RESUMEN
Several studies have suggested an inverse relationship between lower socioeconomic status (SES) and the incidence of congenital heart disease (CHD) among live births. We sought to examine this relationship further in a Canada-wide population study, exploring CHD subtypes, trends, and associated noncardiac abnormalities. Infants born in Canada (less Quebec) from 2008 to 2018 with CHD requiring intervention in the first year were identified using ICD-10 codes through the Canadian Institute for Health Information Discharge Abstract Database. Births of CHD patients were stratified by SES (census-based income quintiles) and compared against national birth proportions using X2 tests. Proportions with extracardiac defects (ED) and nonlethal genetic syndromes (GS) were also explored. From 2008 to 2018, 7711 infants born with CHD were included. The proportions of major CHD distributed across SES quintiles were 27.1%, 20.1%, 19.2%, 18.6%, and 15.0% from lowest to highest, with significant differences relative to national birth proportions (22.0%, 20.0%, 20.6%, 20.7%, and 16.7% from lowest (1) to highest (5)) (p < 0.0001). No temporal trends in the CHD proportions across SES categories were observed over the study period. The distribution across SES quintiles was different only for specific CHD subtypes (double-outlet right ventricle (n = 485, p = 0.03), hypoplastic left heart syndrome (n = 547, p = 0.006), heterotaxy (n = 224, p = 0.03), tetralogy of Fallot (n = 1007, p = 0.008), truncus arteriosus (n = 126, p < 0.0001), and ventricular septal defect (n = 1916, p < 0.0001)), with highest proportions observed in the lowest quintile. The proportion of the total population with ED but not GS was highest in lower SES quintiles (< 0.0001) commensurate with increased proportion of CHD. Our study suggests a negative association between SES and certain CHD lesions and ED.

PURPOSE: The objective of this study was to investigate the experience of first- and second- generation immigrant youth living with chronic health conditions in Canada, their parents or caregivers, and healthcare and service providers who care for immigrant youth, regarding the transition from pediatric to adult healthcare. DESIGN AND METHODS: We conducted semi-structured individual interviews and focus groups. Youth were 1st or 2nd generation immigrants, aged 16-25, with pediatric-onset chronic health conditions. Parents or caregivers had raised youth children as described. Providers delivered healthcare or other services to immigrant populations. Thematic analysis was conducted of all transcripts. RESULTS: Twenty youth, 14 parents/caregivers and five service providers participated. Most participants described healthcare transition as very difficult to navigate. Two major themes emerged across participant narratives: 1. Barriers to transition: lack of family experience in Canada, language, discrimination, financial strain, stigma, and long wait times. Some of these barriers are specific to newcomer families, but others are generalizable to the Canadian population. 2. Facilitators of transition: youth independence, youth acting as cultural bridges within their families, and cross-sector support between healthcare, education, social work and settlement services. CONCLUSIONS: Immigrant youth and their families face a broad range of barriers to healthcare transition. The collaborative nature of cross-sector support effectively addressed some of the barriers faced by newcomer families. PRACTICE IMPLICATIONS: Clinicians should provide immigrant youth and their families with accessible information about the health condition and how to navigate the adult healthcare system prior to transition, particularly when language barriers exist.

