Medical decision-making is a cornerstone of clinical care and a key contributor to diagnostic accuracy. Medical decision-making occurs via two primary pathways: System 1, pattern recognition, is fast, intuitive, and heuristically driven and occurs largely unconsciously. System 2, analytic thinking, is slow, deliberate, and under conscious control. Biases are systematic errors that can impact reasoning via either pathway but predominantly affect decisions made by pattern recognition. Debiasing strategies involve the deliberate switching from pattern recognition to analytic thinking triggered by a stimulus. This resource describes a faculty development workshop designed to train emergency medicine educators about common biases and debiasing strategies, to improve teaching of diagnostic reasoning to trainees.
This workshop was implemented at the 2017 Society for Academic Emergency Medicine Annual Meeting. The workshop consisted of a brief didactic, followed by small-group case-based learning. A retrospective survey and qualitative evaluation were administered to attendees.
The participants' self-assessment showed significant improvements ( < .001) in their abilities to recognize how pattern recognition can lead to bias, identify common types of bias in the emergency department, teach trainees about common types of bias, and apply cognitive debiasing strategies to improve diagnostic reasoning. Strengths of the workshop included the interactive case-based format, discussions of bias-mitigation strategies, and take-home resources. Suggestions for improvement included lengthening the discussion time and providing more cases.
Cognitive biases can negatively impact patient care. Faculty development is needed to improve instruction about bias and debiasing strategies for all levels of trainees.
医学决策是临床护理的基石,也是提高诊断准确性的关键因素。医学决策主要通过两条途径进行:系统1,即模式识别,速度快、直观且受启发式驱动,主要在无意识状态下发生。系统2,即分析性思维,速度慢、深思熟虑且受意识控制。偏差是系统性错误,可通过任何一条途径影响推理,但主要影响模式识别做出的决策。去偏差策略包括由刺激引发的从模式识别到分析性思维的刻意转换。本资源介绍了一个教师发展研讨会,旨在培训急诊医学教育工作者了解常见偏差和去偏差策略,以改进对学员的诊断推理教学。
该研讨会于2017年学术急诊医学学会年会上举办。研讨会包括简短的理论讲授,随后是基于小组案例的学习。对参会者进行了回顾性调查和定性评估。
参与者的自我评估显示,他们在识别模式识别如何导致偏差、识别急诊科常见偏差类型、向学员传授常见偏差类型以及应用认知去偏差策略以改善诊断推理等方面的能力有显著提高(<0.001)。研讨会的优点包括基于案例的互动形式、对偏差缓解策略的讨论以及可带回家的资料。改进建议包括延长讨论时间和提供更多案例。
认知偏差会对患者护理产生负面影响。需要开展教师发展培训,以改善针对各级学员的偏差和去偏差策略教学。
