Models of OPO performance from the Scientific Registry of Transplant Recipients make it possible to study this question in a data\u2010driven manner. We investigated whether each OPO's net liver import was correlated with 2 performance metrics [observed to expected (O:E) liver yield and liver donor conversion ratio] as well as 2 alternative explanations [eligible deaths and incident listings above a Model for End\u2010Stage Liver Disease (MELD) score of 15]. We found no evidence to support the hypothesis that the allocation system transfers livers from better performing OPOs to centers with poorer performing OPOs. Also, having fewer eligible deaths was not associated with a net import. However, having more incident listings was strongly correlated with the net import, both before and after Share 35. Most importantly, the magnitude of the variation in OPO performance was much lower than the variation in demand: although the poorest performing OPOs differed from the best ones by less than 2\u2010fold in the O:E liver yield, incident listings above a MELD score of 15 varied nearly 14\u2010fold. Although it is imperative that all OPOs achieve the best possible results, the flow of livers is not explained by OPO performance metrics, and instead, it appears to be strongly related to differences in demand. <jats:italic toggle=\"yes\">Liver Transpl 21:293\u2013299, 2015<\/jats:italic>. \u00a9 2015 AASLD.<\/jats:p>","DOI":"10.1002\/lt.24074","type":"journal-article","created":{"date-parts":[[2014,12,31]],"date-time":"2014-12-31T06:13:10Z","timestamp":1420006390000},"page":"293-299","source":"Crossref","is-referenced-by-count":21,"title":["Liver sharing and organ procurement organization performance"],"prefix":"10.1097","volume":"21","author":[{"given":"Sommer E.","family":"Gentry","sequence":"first","affiliation":[{"name":"Department of Surgery,Johns Hopkins University School of Medicine,Baltimore,MD"},{"name":"Department of Mathematics,US Naval Academy,Baltimore,MD"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric K.
