subject

description

Abstract Introduction DACCORD is an ongoing, longitudinal, non-interventional study within the German COPD National Prospective Registry. This manuscript describes the baseline characteristics of the first 5924 participants, recruited between November 2012 and November 2013. Methods The main inclusion criteria are a physician diagnosis of COPD, age ≥40 years, and initiating or changing COPD maintenance medication. Data collected included: Demographic and disease characteristics; prescribed medication; symptoms; COPD Assessment Test (CAT); modified Medical Research Council dyspnoea score (mMRC); exacerbations; comorbidities; and forced expiratory volume in 1 s (FEV 1 ). Results Approximately 60% of the population are male, with mean age of 65.7 years and FEV 1 61.6% predicted. On entry to the study the majority of patients reported symptoms, most commonly exertional dyspnoea (85.9%) and cough (65.7%). According to GOLD 2010, 48.6% of patients were classified as GOLD II. GOLD 2011 classification was influenced by the symptoms criterion: 43.7 and 45.3% of patients were classified as GOLD B or D using CAT, compared with 26.4 and 34.0%, respectively, using mMRC. The majority of patients were receiving a LAMA-containing regimen, with 39.4% overall receiving ICS. A total of 78.3% of patients reported at least one comorbidity, most commonly cardiovascular. Conclusion In conclusion, DACCORD is a large, prospective, non-interventional study that provides an informative and intriguing picture of the typical COPD patient in Germany.
