The social determinants of health, defined as the conditions in which we live, learn, work, and play, undoubtedly impact health outcomes. Social adversity in childhood perpetuates over the life course and has consequences extending into adulthood. This link between social adversity and adverse outcomes extends to children undergoing liver transplant, with children from socioeconomically deprived neighborhoods experiencing a greater burden of morbidity and mortality after transplant. Yet, we lack an in-depth understanding of how to address social adversity for these children. Herein, we lay out a strategy to develop and test interventions to address social adversity for children undergoing liver transplant. To do so, we believe that more granular data on how specific social risk factors (e.g., food insecurity) impact outcomes for children after liver transplant are needed. This will provide the liver transplant community with knowledge on the most pressing problems. Then, using the National Academies of Sciences, Engineering, and Medicine's framework for integrating social needs into medical care, the health system can start to develop and test health system interventions. We believe that attending to our patients' social adversity will realize improved outcomes for children undergoing liver transplant. (Hepatology 2021;74:2824-2830).C linical scenario: Luis (age 5 years) received a transplant 2 years ago for biliary atresia and is in the liver clinic for his annual appointment. When the hepatologist opens the electronic health record, she notices that his medication level variability index (MLVI) is high, suggesting poor medication adherence. She counsels the patient/family on the importance of taking his medications and advises them to set up an app on their smartphone. What she does not realize, however, is that the family has been receiving eviction notices from their landlord. They have been so preoccupied with the threat of eviction that they have overlooked aspects of their child's liver transplant care. This physician, without the proper tools at her disposal, missed an important root cause of this child's poor adherence and, in turn, missed an opportunity to improve this child's adherence. Yet, a brief screening tool in the clinic waiting room may have allowed this clinician to identify and intervene on Luis' unstable housing.The social determinants of health, defined as the conditions in which we live, learn, work, and play, strongly influence health outcomes (1) ; health and disease are inextricably linked to factors extending beyond the walls of the hospital or clinic. (2) The term "social determinants of health" reflects many intersecting domains, including structural issues like affordable housing, school quality, and neighborhood safety that lead to downstream consequences such as poverty. These environmental influences are particularly salient for children and accumulate over the life course. (1) For example, exposure to violence in childhood leads to a lower intelligence quotient later in life, (3...
