King CA, et al. - Predictive factors of suicide attempts within 3 months of an emergency department (ED) visit were determined. From 13 pediatric EDs (Pediatric Emergency Care Applied Research Network) and one Indian Health Service Hospital in the United States, researchers approached 10,664 patients; of these, they enrolled and surveyed 6,448 (60%) for suicide risk. A subset of 2,104 participants completed the 3-month telephone follow-up; of these, 104 adolescents (4.9%) made a suicide attempt between enrollment and 3-month follow-up. Subgroups of adolescents defined by sex and if they reported recent suicidal thoughts differed in the key risk factors for adolescent suicide attempts. For the full sample, the final multivariable model incorporated the presence of suicidal ideation during the past week, lifetime severity of suicidal ideation, lifetime history of suicidal behavior, and school connectedness. The final model incorporated only lifetime severity of suicidal ideation and social connectedness for the subgroup of adolescents not conveying recent suicidal ideation at baseline. Only lifetime severity of suicidal ideation and past week suicidal ideation were included in the final model for males. Past week suicidal ideation, lifetime severity of suicidal ideation, number of past-year nonsuicidal self-injury incidents, and social connectedness were included in the final model for females.
