Adherence, Medical Outcomes, and Health Care Costs in Adolescents/Young Adults Following Pediatric Liver Transplantation

The use of once-daily LCP-Tacrolimus with adolescent and young adult solid organ transplant recipients

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.

Pediatric liver transplant recipients are not just young adults: The importance of a structured health care transition program in adult transplant centers

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 TransitionTM 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.

The impact of health literacy on adolescent and young adult pediatric liver transplant recipients

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.

Changes over time in self-efficacy and the allocation of responsibility for health management tasks in pediatric liver transplant recipients: Targets to improve the transition process

BACKGROUND

The process of transition to adult-based care encompasses a critical period in the life of an adolescent and young adult living with a chronic illness and one that comes with an increase in the risk of poor health outcomes. As yet, there is a dearth of empirical data to help optimize this process to ensure the best long-term outcome.

METHODS

This study used a principal components analysis to determine specific constructs measured by a revised version of the transition readiness survey used in our clinic. We investigated changes in these constructs over time. We further investigated the relationship between the change in these constructs over time spent in a focused transition program with adherence.

RESULTS

The primary component underlying our transition readiness survey for patients and parents represented self-efficacy. Time spent in the transition program was an independent predictor of change in self-efficacy (rho 0.299, p = .015); however, the magnitude of that change had no relationship to adherence. Change in parent-proxy self-efficacy was found to have a statistically significant relationship with tacrolimus standard deviation (rho -0.301, p = .026). There was disagreement identified between patient and parent responses on the survey. Neither change in patient nor parent reports of self-efficacy was found to have a relationship with post-transfer adherence.

CONCLUSIONS

This study reaches the novel conclusion that self-efficacy and parent-proxy self-efficacy are dynamic concepts that change over time spent in a focused transition program. The patient-parent disagreement and the relationship between parent-proxy self-efficacy and adherence stress the importance of involving parents/guardians in the transition process as well.

Current approach to health care transition and integration into adult care for pediatric liver transplant recipients: A call for partnership

Despite the increased risk of non-adherence, allograft rejection, and mortality following transfer from pediatric to adult care in liver transplantation (LT), there is no standardized approach to health care transition (HCT). Two electronic national surveys were developed and distributed to members of the Society for Pediatric Liver Transplantation and all adult LT programs in the United States to examine current HCT practices. Responses were received from 40 pediatric and 79 adult centers. Pediatric centers were more likely to focus on HCT noting the presence of a transition/transfer policy (60.2% vs. 39.2%), transition clinic (51.6% vs. 16.5%), and the routine use of transition readiness assessment tools (54.8% vs. 10.2%). Perceived barriers to HCT were similar among pediatric and adult respondents and included patient willingness to transfer and participate in care, failure to show for appointments, and lack of sufficient time and staffing. These results highlight the need for an increased awareness of HCT at both pediatric and adult LT centers. The path to improvement requires a partnership between pediatric and adult providers. Recognizing the importance of a comprehensive HCT program initiated in pediatrics and continued throughout young adulthood with ongoing support by the adult team is essential.

Optimizing transition from pediatric to adult care in short bowel syndrome and intestinal failure

As the majority of children with short bowel syndrome (SBS) and intestinal failure (IF) are now surviving into adulthood, there is a paradigm shift from short-term management to long-term outcomes and a growing need to focus on healthcare transition (HCT). It is imperative that adolescents and young adults with SBS and IF receive disease education, empowerment, and support as they navigate the transition from pediatric to adult care. Furthermore, both pediatric and adult healthcare providers who manage these patients should be aware of the challenges faced by this population, barriers to their HCT, and strategies to overcome them. This article reviews the literature on HCT in children with chronic illnesses, discusses barriers to HCT in SBS/IF, identifies the important constituents of the transition process in SBS/IF, and provides recommendations for the successful and smooth transition of the pediatric patient to the adult healthcare environment. Structured and multicomponent HCT programs should become the standard of care to ensure uninterrupted high-quality care across the life span for patients with SBS/IF.

The experiences of adolescent solid organ transplantation recipients, parents, and healthcare professionals in healthcare transition: A qualitative systematic review

PROBLEM

The transition from paediatric-centred to adult healthcare services in adolescent solid organ transplantation recipients is a period of increased risk and vulnerability, the issues related to healthcare transition have become key concerns to the healthcare community.

