Compliance to immunosuppressants:how can it be improved in adolescent organ transplant recipients. Curr Opin Organ Transplant. 2010;15:614-620. [PMID: 20651598 DOI: 10.1097/mot.0b013e32833d3115]

Educational Needs of the Adolescent Transplant Recipient: A Developmental Approach to Understanding Transplant

BACKGROUND

As pediatric transplant patients reach adolescence, care teams must prepare them for an eventual transition to adult-oriented care. Care teams must provide patients with the necessary knowledge and skills to manage their medical needs independently, but the level of learning required to successfully self-manage a transplant is substantial. Furthermore, adolescence is also a dynamic developmental period that includes significant cognitive development and changes in social motivations.

METHODS

Within this report, we offer insights into some of the key developmental mechanisms of adolescence that may influence their learning in a medical context. We also review key concepts that should be included in patient education across a range of domains. Finally, we consider how patients with comorbid developmental disorders may require tailored education.

RESULTS

Key domains for education include (1) personal health history, (2) medication knowledge/adherence, (3) navigation of the healthcare system, and (4) communication with others about their health. Teams should intentionally track patient progress in their education, although few formalized tools are currently available to support tracking. Accommodations to learning for patients with developmental needs include varied instructional modalities (e.g., verbal, written, and modeling), opportunities to practice skills in a controlled manner, and establishment of family/community support that can persist into adulthood.

CONCLUSIONS

Education of transplant patients is a critical but long-term process that supports the successful transition to adulthood. Care teams should develop intentional plans to transfer knowledge and build skills across adolescence, while remaining open to adaptive approaches to support the learning of all patients.

Demographic Factors, Medication Adherence, and Post-transplant Health Outcomes: A Longitudinal Multilevel Modeling Approach

Few studies in pediatric solid organ transplantation have examined non-adherence to immunosuppressive medication over time and its associations with demographic factors and post-transplant outcomes including late acute rejection and hospitalizations. We examined longitudinal variation in patient Medication Level Variability Index (MLVI) adherence data from pediatric kidney, liver, and heart transplant recipients. Patient and administrative data from the United Network for Organ Sharing were linked with electronic health records and MLVI values for 332 patients. Multilevel mediation modeling indicated comparatively more variation in MLVI values between patients than within patients, longitudinally, over 10 years post transplant. MLVI values significantly predicted late acute rejection and hospitalization. MLVI partially mediated patient factors and post-transplant outcomes for patient age indicating adolescents may benefit most from intervention efforts. Results demonstrate the importance of longitudinal assessment of adherence and differences among patients. Efforts to promote medication adherence should be adapted to high-risk patients to increase likelihood of adherence.

Applications of motivational interviewing in adolescent solid organ transplant

BACKGROUND

Adolescence is a developmental period that is known for the highest risk of difficulties with adoption and maintenance of health behaviors for successful transplant. Motivational interviewing (MI) has been demonstrated to be an effective strategy in the management of modifiable factors impacting adherence in both adult transplant and analogous pediatric chronic illness populations.

AIMS

This paper describes MI and its applicability to adolescent transplant, providing examples of its potential use at each stage of the transplant journey.

MATERIALS AND METHODS

Literature on the principles and utilization of MI are reviewed, as well as the use of MI in adult transplant and similar pediatric populations.

RESULTS

Evidence suggests high applicability of concepts of MI to pediatric transplant.

DISCUSSION

Systems-level factors influencing health behavior change are discussed, along with the importance of recognizing and managing provider bias in MI-based interactions. MI does not require a licensed behavioral health provider to use it effectively; rather, it can be used by various multidisciplinary team members throughout the course of clinical care.

CONCLUSION

MI shows great promise as a useful intervention through all stages in the transplant journey. Though particularly well-suited to adolescents, its principles are effective across the lifespan, including with caregivers. It represents an interactional style for use by multidisciplinary team members in many patient-and caregiver-facing scenarios. As the goal is to support the patient's autonomy in decision-making, it is important for providers to recognize their own biases. Further resources for training are provided.

Telemedicine for Kidney Transplant Recipients: Current State, Advantages, and Barriers

Telemedicine is defined as the use of electronic information and communication technologies to provide and support healthcare at a distance. In kidney transplantation, telemedicine is limited but is expected to grow markedly in the coming y. Current experience shows that it is possible to provide transplant care at a distance, with benefits for patients like reduced travel time and costs, better adherence to medication and appointment visits, more self-sufficiency, and more reliable blood pressure values. However, multiple barriers in different areas need to be overcome for successful implementation, such as recipients' preferences, willingness, skills, and digital literacy. Moreover, in many countries, limited digital infrastructure, legislation, local policy, costs, and reimbursement issues could be barriers to the implementation of telemedicine. Finally, telemedicine changes the way transplant professionals provide care, and this transition needs time, training, willingness, and acceptance. This review discusses the current state and benefits of telemedicine in kidney transplantation, with the aforementioned barriers, and provides an overview of future directions on telemedicine in kidney transplantation.

