Symptom-driven ICS/LABA Therapy for Patients With Asthma Non-adherent to Daily Maintenance Inhalers

While inhaled corticosteroids (ICS) are considered the essential foundation of most asthma therapy, ICS inhaler non-adherence is a notoriously common problem and a significant cause of asthma-related morbidity. Partially acknowledging the problem of non-adherence, international organizations recently made paradigm-shifting recommendations that all patients with mild or mild-to-moderate persistent asthma be considered for symptom-driven ICS-containing inhalers rather than relying on adherence to traditional maintenance ICS inhalers and symptom-driven beta-agonists. With this novel approach, asthma patients are at least exposed to the important anti-inflammatory effects of ICS-containing inhalers when their inhaler is deployed due to symptoms. The proposed study aims to (Aim 1) undertake a pragmatic pilot randomized-controlled trial to evaluate if an inhaler strategy that utilizes symptom-driven ICS inhalers is particularly accepted and beneficial in maintenance ICS inhaler non-adherent asthma patients, and (Aim 2) use a D\&I science conceptual framework to better understand patients' and providers' views of inhaler non-adherence. This study will use an electronic sensor to monitor inhaler adherence and include semi-structured interviews using the Consolidated Framework for Implementation Research (CFIR).
