BACKGROUND: Self-immolation is one of the most violent methods of suicide in the developing countries. present study is to investigate survival rate and factors affecting survival of self-immolation patients.
METHODS: All people either died or hospitalized of Intentional burns were assessed in Kermanshah province during 2010 to 2013. Required information gathered from two sources of Kermanshah province legal medicine and burning center of Imam Khomeini hospital. we estimate the survival function through Cox regression. The data analyzed with Stata 12 software.
RESULTS: During 2010 to 2013 (three years), 446 person attempted self-immolation of which 370 were female (83%). In general, 276 people (61.8%) died due to severity of burns. The median of survival time was 47±5 day. The survival rate after one day, one week, and 21 day after accident was 86%, 52%, and 38%, respectively. Multivariate analysis demonstrates that burns is the most powerful risk factor, so that the risk in those with over 70% burns is 17 times more than those with burns less than 30%.
CONCLUSION: Burns percentage is the strongest risk factor, those with high burns percentage should be hospitalized quickly and without waste of time.
