Aim: To reveal the clinical and functional features in patients with COPD in Russian primary health care.

Methods: At stage 1, COPD risk factors were assessed among persons with respiratory symptoms (n=525). Stage 2 included screening spirometry. At stage 3, patients with COPD were examined to determine clinical and functional features. The COPD group included 150 patients in age from 45 to 81 years (56.1±2.3 years). According to the GOLD classification, patients were divided into the following groups: group A – 59 patients (39.3%), group B – 30(20%), group C – 29(19%) and group D – 32(21.7%).

Results: Mild to moderate COPD was registered in 62% of cases. 88(58.7%) had few symptoms of the disease (mMRC-0-1, CAT <10 points), 62(41.3%) had many symptoms (mMRC-0-1, CAT ≥10 points). There is a correlation between the rate of exacerbations and severity of COPD (r=0,56, p<0,05 ). Most of the patients without exacerbations belonged to group A (45.4%). There were no significant demographic differences between the groups in terms of age, gender, and smoking status (p>0.05). 58.3% of COPD patients had a 1point mMRC score and 41.7% of patients had a score of more than 2.

Conclusion: The study revealed a high prevalence of COPD between adults with mild to moderate severity.
