Australian trampoline injury patterns and trends

Objectives: To examine national trampoline injury patterns and trends in the context of improved product safety standards and trampoline design modifications. Method: Review of National Hospital Morbidity data. Results: There were an average 1,737 trampoline injuries reported nationally each year from 2002 to 2011. Both injury frequency and rate grew. Statistically significant rate increases were observed among all age groups, although both are highest among children aged 5-9 years. From 2008/09 there is a possible decreasing trend among the 5-9 age group. Falls predominate and 81% of falls result in fracture. Non-fall injuries increased annually as a proportion of all hospitalised injury although they did not comprise more than 2.4% in any one year. Conclusions: History provides no evidence of an observable effect of voluntary Australian Standards for trampoline safety on population rates for trampoline injury. The major design modification - netted enclosures - could contribute to the risk of injury by leading parents to falsely believe that a netted enclosure eradicates the risk of injury.
