Asthma prescribing trends, inhaler adherence and outcomes: a Real-World Data analysis of a multi-ethnic Asian Asthma population.

Inhaled corticosteroid (ICS) is the mainstay therapy for asthma, but general adherence is low. There is a paucity of real-world inhaler prescribing and adherence data from Asia and at the population level. To address these gaps, we performed a real-world data analysis of inhaler prescribing pattern and adherence in a multi-ethnic Asian asthma cohort and evaluated the association with asthma outcomes.
