Introduction
The international standard for the recognition and treatment of chronic obstructive pulmonary disease (COPD) is guided by a regularly updated set of criteria developed by the Global Initiative for Chronic Obstructive Lung Disease (GOLD).

Aim
To investigate the impact of updated COPD management guidelines from 2007 to 2017 (GOLD 2007, GOLD 2011 and GOLD 2017) on the assignment of patients into individual therapeutic groups, examining both individual and population dimensions.

Material and methods
Each of 500 randomly chosen primary care physicians in Poland provided information on 10 individual COPD patients (disease history, clinical status, treatment and pharmacotherapy). This data was used to simulate the consequences of the implementation of the GOLD 2007, 2011 and 2017 guidelines.

Results
A group of 298 physicians of 500 approached provided information on 2597 patients (64.2% males) aged 29–96 (61.6 ±11.1 years). Based on GOLD 2007 guidelines, most patients (56.7%) presented a severe stage of COPD. GOLD 2011 updates would significantly increase the proportion of patients with the most severe stage of disease, and this group would be predominantly classified as moderate or severe in GOLD 2007. The implementation of GOLD 2017 guidelines would result in a significant migration of patients towards the lightest (category A) form of the disease.

Conclusions
Updates to the GOLD 2007 COPD guidelines for GOLD 2011 and 2017 would have a significant impact on the classification of patients for particular therapeutic groups. As a result of the migration of patients to particular therapeutic groups, the pharmacological treatment would also change.
