1 Liver and Intestinal Organ Transplantation Committee Report to the Board of Directors June 25-26, 2012 Richmond, VA Kim M. Olthoff, MD, Chair David C. Mulligan, MD, Vice-Chair

2 “Share 15 National” “Share 35 Regional” Endorsement of Liver Biopsy Resources (Consent Agenda) Items Submitted for Board Consideration

3 Despite improvements in liver allocation and distribution, waitlist mortality remains high for patients with higher MELD scores Significant disparity exists between OPOs and regions with regard to mean MELD at transplant and waitlist mortality How can we direct livers to most in need? Problem Statement

4 Supporting Data

5 Competing Risk Liver Waiting List Outcome Probabilities at 1-Year Candidates Added 2007-2010 *Status 1A/1B, and candidates with exceptions excluded N=10319 N=15810N=2363

6 Mean Match MELD @ Transplant* Deceased Donor Liver Transplants, 2010 by DSA within Region *Adults only, Exceptions. Some DSAs may overlap

7 Death Rates* @ 365 Days, Candidates Listed for a DD Liver Transplant 1/1/2008-12/31/09 By DSA within Region *Adults only, Calculated using Competing Risks, Exceptions, Initial MELD>=15, Candidates with an Initial Status of 1A/1B Excluded, DSAs with fewer than 10 events excluded

8 Results: Waitlist Mortality – Intent to treat

10 Results: Waitlist Mortality – As treated Status 1A MELD/PELD 35+ 78% Temporarily inactive 22% changed to MELD 53% Temporarily inactive 6.5% changed to 1A/1B 40.5% changed to lower MELD

12 Policy Development

13 Proposal for Regional Sharing (February 2009) Request for Forum (June 2009) RFI and Survey (December 2009) Forum in Atlanta (April 2010) Board directed Committee “to develop recommendations to reduce geographic disparities in waitlist mortality” (June 2010) Concept Paper/Survey (December 2010) Policy Development History I

14 Presentations at AASLD, ASTS Winter Symposium, ATC (2010 and 2011) Public Comment (September - December 2011) Public Webinar (October 2011) Review of Comments (March 2012) Final Committee Vote (May 2012) Policy Development History II

25 Committees in Support: Patient Affairs, Pediatric Transplantation, Transplant Administrators and Transplant Coordinators Societies in Support: AST, ASTS, NATCO Opposition: increased costs/CIT; threshold of 15 being based on old analyses; patients with congenital hepatic fibrosis Public Comments – Share 15

26 Hypothesis: Greater access to organs for sicker candidates will decrease their waiting list mortality, without a demonstrable increase in mortality for other candidates, due to the small number of candidates involved. Data to be reviewed every 6 months post-implementation: Waiting list mortality by MELD score Post-transplant patient and graft survival Percent shared between OPOs Percent shared nationally Plan for Evaluating the Proposal

31 Committees in Support: Patient Affairs, Pediatric Transplantation, Transplant Administrators and Transplant Coordinators Societies in Support: AST, ASTS, NATCO Opposition: increased costs/CIT; potential effect on small programs; inclusion of exceptions and candidates awaiting a combined liver-kidney transplant; and use of a “sharing threshold.” For each option, some comments and regions were in support (e.g., exceptions must be included) while others were in opposition (e.g., exceptions must be excluded). Public Comments – Share 35

32 Sharing threshold Very complicated in concept and would be in practice LSAM modeling – affected only 5% of transplants (ranging from 4.68% to 5.16% across the proposals modeled) CIT SRTR analyses showed that CIT does not correlate well with distance, ranging from 6 hours for very short distances, to 7 hours for distances of 250 miles or more. This may be more related to center practices for transplantation of local versus imported donors. Response to Public Comment - I

44 BIOPSY RESOURCES

45 Organ Availability Committee (OAC) developed a standardized liver biopsy reporting form and accompanying resource document – Committee Dissolved in 2011 Purpose: to improve the accuracy and completeness of the information surgeons need when considering a liver for their patients. Designed for OPOs to make available to their pathologists. Not mandatory, forms; would be provided by OPOs as a resource. Photo resource document: standardized photographs in situ and on the back-bench to assist in decision-making regarding organ suitability by augmenting (but not replacing) clinical judgment and/or biopsy results. Will be helpful when the procuring team is not the transplanting team. Biopsy Resources
