Abstract
AIMS: To explore the utility of self-report measures of inhaled corticosteroid (ICS) adherence, degree of rhinitis and smoking status and
their association with asthma control.
METHODS: Patients prescribed ICS for asthma at 85 UK practices were sent validated questionnaire measures of control (Asthma Control
Questionnaire; ACQ) and adherence (Medication Adherence Report Scale), a two-item measure of smoking status, and a single-item
measure of rhinitis.
RESULTS: Complete anonymised questionnaires were available for 3916 participants. Poor asthma control (ACQ >1.5) was associated with
reported rhinitis (OR = 4.62; 95% CI: 3.71-5.77), smoking (OR = 4.33; 95% CI: 3.58-5.23) and low adherence to ICS (OR = 1.35; 95%
CI: 1.18-1.55). The degree of rhinitis was important, with those reporting severe rhinitis exhibiting the worst asthma control, followed by
those reporting mild rhinitis and then those reporting no rhinitis symptoms (F(2, 3913)=128.7, p<.001). There was a relationship between
the number of cigarettes smoked each day and asthma control (F(5,655)=6.08, p<.001).
CONCLUSIONS: Poor asthma control is associated with self-reported rhinitis, smoking and low medication adherence. These potentially
modifiable predictors of poor asthma control can be identified through a brief self-report questionnaire, used routinely as part of an
asthma review.