BACKGROUND: A large proportion of youth with chronic conditions have mental health comorbidities. However, the effect of these comorbidities on paediatric-adult transition readiness, and the relevance of widely used tools for measuring transition readiness, are unknown. OBJECTIVE: The objectives of this study were to describe and explore the transition readiness of youth with co-occurring chronic health and mental health conditions using a combination of quantitative data obtained from participants completing the Transition Readiness Assessment Questionnaire (TRAQ) and qualitative data. DESIGN AND PARTICIPANTS: A three-phase sequential explanatory mixed methods design was employed, with the qualitative strand taking priority. First, the TRAQ scores (range 1-5) of youth with co-occurring conditions (n = 61) enroled in a multisite randomized controlled trial were measured, followed by qualitative interviews with a sample of youth (n = 9) to explain the quantitative results. Results from both strands were then integrated, yielding comprehensive insights. RESULTS: Median TRAQ scores ranged from 2.86 on the appointment keeping subscale to 5.00 on the talking with providers subscale. The qualitative results uncovered the complexities faced by this group concerning the impact of a mental health comorbidity on transition readiness and self-management skills across TRAQ domains. The integrated findings identified a diverse and highly individualized set of strengths and challenges amongst this group that did not align with overarching patterns as measured by the TRAQ. CONCLUSIONS: This mixed methods study generated novel understandings about how youth with co-occurring conditions develop competencies related to self-care, self-advocacy and self-management in preparation for paediatric-adult service transitions. Results demonstrated the assessment of transition readiness using a generic scale does not address the nuanced and complex needs of youth with co-occurring chronic health and mental health conditions. Our findings suggest tailoring transition readiness practices for this group based on youths' own goals, symptoms, coping mechanisms and resources. PATIENT OR PUBLIC INVOLVEMENT: This study was conducted in collaboration with five young adult research partners (YARP) with lived experience transitioning from paediatric to adult health/mental health services. The YARP's contributions across study phases ensured the perspectives of young people were centred throughout data collection, analysis, interpretation and presentation of findings. All five YARP co-authored this manuscript.

BACKGROUND: Transition-age youth (TAY) with chronic health conditions frequently experience co-occurring mental health conditions. However, little is known about the perspectives of TAY with co-occurring diagnoses preparing to exit pediatric health and mental health services. Research is needed to understand the impact of a mental health condition on transition readiness and self-management in TAY with chronic health conditions. METHODS: TAY (aged 16-20 years) with co-occurring chronic health and mental health conditions were recruited in Alberta, Canada. Nine semi-structured individual interviews were completed by phone or videoconference, and transcribed verbatim. Guided by qualitative description, we analyzed the data using thematic analysis in partnership with five young adults with lived experience in the health/mental health systems. RESULTS: Participants shared their experiences living with simultaneous physical and mental health concerns and preparing for transition to adult care. Our analysis revealed three overarching themes: 1) "they're intertwined": connections between chronic health and mental health conditions in TAY, 2) impact of mental health on transition readiness and self-management, and 3) recommendations for service provision from the perspectives of TAY. CONCLUSIONS: Our findings highlighted the myriad ways in which physical and mental health are connected as TAY prepare for service transitions using specific examples and powerful metaphors. TAY endorsed the importance of providers discussing these connections in routine clinical care. Future research should involve co-designing and evaluating educational material addressing this topic with diverse TAY, caregivers, and service providers.

Indications for the closure of pressure restrictive perimembranous ventricular septal defects (pmVSD) are not well established in the pediatric population. We sought to assess practice variability among pediatric cardiologists in the United States (US), Canada, Australia, and New Zealand. A survey ascertaining practice patterns, including case vignettes with incremental progression of disease severity, was designed and administered through representative professional cardiac organizations and email listservs in the designated countries. Among the 299 respondents, 209 (70.0%) were from the US, 65 (21.7%) were from Canada and 25 (8.3%) were from Australia and New Zealand. Indications for pressure restrictive pmVSD closure included the presence of left ventricular (LV) dilation for 81.6% (244/299) (defined as z-score ≥ 2 for 59.0% (144/244) and ≥ 3 for 40.2% (98/244)) and significant pulmonary-systemic flow ratio (QP:QS) for 71.2% (213/299) [defined as ≥ 1.5:1 for 36.2% (77/213) and ≥ 2 for 62% (132/213)]. US pediatric cardiologists elected to close restrictive pmVSD at lower LV z-score and QP:QS ratio cut-offs (p-value 0.0002 and 0.013, respectively). In a case vignette, 63.6% (173/272) chose to intervene if there was right coronary cusp prolapse with stable mild aortic regurgitation. Of the remaining cardiologists, 93% (92/99) intervened if the aortic regurgitation was progressive (from trivial to mild). Commonly identified indications with variable thresholds for closure of pressure restrictive pmVSDs included the presence or progression of LV dilation, significant volume loading, and aortic valve prolapse with regurgitation. US pediatric cardiologists may have a lower threshold for pmVSD closure.

