Abstract

Summary

Little is known about hip fracture expenditure in Japan. Using claims data obtained from a core city near Tokyo, we estimated the mean healthcare expenditure and monthly long-term care expenditure post-hip fracture to be ¥2,600,000 (US$29,500) and ¥113,000 (US$1290), respectively.

Purpose

We aimed to estimate healthcare and long-term care expenditures post-hip fracture in Japan.

Methods

Healthcare insurance claims data for adults aged  75 years were merged with long-term care insurance claims data. We analyzed the data of hip fracture patients who were admitted to non-diagnosis procedure combination/per-diem payment system (DPC/PDPS) hospitals in a core city near Tokyo between April 2012 and September 2013. We estimated healthcare expenditure, namely, the difference between total payments 6 months pre- and 6 months post-hip fracture, and monthly long-term care expenditure for those who did not use long-term care insurance pre-hip fracture, but who commenced long-term care insurance post-hip fracture. We also performed multiple linear regressions to examine the associations of healthcare or long-term care expenditure with various factors.

Results

The estimated mean healthcare (n = 78) and monthly long-term care (n = 42) expenditures post-hip fracture were ¥2,600,000 (US$29,500) and ¥113,000 (US$1290), respectively. In multiple linear regressions, healthcare expenditure was positively associated with longer duration of hospital stay (p = 0.036), and negatively associated with higher Charlson Comorbidity Index scores (p = 0.015). Monthly long-term care expenditure was positively associated with higher care-needs level post-hip fracture (p = 0.022), and usage of institutional care services (p < 0.001).

Conclusions

This is the first study to estimate healthcare and long-term care expenditures post-hip fracture using claims data in Japan. Further studies are needed that include healthcare claims data at both DPC/PDPS and non-DPC/PDPS hospitals to capture the lifelong course of long-term care required post-hip fracture.
