Self-inflicted harm, whether by trauma or drug overdose, is not uncommon, and has important social consequences. This study was a retrospective record analysis of patients who presented to an emergency department after deliberate self-inflicted harm. Over the two-year study period, there were 175 self-inflicted trauma and 441 overdose presentations. The self-inflicted trauma patients were a heterogeneous group and included patients who displayed suicide-related behaviour and behaviour not related to suicide. The self-inflicted traumatic injuries tended to be either relatively minor or potentially very serious. Lacerations to the upper limb were seen most frequently. The trauma and overdose groups were almost mutually exclusive populations and showed some significant differences. The trauma group was smaller, contained a significantly greater proportion of younger patients and males, presented more commonly in the late evening and early morning hours and ultimately received less psychiatric counselling. Research of this type has problems of underreporting and data bias. Prospective studies of self-inflicted trauma would improve the identification of patients after self-harm and improve the understanding of the relationship between the patterns of injury psychiatric diagnosis and the long-term risk of future self-harm.
自我伤害，无论是通过创伤还是药物过量，都并不罕见，且会产生重要的社会后果。本研究是对因故意自我伤害而到急诊科就诊的患者进行的回顾性记录分析。在为期两年的研究期间，有175例自我创伤和441例药物过量就诊病例。自我创伤患者是一个异质性群体，包括表现出自杀相关行为和与自杀无关行为的患者。自我造成的创伤性损伤往往要么相对较轻，要么可能非常严重。上肢撕裂伤最为常见。创伤组和药物过量组几乎是相互独立的人群，且存在一些显著差异。创伤组规模较小，年轻患者和男性的比例显著更高，更常在深夜和凌晨就诊，最终接受的心理咨询较少。这类研究存在报告不足和数据偏差的问题。对自我创伤的前瞻性研究将改善对自我伤害后患者的识别，并增进对损伤模式、精神科诊断与未来自我伤害长期风险之间关系的理解。
