Purpose: Dyspnea is a leading symptom of COPD that causes presentations in emergency departments or negatively impacts on them. Guideline-based inhalation therapies are intended to reduce dyspnea in COPD patients. This study analyzed how common guideline recommended inhalation therapy regimens are occurring in clinical practice among COPD patients presenting to emergency departments due to adverse drug reactions in polytherapy using data of the German ADRED database. Patients and Methods: In total, 269 COPD cases were identified. In a further analysis, all cases were analyzed for documented GOLD stage and guideline-recommended inhalation therapy for COPD. Dyspnea and other symptoms identified during ED presentation were analyzed and compared between patients who did and did not receive the guideline's recommended inhalation therapy. Results: In this observation, 41% (n = 46) of all 112 cases with a documented COPD and GOLD stage received an underdosed therapy according to current guidelines. Dyspnea was the most common identified symptom (32%, n = 36) in this cohort and occurred more often in patients who received an underdosage of inhalation therapy (p < 0.01). Conclusion: Patients with COPD presenting to ED with ADRs show a high rate of non-guideline-recommended inhalation therapy and present more often with dyspnea compared to those COPD patients who received an adequate dosing of inhalation therapy.
