Insights From Refusal Patterns for Deceased Donor Kidney Offers

Area of Science:

• Nephrology
• Transplant Surgery
• Organ Allocation

Background:

• Kidney organ offer utilization varies during allocation.
• Transplant centers can decline offers for single or multiple patients.
• Refusals may indicate patient-specific or organ-specific issues.

Purpose of the Study:

• To investigate kidney offer refusal patterns.
• To differentiate between single and multiple patient refusals.
• To correlate refusal types with organ nonutilization.

Main Methods:

• Analysis of Organ Procurement and Transplantation Network data (2022-2023).
• Categorization of refusals as single (>1 patient) or multiple (>5 patients) per center.
• Examination of refusal codes and nonutilization rates post-cross-clamp.

Main Results:

• Single patient refusals are linked to patient-related reasons and higher utilization.
• Multiple patient refusals are associated with organ-related reasons and increased nonutilization.
• Nonutilization rates were 28% (no refusals), 35% (multiple patient refusal), and 12% (single patient refusal).

Conclusions:

• Early assessment of nonutilization risk is possible by analyzing refusal patterns.
• Understanding refusal dynamics can inform transparent protocols for faster organ placement.
• Distinguishing refusal types aids in optimizing deceased donor kidney allocation.
