RESULTS
Diagnostic Errors : After the peer audit, 33 diagnostic errors were identified in the 371 recorded cases (9.97%).
Use of heuristics: First, with respect to representativeness, the first diagnostic impression (FDI) coincides with the confirmation diagnosis (CD) in 183 of the cases (49.59%); in the other half of the cases there is no such agreement. This result means that in almost half of the cases the doctors use the representativeness heuristic in the diagnostic decision process.
In the case of availability, the final or confirmation diagnosis coincides with one of the differential diagnoses in 304 of the registered cases, which represents 82.38%. In most cases, the physician determined as a final diagnosis one of the three that appeared most quickly in his mind (DD), being this concordance a sample of the use of the availability heuristic.
Finally, in the overconfidence, in 54 of the cases (14.52%) the doctors felt with a confidence in their diagnostic judgment below 50%. In 103 cases (27.69%) the confidence was between 50 and 70%. Finally, in 214 cases (57.80%) the doctors showed an above-average confidence in their diagnostic judgment (more than 75.17%). This result shows that in more than half of the cases the doctors showed above-average confidence. (Fig.2)
