Abstract

Abstract : Objective: To determine the prevalence of pesticide, corrosive, drugs, venom and miscellaneous poisoning in India. Setting: Systematic literature search was done in PubMed Central, Cochrane and Google Scholar databases for studies that satisfied the inclusion criteria. Systematic review and meta-analyses of all observational studies published in the English language from January 2010 to May 2020 were included in this review. Participants: Patients exposed to poisoning reported to hospitals were included. Primary and secondary outcome measures: The prevalence of pesticide poisoning was analysed. The prevalence of poisoning due to corrosives, venom, drugs and miscellaneous agents, along with subgroup analysis based on age and region, was also determined. The percentage of persons with poisoning along with 95% CI was analysed. Results: Pooled analysis of studies revealed that pesticides were the main cause of poisoning in adults, with an incidence of 63% (95% CI 63% to 64%), while miscellaneous agents were the main cause of poisoning in children, with an incidence of 45.0% (95% CI 43.1% to 46.9%), among those presenting to hospitals. Pesticide poisoning was the most prevalent in North India (79.1%, 95% CI 78.4% to 79.9%), followed by South (65.9%, 95% CI 65.3% to 66.6%), Central (59.2%, 95% CI 57.9% to 60.4%), West (53.1%, 95% CI 51.9% to 54.2%), North East (46.9%, 95% CI 41.5% to 52.4%) and East (38.5%, 95% CI 37.3% to 39.7%). The second most common cause of poisoning was miscellaneous agents (18%, 95% CI 18% to 19%), followed by drugs (10%, 95% CI 10% to 10%), venoms (6%, 95% CI 6% to 6%) and corrosives (2%, 95% CI 1% to 2%). Conclusions: Pesticide poisoning is the most common type of poisoning in adults, while miscellaneous agents remain the main cause of poisoning in children.
