Summary
Higher surgical volumes for total hip arthroplasty (THA) correlate with better patient outcomes, including reduced dislocation rates. Surgeon volume showed a stronger association than hospital volume in this review.
Area of Science:
- Orthopedic Surgery
- Health Services Research
- Patient Outcomes
Background:
- The practice-makes-perfect effect suggests increased procedure volume improves outcomes.
- Outcomes-based research is increasingly examining surgical volume's impact.
- Total hip arthroplasty (THA) outcomes are a focus of this research.
Purpose of the Study:
- To review existing literature on surgeon and hospital volume effects on THA outcomes.
- To specifically analyze the impact of volume on THA dislocation rates.
Main Methods:
- Systematic review of published literature.
- Analysis of studies examining volume-outcome relationships in THA.
- Focus on dislocation as a key outcome measure.
Main Results:
- A significant positive association exists between higher surgical volumes and improved THA outcomes.
- Increasing surgical volume is linked to lower rates of dislocation after THA.
- The correlation between volume and outcomes is more robust for surgeon volume than hospital volume.
Conclusions:
- Higher surgeon and hospital volumes are associated with better outcomes in total hip arthroplasty.
- Increased surgical experience, particularly at the surgeon level, appears to reduce THA dislocation risk.
- Findings have implications for healthcare consumers, providers, and policymakers.
