Title Preliminary report of mortality among workers compensated for work-related asthma
Bibliographic information May 1999, Vol.35, No.5, p.465-471. 32 ref.
Abstract Subjects receiving compensation for occupational asthma (OA) or aggravation of asthma (AA) and a comparison sample of workers with claims for musculoskeletal injuries during the same period were identified from the Ontario Workers' Compensation Board, along with another comparison group of non-compensated asthmatic patients seen at a hospital clinic during the same period. Mortality of the three groups were compared with that of the general population. Of the 66 deaths identified, only 2 deaths were due to asthma, both in the work-related asthma group: one from the index cluster, and one not previously identified. A second index death was coded as dying from chronic obstructive pulmonary disease not elsewhere classified. There were fewer deaths than expected from most causes. In direct comparison of the work-related asthma claimants with the injury claimants, the risk of death appeared elevated from respiratory disease and ischaemic heart disease but the confidence intervals included unity. Excess deaths from respiratory disease, in particular asthma, may occur among those with work-related asthma even in the absence of re-exposure.
