title: [Change of the patient characteristics among adult asthmatics hospitalized due to acute exacerbation].
abstract: BACKGROUND
  We analysed the patient characteristics among adult asthmatics hospitalized to our hospital to clearfy the residual problems in the prevention and treatment of asthma.
  
  
  METHODS
  We identified the adult asthmatics hospitalized to our hospital during the period A: Jan 2004-Dec 2005 and the period B: Jan 2009-Dec2010 and analysed retrospectively around age, smoking history, and the use of ICS (including combination medicine) and so on.
  
  
  RESULTS
  The total patient numbers were A: 161 and B: 88, decreasing to almost half. The rates of the patients older than 65 years were equivalent between the 2 groups. Categorized according to age, in the group <65 years old, the rates of ICS use were A: 22.9% and B: 35.8% and the current smoking rates were A: 42.7% and B: 49.1% respectively. In the group 65≤ years old, the rates of ICS use were A: 46.2% and B: 48.6%, and the current smoking rates were A: 19.7% and B: 22.9%.
  
  
  CONCLUSIONS
  In the group <65 years old, ICS has become more popular but smoking rate has increased among hospitalized adult asthmatics. It is estimated that smoking leads to reduce the effect of ICS and the strategy of smoking cessation will be needed to reduce acute exacerbations. In the group 65≤ years old, ICS is relatively more popular than youth and smoking rate is limited. Asthma among elder people may be refractory and more efficient strategies must be required.
