Title: A Multicentre 3 Year Longitudinal Prospective Study to Identify Novel Endpoints and Compare These With Forced Expiratory Volume in 1 Second (FEV1) for Their Ability to Measure and Predict COPD Severity and Its Progression Over Time
Brief Summary: This is a 3 year longitudinal study to identify novel endpoints and compare these with standard measures such as forced expiratory volume in 1 second (FEV1) for their ability to measure and predict COPD (Chronic Obstructive Pulmonary Disease) severity and its progression over time. Control subjects (smokers and never smokers) will be recruited as comparators with the COPD subjects.

A: Inclusion Criteria:

Population to be studied

The study population consists of VA patients with COPD who receive some of their medical care at Veterans Affairs medical centers and were hospitalized for COPD in the last 12 months. To ensure that patients enrolled in the study receive regular care at the participating VA, we will include only patients enrolled in either the primary care or pulmonary clinic at the VA medical center and were seen at least once in the last year. This criterion should not significantly decrease the number of eligible patients because 90% of patients admitted for COPD in the VA had at least 1 outpatient visit to the VA primary care clinic in the year prior to their hospitalization based on data from the VA OPC in FY03.

Inclusion Criteria:

1. Diagnosis of COPD confirmed by all of the following:

   1. FEV1/FVC \< 0.70
   2. FEV1 \< 80%
   3. Age \> 40 years
   4. A current or past history of cigarette smoking (\> 10 pack-years)
2. COPD hospitalization in the previous year
3. Receives care at participating VA medical center

   1. Enrolled in either primary care or pulmonary clinic at the VA
   2. Seen at least once in the past year in either primary care or pulmonary clinic
4. No COPD exacerbations in last 4 weeks
5. English-speaking
6. Access to telephone

Exclusion Criteria:

1. Primary clinical diagnosis of asthma
2. Medical conditions affecting the ability to participate in the study such as:

   1. Comorbid illness likely to limit life expectancy \< 1 year
   2. Decompensated heart failure
   3. Dementia
   4. Uncontrolled psychiatric illness
3. Participation in another clinical intervention trial in the previous 30 days
