Announcements

The Office of Population Surveys has released the infographic-style report: Behavioral health among older adults: Results from the 2021 and 2022 National Surveys on Drug Use and Health. This report presents key substance use, mental health, and treatment indicators among adults aged 60 or older in the United States, by gender.

Mental Health Client-Level Data (MH-CLD) 2022: Data on Clients Receiving Mental Health Treatment Services Through State Mental Health Agencies annual report presents client demographics, National Outcome Measures (NOMs), and the top five mental health diagnoses by geographic distribution in 2022, in addition to the client demographics and the top five mental health diagnoses in 2018-2022.

The Office of Treatment Services is thrilled to announce the launch of the 2024 National Substance Use and Mental Health Services Survey (N-SUMHSS)!

N-SUMHSS is the most comprehensive national source of data on treatment services provided by substance use and mental health treatment facilities in the United States. Specifically, the survey collects data on the location, characteristics, and utilization of substance use and mental health treatment facilities. N-SUMHSS is a voluntary facility survey and over 20,000 facilities participated in 2023. We are pleased to announce that in addition to the main N-SUMHSS, two survey supplements will be implemented during the 2024 cycle: the Veterans Affairs (VA) Supplement and the Electronic Health Record (EHR) Supplement.

This annual N-SUMHSS survey is a critical tool used to populate SAMHSA’s FindTreatment.gov, a publicly searchable, and user-friendly website designed for all Americans seeking treatment facilities for substance use and/or mental disorders for themselves, family members, or loved ones.

The 2024 N-SUMHSS will be open until early December of 2024. We look forward to this new survey cycle and the valuable information N-SUMHSS continues to provide.
