Analysis of primary disability in determining the connection between disease and occupation

Average age at first disablement status by primary diagnosis of occupational diseases reaches 51.8 +/- 4.1 years. Medical and social examination proves II grade disablement in 15% of individuals. Disablement due to occupational diseases is characterized by high stability (60.5 out of 100 repeatedly examined per year). The authors revealed statistically significant (p < 0.001) dependence of disablement degree on the disease duration until the relationship between the disease and occupation is established.
