Abstract: Objective To understand the distribution of injury cases in Zhangjiagang, Jiangsu province, in 2011 and provide evidence for the development of injury prevention and control strategy. Methods According to the WHO injury surveillance criteria, the classification and analysis were conducted on the injury incidence data reported by 3 sentinel hospitals in Zhangjiagang in 2011. Results A total of 28 807 injury cases were reported in 2011. The male to female ratio of the cases was 1.6, and the cases were mainly aged 25-44 years(37.62%). The first three injury causes were traffic accidents(22.53%), falls(22.21%) and blunt strikes(18.67%). The major places where injuries occurred were industry/construction sites(29.65%), road/street(27.79%) and home(25.29%). Most cases were unintentional(94.95%) and mild(71.55%) injuries. Conclusion Sentinel surveillance of injury in hospital would play an active role in determining injury intervention focus and reducing the incidence of injury because it is the important source of injury information.