The Pediatric Heart Network's Fontan Udenafil Exercise Longitudinal (FUEL) Trial (Mezzion Pharma Co. Ltd., NCT02741115) demonstrated improvements in some measures of exercise capacity and in the myocardial performance index following 6 months of treatment with udenafil (87.5 mg twice daily). In this post hoc analysis, we evaluate whether subgroups within the population experienced a differential effect on exercise performance in response to treatment. The effect of udenafil on exercise was evaluated within subgroups defined by baseline characteristics, including peak oxygen consumption (VO2), serum brain-type natriuretic peptide level, weight, race, gender, and ventricular morphology. Differences among subgroups were evaluated using ANCOVA modeling with fixed factors for treatment arm and subgroup and the interaction between treatment arm and subgroup. Within-subgroup analyses demonstrated trends toward quantitative improvements in peak VO2, work rate at the ventilatory anaerobic threshold (VAT), VO2 at VAT, and ventilatory efficiency (VE/VCO2) for those randomized to udenafil compared to placebo in nearly all subgroups. There was no identified differential response to udenafil based on baseline peak VO2, baseline BNP level, weight, race and ethnicity, gender, or ventricular morphology, although participants in the lowest tertile of baseline peak VO2 trended toward larger improvements. The absence of a differential response across subgroups in response to treatment with udenafil suggests that the treatment benefit may not be restricted to specific sub-populations. Further work is warranted to confirm the potential benefit of udenafil and to evaluate the long-term tolerability and safety of treatment and to determine the impact of udenafil on the development of other morbidities related to the Fontan circulation.Trial Registration NCT0274115.

INTRODUCTION: Over 90% of children with CHD survive into adulthood and require lifelong cardiology care. Delays in care predispose patients to cardiac complications. We sought to determine the time interval to accessing adult CHD care beyond what was recommended by the referring paediatric cardiologist (excess time) and determine risk factors for prolonged excess time. MATERIALS AND METHODS: Retrospective cohort study including all patients in the province of Alberta, Canada, age 16-18 years at their last paediatric cardiology visit, with moderate or complex lesions. Excess time between paediatric and adult care was defined as the interval (months) between the final paediatric visit and the first adult visit, minus the recommended interval between these appointments. Patients whose first adult CHD appointment occurred earlier than the recommended interval were assigned an excess time of zero. RESULTS: We included 286 patients (66% male, mean age 17.6 years). Mean excess time was 7.9 ± 15.9 months. Twenty-nine (10%) had an excess time > 24 months. Not having a pacemaker (p = 0.03) and not needing cardiac medications at transfer (p = 0.02) were risk factors for excess time >3 months. Excess time was not influenced by CHD complexity. DISCUSSION: The mean delay to first adult CHD appointment was almost 8 months longer than recommended by referring paediatric cardiologists. Not having a pacemaker and not needing cardiac medication(s) were risk factors for excess time > 3 months. Greater outpatient resources are required to accommodate the growing number of adult CHD survivors.
RESUMEN
OBJECTIVE: To evaluate the impact of a novel nurse-led transition intervention program designed for young adolescents (age 13-14 years) with congenital heart disease (CHD). We hypothesized that the intervention would result in improved self-management skills and CHD knowledge. STUDY DESIGN: Single-center cluster randomized controlled trial of a nurse-led transition intervention vs usual care. The intervention group received a 1-hour individualized session with a cardiology nurse, focusing on CHD education and self-management. The primary end point was change in TRANSITION-Q (transition readiness) score between baseline and 6 months. The secondary end point was change in MyHeart score (CHD knowledge). RESULTS: We randomized 60 participants to intervention (n = 30) or usual care (n = 30). TRANSITION-Q score (range 0-100) increased from 49 ± 10 at baseline to 54 ± 9.0 at 6 months (intervention) vs 47 ± 14 to 44 ± 14 (usual care). Adjusted for baseline score, TRANSITION-Q scores at 1 and 6 months were greater in the intervention group (mean difference 5.9, 95% CI 1.3-10.5, P = .01). MyHeart score (range 0-100) increased from 48 ± 24 at baseline to 71 ± 16 at 6 months (intervention) vs 54 ± 24 to 57 ± 22 (usual care). Adjusted for baseline score, MyHeart scores at 1 and 6 months were greater in the intervention group (mean difference 19, 95% CI 12-26, P < .0001). Participants aged 14 years had a greater increase in TRANSITION-Q score at 6 months compared with 13-year-old participants (P < .05). CONCLUSIONS: A nurse-led program improved transition readiness and CHD knowledge among young adolescents. This simple intervention can be readily adopted in other healthcare settings. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02374892.

