Results The crude incidence rate of injury was 3.10%, and 95% confidence interval was 2.79%-3.21%; the standardized incidence rate was 2.50%. The person-time incidence rate of injury was 3.30%; the standardized person-time incidence rate was 2.64%. Top three causes of injury were fall, traffic accident, and burn. Most of injuries occurred at home, streets, and public areas. The major types of injury were superficial injury, dislocation/sprain/strain, and fracture. The average treatment cost for each case was RMB 3 047 Yuan.
