PROMIS 1 Wave 2 Chronic Obstructive Pulmonary Disease (COPD)

This is a prospective, longitudinal study of adult patients with Chronic Obstructive Pulmonary Disease (COPD). Patients were enrolled when their COPD was considered clinically stable or during an acute exacerbation. This design allowed both within-person and between person comparisons by exacerbation experience. Comprehensive clinical and patient-reported assessments were performed at baseline and at 3 months (end of study). Subsets of items were administered by interactive voice response (IVR) over the course of the study to measure changes in key symptoms over the course of recovery from an exacerbation. A subset of patients were interviewed at the end of the study to assess content validity of PROMIS items in this patient population.
