688 Characteristics of unintentional and intentional child injuries from emergency and outpatient room in China, 2006–2014

Background Injury is the first death cause of children aged 0 to 17 in China. Prevention of unintentional and intentional injury was totally different. Methods Data collected from National Injury Surveillance System that based on emergency and outpatient department of 126 sentinel hospitals around the whole country through 2006 to 2014 were analysed. Mechanism, place where injury occurred, severity and outcome of unintentional and intentional injuries among patients aged 0 to 17 were summarised. Results Among the 895,243 patients aged 0–17, 94.22% cases were unintentional injuries; 4.84% cases were intentional injuries (interpersonal violence cases: 4.50%, self-injuries: 0.34%). The top injury mechanisms were falling (51.95%), road traffic injury (14.36%), blunt injury (9.59%), animal injury (9.11%) and sharp injury (6.88%) among unintentional injuries; blunt injury (63.73%), sharp injury (12.01%), animal injury (7.94%), falling (4.35%), poisoning (0.56%) among interpersonal violence cases; poisoning (51.96%), sharp injury (21.29%), falling (10.60%), blunt injury (5.66%), road traffic injury (3.70%) among self-injuries. 40.35% of unintentional injuries occurred in home, followed by road (19.53%), school and public place (17.63%), public housing (15.50%); for interpersonal violence cases, 47.64% occurred in school and public place, followed by public housing (19.60%), home (10.69) and road (8.95%); for self-injuries, 65.08% occurred in home, followed by school and public place (12.79%), public housing (10.04%) and road (3.63%). Among unintentional injuries, 81.62% were mitigated injuries, 17.21% were moderate injuries and 1.16% was severe injuries. The proportion of mitigated, moderate and severe injuries among interpersonal violence cases and self-injuries were 79.53%, 18.88%, 1.59% and 51.55%, 38.36%, 10.08% respectively. 86.42% of unintentional injuries were discharged, 12.96% were hospitalised and 0.09% died; the proportion of being discharged, being hospitalised and dying among interpersonal violence cases and self-injuries were 80.16%, 18.96%, 0.08% and 54.32%, 43.98% , 1.08% respectively. Conclusions It’s necessary to have a good understanding of the characteristics of child injuries for child injury prevention.