Can eHealth applications improve renal transplant outcomes for adolescents and young adults? A systematic review

BACKGROUND AND OBJECTIVES

Adherence to medical treatment following a kidney transplant is particularly challenging during adolescence and young adulthood. There is increasing evidence of the benefits of the use of computer and mobile technology (labelled as eHealth hereafter) including serious gaming and gamification in many clinical areas. We aimed to conduct a systematic review of such interventions designed to improve self-management skills, treatment adherence and clinical outcomes in young kidney transplant recipients aged 16 to 30 years.

METHOD

The Cochrane Library, MEDLINE, EMBASE, PsychINFO, SCOPUS and CINAHL databases were searched for studies published between 01 January 1990 and 20 October 2020. Articles were short-listed by two independent reviewers based on pre-defined inclusion/exclusion criteria. Reference lists were screened and authors of published conference abstracts contacted. Two reviewers independently appraised selected articles, systematically extracted data and assessed the quality of individual studies (CASP and SORT). Thematic analysis was used for evidence synthesis; quantitative meta-analysis was not possible.

RESULTS

A total of 1098 unique records were identified. Short-listing identified four eligible studies, all randomized controlled trials (n = 266 participants). Trials mainly focused on mHealth applications or electronic pill dispensers (mostly for patients >18 years old). Most studies reported on clinical outcome measures. All showed improved adherence but there were no differences in the number of rejections. Study quality was low for all four studies.

CONCLUSIONS

The findings of this review suggest that eHealth interventions can improve treatment adherence and clinical outcomes for young kidney transplant patients. More robust and high-quality studies are now needed to validate these findings. Future studies should also extend beyond short-term outcomes, and consider cost of implementation. The review was registered with PROSPERO (CRD42017062469).

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.

Directly observed therapy to promote medication adherence in adolescent heart transplant recipients

PURPOSE

HT recipients experience high levels of medication non-adherence during adolescence. This pilot study examined the acceptability and feasibility of an asynchronous DOT mHealth application among adolescent HT recipients. The app facilitates tracking of patients' dose-by-dose adherence and enables transplant team members to engage patients. The DOT application allows patients to self-record videos while taking their medication and submit for review. Transplant staff review the videos and communicate with patients to engage and encourage medication adherence.

METHODS

Ten adolescent HT recipients with poor adherence were enrolled into a single-group, 12-week pilot study examining the impact of DOT on adherence. Secondary outcomes included self-report measures from patients and parents concerning HRQOL and adherence barriers. Long-term health outcomes assessed included AR and hospitalization 6 months following DOT.

FINDINGS

Among 14 adolescent HT patients approached, 10 initiated the DOT intervention. Of these, 8 completed the 12-week intervention. Patients and caregivers reported high perceptions of acceptability and accessibility. Patients submitted 90.1% of possible videos demonstrating medication doses taken. MLVI values for the 10 patients initiating DOT decreased from 6 months prior to the intervention (2.86 ± 1.83) to 6 months following their involvement (2.08 ± 0.87) representing a 21.7% decrease in non-adherence, though not statistically significant given the small sample size.

CONCLUSIONS

Result of this pilot study provides promising insights regarding the feasibility, acceptability, and potential impact of DOT for adolescent HT recipients. Further randomized studies are required to confirm these observations.

Medication Barriers and Adherence: Experiences of Pediatric Transplant Recipients

This study examined associations between scores on the Adolescent Medication Barriers Scale (AMBS) and the Parent Medication Barriers Scale (PMBS), patient and family factors, and medication adherence outcomes. Patients and caregivers from a pediatric solid organ transplantation (SOT) program were recruited for participation. Pediatric SOT recipients ages 10 to 21 years were eligible for participation. Analyses included reliability analyses and regression modeling with posttransplant medication adherence measured by Medication Level Variability Index scores. Seventy-three patients and caregivers completed an AMBS or PMBS questionnaire. Patient-caregiver inter-rater reliability was poor to fair. Greater medication barriers were reported among younger and female patients and families with more children. AMBS scores predicted greater nonadherence, while the PMBS was not predictive of adherence. Results point to the difficulty of assessing barriers to medication adherence and the lack of agreement between adolescent patients and caregivers. AMBS scores were more closely aligned with medication nonadherence, whereas PMBS scores may have been more influenced by family social factors. Adolescent reports of medication barriers may offer multidisciplinary transplant teams greater clinical utility when addressing these challenges with patients. Transplant social workers and psychologists should engage adolescents and caregivers in efforts to address medication nonadherence.

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.

