Protecting Confidentiality in The Treatment Episode Data Set (TEDS)

The DASIS Report:  Protecting Confidentiality in TEDS

• HTML format

• PDF format

Highlights:

• TEDS is an annual administrative data system that provides descriptive information about admissions to specialty providers of substance abuse treatment.  Routinely, measures are applied to maintain the confidentiality of the admission records.

• Routine confidentiality protection measures include removing direct identifiers  and applying disclosure analysis; both methods help remove the uniqueness of individual records within a file and thereby help prevent the identification of any individual.

• Disclosure analysis involves the careful examination of a data file for indirect identifiers (such as gender, education, race, and income) that could be used in combination to attempt to identify (i.e., disclose) a respondent.  Furthermore, disclosure analysis allows dissemination of a public use file that is effective for most analytic purposes while protecting the confidentiality of the admissions.

• Persons wanting to do their own data analysis might find  OAS's data systems  helpful as well as background and other information on SAMHSA's data analysis system (SAMHDA).
