Triple therapy (long-acting muscarinic antagonist [LAMA] plus long-acting beta2-agonist [LABA] plus inhaled corticosteroid [ICS]) is recommended by the Global initiative for chronic Obstructive Lung Disease (GOLD) for moderate-to-severe chronic obstructive pulmonary disease (COPD) with a history of frequent and/or severe exacerbation(s) and dyspnea while using dual bronchodilators. However, many patients receive triple therapy contrary to these recommendations. This study describes factors associated with GOLD-discordant triple therapy initiation. This retrospective analysis included patients aged 40 and above, with ≥1 COPD diagnosis, who initiated triple therapy (initiation=index date) during the period January 1, 2014 to December 31, 2018 and had ≥12 months pre-index continuous enrollment (baseline). Triple therapy comprised ≥30 days of overlapping LAMA, LABA, and ICS treatments (open triple therapy), or single-inhaler fluticasone furoate/umeclidinium/vilanterol (closed triple therapy). Cohorts were defined based on the absence of baseline maintenance medication use ("maintenance-naïve"), and/or exacerbations ("exacerbation-discordant"), or "dual-discordant" (discordant on both measures). All triple therapy initiators, overall and for each cohort, were described, and predictors of GOLD-discordant triple therapy initiation were identified. Among 21,711 triple therapy initiators, 34.4% were maintenance-naïve, 61.9% exacerbation-discordant, and 22.2% dual-discordant. Triple therapy initiation appeared to increase during the period 2016 to 2018. In 2018 alone, 31.9% and 58.3% of open triple therapy patients were maintenance-naïve and exacerbation-discordant, respectively, versus 37.6% and 64.4% of closed triple therapy patients. Closed triple therapy initiators had 1.65 times greater risk of dual discordance than open triple therapy initiators. Exacerbation-discordant patients initiating closed triple therapy were 1.61 times more likely to be maintenance-naïve than those initiating open triple therapy. A substantial proportion of COPD patients initiating triple therapy do not meet GOLD recommendations regarding exacerbation history and/or prior maintenance therapy. Compared with open triple therapy, closed triple therapy initiators were more likely to be dual discordant.
