Investigación epidemiológica, descriptiva, en que se evaluaron 284.877 casos en el Sistema Nacional de Notificação de Agravos, durante el periodo de 2007 a 2014. En el análisis de datos se empleó el software Stata 13.

Resultados:

La mayor incidencia de casos ocurrió con las mujeres, 0,8 caso por cada 1.000 trabajadores/año (n = 222.042; 77,9%); del grupo etario de 20 a 24 años con 0,6 caso por cada 1.000 trabajadores/año (n = 64.221; 23,3%); de educación media y superior incompletas con 0,6 caso por cada 1.000 trabajadores/año (n = 141.275; 49,6%). Dichos accidentes ocurrieron con 23 subgrupos ocupacionales. En la mayoría de los accidentes, los trabajadores tenían vínculo laboral, siendo emitida la Comunicación de Accidente Laboral.

Conclusión:

Es necesario repensar las medidas de orientación a los trabajadores sobre los riesgos y las profilaxis de estos accidentes para minimizarlos o disminuirlos.
