Abstract
Poor adherence to inhaled corticosteroids (ICSs) and overuse of short-acting beta2-agonists (SABAs) are associated with increased asthma morbidity. To assess whether patient self-monitoring viaelectronic medication monitoring and smartphone application plus remote clinician feedback influences ICS and SABA use. Adults with uncontrolled asthma and prescribed ICS and SABA were enrolled in this 14-week study. Inhalers were fitted with electronic medication monitoring to track real-time usage. After a 14-day baseline, participants were randomly assigned to the treatment group where they received reminders and feedback on ICS and SABA use via a smartphone application and clinician phone calls, or control group without feedback. Linear mixed models compared the baseline percentage of SABA-free days and ICS adherence to the last 14 study days. Participants (n= 100) had a mean age of 48.5 years, 80% were female, 68% white, and 80% privately insured. The percentage of SABA-free days increased significantly in the treatment group (19%; 95% CI, 12 to 26; P < .01) and nonsignificantly in the control group (6%, 95% CI,-3 to 16; P= .18), representing a 13% (95% CI, 1-26; P= .04) difference. ICS adherence changed minimally in the treatment group (-2%; 95% CI,-7 to 3; P= .40), but decreased significantly (-17%; 95% CI,-26 to-8; P < .01) in the control group, representing a 15% (95% CI, 4 to 25; P < .01) difference. Patient self-monitoring via a digital platform plus remote clinician feedback maintained high baseline ICS adherence and decreased SABA use.
