Development and validation of the pediatric liver transplantation quality of life: a disease-specific quality of life measure for pediatric liver transplant 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 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.

Adult provider role in transition of care for young adult pediatric recipients of liver transplant: An expert position statement

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.

Determining the minimally clinically important difference for the pediatric liver transplant quality of life questionnaire

PURPOSE

The Pediatric Liver Transplant Quality of Life (PeLTQL) questionnaire is a disease-specific patient reported outcome measure for pediatric liver transplant (LT) recipients. To-date, threshold values above which a change in PeLTQL score is considered meaningful to patients are unavailable. This study proposes the first values for the minimally clinically important difference (MCID) for the PeLTQL.

METHODS

In this retrospective cohort study, anchor and distribution-based methods were used to estimate the MCID for the PeLTQL. Questionnaires completed between March 2013, and July 2022 were included if data from two sequential visits were available. An internal anchor question was used for anchor-based determination of the MCID. A final MCID estimate was ascertained from triangulation of all methods.

RESULTS

PeLTQL data from 65 LT recipients (26 [40%] male, 17 [42%] biliary atresia, median age at LT 3.08 years [interquartile range 0.99-7.30]), and their caregivers were included for analysis. Median patient age at time of baseline PeLTQL completion was 13.84 (10.90-15.86) years. The MCID for self-PeLTQL total scores ranged from 4.53 to 8.46, and from 4.47 to 8.85 for proxy responses. By triangulation, the MCID of the PeLTQL total score was 6.45 and 6.78 for self and proxy responses respectively.

CONCLUSION

A change in PeLTQL score of 6.5 or more points suggests a change in health status that is meaningful to the patient, providing the clinical team an opportunity to engage the patient's voice in reassessing current health status and management strategies.

Immunosuppression-Free Life after Pediatric Liver Transplant: A Case-Control Study from the Society of Pediatric Liver Transplant (SPLIT) Registry

OBJECTIVE

To compare long-term outcomes of pediatric liver transplant (LT) recipients off immunosuppression (IS) with matched controls on IS using data from the Society of Pediatric Liver Transplant (SPLIT) registry.

STUDY DESIGN

This was a retrospective case-control study. SPLIT participants <18 years of age, ≥4 years after isolated LT, and off IS for ≥1 year (cases) were age- and sex-matched 1:2 to patients with the same primary diagnosis and post-LT follow-up duration (controls). Primary outcomes included retransplantation, allograft rejection, IS comorbidities, and prevalence of SPLIT-derived composite ideal outcome (c-IO) achieved at the end of the follow-up period. Differences were compared using multiple linear regression for continuous outcomes and logistic regression for dichotomous data.

RESULTS

The study cohort was composed of 33 cases (42.4% male, 60.6% biliary atresia, median age at LT of 0.7 [P25, P75, 0.5, 1.6] years, median IS withdrawal time of 9 [P25, P75, 6, 12] years after LT) and 66 age- and sex-matched controls. No cases required retransplantation. Cases and controls had similar growth parameters, laboratory values, calculated glomerular filtration rates, rates of post-transplant lymphoproliferative disease, graft rejection, and attainment of c-IO.

CONCLUSIONS

No differences in allograft rejection rates, IS complications, or c-IO prevalence were seen between SPLIT patients off IS and age- and sex-matched controls remaining on IS. Discontinuation of IS most commonly occurred in the context of rigorously designed IS withdrawal trials. The available sample size was small, affecting generalizability to the broader pediatric LT population.

Neurometabolic changes in a rat pup model of type C hepatic encephalopathy depend on age at liver disease onset

Chronic liver disease (CLD) is a serious condition where various toxins present in the blood affect the brain leading to type C hepatic encephalopathy (HE). Both adults and children are impacted, while children may display unique vulnerabilities depending on the affected window of brain development.We aimed to use the advantages of high field proton Magnetic Resonance Spectroscopy (1H MRS) to study longitudinally the neurometabolic and behavioural effects of Bile Duct Ligation (animal model of CLD-induced type C HE) on rats at post-natal day 15 (p15) to get closer to neonatal onset liver disease. Furthermore, we compared two sets of animals (p15 and p21-previously published) to evaluate whether the brain responds differently to CLD according to age onset.We showed for the first time that when CLD was acquired at p15, the rats presented the typical signs of CLD, i.e. rise in plasma bilirubin and ammonium, and developed the characteristic brain metabolic changes associated with type C HE (e.g. glutamine increase and osmolytes decrease). When compared to rats that acquired CLD at p21, p15 rats did not show any significant difference in plasma biochemistry, but displayed a delayed increase in brain glutamine and decrease in total-choline. The changes in neurotransmitters were milder than in p21 rats. Moreover, p15 rats showed an earlier increase in brain lactate and a different antioxidant response. These findings offer tentative pointers as to which neurodevelopmental processes may be impacted and raise the question of whether similar changes might exist in humans but are missed owing to 1H MRS methodological limitations in field strength of clinical magnet.

