Persistence, defined as the absence of dispensing gaps of >90 days, was measured at 12 months. Exacerbations were compared between persistent and non-persistent patients during follow-up after patient matching and adjustment for confounding factors. COPD-related HRU during follow-up was described.Results: Among 4020 patients with COPD, 2164 initiated a specific therapy. Of these, 54.4% stopped treatment within 12 months. Persistence with all COPD therapy regimens was low, particularly for inhaled corticosteroid (ICS; ... |
