Establishment and validation of an indicator system of risk assessment for mechanical cuts / 中华劳动卫生职业病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To establish an indicator system of risk assessment for mechanical cuts, and to validate the system using examples.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSION</b>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.</p>