ELIGIBILITY CRITERIA

Qualitative studies of any design and qualitative components of mixed method studies that explored the experiences of healthcare transition among adolescent solid organ transplant recipients, parents, and healthcare professionals were included.

SAMPLE

Nine articles were finalised and included in the review.

METHODS

A systematic review of qualitative studies was conducted. Databases searched were Scopus, PsycINFO, EMBASE, Web of Science, PubMed, CINAHL and ProQuest Dissertations and Theses. Studies published between the inception of respective database and December 2022 inclusive were considered. A three-step inductive thematic synthesis method outlined by Thomas and Harden was used to form descriptive themes and the 10-item Joanna Briggs Institute Critical Appraisal Checklist was utilised to appraise the quality of included articles.

RESULTS

Two hundred and twenty studies were screened, and 9 studies published between 2013 and 2022 were included. Five analytical themes were generated: 'the struggle of being an adolescent with a transplant'; 'perceptions of transition'; 'the role of parents'; 'lack of transition readiness' and 'the need for better support'.

CONCLUSIONS

Adolescent solid organ transplant recipients, parents, and healthcare professionals faced multiple challenges in the healthcare transition.

IMPLICATIONS

Future interventions and health policies should provide targeted intervention strategies that address the barriers present in the healthcare transition to facilitate the optimization of the youth healthcare transition.

Immunosuppression after pediatric liver transplant: The parents' perspective

BACKGROUND

For children with liver transplants (LT), achieving an "ideal outcome" is a balancing act: too little immunosuppression begets graft injury; too much begets systemic complications. We aimed to delineate the parental perspective on this tightrope.

METHODS

Parents of children with LT completed an internet-based survey about their child's immunosuppression.

RESULTS

Children of respondents (n = 82) were a median 4 years from primary LT (range 0-22); 73% were on immunosuppression monotherapy. Parents' top concerns were related to immunosuppression complications; 46% were more concerned about immunosuppression complications than rejection; only 17% were more concerned about rejection than immunosuppression complications. Among parents of children on immunosuppression monotherapy, 29% still worried more about immunosuppression complications than rejection, 48% expressed equal concern for both. Time since LT (0-4 vs. >4 years) was not associated with concern level for rejection or immunosuppression complications. Caregivers were significantly more certain that their child's immunosuppression regimen was correct to prevent rejection than to mitigate complications (p < .005).

CONCLUSION

Caregivers of children with LTs reported higher levels of concern and uncertainty about immunosuppression complications than rejection risk. Understanding parent and patient perspectives on IS, and incorporating them into immunosuppression counseling and decision-making, is critical to achieving truly "ideal" long-term outcomes.

Health Care Transition for Adolescents and Young Adults With Pediatric-Onset Liver Disease and Transplantation: A Position Paper by the North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition

Advances in medical therapies and liver transplantation have resulted in a greater number of pediatric patients reaching young adulthood. However, there is an increased risk for medical complications and morbidity surrounding transfer from pediatric to adult hepatology and transplant services. Health care transition (HCT) is the process of moving from a child/family-centered model of care to an adult or patient-centered model of health care. Successful HCT requires a partnership between pediatric and adult providers across all disciplines resulting in a transition process that does not end at the time of transfer but continues throughout early adulthood. Joint consensus guidelines in collaboration with the American Society of Transplantation are presented to facilitate the adoption of a structured, multidisciplinary approach to transition planning utilizing The Six Core Elements of Health Care Transition TM for use by both pediatric and adult specialists. This paper provides guidance and seeks support for the implementation of an HCT program which spans across both pediatric and adult hepatology and transplant centers.

Education and Psychosocial Factors Predict Odds of Death After Transfer to Adult health Care in Pediatric Liver Transplant Patients

OBJECTIVES

To analyze demographic, psychosocial, and clinical factors in pediatric liver transplant recipients for their association with death or loss to follow up in adulthood. We aimed to better understand known health disparities in transplant outcomes and identify potentially modifiable risk factors prior to transfer.

