Medical error poses an important healthcare burden and a challenge for physicians and policy makers worldwide. Diagnostic error accounts for a substantial fraction of all medical mistakes. Most diagnostic errors have been associated with flaws in clinical reasoning. Empirical evidence on the cognitive mechanisms underlying such flaws and effectiveness of strategies to counteract them is scarce....

Diagnostic failure can be due to a variety of psychological errors on the part of the diagnostician. An erroneous diagnosis rendered by previous clinicians can lead a diagnostician to the wrong diagnosis. This report is the case of a patient who misdiagnosed herself and then led an emergency room physician and subsequent treating physicians to the wrong diagnosis. This mechanism of diagnostic e...

An investigation is presented in which a computer simulation model (DIAGNC)SER) is used to develop and test predictions for behavior of subjects in a task of medical diagnosis. The first experiment employed a process-tracing methodolagy in order to compare hypothesis generation and evaluation behavior of DIAGNOSER with individuals at different levels of expertise (students, trainees, experts). ...

Diagnostic errors are a major patient safety concern. Although the majority of diagnostic errors are partially attributable to cognitive mistakes, the most effective means of improving clinician cognition in order to achieve gains in diagnostic reliability are unclear. We propose a tripartite educational agenda for improving diagnostic performance among students, residents and practising physic...

The following incident was submitted to the Emergency Medicine Events Register (EMER – http://www.emer .org.au). EMER is an anonymous, confidential and protected incidentreporting system that is supported by ACEM. Anyone working in emergency medicine can enter a near miss or AE by following the link from the website. It should only take 5 min and will help to inform practice and improve patient...

Diagnostic errors remain an underemphasised and understudied area of patient safety research. We briefly summarise the methods that have been used to conduct research on epidemiology, contributing factors and interventions related to diagnostic error and outline directions for future research. Research methods that have studied epidemiology of diagnostic error provide some estimate on diagnosti...

Considering the advancement of medical sciences, diagnostic tests have been developed to distinguish patients from healthy population. Therefore, Determining and evaluation of the diagnostic accuracy tests is of great importance. The accuracy of a test under evaluation is determined through the amount of agreement between its results with the results of the gold standard, and this test accuracy...

Background: Although cervical malignancy rate had grown up in recent years, primary cervical lymphoma is so rare. It must be high index of suspicious for primary cervical lymphoma diagnosis in patient with malignancy-like signs and symptoms for early detection. Primary cervical lymphoma has no standard treatment or follow-up protocol; so the management still is in doubt and based on previous ca...
