Findings from a Propeller Health study recently published in The Journal of Allergy and Clinical Immunology demonstrated that patients with asthma who are prescribed once-daily dosing schedules are more likely to adhere to their controller medications than those with twice-daily prescriptions.
Medication adherence data was collected from 6,410 patients who used the Propeller digital health platform. The platform’s inhaler sensors attach to a patient’s inhaler medications and passively capture the date and time of controller medication use.
Following a three-month study period, we found that on average, once-daily users had significantly higher daily adherence than twice-daily users. This pattern persisted even when comparing adherence rates across age groups, with the exception of 4-11 year olds, who may benefit from additional parental oversight.
The percentage of patients who achieved greater than 80% adherence was also significantly higher for once-daily users compared to twice-daily users, with once-daily users being 1.4 times as likely to achieve high medication adherence as twice-daily users.
