다국어 초록 (Multilingual Abstract)

Purpose : During the past two decades in Korea, the prevalence rate of childhood asthma has been increased, and also there has been a significant evolution in the management of asthma. In 1994, a guideline for the diagnosis and treatment of asthma was established. This study was designed to investigate a real picture of clinical practice in the management of childhood asthma. Methods : This survey was conducted with data on 24 items of questionnaires from pediatricians working in private clinics, general hospitals, and university hospitals. We investigated the age distributions, severity of asthma, educational levels, management of asthma, and current trends of medication. Results : 1) In age distribution, childhood asthma was most prevalent in 3-5 years old age group(30-40%), followed by 2 years old age group, and was least prevalent in 10-15 years old age group. 2) The number of patients with cough variant asthma was about 10% of all childhood asthma. 3) A period of 5-10 minutes was the most common period consumed for the explanation of child asthma during each medical practice. Cases recording symptom diary and cases monitoring PEFR(using peak flow meter) were less than 10% each. 4) With regard to the use of β2 agonist in the treatment of acute asthmatic attack, rate of using oral drugs and nebulizer or inhalers of β2 agonist are similar in the university hospitals, but the rate of using oral drugs was over 80% in private clinics. 5) With regard to the use of anti-inflammatory drugs in the management of chronic asthma, nebulizer or inhaler therapy was the first-line choice in the university hospitals(rate over 60-90%), oral drugs were main therapy in private clinics. The administration of anti-allergic medication as a preventive measures was recommended in about 40-50%, and ketotifen was used most frequently. 6) Immunotherapy was being performed in about 10% of childhood asthma patients. Conclusion : Childhood asthma was most prevalent in the age group under 5 years and severity was mostly mild. For the management of childhood asthma, the education and control for asthma are still insufficient and previously published guidelines have been inappropriately used in practical field.