Ethics of Organ Transplantation in Persons with Intellectual Disability

Historically, individuals with intellectual disability and end-stage organ disease were discriminated against by transplant professionals and often excluded from transplantation waitlists. Despite antidiscrimination legislation, some transplant programs continue to include intellectual disability as a relative, if not an absolute, contraindication to listing for an organ; this is true for both pediatric and adult individuals in end-stage organ disease. This commentary opposes the absolute exclusion of patients with intellectual disability and end-stage organ disease from transplantation waitlists provided that the candidates are expected to gain a predefined minimum benefit threshold of life-years and quality-adjusted-life years. Intellectual disability is one of many factors that should be considered in determining transplant eligibility and each candidate should have an individualized interdisciplinary assessment.

Care of Pediatric Solid Organ Transplant Recipients: An Overview for Primary Care Providers

As the number of living pediatric solid organ transplant (SOT) recipients continues to grow, there is an increased likelihood that primary care providers (PCPs) will encounter pediatric SOT recipients in their practices. In addition, as end-stage organ failure is replaced with chronic medical conditions in transplant recipients, there is a need for a comprehensive approach to their management. PCPs can significantly enhance the care of immunosuppressed hosts by advising parents of safety considerations and avoiding adverse drug interactions. Together with subspecialty providers, PCPs are responsible for ensuring that appropriate vaccinations are given and can play an important role in the diagnosis of infections. Through early recognition of rejection and posttransplant complications, PCPs can minimize morbidity. Growth and development can be optimized through frequent assessments and timely referrals. Adherence to immunosuppressive regimens can be greatly improved through reinforcement at every encounter, particularly among adolescents. PCPs can also improve long-term outcomes by easing the transition of pediatric SOT recipients to adult providers. Although guidelines exist for the primary care management of adult SOT recipients, comprehensive guidance is lacking for pediatric providers. In this evidence-based overview, we outline the main issues affecting pediatric SOT recipients and provide guidance for PCPs regarding their management from the first encounter after the transplant to the main challenges that arise in childhood and adolescence. Overall, PCPs can and should use their expertise and serve as an additional layer of support in conjunction with the transplant center for families that are caring for a pediatric SOT recipient.

Transplantation and Adherence: Evaluating Tacrolimus Usage in Pediatric Patients With Cancer

BACKGROUND

Researchers have estimated that about 50% of pediatric patients with chronic illness adhere to tacrolimus therapy, a medication responsible for preventing critical side effects in patients undergoing hematopoietic stem cell transplantation (HSCT).

OBJECTIVES

The purpose of this study was to describe patient adherence to tacrolimus by reviewing documentation from the electronic health record and therapeutic drug levels.

METHODS

This retrospective descriptive study examined 357 clinic visits by 57 patients undergoing HSCT. Direct (tacrolimus levels) and indirect (subjective reporting) measures were evaluated.

FINDINGS

The authors found that, in 51% of visits, adherence was not documented. The overall nontherapeutic drug level rate was 60%. Because of the small sample size, nonadherence did not statistically correlate with nontherapeutic levels. The findings highlight the need for adherence awareness, assessment, and documentation in clinical practice.

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.

Home quarantine compliance is low in children with fever during COVID-19 epidemic

BACKGROUND

The coronavirus disease 2019 (COVID-19) outbreak began in China at the end of 2019. The disease is highly infectious. In order to prevent and control the epidemic situation, the state has issued a series of measures to guide the prevention and control of the epidemic. At the same time, it also introduced the measure of home isolation for children with fever. However, due to the nature of children, the implementation of the home isolation turned out to be quite difficult, and questions regarding the home isolation were brought out by parents when seeing doctors. For this reason, we decided to conduct this study.

AIM

To study factors that influence home quarantine compliance in children with fever during the COVID-19 epidemic.

METHODS

A total of 495 paediatric patients with respiratory tract infection and fever were selected from the general fever clinic at Xiamen Children's Hospital from February 6-27, 2020. On day 8 after the hospital visit, follow-up was conducted by telephone to evaluate the compliance of home quarantine.

RESULTS

Among the ten quarantine measures, the proportion of families adhering to keeping 1.5 m distance, proper hand hygiene, wearing masks at home, and proper cough etiquette was very low (< 30% for each measure). Our analysis showed that compliance was related to gender and age of children, gender and age of primary caregiver, number of children in the family, and intensity of information on quarantine measures. We observed that compliance increased with the age of children. Compared with children whose caregivers were young adults, children with elderly caregivers were 2.461 times more likely to show poor compliance. Furthermore, children who received intensive information on quarantine measures had significantly better compliance.

CONCLUSION

Compliance of children with fever to quarantine measures at home is low during the COVID-19 epidemic. Strengthening education on the quarantine measures is critical to improve compliance, in particular in young children with elderly caregivers.

Health literacy and its association with adherence in pediatric liver transplant recipients and their parents

OBJECTIVE

Non-adherence to pediatric regimens is a common concern. Low health literacy is correlated with poor outcomes in adults but is understudied in pediatrics. The current project aimed to determine the relationship between health literacy, adherence, and outcomes in pediatric liver transplant recipients. Hypotheses included a) parent and patient health literacy would be positively correlated; and b) low patient and/or parent health literacy would be negatively correlated with adherence and health outcomes.

