Abstract
ResumenLas escalas de severidad aplicadas en unidades de cuidados intensivos son herramientas de gran utilidad para determinar la magnitud de una condición clínica y de esta manera establecer el pronóstico del paciente. Sin embargo, no deben ser utilizadas para determinar criterios de admisión a estas unidades y, mucho menos, para de acuerdo al puntaje obtenido, tomar conductas diagnósticas y terapéuticas sin base en estudios clínicos. A través del tiempo, los cambios de las características de los pacientes ingresados en las unidades de cuidados intensivos junto con las nuevas tendencias diagnósticas y terapéuticas han hecho que las escalas mas utilizadas sobreestimen la probabilidad de muerte de los pacientes admitidos. Es por ello, que a medida que esto ocurra las escalas deben ser sometidas a intervenciones con el fin de actualizarlas sin que pierdan validez y eficacia. El objetivo de este artículo es brindarle el conocimiento básico y actualizado para la implementación de las escalas mas aplicadas en la mayoría de las unidades de cuidados intensivos. (Duazary 2009 I; 71-75)AbstractScales of severity applied in intensive care units are tools very useful to determine magnitude of a clinical condition and to establish prognosis of the patient. Nevertheless they don´t have to be used to determine criteria of admission to these units, much less according to the obtained score, to take diagnostic and therapeutic conducts without base to clinical studies. Through time, the changes of the characteristics of patients entered the intensive care units along with the new diagnostic and therapeutic tendencies have done that the more used scales overestimate probability of death of the admitted patients. For this reason, in proportion to this happens the scales must be put under interventions to update them without they lose validity and effectiveness.The objective of this article is to offer you the basic and updated knowledge for the implementation of the more applied scales in the majority of the intensive care units.Key words: Prognosis; severity; scale; variable; calibration; discrimination; MPM; APACHE.References
