Self-inflicted burns are a relatively uncommon but profound attempt at suicide. Twenty years ago, we first reviewed our experience with self-inflicted burns. With this current study, we sought to determine whether there had been any change in the incidence or outcomes of self-inflicted burns. All burn patients admitted between January 1, 2012, and December 31, 2021, with self-inflicted burns were compared with all other admissions. The frequency of self-inflicted burns and confounding risk factors of patients with self-inflicted burns remained unchanged. A large proportion (87.4 %) of the patients had psychiatric disease. They also had larger burns and higher mortality than accidental burns. Unexpectedly, logistic regression analysis that controlled for age, total percent total body surface area (TBSA) burn, sex, and inhalation injury revealed that those patients with self-inflicted burns had 72 % lower odds of dying than the general population. In conclusion, there has been no improvement in the incidence of self-inflicted burns. They result in very severe injuries, but when age, burn size, gender, and inhalation injury are controlled for, they have at least as good a chance for survival as the general burn population.
自伤性烧伤是一种相对罕见但严重的自杀企图。二十年前，我们首次回顾了我们在自伤性烧伤方面的经验。通过这项当前研究，我们试图确定自伤性烧伤的发生率或结局是否有任何变化。将2012年1月1日至2021年12月31日期间收治的所有自伤性烧伤患者与所有其他入院患者进行比较。自伤性烧伤患者的频率和混杂风险因素保持不变。很大一部分（87.4%）患者患有精神疾病。他们的烧伤面积也比意外烧伤更大，死亡率更高。出乎意料的是，在控制了年龄、总体表面积（TBSA）烧伤百分比、性别和吸入性损伤的逻辑回归分析中发现，自伤性烧伤患者的死亡几率比普通人群低72%。总之，自伤性烧伤的发生率没有改善。它们会导致非常严重的伤害，但在控制了年龄、烧伤面积、性别和吸入性损伤后，它们至少与普通烧伤人群有同样的生存机会。
