Pediatric lung transplantation (LTX) remains limited by the scarcity of small donor lungs, particularly in less populated parts of the world. Optimal organ allocation, including the prioritization and ranking of pediatric LTX candidates, and the appropriate matching of pediatric donors to recipients have been crucial elements in improving pediatric LTX outcomes. We aimed to elucidate the various pediatric lung allocation practices worldwide. A global survey of current pediatric solid organ transplantation deceased donation allocation practices was conducted by the International Pediatric Transplant Association (IPTA), and these policies were subsequently analyzed if publicly available, with focus on pediatric lung transplantation. Significant variation was found in lung allocation systems worldwide both in terms of prioritization and distribution for children. Definition of pediatrics varied from <12 years of age to <18 years of age. While several countries performing LTX for young children do not have a formal system to prioritize pediatric candidates, many countries that perform LTX at higher rates do offer prioritization methods for children: including the United States, United Kingdom, France, Italy, Australia, and countries serviced by Eurotransplant. Certain lung allocation practices for pediatrics are highlighted herein, including the newly instituted Composite Allocation Score (CAS) system in the United States, pediatric matching with Eurotransplant, and pediatric prioritization in Spain. The systems highlighted here explicitly aim to provide judicious and high quality LTX care for children.
