Complementary And Alternative Medication Use And Adherence To Inhaled Corticosteroid Among Inner-city Asthmatics

Background— Complementary and alternative medicines (CAM) are used widely by patients with chronic diseases such as asthma. However, it is unclear whether use of CAM is associated with decreased adherence to inhaled corticosteroids (ICS), a key component of asthma management. Methods— We surveyed 326 adults with persistent asthma receiving care at two inner-city outpatient clinics. Patients were asked about CAM use for treatment of asthma in the prior six months. Medication adherence was assessed using the Medication Adherence Report Scale, a validated self-report measure. Univariate and multiple regression analyses were used to assess the relationship between CAM use, adherence to ICS, and medication and disease beliefs. Results— Overall, 25% (95% CI: 20–30%) of patients reported CAM use. Of those who used CAM, 39% (95% CI: 19–59%) discussed it with their physician, and 21% (95% CI: 12–31%) used CAM in place of prescribed asthma therapy. Univariate analyses showed that CAM use was associated with decreased ICS adherence and increased asthma morbidity. In multivariable analysis, use may a
