Several countries have adopted policies to concentrate medical procedures in high-volume hospitals. While higher patient volumes might translate to higher quality, we provide evidence for a positive relationship between surgeon supply and hospital revision rates for hip and knee replacement surgery. Hence, hospital performance decreases with higher surgeon supply, and this finding holds conditional on patient volumes.enhealthcare qualitysurgeon supplyvolume-outcome relationshiparticle
