BackgroundThe volume‐outcome relationship for organ‐specific transplantation is well‐described; it is unknown if the relative balance of kidney compared with liver volumes within an institution relates to organ‐specific outcomes. We assessed the association between relative balance within a transplant center and outcomes.MethodsNational retrospective analysis of isolated kidney and liver transplants in United States 2005–2014 followed through 2019. Latent class analysis defined transplant center phenotypes. Multivariate Cox models estimated death‐censored graft loss and mortality.ResultsLatent class analysis identified four phenotypes: kidney only (n= 117), kidney dominant (n= 36), mixed/balanced (n= 90), and liver dominant (n= 13). Compared to mixed centers, the risk of kidney graft loss was higher at kidney‐dominant (HR 1.07,p< .001) and liver‐dominant (HR 1.10,p< .001) centers, while kidney‐only (HR 1.06,p= .01) centers had higher mortality. Liver graft loss was not associated with phenotype, but risk of patient death was lower (HR 0.93,p= .02) at liver dominant and higher (HR 1.06,p= .02) at kidney‐dominant centers.ConclusionsA mixed phenotype was associated with improved kidney transplant outcomes, whereas liver transplant outcomes were best at liver‐dominant centers. While these findings need to be verified with center‐level resources, optimization of shared resources could improve patient and organ outcomes.
