Brief Summary

Diagnostic error, Dual process model of reasoning) During the last decade, much emphasis has been placed on system solutions to patient safety problems. However, diagnostic error, despite being responsible for twice as many adverse events as medication error, has received little attention. The rate of diagnostic errors have been estimated to be between 0.6% to 12%.Some estimates are as high as 15%.The rate of negative outcome or adverse effects of diagnostic errors range from 6.9% to 17%. Most authors accept that the dual process model of reasoning explains how clinicians make diagnoses. The purpose of this study is to investigate why diagnostic errors occurred in the emergency departments (EDs).
