Abstract

Despite eradication efforts, Methicillin-resistant Staphylococcus aureus (MRSA) remains a common cause of serious hospital-acquired infections (HAI) in the United States. Electronic Health Record (EHR) systems capture MRSA infection events along with detailed patient information preceding diagnosis. In this work, we design and apply machine learning methods to support early recognition of MRSA infection by estimating risk at several time points during hospitalization. We use EHR data including on-admission and throughout-stay patient information. On-admission features capture clinical and non-clinical information while throughout-stay features include vital signs, medications, laboratory studies, and other clinical assessments. We evaluate prediction accuracy achieved by core Machine Learning methods, namely Logistic Regression, Support Vector Machine, and Random Forest classifiers, when mining these different types of EHR features to detect patterns predictive of MRSA infection. We evaluate classification performance using MIMIC III – a critical care data set comprised of 12 years of patient records from the Beth Israel Deaconess Medical Center Intensive Care Unit in Boston, MA. Our methods can achieve near-perfect MRSA prediction accuracies one day before documented clinical diagnosis. Also, they perform well for early MRSA prediction many days in advance of diagnosis. These findings underscore the potential clinical applicability of machine learning techniques.
