BACKGROUND: @entity2 can be caused by occupational exposure. This is not always recognised or reported, and not all @entity1 receive the benefits to which they are entitled. MATERIAL AND METHOD: We collected occupational case histories for @entity1 from S  r-Tr  ndelag county with a first-time diagnosis of @entity2 . The number of reported cases of occupationally related @entity2 was collected from the Norwegian Labour Inspection Authority, and information on approval of occupational illness was collected from the Norwegian Labour and Welfare Authority (NAV). RESULTS: 105 @entity1 with @entity2 took part in the study, 73 @entity1 and 32 @entity1 . Among the @entity1 , altogether 12 cases (16%) were assessed as likely and 16 (22%) as possibly occupationally related. Among the @entity1 , none of the cases were assessed as occupationally related. The reporting frequency from the health regions to the Norwegian Labour Inspection Authority varied from 1.7% to 5.1%. Altogether 9 out of 11 likely cases and 5 out of 12 possible cases of occupationally related @entity2 were granted injury compensation by the Norwegian Labour and Welfare Authority. INTERPRETATION: In this study, we found that approximately 20% of the cases of @entity2 in @entity1 are occupationally related, and that the underreporting of occupationally related @entity2 appears to be considerable. The obligation of doctors to report to the Norwegian Labour Inspection Authority should be made better known. Most likely, more @entity1 would have had their @entity2 verified as an occupational illness and could have received injury compensation if they had been aware of the opportunity to apply for this.
