The GOLD 2011 recommendations for chronic obstructive pulmonary disease (COPD) introduce a new classification system to optimize treatment in individual patients. Except for FEV,, this classification incorporates breathlessness measurement using modified medical research council questionnaire (mMRC) or the COPD assessment Test (CAT) and the number of exacerbations. The aim of our study was to compare the GOLD 2010 and GOLD 2011 COPD. ⋯ The new classification according to GOLD 2011 lets on optimizations of the treatment, in most cases of COPD patients but in clinical practice, there may be problems with the classification of the patients with severe airway obstruction without frequent exacerbations and especially those with mild/moderate airflow limitation and frequent exacerbations.