OBJECTIVE: To evaluate practice variation in pharmacologic management in the International Kawasaki Disease Registry (IKDR). STUDY DESIGN: Practice variation in intravenous immunoglobulin (IVIG) therapy, anti-inflammatory agents, statins, beta-blockers, antiplatelet therapy, and anticoagulation was described. RESULTS: We included 1627 patients from 30 IKDR centers with maximum coronary artery aneurysm (CAA) z scores 2.5-4.99 in 848, 5.0-9.99 in 349, and ≥10.0 (large/giant) in 430 patients. All centers reported IVIG and acetylsalicylic acid (ASA) as primary therapy and use of additional IVIG or steroids as needed. In 23 out of 30 centers, (77%) infliximab was also used; 11 of these 23 centers reported using it in <10% of their patients, and 3 centers used it in >20% of patients. Nonsteroidal anti-inflammatory agents were used in >10% of patients in only nine centers. Beta-blocker (8.8%, all patients) and abciximab (3.6%, all patients) were mainly prescribed in patients with large/giant CAAs. Statins (2.7%, all patients) were mostly used in one center and only in patients with large/giant CAAs. ASA was the primary antiplatelet modality for 99% of patients, used in all centers. Clopidogrel (18%, all patients) was used in 24 centers, 11 of which used it in >50% of their patients with large/giant CAAs. CONCLUSIONS: In the IKDR, IVIG and ASA therapy as primary therapy is universal with common use of a second dose of IVIG for persistent fever. There is practice variation among centers for adjunctive therapies and anticoagulation strategies, likely reflecting ongoing knowledge gaps. Randomized controlled trials nested in a high-quality collaborative registry may be an efficient strategy to reduce practice variation.

PURPOSE: Between 33 and 59% of youth with chronic health conditions experience mental health conditions. Transition readiness, or the acquisition of knowledge and self-management skills, facilitates successful transition to adult care. Transition readiness among youth with co-occurring chronic health and mental health conditions has not been explored. DESIGN AND METHODS: This study used a sample of 201 patients (aged 16-21) with chronic conditions. All patients completed the Transition Readiness Assessment Questionniare (TRAQ) and were grouped into Cohort A: chronic health conditions only (n = 140), and Cohort B: co-occurring chronic health and mental health conditions (n = 61). A quantile regression at the 50th percentile was conducted to examine associations between TRAQ score and mental health comorbidity, age, gender and immigration status. RESULTS: The median TRAQ score for Cohort A was 3.87 (IQR 0.84) versus 4.00 (IQR 0.87) for Cohort B. Our analysis revealed that having a mental health comorbidity (b = 0.402, p = 0.034), being older in age (b = 0.540, p = 0.004) and being female (b = 0.388, p = 0.001) were associated with higher overall TRAQ score. CONCLUSIONS: The presence of a mental health comorbidity was associated with greater transition readiness as measured by the TRAQ in our sample. Future research should explore why youth with co-occurring chronic health and mental health conditions exhibit greater transition readiness. PRACTICE IMPLICATIONS: Youth with co-occurring chronic health and mental health conditions may develop transition readiness as a result of coping with mental health challenges. Practitioners could invite them to reflect on how their physical and mental health are related and affect their level of preparedness for adult care.

