Translating Precision Health for Pediatrics: A Scoping Review.

Precision health aims to personalize treatment and prevention strategies based on individual genetic differences. While it has significantly improved healthcare for specific patient groups, broader translation faces challenges with evidence development, evidence appraisal, and implementation. These challenges are compounded in child health as existing methods fail to incorporate the physiology and socio-biology unique to childhood. This scoping review synthesizes the existing literature on evidence development, appraisal, prioritization, and implementation of precision child health. PubMed, Scopus, Web of Science, and Embase were searched. The included articles were related to pediatrics, precision health, and the translational pathway. Articles were excluded if they were too narrow in scope. In total, 74 articles identified challenges and solutions for putting pediatric precision health interventions into practice. The literature reinforced the unique attributes of children and their implications for study design and identified major themes for the value assessment of precision health interventions for children, including clinical benefit, cost-effectiveness, stakeholder values and preferences, and ethics and equity. Tackling these identified challenges will require developing international data networks and guidelines, re-thinking methods for value assessment, and broadening stakeholder support for the effective implementation of precision health within healthcare organizations. This research was funded by the SickKids Precision Child Health Catalyst Grant.

The Experience of Parental Caregiving for Children With Medical Complexity.

Children with medical complexity (CMC) have complex chronic conditions with significant functional impairment, contributing to high caregiving demand. This study seeks to explore impacts of parental caregiving for CMC. Fifteen caregivers of CMC followed at a tertiary care hospital participated in semi-structured interviews. Interviews were concurrently analyzed using a qualitative description framework until thematic saturation was reached. Codes were grouped by shared concepts to clarify emergent findings. Four affected domains of parental caregiver experience with associated subthemes (in parentheses) were identified: personal (identity, physical health, mental health), family (marriage, siblings, family quality of life), social (time limitations, isolating lived experience), and financial (employment, medical costs, accessibility costs). Despite substantial challenges, caregivers identified two core determinants of personal resilience: others' support (hands-on, interpersonal, informational, material) and a positive outlook (self-efficacy, self-compassion, reframing expectations). Further research is needed to understand the unique needs and strengths of caregivers for this vulnerable population.

The Experience of Housing Needs Among Families Caring for Children With Medical Complexity.

BACKGROUND AND OBJECTIVES: Caregivers of children with medical complexity (CMC) face many stressors related to their child's medical condition(s). Financial stress and its impact on housing has been reported to be a challenge among this population. However, unique housing challenges specific to CMC, including disability accommodations in the home and housing space and layout, have yet to be examined in the literature. METHODS: We conducted 20 individual semistructured interviews with parents of CMC. Interviews were recorded, coded, and analyzed by using thematic analysis to emphasize, examine, and record patterns of meaning within the data. RESULTS: Eighteen mothers and 2 fathers participated in individual interviews. Two major themes and subthemes (in parentheses) were identified: (1) the impact of health on housing (housing preferences, housing possibilities, and housing outcome as a trade-off) and (2) the impact of housing on health (health of the caregiver and health of the child). Parents had preferences regarding the location and layout of their home specific to their child's illness and medical needs. In addition, parents indicated their child's illness affected their income and home ownership status, which in turn shaped their housing possibilities. The location and layout of the family home was often the result of a trade-off between the caregiver's housing preferences and possibilities. CONCLUSIONS: Housing outcomes among CMC are often the result of a trade-off between housing preferences and possibilities, both of which are influenced by the child's health status. Policy changes targeting housing accessibility and affordability are vital to support the health of CMC.

Genome Sequencing as a Diagnostic Test in Children With Unexplained Medical Complexity.

Importance: Children with medical complexity (CMC) represent a growing population in the pediatric health care system, with high resource use and associated health care costs. A genetic diagnosis can inform prognosis, anticipatory care, management, and reproductive planning. Conventional genetic testing strategies for CMC are often costly, time consuming, and ultimately unsuccessful. Objective: To evaluate the analytical and clinical validity of genome sequencing as a comprehensive diagnostic genetic test for CMC. Design, Setting, and Participants: In this cohort study of the prospective use of genome sequencing and comparison with standard-of-care genetic testing, CMC were recruited from May 1, 2017, to November 30, 2018, from a structured complex care program based at a tertiary care pediatric hospital in Toronto, Canada. Recruited CMC had at least 1 chronic condition, technology dependence (child is dependent at least part of each day on mechanical ventilators, and/or child requires prolonged intravenous administration of nutritional substances or drugs, and/or child is expected to have prolonged dependence on other device-based support), multiple subspecialist involvement, and substantial health care use. Review of the care plans for 545 CMC identified 143 suspected of having an undiagnosed genetic condition. Fifty-four families met inclusion criteria and were interested in participating, and 49 completed the study. Probands, similarly affected siblings, and biological parents were eligible for genome sequencing. Exposures: Genome sequencing was performed using blood-derived DNA from probands and family members using established methods and a bioinformatics pipeline for clinical genome annotation. Main Outcomes and Measures: The primary study outcome was the diagnostic yield of genome sequencing (proportion of CMC for whom the test result yielded a new diagnosis). Results: Genome sequencing was performed for 138 individuals from 49 families of CMC (29 male and 20 female probands; mean [SD] age, 7.0 [4.5] years). Genome sequencing detected all genomic variation previously identified by conventional genetic testing. A total of 15 probands (30.6%; 95% CI 19.5%-44.6%) received a new primary molecular genetic diagnosis after genome sequencing. Three individuals had novel diseases and an additional 9 had either ultrarare genetic conditions or rare genetic conditions with atypical features. At least 11 families received diagnostic information that had clinical management implications beyond genetic and reproductive counseling. Conclusions and Relevance: This study suggests that genome sequencing has high analytical and clinical validity and can result in new diagnoses in CMC even in the setting of extensive prior investigations. This clinical population may be enriched for ultrarare and novel genetic disorders. Genome sequencing is a potentially first-tier genetic test for CMC.

