Self-harm presentations to emergency departments (ED) have become a growing concern, yet little is known about self-harm visits in pediatric EDs. This study aimed to investigate the clinical and demographic characteristics of patients who presented to the pediatric ED between 2012 and 2017 with non-suicidal self-harm (NSSH, n = 63, 60.3% female, M = 14.25 years), suicidal ideation (SI, n = 75, 57.3% female, M = 14.83 years), and suicide attempts (SA, n = 461, 82.9% female, M = 15.41 years). Also, predictors of SA were investigated. Of the patients, 79.4% had at least a psychiatric disorder. Depression was the most common diagnosis in the SI and SA groups, and autism spectrum disorder and intellectual disability were the leading diagnoses in the NSSH group. Self-poisoning was the most common method, and older age, female sex, having relational problems, and prior or current psychiatric admissions were the most important predictive factors of SA. NSSH, SI, and SA exhibit different features in early life. EDs provide an important opportunity for initiating developmentally appropriate interventions to reduce future risks.

急诊科 (ED) 的自我伤害介绍已成为越来越受关注的问题，但对儿科急诊科的自我伤害就诊知之甚少。本研究旨在调查 2012 年至 2017 年间在儿科 ED 就诊的非自杀性自残（NSSH，n = 63，60.3% 女性，M  = 14.25 岁）、有自杀意念（SI , n = 75, 57.3% 女性, M  = 14.83 岁), 和自杀未遂 (SA, n = 461, 82.9% 女性, M = 15.41 年）。此外，还研究了 SA 的预测因素。在这些患者中，79.4% 的患者至少患有精神疾病。抑郁症是 SI 和 SA 组最常见的诊断，而自闭症谱系障碍和智力障碍是 NSSH 组的主要诊断。自我中毒是最常见的方法，年龄较大、女性、有关系问题以及之前或现在的精神病院入院是 SA 最重要的预测因素。NSSH、SI 和 SA 在生命早期表现出不同的特征。急诊科为启动适合发育的干预措施以降低未来风险提供了重要机会。
