目的：本文描述了一项研究，该研究测量和比较了暴露在中高保真度人类患者模拟人身上的护生的知识获取。背景：在澳大利亚和国际上，模拟学习环境的使用已经升级。模拟需要大量的时间和金钱投入，在经济合理化时期，这种投资必须是合理的。用多项选择题评估知识获取是确定模拟体验有效性的最常用方法。方法：这项研究是在澳大利亚一所护理学校进行的，84名三年级护生参加了研究。本研究采用准实验设计，研究了人体模型保真度水平对知识获取的影响。数据收集在三个时间点：模拟前、即刻和两周后。结果：控制组(中等保真度)和实验组(高保真度)在测试1、2和3中的平均得分差异使用独立的t检验计算，没有统计学意义。使用协方差分析(ANCOVA)来确定知识分数是否随时间发生变化，虽然分数有改善，但没有统计学意义。结论：当与高保真人体模型相关的成本增加可能无法用伴随的学习结果增加来解释时，这项研究的结果提出了关于投资昂贵的模拟模型的价值的问题。这项研究还表明，多项选择题可能不是衡量模拟有效性的最合适的衡量标准。
AIM: This paper describes a study that measured and compared knowledge acquisition in nursing students exposed to medium or high fidelity human patient simulation manikins.BACKGROUND: In Australia and internationally the use of simulated learning environments has escalated. Simulation requires a significant investment of time and money and in a period of economic rationalisation this investment must be justified. Assessment of knowledge acquisition with multiple choice questions is the most common approach used to determine the effectiveness of simulation experiences.METHOD: This study was conducted in an Australian school of nursing; 84 third year nursing students participated. A quasi-experimental design was used to evaluate the effect of the level of manikin fidelity on knowledge acquisition. Data were collected at three points in time: prior to the simulation, immediately following and two weeks later.RESULTS: Differences in mean scores between the control (medium fidelity) and experimental (high fidelity) groups for Tests 1, 2 and 3 were calculated using independent t tests and were not statistically significant. Analysis of covariance (ANCOVA) was conducted to determine whether changes in knowledge scores occurred over time and, while an improvement in scores was observed, it was not statistically significant.CONCLUSION: The results of this study raise questions about the value of investing in expensive simulation modalities when the increased costs associated with high fidelity manikins may not be justified by a concomitant increase learning outcomes. This study also suggests that multiple choice questions may not be the most appropriate measure of simulation effectiveness.