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.

Feasibility of using a patient-reported outcome measure into clinical practice following pediatric liver transplantation: The Starzl Network experience

BACKGROUND

Patient-reported outcome measures (PROMs) are not routinely used in clinical care by pediatric liver transplant (LT) teams. The Starzl Network for Excellence in Pediatric Transplantation (SNEPT) assessed feasibility of using a disease-specific Quality of Life (QoL) questionnaire in the ambulatory setting at 10 SNEPT sites.

METHODS

A mixed methods feasibility project assessing administration processes, barriers, and user experiences with the Pediatric Liver Transplant Quality of Life (PeLTQL) tool. Iterative processes sought stakeholder feedback across four phases (Pilot, Extended Pilot, Development of a Mobile App PeLTQL version, and Pilot App use).

RESULTS

A total of 149 patient-parent dyads completed the PeLTQL during LT clinic follow-up. Clinicians, parents, and patients evaluated and reported on feasibility of operationalization. Only two of 10 SNEPT sites continued PeLTQL administration after the initial two pilot phases. Reasons include limited clinical time and available personnel aggravated by the COVID-19 pandemic. In response, a mobile application version of the PeLTQL was initiated. Providing PeLTQL responses electronically was "very easy" or "easy" as reported by 96% (22/23) parents.

CONCLUSIONS

Administration of a PROM into post-pediatric LT clinical care was feasible, but ongoing utilization stalled. Use of a mobile app towards facilitating completion of the PeLTQL outside of clinic hours may address the time and work-flow barriers identified.

Equivalence of Paper and Electronic-Based Patient Reported Outcome Measures for Children: A Systematic Review

Patient-reported outcome measures (PROMs) exist for a variety of chronic gastrointestinal disorders in children. The availability of electronic (e-)formats of PROMs enhance the accessibility of these tools. The International Society for Pharmacoeconomic and Outcomes Research (ISPOR) defines measurement equivalence (ME) as "comparability of the psychometric properties of data" obtained from the administration of original and adapted versions of PROMs. Consideration of proxy PROM versions is unique to pediatrics and must be included in ME evaluations. We conducted a systematic review (SR) of the literature evaluating ME of e-versions adapted from pediatric paper-based PROMs. A literature search was conducted through Medline, Embase, APA PsychInfo, and the Cochrane Library. Titles, abstracts, and manuscripts were reviewed by 2 independent reviewers. The search yielded 19 studies meeting pre-defined criteria. Just over half (52.6%) of 19 PROMs were disease-specific ones. ME between paper- and e-PROM versions was reported as present in all 19 studies evaluating 5653 participants under the age of 18 years. However, only 6 (31.6%) studies evaluated ME in proxy reported e-versions. Despite the use of PROMs for children with a variety of chronic gastrointestinal disorders, only 1 study evaluated a PROM in this population (IMPACT III for inflammatory bowel disease). Findings from this SR highlight strategic opportunities for the pediatric gastroenterologist to broaden the clinical and research armamentarium to include e-PROMs.

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.

Long-Term Cognitive Outcomes and Associated Quality of Life of Young Adults Who Experienced Liver Transplantation in Early Childhood

