Sensitizing medical students to impression formation processes in the patient interview

Area of Science:

• Medical Education
• Cognitive Bias
• Clinical Judgement

Background:

• Patient interviewing skills are crucial for medical students.
• Cognitive biases can influence clinical decision-making.
• Weight bias in healthcare settings is a recognized issue.

Purpose of the Study:

• To investigate how patient weight, presented visually or audibly, affects medical students' judgments.
• To sensitize medical students to potential sources of bias in patient assessment.
• To explore the impact of visual vs. auditory information on bias.

Main Methods:

• Medical students were randomly assigned to four groups.
• Exposure to patient interviews via videotape or audiotape.
• Patient presented as either normal weight or overweight.
• Discriminant analysis of questionnaire responses.

Main Results:

• Students viewing the overweight patient via video showed significantly different impressions and assessments compared to other groups.
• No significant differences in judgment were detected between normal weight and overweight audio versions.
• Visual presentation of patient weight appears to be a key factor in eliciting bias.

Conclusions:

• Visual cues related to patient weight can introduce significant bias in medical students' clinical judgments.
• Medical education should incorporate methods to address and mitigate visual weight bias.
• Sensitization experiments are valuable tools for medical curriculum development.
