Treatment Episode Data Set (TEDS)

About TEDS

Details 

When undergoing substance abuse treatment, individual people can be admitted and discharged from treatment multiple times. The Treatment Episode Data Set (TEDS) system comprises demographic and drug history information about these individuals. 

TEDS-A records the admissions, and TEDS-D records the discharges. The two datasets are separate but linkable. TEDS-A data collection began in 1992, and TEDS-D began in 2000. These datasets include:

  • Data for individuals who are 12 years old or older
  • Records for an admission or discharge, not for individual people
  • Demographic information, such as age, sex, race/ethnicity, and employment status
  • Substance use characteristics, such as substances used, age at first use, route of use, frequency of use, and number of previous admissions 

Where Does the Data Come From? 

Information on admissions to and discharges from substance use treatment services are collected through state administrative systems and then reported to SAMHSA by the Single State Agencies (SSAs). Currently, TEDS data are reported by SSAs from all 50 states, the District of Columbia, and Puerto Rico. 

Many of the facilities that report TEDS data receive state funds or federal block grant funds. To provide alcohol and drug treatment services. State laws require substance abuse treatment programs to report publicly funded admissions. Some states only collect data on publicly funded admissions. Other states can collect privately funded admissions from facilities that receive public funding. States then report the data from their state administrative systems to SAMHSA.
