Direct costs of occupational asthma due to sensitization in Quebec (1988 to 2002): revisited.

BACKGROUND: In a previous study, the authors assessed direct costs for occupational asthma (OA) in a random sample of eight to 10 accepted claims per year for OA between 1988 and 2002. Compensation for loss of income (CLI) was found to be significantly higher for men and for OA caused by low-molecular-weight agents.
