Research objective: 


Objective 1: Determine the pattern and trend of short-acting beta-agonist (SABA) use in relation with the use of inhaled corticosteroids (ICS) in British Columbia (BC) between 1997 and 2014.

Objective 2: Determine the predictors of inappropriate use of SABAs.

Objective 3: Determine the outcomes associated with the inappropriate use of SABAs in relation with ICS.


Hypothesis 1: There continues to be inappropriate use of SABAs in BC across the study period.

Hypothesis 2: Factors such as socio-economic status (SES), demographic factors (sex), and access to care (generalist versus specialist care) are associated with inappropriate use of SABAs.

Hypothesis 3: Inappropriate use of SABAs has been associated with preventable hospital admissions or exacerbations requiring systemic corticosteroids.
