Non-adherence in pediatric liver transplant recipients--an assessment of risk factors and natural history

A consensus-based framework for the psychosocial evaluation of pediatric candidates for cardiothoracic transplant and ventricular assist devices

The psychosocial evaluation plays an essential role in the multidisciplinary assessment of pediatric patients for thoracic organ transplantation or ventricular assist device (VAD) placement. However, there is considerable practice variation with regard to the content and process of the evaluation, with no known recent published guidelines. Furthermore, the pediatric evaluation necessarily differs from the adult evaluation in a number of substantive ways, including caregiver roles and decision-making. A writing committee of 25 multidisciplinary experts in pediatric cardiothoracic transplantation/VAD was established, who conducted a comprehensive literature review which resulted in the development of this consensus-based framework. This framework, which is a collaborative effort of the International Society for Heart and Lung Transplantation (ISHLT), the International Pediatric Transplant Association (IPTA), the Pediatric Heart Transplant Society (PHTS), the Advancing Cardiac Therapies Improving Outcomes Network (ACTION), and Transplant Families, represents the first known framework specific to both the content and process of the psychosocial evaluation for pediatric cardiothoracic transplantation/VAD. Attention was paid to relevant ethical, cultural and health equity considerations inherent in the pediatric evaluation process. Rather than provide a proscriptive evaluation process, the goal was to create a flexible framework to encourage consistency across centers, while also acknowledging the complexities inherent in evaluating children and their families for cardiothoracic transplant and VAD.

International Society for Heart and Lung Transplantation Guidelines for the Evaluation and Care of Cardiac Transplant Candidates-2024

The "International Society for Heart and Lung Transplantation Guidelines for the Evaluation and Care of Cardiac Transplant Candidates-2024" updates and replaces the "Listing Criteria for Heart Transplantation: International Society for Heart and Lung Transplantation Guidelines for the Care of Cardiac Transplant Candidates-2006" and the "2016 International Society for Heart Lung Transplantation Listing Criteria for Heart Transplantation: A 10-year Update." The document aims to provide tools to help integrate the numerous variables involved in evaluating patients for transplantation, emphasizing updating the collaborative treatment while waiting for a transplant. There have been significant practice-changing developments in the care of heart transplant recipients since the publication of the International Society for Heart and Lung Transplantation (ISHLT) guidelines in 2006 and the 10-year update in 2016. The changes pertain to 3 aspects of heart transplantation: (1) patient selection criteria, (2) care of selected patient populations, and (3) durable mechanical support. To address these issues, 3 task forces were assembled. Each task force was cochaired by a pediatric heart transplant physician with the specific mandate to highlight issues unique to the pediatric heart transplant population and ensure their adequate representation. This guideline was harmonized with other ISHLT guidelines published through November 2023. The 2024 ISHLT guidelines for the evaluation and care of cardiac transplant candidates provide recommendations based on contemporary scientific evidence and patient management flow diagrams. The American College of Cardiology and American Heart Association modular knowledge chunk format has been implemented, allowing guideline information to be grouped into discrete packages (or modules) of information on a disease-specific topic or management issue. Aiming to improve the quality of care for heart transplant candidates, the recommendations present an evidence-based approach.

Post-traumatic growth among pediatric transplant recipients and their caregivers: A scoping review

BACKGROUND

Pediatric transplantation can be a stressful process for patients and caregivers. Some individuals may experience post-traumatic stress symptoms (PTSS) and post-traumatic growth (PTG) as a result. Although post-traumatic stress disorder (PTSD) has been well-studied in this population, the purpose of the present scoping review is to provide a first synthesis of the existing literature on PTG in pediatric transplant populations.

METHODS

We conducted a literature search of PsycINFO and Scopus in May 2023. Eligible articles must have included a sample of solid organ transplant (SOT) or stem cell transplant (SCT) recipients under age 18, siblings of recipients, or caregivers; and must have examined PTG.

RESULTS

Twenty-three studies were identified, and nine studies met inclusion criteria and were included in the review (n = 5 cross sectional; n = 4 qualitative). Cross-sectional studies examined demographic, mental health, and medical correlates of PTG in children and caregivers. PTG was correlated with PTSS among caregivers. Qualitative studies identified themes along each of the five factors of PTG.

CONCLUSION

Findings overwhelmingly focused on caregiver PTG. Qualitative study findings align with the theoretical model of PTG. Additional research is needed to investigate PTG in siblings of children with a transplant and associations between PTG and medication adherence. This scoping review provides insight into positive change processes following a transplant among children and their caregivers.

Biliary Atresia in Adolescence and Adult Life: Medical, Surgical and Psychological Aspects

Prior to 1955, when Morio Kasai first performed the hepatic portoenterostomy procedure which now bears his name, Biliary atresia (BA) was a uniformly fatal disease. Both the Kasai procedure and liver transplantation have markedly improved the outlook for infants with this condition. Although long-term survival with native liver occurs in the minority, survival rates post liver transplantation are high. Most young people born with BA will now survive into adulthood but their ongoing requirements for health care will necessitate their transition from a family-centred paediatric service to a patient-centred adult service. Despite a rapid growth in transition services over recent years and progress in transitional care, transition from paediatric to adult services is still a risk for poor clinical and psychosocial outcomes and increased health care costs. Adult hepatologists should be aware of the clinical management and complications of biliary atresia and the long-term consequences of liver transplantation in childhood. Survivors of childhood illness require a different approach to that for young adults presenting after 18 years of age with careful consideration of their emotional, social, and sexual health. They need to understand the risks of non-adherence, both for clinic appointments and medication, as well as the implications for graft loss. Developing adequate transitional care for these young people is based on effective collaboration at the paediatric-adult interface and is a major challenge for paediatric and adult providers alike in the 21st century. This entails education for patients and adult physicians in order to familiarise them with the long-term complications, in particular for those surviving with their native liver and the timing of consideration of liver transplantation if required. This article focusses on the outcome for children with biliary atresia who survive into adolescence and adult life with considerations on their current management and prognosis.

Acceptability and utility of a virtual pediatric transplant peer mentoring program: A mixed-methods analysis of a novel quality improvement program

BACKGROUND

Adolescent transplant patients are at increased risk for graft loss at a period when they also suffer from illness-related social isolation, which has been exacerbated by the COVID-19 pandemic. The Peer Mentoring Program (PMP), developed in 2018, was adapted to a virtual format in 2020 due to COVID-19. Our objective is to evaluate the acceptability, utility, and potential impact of the in-person and virtual versions of the PMP on participants.

