Eliciting an insightful history of present illness JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 647 OP 651 VO 164 IS 5 A1 Redelmeier, Donald A.

YR 2001 UL http://www.cmaj.ca/content/164/5/647.abstract AB THIS ARTICLE PRESENTS THE RESULTS OF A REVIEW of studies of psychology that describe how ordinary human reasoning may lead patients to provide an unreliable history of present illness. Patients make errors because of mistakes in comprehension, recall, evaluation and expression. Comprehension of a question changes depending on ambiguities in the language used and conversational norms. Recall fails through the forgetting of relevant information and through automatic shortcuts to memory. Evaluation can be mistaken because of shifting social comparisons and faulty personal beliefs. Expression is influenced by moods and ignoble failures. We suggest that an awareness of how people report current symptoms and events is an important clinical skill that can be enhanced by knowledge of selected studies in psychology. These insights might help clinicians avoid mistakes when eliciting a patient's history of present illness.
