Abstract
Summary
This study aimed to compare fracture incidence in the elderly pre- and post-revision of bone density scan reimbursement guidelines, which changed in 2007. Fracture incidence by age group was calculated using population-specific data. Guideline changes did not appear to reduce fracture incidence in the study region located in south-eastern Australia.
Purpose
In 2007, Medicare Australia revised reimbursement guidelines whereby individuals aged 70 years and over received reduced out-of-pocket expenses for dual energy X-ray absorptiometry (DXA) scans. The current study aims to determine whether fracture incidence in the elderly has changed since the revision of reimbursement guidelines.
Method
Keyword searches of the two major radiological centres servicing the Barwon Statistical Division (BSD) were used to identify incident fractures for residents aged 75 years and over for 2006 and 2012. Pathological fractures were excluded. Fracture incidence by age strata (75–79 years, 80–84 years and 85+ years) were calculated using population-specific data from the Australian Bureau of Statistics (2006 and 2012). Standardised fracture ratios were calculated for men and women.
Results
In total, 996 fracture events were identified for BSD residents during 2006 and 1260 identified in 2012. The standardised fracture ratios between 2006 and 2012 were 1.12 (95%CI 1.11, 1.25) for men and 1.08 (95%CI 1.11, 1.16) for women.
Conclusion
The change in reimbursement guidelines appears to have had little impact on reducing fracture incidence during this time frame for elderly men and women, in fact, fracture rates increased. Future research should investigate osteoporosis management following DXA over a longer time frame.
