Youth-Nominated Support Team Intervention for Suicidal Adolescents–Version II (YST) intervention for suicidal adolescents is associated with reduced mortality, according to a recent study. This post hoc secondary analysis of a randomized clinical trial used National Death Index (NDI) data from adolescent psychiatric inpatients from 2 US psychiatric hospitals enrolled in the clinical trial from November 10, 2002, to October 26, 2005. Eligible participants were aged 13 to 17 years and presented with suicidal ideation, a suicide attempt, or both within the past 4 weeks. Participants were randomized to receive treatment as usual (TAU) or YST plus TAU (YST). The length of NDI follow-up ranged from 11.2 to 14.1 years. Analyses were conducted between February 12, 2018, and September 18, 2018. Researchers found:

• NDI records were reviewed for all 448 YST study participants (319 [71.2%] identified as female; mean [SD] age, 15.6 [1.3] years; 375 [83.7%] of white race/ethnicity).
• There were 13 deaths in the TAU group and 2 deaths in the YST group (hazard ratio, 6.62).
• No patients were withdrawn from YST owing to adverse effects.