OBJECTIVE: To understand use of family physician services and emergency department visits by adolescents and young adults with chronic health conditions. DESIGN: Longitudinal retrospective observational cohort study using administrative health data. SETTING: Chronic care clinics at a tertiary care pediatric hospital in Calgary, Alta. PARTICIPANTS: In total, 1326 adolescents who were between 12 and 15 years old in 2008, who were observed until 2016, and who received medical services for chronic conditions were enrolled in the study. Eligible participants had at least 4 visits to the same chronic disease clinic in any 2-year window before age 18. MAIN OUTCOMES MEASURES: Group-based trajectory modeling was used to identify groups of adolescents with distinct patterns of health care use (for visits to emergency departments and to primary care practices), while 2 tests explored trajectory group differences (eg, sex, location of residence). RESULTS: Median age was 14 years (range 12 to 17 years) at study entry, and 22 years (range 14 to 24 years) at study exit. Half were female and most (85.4%) lived in an urban area. Median observation period was 8.7 person-years (range 1.3 to 9.1 years). Group-based trajectory modeling identified 5 distinct trajectory groups of primary care use and 4 groups of emergency services use. Groups differed by sex and location of residence in each trajectory model. CONCLUSION: Many adolescents increased their use of emergency services between the ages of 12 and 24 years, with distinct patterns of primary care use being observed. Association of additional patient- and system-level factors (eg, disease severity, distance to nearest family physician office) should be explored.

BACKGROUND: The Fontan operation creates a total cavopulmonary connection, a circulation in which the importance of pulmonary vascular resistance is magnified. Over time, this circulation leads to deterioration of cardiovascular efficiency associated with a decline in exercise performance. Rigorous clinical trials aimed at improving physiology and guiding pharmacotherapy are lacking. METHODS: The FUEL trial (Fontan Udenafil Exercise Longitudinal) was a phase III clinical trial conducted at 30 centers. Participants were randomly assigned udenafil, 87.5 mg twice daily, or placebo in a 1:1 ratio. The primary outcome was the between-group difference in change in oxygen consumption at peak exercise. Secondary outcomes included between-group differences in changes in submaximal exercise at the ventilatory anaerobic threshold, the myocardial performance index, the natural log of the reactive hyperemia index, and serum brain-type natriuretic peptide. RESULTS: Between 2017 and 2019, 30 clinical sites in North America and the Republic of Korea randomly assigned 400 participants with Fontan physiology. The mean age at randomization was 15.5±2 years; 60% of participants were male, and 81% were white. All 400 participants were included in the primary analysis with imputation of the 26-week end point for 21 participants with missing data (11 randomly assigned to udenafil and 10 to placebo). Among randomly assigned participants, peak oxygen consumption increased by 44±245 mL/min (2.8%) in the udenafil group and declined by 3.7±228 mL/min (-0.2%) in the placebo group (P=0.071). Analysis at ventilatory anaerobic threshold demonstrated improvements in the udenafil group versus the placebo group in oxygen consumption (+33±185 [3.2%] versus -9±193 [-0.9%] mL/min, P=0.012), ventilatory equivalents of carbon dioxide (-0.8 versus -0.06, P=0.014), and work rate (+3.8 versus +0.34 W, P=0.021). There was no difference in change of myocardial performance index, the natural log of the reactive hyperemia index, or serum brain-type natriuretic peptide level. CONCLUSIONS: In the FUEL trial, treatment with udenafil (87.5 mg twice daily) was not associated with an improvement in oxygen consumption at peak exercise but was associated with improvements in multiple measures of exercise performance at the ventilatory anaerobic threshold.