METHODS

A retrospective cohort study of children who underwent liver transplantation at a large tertiary transplant center and were transferred to adult care between 2000 and 2015.

RESULTS

During the study period, 101 qualifying patients were transferred. Ninety-three individuals followed with an adult provider, while 8 were lost to follow up. In total 23 of 93 patients died after transfer (24.7%). Several childhood factors were associated with adult death: Black race [odds ratio (OR) 6.59, P < 0.001]; psychiatric illness or substance use (OR 2.81, P = 0.04); failure to graduate high school before transfer (OR 9.59, P < 0.001); posttransplant tacrolimus medication-level variability index >2.5 (OR 5.36, P = 0.04); provider documentation of medication nonadherence (OR 4.72, P = 0.02); acute cellular rejection (OR 4.44, P = 0.03); the presence of diabetes mellitus (OR 5.71, P = 0.001), and chronic kidney disease (OR 2.82, P = 0.04). Failure to graduate HS was associated with loss to follow up ( P < 0.001). On multivariate analysis, Black race, substance use, diabetes, and failure to graduate HS retained association with adult death (each P < 0.05).

CONCLUSIONS

Complex, intertwined patient characteristics are associated with increased odds of death in pediatric liver transplant recipients transferred to adult care. Early recognition of high-risk patients and intervention for modifiable factors, such as improved HS graduation and substance use prevention, may improve long-term outcomes.

A Bibliometric Analysis of the Landscape of Pediatric Liver Transplantation

Background

Nowadays, pediatric liver transplantation (PLT) has become an effective strategy for treating various acute or chronic end-stage liver diseases and inherited metabolic diseases. Many experts have already concluded the current challenges and future directions of PLT. However, no detailed analysis of the publication landscape has substantiated these proposed opinions.

Methods

This study presents a bibliometric review of the articles related to PLT between 1997 and 2020. A total of 3,084 publications were analyzed mainly by CiteSpace and VOSviewer.

Results

The field of PLT has evolved gradually in the past two decades. Articles increased at an average rate of 97 articles every 4 years. University of Pittsburgh (PITT) is the most prolific institution. The three most productive regions are North America, Europe, and East Asia. Currently, interdisciplinary studies on PLT are scarce. The main goal of PLT has shifted from survival rates to long-term outcome. The quality of life, living donor liver transplantation (LDLT), immunological biomarkers, perioperative hemodynamic management, expanding the indications of PLT, etc. are parts of the emerging research fronts. In the past two decades, articles that contain potentials that may lead to transformative discoveries are scarce, and obvious deficits can be seen in the field of new therapies.

Conclusions

Long-term outcome and good quality of life represent the principal direction of work concerning PLT. Deficits in new therapies align with the shortage of intellectual milestones, which indicate possible subsequent intellectual milestones may occur as innovations in therapies such as new immunosuppression therapies or liver cell transplantation.

Not everything that counts can be counted: Tracking long-term outcomes in pediatric liver transplant recipients

For pediatric liver transplant (LT) recipients, an ideal outcome is to survive and thrive into adulthood. However, outcomes reporting for all LT recipients typically rely on much shorter-term outcomes, 1-5 years post-LT. Using Organ Procurement and Transplantation Network (OPTN) registry data from 1990 to 2018, this analysis seeks to determine if long-term follow-up and outcome data are complete for pediatric LT recipients age 0 to 12 years who survive at least 1 year post-LT without graft loss (n = 9309). Of the 7948 pediatric transplant recipients who did not die or require re-LT, 1 in 6 was reported as lost to follow-up by their transplant center during long-term follow-up. Rates of lost to follow-up were highest in those transplanted between 1990 and 1999 and increased in early adulthood for all recipients. Almost 10% of pediatric LT recipients who remained in follow-up required relisting for LT. 8% of children remaining in follow-up had graft failure. Lost to follow-up may bias estimates of long-term outcomes and risk factors for poor outcomes. For those remaining in follow-up, graft failure and death continue to occur in the decades after LT. Continued proactive monitoring, management, and innovations are needed to truly optimize post-LT survival for all children.

Recurrence of Primary Sclerosing Cholangitis After Liver Transplant in Children: An International Observational Study

BACKGROUND AND AIMS

Recurrent primary sclerosing cholangitis (rPSC) following liver transplant (LT) has a negative impact on graft and patient survival; little is known about risk factors for rPSC or disease course in children.