METHODS

We performed convergent mixed-methods analysis of the experiences of patients participating in the PMP for quality improvement purposes.

RESULTS

Surveys and focus group invitations were sent to 18 current program participants, with 17 patients responding to the survey and 13 patients participating in focus groups. In this study, 82% were satisfied and 88% would recommend PMP; 76% identified other PMP members as people they would like to keep in touch with. Qualitative analysis revealed three themes: (1) a supportive community of peers, (2) reduced isolation, and (3) receiving accurate information from providers.

CONCLUSIONS

There is a prominent need for greater peer support among adolescent transplant patients transitioning to adulthood, especially with the increased isolation associated with COVID-19. The virtual adaptation could be an important, permanent supplement to in-person events.

Randomized pilot trial of praise text messages to improve medication adherence among adolescents and young adults with liver transplants

BACKGROUND

AYA who have undergone liver transplantations often struggle to adhere to their post-transplant immunosuppressant medications, which can lead to serious health complications. The objective of this pilot study is to examine the acceptability and feasibility of a brief mobile health (mHealth) intervention and its impact on medication adherence among AYA liver transplant recipients.

METHODS

Thirty-five AYAs (13-21 years old) were randomized to either (1) receive praise text messages whenever laboratory results indicated immunosuppressant medications within the expected range or (2) usual care. Motivation for adherence and adherence were assessed via self-report, and a MLVI was calculated based on values abstracted from the electronic health record.

RESULTS

Multilevel, multivariate models showed significant associations between group assignment and some self-reported motivation and adherence outcomes but not MLVI. Specifically, AYA receiving the praise text messages were significantly more likely to report taking their prescribed doses (OR = 2.49, p = .03), taking their medicine according to the directions (OR = 2.39, p = .04), and being highly confident in taking their medication (OR = 2.46, p = .04), compared with the usual services group. Qualitative responses indicated praise texts were mostly helpful but could be improved.

CONCLUSIONS

The results suggest texting patients about positive health indicators was acceptable and, with refinement, might promote AYA illness self-management.

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 text messaging intervention and quality of life in adolescents with solid organ transplants

BACKGROUND

Facilitating communication between adolescents and HCP outside of appointments may enhance patient experience and outcomes. The purpose of this study was to determine whether SMS enhances the healthcare experience, QoL, and medication adherence in adolescent SOT patients.

METHODS

This was a prospective observational study of an SMS platform (WelTel Inc) for SOT patients aged 12-19 years. QoL was assessed before and after using the PedsQL™ Transplant Module. Medication adherence was assessed with the frequency of therapeutic tacrolimus levels and variation based on control chart analysis. Patient experience and engagement was evaluated with surveys, response rate to messages, and number of clinical conversations (>2 messages).

RESULTS

Twenty-three patients were included (median age 15.7 years (IQR 13.6-17.1)). Median intervention duration was 13.5 months (range 4.0-16.7 months). There was a 68% response rate (742/1095) with 375 clinical conversations. The majority of patients reported the intervention provided a positive outlook on their health (17/23), was useful (18/23), and improved their connection to HCPs (17/23). Following the intervention, there was no significant difference in the median scaled QoL scores (pre-intervention: 81 (IQR 76.5-93.3), post-intervention: 78 (IQR 76-93); p = .37), mean percentage of therapeutic tacrolimus levels (pre-intervention: 52 ± 25%, post-intervention: 65 ± 17%; p = .07), or variation on control chart analysis of tacrolimus levels.

CONCLUSIONS

The WelTel messaging platform provided supplemental clinical care for a group of adolescent SOT patients that enhanced their healthcare experience. Patient QoL and adherence were unchanged following the intervention and remained at a high level.

Effectiveness of mobile health-based self-management application for posttransplant cares: A systematic review

BACKGROUND AND AIMS

Patients after transplantation need medical management for the rest of their lives, and self-management seems to lead to greater adherence to medical standards, improve early physical changes, and increase patient empowerment. The main objective of this article is to systematic review of the consideration to mobile health applications (m-Health apps) used in transplantation.

METHODS

A systematic search was conducted MEDLINE (through PubMed), Web of Science, Scopus, and Science Direct from inception to November 2020. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement was used in this study. Comprehensive research was carried out using a combination of keywords and MeSH terms associated with m-Health, empowerment, self-management, and transplantation. Two independent reviewers screened titles and abstracts, assessed full-text articles, and extracted data from articles that met inclusion criteria. Eligible studies were original research articles that included posttransplant care and mobile phone-based applications to support self-management and self-care. Also, thesis, book chapters, letters to editors, short briefs, reports, technical reports, book reviews, systematic reviews, or meta-analysis were excluded.

RESULTS

We divided all the reviewed articles into four categories, self-management (medication adherence, adherence to medical regimen, and remote monitoring), evaluation, interaction, and interface; 37.5% of the studies were focused on lung transplantation. In 56.25% of the studies, medication adherence was considered because one of the main reasons for the rejection and graft loss is stated medication nonadherence. Also, 62.5% of the studies demonstrated that the use of m-health improved medication adherence and self-management in transplantation.

CONCLUSIONS

The use of m-Health apps interventions to self-management after transplantation has shown promising feasibility and acceptability, and there is modest evidence to support the efficacy of these interventions. We found that m-Health solutions can help the patient in self-management in many ways after transplantation.

Examining the association of medical complications and posttraumatic stress symptoms in pediatric solid organ transplant patients and their caregivers

BACKGROUND

Post-traumatic stress symptoms (PTSS) have been reported by pediatric solid organ transplant (SOT) patients and their caregivers well after transplantation. This study examined the relationship between PTSS, medication adherence, and medical complications in SOT patients and their caregivers. A secondary aim examined the association between patient and caregiver-reported PTSS.

METHODS

Pediatric SOT patients (N = 69) and caregivers (N = 73) reported on PTSS by completing the Child PTSD Symptom Scale (patients 8-17 years) or the Impact of Events Scale-Revised (patients 18 years and older and caregivers). Patient medication adherence was assessed using the Medication Level Variability Index (MLVI). Patients were dichotomized as experiencing a post-transplant medical complication (ie, transplant-related hospital admission prior to the year completing measures of PTSS) or no complications.

RESULTS

Medication adherence was not significantly associated with patient or caregiver PTSS. A moderate effect size was found for elevated young adult and caregiver PTSS and the presence of a medical complication. Generally, the association between self-reported patient and caregiver PTSS was low.

