DASIS Program Description
The Drug and Alcohol Services Information System (DASIS) is the primary source of national information on the services available for substance abuse treatment and the characteristics of individuals admitted to treatment. DASIS contains three data sets which are maintained with the cooperation and support of the States:
Inventory of Behavioral Health Services (I-BHS) - The I-BHS is a master list of organized substance abuse treatment programs known to SAMHSA. State substance abuse agencies assist in maintaining the I-BHS by informing SAMHSA of the facilities they license, certify or otherwise recognize. In addition, the I-BHS includes some facilities identified from other sources, mostly hospital-based or private-for-profit substance abuse treatment programs. The I-BHS is used as the list frame for the annual National Survey of Substance Abuse Treatment Services (N-SSATS) and as a sampling frame for other special surveys of treatment providers and their clients.
Treatment Episode Data Set (TEDS) - The TEDS is a minimum data set of demographic and drug history information about individuals admitted to treatment, primarily by providers receiving public funding. States extract these data from their administrative data systems and transmit them to SAMHSA on a regular basis. The TEDS includes data collected at admission and at discharge, maintained as two separate but linkable data sets. Recently, several new data elements were added to the TEDS data set to provide National Outcome Measures (NOMS). Nearly all states are currently providing the TEDS admission and discharge data (including the NOMS data elements). States not currently submitting both admission and discharge data are expected to begin submitting complete TEDS data in the near future.
National Survey of Substance Abuse Treatment Services (N-SSATS) - The N-SSATS (formerly the Uniform Facility Data Set) is an annual census of all treatment facilities listed on the I-BHS. Information is collected on the location, organization, structure, services, and utilization of substance abuse treatment facilities in the United States. The data are used for program administration and policy analysis. Information from the survey is also used to compile and update the National Directory of Drug and Alcohol Abuse Treatment Programs and the on-line Substance Abuse Treatment Services Locator, two widely used resources for referrals to treatment.
National Mental Health Services Survey (N-MHSS) - N-MHSS is an annual survey of all mental health treatment facilities listed on the I-BHS. Information is collected on the location, organization, structure, services, and utilization of mental health treatment facilities in the United States and U.S. jurisdictions. Information from the survey is used to update the Behavioral Health Treatment Services Locator, a widely used resource for referrals to treatment.
