The Treatment Episode Data Set -- Admissions (TEDS-A) is a national data system of annual admissions to substance abuse treatment facilities. State laws require substance abuse treatment programs to report their publically-funded admissions to the state. Some states collect only their publically-funded admissions while other states are able to collect their privately-funded admissions from facilities that receive public funding. States then report these data from their state administrative systems to SAMHSA. The resulting data system is referred to as TEDS-A. Thus, TEDS does not include all admissions to substance abuse treatment. It does, however, include that portion that would constitute the public burden for substance abuse treatment.
TEDS-A contains records on admissions aged 12 or older, and includes information on admission demographics (age, sex, race/ethnicity, employment status, etc.) and substance abuse characteristics (substances used, age at first use, route of use, frequency of use, number of prior admissions, etc.). TEDS-A records represent admissions rather than individuals, as a person may be admitted to treatment more than once.
A sister data system, called the Treatment Episode Data Set -- Discharges (TEDS-D), collects data on discharges from substance abuse treatment facilities.
