Trends of incidence and 1-year mortality of vertebral fractures in Korea using nationwide claims data
摘要
Using nationwide data from 2006 to 2022, we found that vertebral fracture rates in Korea plateaued recently, with a slight decline during COVID-19, while one-year mortality remained unchanged. These findings highlight the growing burden of osteoporotic fractures and underscore the need for targeted prevention and management strategies.
PurposeOur purposes were to evaluate the trends in the incidence and mortality of vertebral fractures and the effects of COVID-19 between 2006 and 2022 in Korea, using nationwide data from the National Health Insurance Service (NHIS).
MethodsA nationwide dataset was evaluated to identify all new visits to medical institutes for vertebral fractures in men and women aged 50 years or older between 2006 and 2022. Patients were defined using ICD-10 diagnosis codes combined with procedure codes to ensure specificity. The incidence and 1-year mortality rates were calculated. The age- and sex-standardized incidence rates were calculated using the 2020 Korean population as the reference, which demonstrated a plateauing trend in recent years.
ResultsWhile the number of vertebral fractures increased, the incidence plateaued around 2010. Men and women respectively experienced 17,872 and 66,980 vertebral fractures in 2006 and 43,901 and 136,826 in 2022. The crude incidence of vertebral fractures changed from 319.4/100,000 to 408.5/100,000 person-years in men and 1011.1/100,000 to 1155.5/100,000 person-years in women between 2006 and 2022. The 1-year mortality rate after vertebral fractures gradually decreased from 6.5% in 2006 to 6.2% in 2021. There was no remarkable change of mortality during the outbreak of COVID-19. The overall mortality of vertebral fractures in men was about twice as high women as during the whole study period.
ConclusionThe incidence of vertebral fractures remained relatively stable after 2010 in Korea. During the outbreak of COVID-19, incidence of vertebral fractures decreased while the mortality after vertebral fractures was unaffected.
