The Burden of Alpha-1 Deficiency-Related COPD in Participants of the WebMD Lung Health Check

The COPD Foundation partnered with WebMD in 2009 to sponsor the Lung Health Check, an online tool that collect information on COPD and the impact of COPD on patients. In 2010 and 2011 nearly 600,000 people, 177,000 of whom had a COPD diagnosis, completed the survey. The COPD Foundation was able to negotiate with WebMD and obtain the raw data files for analysis. Among the over 177,000 subjects with a COPD diagnosis, 1,619 (0.9%) reported that they have Alpha-1 Antitrypsin deficiency. This will be an analysis comparing the Alpha-1 patients to the other COPD patients on a number of measures (lung function, quality of life measures, ability to work, etc.). This analysis will give new insights into how Alpha-1 patients are dealing with their disease and, unique in this database, be able to compare them to the broader COPD patient population
