"Indirect Identifiers" means elements in documents and records that increase the likelihood of identifying an individual, but do not involve direct identifiers.

"Individually Identifiable Health Data" means any health data that can be used to identify the individual supplying or described in the health data.  Specifically included are data elements, alone or in combination with other elements in the health data, containing unique patient or individual provider identifiers.  Any health data pertaining to fewer than six individual providers at any single identifiable health facility constitutes individually identifiable health data.


"Individually Identifiable Health Information" means information that:


is a subset of individually identifiable health data that is created or received by the Department;


relates to the past, present or future physical or mental health or condition of an individual, the provision of health care to an individual, or the past, present or future payment for the provision of health care to an individual; and

"Patient" means an individual who receives health care from an individual provider or who receives care while in a health facility; this includes residents of licensed long-term care facilities.


"Privacy Rule" means the Health Insurance Portability and Accountability Act regulations.


"Public Use Health Data File" means a Department health data file designated as de-identified by the IRB that is available to anyone. Health data elements are limited and health data values are aggregated in the files so that the proportion of unique records is below thresholds as determined by the IRB and consistent with common practice for developing the files.


"Safe Harbor De-identification Method" means a method of de-identification so that the Department staff member who discloses the de-identified information does not have actual knowledge that the information could be used alone or in combination with other information to identify an individual who is the subject of the information, and that the 18 HIPAA identifiers of the individual, or of relatives, employers or household members, are removed.


"Statistical De-identification" means that, upon the request of the Department, a qualified statistician using accepted analytic techniques concludes that the risk is very small that the individual level health data could be used alone or in combination with other reasonably available information to identify the subject of the health data.  For the purposes of this procedure, a qualified statistician shall be a member of the Department's staff who is identified by the IRB for this purpose.
