Donor evaluation for lung transplantation in Korea

Area of Science:

• Thoracic Surgery
• Transplantation Medicine
• Public Health Policy

Background:

• Lung transplantation is vital for end-stage lung disease, improving survival and function.
• A significant shortage of donor lungs limits lung transplantation (LTx) in Korea.
• Current organ utilization systems require optimization for better outcomes.

Purpose of the Study:

• To assess the number and utilization rates of donor lungs in Korea.
• To identify factors influencing donor lung acceptance and refusal.
• To evaluate the need for an improved organ utilization system for lung transplantation.

Main Methods:

• Retrospective review of donor lung data from the Korean Network for Organ Sharing (2010).
• Analysis of 270 brain-dead donors and their offered lungs.
• Comparison of lung utilization rates with other solid organs.

Main Results:

• Only 18 (6.7%) donor lungs were utilized, significantly lower than other organs.
• Medical ineligibility (poor PaO2, smoking history, age) was the primary reason for refusal.
• Younger donor age (mean 35.7 years) was associated with lung transplantation.
• Lungs not meeting standard criteria were transplanted in 10 cases.

Conclusions:

• The low utilization rate of donor lungs in Korea highlights a critical bottleneck in lung transplantation.
• Barriers to lung donation include medical ineligibility and recipient matching challenges.
• Implementing an efficient organ utilization system is crucial to increase lung transplant rates.