CONCLUSIONS

The presence of elevated PTSS in young adult patients may be partially explained by the presence of proximal medical complications and more so by comorbid psychiatric diagnoses in child and adolescent patients (based on exploratory analyses). Caregivers of patients with medical complications within the past year reported higher levels of PTSS. Overall, transplantation and its associated impact on PTSS may be unique experience for patients versus caregivers. Qualitative research may further elucidate these experiences and inform future clinical interventions.

Understanding Substance use Policies and Associated Ethical Concerns: A survey of Pediatric Transplant Centers

Psychosocial risk factors, such as substance use, have been linked to poor post-transplant outcomes for solid organ transplant patients, including poor medication adherence, increased risk for rejection, and even graft failure. Despite universal consensus that substance use is an increasing problem among youth, many pediatric transplant centers do not have policies in place to address substance use and no universal guidelines exist regarding assessment during the pre-transplant evaluation in this population. An online survey was administered via REDCap™ and directed toward medical leaders (ie, medical and surgical directors) of national heart, kidney, and liver transplant centers. Questions examined the following: perspectives on the need for a universal transplant center policy on pediatric substance use, abuse, and dependence; timing and frequency of evaluation for substance use; specific substances which would elicit respondents' concerns; and ethical concerns surrounding substance use. Data were analyzed using descriptive statistics. Data were collected from 52 respondents from 38 transplant centers, with the majority (n = 40; 77%) reporting no substance use policy in place for pediatric transplant patients. However, many endorsed concerns if a pediatric patient was found to be using specific substances. Our findings further highlight the need for a universal substance use policy across pediatric solid organ transplant centers. The results from the distributed survey will help to provide guidelines and best practices when establishing a universal policy for substance use.

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.

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.

The impact of psychiatric disorders on outcomes following heart transplantation in children

Psychiatric disorders are common in pediatric HTx recipients. However, the impact of psychiatric comorbidities on patient outcomes is unknown. We aimed to assess the impact of disorders of adjustment, depression, and anxiety on HTx outcomes in children; hypothesizing that the presence of psychiatric disorders during or preceding HTx would negatively impact outcomes. All pediatric HTx recipients ≥8 years of age who survived to hospital discharge were identified from a novel linkage between the PHIS and SRTR databases (2002-2016). Psychiatric disorders were identified using ICD codes during or preceding the HTx admission. Post-transplant graft survival, freedom from readmission, and freedom from rejection were analyzed using the Kaplan-Meier method. Multivariable Cox proportional hazard models were used to adjust for covariates. A total of 1192 patients were included, of which 133 (11.2%) had depression, 197 (16.5%) had anxiety, and 218 (18.3%) had adjustment disorders. The presence of depression was independently associated with higher rates of readmission (60.9% vs 54.1% at 6 months) (AHR 1.63, 95% CI 1.22-2.18, P = .001) and inferior graft survival (70.2% vs 83.4% at 5 years) (AHR 1.62, 95% CI 1.14-2.3, P = .007). Anxiety was independently associated with higher rates of readmission (60.4% vs 53.9% at 6 months) (AHR 1.46, 95% CI 1.09-1.94, P = .01). Anxiety and depression in the pretransplant period are independently associated with outcomes following HTx in children. Evaluation and management of psychiatric comorbidities represents an important component of care in this vulnerable population.

Non-adherence and transition clinics

The majority of children who undergo liver transplantation now survive into adulthood and their requirement for life-long follow-up means that they will need to transition from paediatric to adult services. Poor transition is a risk factor for poor clinical and psychosocial outcomes and one of the barriers to effective transition is vulnerability to risk-taking behaviours, and specifically non-adherence. This chapter focuses on practical considerations for transitioning young people from paediatric to adult services, with a particular focus on the risk factors associated with non-adherence and examples of interventions for managing it.

Toward a better understanding: An exploration of provider perceptions in pediatric hematopoietic stem cell transplant adherence

Pediatric HSCT patients endure complicated treatment regimens, lifestyle modifications, and a lifetime of long-term follow-up. Treatment adherence in this population is understudied and prevalence unknown. Providers (physicians and advanced practice nurses) in this study completed an online-structured questionnaire about definition, assessment, and perceived rates of adherence. Researchers' extracted 187 statements from participants' responses. The majority (n = 12, 71%) of providers reported adherence as a primary concern in outpatient HSCT. The major concern for providers was the potential of non-adherence to negatively affect outcomes. Providers also shared clinical examples of non-adherence. This study contributes to a better understanding of providers' perceptions of adherence within pediatric HSCT. Additional research is needed to describe, define, and improve adherence in pediatric HSCT to ultimately improve outcomes and quality of life for this vulnerable population.

Relationship between spiritual health and hope by dietary adherence in haemodialysis patients in 2018

Aim

The present study aimed to determine the relationship between spiritual well-being and hope through adherence to diet in haemodialysis patients referred to the dialysis centre.

Design

This research was a cross-sectional study of a descriptive-analytical type conducted on 120 patients undergoing haemodialysis in a haemodialysis centre of a hospital affiliated to Dezful University of Medical Sciences using the census method.

Method

The data were collected using a questionnaire and through the laboratory information included in the patient's records. The data collection tools were a demographic information questionnaire, the Ellison and Paloutzian spiritual well-being scale (SWBS), the Hope-Herth questionnaire and the objective laboratory criteria (phosphorus, potassium). This included the weight difference between the two dialysis sessions from the record to examine the adherence to the diet.

Results

The results indicate there to be a significant relationship between hope and spiritual well-being with the objective criteria of the adherence to the diet in dialysis patients (p = .001).

Digital medicine program with pediatric solid organ transplant patients: Perceived benefits and challenges

Given the complexity of the pediatric post-transplant medication regimen and known medication adherence difficulties within the solid organ transplant population, interventions to improve adherence continue to be explored and fine-tuned. Advances in technology have led to the development of new programs aimed at improving medication adherence and the overall care of transplant patients. This manuscript describes implementation of a DMP where transplant patients' medications were co-encapsulated with ingestible sensors, and adherence was monitored via a patient mobile application and a provider portal. The benefits and challenges of the DMP as reported by patients, caregivers, and medical providers are explored in this manuscript. Participant feedback regarding best practices highlighted these benefits: ease of use/intuitive technology, sense of improved communication with medical team, increased knowledge and motivation around treatment regimen, and positive self-reports of medication adherence. Challenges included reluctance to participate (n = 43, 54.43% of patients approached declined participation) and patch wearability difficulties reported by participants (n = 20; 68.97%). Other notable challenges included the following: limited drug profile compatibility with the DMP technology and concerns about privacy and electronic data sharing for patients who chose not to participate. DMP implementation highlighted how technological advances offer novel methods to assess adherence, enhance medical decision-making, and can potentially improve clinical outcomes. Although numerous benefits of the program were recognized by participants, challenges were identified and the DMP technology and medication panel continues to be refined; further investigation of such programs continues to be warranted.

