The 2014 i2b2/UTHealth challenge consists of two traditional NLP tracks:

Track 1: De-identification: Removing protected health information (PHI) is a critical step in making medical records accessible to more people, yet it is a very difficult and nuanced task. This track addresses the problem of de-identifying medical records over a new set of over 1300 patient records, with surrogate PHI for participants to identify.

Track 2: Identifying risk factors for heart disease over time: Medical records for diabetic patients contain information about heart disease risk factors such as high blood pressure and cholesterol levels, obesity, smoking status, etc. This track aims to identify the information that is medically relevant to identifying heart disease risk, and track their progression over sets of longitudinal patient records.

The data for this task is provided by Partners HealthCare. All records have been fully de-identified and manually annotated for risk factors related to diabetes and heart disease risk factors.

Data for the challenge is released under a Rules of Conduct and Data Use Agreement. Obtaining the data requires completing a registration (https://i2b2.org/NLP/HeartDisease/Register.php).
