Abstract


Background: Chronic obstructive pulmonary disease (COPD) is a preventable, treatable and progressive disease characterized by persistent airflow limitation. Influenza is a common respiratory infection in winter. Viral infection especially influenza is the most common cause of COPD exacerbation. The objective of this study is to determine the prevalence of influenza vaccination in patients presented with COPD exacerbation.

Methods: This population-based cross sectional study was carried out in the department of Pulmonology Ayub Teaching Hospital Abbottabad. All patients diagnosed with COPD, irrespective of duration of disease and both males and females were included in the study. History of influenza vaccination in the past 3 years was retrieved fromall these patients.

Results:  Among 150 patients 90 (60%) were male and 60 (40%) were female. Mean age was 60.5 (±10.3 SD) years in males and 53 (±8.4 SD) years in females. Overall prevalence of influenza vaccination was 26.7%. This was more prevalent in patients with severe and more severe disease according to FEV1 (62.5%). Rate of vaccination was higher in males and in advance disease.

Conclusion: Influenza vaccination rate is not optimal in patients with COPD although it is recommended forCOPDpatients and this might be a contributing factor to increased rate of acute exacerbation inCOPDpatients.
