A Retrospective Analysis of Pattern of Suicide in Autopsied Cases in a Tertiary Care Hospital

Background:The National Crime Records Bureau of India reported a decline in suicide rate from 2010 through 2014. We conducted this study to know whether our hospital data reflects the national data and to know the age and gender specific differences in selecting methods of suicide. Methods: We conducted a retrospective analysis of autopsied cases in Department of Forensic Medicine in a tertiary care hospital in central Kerala, India. Data on age, gender, cause of death of autopsied cases with alleged history of deliberate self-harm (DSH) were noted. Results: Mean age of study population was 43.4±24.4. There were 59.3% males and 40.7% females, but young females outnumbered young males. Majority of cases were hanging (n=1325), followed by poisoning (n=1169), burns (n=809), drowning (n=626) and others (n=401). Hanging and poisoning were the common methods chosen by males while burns and poisoning were the common methods by females. The number of DSH cases was 1,040, 866, 771, 837 and 826 in each year from 2010 to 2014, respectively. Number of poisoning cases was declining steadily from 350 to 163 while non-poisoning suicide was not showing any steady changes (690, 578, 514, 657, and 663). Pesticides were the most common agent recorded in the autopsy sheet while corrosives, plant toxins, cyanide, toxic alcohol and drug overdose were less common. Quinalfos, chlorpyrifos and carbofuran were the commonly identified pesticides on chemical analysis. Conclusion: There is a decrease trend in the number of suicides over the 5 years from 2010 through 2014 with a decrease in suicide due to poisoning. Though there is minimal increase in suicide due to hanging, it did not affect the total number of suicides.
