The integration of basic science mechanistic knowledge (pathophysiology and etiology) with clinical features (signs and symptoms) during learning leads to robust cognitive representations in novices and supports the development of clinical reasoning, including better diagnostic accuracy and later learning of related concepts. However, previous studies have used a limited scope of traditional biomedical sciences, including biochemistry, anatomy, and physiology. The use of extended forms of foundational knowledge, including behavioral and sociological sciences, that have been proposed to support learning and performance in complex health systems remains unexplored.
Thirty-three first-year medical students from the University of Toronto MD Program participated in the study. The effect of integrated extended basic science (EBS) learning was compared with that of clinically focused instruction on an initial assessment of diagnosis using clinical vignettes and a "preparation for future learning" assessment (PFLA) to assess learning of new related content in medical psychiatry (co-occurring physical and mental health conditions).
Both forms of instruction supported the development of diagnostic ability on initial assessment (t[30] = 1.20, P = .24). On the PFLA, integrated instruction of extended forms of basic science led to superior performance on assessing complex patients' health care needs (t[30] = 2.70, P < .05).
Similar to previous studies using integration of biomedical sciences, the integration of EBS can enhance later learning of new related concepts. These results have implications for curriculum design to support development of expert clinical reasoning.
在学习过程中,将基础科学的机制知识(病理生理学和病因学)与临床特征(体征和症状)相结合,可使新手形成强大的认知表现,并支持临床推理的发展,包括提高诊断准确性和后续相关概念的学习。然而,以前的研究仅使用了有限范围的传统生物医学科学,包括生物化学、解剖学和生理学。扩展基础科学形式的应用,包括行为和社会学科学,这些科学被认为可以支持复杂健康系统中的学习和表现,但尚未得到探索。
33 名多伦多大学医学博士课程的一年级医学生参与了这项研究。将整合扩展基础科学(EBS)学习的效果与以临床为重点的教学进行了比较,前者通过临床病例和“为未来学习做准备”评估(PFLA)来评估对医学精神病学(共病的身心健康状况)中新相关内容的学习,后者则通过临床病例评估初始诊断。
两种教学形式都支持初始评估中诊断能力的发展(t[30] = 1.20,P =.24)。在 PFLA 中,扩展基础科学的整合教学在评估复杂患者的医疗保健需求方面表现更好(t[30] = 2.70,P <.05)。
与之前使用生物医学科学整合的研究类似,EBS 的整合可以增强对新相关概念的后续学习。这些结果对支持专家临床推理发展的课程设计具有启示意义。
