Distorted learning from unusual medical anecdotes.

Doctors are encouraged to look upon each patient as a learning experience ( Wyngaarden , 1979). Case-oriented learning begins in the clinical years of medical school and continues throughout the professional career of the doctor. Clinical cases, or anecdotes, have the potential of producing accurate, relevant and meaningful learning for the clinician even though they are uncontrolled in a scientific sense. However, unusual or atypical cases can also result in erroneous learning which can negatively affect patient care. The purpose of this article is to identify difficulties in this form of subjective learning which can lead to suboptimal doctor practice patterns. Six actual clinical cases are briefly described to illustrate how inaccurate learning distorted subsequent clinical problem-solving by doctors. Suggestions are then made for ameliorating this difficulty.
