Inequalities in hospital admission rates for unintentional poisoning in young children.

OBJECTIVE

To determine the relationship between deprivation and hospital admission rates for unintentional poisoning, by poisoning agent in children aged 0-4 years.

DESIGN

Cross sectional study of routinely collected hospital admissions data.

SETTING

East Midlands, UK.

PARTICIPANTS

1469 admissions due to unintentional poisoning over two years.

MAIN OUTCOME MEASURE

Hospital admission rates for unintentional poisoning. Incidence rate ratios (IRRs) comparing hospital admission rates for poisoning in the most and least deprived electoral wards.

RESULTS

Children in the most deprived wards had admission rates for medicinal poisoning that were 2-3 times higher than those in the least deprived wards (IRR 2.49, 95% CI 1.87 to 3.30). Admission rates for non-medicinal poisoning were about twice as high in the most compared to the least deprived wards (IRR 1.77, 95% CI 1.19 to 2.64). Deprivation gradients were particularly steep for benzodiazepines (IRR 5.63, 95% CI 1.72 to 18.40), antidepressants (IRR 4.58, 95% CI 1.80 to 11.66), cough and cold remedies (IRR 3.93, 95% CI 1.67 to 9.24), and organic solvents (IRR 3.69, 95% CI 1.83 to 7.44).

CONCLUSIONS

There are steep deprivation gradients for admissions to hospital for childhood poisoning, with particularly steep gradients for some psychotropic medicines. Interventions to reduce these inequalities should be directed towards areas of greater deprivation.