We evaluated long term outcomes in infants born between 1992 and 2002 with cholestatic liver disease (CLD) who underwent successful liver transplantation (LT). A total of 160 children with CLD were identified: 68 had developmental assessments before and after LT of whom 32 were excluded because they were followed up elsewhere; 16/36 consented to complete measures of IQ, anxiety, depression, health related quality of life (HRQoL), and a habits/employment survey. Illness severity and developmental attainment prior to LT were comparable with the 32 excluded and 20 patients who declined to take part. The IQ of young adults after LT (mean score = 91.13, range 75-108, SD 10.4) was not significantly improved compared to pre-LT scores (mean score = 85.7 range 50-111, SD 17), but was inversely correlated with stunting of growth and duration of disease before LT, highlighting the need for timely LT in CLD. HRQoL scores ranged from 22 to 99 (mean 64.5 SD 20.7), comparable to scores in other LT recipients. Five (31%) had mild-moderate depression; 5 (31%) had moderate-severe anxiety associated with reduced HRQoL (P = 0.01 and P = 0.06, respectively); and nine had problematic fatigue which correlated with reduced HRQoL (r 2 = 0.4 P = 0.007). Reduced medication adherence was associated with fatigue (Spearman correlation r 2 = 0.267; P = 0.09) and anxiety (Spearman correlation r 2 = 0.597; P = 0.02). Raised body mass index was also associated with reduced and health-related quality of life scores PeLTQL© (r 2 = 0.379 P = 0.011). Fifteen (94%) were undergoing education or were employed. The long-term neuro-cognitive and psychosocial outcomes of young adults transplanted as babies is encouraging, although anxiety/depression was more common than in the healthy population. Psychosocial questionnaires help identify those young adult LT recipients who may benefit from support.

Parental Disease Specific Knowledge and Its Impact on Health-Related Quality of Life

OBJECTIVE

Structured education programs have been shown to improve somatic outcome and health-related quality of life (HRQOL) in a variety of chronic childhood diseases. Similar data are scarce in paediatric liver transplantation (pLTx). The purpose of this study was to examine the relationship of parental disease-specific knowledge and psychosocial disease outcome in patients after pLTx.

METHODS

Parents of 113 children (chronic liver disease n = 25, after pLTx n = 88) completed the transplant module of the HRQOL questionnaire PedsQL, the "Ulm quality of life inventory for parents of children with chronic diseases" ULQUI, and a tailor-made questionnaire to test disease-specific knowledge.

RESULTS

Parental knowledge was highest on the topic of "liver transplantation" and lowest in "basic background knowledge" (76% and 56% correct answers respectively). Knowledge performance was only marginally associated with HRQOL scores, with better knowledge being related to worse HRQOL outcomes. In contrast, self-estimation of knowledge performance showed significant positive correlations with both PedsQL and ULQUI results.

CONCLUSION

Patient HRQOL and parental emotional wellbeing after pLTx are associated with positive self-estimation of parental disease-specific knowledge. Objective disease-specific knowledge has little impact on HRQOL. Parental education programs need to overcome language barriers and address self-efficacy in order to improve HRQOL after pLTx.

The effects of child anxiety and depression on concordance between parent-proxy and self-reported health-related quality of life for pediatric liver transplant patients

BACKGROUND

HRQOL is a key outcome following pediatric LT. Parent-proxy reports may substitute for patients unable to report their own HRQOL. This study compared parent-proxy and self-reported HRQOL in children who have undergone LT.

METHODS

Pediatric LT recipients between the ages of 8 and 18 years, and a parent, completed self and proxy versions of the PeLTQL questionnaire, PedsQL Generic and Transplant modules, and standardized measures of depression and anxiety.

RESULTS

Data from 129 parent-patient dyads were included. Median parent age was 44 years, and most (89%) were mothers. Median patient age was 2.5 years at LT and 13.6 years at the time of study participation. Parents had significantly lower scores than patients on PedsQL total generic (70.8 ± 18.5 and 74.3 ± 19.0, p = .01), PeLTQL coping and adjustment (63.0 ± 15.6 and 67.3 ± 16.2, p < .01), and social-emotional (66.3 ± 14.9 and 71.9 ± 15.6, p < .001) domains. Higher patient anxiety and depression were related to larger absolute differences between parent-proxy and self-reported scores on all HRQOL measures (all p < .05). In this disparity, parents reported higher HRQOL scores than their child as self-reported anxiety and depression scores increased.

CONCLUSIONS

Differences in concordance between parent-proxy and self-reported HRQOL scores can be more prominent when children have more symptoms of anxiety and depression. Children's mental health symptoms should be queried, if feasible, when interpreting differences in parent and child reports of HRQOL.