APPROACH AND RESULTS

We retrospectively evaluated risk factors for rPSC in 140 children from the Pediatric PSC Consortium, a multicenter international registry. Recipients underwent LT for PSC and had >90 days of follow-up. The primary outcome, rPSC, was defined using Graziadei criteria. Median follow-up after LT was 3 years (interquartile range 1.1-6.1). rPSC occurred in 36 children, representing 10% and 27% of the subjects at 2 years and 5 years following LT, respectively. Subjects with rPSC were younger at LT (12.9 vs. 16.2 years), had faster progression from PSC diagnosis to LT (2.5 vs. 4.1 years), and had higher alanine aminotransferase (112 vs. 66 IU/L) at LT (all P < 0.01). Inflammatory bowel disease was more prevalent in the rPSC group (86% vs. 66%; P = 0.025). After LT, rPSC subjects had more episodes of biopsy-proved acute rejection (mean 3 vs. 1; P < 0.001), and higher prevalence of steroid-refractory rejection (41% vs. 20%; P = 0.04). In those with rPSC, 43% developed complications of portal hypertension, were relisted for LT, or died within 2 years of the diagnosis. Mortality was higher in the rPSC group (11.1% vs. 2.9%; P = 0.05).

CONCLUSIONS

The incidence of rPSC in this cohort was higher than previously reported, and was associated with increased morbidity and mortality. Patients with rPSC appeared to have a more aggressive, immune-reactive phenotype. These findings underscore the need to understand the immune mechanisms of rPSC, to lay the foundation for developing new therapies and improve outcomes in this challenging population.

African American Pediatric Liver Transplant Recipients Have an Increased Risk of Death After Transferring to Adult Healthcare

OBJECTIVE

To analyze the long-term outcomes in pediatric liver transplant recipients after they have transferred to an adult provider and assess for racial disparities in health outcomes.

STUDY DESIGN

This is a single-center, retrospective review of pediatric patients who underwent liver transplantation between July 1990 and August 2015 at a tertiary healthcare system with a large transplant center. Patient mortality and retransplantation were assessed after transfer to adult care.

RESULTS

There were 120 patients who were transferred, of whom 19 did not meet the inclusion criteria. Of the remaining 101 patients, 64 (63%) transferred care to a nearby affiliated tertiary adult facility, 29 (29%) were followed by other healthcare systems, and 8 (8%) were lost to follow-up. Of the patients followed at our affiliated adult center, 18 of the 64 (28%) died. Of those 18 deaths, 4 (22%) occurred within the first 2 years after transfer, and 10 (55%) within 5 years of transfer. Four patients were retransplanted by an adult provider, of whom 2 eventually received a third transplant. African Americans had higher rates of death after transfer than patients of other races (44% mortality vs 16%, representing 67% of all cases of death; P = .032), with nearly 50% mortality at 20 years from time of transplantation.

CONCLUSIONS

Death is common in pediatric liver transplant recipients after transfer to adult care, with African Americans having disproportionately higher mortality. This period of transition of care is a vulnerable time, and measures must be taken to ensure the safe transfer of young adults with chronic health care needs.

Predicting Suboptimal Transitions in Adolescents With Inflammatory Bowel Disease

OBJECTIVES

Adolescents and young adults (AYAs) are at risk for disease exacerbations and increased health care utilization around the time of transition to adult care. Our aim was to identify risk factors predictive of a suboptimal transition for AYA with inflammatory bowel disease.

MATERIALS AND METHODS

We performed a retrospective chart review of patients with pediatric inflammatory bowel disease transferred to adult care from our institution in 2016 and 2017, recording demographic, psychosocial, and disease-specific data. Post-transfer data were obtained via the health care information exchange from the adult provider within our electronic medical record. We defined suboptimal transition as either a return to pediatric care or requiring care escalation within 1 year of transfer.

