(2005-12-19)Department: Biomedical InformaticsIn biomedical and biological domains, researchers typically study continuous data sets. In these domains, an increasingly popular tool for understanding the relationship between variables is Bayesian network structure ...
-
(2014-07-22)Department: Biomedical InformaticsGene fusions are instances where two discrete genes incorrectly join together. They are common mutations in cancer, and, since the advent of next generation sequencing technology, many gene fusions in cancer tissues have ...
-
(2006-06-07)Department: Biomedical InformaticsPreventive care measures including vaccinations are underutilized. The Emergency Department (ED) environment has been recommended to be a feasible environment to offer pneumococcal vaccination; however, the ED is a challenging ...
-
(2020-07-20)Department: Biomedical InformaticsAsynchronous messaging through the electronic health record (EHR) provides care team members a secure means of communication to reach other care stakeholders, regardless of role or location. Despite reports that communication ...
-
(2022-05-16)Department: Biomedical InformaticsOpioids are commonly prescribed for chronic pain. However, even when titrated appropriately, opioids may result in opioid-related adverse events (OAEs). Previous studies have defined OAEs categorically (e.g., did/did not ...
-
(2012-04-09)Department: Biomedical InformaticsRecord linkage is the task of identifying records from multiple data sources that refer to the same individual. Private record linkage (PRL) is a variant of the task in which data holders wish to perform linkage without ...
-
(2009-07-22)Department: Biomedical InformaticsHealthcare organizations are often stymied in their efforts to prevent insider attacks that violate patient privacy. Numerous high-profile privacy breaches involving celebrities have brought this deficiency to the public's ...
-
(2009-11-09)Department: Biomedical InformaticsThe emergency room is a challenging place to practice medicine. Overcrowding, episodic care, and an interrupt driven environment are all factors contributing to medical errors in the ED . We performed a comprehensive ...
-
(2011-04-16)Department: Biomedical InformaticsMolecular medicine encompasses the application of molecular biology techniques and knowledge to the prevention, diagnosis and treatment of diseases and disorders. Statistical and computational models can predict clinical ...
-
(2018-03-23)Department: Biomedical InformaticsThe Hospital Readmissions Reduction Program (HRRP) permits Centers for Medicare and Medicaid Services (CMS) to reduce reimbursement to hospitals with excess 30-day unplanned readmissions. Diabetes disproportionately impacts ...

(2007-08-03)Department: Biomedical InformaticsThis Masters Thesis project had as its objectives: (1) to provide Vanderbilt University Hospital (VUH) with computerized tools for monitoring microbiological data; (2) to provide the VUH Infection Control Service with tools ...
-
(2014-07-30)Department: Biomedical InformaticsProcess mining corresponds to a collection of methodologies designed to extract knowledge from event logs (e.g., time-stamped events) and provide a description about the underlying processes of a system. Various approaches ...
-
(2008-04-25)Department: Biomedical InformaticsClinical decision support systems can decrease common errors related to inadequate dosing for nephrotoxic or renally cleared drugs. Within the computerized provider order entry (CPOE) system, we developed, implemented, ...
-
(2010-12-06)Department: Biomedical InformaticsThe utilization of clinical decision support (CDS) is increasing among healthcare facilities that have implemented computerized physician order entry or electronic medical records. Formal prospective evaluation of CDS ...
-
(2015-06-25)Department: Biomedical InformaticsNamed entity recognition (NER) is one of the fundamental tasks for building clinical natural language processing (NLP) systems. Machine learning (ML) based approaches can achieve good performance. However, they often require ...
-
(2016-04-09)Department: Biomedical InformaticsUnrecognized adverse drug effects (ADEs) pose a serious clinical problem. They negatively affect patients’ health and quality of life, generate preventable emergency department visits and hospital admissions, and increase ...
-
(2008-12-06)Department: Biomedical InformaticsAlgorithms for discovery of a Markov boundary from data constitute one of the most important recent developments in machine learning, primarily because they offer a principled solution to the variable/feature selection ...
