Resumen

WAINSTEIN, Eduardo. The heuristics of reaching a diagnosis. Rev. méd. Chile [online]. 2009, vol.137, n.12, pp.1636-1641. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872009001200014.

Making a diagnosis in medicine is a complex process in which many cognitive and psychological issues are involved. After the first encounter with the patient, an unconscious process ensues to suspect the presence of a particular disease. Usually, complementary tests are requested to confirm the clinical suspicion. The interpretation of requested tests can be biased by the clinical diagnosis that was considered in the first encounter with the patient. The awareness of these sources of error is essential in the interpretation of the findings that will eventually lead to a final diagnosis. This article discusses some aspects of the heuristics involved in the adjudication of priory probabilities and provides a brief review of current concepts of the reasoning process.
