Spectrum of unnatural fatalities in the Chandigarh zone of north-west India--a 25 year autopsy study from a tertiary care hospital.
A 25 year (1977-2002) autopsy study of 5933 unnatural fatalities from a tertiary care hospital of north-west India revealed an abrupt rise in unnatural deaths (3050; 51.4%) since 1997. 84.2% subjects were between the age group of 16 and 45. Accidental deaths (79.3%) constituted the majority of unnatural fatalities followed by suicidal (13.9%) and homicidal (6%) deaths. Road traffic accidents (RTAs), burn, poisoning, accidental falls from height and firearm injury were responsible for 94.5% of the total unnatural deaths. A male preponderance (73.4%) was seen in all causes of deaths except for burns where females (61%) outnumbered males (39%). The incidence of fatalities due to poisoning and burns had increased from 5.7% and 22.6% to 12% and 24.3%, respectively, whereas due to fire arms and machinery accidents decreased from 4.5% and 1.2% to 1.2% and 0.4%, respectively. The proportion of mortality due to road traffic accidents (50.3%) and accidental fall from height (6.9%) remained almost static. Two-wheeler occupants (motor cycles, etc. 33.3%) were the main victims in road traffic accidents. Pouring of kerosene oil (36% dowry death), malfunctioning and bursting of kerosene oil stove (43.5%) were the most common factors in burn deaths. Between 1977 and 1987 barbiturates (33.3%), organophosphates (23.8%) and copper sulphate (14.3%) and in 1987-1997 organophosphates (45%) and aluminium phosphide (26.5%) were the major fatal poisons. Since 1992 aluminium phosphide (80%), a fumigant pesticide used for wheat preservation was the most common poison. The incidence of suicidal deaths increased from 10.9% (1987-1992) to 15.7% (1997-2002) with a peak incidence of 18.2% in 1992-1997, when this pesticide with no effective antidote was made freely available in the market.