PATIENTS AND METHODS

Eligible participants were recruited during routine follow-up visits in a pediatric liver transplant clinic. Parents and patients (>13 years old) completed 2 measures of health literacy. Patients ≥18 years completed health literacy measures without corresponding parent surveys. Adherence variables and health outcomes were obtained from medical records.

RESULTS

Seventy-nine patients across two sites completed the study. Variance in classification of health literacy between measures was observed; however, most parents (82%-100%) scored within an "adequate literacy" range. More adolescents scored in lower health literacy ranges relative to the parents. Markers of SES were positively correlated with health literacy. Parent health literacy was negatively associated with biopsy-proven rejection episodes and the number of hospitalizations; however, it was not associated with measures of tacrolimus adherence. There were no relationships observed between parent and adolescent health literacy.

CONCLUSIONS

Health literacy is an important consideration in managing patient care; however, available measures demonstrate variability in capturing the skills of patients. Effective communication strategies may ameliorate admittedly small, but negative, impacts of limited health literacy on outcomes.

Longitudinal Barriers to Thiopurine Adherence in Adolescents With Inflammatory Bowel Diseases

Objectives

Cross-sectionally, more adherence barriers are associated with lower medication adherence. However, little is known about longitudinal associations between adherence barriers and adherence. Among adolescents with inflammatory bowel diseases (IBD), this study examined both (1) how time-varying self-reported adherence barriers affect daily thiopurine adherence and (2) how adherence barriers at baseline affect daily thiopurine adherence over a six-month period.

Methods

Eighty-one adolescents 11-18 years old prescribed a once-daily oral IBD maintenance medication participated in a six-month observational study. Adherence barriers were self-reported monthly via the Medication Adherence Measure (MAM): Medication Subscale. Daily adherence estimates were collected via Medication Event Monitoring System (MEMS) Track Caps.

Results

Generalized linear mixed modeling indicated that time alone did not significantly predict whether one was more likely to be adherent (p = .602). However, increasing adherence barriers lowered the likelihood that a participant would be adherent on a given day, and the interaction between time and barriers predicted likelihood of adherence on a given day (p < .01). Specifically, when participants reported no adherence barriers at baseline, adherence did not significantly change over time (p = .369). However, when barriers were endorsed, adherence decreased over time (p < .01).

Conclusions

Fewer adherence barriers over time predicted greater likelihood of adherence on a given day, which is consistent with previous cross-sectional research. Routine assessment of barriers to adherence over the course of adolescence is critical in addressing suboptimal adherence behavior in youth with IBD.

Implementing a Home-Based Telehealth Group Adherence Intervention with Adolescent Transplant Recipients

Introduction: To improve access to care and engage adolescent transplant recipients for adherence-promoting interventions, innovative solutions utilizing technology are needed. Materials and Methods: This study describes the implementation of a five-session group intervention targeting medication adherence in adolescent transplant recipients through home-based telemedicine. Results: Seven videoconferencing groups were conducted with a total of 33 participants living a median of 57 miles away from their transplant medical center. The median coefficient of variation (CV) of tacrolimus (immunosuppression medication) decreased from 32.2% to 23.5% from the pregroup to postgroup phase. Analyses indicated that the group was acceptable and engaging for participants, as highlighted by one participant reporting, "I liked how me and the group members came together… it felt like a little family." Overall satisfaction with the group and with the technology was endorsed by 86%. The group intervention was generally feasible; however, there were technological difficulties reported by participants and the facilitator, particularly given the diversity of the home-based connections and equipment. Other adaptations helped improve recruitment, attendance, and participation. Discussion: Implementing a telehealth group can pose unique challenges, especially with a group of adolescent participants. Although nonsignificant, we observed a decrease in the median CV of tacrolimus, indicating that medication adherence generally improved after group intervention. Our experience facilitating these groups provides insights into strategies to optimize feasibility and the participant experience. Distance of participants from the hospital is an important consideration and provides a strong rationale for the need for telemedicine-enabled approaches. We explore and discuss the challenges to implementing a home-based group, suggest practical strategies and developmentally sensitive adjustments when working with adolescents, and propose strategies to prepare clinicians for obstacles that may present when implementing a telehealth group with youth.

Quality of life in children with kidney transplant: Systematic review

OBJECTIVE

To identify in the literature studies that evaluate the quality of life in pediatric patients with kidney transplant through use of specific, validated instruments in Pediatrics.

METHOD

Systematic review of the literature with searches conducted in the following databases: Medline, PubMed, LILACS, CINAHL, SciELO and Cochrane Library. Main keywords: Quality of life, Kidney transplantation and Pediatrics.

RESULTS

A total of 366 studies were selected and eight observational studies were included that evaluated the quality of life of children with kidney transplant by means of evaluation instruments of quality of life.

CONCLUSION

The quality of life of children with kidney transplant is inferior compared to healthy children. The post-transplant period presents better results compared to pre-transplant children. The identification of mental, physical and social conditions related to the quality of life of this population allows for better planning the assistance provided to them.

