Pediatric liver transplant outcomes exhibit disparities, necessitating identification of modifiable risk factors to develop targeted interventions. We characterized associations between household material economic hardship (e.g., financial barriers to housing or food) and pediatric liver transplant outcomes. We recruited pediatric liver transplant recipients <18 years at the time of transplant across 8 U.S. centers. Our primary exposure was >/=1 household material economic hardship (i.e., food insecurity, housing instability, transportation challenges, or utility concerns), measured using the Accountable Healthcare Communities screening tool. Outcomes included 90-day and 1-year (1) total inpatient-bed days, and (2) episodes of T-cell mediated rejection (TCMR). Of the 77 participants (36% female), 34% reported household material economic hardship. Such hardship was associated with increased total inpatient bed-days within 90 days (ratio estimate: 1.45, 95%CI: 1.08, 1.96); the association persisted after adjusting for health literacy, insurance, and transplant center (ratio estimate: 1.37, 95%CI: 1.02, 1.84). Household material economic hardship was associated with total inpatient bed-days within 1-year post-transplant (ratio estimate: 3.2, 95%CI: 1.1, 10.1); associations diminished in multivariable analyses (ratio estimate: 2.2, 95%CI: 0.7, 6.9). Household material economic hardship was associated with increased risk of TCMR within 1 year of transplant (RR: 2.1, 95%CI: 1.1, 4.2); the association diminished in propensity-score matched analyses (RR: 1.4, 95%CI: 0.9, 2.3). Our findings highlight the adverse influence of household material economic hardship on pediatric liver transplant outcomes within the first year. Targeted social risk assistance and adjustment strategies offer actionable avenues to mitigate these challenges and enhance outcomes in pediatric liver transplant recipients.

Health care transition (HCT) is a vulnerable period that continues into adulthood, even after the transfer of care. Given the growing population of pediatric liver transplant recipients reaching young adulthood, the need for a standardized and multidisciplinary approach to transition that spans from pediatric to adult care is becoming more imperative. In this article, we review the unique challenges and barriers to successful HCT that adolescent and young adults (AYAs) who have undergone liver transplant face, highlight the gap in transition care in the adult setting, and present the Six Core Elements of Health Care Transition TM as a framework that can be used by adult providers to incorporate AYAs systematically and collaboratively into adult practice. Multidisciplinary HCT programs should be the standard of care for all AYAs with liver transplant, and while implementation is a necessary first step, ongoing efforts to increase awareness, funding, and research on HCTs into adulthood are needed.

INTRODUCTION/BACKGROUND:The LT evaluation and waitlisting process is subject to variations in care that can impede quality. The American Association for the Study of Liver Diseases (AASLD) Practice Metrics Committee (PMC) developed quality measures and patient-reported experience measures (PREMs) along the continuum of pre-LT care to reduce care variation and guide patient-centered care. METHODS:Following a systematic literature review, candidate pre-LT measures were grouped into four phases of care: referral, evaluation and waitlisting, waitlist management, and organ acceptance. A modified Delphi panel with content expertise in hepatology, transplant surgery, psychiatry, transplant infectious disease, palliative care and social work selected the final set. Candidate PREMs spanned domains of cognitive health, emotional health, social well-being, and understanding the LT process. RESULTS:Of the 71 candidate measures, 41 were selected: 9 for referral; 20 for evaluation and waitlisting; 7 for waitlist management; and 5 for organ acceptance. A total of 14 were related to structure, 17 were process measures and 10 were outcome measures that focused on elements not typically measured in routine care. Among the PREMs, LT candidates rated items from understanding the LT process domain as the most important. CONCLUSION/CONCLUSIONS:The proposed pre-LT measures provide a framework for quality improvement and care standardization among LT candidates. Select measures apply to various stakeholders such as referring practitioners in the community and LT centers. Clinically meaningful measures that are distinct from those used for regulatory transplant reporting may facilitate local QI initiatives to improve access and quality of care.

Health care transition (HCT) is the process of changing from a pediatric to an adult model of care. Young adult pediatric recipients of liver transplant transferring from pediatric to adult health care services are highly vulnerable and subject to poor long-term outcomes. Barriers to successful transition are multifaceted. A comprehensive HCT program should be initiated early in pediatrics and continued throughout young adulthood, even after transfer of care has been completed. It is critical that pediatric and adult liver transplant providers establish a partnership to optimize care for these patients. Adult providers must recognize the importance of HCT and the need to continue the transition process following transfer. While this continued focus on HCT is essential, current literature has primarily offered guidance for pediatric providers. This position paper outlines a framework with a sample set of tools for the implementation of a standardized, multidisciplinary approach to HCT for adult transplant providers utilizing "The Six Core Elements of HCT." To implement more effective strategies and work to improve long-term outcomes for young adult patients undergoing liver transplant, HCT must be mandated as a routine part of posttransplant care. Increased advocacy efforts with the additional backing and support of governing organizations are required to help facilitate these practices.

