What is the risk associated with confirmation bias in clinical judgment?

• A. Improving patient trust
• B. Overshadowing critical contradictory information
• C. Enhancing team communication
• D. Facilitating immediate decision-making

Answer: (B)

Confirmation bias is the tendency to favor information that confirms one’s preexisting beliefs or hypotheses while disregarding or undervaluing contradictory evidence. In the context of clinical judgment, this bias can lead healthcare professionals to focus on data, symptoms, or patient history that aligns with their initial diagnosis or assumptions, thereby overshadowing critical contradictory information.

When a clinician becomes overly confident in their initial assessment, they may miss vital signs or alternative explanations for a patient's condition that could ultimately lead to misdiagnosis or inappropriate treatment. This can compromise patient safety and outcomes, as crucial information needed for a comprehensive understanding of the patient's health may be overlooked. Hence, recognizing and addressing confirmation bias is essential for making well-rounded clinical decisions that are based on a complete view of the evidence.
