The frequency of hip fractures associated with aging of the population is declining in many countries. Even in Japan, where this frequency has been increasing continually, a shift to decreasing frequency has been noted in recent reports. The objective of this study was to investigate the effects of this decrease and to estimate the number of hip fracture patients and the resulting reduction in national medical care expenditures. The differences in the number of patients were estimated by multiplying the population for each sex and each age group by the fracture rates before the decrease (2007) and after the decrease (2012). Total reduced cost was calculated by multiplying the treatment cost required for hip fracture and the annual medical cost of nursing care. The estimated number of hip fracture patients decreased by approximately 4000 in the elderly female population, and the resulting reduction in medical costs was approximately US$280 million. The number of patients with hip fractures has decreased in elderly Japanese women; as a result, the medical costs for treatment and nursing care might decrease.
在许多国家，与人口老龄化相关的髋部骨折发生率正在下降。即使在日本，该发生率一直在持续上升，但最近的报告显示已出现下降趋势。本研究的目的是调查这种下降的影响，并估算髋部骨折患者的数量以及由此导致的国家医疗支出减少情况。通过将每个性别和年龄组的人口数乘以下降前（2007年）和下降后（2012年）的骨折发生率来估算患者数量的差异。通过将髋部骨折所需的治疗费用与每年的护理医疗费用相乘来计算总成本的减少量。老年女性人群中髋部骨折患者的估计数量减少了约4000人，由此导致的医疗费用减少约为2.8亿美元。日本老年女性髋部骨折患者数量减少；因此，治疗和护理的医疗费用可能会降低。
