Abstract
El estudio evaluó la utilización del puntaje POSSUM (Physiological and Operative Severity Score for Enumeration of Mortality and Morbity) para predecir la mortalidad en la práctica quirúrgica. Fueron analizados 416 pacientes quirúrgicos internados en la UTI para cuidados postoperatorios. Fueron realizadas comparaciones entre las tasas de mortalidad estimada y observada, de acuerdo con 4 grupos de riesgo: 0-4%, 5-14%, 15-49%, 50% o más, y calculada el área debajo de la curva ROC del puntaje POSSUM y APACHE II para la mortalidad. La tasa de mortalidad fue de 2,4%. Los puntajes POSSUM y APACHE II superestimaron el riesgo de muerte, y el área debajo de la curva ROC del POSSUM fue de 0,762 y la del APACHE II de 0,737, lo que sugiere la utilización del POSSUM como herramienta auxiliar en la predicción de riesgo de muerte en pacientes quirúrgicos.
This study evaluated the use of the POSSUM (Physiological and Operative Severity Score for Enumeration of Mortality and Morbidity) score for predicting mortality in surgical practice. In this study, 416 surgical patients admitted into ICUs for post-surgical care were analyzed. Both predicted and actual mortality rates were compared, according to four risk groups: 0-4%, 5-14%, 15-49%, 50% and over, and the area under the ROC curve of the POSSUM and APACHE II for mortality. The POSSUM and APACHE II scores overestimated the risk of death. The area under the ROC curve of the POSSUM was 0.762, and under APACHE II was 0.737, suggesting the use of POSSUM as an auxiliary tool to predict the risk of death in surgical patients.
