BACKGROUND: Chronic obstructive pulmonary disease (COPD) is common around the world and carries a high morbidity and mortality. Symptom- and risk-oriented drug treatment is recommended, both in Germany and in other countries. It is not yet known to what extent the treatment that is actually delivered in Germany corresponds to the current recommendations in the guidelines. METHODS: As recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) in 2017, 2281 patients of the national COPD cohort COSYCONET (COPD and Systemic Consequences-Comorbidities Network) were classified into Gold classes A-D on the basis of disease-specific manifestations and the frequency of exacerbations. Moreover, the regular use of medications was documented and categorized according to active substance groups. For all groups, the documented treatment that was actually given was compared to the recommended treatment. RESULTS: 67.6% of the patients received a combination of a long-acting anticholinergic drug (LAMA) and a long-acting beta-mimetic drug (LABA), while 65.8% received inhaled corticosteroids (ICS), 11.7% theophylline, and 12.6% oral corticosteroids (OCS). Despite recommendations to the contrary, 66% of the patients in Groups A and B (low exacerbation rates) were treated with ICS; some of these patients carried an additional diagnosis of bronchial asthma. There was evidence of undertreatment mainly in groups C and D (high exacerbation rate), because many of the patients in these groups were not treated with LAMA or LAMA/LABA as recommended. CONCLUSION: The observed deviations from the recommended treatment, some of which were substantial, might lead to suboptimal treatment outcomes as well as to avoidable side effects of medication.