Web-Based Tailored Intervention to Support Optimal Medication Adherence Among Kidney Transplant Recipients: Pilot Parallel-Group Randomized Controlled Trial

Background

Optimal immunosuppressive medication adherence is essential to graft survival. Transplant-TAVIE is a Web-based tailored intervention developed to promote this adherence.

Objective

The objective of our study was to evaluate the Transplant-TAVIE intervention’s acceptability, feasibility, and preliminary efficacy.

Methods

In a pilot, parallel-group, randomized controlled trial, we randomly assigned a convenience sample of 70 kidney transplant patients on immunosuppressive medication either to an experimental group (Transplant-TAVIE) or to a control group (existing websites). Kidney transplant recipients had to be older than 18 years, be taking immunosuppressant medication, and have access to the internet to participate in this study. Transplant-TAVIE was composed of three interactive Web-based sessions hosted by a virtual nurse. We documented user appreciation of and exposure to the intervention. Furthermore, we assessed medication adherence, medication self-efficacy, intake-related skills, and medication side effects at baseline and 3 and 6 months later. Analyses of variance were used to assess intergroup differences over time.

Results

After baseline questionnaire completion, participants were randomly assigned either to Transplant-TAVIE (n=35) or to the websites (n=35) group. All participants had received their kidney graft <1 year to 32 years earlier (mean 6.8 years). Of the experimental group, 54% (19/35) completed the sessions of Transplant-TAVIE. Users found the intervention to be acceptable—33% were extremely satisfied (6/18), 39% were very satisfied (7/18), and 28% were satisfied (5/18). At baseline and over time, both experimental and control groups reported high medication adherence, high medication self-efficacy, and frequent use of skills related to medication intake. No intergroup differences emerged over time.

Conclusions

The results of this study support the feasibility and acceptability of Transplant-TAVIE. It could constitute an accessible adjunct in support of existing specialized services.

Cell phone support to improve medication adherence among solid organ transplant recipients

For many adolescent and young adult solid organ transplant recipients, medication non-adherence is a mortal issue. This study investigated the feasibility, acceptability, and potential efficacy of a 12-week cell phone support intervention to improve immunosuppressant medication adherence. A small sample (N = 8) of non-adherent adolescent and young adult transplant recipients, aged 15-20.5 years, was enrolled. Cell phone support consisted of short calls each weekday including medication reminders, discussion of needs, problem-solving support, and promotion of clinic and community resources. Changes in adherence were measured by self-report and laboratory values, and intervention acceptability, adherence barriers, social support, depression, and substance use were assessed by self-report. Pre-post effect sizes showed medium-to-large improvements in adherence, lasting through a 12-week follow-up assessment. There were also small-to-medium changes in adherence barriers, social support, and depression. However, acceptability and feasibility were limited, due to a low rate of enrollment by eligible male participants. Cell phone support interventions may promote medication adherence among adolescents and young adults. Cell phone support warrants further investigation, including a randomized controlled trial to evaluate efficacy.

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.

Meeting report: FDA public meeting on patient-focused drug development and medication adherence in solid organ transplant patients

The Food and Drug Administration (FDA) held a public meeting and scientific workshop in September 2016 to obtain perspectives from solid organ transplant recipients, family caregivers, and other patient representatives. The morning sessions focused on the impact of organ transplantation on patients' daily lives and the spectrum of activities undertaken to maintain grafts. Participants described the physical, emotional, and social impacts of their transplant on daily life. They also discussed their posttransplant treatment regimens, including the most burdensome side effects and their hopes for future treatment. The afternoon scientific session consisted of presentations on prevalence and risk factors for medication nonadherence after transplantation in adults and children, and interventions to manage it. As new modalities of Immunosuppressive Drug Therapy are being developed, the patient perceptions and input must play larger roles if organ transplantation is to be truly successful.

Clinical Indices Can Standardize and Monitor Pediatric Care: A Novel Mechanism to Improve Quality and Safety

OBJECTIVE

The Cancer Care Index (CCI), a single metric that sums the number of undesirable patient events in a given time frame (either preventable harm events or missed opportunities to provide optimal care), resulted in a 42% improvement in performance. Our objective was to test the index concept in other service lines to determine whether similar performance improvement occurred.

STUDY DESIGN

Care indices were developed and introduced in 3 additional service lines: Nephrology (Chronic Kidney Disease Care Index; CKDCI), Pulmonology (Lung Transplantation Care Index; LTCI), and Otolaryngology (Tracheostomy Care Index; TCI). After reaching agreement on specific harms to be avoided and elements of optimal care that should be reliably delivered, these items were compiled into indices that were updated monthly. Reports included each element individually and the total for all elements. Baseline performance was calculated retrospectively for the previous year.

