Fritschi L, Carey R, Peters S, et al., 2014, 0357 The lifetime risk approach to estimating the burden of occupational cancer.
OBJECTIVES: The main approaches to estimating the burden of occupational cancer are attributable risk and lifetime risk. In this presentation we will explain why we used the lifetime risk approach. METHOD: The lifetime risk of cancer is an estimation of an individual's risk of being diagnosed with cancer during their life (without considering occupational exposures). The lifetime risk for the general population (LRGP) is estimated by multiplying cohort person-years-at-risk (from life table data) by age-sex specific incidence rates. The excess lifetime risk of cancer in a cohort of workers exposed to the carcinogen of interest (LRexposed) is a product of the LRGP and the excess relative risk of developing cancer associated with that exposure. LRexposed is multiplied by the prevalence of exposure to obtain the number of cancers attributable to the exposure in the general working population. RESULTS: The lifetime risk approach estimates the number of cancers which would occur over a number of years in the future, due to exposures in a specific year. In contrast, the attributable risk approach estimates the number of cancers which would occur in a specific year due to exposures over a number of years in the past. Because we had exposure prevalence information for a specific year based on a national survey, we determined that the lifetime risk approach was more applicable in our case. CONCLUSIONS: The lifetime risk approach is an alternative method for calculating burden of disease when exposure prevalence information is available.
Demers P, Peters C, Davies H, et al., 2014, 0402 Incorporating more detailed exposure assessment with quantitative estimates is assessing the burden of occupational cancer.
OBJECTIVES: In recent years, several new burden projects have been initiated with increased methodological sophistication. Previous studies have varied with respect to methods used to identify the prevalence and relevant levels of exposure, but many have relied on CAREX estimates. In this presentation, we will focus on the impact of incorporating more detailed exposure assessments with quantitative estimates as part of the Canadian burden of cancer project. METHOD: The Canadian exposure estimation process relies on data from CAREX Canada, taking into account industry and occupation at a more detailed level than previously. For many common carcinogens, the Canadian Workplace Exposure Database is used to account for changes in exposure levels over time and quantitative exposure-response relationships from the literature are used to assign relative risks relevant to the mean level of each exposure group. Historical employment trends are based upon census data at multiple time-points with province, sex, industry, and occupation detail. RESULTS: Developing estimates for approximately 300 industries, as well as by occupation, and the need for estimating the age and gender characteristics of predicted cases to estimate economic burden, has also increased the complexity of estimating historic labour force dynamics. Annual labour force data 1976-2010 is used to attribute age- and tenure-distribution characteristics by province, sex, and industry. CONCLUSIONS: Although our main objective was to increase the validity of the burden estimation process, the more detailed exposure estimates allow us to calculated cancer burden for much more specific industry sectors and occupations, allowing for detailed risk reduction strategies.
Hutchings S, Ayres J, Cullinan P, et al., 2014, 0148 Using the UK Biobank study to estimate occupational causes of chronic disease: comparability with the UK national population and adjustment for bias.
OBJECTIVES: The UK Biobank study is a sample of 502,682 people aged 40-70, clustered around 22 assessment centres. As part of a project to investigate the causes of COPD and estimate the UK occupational burden, we have assessed the sample's representativeness with respect to the UK national population, with a view to accounting for potential biases. METHOD: We have compared characteristics of the Biobank population (age, education, employment, smoking etc) to that of the UK population as estimated from national data sources. RESULTS: Deprivation index scores indicate that Biobank respondents in more affluent wards are over-represented (52% of Biobank respondents versus 28% nationally have scores of less than -2). The Biobank respondents are also better-educated (33% to degree level, 17% nationally), with similar qualification levels in men and women, whereas more men than women nationally in this age range had higher level qualifications. Fewer were currently employed than nationally (58% vs. 65%), particularly men over 60, with more retired (45% vs. 33%), and fewer disabled or unemployed. There are more in managerial and professional (54% vs. 46%), and fewer in routine and manual occupations (22%, 33% nationally), and fewer smokers (33% vs. 49%). Fewer in the already under-represented unskilled occupations (47% vs. 70% for other occupations), or with reported respiratory ill-health (50% vs. 59%) have a usable email address. CONCLUSIONS: As Biobank respondents are on average less deprived, better educated and under-represented in unskilled occupations than the national population, estimating national occupational COPD burden, and collecting further data without bias will require data adjustments.
Driscoll T, Hutchings S, Rushton L, 2014, 0256 Holes in the burden estimates - some can be filled, some maybe not0256 Holes in the burden estimates - some can be filled, some maybe not.
OBJECTIVES: To consider the data shortcomings and methodological decisions involved in current burden of disease studies and the potential for these to be overcome and/or standardised. METHOD: Most burden of disease estimates require considerable assumptions or methodological decisions about factors concerning exposure, the appropriate relative risk to match with the exposure, and/or the size of the exposed population. These assumptions usually arise from a lack of data and could be largely overcome by the provision of better data. It is reasonable to expect that for some areas these data will improve with time, but for other areas the required data will probably never be available. Other assumptions or methodological approaches vary depending primarily on theoretical considerations that are arguable and unlikely to ever be definitively solved by better data availability. Modelling may sometimes be of use but may not always be appropriate or practical and is still likely to involve some assumptions. RESULTS: For example, some countries have reasonable estimates of asbestos exposure and some have good data on at least one asbestos-related outcome (mesothelioma incidence/mortality). How can this information be validly used for burden estimates where such data are poor? CONCLUSIONS: It is helpful to consider the extent to which burden estimates vary depending on the assumptions and methodologies involved when assessing the validity of estimates and their usefulness. Consideration of the potential for future improvements in data and better understanding of theoretical aspects should be an important input into the planning of future burden of disease work.