Preparing for transition: The effects of a structured transition program on adolescent heart transplant patients' adherence and transplant knowledge

Transition to adult health care has become a mainstream focus in pediatric health care as a higher percentage of patients are surviving into adulthood. This study investigated the success of a structured educational transition program in improving pediatric heart transplant patients' overall medical knowledge, medication adherence, readiness to transition, as well as parental perceptions of their child's readiness to transition to aid in the successful transition to an adult heart transplant program. Patients underwent a structured transition program over 2 years that included a total of seven 2-hour educational sessions hosted quarterly. This study comprised of a retrospective review of 12 heart transplant patients between the ages of 16-22 years. Test results indicated a statistically significant increase in overall medical knowledge scores from presession assessment compared to post-session assessment. Participants remained confident in their ability to transition throughout the program. Further, a statistically significant decrease in participant non-adherence was observed, as percentage of calcineurin inhibitor levels determined to be out of range decreased over the course of the program. Results suggest that a structured transition program is effective in improving overall patient medical knowledge in relation to their heart transplant and enhancing patient medication adherence. To effectively facilitate transition, pediatric providers, caregivers, and patients must communicate to provide a purposeful planned transition experience from pediatric to adult health care.

Healthcare transition in pediatric liver transplantation: The perspectives of pediatric and adult healthcare professionals

INTRODUCTION

Transition from pediatric to adult services of young people with a liver transplant is an important priority due to increasing numbers of young people surviving into adulthood. There is increased incidence of graft loss and non-adherence following transfer to adult services. Although studies have considered the views and perceptions of young people who have undergone liver transplantation and their parents about transition, there is currently no qualitative research with healthcare professionals working in the field of liver transplantation. The aim of this study was to elicit the views of this group of stakeholders about barriers and facilitators of an effective transition process.

METHODS

Semi-structured interviews were carried out with 11 HCPs from pediatric and adult liver transplant programs and from a range of professional backgrounds. Interviews were transcribed verbatim and analyzed using thematic analysis.

RESULTS

Four themes were identified: "non-adherence and psychosocial issues," "need for better psychological support," "the role of parents," and "the emotional impact of transition on healthcare professionals." Within these themes, professionals described factors which hindered or promoted an effective transition process.

CONCLUSIONS

Screening tools which address psychological and social aspects of the lives of young people should be used in routine practice to identify patients requiring psychosocial support and to identify those at risk of non-adherence. All staff involved with transition should be trained in the use of psychosocial screening strategies. The development of a formal referral pathway so that young people can access psychological support in adult services is recommended.

Medication self-management and the quality of discharge education among parents of children with epilepsy

INTRODUCTION

Medication self-management is critical among children with epilepsy. In the present study, we aimed to investigate the perceptions regarding the quality of discharge education among parents of children with epilepsy. In addition, we assessed the impact of their perceptions on medication self-management. The quality of discharge education was assessed in two parts: content and delivery. The quality of delivery was defined as the manner in which nurses teach the content regarding hospital discharge.

METHODS

Forty-seven parents of children with epilepsy completed the questionnaires regarding demographics, the quality of discharge education, and medication self-management (the Quality of Discharge Teaching Scale and the Pediatric Epilepsy Medication Self-Management Questionnaire).

RESULTS

Parent-reported quality of discharge education was positively correlated with medication self-management (r = 0.305; p = .037). Parent-reported quality of delivery, but not the amount of content, was positively correlated with medication self-management (r = 0.347; p = .017).

CONCLUSIONS

These data suggest that efforts to improve medication self-management among children with epilepsy should include strategies to develop teaching skills among nurses delivering the discharge education.

Adherence to medical regimen after pediatric liver transplantation: a systematic review and meta-analysis

PURPOSE

Adherence to the medical regimen after pediatric liver transplantation is crucial for good clinical outcomes. However, the existing literature provides inconsistent evidence regarding the prevalence of and risk factors for nonadherence to the medical regimen after pediatric liver transplantation. This study aimed to investigate such nonadherence after pediatric liver transplantation and risk factors associated with this nonadherence using findings of reported studies.

METHODS

The electronic databases of Excerpta Medica, Ovid Technologies, PubMed and WanFang Data were searched using the keywords "adherence", "liver transplant" and "paediatric". Additionally, relevant references cited in related studies were used to obtain original articles. Using 22 original articles, data regarding nonadherence to the medical regimen after pediatric liver transplantation were quantitatively combined, and risk factors associated with nonadherence were qualitatively identified. Average rates of nonadherence in four areas of medical regimens were calculated. The heterogeneity of the included original articles was also analyzed. When I ²>50 and P<0.05, a random effects model was used; otherwise, a fixed effects model was used. Moreover, Egger's and Begg's tests were used to evaluate publication bias, if any, and original articles with P>0.05 were considered to have no publication bias.

RESULTS

The clinical attendance nonadherence rate was 45% (95% confidence interval [CI]: 39-51), global nonadherence rate was 17% (95% CI: 13-21) and immunosuppression non-adherence rates were 39% (95% CI: 26-52) and 34% (95% CI: 30-39) for cyclosporine and tacrolimus, respectively. Risk factors included older age of the pediatric patient, low family cohesion, poor social functioning, poor mental health and single-parent family.

CONCLUSIONS

The nonadherence rate in pediatric liver transplantation is high. Therefore, intervention on the basis of risk factors, such as mental health and family function, may be necessary. Moreover, a standard technique for assessing nonadherence to the medical regimen after pediatric liver transplantation, comprising as many dimensions as possible, is required in order to be more objective and comprehensive when assessing nonadherence.

