Objective The purpose of this study is to investigate trends in the incidence of Subarachnoid Hemorrhage (SAH) in South Korea from 2006-2009. Methods We used the national health claim database managed by Health Insurance Review and Assessment Service (HIRA), which contains all hospital records of every Korean citizen. Patients with SAH were defined as ICD-10 codes (I60) with a hospitalization period of 14 days or death within 14 days of hospitalization. We evaluated trends in the incidence of SAH over a 4-year period using the Cochran-Armitage trend test. Results We identified 35,263 SAH patients among adult patients (≥18 years old) from 2005-2009. Age-adjusted SAH incidence rates decreased from 13.4 in 2006 to 12.4 in 2009 per 100,000 men (p=0.0025) and women also showed a decrease from 19.4 to 17.3 per 100,000 (p<0.0001). However, this decreasing pattern was not shown in patients under 50 years of age. SAH incidence showed gender differences dependent upon age; men who were 40 years old or less had a higher incidence than women. Conclusions The age-adjusted incidence rates of SAH were slightly decreased in South Korea. Further research should be conducted to identify the clinical risk factors to reduce SAH incidence rates even more, especially in younger people.
