Background: In 2009, the outbreak of pandemic influenza A(H1N1) has broad societal and financial impact. The medical costs of influenza including treatment, diagnosis and antiviral drugs were increased considerably. In this study, we evaluated the health economic impact of the pandemic by comparing medical costs for 2007-2010 in the Republic of Korea(ROK).

Methods: All legal residents of ROK are covered by the Korea National Health Insurance program, and their medical care utilization is reviewed by the Health Insurance Review Agency. Patients included in our analyses were defined as those with influenza diagnosis (ICD-10: J09-11). We defined the epidemic period is from April, 2009 to March, 2010. And the medical costs of epidemic period compared to the previous periods (Two years ago: April, 2007-March, 2008, A year ago: April, 2008-March, 2009).

Results: The total number to outpatient was 4,769,070 in epidemic period, 424,077 in a year ago, and 527,510 in two years ago. The total number to inpatient was 131,267 in epidemic period, 9,208 in a year ago, and 7,324 in two years ago. The number of patient was increased more than 10 times. In 15—19 year old group, the number of outpatient was increased highest (33.5 times), while the lowest increase (2.4 times) was happened in old age group. The highest increase (42.5 times) of number of inpatient was happened in 15-19 year old group, however the lowest increase (9.3 times) was in 0-4 year old group. In epidemic period, the sum of medical costs for outpatient was 284.6 billion Korean won (₩) and that of inpatient was ₩ 106.8 billion. The sum of medical costs in a year ago was ₩ 5.5 billion for outpatient and ₩ 5.2 billion for inpatient. In two years ago, the sum of medical costs was ₩6.6 billion for outpatient and ₩ 4.1 billion for inpatient.

Conclusion: Due to the pandemic influenza A (H1N1), it was the huge increase of patient and medical costs in ROK. And the increase was over 10 times for number of patient and approximately 20-50 times for medical costs.
