Treatment Episode Data Set: Admissions (TEDS-A) Client-Level Substance Use Data: Admissions
TEDS-A is a national data system of annual admissions to substance use treatment facilities. A sibling data system—Treatment Episode Data Set: Discharges (TEDS-D)—collects data on discharges.
TEDS-A contains records on admissions of people aged 12 and older, and includes information on admission demographics (for example, age, sex, race/ethnicity, employment status) and substance use characteristics (for example, substances used, age at first use, route of use, frequency of use, number of prior admissions). TEDS-A records represent admissions rather than individuals, as a person may be admitted to treatment more than once.

Scope and Methodology Notes
Geographic Coverage: United States and jurisdictions
Unit of Observation: Treatment Admissions or Discharges
Data Types: Administrative Records Data
Universe: Admissions (for TEDS-A) or Discharges (for TEDS-D) that were received and processed in the calendar year
Several limitations to the data exist:
The TEDS system is admission-based; therefore, TEDS admissions and discharges do not represent individuals. For example, an individual admitted to and discharged from treatment twice within a calendar year would be counted as two admissions and two discharges.
The primary, secondary, and tertiary substances of misuse reported to TEDS are those substances that led to the treatment episode. This reporting does not necessarily account for all drugs used at the time of admission.
The way an admission is defined may vary from state to state, such that the absolute number of admissions is not a valid measure for comparing states.
States continually review the quality of their data processing. As states identify systematic errors, historical TEDS data files may be revised. While this process improves the data set over time, reported historical statistics may change slightly from year to year.
States vary in the extent to which coercion plays a role in referral to treatment. This variation derives from criminal justice practices and differing concentrations of substance-using subpopulations.
Public funding constraints may direct states to selectively target special populations, for example, pregnant women or adolescents.
Some states have no opioid treatment programs (OTPs) that provide medication-assisted therapy using methadone, buprenorphine, or naltrexone.
TEDS provides demographic, clinical, and substance use characteristics of admissions to alcohol or drug treatment in facilities that report to state administrative data systems. The unit of analysis is treatment admissions to state-licensed or certified substance use treatment centers that receive federal public funding.
TEDS has two parts: a minimum data set and a supplemental data set. All states provide a minimum data set, and some states provide a supplemental data set. The minimum data set consists of 19 items that include:
Primary, secondary, and tertiary substances used by the subject and their route of administration; frequency of substance use, and age at first use
Source of referral to treatment
Number of prior treatment episodes
Service type, including planned use of OTPs providing medication-assisted therapy using methadone, buprenorphine or naltrexone
