Playground Equipment Related Injuries in Preschool-Aged Children: Emergency Department-based Injury In-depth Surveillance

In this study, we investigated playground equipment related injuries in preschool-aged children. This was a retrospective observational study using Emergency Department based Injury In-depth Surveillance, (2011-2014). We included the preschool-aged children with playground equipment related injuries. We surveyed the mechanism and incidence of injuries, and estimated the odds ratio (OR) of traumatic brain injury (TBI) and upper/lower extremities fracture. There were 6,110 patients, mean age was 4.14 ± 1.95 years old. Slide and swing related injuries were 2,475 (40.5%) and 1,102 (18.0%). Fall down (48.5%) was the most common mechanism. The OR of TBI in children 0-2 years old was 1.88 times higher than children 3-7 years old, and in swing was 4.72 (OR, 4.72; 95% confidence interval [CI], 2.37-9.40) times higher than seesaw. The OR of upper extremity fracture in children 3-7 years old was 3.07 times higher than children 0-2 years old, and in climbing was 2.03 (OR, 2.03; 95% CI, 1.63-2.52) times higher than swing. The OR of lower extremity fractures in horizontal bars, tightropes, and trampolines was 2.95 (OR, 2.95; 95% CI, 1.55-5.61) times higher than swing. The most common mechanism and playground equipment were fall down and slide. TBI was associated to younger children (0-2 years old) and swing. Fracture of upper extremities was associated to older children (3-7 years old) and climbing. Fracture of lower extremities was associated to others such as horizontal bars, tightropes, and trampolines.
