Abstract
BACKGROUND As survival in pediatric heart transplantation (HTx) has improved due to medical advances, the analysis of long-term outcomes impacting quality of life such as cognition and development becomes increasingly important. Neuropsychological assessments provide a comprehensive understanding of individual needs, allowing for the development of tailored recommendations and interventions. METHODS Routine neuropsychological assessment was completed between 5 and 7 years of age in this cohort of pediatric HTx recipients at our center (Jan 2014-Oct 2018), including tests of general intellect (WPPSI-IV, WISC-V), academics (WIAT-II/III), perceptual-motor abilities (Beery VMI), and memory (CMS). Relevant medical variables were collected. RESULTS Among 25 children, the median age at testing was 6.7 (IQR:5.8-7.4) years, with a median time since HTx of 5.2 (IQR:4.8-6.8) years. Medical diagnoses included congenital heart disease (CHD; 56%) and cardiomyopathy (44%). Cognitive functioning across the intellectual, academic, and perceptual-motor domains fell within the low-average range, while memory abilities fell within the average range. DSM-5 clinical diagnoses were provided for 14 (56%) children: Intellectual Disability-Mild (20%), Learning Disability (20%), Language Disorder (8%), and Attention-Deficit/Hyperactivity Disorder (12%). The presence of neurological issues and/or CHD predicted poorer performance on various neuropsychological domains. CONCLUSIONS Over 50% of this cohort of pediatric heart transplant recipients seen for routine post-HTx neuropsychological assessment received a clinical psychological diagnosis, notably higher than rates in the general population. This population requires monitoring to ensure that high risk children are identified and successfully supported in school and their community.

Educational and learning morbidity in pediatric heart transplant recipients: A pediatric heart transplant society study. Pediatr Transplant 2020; 24:e13711. [PMID: 32320118 DOI: 10.1111/petr.13711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Revised: 02/28/2020] [Accepted: 03/20/2020] [Indexed: 11/29/2022]
Abstract
Educational development is an important component of quality of life for children with heart transplant. Aims include determining prevalence of and risk factors for modified education placement in a large representative sample of pediatric heart transplant recipients. Participants included 1495 patients (age 6-18 years) from the PHTS database. Data on education placement and clinical predictors were collected at listing and at 1 and 3 years post-transplant. At listing, 88% of patients were in typical education placement, while 12% were in modified education. Males (P = .02), those with CHD (P < .0001), those with non-private insurance (P < .0001), and those with longer hospital stay (P = .001) were more likely to be in a modified education placement at time of listing. Age, race, listing status, mechanical support, and waitlist time were not significantly associated with placement. The prevalence of typical education placement was similar (87% at 1-year and 86% at 3-year) post-transplant. Predictors of modified education placement at 3-year follow-up included placement at listing (OR = 12.9 [95% CI 7.6-21.9], P < .0001), non-private insurance (OR = 2.0 [95% CI 1.3-3.2], P = .001), CHD (OR = 1.8 [95% CI 1.1-2.7, P = .01), history of post-transplant infection (OR = 1.9 [95% CI 1.2-2.9, P = .007), and number of post-transplant infections (OR = 1.3 [95% CI 1.1-1.5, P = .002). Among pediatric heart transplant recipients, males, those with non-private insurance, those with CHD, and those who experience post-transplant infections are at greatest risk for modified academic placement, which persists for several years post-transplant and deserves targeted intervention.

Abstract
Background Proton beam therapy (PBT) is available in many western and Asian countries, but there is no clinical, gantry-based PBT facility in Canada. Methods A cost analysis was conducted from the Alberta Ministry of Health perspective with a 15-year horizon. Estimated costs were: PBT unit, facility development as part of an ongoing capital project, electricity, maintenance contract, and staffing. Revenues were: savings from stopping USA referrals, avoiding the costs of standard radiation therapy (RT) for Albertans receiving PBT instead, and cost-recovery charges for out-of-province patients. Results The Ministry of Health funded 15 Albertans for PBT in the USA in the 2014/15 fiscal year (mean CAD$ 237,348/patient). A single-vault, compact PBT unit operating 10 hours/day could treat 250 patients annually. A 100 Albertans, with accepted indications, such as the curative-intent treatment of chordomas, ocular melanomas, and selected pediatric cancers, would likely benefit annually from PBT’s improved conformality and/or reduced integral dose compared to RT. The estimated capital cost was $40 million for a single beamline built within an ongoing capital project. Operating costs were $4.8 million/year at capacity. With 50% capacity reserved for non-Albertans at a cost recovery of $45,000/patient, a Western Canadian PBT facility would achieve net positive cash flow by year eight of clinical operations, assuming Alberta-to-USA referrals reach 21 patients/year by 2024 and increase at 3%/year thereafter. Sensitivity analysis indicates the lifetime net savings is robust to the assumptions made. Conclusion This business case, based on Canadian costing data and estimates, demonstrates the potential for a financially viable PBT facility in Western Canada.