Improvements in Disease-Specific Health-Related Quality of Life of Pediatric Liver Transplant Recipients During Immunosuppression Withdrawal

Long-term immunosuppression (IS) leads to systemic complications affecting health-related quality of life (HRQOL) in pediatric liver transplantation (LT) recipients. We serially assessed HRQOL using the PedsQL Generic and Multidimensional Fatigue Scales and Family Impact and Transplant Modules as part of a multicenter prospective immunosuppression withdrawal (ISW) trial between 2012 and 2018. Participants received a primary LT ≥4 years before the study and were on stable IS with normal liver tests and without rejection in the prior 2 years. IS was withdrawn in 7 steps over 36 to 48 weeks. HRQOL was assessed at regular intervals. The primary endpoint was change in disease-specific HRQOL measured by the PedsQL Transplant Module. Generic HRQOL was measured by the PedsQL Generic Scale and was compared with an age-matched and sex-matched multicenter cohort. Of the 88 participants, 39 were boys, median age was 11 years (range, 8-13), and time since transplant was 9 years (range, 6-11). For 36 months, disease-specific HRQOL improved for all participants, whereas generic HRQOL was unchanged. Neither generic nor disease-specific HRQOL changed for the 35 participants who developed acute rejection during ISW. In the first use of patient-reported outcome measures during an ISW trial, we found improvements in disease-specific HRQOL in all participants and no lasting detrimental effects in those who experienced rejection.

Engaging the Voices of Children: A Scoping Review of How Children and Adolescents Are Involved in the Development of Quality-of-Life-Related Measures

OBJECTIVES

Patient-reported outcomes are increasingly recommended to guide patient care, develop and evaluate interventions, and modify health systems. However, not enough is known about whether and how children and adolescents, as "experts" in their own health and quality of life (QoL), are being engaged in the development of instruments. Our goals in this review were (1) to identify all QoL-related instruments that have included children and/or adolescents in the development of questionnaire content, including identification of themes and items; and (2) to report how this was done; and (3) to highlight those that used qualitative methods.

METHODS

MEDLINE and Embase were searched for child- or adolescent-completed QoL-related instruments, supplemented by hand-searching of relevant reviews until 2020. Original development papers were identified and retrieved when possible, from which instrument characteristics and details of qualitative development methods were extracted.

RESULTS

We identified 445 instruments, of which 88 used qualitative methods for content development. Interviews and focus groups were the most common methods. A variety of play techniques were used to engage the child and adolescent participants. The specific criteria for the inclusion of children and adolescents (age, developmental stage, duration, and nonclinical location) varied considerably.

CONCLUSIONS

Researchers frequently involve children and adolescents in qualitative methods when developing QoL-related measures; however, there is little information about the methods used. Better reporting of methodology, improved dissemination of methods guidelines, and research into optimal ways of including children and adolescents in the process of instrument development would be useful.

A Learning Health System for Pediatric Liver Transplant: The Starzl Network for Excellence in Pediatric Transplantation

OBJECTIVE

Learning health systems (LHS) integrate research, improvement, management, and patient care, such that every child receives "the right care at the right time...every time," that is, evidence-based, personalized medicine. Here, we report our efforts to establish a sustainable, productive, multicenter LHS focused on pediatric liver transplantation.

METHODS

The Starzl Network for Excellence in Pediatric Transplantation (SNEPT) is the first multicenter effort by pediatric liver transplant families and providers to develop shared priorities and a shared agenda for innovation in clinical care. This report outlines SNEPT's structure, accomplishments, and challenges as an LHS.

RESULTS

We prioritized 4 initial projects: immunosuppression, perioperative anticoagulation, quality of life, and transition of care. We shared center protocols/management to identify areas of practice variability between centers. We prioritized actionable items that address barriers to providing "the right care at the right time" to every pediatric liver transplant recipient: facilitating transparency of practice variation and the connection of practices to patient outcomes, harnessing existing datasets to reduce the burden of tracking outcomes, incorporating patient-reported outcomes into outcome metrics, and accelerating the implementation of knowledge into clinical practice. This has allowed us to strengthen collaborative relationships, design quality improvement projects, and collect pilot data for each of our priority projects.

CONCLUSIONS

The field of pediatric liver transplantation can be advanced through application of LHS principles. Going forward, SNEPT will continue to unite patient advocacy, big data, technology, and transplant thought leaders to deliver the best care, while developing new, scalable solutions to pediatric transplantation's most challenging problems.

