title: [Construction and evaluation of the epidemiological injury criteria based on the combination of 'Hurt' and 'Harm'].
abstract: OBJECTIVE
  To construct and evaluate the criteria of injury based on the theoretical model that 'Injury' is the combination of 'Hurt' and 'Harm', in order to provide theoretical basis for scientific and rational research on injury in future epidemiological survey.
  
  
  METHODS
  The criteria of epidemiological injury was consected by analyzing documents and consulting experts, then Delphi method was used to evaluate its rationality.
  
  
  RESULTS
  The epidemiological definition for 'Injury'is the combination of 'Hurt' and 'Harm'. 'Hurt' means the wound in clinical medicine, while 'Harm' means the damage from the views of public health. The active coefficients of two rounds Delphi Method were both 100%. The authority coefficients of two rounds were 0.88 and 0.87, respectively. The coordination coefficients were 0.44 and 0.62 (P<0.05), respectively. After two rounds consulting, all scores of rationality for definition of 'Hurt', definition of 'Harm', 'Injury' being the combination of 'hurt' and 'harm', 'Injury' should be graded, Graded based on the 'Injured' time were above 3, and all values of CV for those index were below 0.25 except Graded based on the 'Injured' time.
  
  
  CONCLUSIONS
  The rationality of Definition of 'Hurt', Definition of 'Harm', 'Injury' being the combination of 'hurt' and 'harm', 'Injury' should be graded and Graded based on the 'Injured' time is good. There is still a certain degree of divergence about Graded based on the 'Injured' time.
