title: [Influence of the natural history of disease on a previous diagnosis in patients with gout].
abstract: The clinical diagnosis of gout can be quite precise in clinically typical forms. However, in chronic or atypical forms, such precision tends to be diminished in clinical practice. A cohort of 248 patients with a diagnosis of urate crystal arthropathy was studied, sent with a definite clinical evaluation, and data such as severity of the disease, joint distribution and the presence of tophi were gathered. Precision data was analyzed with respect to the referral diagnosis according to the severity parameters and the type of physician sending the patient. The best diagnostic precision was seen in the monoarticular forms that were sent both by the emergency room as well as by family physicians, but not in those sent by other specialists. The presence of oligoarticular forms reduced significantly the diagnostic precision in all of the specialties referring patients. The presence of tophi did not improve diagnostic precision. Chronic and severe forms of gout are frequently wrongly evaluated from the clinical standpoint.