Health-Related Quality of Life 10 Years after Liver Transplantation: A Longitudinal Retrospective Review

As survival post-liver transplantation (LTx) improves, it becomes increasingly important to understand how long-term health-related quality of life (HRQOL) is impacted. This was a longitudinal review examining HRQOL measured by Pediatric Liver Transplant Quality of Life (PeLTQL) in children between 8-17 years who underwent LTx (1.4 [0.8–3.3] years) at least one year prior to assessment. Demographic, medical, anthropometric, and HRQOL data (self-reported and parent proxy) were retrospectively collected over four years (2014–2017) at annual LTx clinic visits. The study included 35 patients (18M, 17F) and their parents/guardians. Parent-proxy and child PeLTQL scores (total, subdomain) showed good to excellent agreement (p > 0.05) and did not change over four years (p > 0.05). Younger age (<12 years) and Caucasian ancestry were associated with higher parental and self-reported perceptions of HRQOL, respectively (future health, coping and adjustment, total scores). Parent perceived lower HRQOL in social–emotional sub-domain (p = 0.03) and the child reported lower sub-domain scores related to coping and adjustment (p = 0.04) when the child was noted to have co-morbid conditions related to mental health and neurocognitive development (25.7%). While child–parent perceptions of HRQOL in a multi-ethnic population of pediatric LTx recipients remain unchanged 10 years post-LTx, adolescents of non-Caucasian ancestry remain a population at risk for lower HRQOL.

What is the long-term outlook for young people following liver transplant? A single-centre retrospective analysis of physical and psychosocial outcomes

LT is a successful treatment for end-stage liver disease. The long-term outcome of patients transplanted in childhood has not previously been widely reported. This project assessed the long-term impact of transplantation in patients surviving >15 years. Retrospective data on growth, end-organ damage and psychosocial development were collected in young people transplanted from 1985 to 2000 in a single centre. Clinical notes were reviewed, and patients interviewed at clinic follow-up. 224 patients were transplanted between 1985 and 2000. 143 recipients (63.8%) survived >15 years with a median survival of 19.52 years. The majority were well, and only 10% had abnormal graft function (biochemical/synthetic), the main cause of which was chronic hepatitis (6%). Renal dysfunction and the necessity for renal transplant were identified in 32.8%, of whom 16.7% of patients had a cGFR <70 mL/min/1.73 m² and 6% of patients had either undergone or awaiting renal transplant. This cohort was healthier than the average age-matched UK population in terms of body mass index (9% obese), smoking and alcohol consumption. 92% of patients had completed or were in education (93/123 had completed education and 20/123 remained in school). 63.7% of patients had been transitioned into adult services, and 46.3% of these patients were employed. 67.5% were in a relationship, one patient was divorced, and 10.6% of patients had one or more children. 11 patients had symptoms that corresponded to a DSM IV diagnosis of depression. Four patients had anorexia nervosa. Developmental delay was identified in 9 out of 99 patients. The development of malignancy, including PTLD, occurred in 10/143 (7%) patients at a median time post-transplant of 2.76 years (range 0.76-9.06 years). Epstein-Barr infection was implicated in 75% of these malignancies. We conclude the long-term outcome of LT in childhood is good with 63.8% surviving into adulthood and over 60% transferring into adult services. Graft dysfunction and end organ damage are minimal. Our cohort is healthier than the general population, and the majority have completed education, sought employment and formed relationships with peers, contributing well to society.

It takes a village: primary care of the pediatric liver transplant recipient

PURPOSE OF REVIEW

Long-term survival is now the rule rather than the exception for infants and children who undergo liver transplantation for end-stage liver disease, metabolic liver conditions and a variety of other indications. Pediatricians and primary care providers play vital roles in the care and management of this patient population. The purpose of this review is to highlight key aspects important to the care of the pediatric liver transplant recipient.

RECENT FINDINGS

Significant advances in immunosuppressive therapies and surgical techniques have contributed to improved graft and patient survival rates, shifting the focus beyond immediate survival to strategies to minimize comorbidities related to long-term immunosuppression during growing years, attend to patient and parent-reported outcomes and enhance quality of life. A multidisciplinary approach allows for monitoring and surveillance of both routine (growth, nutritional rehabilitation, cognitive development, mental and psychosocial health, contraception and daily activities) and transplant-related (adverse effects of immunosuppression, susceptible infections, extra-hepatic systems, transition from childhood to adolescence to adulthood) themes.

SUMMARY

Effective communication between the primary care physician and the transplant team is imperative for optimizing best outcomes. The primary care provider should be aware of the multifacet nature of posttransplant management, which includes medication regimens, common complications and infections.

