BACKGROUND: People who deliberately ingest poisons commonly present to emergency departments of hospitals in India. However, there is a dearth of information on poisoning using nonorganophosphorus pesticides.
METHODS: This prospective, hospital-based study attempted to examine the nonorganophosphorus poisons used to attempt suicide. Data on sociodemographic characteristics of patients, site and source of poisons, co-ingested substances, premeditation, and reason for poisoning were collected. A multinomial logistic regression was performed to determine association between poison class and these exposure characteristics.
RESULTS: Three hundred and forty-one cases of attempted suicide presented during the 6-month period (1.7% of all emergency room admissions). The majority was predominantly male and was young adults. Poisoning was the most common mode (91.7%), followed by hanging (7.3%) and self-injury (3, 0.9%). Pesticides (44.3%) including organophosphates (25.5%) were the predominant poisons, followed by pharmaceuticals (27.9%), caustics/chemicals (12.0%), and plant poisons (7.0%). One hundred and nine were available for prospective interview as the others who presented were not detained for prolonged observation the emergency department. Most patients who ingested such poisons were women, from rural backgrounds and were educated. The majority sourced the poisons from home, consumed poison at home, and mixed the poison with water; these attempts were impulsive and seemed to be in response to relationship conflicts. In the multivariate analysis, education (P = 0.08) and poison source (outside the home) were significant predictors of pesticide ingestion.
CONCLUSIONS: Suicidal poisoning results from a complex synthesis of socioeconomic and psychological factors; certain patterns of poisoning are likely to be more prevalent in demographic niche groups.
