n2c2 2014 De-identification

The first of these was the de-identification track focused on identifying protected health information (PHI) in longitudinal clinical narratives. TRACK 1: NER PHI\n HIPAA requires that patient medical records have all identifying information removed in order to protect patient privacy.

There are 18 categories of Protected Health Information (PHI) identifiers of the patient or of relatives, employers, or household members of the patient that must be removed in order for a file to be considered de-identified. In order to de-identify the records, each file has PHI marked up. All PHI has an XML tag indicating its category and type, where applicable.