Barriers to ideal outcomes after pediatric liver transplantation

Long-term survival for children who undergo LT is now the rule rather than the exception. However, a focus on the outcome of patient or graft survival rates alone provides an incomplete and limited view of life for patients who undergo LT as an infant, child, or teen. The paradigm has now appropriately shifted to opportunities focused on our overarching goals of "surviving and thriving" with long-term allograft health, freedom of complications from long-term immunosuppression, self-reported well-being, and global functional health. Experts within the liver transplant community highlight clinical gaps and potential barriers at each of the pretransplant, intra-operative, early-, medium-, and long-term post-transplant stages toward these broader mandates. Strategies including clinical research, innovation, and quality improvement targeting both traditional as well as PRO are outlined and, if successfully leveraged and conducted, would improve outcomes for recipients of pediatric LT.

Patient-reported outcome measures within pediatric solid organ transplantation: A systematic review

Subjective evaluation of medical care and disease outcomes from patients' perspectives has become increasingly important. Patient-reported outcome measures (PROMs) play a prominent role in engaging patients, capturing their experiences and improving patient care. This systematic review sought to identify PROMs that are used in the field of pediatric solid organ transplantation, with the aim to inform the implementation of PROMs into clinical practice for this population. A systematic review of English language, peer-reviewed articles was performed on key health science databases to identify publications using PROMs in pediatric solid organ transplantation. The search yielded 3670 articles, with a final data set of 62 articles that included 47 different PROMs. The three most frequently used PROMs included the following: (a) PedsQL™ Generic Core Scales (n = 25); (b) Children's Depression Inventory (n = 6); and (c) Child Health Questionnaire (n = 6). Of the 47 PROMs, 42 were generic and five were disease-specific; only six PROMS had a documented psychometric evaluation within a pediatric solid organ transplant population. This review outlines the attributes of the instruments (eg, domains captured), as well as the psychometric properties of those evaluated. PROMs are increasingly used in the field of pediatric transplantation; however, there are limited details in the current literature about their conceptual underpinnings and psychometric properties. This review highlights the need for additional psychometric evaluation of identified measures to establish the necessary foundation to inform the implementation of PROMs into clinical care for pediatric solid organ transplant patients.

Health-related quality of life in pre-adolescent liver transplant recipients with biliary atresia: A cross-sectional study

OBJECTIVE

Pediatric recipients of liver transplantation (LT) often report lower Health-Related Quality of Life (HRQOL) than healthy controls when assessed on generic HRQOL measurement tools. The recent addition of the Pediatric Liver Transplant Quality of Life (PeLTQL), a novel disease-specific HRQOL instrument for pediatric LT recipients, into the clinical armamentarium of tools now routinely available to clinical care teams, provides the unique opportunity to identify disease-related challenges in children who have undergone this life-saving intervention. This study assesses HRQOL in pre-adolescent aged patients with a primary diagnosis of biliary atresia (BA) who underwent LT as an infant, using both generic and disease-specific HRQOL instruments validated for children. We also examined modifiable factors associated with HRQOL after pediatric LT.

METHODS

HRQOL was the primary outcome of this study assessed using the disease-specific PeLTQL and the generic Pediatric Quality of Life Inventory 4.0 (PedsQL). Exposure variables of interest included medication status (e.g., monotherapy, dual therapy) and participation in sports.

RESULTS

A total of 70 (56% female, mean age 9.89 ± 1.25 years) pediatric LT recipients (mean interval since LT was 9.0 ± 1.26 years) comprised the study cohort. LT recipients reported significantly lower PedsQL Scores relative to the general population. Immunosuppression monotherapy was associated with higher patient-reported PeLTQL Scores, and sports participation was associated with higher parent-reported PedsQL Scores.

CONCLUSIONS

Pre-adolescents who underwent LT as an infant with BA, self-report low HRQOL on both disease-specific and generic HRQOL tools. Further research targeting sports participation and simplifying immunosuppression may further optimize quality of life years restored by life-saving LT.

What does the Cantril Ladder measure in adolescence?

INTRODUCTION

The Cantril Scale (CS) is a simple visual scale which makes it possible to assess general life satisfaction. The result may depend on the health, living, and studying conditions, and quality of social relations. The objective of this study is to identify key factors influencing the CS score in Polish adolescents.