Abstract
OBJECTIVES Cost data for pediatric heart transplantation are scarce. We examined hospital cost of the national pediatric heart transplantation program in Australia and assessed factors associated with increased costs. METHODS The hospital cost of all children who underwent heart transplantation at a national referral center between January 2003 and June 2015 and were followed more than 1 year was retrospectively analyzed. Lifetime follow-up costs were adjusted for quality of life and projected to life expectancy. All costs were reported in 2016 US dollars. RESULTS Of 70 children who underwent heart transplantation in the study period, 61 were followed more than 1 year after transplantation (mean, 4.3 ± 2.5 years). Mean cost of primary heart transplantation was $278,480 (95% confidence interval, 219,282-337,679) and did not change over time. Pretransplant mechanical circulatory support was required in 36% (22/61) of children. On multivariable analysis, greater admission costs were associated with ventricular assist device and pretransplant length of stay. Mean annual follow-up cost after discharge was $55,823 (95% confidence interval, 47,631-64,015) in the first year and $12,119 (95% confidence interval, 8578-15,661) thereafter. Increased first-year follow-up costs were associated with endomyocardial biopsies and length of readmissions. Cost per quality-adjusted life-year gained varied from $29,161 to $44,481 on sensitivity analysis. Freedom from treated rejections was 65.5% at 1 year, 63.2% at 3 years, and 59.5% at 5 years. Endomyocardial biopsies contributed to 52% of first-year follow-up costs. CONCLUSIONS Primary pediatric heart transplantation in Australia is cost-effective for long-term survivors, even for those supported by ventricular assist device. Surveillance endomyocardial biopsy was a major contributor to post-transplantation costs. Selective targeting of surveillance biopsies may be cost-saving.

Abstract
The objective of this study is to describe the neurologic, neurocognitive, and functional outcomes of children aged under 6 years supported on the Berlin Heart EXCOR ventricular assist device (VAD) followed in the Complex Pediatric Therapies Follow-up Program (CPTFP). Sixteen patients were prospectively followed through this longitudinal, developmental program. The patients were evaluated with neurologic physical examination. Intelligence quotients (IQ) and functional outcome scores (ABAS-II scores) were obtained. Neuroimaging reports from before, during, and after VAD implantation were retrospectively reviewed for reported brain injury (BI). Twelve patients (75%) had neuroimaging documented BI at some point in their life (i.e., before, during, or after VAD support). Five patients (31%) had neuroimaging evidence of acute BI incurred while on the VAD. The high overall number of patients with neuroimaging documented BI at any point in their life illustrates that the risk for BI also exists outside the window of VAD support. Patients with abnormal neurologic physical examination at follow-up had lower IQ and ABAS-II scores compared with patients with normal neurologic physical examination (mean full-scale IQ 66.9 vs. 95.0, p = 0.001; mean ABAS-II 66.3 vs. 94.2, p < 0.001).

Abstract
Adjusting to life after transplant can be challenging to pediatric solid organ transplant recipients and their families. In this review, we discuss a number of important factors to consider during the first 2-3 yr after transplant (defined as the "early years"), including transitioning from hospital to home, returning to physical activity, feeding and nutrition, school reentry, potential cognitive effects of transplant, family functioning, and QOL. We highlight steps that providers can take to optimize child and family adjustment during this period.