RESULTS

Significant improvement in performance occurred in each program following implementation of the clinical indices. The CKDCI was decreased by 63.2% (P < .001), the LTCI was decreased by 89.5% (P < .001), and the TCI was decreased by 53.0% (P < .001). Surveyed staff indicated satisfaction with use of the metric.

CONCLUSIONS

Clinical indices are useful for evaluating and managing the overall reliability of a program's ability to deliver optimal care, and are associated with improved clinical performance and satisfaction by service line staff when incorporated into a program's operation.

Medication adherence among adolescent solid-organ transplant recipients: A survey of healthcare providers

The aim of this study was to assess healthcare provider perspectives on barriers to medication adherence and to discover recommendations for interventions among providers of pediatric solid-organ transplant patients. An anonymous online survey was administered to a multidisciplinary pool of pediatric transplant providers from February 2015 to March 2016. It consisted of 15 questions regarding transplant providers' attitudes, clinical practice, and beliefs pertaining to medication adherence among teenage solid-organ transplant recipients. Data were analyzed using descriptive statistics. Responses to open-ended questions were coded and categorized into themes. One hundred ten surveys were completed by providers specializing in pediatric heart, kidney, liver, lung, and/or intestinal transplantation. Commonly cited reasons for poor adherence were forgetting/poor planning (94%), the desire to be normal (86%), lack of support (86%), and poor parental monitoring (79%). Suggestions to improve adherence included increasing peer and family support, providing education, and incorporating technology into adherence regimens. Barriers to adherence in transplant patients are recognized by providers and are both similar to and disparate from patient and family identified barriers published in the literature. Providers recognize the importance of education, social support, and technologically driven interventions on improving outcomes in the transplant population.

Cluster analysis for family management of Chinese children with chronic kidney diseases

This study aimed to identify patterns of family management and its predictors based on the perception of the care experience from 339 caregivers of Chinese children with chronic kidney disease in multiple medical centers. Each caregiver completed the Family Management Measure questionnaires. Cluster analysis generated five patterns: effective (12.7%), impaired (14.5%), burdensome (21.2%), disorganized (27.7%), and concerning (23.9%). Multinomial logistic regression indicated that child's age, disease duration, family income, and paternal employment predicted cluster membership. Findings assist healthcare providers to distinguish families that need more help and the areas in which to intervene to promote families' overall coping and adaptation.

Adherence and the pediatric transplant patient

Adherence is proving to be the Achilles heel of pediatric transplantation. Through a careful literature review on adherence in pediatric solid-organ transplantation from 2007 to 2017, this chapter reports on the incidence, measuring tools, and consequences of poor adherence. We detail adherence determinants and interventions proposed to foster it. While adherence is a major problem in the adolescent age, it clearly is not limited to this age group. Importantly, it is not one to start tackling at that time or when it becomes apparent. Rather, fostering adherence should be built throughout the continuum of the transplant journey, starting in the pretransplantation phase. Adherence is clearly a fluid state, necessitating frequent reassessments and enforcement. Adherence in addition shares similar determinants with quality of life. The severe consequences in the case of poor adherence mandate that the transplant community prioritize it as the next frontier in transplantation. Good adherence is what will pave the road to tolerance, cost-efficient transplantation, and optimized long-term outcomes.

Psychosocial predictors of medication adherence in pediatric heart and lung organ transplantation

Few studies have identified the psychosocial characteristics of those children and their families associated with future non-adherence to immunosuppressive medications following a heart or lung transplant. UNOS data and medical records information were used to test the association between patient and family psychosocial characteristics and medication adherence. Medication adherence outcomes were obtained using the physician assessments in the UNOS data and measured through patient-level standard deviation scores of immunosuppressive medication blood levels. Complete data were collected on 105 pediatric heart and lung transplant recipients and their families. Multivariate, stepwise analyses were conducted with each adherence outcome. Physician reports of adherence were associated with age of the child at transplantation, parental education, two-parent families, significant psychosocial problems, and the pretransplant life support status of the child. The resulting model (χ² =28.146, df=5, P<.001) explained approximately 39.5% of the variance in physician reports of adherence (Nagelkerke r² =.395). Blood level standard deviation scores were predicted by age at transplant (F=5.624, P=.02, r² =.05). Results point to the difficulties experienced by children and families when undergoing a heart or lung transplantation. Efforts to develop standardized and evidence-based pretransplant psychosocial assessments in pediatric populations are suggested, especially those surrounding familial risk factors.

Research Needs for Effective Transition in Lifelong Care of Congenital Genitourinary Conditions: A Workshop Sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases

Over the last 5 decades, health-care advances have yielded quantum improvements in the life expectancy of individuals with congenital genitourinary conditions (CGCs), leading to a crisis of care. Many individuals with CGC enter adulthood unprepared to manage their condition. Pediatric CGC specialists lack training to manage adulthood-related health-care issues, whereas adult genitourinary specialists lack training within the context of CGCs. To address these challenges, the National Institutes of Diabetes and Digestive and Kidney Diseases convened individuals with CGCs and experts from a variety of fields to identify research needs to improve transitional urology care. This paper outlines identified research needs.

