Abstract

Background and need for innovation: Coaching has many benefits in medical education, but large-scale implementation is constrained by faculty bandwidth, scheduling, cost, and power differentials. Artificial intelligence (AI), specifically large language models (LLMs), offers potential solutions to augment coaching, but limitations remain and refining performance is necessary to create valuable coaching conversations.

Steps taken for development and implementation of innovation: The authors created Coaching with AI-Reinforced Education (CAR-E), an AI coaching agent built using an LLM. Using layered architecture, CAR-E couples real-time speech input and output, retrieval-augmented generation (RAG) for evidence-based coaching, and dual memory system (short-term context and long-term history) to sustain longitudinal dialogue. An iterative design refined CAR-E with users who voluntarily engaged in coaching conversations and provided feedback. Transcripts and user feedback were analyzed to improve CAR-E.

Evaluation of innovation: During the pilot, 37 medical trainees and faculty engaged in coaching conversations. Transcripts showed diverse topics discussed and many strengths and opportunities for improvement. Users reported that CAR-E facilitated self-reflection, clarified goals, and broke complex problems into actionable steps. They also noted formulaic questioning that felt repetitive, superficial attempts to display empathy and difficulty moving conversations forward. Many users were frustrated by CAR-E's strict adherence to coaching competencies, which prevented it from giving advice or suggestions.

Critical reflection on your process: Unlike generic LLMs that default to broad, solution-oriented dialogue, CAR-E was designed for coaching in medical education. Its design incorporates evidence-based knowledge retrieval with curated coaching resources, structured memory to support longitudinal conversation, institutional oversight, and speech integration. These features exemplify responsible AI use in medical education. Despite this architecture, many improvements are planned to create reflective, growth-oriented conversations that augment coaching in medical education.

Building CAR-E:一种用于指导对话的新型人工智能代理。
背景和创新需求:指导在医学教育中有很多好处,但大规模实施受到教师带宽、日程安排、成本和权力差异的限制。人工智能(AI),特别是大型语言模型(llm),为增强教练提供了潜在的解决方案,但局限性仍然存在,改进性能对于创造有价值的教练对话是必要的。为开发和实施创新所采取的步骤:作者创建了AI强化教育辅导(CAR-E),这是一个使用法学硕士构建的AI辅导代理。CAR-E使用分层架构,将实时语音输入和输出、基于证据的检索增强生成(RAG)和双记忆系统(短期上下文和长期历史)结合在一起,以维持纵向对话。迭代设计改进了CAR-E,用户自愿参与指导对话并提供反馈。分析转录本和用户反馈以改善CAR-E。创新评估:在试点期间,37名医学实习生和教师参与了指导对话。成绩单显示了讨论的不同主题以及许多优势和改进的机会。用户报告说,CAR-E促进了自我反思,明确了目标,并将复杂的问题分解为可操作的步骤。他们还注意到,公式化的提问让人觉得是重复的、肤浅的表达同理心的尝试,难以推动对话向前发展。许多用户对CAR-E严格遵守教练能力感到沮丧,这使得它无法提供建议或建议。对学习过程的批判性反思:与一般法学硕士课程默认的广泛的、以解决方案为导向的对话不同,CAR-E是为医学教育中的指导而设计的。它的设计结合了基于证据的知识检索、精心策划的指导资源、支持纵向对话的结构化记忆、机构监督和语音集成。这些特点说明了在医学教育中负责任地使用人工智能。尽管这样的架构,许多改进计划创造反思,成长为导向的对话,以增加医学教育的指导。

期刊介绍: Perspectives on Medical Education mission is support and enrich collaborative scholarship between education researchers and clinical educators, and to advance new knowledge regarding clinical education practices. Official journal of the The Netherlands Association of Medical Education (NVMO). Perspectives on Medical Education is a non-profit Open Access journal with no charges for authors to submit or publish an article, and the full text of all articles is freely available immediately upon publication, thanks to the sponsorship of The Netherlands Association for Medical Education. Perspectives on Medical Education is highly visible thanks to its unrestricted online access policy. Perspectives on Medical Education positions itself at the dynamic intersection of educational research and clinical education. While other journals in the health professional education domain orient predominantly to education researchers or to clinical educators, Perspectives positions itself at the collaborative interface between these perspectives. This unique positioning reflects the journal’s mission to support and enrich collaborative scholarship between education researchers and clinical educators, and to advance new knowledge regarding clinical education practices. Reflecting this mission, the journal both welcomes original research papers arising from scholarly collaborations among clinicians, teachers and researchers and papers providing resources to develop the community’s ability to conduct such collaborative research. The journal’s audience includes researchers and practitioners: researchers who wish to explore challenging questions of health professions education and clinical teachers who wish to both advance their practice and envision for themselves a collaborative role in scholarly educational innovation. This audience of researchers, clinicians and educators is both international and interdisciplinary. The journal has a long history. In 1982, the journal was founded by the Dutch Association for Medical Education, as a Dutch language journal (Netherlands Journal of Medical Education). As a Dutch journal it fuelled educational research and innovation in the Netherlands. It is one of the factors for the Dutch success in medical education. In 2012, it widened its scope, transforming into an international English language journal. The journal swiftly became international in all aspects: the readers, authors, reviewers and editorial board members. The editorial board members represent the different parental disciplines in the field of medical education, e.g. clinicians, social scientists, biomedical scientists, statisticians and linguists. Several of them are leading scholars. Three of the editors are in the top ten of most cited authors in the medical education field. Two editors were awarded the Karolinska Institute Prize for Research. Presently, Erik Driessen leads the journal as Editor in Chief. Perspectives on Medical Education is highly visible thanks to its unrestricted online access policy. It is sponsored by theThe Netherlands Association of Medical Education and offers free manuscript submission.