Toward an Understanding of Advance Care Planning in Children With Medical Complexity.

BACKGROUND AND OBJECTIVES: Children with medical complexity (CMC) often have multiple life-limiting conditions with no unifying diagnosis and an unclear prognosis and are at high risk for morbidity and mortality. Advance care planning (ACP) conversations need to be uniquely tailored to this population. Our primary objective for this study was to develop an in-depth understanding of the ACP experiences from the perspectives of both parents and health care providers (HCPs) of CMC. METHODS: We conducted 25 semistructured interviews with parents of CMC and HCPs of various disciplines from a tertiary pediatric hospital. Interview guide questions were focused on ACP, including understanding of the definition, positive and negative experiences, and suggestions for improvement. Interviews were conducted until thematic saturation was reached. Interviews were audio recorded, transcribed verbatim, coded, and analyzed using content analysis. RESULTS: Fourteen mothers and 11 HCPs participated in individual interviews. Interviews revealed 4 major themes and several associated subthemes (in parentheses): (1) holistic mind-set, (2) discussion content (beliefs and values, hopes and goals, and quality of life), (3) communication enhancers (partnerships in shared decision-making, supportive setting, early and ongoing conversations, consistent language and practice, family readiness, provider expertise in ACP discussions, and provider comfort in ACP discussions), and (4) the ACP definition. CONCLUSIONS: Family and HCP perspectives revealed a need for family-centered ACP for CMC and their families. Our results aided the development of a family-centered framework to enhance the delivery of ACP through a holistic mind-set, thoughtful discussion content, and promoting of conversation enhancers.

Evaluating Curricular Modules in the Care of Children With Medical Complexity: A Mixed-Methods Randomized Controlled Trial.

OBJECTIVE: Children with medical complexity (CMC) are a growing population, yet training in complex care varies across pediatric residency programs. The purpose of this study was 1) to evaluate the effectiveness of a curriculum for pediatric residents in improving performance in a simulated clinical scenario, and 2) to explore residents' perceived self-efficacy in caring for CMC. METHODS: A randomized controlled trial was conducted supplemented by qualitative inquiry. Pediatric residents from 2 residency programs were randomly assigned to participate in interactive modules on: 1) clinical assessment, care planning, and technological dependency or 2) noncomplex care topics. The primary outcome was mean score on an Observed Structured Clinical Examination (OSCE) of tracheostomy care. Semistructured interviews were conducted postintervention and analyzed using qualitative content analysis. RESULTS: Ninety-four eligible residents were randomized. Residents who attended all modules and the OSCE and consented to participate (intervention [n = 20] and control [n=24]) were included in the final analysis. At baseline, few (9%) reported being comfortable caring for CMC. There was no significant difference in mean OSCE score between intervention and control groups (39.0 ± 1.1 vs 38.0 ± 1.0, P = .48). Qualitative analysis revealed 3 emerging themes related to resident self-efficacy: building a system of care, navigating uncertainty, and professional identity formation. CONCLUSIONS: A standardized complex care curriculum delivered in a classroom setting did not lead to improved performance in an OSCE station despite increased resident-reported self-efficacy in approaching care for CMC. These findings highlight the need for multidimensional educational interventions and assessments in complex care.

A Systematic Review of Fatigue in Radiology: Is It a Problem?

OBJECTIVE: The purpose of this study was to review current literature regarding radiologist fatigue. MATERIALS AND METHODS: A literature search was performed using PubMed. Key words and Medical Subject Heading terms were used to generate refined queries with inclusion and exclusion criteria, focusing on fatigue and error. Results were selected according to these criteria: examined radiologist fatigue and radiologic error stemming from fatigue; experimental results measured as accuracy, error, or performance; and peer-reviewed publication. The risk of bias was addressed by including both quantitative and qualitative studies. RESULTS: Twenty-seven articles were included, mainly primary research articles. Common outcome measures included subjective self-reports and tests to measure eyestrain. Reaction time was also recorded, accounting for variables such as age and experience. One group recommended that guidelines should be implemented regarding number of hours worked. Most recommended ergonomic interventions, proposing the implementation of tools to measure and standardize fatigue and optimize workflow, in conjunction with considering radiologists individually. Education in appropriate viewing habits and breaks were also suggested. Only one study with seven participants recommended that radiologists should sleep well to improve their performance and overall well-being, despite the undeniable evidence that radiologists are fatigued. CONCLUSION: Fatigue is present in radiology and affects diagnostic accuracy.
