Identifying risk factors for heart disease over time: Overview of 2014 i2b2/UTHealth shared task Track 2

Abstract: The second track of the 2014 i2b2/UTHealth Natural Language Processing shared task focused on identifying medical risk factors related to Coronary Artery Disease (CAD) in the narratives of longitudinal medical records of diabetic patients. The risk factors included hypertension, hyperlipidemia, obesity, smoking status, and family history, as well as diabetes and CAD, and indicators that suggest the presence of those diseases. In addition to identifying the risk factors, this track of the 2014 i2b2/UTHealth sha… Show more

“…Moreover, the DM capacity for treatment of heterogeneous data sources is increasingly adopted. (Stubbs et al, 2015) (Goryachev et al, 2006). We mention here two more examples how text mining delivers useful information about risk factors and adverse drug events.…”

“…To assist decision making, relevant information in such reports needs to be extracted, for which machine learning methods are typically used. This extracted information can be used as input for several applications, such as the identification of diagnostic criteria for heart failure [1, 2] or the prediction of diagnosis and procedure codes [3]. Since the effectiveness of data-driven algorithms not only depends on data size, but also on the quality of data representation, robust information extraction techniques are required [4, 5].…”

“…The second track of the 2014 i2b2/UTHealth shared task [2] hypothesized that, to identify medical risk factors in longitudinal medical records, and in particular to assess the severity of a risk factor, identifying indicators of a disease would be more informative than identifying the actual diagnosis. If hypertension, for instance, can be managed through diet and exercise, it would be considered less severe than when it requires anticoagulants.…”
