Treatment Episode Data Set
The Treatment Episode Data Set (TEDS) is an administrative data system providing descriptive information about the national flow of admissions to specialty providers of substance abuse treatment. It is a compilation of data on the demographic and substance abuse characteristics of admissions to (and more recently, on discharges from) substance abuse treatment. The data are routinely collected by State administrative systems and then submitted to the Substance Abuse and Mental Health Services Administration (SAMHSA) in a standard format.
TEDS is comprised of two separate components, the Admissions Data System and the Discharge Data System. The Admissions Data System has two components: a minimum data set that includes demographic and drug history data, and a supplemental data set that includes related data items. Because of the logistics involved in collecting and standardizing admissions and discharge data for an entire calendar year from all the participating States and jurisdictions, there is a delay in the availability of the entire national data set for publication. States vary in their reporting load and the latest year for which they have complete data.
TEDS includes data on almost 2 million admissions reported by over 10,000 facilities to the 50 States, District of Columbia, and Puerto Rico over the 12 month period of a calendar year.
Each record in TEDS documents an admission rather than an individual; persons may be admitted to treatment more than once in a given time period. The number and client mix in TEDS admissions do not represent the total national demand for substance abuse treatment or the prevalence of substance abuse in the general population.