OBJECTIVE: To derive cluster analysis-based groupings for adults with congenital heart disease (ACHD) when it comes to perceived health, psychological functioning, health behaviours and quality of life (QoL). METHODS: This study was part of a larger worldwide multicentre study called APPROACH-IS; a cross sectional study which recruited 4028 patients (2013-2015) from 15 participating countries. A hierarchical cluster analysis was performed using Ward's method in order to group patients with similar psychological characteristics, which were defined by taking into consideration the scores of the following tests: Sense Of Coherence, Health Behavior Scale (physical exercise score), Hospital Anxiety Depression Scale, Illness Perception Questionnaire, Satisfaction with Life Scale and the Visual Analogue Scale scores of the EQ-5D perceived health scale and a linear analogue scale (0-100) measuring QoL. RESULTS: 3768 patients with complete data were divided into 3 clusters. The first and second clusters represented 89.6% of patients in the analysis who reported a good health perception, QoL, psychological functioning and the greatest amount of exercise. Patients in the third cluster reported substantially lower scores in all PROs. This cluster was characterised by a significantly higher proportion of females, a higher average age the lowest education level, more complex forms of congenital heart disease and more medical comorbidities. CONCLUSIONS: This study suggests that certain demographic and clinical characteristics may be linked to less favourable health perception, quality of life, psychological functioning, and health behaviours in ACHD. This information may be used to improve psychosocial screening and the timely provision of psychosocial care.

Pericardial effusion (PE) after cardiac surgery can be life threatening without timely detection, and the optimal screening method is unknown. We sought to evaluate the role of a surveillance echocardiogram on postoperative day 10 (± 2), determine the incidence of postoperative PE, and identify risk factors. We conducted a retrospective cohort study including all pediatric patients who underwent open heart surgery at a single institution over a 7-month period. To identify risk factors for PE, medical records of patients with PE detected within 6 weeks after surgery (cases) were compared with patients without PE (controls). Of 203 patients, 52 (26%) had PE within 6 weeks; 42 (81%) were trivial-small and 10 (19%) were moderate-large. Twenty-nine (56%) were first detected within 7 days post-operatively, including all cases developing cardiac tamponade (n = 3). An echocardiogram was done 10 (± 2) days post-operatively in 41/52 cases, of which 12/41 (29%) did not have a PE at this time, 24/41 (59%) had a trivial-small PE, and 5/41(12%) had a moderate-large PE; 2 of the latter had no prior detected PE. Closure of an atrial septal defect had the highest incidence of PE (42%). PE cases were associated with postoperative nasopharyngeal detection of a respiratory virus (OR 3.8, p = 0.03). In conclusion, the majority of PE cases were detected within 7 days post-operatively, including all cases subsequently developing cardiac tamponade. Day 10 echocardiography infrequently detected a moderate or large effusion that had previously gone undiagnosed. A positive perioperative nasopharyngeal aspirate for a respiratory virus was associated with postoperative PE.

In the 2017 American Heart Association (AHA) Kawasaki disease (KD) guidelines, risk levels (RLs) for long-term management are defined by both maximal and current coronary artery (CA) dimensions normalized as z-scores. We sought to determine the degree to which current recommended practice differs from past actual practice, highlighting areas for knowledge translation efforts. The International KD Registry (IKDR) included 1651 patients with CA aneurysms (z-score > 2.5) from 1999 to 2016. Patients were classified by AHA RL using maximum CA z-score (RL 3 = small, RL 4 = medium, RL 5 = large/giant) and subcategorized based on decreases over time. Medical management provided was compared to recommendations. Low-dose acetylsalicylic acid (ASA) use ranged from 86 (RL 3.1) to 95% (RL 5.1) for RLs where use was "indicated." Dual antiplatelet therapy (ASA + clopidogrel) use ranged from 16% for RL 5.2 to 9% for RL 5.4. Recommended anticoagulation (warfarin or low molecular weight heparin) use was 65% for RL 5.1, while 12% were on triple therapy (anticoagulation + dual antiplatelet). Optional statin use ranged from 2 to 8% depending on RL. Optional beta-blocker use was 2-25% for RL 5, and 0-5% for RLs 3 and 4 where it is not recommended. Generally, past practice was consistent with the latest AHA guidelines, taking into account the flexible wording of recommendations based on the limited evidence, as well as unmeasured patient-specific factors. In addition to strengthening the overall evidence base, knowledge translation efforts may be needed to address variation in thromboprophylaxis management.

