  7. Evolution of HIV Policy

  8. Precipitous Event • August 1986 • First report of the transmission of HIV by an organ transplanted from a screened donor

  9. Original Policy - May 31, 1988Potential Donor • Test all potential donors with an FDA licensed screening test • Perform a donor history to determine if the potential donor is in a “high risk” group • UNOS would not share organs or tissues that repeatedly tested positive

  10. Original Policy - May 31, 1988Potential Donor (continued) • An exception existed for extra renal organs in extreme medical emergencies, & the transplant surgeons had to notify the recipient or next of kin • Donor consent forms were encouraged to include language stating potential donors would be screened for medical acceptability and these tests could prevent donation

  11. Original Policy - May 31, 1988Potential Recipient • HIV-Ab testing should be a condition for candidacy • An asympotomatic HIV-Ab sero-positive recipient, should not be excluded from transplant candidacy • An HIV-Ab sero-positive with AIDS or AIDS-related complex should be excluded from candidacy

  12. Original Policy - May 31, 1988Additional Issues • Healthcare personnel caring for an AIDS antibody positive patient should be informed • Treatment of AIDS antibody positive patients should not be optional or discretionary • Disclosure of information comply with statutes • UNOS members were requested to adopt an overall policy to address special HIV-related problems

  13. Policy Amended - June 20, 1989 • 4.1.2 UNOS members shall not knowingly participate in the transplantation or sharing of organs from donors who are confirmed reactive for HIV-Ab by an FDA licensed screening test. • 4.2 Testing for HIV-Ab shall be a condition of candidacy… Patients confirmed positive should undergo appropriate counseling.

  14. Policy Amended - June 20, 1989(continued) • 4.2.1 (added) ...but should be advised that they may be at increased risk because of immunosuppressive therapy. The last sentence was deleted. • 4.6 (added) HTLV-I Screening

  15. Next AmendmentsDecember 1, 1991 • Brought to the UNOS Board by the Ad Hoc Committee on Donor Testing at the November 6-7, 1991 meeting • Policy proposal 4.7 was recommended for distribution for public comment

  16. Next AmendmentsDecember 1, 1991 (continued) • 4.7 Transplant Recipient HIV Reporting was implemented December 1, 1991 concurrent with public comment submission • Transplant centers shall immediately notify the procuring OPO and UNOS when recipients test positive for HIV or die from HIV-related causes

  17. Present Policy • At the June 1992 UNOS Board meeting public comment was reviewed and the modified policy accepted

  18. Organ Allocation and Transplant Candidate Criteria

  19. A long, long time ago… B.U. • Allocation & transplant candidate listing criteria were handled by the programs • Allocation progressed to a network-type mechanism • Candidate criteria remained the purview of transplant programs

  20. NOTA - 1984 • Created a task force • April 1986 reported its recommendations

  21. Task Force Recommendations • Establish a single national network for organ sharing • Participants will agree on & adopt uniform policies and standards • Each donated organ is a national resource to be used for public good • Public must participate in the decisions of how this resource can be used to best serve the public interest

  22. Task Force Recommendations (Continued) • Selection of patients for waiting lists and allocation of organs be based on publicly stated medical criteria and be fairly applied • Develop criteria for prioritization through a broadly representative group taking into account both need & probability of success • Selection of patients otherwise equally medically qualified should be based on length of time on the waiting list

  23. Task Force Recommendations (Continued) • Selection of patients for transplant not be subject to favoritism, discrimination on the basis of race, gender, or ability to pay • Organ sharing concepts that are designed to improve the probability of success be implemented in the interests of justice and effective use of organs • Ongoing assessment of mandated organ sharing to identify & rectify imbalances that may reduce access by any group

  24. 1986 - UNOS was awarded a contract to establish the OPTN 1987 - UNOS was awarded a contract to operate the OPTN 1988 - Reauthorization of NOTA OPTN shall establish membership criteria & medical criteria for organ allocation Creation of the OPTN

  25. Allocation policies historically balanced justice and medical utility Candidate listing criteria continued largely to be a program-specific function OPTN Policy Development

  26. A Bump in the Road • April 2, 1998 • Department of Health and Human Services (HHS) • Organ Procurement and Transplantation Network; Final Rule • 60-day public comment

  27. Public Discussion Ensued • Resulting in a moratorium in 1999 • Commissioned an IOM study

  28. Results of the OPTN Final Rule The OPTN will develop: • Criteria aimed at allocating organs first to those in the highest medical urgency status, with reduced reliance on geographical factors • This should reduce disparities in waiting times

  29. Results of the OPTN Final Rule(Continued) • Criteria to be followed in deciding when to place patients on the waiting list • Medically objective criteria to be used by all transplant centers

  30. Results of the OPTN Final Rule(Continued) • Criteria for determining the status of patients who are listed • Medically objective, uniform criteria would help ensure a “level playing field” in selecting patients & determining greatest medical need

  31. Organ Specific Criteria • Minimum listing criteria were already being developed • Pediatric and adult liver criteria are policy • Heart, Lung & Heart-Lung criteria are presently guidelines

  32. Determining Highest Medical Urgency Status • Public forums were held • Liver Disease Severity Scale Committee • Liver Committee • Public comment X 2 • Regional Meetings

  33. Result: MELD System • Model for End Stage Liver Disease • Based on short term risk of death without a liver transplant (3 months) • Formula that is calculated based on medically objective, uniform criteria

  34. Suggested Elements of the Liver Disease Severity Score • Bilirubin cholestatic, INR , Albumin, & Creatinine • Hepatocellular Carcinoma • Spontaneous Bacterial Peritonitis • TIPS (contraindications were noted) • Intubated • Chronic bleeding ( 3 days over 7 days)

  35. Additional Suggestions • The scale be tested & refined • Other predictors of mortality (i.e., cholangitis, hepatopulmonary syndrome, and non-liver comorbidities) eventually be included in the scale to improve its predictive accuracy • There should be an inclusive national forum held

  36. Questions, Comments & Concerns

  37. OPTN/UNOS Ethics Committee • Supports the basic concept demonstrated by the MELD ideology • Believes identifying patients at greatest risk of dying is well founded in the ethical principle of justice • However, the use of organs for critically ill patients for transplant may not demonstrate the ethical principle of medical utility

  38. OPTN/UNOS Ethics Committee (Continued) • Recommends continued evaluation in the realm of medical utility • Recommends periodic reviews of the outcomes to ensure that no specific group is disadvantaged (i.e., the use of serum creatine vs. creatine clearance as an element of the MELD system may disadvantage women)

  39. Next Steps • Liver Disease Severity Scale Committee met July 25, 2001 • Liver Committee met July 26, 2001 • HIV+ candidate concerns were on the agenda • Modifications are still occurring

  40. Concluding Remarks • Policy-making regarding organ transplantation has never suffered from inertia • Use the existing mechanisms to allow your voice to be heard • Offer to present to the appropriate committees
