Prediction of in-hospital mortality ofClostriodiodes difficileinfection using critical care database: a big data-driven, machine learning approach

Abstract: Research objectivesClostriodiodes difficile infection (CDI) is a major cause of healthcare-associated diarrhoea with high mortality. There is a lack of validated predictors for severe outcomes in CDI. The aim of this study is to derive and validate a clinical prediction tool for CDI in-hospital mortality using a large critical care database.MethodologyThe demographics, clinical parameters, laboratory results and mortality of CDI were extracted from the Medical Information Mart for Intensive Care-III (MIMIC-III… Show more

“…In the study conducted by Ruzicika et al, which focused on predicting CDI recurrence and mortality, the XGBoost ML technique yielded AUROC scores of 0.65 and 0.69, which was similar to LR AUROC scores of 0.63 and 0.68 in the training data set ( 31 ). Similarly, in another study by Du et al, for predicting primary CDI, the AUROC for LR was 0.69, whereas random forest algorithm achieved AUROC of 0.71 and gradient boosting reached 0.72 ( 19 ). Additional information about the various ML models used, and their corresponding AUROC values can be found in Table 3 .…”

“…We identified a total of 1,290 unique citations by our search strategy and 195 after screening of full text. Eventually, a total of 12 studies ( 19 , 28 38 ) were included. There was near-perfect agreement between the 2 reviewers (S.M., R.T.) in the inclusion of studies (Cohen k: 0.977, 95% confidence interval: 0.81–1.00).…”