MATERIAL AND METHODS

The survey comprised 1,423 parent-child pairs (54% girls; age range: 10-17; 67.3% urban inhabitants; 89.4% of parents were mothers). Linear and logistic models were estimated; the latter used alternative divisions into "satisfied" and "dissatisfied" with life. In addition to age and gender, child-reported KIDSCREEN-52 quality of life indexes were taken into account, along with some information provided by parents - child physical (CSHCN) and mental (SDQ) health, and family socio-economic conditions.

RESULTS

According to the linear model, nine independent predictors, including six dimensions of KIDSCREEN-52, explain 47.2% of the variability of life satisfaction on the Cantril Scale. Self-perception was found to have a dominating influence (ΔR² = 0.301, p < 0.001). Important CS predictors also included Psychological Well-being (ΔR² = 0.088, p < 0.001) and Parent Relations (ΔR² = 0.041, p < 0.001). The impact of socioeconomic factors was more visible in boys and in older adolescents. According to logistic models, the key factors enhancing the chance of higher life satisfaction are Moods and Emotions (cut-off point CS > 5) and School Environment (CS > 8 points). None of the models indicated a relationship between the CS and physical health.

CONCLUSIONS

The Cantril Scale can be considered a useful measurement tool in a broad approach to psychosocial adolescent health.

Early and Late Factors Impacting Patient and Graft Outcome in Pediatric Liver Transplantation: Summary of an ESPGHAN Monothematic Conference

As pediatric liver transplantation comes of age, experts gathered to discuss current paradigms and define gaps in knowledge warranting research to further improve patient and graft outcomes. Identified areas ripe for collaborative research include understanding the molecular and cellular mechanisms of tolerance and the role of donor-specific antibodies, considering ways to expand donor pool, minimizing long-term side effects of immunosuppression, and fine-tuning surgical techniques to minimize biliary and vascular complications.

Health-related quality of life after pediatric liver transplantation: A systematic review

With improved survival rates after pediatric liver transplantation (LT), attention is targeting improving the health-related quality of life (HRQOL) as an outcome metric. We conducted a systematic review of the literature to examine HRQOL after pediatric LT, focusing on assessment tools and factors associated with HRQOL. A literature search was conducted through PubMed, Web of Science, Ovid, and Google Scholar for all studies matching the eligibility criteria between January 2004 and September 2016. Titles and abstracts were screened independently by 2 authors and consensus for included studies was achieved through discussion. A total of 25 (2 longitudinal, 23 cross-sectional) studies were reviewed. HRQOL in pediatric LT recipients is lower than healthy controls, but it is comparable to children with chronic diseases or other pediatric solid organ transplant recipients. Domain scores were lowest in school functioning on the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scale 4.0 and general health perception on the Child Health Questionnaire, the 2 most commonly used generic HRQOL instruments. Identified predictors of poor HRQOL include sleep disturbances, medication adherence, and older age at transplantation. Two recently validated disease-specific HRQOL tools, Pediatric Liver Transplant Quality of Life tool and the Pediatric Quality of Life Inventory 3.0 Transplant Module, have enabled enhanced representation of patient HRQOL, when used in conjugation with generic tools. Heterogeneity in study design and instruments prevented a quantitative, meta-analysis of the data. In conclusion, continued optimization of durable outcomes for this population mandates prioritization of research focusing on the gap of targeted intervention studies aimed at specific HRQOL subdomains and longitudinal studies to predict the trajectory of HRQOL over time.

Health-Related Quality of Life after Pediatric Liver Transplantation: A Qualitative Analysis of the Perspectives of Health Care Providers

With improved survival outcomes after pediatric liver transplantation (LT), health-related quality of life (HRQoL) is an important outcome metric. Understanding the elements contributing to HRQoL after LT in children would enable more targeted strategies towards optimizing best outcomes. This qualitative study aimed to explore health care providers (HCP) perceptions about HRQoL after pediatric LT. Thirteen experienced HCP participated in two focus group discussions. Data analysis via a thematic analysis approach revealed 4 major themes: "LT as a facilitator of better HRQoL," "coping and adapting to LT," "living with a transplanted liver," and "the family context." HCP identified elements that both enhance (improved physical health, peer relationship, and activities of daily living) and challenge (need for immunosuppression, transplant follow-up, and restrictions) the multidimensional domains of HRQoL. HCP perceived LT to be a stressful life-changing event for children and their families. Patients and their parents' ability to cope and adjust positively to LT was perceived as a key contributor to better HRQoL. HCP perspective highlights the importance of promoting psychosocial support and a family-centered care delivery model towards the overarching goal of optimizing durable outcomes.

