Statistical Bulletin (Metropolitan Life Insurance Company : 1984)
|October 1, 1996
Summary
Total hip replacement (THA) is a successful surgery for hip osteoarthritis. In 1994, over 150,000 THAs and revisions were performed, with significant regional cost variations and average hospital stays of around 6 days.
Area of Science:
- Orthopedic Surgery
- Health Economics
- Medical Device Market Analysis
Background:
- Total hip arthroplasty (THA) is a highly successful surgical intervention for severe hip osteoarthritis.
- In 1994, the United States saw approximately 124,000 primary THAs and 28,000 THA revisions.
- Significant financial and resource utilization disparities exist in THA procedures.
Purpose of the Study:
- To analyze the economic and utilization landscape of total hip arthroplasty (THA) in U.S. hospitals.
- To identify regional and state-level variations in THA costs and patient length of stay.
- To provide insights into the cost components of primary THA versus revision procedures.
Main Methods:
- Retrospective analysis of national hospital discharge data for 1994.
- Calculation of average hospital and physician charges for primary THA and THA revisions.
- Comparison of charges and lengths of stay across different U.S. geographic regions and states.
Main Results:
- Average total charges for a primary THA in 1995 were $23,260, with hospital charges comprising 72%.
- Regional cost variations were substantial, with charges ranging from $19,930 to $25,500.
- THA revision surgeries incurred higher average total charges ($27,760) and longer hospital stays (6.6 days) compared to primary THAs (5.9 days).
Conclusions:
- Total hip arthroplasty (THA) procedures exhibit considerable economic variability across U.S. regions.
- Understanding these cost and utilization patterns is crucial for healthcare management and policy.
- THA revision surgeries represent a significant cost driver compared to primary procedures.
