Additional Study Information: The social determinants of health have a large impact on health. We have previously demonstrated that an index of neighborhood socioeconomic deprivation was associated with an increased risk of medication non-adherence in children after liver transplant and an increased risk of graft failure and death in children after transplant. The present proposal seeks to survey caregivers of children undergoing liver transplantation as well as conduct in-depth, qualitative interviews. The survey will assess comprehensively for the social determinants of health (e.g. material economic hardship, health literacy, social connectedness, primary care quality, etc). This survey data will be linked to an existing prospective cohort study (The Society for Pediatric Liver Transplant registry) to assess the impact of social risk on outcomes after transplant. The qualitative aim of this proposal is to identify barriers and facilitators that socioeconomically deprived children/families have to obtain the ideal outcome and identify health system opportunities to integrate social needs and medical care.
