Accurate assessment of the impact of donor quality on liver transplant (LT) costs has been limited by the lack of a large, multicenter study of detailed clinical and economic data. A novel, retrospective database linking information from the University HealthSystem Consortium and the Organ Procurement and Transplantation Network registry was analyzed using multivariate regression to determine the relationship between donor quality (assessed through the Donor Risk Index [DRI]), recipient illness severity, and total inpatient costs (transplant and all readmissions) for 1 year following LT. Cost data were available for 9059 LT recipients. Increasing MELD score, higher DRI, simultaneous liver-kidney transplant, female sex, and prior liver transplant were associated with increasing cost of LT (P < 0.05). MELD and DRI interact to synergistically increase the cost of LT (P < 0.05). Donors in the highest DRI quartile added close to $12,000 to the cost of transplantation and nearly $22,000 to posttransplant costs in comparison to the lowest risk donors. Among the individual components of the DRI, donation after cardiac death (increased costs by $20,769 versus brain dead donors) had the greatest impact on transplant costs. Overall, 1-year costs were increased in older donors, minority donors, nationally shared organs, and those with cold ischemic times of 7-13 hours (P < 0.05 for all). In conclusion, donor quality, as measured by the DRI, is an independent predictor of LT costs in the perioperative and postoperative periods. Centers in highly competitive regions that perform transplantation on higher MELD patients with high DRI livers may be particularly affected by the synergistic impact of these factors., (Copyright © 2011 American Association for the Study of Liver Diseases.)

We examined the relationship between the total cost incurred by liver transplantation (LT) recipients and their Model for End-Stage Liver Disease (MELD) score at the time of transplant. We used a novel database linking billing claims from a large private payer with the Organ Procurement and Transplantation Network registry. Included were adults who underwent LT from March 2002 through August 2007 (n = 990). Claims within the year preceding and following transplantation were analyzed according to the recipient's calculated MELD score. Cost was the primary endpoint and was assessed by the length of stay and charges. Transplant admission charges represented approximately 50% of the total cost of LT. MELD was a significant cost driver for pretransplant, transplant, and total charges. A MELD score of 28 to 40 was associated with additional charges of $349,213 (P < 0.05) in comparison with a score of 15 to 20. Pretransplant and transplant admission charges were higher by $152,819 (P < 0.05) and $64,286 (P < 0.05), respectively, in this higher MELD group. No differences by MELD score were found for posttransplant charges. Those in the highest MELD group also experienced longer hospital stays both in the pretransplant period and at the time of LT but did not have higher rates of re-admissions. In conclusion, high-MELD patients incur significantly higher costs prior to and at the time of LT. Following LT, the MELD score is not a significant predictor of cost or re-admission., (Copyright 2009 AASLD)
