Abstract
COPD patients prescribed inhaled corticosteroids (ICS) outside guidelines should be targeted for ICS withdrawal. Within a primary care population of 209,618 we used a combination of digital search algorithm, individual record review, and clinical review to identify COPD patients suitable for a trial of ICS withdrawal. At most, 39% of COPD patients with mild or moderate airflow limitation prescribed ICS were suitable for withdrawal according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. Recurrent exacerbations and reversible airway obstruction were the main reasons for patients' unsuitability for withdrawal. Identifying COPD patients in whom ICS withdrawal should be considered presents a challenge to primary care clinicians.
