INTRODUCTION: The study objectives were to report on current paediatric poisoning figures from South Africa, and to better understand this patient population to contribute suggestions for streamlining local triage and referral criteria.
METHODS: A retrospective review of children presenting to Red Cross War Memorial Children's Hospital (RCWMCH) with poisoning between January 2009 and December 2019 was performed. Data were extracted from the Poisons Information Centre's Clinical Poisonings Database.
RESULTS: There were 3699 incidents, involving 3662 patients; 3011 (81%) patients were under 5 years (median 29 months, IQR 19 to 49 months). There was a slight decline in numbers over the 11-year period.Most patients were referred (n = 2542, 69%), which included a greater proportion that were symptomatic (p < 0.001). There were 8 deaths (case fatality rate 0.2%).Medications were the most common single toxin group (n = 1270, 38%), followed by handyman and industrial (HI) products (n = 889, 27%), household products (n = 451, 14%), and pesticides (n = 445, 13%). There was a significant relationship between toxin type and referral patterns (p < 0.001) as well as clinical severity (p < 0.001): pesticides and HI products (paraffin, n = 486/568, 86%) had a greater proportion of referrals, and pesticides more moderate to fatal poisonings (n = 132/445, 30%), all due to cholinergic (organophosphates and carbamates) and formamidine pesticides.The medication subgroups anticonvulsants (n = 21/78, 27%), anti-infectives (n = 4/34, 12%), multi-vitamin/mineral (MVM) supplements (n = 17/84, 20%), neuropsychiatric medications (n = 50/350, 14%) and substances of abuse (n = 13/47, 28%) had larger proportions of moderate to severe poisonings (p < 0.001), as did the small group of biological toxins (n = 17/55, 31%; p < 0.001).
CONCLUSION: Certain medication, pesticide, and biological toxin subgroups, should be flagged for early referral. The goal is to improve patient outcomes as well as optimize the use of limited resources.