Psychosocial predictors of medication non-adherence in pediatric organ transplantation: A systematic review

Adherence to immunosuppressant medication is critical to health and quality-of-life outcomes for children who have received a solid organ transplant. Research on the psychological and social predictors of medication adherence is essential to the advancement of pretransplant assessments and transplant psychosocial services. Despite the importance of identifying risk factors, the literature remains limited regarding psychosocial predictors of non-adherence. A systematic search was conducted to identify studies of the psychosocial predictors of post-transplant medication non-adherence in pediatric solid organ transplantation. From 1363 studies identified in searches of empirical literature, a final sample consisted of 54 publications representing 49 unique studies. Findings regarding psychosocial predictors were inconsistent with non-adherence associated largely with adolescence, racial/ethnic minority status, and presence of mental health issues. Familial predictors of non-adherence problems included single-parent households, lower socioeconomic status, lower family cohesion, presence of family conflict, and poor family communication. Several studies reported an association between non-adherence and social pressures (eg, peer social interaction, wanting to feel normal) among adolescent transplant recipients. While significant methodological and substantive gaps remain in this body of knowledge, this review synthesizes current evidence for assessment for transplant clinicians and researchers.

Pediatric Liver Transplantation: Unique Concerns for the Critical Care Team

Liver transplantation originated in children more than 50 years ago, and these youngest patients, while comprising the minority of liver transplant recipients nationwide, can have some of the best and most rewarding outcomes. The indications for liver transplantation in children are generally more diverse than those seen in adult patients. This diversity in underlying cause of disease brings with it increased complexity for all who care for these patients. Children, still being completely dependent on others for survival, also require a care team that is able and ready to work with parents and family in addition to the patient at the center of the process. In this review, we aim to discuss diagnoses of particular uniqueness or importance to pediatric liver transplantation. We also discuss the evaluation of a pediatric patient for liver transplant, the system for allocating them a new liver, and also touch on postoperative concerns that are unique to the pediatric population.

Development and field testing of Teen Pocket PATH(®), a mobile health application to improve medication adherence in adolescent solid organ recipients

Applying principles of user-centered design, we iteratively developed and tested the prototype of TPP, an mHealth application to promote medication adherence and enhance communication about medication management between adolescents and primary caregivers. A purposive sample of seven adolescent solid organ transplant recipients who were ≥ one yr post-transplant and their primary caregivers participated. Participants completed up to three face-to-face laboratory usability sessions, a 6-week field test, and a debriefing session. Primary caregivers participated in an additional usability telephone session. Participants completed usability and satisfaction measures. Sample included liver (n = 4), heart (n = 2), and lung (n = 1) recipients aged 11-18 yr (57% were female, 86% were Caucasian), and nine primary caregivers aged 42-61 yr (88.9% were parents, 88% were female, 88% were Caucasian). Ninety percent of the adolescents endorsed the graphs or logs of missed/late medication dosing as useful and 100% endorsed the remaining features (e.g., medication list, dose time reminders/warnings) as useful. All adolescents expressed interest in using TPP for monitoring medications and satisfaction with the automatic messaging between adolescent and caregiver versions of the application. Adolescents unanimously found TPP easy to use. TPP shows promise as an mHealth adherence tool.

Monitoring drug adherence

TOPIC

Medication nonadherence is prevalent in transplant recipients and is a major reason for graft loss. The present review discusses the measurement of adherence in transplant recipients and strategies to improve adherence. SOURCES REVIEWED: Since adherence research is not confined to transplant recipients, our literature review included studies relevant to transplant recipients as well as adherence to medical recommendations more generally. We reviewed manuscripts in the English language indexed in PubMed Central, as well as ancillary sources of information such as textbook chapters that are not indexed.

CONCLUSION

There is no consensus in the literature about an optimal way to monitor adherence, nor is there agreement about a preferred management strategy. Until definitive studies demonstrate the effectiveness of intervention strategies, knowledge of the monitoring as well as intervention methods that are described in this review is expected to give practitioners the initial tools to deal with nonadherence as an important aspect of patient care.

Fingerprints of transplant tolerance suggest opportunities for immunosuppression minimization

HLA incompatible organ transplant tolerance is the holy grail of transplantation. Stable engraftment of an HLA mismatched allograft and life-long tolerance induction, though feasible in highly selected cohorts with depletional protocols, is not ready for generalized application to the entire transplant recipient pool. It has thus been important to harness biomarkers that can uncover mechanisms and tools for monitoring HLA mismatched recipients that develop a state of operational tolerance, during accidental immunosuppression withdrawal secondary to problems of over-immunosuppression (infection or malignancy) or toxicity (mostly cosmetic or cardiovascular). A restricted and unpredictable group of patients can demonstrate a clinical state of operational tolerance, manifested by state of stable graft function of a graft with HLA mismatches between recipient and donor, intact immune responses to third party antigens and no measurable immunosuppression. These patients have served as the basis for the discovery of clinically correlative biomarkers, in distal biofluids (mainly blood), that can define the existing state of operational clinical tolerance. Operationally tolerant patients are rare, as withdrawal of immunosuppression most often results in rejection and graft loss. Nevertheless, operationally tolerant kidney, liver and heart allograft recipients have been reported. The presence of similar biomarker signature profiles in HLA mismatched transplant recipients on immunosuppression, suggests the feasibility of utilizing these biomarkers for educated immunosuppression minimization with a view to retaining immunological quiescence, while reducing the maintenance immunosuppression burden to a "safe" alloimmune threshold. Though clinical operational tolerance is rare, as immunosuppression cessation most often results in increased alloimmunity and rejection, the biomarker profile studies that have harnessed whole genome profiling suggest that the frequency of this state may be ~8% in kidney allograft recipients, and even more frequent in pediatric recipients and in liver transplantation: 25% in adult liver allograft recipients and ~60% in pediatric liver allograft recipients. In this review we discuss putative molecular mechanisms, cellular players and correlative biomarkers that have been developed through clinically associative studies of tolerant and non-tolerant patients. Through mechanisms of carefully constructed and monitored randomized, prospective clinical trials, the transplant community stands at the cusp of improved quality of recipient life through educated immunosuppression minimization.

