Unlocking Better Asthma Control: A Narrative Review of Adherence to Asthma Therapy and Innovative Monitoring...

This review addresses the ongoing challenges in asthma management, particularly focusing on patient adherence to inhaler therapy. Asthma, a chronic condition characterized by variable respiratory symptoms and airflow obstruction, can lead to significant morbidity and mortality if not properly managed. Despite advances in inhaler technology and therapeutic options, non-adherence remains a significant barrier to optimal asthma control. This review explores both intentional and unintentional non-adherence, influenced by factors such as age, socioeconomic status, and the complexity of inhaler devices. The Global Initiative for Asthma (GINA) provides guidelines aimed at improving adherence through targeted interventions, and this review examines their application. Common inhaler technique errors, including incorrect inhalation speed, not exhaling before inhaling, and failure to hold breath post-inhalation, are identified as major contributors to inadequate asthma control. Furthermore, the review explores the emerging role of electronic monitoring devices (EMDs), such as CapMedic and DigiHaler, which offer real-time feedback to enhance inhaler technique and adherence. The role of biomarkers in assessing adherence and the potential of personalized treatment strategies, including biologic therapies, are also discussed. Overall, addressing adherence requires a comprehensive approach that integrates patient education, tailored interventions, and technological innovations to achieve better clinical outcomes in asthma management.
