Moving kidney allocation forward: the ASTS perspective.

Area of Science:

• Nephrology
• Transplant Surgery
• Health Policy

Background:

• The United Network for Organ Sharing (UNOS) proposed a kidney allocation policy revision in 2008.
• The proposed policy aimed to integrate dialysis duration, donor factors, and estimated life years from transplant (LYFT) into a ranking score for candidates.
• Concerns were raised regarding the primary reliance on LYFT and the adequacy of the underlying long-term survival models.

Purpose of the Study:

• To evaluate the proposed UNOS kidney allocation policy revision.
• To assess the suitability of incorporating Life Years From Transplant (LYFT) as a primary ranking criterion.
• To propose alternative policy solutions addressing identified shortcomings.

Main Methods:

• Analysis of the proposed kidney allocation policy, focusing on the integration of dialysis time, donor characteristics, and LYFT.
• Critical review of the long-term survival models used for LYFT calculation, assessing patient preference incorporation and predictive accuracy.
• Formulation of alternative policy recommendations.

Main Results:

• The proposed policy faced significant opposition due to its complexity and the lack of consensus on using LYFT as the primary ranking metric.
• Concerns were identified regarding the predictive accuracy of survival models and the absence of patient preference considerations.
• The perceived marginal increase in overall utility did not outweigh the compromise in individual justice.

Conclusions:

• The American Society of Transplant Surgeons did not endorse the proposed kidney allocation policy.
• The policy was deemed overly complex, and the use of LYFT as a central ranking factor was questioned.
• Alternative policy options were suggested to improve kidney allocation while upholding principles of individual justice.
