Discovering the insights to be found in textual narrative requires a special approach…an approach which not only protects patient privacy but preserves the narrative integrity of the record, allowing access to the patient ‘story' and the thought process of clinicians.
Since its launch in 2004, De-IDTM software is a leading commercial technology to protect patient privacy through automated HIPAA compliant de-identification of free text in clinical notes and other unstructured medical records and reports. De-ID has supported HIPAA-compliant research and discovery programs for the Federal government, major academic medical centers and health systems, transcription and computer-assisted coding companies and consulting companies by removing “protected health information” (PHI) from discharge summaries, pathology reports, surgical/procedure and radiology notes and free text fields in electronic health record systems under HIPAA compliance programs utilizing both the Safe Harbor and ‘expert determination’ methods.
De-ID seamlessly integrates into data management workflows, using advanced heuristics, lexical and syntactic context analysis to ‘read’ the text, identify PHI from non-PHI in narrative and create a separate, de-identified version of a note or text field. De-ID retains the narrative integrity of the patients story by replacing PHI with proxies (e.g., NAME; PLACE; offset dates). The software understands words in context, and can differentiate between when nouns are used as clinical terms (e.g., Hodgkins Disease: not PHI) and as names (e.g., Dr. Hodgkins: PHI) and permits client control of inclusion and exclusion rules..
In addition, there are software features that support patient identification via an Honest Broker, a feature than has been used for clinical trial recruitment, and also supports clustering of de-identified records associated with the same patient.
