Objective: The present study intended to determine the risk factors of severe exacerbation in chronic obstructive pulmonary disease patients even though managed by pulmonologists on a regular basis. Material and Method: A retrospective case-controlled study was conducted at the chest clinic, Maharaj Nakorn Chiang Mai Hospital from 1st August 2009 to 31stJuly 2010. The clinical relevant data for acute exacerbation (age, sex, co-morbidity, severity of COPD, COPD medication, annual influenza vaccination, compliance with inhaled drug use, chest radiographic abnormality, and long-term oxygen therapy) were compared between severe AECOPD and stable COPD patients by logistic regression analysis. Results: Out of 137 COPD patients, 17 (12.4%) had severe AECOPD with 29 episodes (21.2%). Six risk factors were identified, two modifiable and four non-modifiable. The two modifiable risk factors were annual influenza non-vaccination (odds ratio [OR] 27.79; 95% confidence interval [CI], 2.29-337.66, p-value = 0.01) and improper use of inhaled devices (OR 9.94, 95%CI 1.07-92.54, p-value = 0.04). The four non-modifiable risk factors were age <60 yrs (OR, 10.67; 95%CI, 1.92-59.31, p-value = 0.01), hypertension (OR, 4.03; 95%CI. 1.05-15.44, p-value = 0.04), enlarged pulmonary trunk as demonstrated by chest radiograph (OR, 8.61; 95%CI, 1.49-49.85, p-value = 0.02), and long-term oxygen therapy (OR, 7.09; 95%CI, 1.36-37.00, p-value = 0.02). Conclusion: Six risk factors of severe AECOPD among patients whom were provided regularly managed by pulmonologists were identified; two of them, annual influenza non-vaccination and improper use of inhaled devices, could be potentially modified.
