Abstract

Self-inflicted head and neck gunshot wounds are a common modality of suicide in the USA. This study reviewed all self-inflicted head and neck gunshot wound patients with complete records (n = 157) treated at a tertiary centre between 2002 and 2012 inclusive. The associations between mortality and patient/clinical variables were evaluated with the χ2 test or Fisher's exact test for statistical difference testing. Outcomes recorded were death (n = 92, 59%), discharge to long-term care/rehabilitation (n = 58, 37%), and discharge home (n = 7, 4%). The majority of patients were male (86.6%) and single/separated/divorced (55.5%). The mortality rate by site, in descending order, was temporal 82%, frontal scalp 69%, submental/intraoral 30%, and neck 25%. Involvement of the central nervous system (n = 127) resulted in a 70% mortality, but a lower mortality was observed among patients with an avulsion injury (P = 0.025). A tracheostomy within 24 h of admission was statistically associated with improved survival (P < 0.001), but confounding factors were found. Multivariate analysis revealed increasing age, temporal entry site, and the severity of central nervous system involvement to be positively associated with an increased mortality.
