Match each of the following clinical scenarios with the specific cognitive bias that most accurately describes the diagnostic error.
- An urgent care physician diagnoses a patient with a viral upper respiratory infection because they have seen twenty similar cases during their current shift, overlooking the patient's distinct unilateral facial pain and purulent nasal discharge.Availability heuristic
- Upon hearing that a patient's initial triage blood pressure was 210/110 mmHg, a physician attributes the patient's altered mental status solely to hypertensive encephalopathy and maintains this diagnosis despite subsequent normal blood pressures and persistent coma.Anchoring bias
- Suspecting fibromyalgia in a patient with widespread body aches, a physician repeatedly asks leading questions about sleep disturbances while actively ignoring the patient's attempts to describe a focal, severely swollen, and erythematous knee joint.Confirmation bias
- An emergency medicine resident evaluates a patient with severe back pain. Because the nursing handover described the patient pejoratively as a 'frequent flyer seeking narcotics,' the resident minimizes the symptoms and fails to work up a spinal epidural abscess.Framing effect
Cevap
Scenario 1 matches the Availability heuristic. Scenario 2 matches Anchoring bias. Scenario 3 matches Confirmation bias. Scenario 4 matches the Framing effect.
Each clinical scenario clearly demonstrates a distinct cognitive bias. The urgent care physician relying on recent URI cases exhibits the availability heuristic. The physician fixated on the initial blood pressure reading demonstrates anchoring bias. The rheumatologist selectively asking questions to support fibromyalgia while ignoring the swollen knee shows confirmation bias. The resident influenced by the pejorative nursing handover demonstrates the framing effect.

Cognitive biases in medical decision-making are systematic errors in thinking that affect clinical judgment, often leading to diagnostic errors and subsequent patient harm. Recognizing specific bias archetypes is critical for implementing cognitive debiasing strategies.
