Qualitative study of user perspectives and experiences of digital inhaler technology.

Electronic monitoring devices (EMDs) have been trialled in interventions to improve inhaled corticosteroid adherence and clinical outcomes. This study sought to understand the perceptions and experiences of EMD end-users. Participants recruited into a six-month EMD study were invited to a semi-structured interview. Interviews were audio-recorded, transcribed verbatim and analysed using the framework approach. Twenty-eight participants (68% female, median age 47) were interviewed. Individuals described feeling responsible for their asthma control. Recent attacks motivated a desire to maintain control. Study participation led to increased awareness of asthma status and medication use. Several individuals were open to integrating digital monitoring data with other mHealth inputs, perceiving the potential to enhance communication with clinicians and empower self-management. Openness to data sharing was tied to expectations of transparent data use. Data supported integrating beliefs and habit formation to achieve behaviour change. There was a willingness for an integrated, platform-based approach to digital self-management.

Con: Access to advanced therapies for severe asthma should be restricted to patients with satisfactory adherence to maintenance treatment.

Current guidance states that advanced therapies should only be used when adherence to maintenance therapy (inhaled corticosteroid/long-acting ß-agonist) has been proven. This is based on the costs of advanced therapies, the fact that they were generally trialled as add-ons to maintenance therapy, and the assumed efficacy of maintenance therapy in the majority of adherent patients. In this pro/con debate, we argue that such a rigid view of access downplays the complex and multifactorial nature of poor adherence. Not only does the evidence indicate a role for psychosocial factors in both poor adherence and poor asthma outcomes, failure of maintenance therapy itself may be a driver of poor adherence behaviours. Some individuals at high risk of poor asthma outcomes will therefore also have poor adherence that is not rapidly amenable to intervention. Rather than punishing them for factors outside of their control, they should be allowed access to advanced therapies in order to reduce their adverse risk resulting from uncontrolled asthma.
