Does surgeon volume improve outcomes?
This overview of systematic reviews supports a positive relationship between surgeon volume and outcomes, though specific minimum volume thresholds cannot be recommended.
When taking into account its limitations, this overview can serve as an informational basis for decision makers. Our results seem to support a positive volume-outcome relationship for most procedures/conditions. However, forthcoming reviews should pay more attention to methodology specific to volume-outcome relationship. Due to the lack of information, any numerical recommendations for minimum volume thresholds are not possible. Further research is needed for this issue.
