Quality information

Estimates of disease burden due to selected risk factors in the Australian Burden of Disease Study 2018 were produced using the best possible data available in the scope and time frame of the study.

To provide information on the quality of estimates, a quality index was developed to rate estimates based on the relevance and quality of source data, and methods used to transform data into a form required for this analysis. In general, the higher the rating, the more relevant and accurate the estimate.

For each risk factor, it was only possible to rate the quality of the data used to estimate the direct population attributable fraction (PAF) or the exposure data used to calculate the PAF. Other inputs (such as relative risks) were included in these calculations, however it was not feasible in the scope of this project to determine the quality of these inputs. For more information on the inputs used to estimate risk factors refer to the Australian Burden of Disease Study 2018: methods and supplementary material.

Use the interactive tool to explore the quality information for risk factor exposure estimates for each risk factor for the year 2018 at the national level.

This interactive data visualisation reports on the quality information regarding the attributable burden estimates for each risk factor, which can be selected by the user. For each risk factor, there are two scores – one for data and one for methods. Each score is a whole number out of 5. There is a description of the data and methods used to obtain the attributable burden estimate. There is also a table describing the criteria used for all risk factors to assign data and method scores.