The Telehealth Enhancement of Adherence to Medication (TEAM) in pediatric IBD trial: Design and methodology

Medication nonadherence is a significant health care issue requiring regular behavioral treatment. Lack of sufficient health care resources and patient/family time commitment for weekly treatment are primary barriers to receiving appropriate self-management support. We describe the methodology of the Telehealth Enhancement of Adherence to Medication (TEAM) trial for medication nonadherence in pediatric inflammatory bowel disease (IBD). For this trial, participants 11-18 years of age will be recruited from seven pediatric hospitals and will complete an initial 4-week run in to assess adherence to a daily medication. Those who take less than 90% of their prescribed medication will be randomized. A total of 194 patients with IBD will be randomized to either a telehealth behavioral treatment (TBT) arm or education only (EO) arm. All treatments will be delivered via telehealth video conferencing. The patients will be assessed at baseline, post-treatment, 3, 6, and 12 months. We anticipate that participants in the TBT arm will demonstrate a statistically significant improvement at post-treatment and 3-, 6-, and 12-month follow-up compared to participants in the EO arm for both medication adherence and secondary outcomes (i.e., disease severity, patient quality of life, and health care utilization). If efficacious, the TEAM intervention could be disseminated broadly and reduce health care access barriers so that the patients could receive much needed self-management intervention.

Post-transplant adjustment--the later years

As survival rates for pediatric solid organ transplantation have continued to improve, researchers and healthcare providers have increasingly focused on understanding and enhancing the HRQOL and psychosocial functioning of their patients. This manuscript reviews the psychosocial functioning of pediatric transplant recipients during the "later years," defined as more than three yr post-transplant, and focuses on the day-to-day impact of living with a transplant after the immediate period of adjustment and early years after surgery. Key topics reviewed include HRQOL, cognitive functioning, impact on the family, regimen adherence, and transition of responsibility for self-management tasks. Overall, pediatric transplant recipients evidence impairment in HRQOL, neuropsychological outcomes, and family functioning as compared to non-transplant recipients. However, the degree of impairment is influenced by a variety of factors including, disease severity, age, solid organ type, and study methodologies. Studies are limited by small samples, cross-sectional design, and the lack of universal assessment battery to allow for comparisons across solid organ populations. Areas for future research are discussed.

The adolescent liver transplant patient

The rapid development of new diagnostic tests and improved therapy, especially the success of liver transplantation, has changed the outcome for children with liver disease, many of whom survive into adolescence without liver transplantation. The indications for transplantation in adolescence are similar to pediatric indications and reflect the medical advances made in this specialty that allow later transplantation. These young people need a different approach to management that involves consideration of their physical and psychological stage of development. A focused approach to their eventual transition to adult care is essential for long-term survival and quality of life.

A cross-sectional survey of childhood trauma and compliance with general health care among adult primary care outpatients

OBJECTIVE

Beyond the examination of medication compliance among individuals with substance abuse or human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), few studies have examined relationships between childhood trauma and health care compliance in adulthood-the focus of the present study.

METHOD

Using a cross-sectional approach and a self-report survey methodology, we examined 5 types of childhood trauma (ie, witnessing violence, physical neglect, emotional abuse, physical abuse, sexual abuse) in relationship to 4 measures of general health care compliance (ie, self-rated general conscientiousness with medical treatment; 5 items pertaining to general health care compliance such as scheduling regular dental checkups, timely arrival for doctor's appointments, and timely completion of laboratory work; 2 medication compliance items; and the Medical Outcomes Study general adherence score) among a sample of adult primary care outpatients (N = 272). Data were collected in March 2014.

RESULTS

According to findings, some health care adherence variables demonstrated relationships with the summed childhood trauma score, whereas others did not. It could be interpreted that the more subjective health care compliance variables (eg, self-rated conscientiousness with regard to medical treatment) demonstrated no relationship with a summed childhood trauma score, whereas the more objective health care compliance variables (eg, frequency of regular dental checkups, ability to remember to take all medications, Medical Outcomes Study general adherence score) did demonstrate statistically significant relationships with a summed childhood trauma score (most at P < .01).

CONCLUSIONS

Patients with histories of childhood trauma demonstrate some deficits with health care compliance in comparison to those without childhood trauma. One interpretation is that the mistreated appear to believe that they are fairly compliant with health care treatment, but objective variables appear to suggest otherwise.

Adolescent transplant recipients as peer mentors: a program to improve self-management and health-related quality of life

The purpose of this study was to examine the safety, feasibility, acceptability, and preliminary efficacy of a cross-age peer mentoring program created to improve adherence and psychosocial outcomes for pediatric liver transplant recipients. Twenty-two participants were assigned to a "mentor now" or "mentor later" waitlist control group. Tacrolimus SD, a validated measure of adherence, was assessed for six months pre- and post-intervention for both groups. Self-report measures of self-management and HRQOL were completed at recruitment and three months after training. Participant report indicated the acceptability of the intervention. Clinically significant improvement in adherence was detected. No significant changes on the psychosocial outcome measures at follow-up were observed. This study demonstrated that an outpatient-based mentoring program is a safe, feasible, and acceptable option to incorporate within a pediatric liver transplant program with potential for promising application in other transplantation populations as well. These results also suggest that the program may have been associated with meaningful improvement in adherence, although further evaluation is warranted.

Impact of medication non-adherence on survival after pediatric heart transplantation in the U.S.A

BACKGROUND

Medication non-adherence (NA) can result in life-threatening illness in children after solid-organ transplantation. Little is known about the incidence, risk factors and outcomes of NA in large numbers of pediatric heart transplant (HT) recipients.

METHODS

Organ Procurement Transplant Network (OPTN) data were used to identify all children <18 years of age in the U.S.A. who underwent HT from October 1999 to January 2007. Cox proportional hazards analysis was used to identify risk factors for NA and the effect on graft survival.

RESULTS

Of 2,070 pediatric heart transplants performed the median age at transplant was 6 years (interquartile range [IQR] 0 to 13 years); 40% had congenital heart disease (CHD), 7% were re-transplants, 42% were non-white and 43% had Medicaid insurance. Overall, 186 (9%) children had a report of NA at a median age of 15 years with more than two-thirds of NA episodes occurring after 12 years of age. Factors independently associated with NA were: adolescent age at transplant (hazard ratio [HR] 7.0, 95% confidence interval [CI] 4.1 to 12, compared with infants); black race (HR 2.3, 95% CI 1.7 to 3.3, compared with white); Medicaid insurance (HR 2.0, 95% CI 1.5 to 2.7, compared with non-Medicaid insurance); and ventilator or ventricular assist device (VAD) support at transplant. The risk of mortality conditional upon report of NA was 26% at 1 year and 33% at 2 years.

CONCLUSIONS

Medication NA is an important problem in pediatric HT recipients and is associated with high mortality. Adolescent age, black race, Medicaid insurance and invasive hemodynamic support at transplant were associated with NA, whereas time on the wait list and gender were not. Targeted interventions among at-risk populations may be warranted.

