The mission of SPLIT’s Advocacy Committee is to advocate on behalf of all children awaiting liver transplantation or after liver transplant. Our objectives are to (1) eliminate preventable waitlist morbidity and mortality through a data-driven approach and (2) collaboratively address actionable patient issues surrounding equitable transplant care access, evaluation, pre- and post-transplant management, and organ allocation policy. Our recent activities include: developing SPLIT responses to UNOS Public Comment proposals on allocation changes that impact children, collaborating with the SPLIT Patient and Family Voice group on social media campaigns to raise awareness and support for issues that affect children with liver transplants, and organizing an upcoming training webinar on addressing racial bias in healthcare. Please come work with us--bring your ideas and your advocate voices!

Committee Update
The Multi-Disciplinary Committee (formerly the Coordinators Committee and Allied Health Professionals Committee) continues to improve the overall timely entry of quality data into the SPLIT Registry, and promote coordinator and other (nonphysician) AHP engagement within SPLIT.


The mission of the Multi-Disciplinary Committee (formerly the Coordinators Committee and Allied Health Professionals Committee (AHP)) is to improve the overall timely entry of quality data into the SPLIT Registry, and promote coordinator and other (nonphysician) AHP engagement within SPLIT. This mission is accomplished by identifying and overseeing educational opportunities, project study implementation, data collection, quality initiatives, and research opportunities. Over the next few years, it is our hope that we can partner with one another to help strengthen this group and the data we collect. This committee is important to get involved in because we are the backbone of the data. We all can learn from one another and continue to make the Multi-Disciplinary Committee successful for years to come.

Quality Improvement and Clinical Care Committee Chair

Bernadette Vitola, MD

Medstar, United States


SPLIT is a central driving force for understanding the standards of present practice and setting the framework for collaborative, and innovative progress in improving the quality and quantity of life for pediatric liver recipients. We have passionate experts from the pediatric liver transplant community who are dedicated to “moving the needle” in quality patient care. This objective is strategically accomplished by targeting challenging areas of liver transplantation that most impact outcomes such as life-threatening complications, benchmarking best practices, implementing the latest healthcare technologies, and facilitating a platform for quality improvement clinical projects that will provide substantive value to the SPLIT centers and the patients/families they serve. Past collaborative projects have disseminated high-performer practices in minimizing major surgical complications, shortening hospital length of stay, and standardizing quality program practices.

Research Committee Chair

Pamela Valentino, MD

Seattle Children's Hospital, United States

The Research Committee identifies, solicits, designs, and reviews research opportunities that leverage the SPLIT Registry and the collaborative SPLIT membership spirit to better the lives of children with liver transplant. The Research Committee is a productive group due to the dynamic and high-energy nature of the diverse committee members. Committee members are experienced Pediatric Hepatologists and Pediatric Liver Surgeons and experts from related domains (i.e Infectious Diseases)
