A record in which identifying information is removed. Under the HIPAA Privacy Rule, data are de-identified if either: an experienced expert determines that the risk that certain information could be used to identify an individual is “very small” and documents and justifies the determination, or the data do not include any of the 18 identifiers (of the individual or his/her relatives, household members, or employers) which could be used alone or in combination with other information to identify the subject. Note that even if these identifiers are removed, the Privacy Rule states that information will be considered identifiable if the covered entity knows that the identity of the person may still be determined. – UCSB IRB