Complex traumatic stress in the pediatric medical setting

There has been a recent increase in research focusing on child complex traumatic stress following prolonged or repeated trauma. These traumatic stress reactions often affect many aspects of the child's functioning, including psychological, behavioral, and physical health. In addition, complex traumatic stress experienced by youth with serious medical conditions may influence health issues such as medical adherence, emotional adjustment to illness, and pain management. This article reviews and delineates the current state of the literature on the impact of complex traumatic stress in childhood on mental and physical health as well as on these pediatric health-related issues. To date, few empirical studies have directly addressed this association. Several features associated with complex traumatic stress, such as emotion regulation difficulties, disruptive behavior, and family conflict, have indirectly been demonstrated to interfere with pediatric adherence, medical coping, and pain management. This demonstrates the need for more focused research in this area.

Challenges in treating oppositional defiant disorder in a pediatric medical setting: a case study

The following case study is presented to highlight the importance of consistency in identifying and treating oppositional defiant disorder in a pediatric patient with a life-threatening medical illness. A pediatric transplant patient's oppositional behaviors are described, as well as the educational behavioral training program provided to the patient's caregivers and medical staff. As a result of the training, the patient engaged in less oppositional behavior, was more cooperative and pleasant with staff, and was more compliant with her treatment. Subjective reports from caregivers indicated that the training with its emphasis on consistency effectively reduced the patient's symptoms and enhanced the caregivers' ability to care for the patient.

Pediatric self-management: a framework for research, practice, and policy

Self-management of chronic pediatric conditions is a formidable challenge for patients, families, and clinicians, with research demonstrating a high prevalence of poor self-management and nonadherence across pediatric conditions. Nevertheless, effective self-management is necessary to maximize treatment efficacy and clinical outcomes and to reduce unnecessary health care utilization and costs. However, this complex behavior is poorly understood as a result of insufficient definitions, reliance on condition-specific and/or adult models of self-management, failure to consider the multitude of factors that influence patient self-management behavior, and lack of synthesis of research, clinical practice, and policy implications. To address this need, we present a comprehensive conceptual model of pediatric self-management that articulates the individual, family, community, and health care system level influences that impact self-management behavior through cognitive, emotional, and social processes. This model further describes the relationship among self-management, adherence, and outcomes at both the patient and system level. Implications for research, clinical practice, and health care policy concerning pediatric chronic care are emphasized with a particular focus on modifiable influences, evidence-based targets for intervention, and the role of clinicians in the provision of self-management support. We anticipate that this unified conceptual approach will equip stakeholders in pediatric health care to (1) develop evidence-based interventions to improve self-management, (2) design programs aimed at preventing the development of poor self-management behaviors, and (3) inform health care policy that will ultimately improve the health and psychosocial outcomes of children with chronic conditions.

Medical adherence in pediatric organ transplantation: what are the next steps?

PURPOSE OF REVIEW

Adherence within pediatric transplantation has gained importance as the complexities of long-term medical management of these patients are identified and knowledge regarding the negative consequences of nonadherence accumulates. We review recent findings to highlight gaps in the literature and make suggestions for future directions.

RECENT FINDINGS

Most research has focused on medication nonadherence, and a recent meta-analysis indicates that nonadherence is more prevalent in adolescent transplant recipients than in younger children. Nonadherence to other areas of the regimen (e.g. clinic attendance) may be even more common than medication nonadherence. However, work to date is based primarily on kidney and liver pediatric transplant patients, with a paucity of research on heart, lung and intestinal recipients. Risk factors for nonadherence after pediatric transplantation include poor family and child functioning. Intervention research remains rare. Challenges include the need for clearer definitions of what constitutes clinically significant nonadherence, longitudinal and prospective assessment of a wider range of potential risk factors, and the development and evaluation of interventions to treat or prevent nonadherence.

SUMMARY

Adherence research in pediatric transplantation is in its infancy. Significant opportunities exist to advance the field and create standards for effective identification, measurement, and treatment of nonadherence.

Self-reported non-adherence to immune-suppressant therapy in liver transplant recipients: demographic, interpersonal, and intrapersonal factors

Adherence to immune suppressants and follow-up care regimen is important in achieving optimal long-term outcomes after organ transplantation. To identify patients most at risk for non-adherence, this cross-sectional, descriptive study explores the prevalence and correlates of non-adherence to immune-suppressant therapy among liver recipients. Anonymous questionnaires mailed consisted of the domains: (i) adherence barriers to immune suppressants, (ii) immune suppressants knowledge, (iii) demographics, (iv) social support, (v) medical co-morbidities, and (vi) healthcare locus of control and other beliefs. Overall response was 49% (281/572). Data analyzed for those transplanted within 10 yr of study reveal 50% (119/237) recipients or 9.2/100 person years reporting non-adherence. Non-adherence was reported highest in the 2-5 yr post-transplant phase (69/123, 56%). The highest immune-suppressant non-adherence rates were in recipients who are: divorced (26/34, 76%, p=0.0093), have a history of substance or alcohol use (42/69, 61%, p=0.0354), have mental health needs (50/84, 60%, p=0.0336), those who missed clinic appointments (25/30, 83%, p<0.0001), and did not maintain medication logs (71/122, 58%, p=0.0168). Respondents who were non-adherent with physician appointments were more than four and a half times as likely (OR 4.7, 95% CI 1.5-14.7, p=0.008) to be non-adherent with immune suppressants. In conclusion, half of our respondents report non-adherence to immune suppressants. Factors identified may assist clinicians to gauge patients' non-adherence risk and target resources.

Inter-rater reliability of the Pediatric Transplant Rating Instrument (P-TRI): challenges to reliably identifying adherence risk factors during pediatric pre-transplant evaluations

The purpose of this study was to assess the inter-rater reliability of the P-TRI, a 17-item instrument developed to identify risk factors associated with poor treatment adherence in pediatric solid organ transplant candidates. Because factors influencing treatment adherence may vary with age, the 89 subject samples were divided into pre-adolescent (0-11 yr) and adolescent (12-19 yr) groups. Each subject received two independent P-TRI ratings based on pretransplant psychosocial assessments separately conducted by a PSYC and a SWTC. Inter-rater reliability was assessed using the delta statistic. Overall, agreement was higher in the pre-adolescent group, with delta>0.70 for five items and delta<0.30 for two items. For the adolescent group, one item had a delta>0.70 and seven items had a delta<0.30. Overall, PSYC P-TRI ratings indicated fewer areas of concern on items assessing family dynamics compared with SWTC P-TRI ratings, whereas the reverse was true for items related to psychiatric history. Results highlight the challenges of conducting a reliable pretransplant assessment of adherence-related risk factors and suggest the need for revisions to the P-TRI prior to its use in clinical practice.

