Abstract

ResumenEn los programas de diagnóstico precoz, se considera sobrediagnóstico al diagnóstico de una enfermedad que sin cribado nunca se hubiera diagnosticado, y como se espera que dicho diagnóstico no cause la muerte, se trata innecesariamente. El sobrediagnóstico es un sesgo del propio cribado y un efecto no deseado de la prevención secundaria y de la mejora de la sensibilidad de las técnicas diagnósticas. A priori es difícil de discriminar qué diagnósticos son los clínicamente relevantes y en cuáles se podría evitar el tratamiento. Para minimizar el efecto de sobrediagnóstico, el cribado debe dirigirse a población considerada de riesgo.

In screening programs, overdiagnosis is defined as the detection of a disease that would have gone undetected without screening when that disease would not have resulted in morbimortality and was treated unnecessarily. Overdiagnosis is a bias inherent in screening and an undesired effect of secondary prevention and improved sensitivity of diagnostic techniques. It is difficult to discriminate a priori between clinically relevant diagnoses and those in which treatment is unnecessary. To minimize the effects of overdiagnosis, screening should be done in patients at risk.
