Background: Chronic obstructive pulmonary disease (COPD) patients often have poor health literacy, leading to non-adherence to treatment and poor inhalation technique. Technological solutions can help manage COPD, but adherence tends to be low due to various factors. Objectives and Methods: We conducted a qualitative study to determine the needs of COPD patients and healthcare practitioners (HCPs) towards a mobile application and a web platform. We also aimed to identify potential barriers or facilitators to the use of such digital tools and their potential impact, and to assess the current state of collaboration between healthcare practitioners. Results: Our study found that COPD patients face difficulties in managing the disease and treatments, lack information and need easier contact with caregivers. Patients’ needs include access to reliable information about COPD, its medical treatments and smoking cessation, help in maintaining good physical condition through adapted exercises, incentives and reminders, and crisis management protocols or a logbook. As patient needs can differ, it would be ideal if the mobile application could be customized. HCPs cite patient adherence, correct intake of the treatment, communication and lack of patient motivation as challenges. In particular, they would like to have access to information on patient follow-up and logbooks, as well as scientific documentation. They believe that interprofessional collaboration is essential for good patient care. However, lack of time is a major hurdle in optimizing this collaboration. Conclusion: Our study showed that most patients and HCPs view a technological platform positively to support the care of COPD patients and promote interprofessional collaboration.

Background/Objectives: Therapeutic adherence to asthma and COPD medications remains worryingly low and varies widely across patient groups, underscoring persistent challenges in chronic respiratory care. The aim of this nationwide study is to quantify real-world adherence and to identify its demographic and clinical determinants using the Belgian health care claims database of the National Institute for Health and Disability Insurance (NIHDI). Methods: Adherence was assessed using the Continuous Multiple Interval Measure of Medication Availability (CMA) among patients treated between 2020 and 2023. Mixed-effects logistic regression was applied to identify determinants of adherence. Results: Only 30.5% of patients achieved good adherence (CMA ≥ 0.8). Adherence varied substantially across pharmacological classes, ranging from 8.1% for inhaled corticosteroids to 66.4% for triple therapy. Age emerged as a major determinant, with adherence increasing steadily across age groups: only 4.0% of children and 15.7% of adolescents reached good adherence, compared with progressively higher rates in adults. Mixed-effects logistic regression confirmed age, sex, and pharmacological class as robust predictors of adherence. Conclusions: These findings highlight the magnitude of the therapeutic adherence gap in chronic respiratory diseases and clearly identify children, adolescents, and ICS or LABA + ICS users as the highest-risk groups. Recognizing these profiles has direct implications for clinical practice, as it provides concrete targets for future patient-centered interventions and guideline-concordant adherence-enhancing strategies.
