Some commonly used indicators are severity-of-disease classification systems as APACHE (Acute Physiology and Chronic Health Evaluation), SAPS (Simplified Acute Physiology Score), MPM (Mortality Prediction Model), OASIS (Oxford Acute Severity of Illness Score), SOFA (Sequential Organ Failure Assessment), among others<a class="elsevierStyleCrossRef" href="#bib0185"><span class="elsevierStyleSup">1</span></a>; in general, there is a score that increases with the risk of patient mortality. These classification systems are used to determine the risk in population studies conducted in an ICU, and provide a method for benchmarking between intensive care units of different hospitals. However, these indicators lack the precision required for use at individual level, they present significant errors at patient data away from the average. For this reason, efforts have been made to increase the performance of these indicators through the use of computational techniques such as machine learning; in recent years, specific models according to groups of patients that shares a common characteristic (like diagnostics, service type or a similarity metric) have been created.<a class="elsevierStyleCrossRefs" href="#bib0190"><span class="elsevierStyleSup">2,3</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">Sepsis is a life-threatening organ dysfunction due to a dysregulated host response to infection.

The SGB algorithm involves a parameter-tuning process. the three main parameters are: <span class="elsevierStyleItalic">M</span>, the number of trees that are aggregated in the model; <span class="elsevierStyleItalic">ν</span>, the learning rate that helps to control over-fitting by controlling the gradient steps and <span class="elsevierStyleItalic">L</span>, the number of splits performed on each Tree.<a class="elsevierStyleCrossRefs" href="#bib0310"><span class="elsevierStyleSup">26–28</span></a> Least Absolute Shrinkage and Selection Operator (LASSO),<a class="elsevierStyleCrossRef" href="#bib0325"><span class="elsevierStyleSup">29</span></a> is a regression analysis method that performs both variable selection and regularization in order to enhance the prediction accuracy and interpretability of the statistical model. LASSO puts a constraint on the sum of the absolute values of the model parameters, applying a regularization process where it penalizes the coefficients of the regression variables and set some of them exactly to zero. In practice there is tuning parameter <span class="elsevierStyleItalic">λ</span>, that controls the controls the amount of shrinkage that is applied to the estimates. The SGB and LASSO models were implemented with R-packages.<a class="elsevierStyleCrossRefs" href="#bib0330"><span class="elsevierStyleSup">30–32</span></a> A detailed description of the used methodologies and the parameters tuning process is found in the supplementary material.</p><p id="par0100" class="elsevierStylePara elsevierViewall">After the predictors were selected with both methods five SGB models were developed, two with the predictors selected with each of the methods, one with the intersection of the predictors, one with the union of the predictors and one with all the predictors. To assess performance in the five SGB models developed with the different sets of predictors and the three severity-of-disease classification systems (SOFA, SAPS II and OASIS) we calculate the Area Under an ROC Curve (AUROC) using the PRROC R package.<a class="elsevierStyleCrossRef" href="#bib0345"><span class="elsevierStyleSup">33</span></a> This was repeated for 5000 random samples of size 320 to generate the distributions of metrics shown in a comparison boxplot.

