Bottom Line: Official medical statistics data and the data collected from the Global Alliance against Chronic Respiratory Diseases program 2011 among 15,000 inhabitants of the region aged 18 years and older were analyzed.Because of this, there is an increase in the index of potential years of life lost.This, in turn, may reduce the overall burden of the disease for the population of the region.

ABSTRACT

Background: Krasnoyarsk region is a territory with the widespread risk factors for chronic obstructive pulmonary disease (COPD) such as tobacco smoke, air pollution, and occupational exposure. An assessment of COPD prevalence based on medical diagnosis statistics underestimates the true COPD prevalence. This study aims to evaluate how medical examinations may increase the accuracy of estimates of COPD prevalence.

Methods: True COPD prevalence was estimated as a number of patients with the established disease diagnosis supplemented by the additional disease cases detected during medical examinations per 1,000 inhabitants of the region. Official medical statistics data and the data collected from the Global Alliance against Chronic Respiratory Diseases program 2011 among 15,000 inhabitants of the region aged 18 years and older were analyzed.

Results: This study revealed the COPD cases without official medical diagnosis. The true prevalence of COPD is estimated to be two times higher than the prevalence estimates based on medical diagnosis statistics.

Conclusion: Undiagnosed and untreated cases of COPD result in severe COPD forms as well as addition of severe comorbidities. Because of this, there is an increase in the index of potential years of life lost. Conducting special medical examinations may increase the number of COPD cases detected at the early stages of the disease. This, in turn, may reduce the overall burden of the disease for the population of the region.

f1-copd-10-1781: The distribution of the patients with an established COPD diagnosis and the additional disease cases (per 100,000) by age groups.Notes: (A) For men and (B) for women.

Mentions: In Figure 1, we demonstrate the distribution of the number of patients with an established COPD diagnosis and the additional disease cases per 100,000 by age group: Figure 1A, distribution for men and Figure 1B, distribution for women. The total number of men with COPD is higher than the total number of women with COPD for both established and additionally diagnosed cases of COPD due to the fact that harmful factors affect more men than women (smoking, occupational exposure, etc). From this figure, we can conclude that the true prevalence of COPD is maximal in the 61–70 age group for men and in the 51–60 age group for women. There are no established COPD diagnosis cases for the age groups 18–30 and 31–40 for both men and women. This may occur due to the fact that clinical symptoms of COPD are not yet present in these age groups. Identification of patients (residents of the Krasnoyarsk region) with unestablished COPD diagnosis is the main contributor to the cases of COPD in the age groups 18–30 and 31–40 for men and the age group 31–40 for women.
