Retrospective Evaluation Of The Accuracy Of Five Different Severity Scores To Predict The Mortality In Burns Patients

Abstract

Abstract Background Patients with great clinical impairment, due to extensive burns, need to be admitted to intensive care units, in these treatment sites, indices are used to classify the severity of patients. The aim of the study was to compare the accuracy of the FLAMES score in relation to the Acute Physiologic and Chronic Health Evaluation II (APACHE II), the Simplified Acute Physiologic Score II (SAPS II), the Logistic Organ Dysfunction System (LODS) and the Abbreviated Burn Severity Index (ABSI) applied to the severe burn patient facing mortality in an ICU of a reference center for burns in Brazil. Methods A retrospective study conducted in ICU comparing the accuracy the APACHE II, SAPS II, LODS, ABSI and FLAMES instruments were applied to all the selected medical records. To evaluate the accuracy of the SIs, the Receiver Operating Characteristic curve was calculated and the area under the curve (AUC). Results Among the 574 patients included in the study, male individuals (70.13%), with an average age of 44.01 ± 28.64 prevailed and the majority of the burns were caused by accidents (76.53%). The outcome accounted for 35.29% of deaths. It was observed that the FLAMES and ABSI presented the two largest areas under the ROC curves and the highest sensitivities (96% and 89%, respectively). The APACHE II, SAPS II and LODS presented sensitivities equal to or greater than 80%. Conclusions It has been demonstrated that indices specifically developed for burn patients, specifically the FLAMES and ABSI indices, presented better accuracies and prediction performances.
