Brief Summary
Inhaler nonadherence is a common problem that has been estimated to account for approximately 60% of all asthma-related hospitalizations. Unfortunately, prior interventions to improve inhaler nonadherence have shown a lack of long-term success. This study proposes to assess the problem of non-adherence using a D\&I research lens while testing a new inhaler approach to potentially ameliorate the detrimental consequences of maintenance inhaler nonadherence.

Outcome Measures
Primary Outcomes (1)
Adherence to inhaler strategy delineated using an electronic inhaler sensor
The primary outcome will be adherence with an inhaler management strategy delineated using the Adherium inhaler sensor and smartphone application as compared between groups. Adherence to the treatment strategy for the maintenance ICS inhaler group will be calculated as the proportion of maintenance ICS actuations per prescription recommendation. Adherence for the symptom-based ICS treatment strategy will be calculated as the proportion of ICS/LABA actuations per recommendation based on self-report of symptoms (definition: ICS/LABA inhaler actuation during a day or night period divided by a period wherein a patient identified symptoms as \>1 on REDCap-delivered smartphone questionnaire).

Study Arms (2)
As needed inhaled corticosteroid and long-acting beta-agonist
ACTIVE COMPARATORSymptom-driven ICS/LABA treatment strategy
Standard therapy: maintenance inhaled corticosteroid and as needed short-acting beta-agonist
PLACEBO COMPARATORContinue maintenance ICS and SABA therapy
Interventions
In this intervention, patients will be assigned to a standard therapy with a maintenance inhaled corticosteroid (Flovent) and an as needed short-acting beta-agonist and their adherence to this regimen will be assessed and compared to patients taking a regimen with an as needed inhaled corticosteroid and long-acting beta-agonist.
In this intervention, patients will be assigned to a symptom-driven budesonide/formoterol combination therapy (Symbicort) and their adherence to this regimen will be assessed and compared to patients taking a standard therapy with a maintenance inhaled corticosteroid and as needed short-acting beta-agonist.
Eligibility Criteria
You may qualify if:
- Able to understand and provide informed consent.
- Age 18-75 at the time of study enrollment.
- Provider diagnosed mild or moderate persistent asthma and prescribed maintenance ICS treatment and as needed SABA for at least 6 months prior to enrollment.
- Suboptimal adherence to prescribed maintenance ICS therapy defined as missing at least expected 2 ICS refills in the prior 6 months based on examination of pharmacy records or a Medication Adherence Report Scale for Asthma (MARS-A) score \<4.5.
- An Asthma Control Test (ACT) score at enrollment greater than or equal to 12 but less than or equal to 20 indicating partially controlled or moderately uncontrolled asthma.
- iPhone or Android smartphone with an active data plan and willingness to use the Adherium device.
You may not qualify if:
- Relevant comorbid pulmonary diseases including, but not limited to a diagnosis of chronic obstructive pulmonary disease (COPD), cystic fibrosis, or alpha 1 anti-trypsin deficiency.
- Current use of a biologic medication or investigational treatment for asthma.
- History of asthma requiring ICU admission in the last year.
- Unwillingness to use or pay for an inhaler that is compatible with the Adherium sensor (fluticasone propionate or budesonide/formoterol). Of note, fluticasone and budesonide/formoterol are formulary tier 1-2 for Missouri Medicaid and most commercial insurances and are believed to be equally or less expensive as alternative inhalers for most patients.
- Any clinically significant abnormalities on physical exam, laboratory testing, or baseline diagnostic testing that the study team believes will make the study unsafe.
- Patients who do not complete at least 70% of the twice-daily texts during the two weeks after screening.
