The Industrial Injuries Advisory Council's (IIAC) review of the list of prescribed diseases for which Industrial Injuries Disablement Benefit is payable first began in 1997. Reports of comprehensive reviews of a number of particular diseases have been published since then (Command papers Cm 4280, 5395, 5672, 5997, 6098, 6553, 6645, 6867, 6868). Each prescribed disease has now been reviewed and this report contains a summary of the key findings of the comprehensive reviews. Certain prescribed diseases did not warrant full review, and the Committee also considered several other occupational diseases for prescription, and the findings in relation to both these categories are presented here. Numerous amendments have been made to the list, to ensure the statutory requirements continue to be satisfied and the schedule remains up-to-date in light of current scientific knowledge.
