Abstract
Background: The design of inhaler devices may potentially influence adherence/persistence and outcomes in asthma. Objective: The primary objective was to assess asthma control and any change in the quality of life in patients using an intuitive dry powder inhaler containing fluticasone propionate/salmeterol (AirFluSal® Forspiro®) for the treatment of asthma in everyday practice. Methods: ASSURE was a multicenter, noninterventional, open-label, prospective study in patients with asthma, aged ≥12 years and treated with the Forspiro device in Denmark, Sweden and Norway. Patients' opinions of their asthma control were assessed by the Asthma Control Test (ACT) questionnaire and asthma-related quality of life by the Mini Asthma Quality of Life Questionnaire (miniAQLQ) at baseline and at two follow-up visits (approximately 4-8-week intervals). Results: Of 321 patients enrolled in the study, 299 received at least one dose of fluticasone propionate/salmeterol via the Forspiro device and 204 had evaluable data at the baseline visit and at least one later visit. Patients showed improvements in asthma control and quality of life during the study. The mean sum score of ACT increased from 18.0 (SD 4.5) at visit 1 to 19.9 (4.2) at visit 2 and 20.5 (4.3) at visit 3. Overall, 38.2% of patients improved by the minimal clinically important difference (MCID) of ≥3 points (45.6% among those with a baseline score below 23 [ie, not already well controlled]). The mean score on the miniAQLQ increased from 5.16 (SD 1.24) at visit 1 to 5.58 (SD 1.20) at visit 2 and 5.82 (SD 1.04) at visit 3. Overall, 42.6% of patients improved by the MCID of ≥0.5. Conclusion: This real-life study suggests that treatment with fluticasone propionate/salmeterol via the Forspiro device can improve asthma symptom control and quality of life.
期刊介绍：
Pragmatic and Observational Research is an international, peer-reviewed, open-access journal that publishes data from studies designed to closely reflect medical interventions in real-world clinical practice, providing insights beyond classical randomized controlled trials (RCTs). While RCTs maximize internal validity for cause-and-effect relationships, they often represent only specific patient groups. This journal aims to complement such studies by providing data that better mirrors real-world patients and the usage of medicines, thus informing guidelines and enhancing the applicability of research findings across diverse patient populations encountered in everyday clinical practice.
