Regional Differences in the Utilization of Low-Value Orthopedic Services

Overview

This study evaluates geographic variation in the utilization of five low-value orthopedic services among Medicare-eligible veterans. It finds substantial regional differences in service rates, with weak correlations among the services.

Background

Low-value services (LVSs) contribute significantly to unnecessary healthcare expenditures, particularly in orthopedic care, which is a major area of Medicare spending. Understanding regional variations in LVS utilization is crucial for developing effective strategies to reduce wasteful practices. This study addresses the gap in knowledge regarding the clustering of LVSs across different regions.

Data Highlights

Key Findings

• Substantial geographic variation in the prevalence of orthopedic LVSs among Medicare-enrolled veterans.
• Weighted mean rates for services ranged from 0.3 for knee arthroscopies to 44.6 for back imaging.
• Spinal injections exhibited the greatest variation, with rates in high-use regions being 3.5 times those in low-use regions.
• Weak correlations were found between the use of different LVSs, with r values ranging from -0.21 to 0.20.
• Only 15.6% of HRRs exceeding the 75th percentile for spinal fusion also exceeded the 75th percentile for back imaging.

Clinical Implications

The findings indicate that healthcare providers and policymakers should consider regional differences in LVS utilization when designing interventions aimed at reducing unnecessary orthopedic procedures. Understanding these patterns may help in tailoring strategies to specific regions rather than applying a one-size-fits-all approach.

Conclusion

This study highlights significant geographic variation in the use of low-value orthopedic services among Medicare-eligible veterans, with limited clustering across different services.