INTRODUCTION: Preliminary animal and human data suggest that angiotensin-converting enzyme inhibition has a role in pulmonary vascular remodelling. We sought to assess the effect of ACEi versus placebo on pulmonary artery pressure and transpulmonary gradient amongst infants undergoing single-ventricle palliation. MATERIALS AND METHODS: Using the publicly available Pediatric Heart Network Infant Single-Ventricle trial dataset, we compared mean PA pressure at pre-superior cavopulmonary connection catheterisation (primary outcome), transpulmonary gradient, pulmonary-to-systemic flow ratio, and post-SCPC oxygen saturation (secondary outcomes) in infants receiving enalapril versus placebo. RESULTS: A total of 179 infants underwent pre-SCPC catheterisation, of which 85 (47%) received enalapril. There was no difference between the enalapril and placebo group in the primary and the secondary outcomes. Mean PA pressure in the enalapril group was 13.1 ± 2.9 compared to 13.7 ± 3.4 mmHg in the placebo group. The transpulmonary gradient was 6.7 ± 2.5 versus 6.9 ± 3.2 mmHg in the enalapril and placebo groups, respectively. The pulmonary-to-systemic flow ratio was 1.1 ± 0.5 in the enalapril group versus 1.0 ± 0.5 in the placebo group and the post-SCPC saturation was 83.1 ± 5.0% in the enalapril group versus 82.2 ± 5.3% in the placebo group. In the pre-specified subgroup analyses comparing enalapril and placebo according to ventricular morphology and shunt type, there was no difference in the primary and secondary outcomes. CONCLUSION: ACEi did not impact mean pulmonary artery pressure or transpulmonary gradient amongst infants with single-ventricle physiology prior to SCPC palliation.

PURPOSE: To understand the effectiveness of a nurse-led transition intervention by analyzing qualitative data generated in the context of a clinical trial. DESIGN & METHODS: Qualitative study of a two-session transition intervention conducted by registered nurses at two sites. Adolescents aged 16-17 years with moderate or complex congenital heart disease (CHD) had been randomized to a two-session transition intervention or usual care. Session 1 emphasized patient education including creation of a health passport and goal setting. Session 2, two months later, emphasized self-management. Qualitative data extracted from intervention logs, field notes and audio recordings of the sessions were analyzed for content and themes. RESULTS: Data from 111 transition intervention sessions with 57 adolescents were analyzed. Creating a health passport, goal setting, and role-plays were the elements of the intervention most valued by participants. A typology of transition readiness was identified: 1) the independent adolescent (5%), already managing their own care; 2) the ready adolescent who was prepared for transition after completing the intervention (46%); 3) the follow-up needed adolescent who was still in need of extra coaching (26%), and 4) the at-risk adolescent who warranted immediate follow-up (14%). Baseline knowledge and transition surveys scores validated the typology. CONCLUSIONS: A two-session nursing intervention met the transition needs of approximately half of adolescents with CHD. However, additional transition-focused care was needed by 40% of participants (groups 3 and 4). PRACTICE IMPLICATIONS: These findings will guide pediatric nurses and other healthcare professionals to optimize an individualized approach for ensuring transition readiness for adolescents with CHD.

