Anemia increases mortality in patients with chronic obstructive pulmonary disease (COPD), but its effects on mortality and survival time for different levels of airflow limitation severity are unclear. Our goal was to investigate the effects of anemia on survival time and mortality in COPD patients with varying degrees of airflow limitation. We looked at 300 consecutive COPD patients in the past. Their demographic information, Charlson comorbidity index, previous early (30 days) and late (>30 days) hospitalizations, blood counts, and post-bronchodilator spirometric values were all recorded. They were contacted by phone to check on their vital status, and their mortality rates were calculated. Anemic patients had a mean overall survival time of 31.9 2.8 months and normal patients had a mean overall survival time of 41.7 2.1 months (p=0.001). Their 1-year and 2-year mortality rates are higher. Age, Charlson comorbidity index, BMI, FEV1%, anemia, MCV, hemoglobin, serum creatinin, and early and late hospitalizations all had an impact on mortality. BMI, anemia, and FEV1% remained risk factors for death. Anemic group 2 patients had a higher mortality rate than groups 3 and 4. Anemic patients in groups 2 and 4 had shorter survival times. Anemic COPD patients have higher 1-year and 2-year mortality rates. Mortality is affected by age, Charlson comorbidity index, BMI, FEV1%, anemia, MCV, hemoglobin, serum creatinin, and early and late hospitalizations. BMI, anemia, and FEV1% remained risk factors for death. Anemic group 2 patients have a higher mortality rate than groups 3 and 4. Anemic patients in groups 2 and 4 have shorter survival times.
