| アブストラクト | Using the nationwide health insurance claims database in Japan, we estimated total annual medical expenditures for fragility hip fracture across the population at 329.2 billion yen (2.99 billion US dollars). Long-term care expenditures were not included. Fragility hip fracture imposes a considerable health economic burden on society in Japan. PURPOSE: Fragility hip fracture imposes a substantial health economic burden on society globally. We aimed to estimate medical expenditures for fragility hip fracture using the nationwide health insurance claims database in Japan. METHODS: We included adults aged 60 and over without prior hip fracture who were admitted for fragility hip fracture (i.e., femoral neck or extracapsular) between October 2014 and October 2015 (13 months). Fragility hip fracture was identified through newly assigned disease codes for fracture and procedure codes associated with the fracture. As a proxy for medical expenditures per patient, incremental payments were calculated (i.e., the difference between the total payments 6 months before and after fragility hip fracture). The total payments included health insurance reimbursements and copayments for inpatient and outpatient services. Long-term care expenditures were not included in this study. RESULTS: We identified 142,361 individuals (28,868 male and 113,493 female) with fragility hip fracture. Mean medical expenditures for fragility hip fracture per patient were 2,550,000 yen ( yen) (23,180 US dollars [$]; yen110 = $1) in male and yen2,494,000 ($22,670) in female patients, respectively. Total annual medical expenditures for fragility hip fracture across the population were 329.2 billion yen (2.99 billion US dollars): 67.96 billion yen (620 million US dollars) in male and 261.24 billion yen (2.37 billion US dollars) in female patients, respectively. CONCLUSION: This is the first study to estimate medical expenditures for hip fracture using the nationwide health insurance claims database, which represents almost all health insurance claims in Japan. Fragility hip fracture inflicts a considerable health economic burden on society in Japan. |
