Continuing to Confront COPD International Patient Survey: methods, COPD prevalence, and disease burden in 2012–2013

Abstract

This survey, representing 12 countries, showed similar rates of estimated COPD prevalence across countries that were higher than those reported a decade ago in the original Confronting COPD International Survey. A significant burden of COPD was demonstrated by symptoms and health care-resource use, similar to that reported in the original survey.
