The transplant ecosystem: Investing in comprehensive care for pediatric liver failure
Liver failure is a life-threatening condition that can lead to multi-organ dysfunction, substantial morbidity and death. In the absence of therapies that reverse severe liver injury, supportive care is provided as a bridge to either liver recovery, given the organ’s remarkable capacity for regeneration, or liver transplantation.
Children with liver failure present a distinct clinical challenge given their size, evolving developmental needs and the limited availability of appropriately sized donor organs. In the United States, children account for about 500 of the 10,000 liver transplants performed annually. In this population, rarity only raises the stakes – a successful pediatric transplant can mean decades of life ahead.
Accordingly, advocacy in pediatric transplantation largely focuses on improving access to organs and surgical approaches. In recent decades, amendments to organ allocation policies have strived to increase pediatric priority by accounting for factors like organ size, medical urgency and geographic location. Surgical innovations, like split-liver transplantation and normothermic machine perfusion, also are expanding the pool of viable organs.
Still, gaps remain. Infants continue to experience the highest waitlist mortality, and about 5-10% of children are deemed too sick to transplant every year. These outcomes highlight an often-overlooked aspect of the transplant ecosystem: the infrastructure and expertise needed to care for a fragile population before, during and after transplantation.
The intensive care unit (ICU) is central to this continuum. Children with liver failure require intensive management of multiple organ systems to survive the acute illness and, once stabilized, must be maintained in the uncertain window of awaiting an organ. During this time, ICU physicians navigate complex decisions about interventions like dialysis and extracorporeal liver support systems, balancing benefit against the difficulties of caring for children, such as technical limitations due to size, and complications of prolonged, critical illness like infection and delirium. 
When a donor organ becomes available, the decision to proceed must consider the child’s organ function, degree of physiologic instability and likelihood of tolerating surgery – ICU expertise is vital to these time-sensitive decisions. After transplant, the goal of ICU care is to facilitate recovery and protect the new liver while minimizing complications. Throughout this emotionally complex journey, the child and their family must remain the focus of care. Centralized, multidisciplinary care is therefore essential to complement the national improvements in organ allocation and transplant surgery.
The Liver Intensive Care Unit at Texas Children’s Hospital, established in 2014, exemplifies advocacy at the bedside. By bringing dedicated liver ICU physicians together with experts from surgery, hepatology and multiple pediatric subspecialties, this model supports the resource-intensive care needed to achieve strong outcomes. Today, Texas Children’s Hospital’s experience as a leading transplant center shows how highly coordinated clinical care can expand what is possible for even the youngest, sickest patients.
Pediatric centers with subspecialty expertise are uniquely positioned to advance care and innovation in a healthcare landscape that remains largely adult-centric. As five-year patient and organ survival rates exceed 90%, the goals of pediatric liver transplant should extend beyond survival. Realizing the full potential of donated organs requires continued investment in the infrastructure, resources and research needed to care for children across all aspects of the transplant ecosystem.