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.

Longitudinal stability of specific barriers to medication adherence

OBJECTIVE

Higher levels of barriers are related to lower medication adherence and negative medical outcomes in pediatric transplant recipients. Although total number of barriers appears to be stable over time, it is unclear whether the same is true for specific barriers. This study examined the frequency of endorsement and the stability of specific barriers over 18 months.

METHOD

Participants included 63 parents and 51 adolescents and young adults. Transplant types included 39 kidneys, 16 livers, 10 hearts, and 1 double lung. Participants completed measures of perceived barriers to adherence at Time 1 (T1) and Time 2 (T2).

RESULTS

The majority of parent- and adolescent-reported specific barriers showed a positive relationship from T1 to T2. Few specific barriers showed significant differences in the level of endorsement between time points.

CONCLUSION

Specific barriers to medication adherence tend to be stable over time. Patients' specific barriers appear unlikely to change without targeted intervention.

Hypertension and obesity after pediatric kidney transplantation: management based on pathophysiology: a mini review

Hypertension after pediatric renal transplant is a common and important risk factor for graft loss and patient survival. The mechanism of post kidney transplant hypertension is complex and multifactorial. Control of blood pressure in renal transplant patients is important but often times blood pressures remain uncontrolled. The management of hypertension and obesity in pediatric kidney transplant patients is based on the pathophysiology. Compared to the general pediatric hypertensive population, special attention needs to be focused on the additional impact of immunosuppressive medications side effects and interactions, recurrent disease, and donor and recipient comorbidities such as obesity on blood pressure control with thoughtful consideration of the risk of graft failure. In general, there is a need for prospective studies in pediatric kidney transplant patients to understand the pathophysiology of hypertension and obesity and the appropriate approach to achieve a balance between the primary need to avoid rejection and the need to lower blood pressure and prevent obesity.

Tolerance--is it worth it?

We are entering an exciting time in the study of immunologic tolerance. Several cellular and molecular strategies have been developed that show promise in nonhuman transplant models and these approaches are just now appearing in clinical trials. Tolerance strategies that prevent immune rejection and obviate the need for immunosuppressive medications (with inherent risk of cancer, infection, and organ toxicity) would improve both graft and patient survival. Each tolerance protocol brings its own set of associated risks. As the results of these trials become available, we must continue to evaluate their successes and failures. The balance of these outcomes will help us answer the question: "Tolerance-Is it worth it?"

Conversion from twice- to once-daily tacrolimus in pediatric kidney recipients: a pharmacokinetic and bioequivalence study

BACKGROUND

The objectives of this study were to investigate pharmacokinetic and pharmacogenetic parameters during the conversion on a 1:1 (mg:mg) basis from a twice-daily (Prograf) to once-daily (Advagraf) tacrolimus formulation in pediatric kidney transplant recipients.

METHODS

Twenty-four-hour pharmacokinetic profiles were analyzed before and after conversion in 19 stable renal transplant recipients (age 7-19 years). Tacrolimus pharmacokinetic parameters [area under the concentration-time curve (AUC0-24), minimum whole-blood concentration (Cmin), maximum whole-blood concentration (Cmax), and time to achieve maximum whole-blood concentration (tmax)] were compared between Tac formulations and between CYP3A5 and MDR1 genotypes after dose normalization.

RESULTS

Both AUC0-24 and Cmin decreased after conversion (223.3 to 197.5 ng.h/ml and 6.5 to 5.6 ng/ml; p = 0.03 and 0.01, respectively). However, the ratio of the least square means (LSM) for AUC0-24 was 90.8 %, with 90 % CI limits of 85.3 to 96.7 %, falling within bioequivalence limits. The CYP3A5 genotype influences the dose-normalized Cmin with the twice-daily formulation only.

CONCLUSIONS

Both tacrolimus formulations are bioequivalent in pediatric renal recipients. However, we observed a decrease in AUC0-24 and Cmin after the conversion, requiring close pharmacokinetic monitoring during the conversion period.

Managing bronchiolitis obliterans syndrome (BOS) and chronic lung allograft dysfunction (CLAD) in children: what does the future hold?

The success of pediatric lung transplantation continues to be limited by long-term graft dysfunction. Historically this has been characterized as an obstructive spirometric defect in the form of the bronchiolitis obliterans syndrome (BOS). It is recognized, however, that this does not reflect many of the other acknowledged etiologies of chronic lung dysfunction-noting it is the sum of the parts that contribute to respiratory morbidity and mortality after transplant. The term chronic lung allograft dysfunction (CLAD) has been coined to reflect these other entities and, in particular, a group of relatively recently described lung disorders called the restrictive allograft syndrome (RAS). RAS is characterized by a restrictive spirometric defect. Although these entities have not yet been studied in a pediatric setting their association with poor compliance, antibody-mediated rejection (AMR), and post-infectious lung damage (particularly viral) warrants attention by pediatric lung transplant teams. Current therapy for the BOS subset of CLAD is otherwise limited to changing immunosuppressants and avoiding excessive infectious risk by avoiding over-immunosuppression. Long-term macrolide therapy in lung transplantation is not of proven efficacy. Reviewing previous BOS studies to explore restrictive spirometric cases and joint projects via groups like the International Pediatric Lung Transplant Collaborative will be the way forward to solve this pressing problem.

