Abstract
UNLABELLED: Incidence of hip fracture increased in Korean populations over age 50 between 2008 and 2012, and the number of fractures was predicted to increase by 1.4 times by 2025. This is important information for public health planning. INTRODUCTION: The purposes of this study were to evaluate the trends in the incidence and mortality of hip fracture between 2008 and 2012 and predict the number of hip fractures in Korea through 2025 using nationwide claims data. METHODS: The data managed by the National Health Insurance Service were used to identify the hip fractures in patients aged >50 years between 2008 and 2012. Projections of hip fractures were conducted using the Poisson distribution from 2016 to 2025 in Korea. RESULTS: The incidence of hip fractures (per 100,000) increased by 14.1 % over the 5 years of the study, by 15.8 % in women and 10.9 % in men; the older age group showed a steep rise and shift in the incidence from 2008 to 2012. The cumulative mortality rates at 1 year after hip fractures were 17.2 % (3575/20,849) in 2008 and 16.0 % (4547/28,426) in 2012. Overall standardized mortality ratios (SMRs) for hip fracture were higher in men (11.93) than in women (11.22) and were higher than those in the general population in all age groups. In 2016, the total number of hip fractures was estimated to increase an overall of 1.4 times by 2025. CONCLUSIONS: The incidence of hip fracture continues to increase, and the related mortality is still high, although it has decreased over time. The socioeconomic burden of hip fracture is expected to increase in Korea along with the increased estimated number of fractures. Nationwide strategies should include attempts to reduce the future socioeconomic burdens of hip fractures.
