This project uses administrative health databases of the province of British Columbia, Canada, to estimate the economic burden of asthma and chronic obstructive pulmonary disease (COPD), and the role of other medical conditions (comorbidities) that patients with asthma and COPD often have. In particular, the project aims at achieving the following objectives:
 

Primary objectives:

1. Estimate the excess cost of asthma and COPD in BC (excess costs refer to the medical costs patients with asthma and COPD incur which is over and beyond the medical costs of individuals in the general population).

Hypothesis: none; this is a descriptive objective.

2. Estimate the excess costs of co-morbidities in patients with asthma and COPD

Hypothesis: compared to the general population, individuals with asthma/COPD incur more direct medical costs due to co-morbidities than individuals without asthma/COPD

Secondary objectives:

3. Estimate the trend in costs of asthma and COPD over time

Hypothesis: the overall costs of asthma and COPD have increased in the province; the per-patient cost of COPD has increased but the per-patient cost of asthma has decreased.

4. Estimate the contribution of inpatient, outpatient, and medication costs to the economic burden of asthma and COPD and their comorbidities.