BACKGROUND: The relationship between healthcare system inputs (e.g., human resources and infrastructure) and mortality has been extensively studied. However, the association between healthcare system inputs and patient-reported outcomes remains unclear. Hence, we explored the predictive value of human resources and infrastructures of the countries' healthcare system on patient-reported outcomes in adults with congenital heart disease. METHODS: This cross-sectional study included 3588 patients with congenital heart disease (median age = 31y; IQR = 16.0; 52% women; 26% simple, 49% moderate, and 25% complex defects) from 15 countries. The following patient-reported outcomes were measured: perceived physical and mental health, psychological distress, health behaviors, and quality of life. The assessed inputs of the healthcare system were: (i) human resources (i.e., density of physicians and nurses, both per 1000 people) and (ii) infrastructure (i.e., density of hospital beds per 10,000 people). Univariable, multivariable, and sensitivity analyses using general linear mixed models were conducted, adjusting for patient-specific variables and unmeasured country differences. RESULTS: Sensitivity analyses showed that higher density of physicians was significantly associated with better self-reported physical and mental health, less psychological distress, and better quality of life. A greater number of nurses was significantly associated with better self-reported physical health, less psychological distress, and less risky health behavior. No associations between a higher density of hospital beds and patient-reported outcomes were observed. CONCLUSIONS: This explorative study suggests that density of human resources for health, measured on country level, are associated with patient-reported outcomes in adults with congenital heart disease. More research needs to be conducted before firm conclusions about the relationships observed can be drawn. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02150603. Registered 30 May 2014.

INTRODUCTION: We evaluated the safety and feasibility of high-intensity interval training via a novel telemedicine ergometer (MedBIKE™) in children with Fontan physiology. METHODS: The MedBIKE™ is a custom telemedicine ergometer, incorporating a video game platform and live feed of patient video/audio, electrocardiography, pulse oximetry, and power output, for remote medical supervision and modulation of work. There were three study phases: (I) exercise workload comparison between the MedBIKE™ and a standard cardiopulmonary exercise ergometer in 10 healthy adults. (II) In-hospital safety, feasibility, and user experience (via questionnaire) assessment of a MedBIKE™ high-intensity interval training protocol in children with Fontan physiology. (III) Eight-week home-based high-intensity interval trial programme in two participants with Fontan physiology. RESULTS: There was good agreement in oxygen consumption during graded exercise at matched work rates between the cardiopulmonary exercise ergometer and MedBIKE™ (1.1 ± 0.5 L/minute versus 1.1 ± 0.5 L/minute, p = 0.44). Ten youth with Fontan physiology (11.5 ± 1.8 years old) completed a MedBIKE™ high-intensity interval training session with no adverse events. The participants found the MedBIKE™ to be enjoyable and easy to navigate. In two participants, the 8-week home-based protocol was tolerated well with completion of 23/24 (96%) and 24/24 (100%) of sessions, respectively, and no adverse events across the 47 sessions in total. CONCLUSION: The MedBIKE™ resulted in similar physiological responses as compared to a cardiopulmonary exercise test ergometer and the high-intensity interval training protocol was safe, feasible, and enjoyable in youth with Fontan physiology. A randomised-controlled trial of a home-based high-intensity interval training exercise intervention using the MedBIKE™ will next be undertaken.

Post-operative length of stay (LOS) is an important metric for both healthcare providers and patients and their families. Predicting LOS is a challenge as it is sensitive to multitudinous patient and system factors. All subjects undergoing a Fontan from 1996-2016 who survived to hospital discharge were included. Details about the pre-operative status, operative conduct, and post-operative course of each patient were obtained. The association between patient characteristics and post-Fontan LOS were determined using stepwise multivariable regression models. Of 320 subjects who underwent a Fontan, 314 (98.1%) survived to hospital discharge. Median age at Fontan was 3.3 years (IQR 2.8, 4.0) and the most common underlying diagnosis was hypoplastic left heart syndrome (106, 33.8%). Median post Fontan LOS was 11 days (IQR 8, 17). Univariable risk factors for longer LOS included number of previous surgeries, post-Glenn LOS, cardiopulmonary bypass time, post-operative chylothorax, and failure to extubate in the operating room (all p < 0.05). In multivariable models, number of previous operations, extubation in the operating room, and postoperative complications predicted LOS (R2 = 0.5185 for full model). The proportion of patients discharged on week days (14.7-18.8% per day) was significantly higher than the proportion discharged on weekend days (5.1-9.9% per weekend day). Pre-operative variables have limited use in predicting post-Fontan length of stay. The most important predictors of post-operative LOS are extubation in the operating room and the occurrence of post-operative complications. However, a significant proportion of variability in LOS was not explained by available measurable variables.
