Abstract
Background. Poisoning has been reported as the fifth most common cause of injury-related deaths in children younger than five years worldwide. Little is known about accidental poison exposure among children at regional hospital level. Regional hospitals generally provide more specialised support to primary care facilities over a larger area. During the COVID-19 pandemic, lockdown measures may have increased home-based unintentional poisoning.
Objectives. To determine the frequency, outcome and type of accidental poison exposure in children admitted to a regional hospital and compare cases before and during the COVID-19 pandemic.
Methods. A review of admissions to Queen Nandi Regional Hospital in Empangeni was performed to document cases of accidental poison exposure over two years. Equal periods during 2019 and 2020 (April to December) were then compared. Children <13 years of age were included. Age, sex, date of admission, death or survival and type of poisoning were collected.
Results. Cases of accidental poison exposure made up a small proportion of the total admissions over two years (n=252/5 071, 4.97%) with a low case fatality rate (0.40%). Boys made up the majority (n=132/252, 52.38%). Most were <five years old (n=220/252, 87.30%). Medicines (n=114/252, 45.24%), hydrocarbons (n=59/252, 23.41%) and pesticides (n=26/252, 10.32%) were the main types of poison. Domestic cleaner-, sanitiser- and disinfectant-related admissions were significantly increased during the pandemic (p=0.020).
Conclusion. Accidental poison exposure occurs commonly in younger children. Medicines, hydrocarbons and pesticides made up the majority of cases. Domestic cleaner, hand sanitiser and disinfectant ingestion increased in the pandemic. Future research should involve primary care facilities, and risk factors as well as clinical severity should be investigated.
