• Resumen

  • Background Initiation of treatment of COPD with a combination of a long-acting beta-agonist (LABA) and an inhaled corticosteroid (ICS) is frequent irrespective of the risk of exacerbations.

    Method We performed a retrospective, population-based, observational study aimed at comparing the effectiveness of a LABA/long-acting antimuscarinic agent (LAMA) and LABA/ICS in patients with COPD over a one-year follow-up. Data were obtained from an administrative healthcare claims database. The primary outcome was the risk of first exacerbation. A sensitivity analysis was conducted in a propensity-score matched population.

    Results The population consisted of 14,046 COPD patients; 11,329 (80.6%) initiated LABA/ICS and 2717 (19.4%) LABA/LAMA. The matched population included 1650 patients in each arm. During follow-up, 69.6% patients in the LABA/ICS group and 64.4% in the LABA/LAMA group presented an exacerbation. The mean time to the first exacerbation was 6.03 months (95% confidence interval (CI): 5.94–6.12) for LABA/ICS and 6.4 months (95%CI: 6.21–6.59) for LABA/LAMA; p<0.001. The time to scalation to triple therapy was also significantly prolonged in LABA/LAMA. Similar results were obtained in the matched population. LABA/LAMA was associated with a significantly lower risk of exacerbations and escalation to triple therapy compared to LABA/ICS, except in patients with frequent exacerbations and high blood eosinophils in which no differences were observed in the time to first exacerbation.

    Conclusion Initiation of treatment with LABA/LAMA was associated with a lower risk of exacerbation and escalation to triple therapy compared to LABA/ICS in the majority of patients with COPD in primary care.
