The economic burden of asthma in Canada
1) To estimate the direct and indirect costs of asthma in British Columbia (BC), and the
impact of asthma on quality of life;
2) To estimate the burden of asthma by levels of severity and control;
3) To extrapolate the data and develop a province-wide and Canada-wide burden of
1) To examine the determinants of healthcare resource utilization and quality of life in
patients with asthma;
2) To examine the impact of asthma on work productivity (absenteeism and presenteeism);
3) Comparing the retrospective versus prospective calculation of direct asthma costs;
4) Developing an algorithm for assigning levels of severity and control based on
5) To predict the direct and indirect cost of asthma for the next 10 years.
- Asthma is associated with a significant burden, in terms of direct and indirect costs, and quality-of-life in Canadians;
- The burden of asthma is adversely correlated with level of control;
- Without significant changes in the management of asthma, the burden of asthma in future will increase.
