Prevalence of anemia and its impact on mortality in patients with acute exacerbation of chronic obstructive pulmonary disease in a developing country setting.

Chronic Obstructive Pulmonary Disease (COPD) is going to be the third most common
cause of death worldwide. The natural course of COPD is interrupted by acute
exacerbations (AECOPD) with an overall mortality rate of 10%. Anemia is a well­known
independent predictor of mortality in several chronic diseases. Little is known about the
impact of anemia on mortality in AECOPD. The aims of this study were to determine the
prevalence of anemia in AECOPD patients and its impact on mortality in a developing
country setting. We retrospectively studied 200 hospitalized patients with AECOPD (100
died in hospital and 100 survived) in Imam Khomeini teaching hospital, Urmia, Iran.
Prevalence of anemia between deceased and surviving patients compared by using
