title: [Establishment and validation of an indicator system of risk assessment for mechanical cuts].
abstract: OBJECTIVE
  To establish an indicator system of risk assessment for mechanical cuts, and to validate the system using examples.
  
  
  METHODS
  An indicator system was proposed by the expert investigation method. The index weight, expert authority coefficient, and degree of coordination were determined. The reasonability and stability of the expert questionnaire were evaluated by the reliability analysis. Some on-site examples were given to validate the indicator system.
  
  
  RESULTS
  An indicator system containing 3 first-class indicators, 10 second-class indicators, and 34 third-class indicators was obtained by screening indicators using the boundary value method and the assignment transformation method. The average expert authority coefficient was 0.79. The average expert coordination coefficient was 0.47. The overall reliability coefficient was 0.884. The scores obtained using the indicator system were significantly correlated with the actual injury results in six workplaces (r=0.866, P<0.01).
  
  
  CONCLUSIONS
  The indicator system of risk assessment for mechanical cuts proposed in this study is reasonable and highly consistent with the actual injury results. However, this indicator system still needs further validation and optimization.
