Study Population
The base cohort will consist of all patients with a diagnosis of COPD from 1 January 1995 until 31 December 2015 who subsequently received at least one prescription for a long-acting bronchodilator, either LABA or tiotropium, or for an inhaled corticosteroid, alone or in combination, from 1 January 2002 until 31 December 2015.
