Relating Faults in Diagnostic Reasoning With Diagnostic Errors and Patient Harm [PDF]

Academic Medicine, 2012
The relationship between faults in diagnostic reasoning, diagnostic errors, and patient harm has hardly been studied. This study examined suboptimal cognitive acts (SCAs; i.e., faults in diagnostic reasoning), related them to the occurrence of diagnostic errors and patient harm, and studied the causes.Four expert internists reviewed patient records of ...
