Cognitive Errors and Debiasing.

Area of Science:

• Medical Education
• Cognitive Psychology
• Patient Safety

Background:

• Medical errors often stem from cognitive biases, not just lack of knowledge.
• Dual Process Theory explains cognitive errors through System 1 (fast, intuitive) and System 2 (slow, analytical) thinking.
• System 1 thinking, while efficient, is prone to biases, necessitating training in cognitive bias and debiasing strategies.

Purpose of the Study:

• To assess the effectiveness of an interactive lecture on dual process theory, cognitive biases, and debiasing strategies for first-year residents.
• To evaluate resident perceptions of knowledge gain, lecture quality, relevance, and likelihood of practice change.

Main Methods:

• An interactive 30-minute lecture on cognitive bias and debiasing was delivered to 14 first-year residents.
• Pre- and post-lecture Likert scale surveys assessed knowledge of cognitive biases and debiasing strategies.
• Post-lecture surveys evaluated lecture quality, relevance, and intended practice changes.

Main Results:

• Post-lecture, 85.7% of residents reported good/extensive knowledge of cognitive biases (vs. 35.7% pre-lecture).
• Post-lecture, 78.6% reported good/extensive knowledge of debiasing strategies (vs. 7.1% pre-lecture).
• All participants rated the lecture highly, found it relevant, and intended to change their practice.

Conclusions:

• An interactive lecture format effectively increased residents' perceived knowledge of cognitive biases and debiasing strategies.
• The positive reception and high likelihood of practice change suggest this educational intervention is valuable for reducing medical errors.
• Interactive lectures can play a key role in introducing essential concepts of cognitive error and debiasing to medical trainees.
