Abstract
Background: Polycythemia, traditionally thought to be highly prevalent in COPD, occurs less frequently nowadays with more rigorous correction of hypoxaemia. Conversely, recent reports suggest that anaemia in patients with COPD is highly prevalent and associated with increased mortality. The purpose of the present study is to determine the prevalence of abnormalities in Hb levels in patients with COPD attending a tertiary health care centre in Kerala, as well as to explore the associations between Hb levels and clinical outcomes.
Objectives: To study the proportion of anaemia in patients with chronic obstructive pulmonary disease attending a tertiary health care centre in Kerala
Methods: This was a cross-sectional study done among 120 patients with COPD. Samples were selected by consecutive sampling method, data collected using a proforma and it was analyzed using SPSS.
Results: In this study, 120 COPD patients diagnosed based on GOLD clinical criteria were recruited. 53 patients were in anemic group while 67 patients in nonanemic group. The prevalence of anemia in COPD patients in the present study was 44.2%. The mean hemoglobin levels in anemic group were 10.87 ±1.73g/dl, whereas in nonanemic group, it was 14.57 ± 1.6 g/dl. It was found that the most common morphological type of anaemia was normocytic normochromic (49.1%) followed by microcytichypochromic (37.7%).
Conclusion: Presence of anaemia is significantly associated with worse hospital outcome in the form of increased ICU admission, increased requirement of NIV and mechanical ventilation and increased mortality.
Keywords: COPD, anaemia, haemoglobin, mortality, exacerbation.
