OBJECTIVES: Evaluating local trends and continued monitoring of patterns of acute poisoning are essential for prompt recognition of the toxidromes, the establishment of immediate treatment facilities (e.g., antidote availability), and effective preventive strategies (e.g., governmental regulation on hazardous substances marketing). We aimed to describe the prevalence of the various types of poisoning and associated case fatality in our academic hospital in North India. METHODS: A prospective observational descriptive study was conducted, enrolling patients aged ≥13 years with acute poisoning for 17 months from December 2016 to December 2017 and from September 2019 to December 2019, for a total of 17 months. RESULTS: Four hundred and two patients were enrolled (median age 28 years; 63.2% males). Majority of the acute poisoning cases resulted from ingestion (n = 391, 97.3%) and the primary intention was most commonly self-harm (n = 314, 78.1%). The major types of poisoning were pesticide (n = 264, 65.7%), drug overdose (n = 77, 19.2%), and corrosive ingestion (n = 31, 7.7%). Pesticides included insecticides (n = 146, 36.3%; cholinesterase inhibitors, n = 91), fungicides (n = 76, 18.9%; all aluminum phosphide), herbicides (n = 22, 5.5%; paraquat, n = 19), and rodenticides (n = 20, 5.0%; coumarin-derived substances, n = 12). Benzodiazepines (n = 33) and opioids (n = 25) were frequent causes of drug overdose. 95.3% (n = 379) received preliminary treatment at the previous health-care center, including gastric lavage (n = 239) and antidotes (n = 73). In-hospital case fatality rate was 17.3% (n = 58). CONCLUSION: Herbicide ingestion and opioid overdose are emerging threats with a gradual decline in organophosphate and aluminum phosphide poisoning. Despite improving management of acute poisoning, the overall case fatality rate remains substantial.
