Equity-Efficiency Trade-offs Associated With Alternative Approaches to Deceased Donor Kidney Allocation: A...

Area of Science:

• Nephrology
• Transplantation Medicine
• Health Economics

Background:

• The demand for kidney transplants significantly exceeds the availability of donor organs.
• This disparity necessitates careful consideration of organ allocation strategies to optimize patient outcomes.

Purpose of the Study:

• To quantify the trade-offs between different deceased donor kidney allocation methods.
• To evaluate these methods based on quality-adjusted life years (QALYs), costs, and transplantation access.

Main Methods:

• An individual patient simulation model was developed to compare five kidney allocation approaches.
• The model included the 2006 UK National Kidney Allocation Scheme (NKAS) and a QALY maximization strategy.
• Patient-level data were used to predict survival, utilities, and costs, simulating organ allocation from 2200 donors to 5500 patients.

Main Results:

• The QALY maximization approach yielded 48,045 QALYs at a cost of £681 million for transplant recipients.
• The 2006 NKAS generated 44,040 QALYs at a cost of £625 million for transplant recipients.
• Considering all patients, the 2006 NKAS resulted in higher total QALYs and costs, with an ICER of £110,741/QALY compared to QALY maximization.

Conclusions:

• QALY maximization enhances the efficiency of deceased donor kidney utilization.
• However, this approach reduces transplant access for older individuals and exacerbates health gain inequity.
• Allocation strategies must balance efficiency with equitable access to transplantation.
