Time Perspective: Prospective
|Official Title:||Validation of PROMIS Banks With COPD Exacerbations|
|Study Start Date:||July 2008|
|Study Completion Date:||June 2009|
|Primary Completion Date:||June 2009 (Final data collection date for primary outcome measure)|
Patients who are stable have not had a COPD exacerbation in the past 2 months.
Patients with an exacerbation have been diagnosed and started on treatment for an exacerbation within the past 3 days.
This is a prospective longitudinal study of adult patients with chronic obstructive pulmonary disease (COPD) who will be enrolled when their COPD is considered clinically stable or during an acute exacerbation. This design will allow both within-person and between-person comparisons by exacerbation experience. Comprehensive clinical and patient-reported assessments will be performed at baseline and at 3 months (end of study). Subsets of items will be 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 will be interviewed at the end of the study to assess content validity of PROMIS items in this patient population.
With such a study design, we will be able to evaluate the validity of the PROMIS items in this patient population under acute and stable conditions and evaluate responsiveness of several PROMIS item banks under conditions of known change in an underlying chronic disease. We will also evaluate stability of sub-domains that are not hypothesized to change with COPD exacerbations.
