Nationwide use of inhaled corticosteroids by South Korean asthma patients: an examination of the Health Insurance Review and Service database

摘要

Background: Previous studies have found that the prescription rates of inhaled corticosteroid (ICS) were considerably low although it is recommended as the optimal asthma treatment. The aim of this study was to analyze the current status of ICS prescription for asthma patients in the South Korea. Methods: We evaluated quality assessment data based on nationwide Health Insurance Review and Service (HIRA) database from July 2013 to June 2014. ICS prescription rates in asthma patients were analyzed by types and specialty of medical institutions. Also, we graded medical institutions by their ICS prescription rate. In addition, ICS prescription rates were calculated by patient gender, age, and insurance type. Results: This study included 831,613 patients and 16,804 institutions in the analysis. The overall mean ICS prescription rate was 22.58%. Tertiary hospitals had the highest mean prescription rate (84.16%) whereas primary healthcare clinics had the lowest (20.71%). By specialty, internal medicine physicians prescribed ICS more frequently compared to other specialists. Of all, 47.17% of medical institutions prescribed ICS to 80% of asthma patients. Also, we found that female and patients with age 90 or Conclusions: The ICS prescription rate was found to be inadequate, given the importance of ICS as an asthma treatment. The prescription rates were especially low in primary healthcare clinics, and by specialists in fields other than internal medicine.
