Rare but Relevant: Characterizing Self-Inflicted Burn Injuries in the United States

Self-inflicted burns (SIBs) represent a distinct entity in burn care often associated with an underlying psychiatric etiology. In this review, we summarize the existing evidence on SIBs in North America to inform targeted prevention and interventions for patients afflicted with SIBs. The following databases were queried to identify relevant articles used for literature review: PubMed, Embase, and Scopus. The main outcome measures were burn characteristics and risk factors of SIBs in the American population. A total of 14,189 patients were included across 13 included studies. The percent of total body surface area burned ranged from less than 1% to 100%, with a mean of 29.6% ± 20.7%. Depressive disorders were the most reported overall; however, among mood disorders, bipolar disorder was also reported frequently, while anxiety was reported least. Motives for self-inflicting burn injury included premeditated self-injury as a coping mechanism, escape or response to delusions, impulsive self-injury, and most commonly, suicidal intention. The majority of the studies reported that preadmission drug and alcohol abuse were associated with the occurrence of SIBs. Other identified risk factors for SIB injury included female sex, younger age, unemployment, and unmarried status. From this, it is imperative that targeted interventions are developed to address the complex interplay of psychiatric disorders, drug use, and other demographic risk factors among the American population. It is crucial for initiatives to emphasize early identification of individuals at risk of self-harm, better access to mental health services, and stronger drug abuse programs to target SIB occurrence in the United States.
