Statistical Bulletin (Metropolitan Life Insurance Company : 1984)
|April 1, 1996
Summary
Total knee replacement (TKR) costs vary significantly by region, with New York and California showing the highest average charges. Physician fees constitute about one-fourth of the total surgery costs.
Area of Science:
- Orthopedics
- Health Economics
- Medical Economics
Background:
- Total knee replacements (TKRs) have seen a significant increase in utilization since 1989.
- Rising healthcare costs are a concern, particularly for major surgical procedures like TKRs.
Purpose of the Study:
- To analyze the geographic variations in total charges for total knee replacements (TKRs).
- To examine the components of TKR costs, including hospital and physician fees, and their relation to hospital stay duration.
Main Methods:
- Analysis of 1994 insurance claims data for total knee replacements (TKRs).
- Comparison of average total charges, physician fees, hospital stay duration, and per diem rates across different US states.
Main Results:
- The national average charge for a TKR in 1994 was $28,340, with significant state-level variations.
- New York and California reported the highest average total charges (27.1% above average), while Ohio had the lowest (19.3% below average).
- Average physician fees were $7,150, representing approximately one-fourth of total costs. Hospital stays averaged 6.7 days, with New York having the longest (over 11.5 days) and Arizona the shortest (4.6 days). Per diem charges showed an inverse relationship with hospital stay duration.
Conclusions:
- Geographic location substantially impacts the cost of total knee replacement surgery.
- Understanding cost variations and components is crucial for healthcare cost management and patient financial planning.
