When a Memorable Story Becomes a Dangerous Prescription
A real-world example of Confabulation in action
Context
An urban emergency department frequently treats older patients with complex medication lists and intermittent documentation. Busy clinicians juggle handoffs, incomplete charts, and pressured time windows for treatment decisions.
Situation
A senior ER physician evaluated a 72-year-old patient with fever and suspected bacterial pneumonia. During a packed shift, the doctor verbally recalled treating the same patient a month earlier and, believing the patient had tolerated penicillin-class antibiotics then, ordered intravenous ampicillin before checking the allergy list or prior discharge notes.
The bias in action
The physician unknowingly filled gaps in memory with a coherent but false account — that the patient had no penicillin allergy and previously received a similar antibiotic without incident. Because the recalled story fit the clinical pattern and saved time, the physician did not consult the electronic allergy record or ask the patient/family to confirm. The doctor genuinely believed the memory; there was no intent to deceive. This reconstructed memory displaced the actual, conflicting data (a documented penicillin allergy) that resided in the electronic chart.
Outcome
Within minutes of the first dose the patient developed urticaria and respiratory distress consistent with anaphylaxis and required emergent treatment with epinephrine and ICU admission. The error triggered a hospital safety investigation, a formal adverse event report, and a malpractice claim from the patient’s family.
