Summary
Robotic-assisted total hip arthroplasty (RATHA) is associated with lower 90-day episode-of-care costs compared to manual total hip arthroplasty (mTHA). Savings are driven by reduced post-procedure rehabilitation utilization and expenses.
Area of Science:
- Orthopedic Surgery
- Health Economics
- Medical Technology
Background:
- Total hip arthroplasty (THA) is a common procedure for hip osteoarthritis.
- Resource consumption and cost-effectiveness of different surgical approaches are critical considerations.
Purpose of the Study:
- To compare the 90-day episode-of-care (EOC) resource consumption between robotic-assisted total hip arthroplasty (RATHA) and manual total hip arthroplasty (mTHA).
Main Methods:
- Retrospective analysis of Medicare 100% data for THA procedures.
- Propensity score matching (1:5) to compare 938 RATHA cases with 4,670 mTHA cases.
- Assessment of 90-day EOC cost, index costs, length of stay, and post-index rehabilitation utilization.
Main Results:
- RATHA patients showed significantly lower utilization of post-index inpatient rehabilitation, skilled nursing facilities, and home health agency visits compared to mTHA patients.
- Total 90-day EOC costs for RATHA were $785 lower than for mTHA (p=0.0095).
Conclusions:
- Robotic-assisted total hip arthroplasty (RATHA) is associated with reduced overall 90-day episode-of-care costs compared to manual total hip arthroplasty (mTHA).
- Cost savings in RATHA are primarily attributed to decreased utilization and costs of post-index rehabilitation services.
