Universe: Facilities across the United States and its territories, including all active treatment facilities on SAMHSA’s Inventory of Substance Use and Mental Health Treatment Facilities (I-TF) and additional facilities provided by state substance use agencies

The N-SUMHSS is a component of SAMHSA’s Behavioral Health Services Information System (BHSIS). The core of BHSIS is the I-TF, a continuously updated, comprehensive listing of all known substance use treatment facilities and mental health treatment facilities.

Facilities in the I-TF fall into two categories:

  • Treatment facilities approved by state substance use and/or mental health agencies: Most facilities in the I-TF are licensed, certified, or otherwise approved by the state substance use and/or mental health agencies to provide substance use and/or mental health treatment.
  • Treatment facilities not approved by state substance use and/or mental health agencies: Since the mid-1990s, SAMHSA has worked to make the I-TF as comprehensive as possible by including treatment facilities that state substance use and/or mental health agencies, for a variety of reasons, do not fund, license, or certify.

As with any data collection effort, limitations must be taken into account when interpreting data from the N-SUMHSS.

  • The N-SUMHSS is a voluntary survey, and while it attempts to obtain responses from all known treatment facilities, some facilities do not respond. The data are not adjusted for facility nonresponse.
  • The N-SUMHSS is a point-prevalence survey. Client counts reported do not represent annual totals. Rather, the N-SUMHSS provides a “snapshot” of substance use and mental health treatment facilities and clients on an average day.
  • Multiple responses are allowed for certain variables (e.g., services provided and specialized programs). Tabulations of these variables include the total number of facilities reporting each response.
