Valoración de la escala Sap3 como modelo predictor de mortalidad en la unidad de cuidados intensivos del Hospital Vicente Corral Moscoso de Cuenca durante el año año 2013

Abstract

Background.- In the Intensive Care Unit (ICU) is important to know the statistics that tell us mainly mortality, which is categorized in variables such as age, sex, origin, transfer service, etc. Providing an overview of the ICU’s deaths. In addition, it is essential to have objective and standardized indicators that allow categorize patients in terms of severity and mortality prospectively. Objective.- So in our study we have set targets to determine the functionality of the SAPS III (ACUTE Physiology SIMPLIFIED SCORE) model as a predictor of mortality in the ICU. Methodology.- The type of study was SPAS3 rating scale score was determined in 323 patients hospitalized in the ICU of Hospital Vicente Corral Moscoso in 2013, in which the main variables were: age, Reason for admission, Shuttle Service, complications, concomitant diseases, laboratory data, and thus the mortality rate, relating it to the actual mortality was calculated. Results.- An average mortality of 24% corresponding to 50 points in the SAPS3 scale with a standard deviation of ± 12 expected mortality ratio of 1.17 for mortality observed with a sensitivity was obtained (75%), specificity (82%), PPV (52%) and NPV (92%), with an area under the ROC curve of 0.84, these data correspond to cut 32% mortality. Conclusions.- SAPS3 scale represents a good diagnostic tool for the calculation of mortality on admission to the Intensive Care Vicente Corral Moscoso Hospital in Cuenca, surpassing in sensitivity and specificity other scalas used, (APACHE II, SOFA). It has a setting appropriate for South America.