Perioperative uncertainty in illness in patients with liver cancer: Influencing factors and nursing measures

AIM

To identify factors influencing perioperative uncertainty in illness in patients with liver cancer and evaluate the impact of systemic nursing intervention on quality of life and uncertainty in illness in patients with liver diseases before and after surgery.

METHODS

Two hundred patients with hepatocellular carcinoma undergoing surgical treatment at our hospital between January 2012 and January 2016 were reviewed retrospectively. They were divided into either an experimental group or a control group. The experimental group received systemic nursing intervention on the basis of routine care, and the control group received routine care only. Patients were administered the first questionnaire in the second day after admission, and the second questionnaire in the day before discharge. Mishel's Uncertainty in Illness Scale and the Chinese version of EORTC QLQ-C3 form were used to assess uncertainty in illness and quality of life, respectively.

RESULTS

The score of uncertainty in illness and scores of "ambiguity" and "complexity" were significantly influenced by education level, household income, source of medical expenses, and surgical method (P < 0.05), but were unrelated to age, sex, marital status, or place of residence (P > 0.05). After systematic nursing intervention, the score of uncertainty in illness and "ambiguity" score were decreased significantly compared with the control group (P < 0.05). After systematic nursing intervention, scores of general health situation, emotional function, role function and cognitive function in the experimental group were significantly increased compared with the control group (P < 0.05).

CONCLUSION

Systematic nursing intervention can improve uncertainty in illness and dimension scores and increase the quality of life of patients with liver cancer undergoing operation.

Health-related quality of life in long-term survivors of paediatric liver transplantation

BACKGROUND

Long-term survival after paediatric liver transplantation is now the rule rather than the exception. Improving long-term outcomes after transplantation must consider not only the quantity but also the quality of life years restored.

OBJECTIVES

To characterize health-related quality of life (HRQOL) of LT recipients ≥15 years after paediatric LT.

METHODS

Recipients of a paediatric LT performed before December 1996 in a single institution with continuous follow-up at either the paediatric or adult partner centre were identified. Patients with severe developmental or neurological impairment were excluded. HRQOL was assessed using the Pediatric Quality of Life Inventory 4.0, the Medical Outcomes Study Short Form-36 version 2 and the Pediatric Liver Transplant Quality of Life Tool.

RESULTS

A total of 27 (67% male) subjects (mean age 24.3±6.7 years [median 23.2 years; range 16.6 to 40.3 years]) participated. The median age at transplant was 1.7 years (range 0.5 to 17.0 years). Seven (26%) participants underwent retransplantation. Seventeen (63%) participants were engaged in full-time work/study. Mean Short Form-36 version 2 scores included physical (49.6±11.1) and mental (45.3±12.5) subscale scores. The mean score for the disease-specific quality of life tool for paediatric liver transplant recipients (the Pediatric Liver Transplant Quality of Life Tool) was 64.70±15.2. The physical health of the young adults strongly correlated with level of involvement in work/study (r=0.803; P<0.05).

CONCLUSIONS

The self-reported HRQOL of participants <18 years of age was comparable with a standardized healthy population. In contrast, participants between 18 and 25 years of age had HRQOL scores that were more similar to a group with chronic illness. Participants engaged in full-time work/study experienced enhanced physical health.

Achievement of developmental milestones in young adults after liver transplantation in childhood

Little is known about the achievement of developmental milestones (i.e., COL) after pediatric liver transplantation. The aim of this study was to examine the COL of young adults who underwent a liver transplantation during childhood and to compare it to healthy peers. Furthermore, we studied factors possibly related to their COL. COL was assessed using the CLQ, which assesses the achievement of developmental milestones (autonomy, psychosexual, social, and antisocial development) and risk behavior (substance abuse and gambling). Sociodemographic characteristics and clinical data were collected using the prospective institutional liver transplantation database. A total of 39 young adults who underwent a liver transplantation at the UMCG in their childhood completed the CLQ. They achieved fewer milestones with regard to autonomy, psychosexual, and social development compared to healthy peers, and they reported less risk behavior. Neither age at the time of study nor age at the time of transplantation was significantly correlated with any of the COL subscales. Young adults show delay in reaching developmental milestones in every dimension after a liver transplantation during their childhood.
