Abstract

BACKGROUND: Asthma management guidelines provide recommendations for the optimal control and goals of management. This survey was performed as a part of Asthma Insights and Reality in Asia-Pacific Region (AIRIAP) study to assess the current levels of asthma control reported by patients, which partly reflect the extent to which guideline recommendations are implemented.
METHODS
From September to December 2000, current asthma patients were identified by random door-to-door visits by screening 13,988 households in Seoul, Korea. Designated responders were interviewed on asthma control, symptom severity, activity limitations and healthcare utilization.
RESULTS
Current asthmatics were identified in 1,024 households, and 401 patients completed the survey. Daytime asthma symptoms were reported by 52%, and 26% reported sleep disturbance caused by asthma at least once a week in the past 4 weeks. In the past 12 months, 14% had been hospitalized, 6% attended emergency departments, and 30% made unscheduled emergency visits. Patient's perception of asthma control was different from their actual asthma control. Current use of an inhaled corticosteroid was reported by only 0.2% of responders. Absence from school and work in the past year was reported by 14% of adults and 7% of children.
CONCLUSIONS
The current level of asthma control in Korea falls markedly short of the goals specified in international guidelines for asthma management. Management according to the guideline and patient education is important for the optimal control of asthma. Development of practically easy asthma management guideline for primary physician may be also important for its implementation.
