Centralizing vascular surgery services may improve patient outcomes. Higher hospital and surgeon volumes correlate with better results in arterial surgery, supporting a move towards specialized care centers.
Area of Science:
- Vascular Surgery
- Health Services Research
Background:
- Vascular surgical procedures are often performed in hospitals with low individual unit workloads.
- Evidence suggests a link between higher hospital/surgeon volume and improved arterial surgery outcomes.
Purpose of the Study:
- To systematically review evidence on volume-outcome relationships in vascular surgery.
- To examine the rationale for centralizing vascular surgical services.
Main Methods:
- Systematic review of existing literature.
- Analysis of data from multiple healthcare systems.
Main Results:
- Positive volume-outcome relationships identified in vascular surgery.
- Centralization could increase procedural volume and enhance patient outcomes.
Conclusions:
- Centralizing vascular surgical services is supported by evidence.
- Increased volume in specialized centers may lead to better outcomes for complex aortic and carotid procedures.
