进行分析。使用RevMan 5.4.1进行数据分析。基于不同模型进行亚组分析,并使用固定效应模型或随机效应模型估计总体效应。使用推荐分级、评估、制定和评价(GRADE)框架评估证据质量。 结果:本研究共纳入33项研究,涉及2716名医学生。研究结果表明,在骨骼系统理论测试中,3DPMs相对于对照组具有显著优势,效应量中等(N = 646,P < 0.00001,I = 80%,SMD = 0.56,95% CI 0.20 - 0.93,随机效应模型)。此外,在实验室测试中,3DPMs相对于对照组显示出中等效应量优势(N = 299,P < 0.00001,I = 0%,SMD = 0.57,95% CI 0.34 - 0.80,固定效应模型)。此外,在总测试中,3D打印相对于对照组具有小效应量优势(N = 832,P = 0.20,I = 84%,SMD = 0.26,95% CI -0.14 - 0.66,随机效应模型)。 结论:3DPMs是传统教学方法的宝贵辅助工具,有潜力提高医学生的理论理解和实践实验室技能。然而,由于模型类型的差异、纳入研究质量较低以及小样本量研究数量有限,在解释当前研究结果时必须谨慎。