RESULTS

Out of 104 subjects 37 (36%) were found to have had a suboptimal transition. Our models suggest that a suboptimal transition is associated with several risk factors including any mental health diagnosis (odds ratio [OR] = 4.15; 95% confidence interval [95% CI]: 1.18-14.59), history of medication nonadherence (OR = 5.15 [95% CI: 1.52-17.42]), public insurance (OR = 6.60 [95% CI: 1.25-34.96]), higher Physician Global Assessment score at time of transition (OR = 6.64 [95% CI: 1.60-27.58], and short Pediatric Crohn Disease Activity Index scores (OR = 1.17 [95% CI: 1.03-1.33]). Higher hemoglobin levels at transition were protective (OR = 0.69 [95% CI: 0.48-0.98]). Age at time of transition, disease duration, and medication type at transition were not found to be associated with transition outcomes.

CONCLUSION

AYA with public insurance, a mental health history, medication nonadherence, and evidence of active disease may be at greater risk for suboptimal and poor health outcomes at transition.

A multidisciplinary approach to improving transition readiness in pediatric liver transplant recipients

The Six Core Elements of Transition have been advocated to guide transition, but little is published about their use with liver transplant patients. We started a liver transplant transition program in August 2015 using quality improvement (QI) methods and by linking the Six Core Elements of Transition to process measures. Eligible patients completed baseline transition readiness assessments (Readiness for Transition Questionnaire, RTQ), interviews with a psychologist, received focused education, and completed follow-up RTQs before transfer to adult care. Our QI goal was to improve RTQ scores by 20% prior to transfer to adult care. We also assessed continuity of care, tacrolimus levels, rejection, and retransplantation as balancing measures. Of the 24 patients who completed the transition program and were transferred to adult care, RTQ scores were available for 11 patients. Overall RTQ scores improved from 23.7 to 30.5 (+28.7%, P = .009) prior to transfer. Nearly two-thirds (63%) of patients were seen by adult transplant hepatology within 6 months, and one patient was lost to follow-up after the first adult visit. Tacrolimus-level standard deviations were <2.0 in 45% of patients in pediatric care and 72% of patients in adult care. Three patients had undergone immunosuppression withdrawal in pediatric care, with one restarted on immunosuppression prior to transfer to adult care due to late acute rejection. The Six Core Elements of Transition can be translated into patient- and system-level transition milestones to serve as potential quality metrics in the implementation of transition programs.

TRANSITION of Pediatric Liver Transplant Patients to Adult Care: a Review

PURPOSE OF REVIEW

Many pediatric liver transplant patients are surviving to adulthood, and providers have come to recognize the importance of effectively transitioning these patients to an adult hepatologist. The review aims to analyze the most recent literature regarding patient outcomes after transition, barriers to successful transition, recommendations from clinicians and medical societies regarding transition programs, and to provide personal insights from our experience in transitioning liver transplant recipients.

RECENT FINDINGS

While results were variable between studies, many recent reports show significant morbidity and mortality in patients following transition to adult care. Medical non-adherence is frequently seen in adolescents and young adults both prior to and after transition, and is consistently associated with higher rates of rejection, graft loss, and death. In general, transplant programs with a formal transition process had better patient outcomes though recent findings are mostly-single center and direct comparison between programs is difficult. Societal recommendations for how to create a transition program contain a number of common themes that we have categorized for easier understanding. Successful transition is vital to the continued health of pediatric liver transplant patients. While an effective transition program includes a number of key components, it should be individualized to best function within a given transplant center. Here, we have reviewed a number of recent single-center retrospective studies on transition, but multi-site retrospective or prospective data is lacking, and is a fertile area for future research.

Health Care Transition: A Time of Increased Vulnerability for Pediatric Liver Transplant Recipients

Improvements in pediatric liver transplantation (LT) have led to an increased number of patients reaching young adulthood. Young adult LT recipients transferring from pediatric to adult models of care have increased rates of rejection, graft loss, and medical complications. The goal of a health care transition program is to optimize health and assist youth in reaching their full potential. The means to achieve this goal requires an organized transition process to support youth in acquiring independent health care skills, preparing for an adult model of care, and transferring to new providers without disruption in treatment. This can only be achieved through a multidisciplinary approach to transition planning. This is often a labor and resource-intensive undertaking, which may not receive the necessary support from local institutions. Widespread implementation requires the assistance and endorsement from governing organizations at the national and international level.