Abstract
This prospective inception cohort study determines kindergarten-entry neurocognitive abilities and explores their predictors following liver transplantation at age <3 yr. Of 52 children transplanted (1999-2008), 33 (89.2%) of 37 eligible survivors had psychological assessment at age 54.7 (8.4) months: 21 with biliary atresia, seven chronic cholestasis, and five acute liver failure. Neurocognitive scores (mean [s.d.], 100 [15]) as tested by a pediatric-experienced psychologist did not differ in relation to age group at transplant (≤12 months and >12 months): FSIQ, 93.9 (17.1); verbal (VIQ), 95.3 (16.5); performance (PIQ), 94.3 (18.1); and VMI, 90.5 (15.9), with >70% having scores ≥85, average or above. Adverse predictors from the pretransplant, transplant, and post-transplant (30 days) periods using univariate linear regressions for FSIQ were post-transplant use of inotropes, p = 0.029; longer transplant warm ischemia time, p = 0.035; and post-transplant highest serum creatinine, (p = 0.04). For PIQ, they were pretransplant encephalopathy, p = 0.027; post-transplant highest serum creatinine, p = 0.034; and post-transplant inotrope use, p = 0.037. For VMI, they were number of post-transplant infections, p = 0.019; post-transplant highest serum creatinine, p = 0.025; and lower family socioeconomic index, p = 0.039. Changes in care addressing modifiable predictors, including reducing acute post-transplant illness, pretransplant encephalopathy, transplant warm ischemia times, and preserving renal function, may improve neurocognitive outcomes.

Abstract
We reviewed reported survival and neurological outcomes, and predictors of these outcomes for pediatric cardiac extracorporeal membrane oxygenation (ECMO) and extracorporeal cardiopulmonary resuscitation (ECPR). We searched PubMed from 2000 to April 2011. Cumulative survival after cardiac ECMO in children was 788/1755 (45%); renal dysfunction, dialysis, neurologic complication, lactate, and ECMO duration consistently predicted this outcome, whereas single ventricle and ECPR did not. Neurological outcomes after cardiac ECMO were based on poorly described telephone questions in two studies for 47 patients with 51% significantly impaired and detailed follow-up testing for 42 patients in three studies with mental delay in 38% and mental score >85 (average or above) in 33%. Cumulative survival after ECPR in children was 371/762 (49%); noncardiac disease, renal dysfunction, neurologic complication, and pH on extracorporeal life support consistently predicted this outcome, whereas duration of CPR did not. Neurological outcomes after ECPR were based predominantly on the pediatric cerebral performance category (PCPC) score by chart review, with 161/181 (79%) having PCPC <2. No study reported detailed follow-up testing for survivors of ECPR. Survival outcomes of most cardiac subgroups were similar, except for concerning mortality in cavopulmonary connection patients. Priority areas for study include identification of potentially modifiable predictors of long-term outcomes.

Abstract
Data collection and dissemination have been a part of the US transplant experience since its earliest days. As part of this process, the United Network for Organ Sharing (UNOS) has provided open access to its data. In addition, multiinstitutional groups such as the Pediatric Heart Transplant Study (PHTS) have collected data of particular interest to pediatric and congenital transplants. This wealth of data enables quality improvement along several pathways including individual program assessment and improvement and development of both structure and process measures for ongoing improvement. Extensive literature exists utilizing these data, but must be read critically, recognizing the limitations presented by missing variables (whether uncollected or collected but left blank), reproducibility, and small sample sizes among pediatric patients. However, despite these limitations, opportunity continues to exist to apply these data sets to ongoing questions of quality and optimize organ allocation and long-term survival among pediatric patients with heart failure.

Abstract
Newly emerging health technologies are being developed to care for children with complex cardiac defects. Neurodevelopmental and childhood school-related outcomes are of great interest to parents of children receiving this care, care providers, and healthcare administrators. Since the 1970s, neonatal follow-up clinics have provided service, audit, and research for preterm infants as care for these at-risk children evolved. We have chosen to present for this issue the mechanism for longitudinal follow-up of survivors that we have developed for western Canada patterned after neonatal follow-up. Our program provides registration for young children receiving complex cardiac surgery, heart transplantation, ventricular assist device support, and extracorporeal life support among others. The program includes multidisciplinary assessments with appropriate neurodevelopmental intervention, active quality improvement evaluations, and outcomes research. Through this mechanism, consistently high (96%) follow-up over two years is maintained.
