ABSTRACT

Introduction: Morbidity and mortality due to chronic obstructive pulmonary disease (COPD) are on the rise worldwide. The cornerstone of treatment is maintenance inhaled therapy and the patients' good treatment adherence. Objective: To determine epidemiological and treatment characteristics of patients treated with COPD in Hungary. Methods: Using data from the National Health Insurance Fund, we recruited patients under maintenance inhaled therapy due to COPD between 2011 and 2019 (aged >40 years, who filled in at least one prescription of a maintenance inhaled drug for ICD (International Classification of Diseases) code J44, which was followed by two further prescriptions within 1 year). Data of patients were analysed every year after inclusion. Findings on age, sex, inhaled therapies, and the use of retard oral theophylline were compared among the years (chi2 test). Results: In total, 227,251 patients were included (2011­2019 81,308­160,241 patients/year). In 2011, most patients were >70 years of age and males, while in 2019, most patients were 60­69 years old and females. The proportion of patients filling in a prescription for mono-bronchodilators or inhaled corticosteroids decreased in the observational period, while dual bronchodilators became available, and their use gradually increased. The adherence to maintenance inhaled therapies was good (>180 days/year) only in approximately half of the population (51.6% in 2019). The number of patients filling in prescriptions for oral theophylline did not decline in the observation period (32% in 2019). Discussion: Between 2011 and 2019, the number of COPD patients on maintenance inhaled therapy did not reach that of the registered patients. Adherence to maintenance inhaled treatment is inadequate in a significant portion of patients. The rate of patients taking oral theophylline is high. Conclusion: Improvement of adherence to maintenance inhaled therapies is essential for a better prognosis of COPD in Hungary. Orv Hetil. 2024; 165(9) 338­345.