A systematic review of self-management interventions for children and youth with physical disabilities

PURPOSE

Evidence shows that effective self-management behaviors have the potential to improve health outcomes, quality of life, self-efficacy and reduce morbidity, emergency visits and costs of care. A better understanding of self-management interventions (i.e. programs that help with managing symptoms, treatment, physical and psychological consequences) is needed to achieve a positive impact on health because most children with a disability now live well into adulthood.

METHOD

A systematic review of self-management interventions for school age youth with physical disabilities was undertaken to assess their effectiveness. Comprehensive electronic searches using international web-based reference libraries were conducted for peer-reviewed and gray literature published between 1980 and January 2012. Eligible studies examined the effectiveness of self-management interventions for children and youth between 6 and 18 years of age with congenital or acquired physical disabilities. Studies needed to include a comparison group (e.g. single group pre/post-test design) and at least one quantifiable health-related outcome.

RESULTS

Of the 2184 studies identified, six met the inclusion criteria; two involved youth with spina bifida and four with juvenile arthritis. The majority of the interventions ran several sessions for at least 3 months by a trained interventionist or clinician, had one-to-one sessions and meetings, homework activities and parental involvement. Although outcomes varied between the studies, all of the interventions reported at least one significant improvement in either overall self-management skills or a specific health behavior.

CONCLUSIONS

While self-management interventions have the potential to improve health behaviors, there were relatively few rigorously designed studies identified. More studies are needed to document the outcomes of self-management interventions, especially their most effective characteristics for children and youth with physical disabilities. Implications for Rehabilitation There is some evidence to suggest that self-management interventions for children and youth with spina bifida and arthritis can improve self-management behaviors and health outcomes. Parents' involvement should be considered in encouraging self-management behaviors at different stages of their child's development. Much work is needed to explore the longer term implications of self-management interventions for youth with physical disabilities as well as the impact on health care utilization.

Inferior allograft outcomes in adolescent recipients of renal transplants from ideal deceased donors

OBJECTIVE

To measure the impact of the Share-35 policy on the allocation of ideal deceased donor kidneys and to examine the impact of age on outcomes after kidney transplantation using ideal donor kidneys.

BACKGROUND

In the United States, through Share-35, transplant candidates aged 18 years or younger receive priority for the highest-quality deceased donor kidneys. Adolescent (15-18 years) kidney transplant recipients (KTRs), however, may be more susceptible to allograft loss due to elevated rates of acute rejection and a possible increased risk of primary renal disease recurrence.

METHODS

We used registry data to perform a retrospective cohort study of 39,136 KTRs from January 1, 1994, to December 31, 2008. Ideal donors were defined as 2 to 34 years old with creatinine <1.5 mg/dL and absence of hypertension, diabetes, and hepatitis C.

RESULTS

After Share-35, the percentage of ideal donor kidneys allocated to pediatric recipients increased from 7% to 16%. In multivariable Cox regression, compared with adolescent KTRs, all age strata except recipients older than 70 years had a lower risk of allograft failure (P < 0.01 for each comparison); results were similar after excluding KTRs with diseases at high risk of recurrence. Adolescent recipients had higher mortality rates than KTRs younger than 14 years, similar mortality compared with that of KTRs older than 18 and younger than 40 years, and lower mortality than KTRs older than 40 years.

CONCLUSIONS

The allocation of "ideal donors" to adolescent recipients may not maximize graft utility. Reevaluation of pediatric allocation priority may offer opportunities to optimize ideal renal allograft survival.

Working Together as a Team: Adolescent Transplant Recipients and Nurse Practitioners

Nurse practitioners are a critical part of the transplant team, enhancing the quality of patient care with their knowledge and skill with respect to disease-specific populations of patients. Adolescent transplant recipients are a vulnerable population and require specific considerations. Nurse practitioners can successfully tailor care to the adolescent developmental stages in order to promote quality of life, adherence to the medical regimen, and successful transition to adult transplant centers and to minimize risk-taking behaviors. Teamwork between the patient's family and the entire transplant team is important to optimize not only the patient's health but also to ensure quality of life after transplant. Adolescents can be especially challenging after transplant, given their complex and evolving psychosocial and cognitive development. Nurse practitioners are in a unique position to be central in adolescents' successful adaptation to their medical condition. Facilitating identification and management of medication-related side effects, awareness of emotional health and quality of life, adherence to the medical regimen, and eventual transition to adult caregivers all remain critically important steps in care that are ideally suited for advance practice leadership.
