Abstract

Objectives: To compare emergency department (ED) visit rates for suicidal ideation and/or self-harm among youth by urban-rural location of residence.

Study design: This is a retrospective analysis of ED visits for suicidal ideation and/or self-harm by youths aged 5-19 years (n = 297 640) in the 2016 Nationwide Emergency Department Sample, a representative sample of all US ED visits. We used weighted Poisson generalized linear models to compare population-based visit rates by urban-rural location of patient residence, adjusted for age, sex, and US Census region. For self-harm visits, we compared injury mechanisms by urban-rural location.

Results: Among patients with ED visits for suicidal ideation and/or self-harm, the median age was 16 years, 65.9% were female, 15.9% had a rural location of patient residence, and 0.1% resulted in mortality. The adjusted ED visit rate for suicidal ideation/or and self-harm did not differ significantly by urban-rural location. For the subset of visits for self-harm, the adjusted visit rate was significantly higher in small metropolitan (adjusted incidence rate ratio [aIRR], 1.39; 95% CI, 1.01-1.90), micropolitan (aIRR, 1.46; 95% CI, 1.10-1.93), and noncore areas (aIRR, 1.39; 95% CI, 1.03-1.87) compared with large metropolitan areas. When stratified by injury mechanism, ED visit rates for self-inflicted firearm injuries were higher among youths living in rural areas compared with those in urban areas (aIRR, 3.03; 95% CI, 1.32-6.74).

Conclusions: Compared with youths living in urban areas, youths living in rural areas had higher ED visit rates for self-harm, including self-inflicted firearm injuries. Preventive approaches for self-harm based in community and ED settings might help address these differences.