Accuracy and AUROC analysis also ratify the complex interdependence among different physiological systems in response to sepsis, because the SGB models are composed of between 450 and 1150 trees, which are difficult to interpret; therefore, it is necessary to develop easy-to-use computer tools that allow these types of models to be implemented within the ICU. This study indicates that it is possible to generate a specific model for the prediction of mortality of patients admitted to an ICU with a diagnosis of sepsis, that includes variables that are now commonly evaluated and been widely used.</p><p id="par0135" class="elsevierStylePara elsevierViewall">SGB variable importance and LASSO methodologies allowed to develop models that preserve the same performance as the one generated with all the predictors but with less predictors. Also the intersection of the predictors selected by the two methods leads to the development of a much simpler model with only 18 predictors and less trees, which also presents good performance.</p><p id="par0140" class="elsevierStylePara elsevierViewall">As expected, older patients are at greater risk in consequence the most important parameter for the outcome is the age. Urine output is used as a marker of acute kidney injury, a disease that is associated with substantial in-hospital mortality, beside this, it is important to note that it is a relatively simple and widely used variable in the ICU that has a high relevance in predicting 1-year mortality with the SGB methodology.</p><p id="par0145" class="elsevierStylePara elsevierViewall">Minimum lactate over the first 24<span class="elsevierStyleHsp" style=""></span>h of the ICU admission is the ninth most important variable for the outcome prediction in this study; Lactate is currently used within the ICU as a diagnostic tool and as a prognostic marker, since the higher the value, the greater the risk of mortality. However, if the lactate of a patient does not reach below a threshold, it will also have a higher mortality risk. For this reason, the minimum lactate during the first 24<span class="elsevierStyleHsp" style=""></span>h must also be analyzed in ICUs. Mean lactate is also considered an important predictor, which agrees with what is reported in the literature, since hyperlactatemia is related with a poor outcome in ICU.<a class="elsevierStyleCrossRef" href="#bib0350"><span class="elsevierStyleSup">34</span></a> An elevated blood urea nitrogen (BUN) is associated with increased mortality in critically ill patients.<a class="elsevierStyleCrossRef" href="#bib0355"><span class="elsevierStyleSup">35</span></a></p><p id="par0150" class="elsevierStylePara elsevierViewall">The main objective of this work is to present a model for the 1-year mortality prediction of the patients that are admitted in a ICU with a sepsis diagnosis; and shows that the use of ensemble based algorithms (SGB in this study) and the inclusion of statistical descriptors that are not usually taken into account in the traditional severity-of-disease classification systems (for example mean, minimum and maximum values of the same variable), improves the performance of the prediction of prognosis models in patients admitted to an ICU with diagnosis of sepsis, however, this means that the model can only be used after the first 24<span class="elsevierStyleHsp" style=""></span>h of observation.</p><p id="par0155" class="elsevierStylePara elsevierViewall">Other limitations of this study include the fact that it is based on the data taken at only one institution, however, despite the limitation of being single-centered, the main advantages of MIMIC-III are that, right now, it is the only freely accessible critical care database of its kind, the dataset spans more than a decade and it has detailed information about individual patient care that includes time-stamped nurse-verified physiological measurements. For this reasons MIMIC-III (and specially it previous version MIMIC-II) are widely used internationally. For this study in particular, an important advantage is that besides in-hospital mortality, MIMIC-III provides Out-of-hospital mortality dates through the Social Security Administration Death Master File. On the other hand, there have been few validated methods of medical record data extraction for estimating sepsis, particularly in this work, the Angus criteria was used, which is one of the first protocols using administrative data, and was validated by comparing a nurse-driven identification of a population of patients with the clinical syndrome of sepsis, however, Angus criteria has shown to be capable of capture most of the patients with severe sepsis but not exclusively and cohorts identified by different methodologies (for instances Angus criteria and Martin Criteria) yielded widely different patient groups.<a class="elsevierStyleCrossRef" href="#bib0360"><span class="elsevierStyleSup">36</span></a></p><p id="par0205" class="elsevierStylePara elsevierViewall">It is also important to note that the criteria used to select patients is based on the ICD codes, which in MIMIC-III are generated for billing purposes at the end of the hospital stay, hence it does not guarantee that patients suffer from sepsis at the time of admission, even so, we evaluate the data of the first 24 hours after admission since we considered that the majority of patients are usually already infected at ICU admission.</p><p id="par0160" class="elsevierStylePara elsevierViewall">The emergence of machine learning techniques in the field of health is a fact. Specifically, in the field of Intensive Care, it is undeniable that the potential for its application is immense. Specifically, the use of assembly algorithms, and in particular the SGB, allows the development of prediction models, which despite being complex show significantly better discrimination than traditional severity of disease scores (Like OASIS, SAPS II or SOFA). This could be explained by the fact that the base models in the SGB algorithm are not fitted independently, but sequentially, this mean that the subsequent predictors are based on the results of previous predictors, moreover, SGB is based on a steepest gradient algorithm which places emphasis on misclassified training data that are close to their correct classification, which reduces the number of misclassified observations and facilitates mortality prediction models to be used at the individual level.</p></span><span id="sec0045" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0125">Author's contribution</span><p id="par0165" class="elsevierStylePara elsevierViewall">Javier E.
