TRAINING INHALATION TECHNIQUE: DYNAMICS OF SYMPTOMS AND LUNG FUNCTION PARAMETERS IN PATIENTS WITH COPD AND ASTHMA IN REAL-WORLD CLINICAL PRACTICE
Abstract
Objective: To assess the impact of structured training in inhalation technique and optimization of inhaled treatment regimens on symptoms, quality of life and pulmonary function in patients with COPD and bronchial asthma in real‑world clinical practice. Methods: This open-label study enrolled 38 adult patients with COPD or asthma who had signs of inadequate disease control and at least one critical inhaler technique error. Over 8 weeks, patients underwent “teach‑togoal” training with individualized demonstration, step-by-step practice using pMDIs and DPIs, and provision of written leaflets, while inhalation therapy was simultaneously optimized according to GOLD and GINA recommendations. mMRC, CAT, ACT/ACQ, visual analogue scales and spirometry were assessed.
Results: Training resulted in a marked reduction in the frequency of critical errors, improvement in symptoms and CAT/ACT/ACQ scores, as well as a moderate increase in FEV1, confirming the clinical relevance of regular assessment and correction of inhalation technique.
