Step 1 : Estimate the average age of death due to silicosis or silica-related disease
The approach used to estimate the average age of death due to silicosis or silica-related disease is presented below , with key assumptions underpinning the estimated outlined in Table 33 .
Estimated average age of death due to silicosis or silica-related disease = Average age of diagnosis with silicosis or silica-related disease + Average time between diagnosis of silicosis or silica-related disease and death
Table 33 Estimated average age of death due to silicosis or silica-related disease
Assumption
Value
Average age of diagnosis with silicosis or silica-related disease 43.30 years ( Deloitte 2021 )
Average time between diagnosis of silicosis or silica-related disease and death
Estimated average age of death due to silicosis or silicate related disease
9.30 years ( Deloitte 2021 )
52.6 years
Step 2 : Weighted average life expectancy of people with silicosis or silica-related disease
The approach used to estimate the weighted average life expectancy of people with silicosis or silicarelated disease is presented below , with key assumptions underpinning the estimated outlined in Table 34 .
Weighted average life expectancy of people with silicosis or silica-related disease =
( Proportion of silica-related diagnoses that led to a fatality x estimated average life expectancy of an Australian with silicosis or silica-related disease ) + ( Proportion of silicosis or silica-related diagnoses that did not lead to a fatality x Average life expectancy of an Australian )
Table 34 Weighted average life expectancy of people with silicosis or silica-related disease
Assumption
Value
Proportion of silicosis or silica-related diagnoses that led to a fatality 28 % ( Deloitte 2021 )
Estimated average age of death due to silicosis or silica-related disease
Proportion of silicosis or silica-related diagnoses that do not lead to a fatality
Average life expectancy of an Australian
Weighted average life expectancy of people with a silicosis or silicarelated disease
52.6 years
72 % ( Deloitte 2021 )
82.30 years ( Australian Institute of Health and Welfare 2022 )
74.0 years