BACKGROUND:An increasing number of pediatric solid organ transplant (SOT) recipients are surviving into adolescence and young adulthood. The transition from pediatric to adult-oriented care occurs during a unique and vulnerable period. METHODS:Presented here is a structured approach to healthcare transition (HCT) for adolescent and young adult SOT recipients aimed at optimizing independence in order to assist young patients with adherence, self-management, and improved quality of life. RESULTS:Close attention must be paid to neurocognitive development, mental well-being, and social determinants of health. CONCLUSIONS:These efforts require a multidisciplinary team approach as well as collaboration between pediatric and adult providers in order to achieve these goals and patient longevity.

Disparities exist in pediatric liver transplant (LT). We characterized barriers and facilitators to providing transplant and social care within pediatric LT clinics. This was a multicenter qualitative study. We oversampled caregivers reporting household financial strain, material economic hardship, or demonstrating poor health literacy. We also enrolled transplant team members. We conducted semistructured interviews with participants. Caregiver interviews focused on challenges addressing transplant and household needs. Transplant provider interviews focused on barriers and facilitators to providing social care within transplant teams. Interviews were recorded, transcribed, and coded according to the Capability, Opportunity, Motivation-Behavior model. We interviewed 27 caregivers and 27 transplant team members. Fifty-two percent of caregivers reported a household income <$60,000, and 62% reported financial resource strain. Caregivers reported experiencing (1) high financial burdens after LT, (2) added caregiving labor that compounds the financial burden, (3) dependency on their social network's generosity for financial and logistical support, and (4) additional support being limited to the perioperative period. Transplant providers reported (1) relying on the pretransplant psychosocial assessment for identifying social risks, (2) discomfort initiating social risk discussions in the post-transplant period, (3) reliance on social workers to address new social risks, and (4) social workers feeling overburdened by quantity and quality of the social work referrals. We identified barriers to providing effective social care in pediatric LT, primarily a lack of comfort in assessing and addressing new social risks in the post-transplant period. Addressing these barriers should enhance social care delivery and improve outcomes for these children.

BACKGROUND:Adolescent and young adult (AYA) solid organ transplant (SOT) recipients experience increased rates of rejection and graft loss surrounding the time of health care transition, in part due to poor medication adherence. This study aims to examine the impact of a once-daily formulation of tacrolimus, LCP-tacrolimus (LCPT), on medication adherence for AYA SOT patients. METHODS:A retrospective descriptive analysis was performed for all patients who underwent SOT and were prescribed LCPT after the age of 12 at our single-center pediatric hospital. Medication adherence was assessed via provider documentation and the medication level variability index (MLVI). RESULTS:Twenty-nine patients were prescribed LCPT as part of their immunosuppression regimen. Twenty patients were converted to LCPT from immediate-acting (IR) tacrolimus; six patients were initiated immediately following transplant, and three patients were unable to receive LCPT due to insurance denial. There was a numeric improvement in medication adherence for converted patients when measured by provider assessment (45.0% vs. 68.4%, p = .140) and MLVI (40.0% vs. 71.4%, p = .276), though these did not reach statistical significance. There were no differences in episodes of rejection or adverse effects. LCPT prescription was not associated with decreased medication burden, and two patients transitioned back to IR tacrolimus due to increased cost. CONCLUSIONS:LCPT use did not significantly improve patient adherence; however, it resulted in numerically higher perceived and measured adherence rates. LCPT appears to be safe and effective in the management of SOT recipients; however, it may not affect pill burden and may result in a higher financial burden. Use may be considered for a select group of AYA SOT recipients.

Racial, ethnic, and socioeconomic disparities exist in the prevalence and natural history of chronic liver disease, access to care, and clinical outcomes. Solutions to improve health equity range widely, from digital health tools to policy changes. The current review outlines the disparities along the chronic liver disease health care continuum from screening and diagnosis to the management of cirrhosis and considerations of pre-liver and post-liver transplantation. Using a health equity research and implementation science framework, we offer pragmatic strategies to address barriers to implementing high-quality equitable care for patients with chronic liver disease.

Pediatric liver transplant recipients have increased rates of morbidity and mortality following transfer to adult health care providers. The role of health literacy (HL) has not been adequately assessed in this population and may be an unrecognized barrier to successful health care transition. We sought to determine the impact of HL for patients and their caregivers on measures of transition readiness (TR), adherence, health-related quality of life, and medical outcomes following pediatric liver transplant. This is a single-center study of pediatric liver transplant recipients transplanted between the ages of 12 and 26 from October 2016 through August 2020. Patients and caregivers completed 4 surveys to evaluate TR, health-related quality of life, and HL. Clinical outcomes were stratified based on the presence or absence of adequate HL. Limited HL was identified in 57.0% of recipients and 47.4% of caregivers. Patients with limited HL were more likely to be younger in age ( p = 0.004), Hispanic ( p = 0.003), and less likely to have obtained a high school diploma or equivalent ( p < 0.001). Patients with adequate HL demonstrated significantly higher levels of TR ( p < 0.001). Patient HL did not impact health-related quality of life, adherence, or medical outcomes. Caregiver HL did not impact patient outcomes or adherence, though higher levels of caregiver education were associated with adequate patient HL ( p = 0.049). This study demonstrates that limited HL is associated with decreased measures of TR. Inadequate HL may be an unrecognized barrier to a successful health care transition. Regular assessment of HL may provide an opportunity for intervention prior to transfer of care. Future studies should investigate the impact of these interventions on long-term medical outcomes.