A latent class analysis of psychiatric symptoms among 125 adolescents in a bariatric surgery program

OBJECTIVE

The purpose of this study was to examine whether subgroups could be identified among a sample of adolescents presenting for bariatric surgery.

METHODS

Participants were 125 severely obese adolescents enrolled in a bariatric surgery program referred for a psychiatric evaluation. A latent class analysis was conducted with self-report and clinician-rated measures of depressive symptoms, total problems by the Youth Self-Report Scale, anxiety severity, eating pathology, psychiatric diagnoses, quality of life, and family functioning.

RESULTS

A 3-class model yielded the best overall fit to the data. Adolescents in the ?eating pathology? class demonstrated high levels of both eating disordered and other psychopathology. The second class, or ?low psychopathology? class exhibited the fewest psychosocial problems, whereas adolescents in the third class were intermediate on measures of psychopathology, which is consistent with ?non-specific psychopathology.?

CONCLUSIONS

The latent class analysis identified homogeneous subgroups with different levels of psychopathology among a heterogeneous sample of severely obese adolescents. The identification of clinically relevant subgroups in this study offers an important initial means for examining psychopathology among adolescent bariatric surgery candidates and suggests a number of avenues for future research.

Adherence to medical recommendations and transition to adult services in pediatric transplant recipients

PURPOSE OF REVIEW

Nonadherence to treatment recommendations, especially when associated with transition to adult care providers, account, by some estimates, for most organ rejections and death in long-term pediatric survivors of solid organ transplantations. It is therefore imperative that providers become familiar with the issues related to those major risks and ways to address them.

RECENT FINDINGS

It is possible, and important, to routinely measure adherence to medications by using one of several available and proven methods of surveillance. There are numerous ways to improve adherence, and it is in fact possible to improve adherence and therefore outcomes in the transplant setting. The transition to adult services is a vulnerable period. The authors believe that it is possible to improve the transition process, and suggestions are presented in this review. However, solid research into interventions to improve transition is lacking.

SUMMARY

Nonadherence to medical recommendations is prevalent and leads to poor outcomes following otherwise successful pediatric transplantation. An especially vulnerable period is the time when a recipient transitions to adult care. Routine monitoring of adherence, evaluating and addressing barriers to adherence, and collaborative, multidisciplinary care are all expected to substantially improve adherence and reduce the risks associated with transition.

Psychosocial assessment prior to pediatric transplantation: a review and summary of key considerations

Prior to listing for transplantation, patients participate in a comprehensive, multidisciplinary evaluation. One component of this process, incorporated by the vast majority of transplant centers, is a psychosocial assessment conducted by a mental health professional. The primary objectives of a pre-transplant psychosocial assessment are to identify risk factors for difficulty adjusting post-transplant as well as behaviors that may compromise transplantation outcomes. This paper aims to provide a summary of key considerations for pediatric transplant teams describing what this assessment might include, when it should be performed, training requirements for the evaluators, how results of the evaluation might best be utilized and suggestions for optimal patient preparation. Our findings suggest that the evaluation, which can be conducted by a variety of professionals, should include assessment of patient knowledge and motivation for transplant, mental health and substance abuse history, presence or absence of family and social support, availability of financial resources, past history of treatment adherence, and the quality of the family's relationship with the transplant team. Repeat assessments and utilizing the initial evaluation for outcome assessment should be considered. Finally, the evaluation offers a unique opportunity for better preparing patients and families for transplantation.

Current lifestyle of young adults after liver transplantation during childhood

The authors studied the psychosocial adjustment of pediatric liver transplant (LT) recipients reaching adulthood. The study comprised phone interviews of 116 volunteers aged 17-33 years. Results were compared to those for healthy peers and 65 patients who were eligible for inclusion but did not participate. Participants' median age at LT was 6 years and the median period since LT was 15 years. Of the 116 participants, 76% considered their quality of life as good or very good. Seventy-five patients (65%) were attending schools, 27 of whom were 2 years or more below the age-appropriate level. Of the remaining 41 patients, 26 had a job and 15 were unemployed. Poor compliance with medications was reported by 52 patients (45%). Alcohol consumption was lower than in the reference population (p < 0.001). Anxiety, loneliness and negative thoughts were expressed by 53, 84 and 47% of the participants, respectively. Thirteen patients (11%) were being cared for by psychologists or psychiatrists. The 65 nonparticipants had greater psychological problems than the participants, and a lower educational level. In conclusion, after LT in early life, most patients displayed psychological vulnerability during early adulthood. The educational level of patients was lower than that of theirs peers.

Improved adherence and outcomes for pediatric liver transplant recipients by using text messaging

OBJECTIVE

The goal was to improve immunosuppressant adherence for pediatric patients with orthotopic liver transplants by using text messaging (TM).

METHODS

A prospective study of sending TM reminders to the primary medication administrator (patient or caregiver) for pediatric transplant recipients was performed. Patient records were reviewed, comparing the year before and the year of the study. The SD of serum tacrolimus levels was used as an indicator of adherence.

RESULTS

Forty-one patients provided consent. The median age was 15 years (range: 1-27 years), and the median age at the time of transplantation was 2 years (range: 4 months to 23 years). Fourteen patients (34%) were male. In 29 of 41 cases, the medications were self-administered by the patient. The mean duration of study was 13 +/- 1.5 months. Twenty-two patients were receiving 1 immunosuppressant, 14 were receiving 2, and 5 were receiving 3. Thirteen patients (37%) stopped the study after 4 months. The mean tacrolimus level SD decreased from 3.46 microg/L before the study to 1.37 microg/L (P < .005). The number of immunosuppressants taken and patient self/caregiver medication administration did not significantly affect the results. The number of acute cellular rejection episodes decreased from 12 to 2 during the study. Risk factors for rejection were older age (17.67 vs 13.28 years) and administration of >1 immunosuppressant.

CONCLUSION

We observed significant improvement in medication adherence and a reduction in rejection episodes with TM reminders for pediatric recipients of liver transplants.
